Abstract
Description
Technical Field
[0001] The present application relates to a valve, and particularly to a valve having multiple fluid channels. Background Art
[0002] In the cooling system of a vehicle, multiple fluid channels are usually provided and need to be switched according to different requirements to cool various heat-generating components in the vehicle. One control method is to use a valve for switching. The valve generally includes a housing and a valve body. The housing has several openings respectively for connecting several pipelines in the coolant flow path. An exemplary valve body has a valve body channel that can fluidly connect several openings on the housing; the valve body can rotate in the housing. By rotating the valve body, the relative position between the valve body channel in the valve body and the upper opening can change, so that the connection and disconnection between the valve body channel and the housing opening can be achieved, thereby different fluid channels can be formed to switch the coolant flow path.
[0003] The rotation of the valve body is usually driven by an actuator. To prevent coolant leakage during the rotation of the valve body, corresponding sealing is required, especially a seal needs to be provided between each housing opening and the valve body. However, the presence of the seal will increase the friction force when the valve body rotates, and the actuator that drives the rotation of the valve body needs to have a higher output power to overcome the friction force.
[0004] Existing actuators are usually small motors with limited output power. When the friction force is too large, a motor with a larger power or multiple actuators need to be selected. Especially with the development of new energy vehicles, the number of coolant flow paths that need to be adjusted in the vehicle increases, so that the number of openings and seals on the housing of the multi-channel valve also increases accordingly. Limited by power, the existing actuators are difficult to meet the requirements. Summary of the Invention
[0005] The valve provided by the present application can at least partially solve the above technical problems. By using an array of valve body components to respectively control an array of fluid channels, when switching the coolant flow path, only at least one group of the valve body components rotates, and the other one or more groups of valve body components remain stationary, which can effectively reduce the friction force when the valve body rotates, so that the control and switching of more groups of fluid channels can be achieved under the condition that the output power of the actuator is limited.
[0006] The present application provides a valve, which includes a housing, a drive shaft, and an array of valve body components disposed in the housing and capable of rotating in the housing. The drive shaft is configured to selectively drive at least one group of the valve body components in the array of valve body components to rotate. The valve is provided with a plurality of fluid channels, and the driven at least one group of valve body components can connect or disconnect at least one of the plurality of fluid channels.
[0007] According to the above valve, it further includes a plurality of clutch structures, and the drive shaft is configured to selectively engage or disengage at least one group of the valve body components in the array of valve body components with the drive shaft through at least one of the plurality of clutch structures.
[0008] According to the above valve, the array of valve body components is disposed at substantially the same height relative to the drive shaft.
[0009] According to the above valve, the array of valve body components is disposed at different heights relative to the drive shaft.
[0010] According to the above valve, each group of the array of valve body components includes one or more valve bodies, and the plurality of valve bodies are linked.
[0011] According to the above valve, the housing is provided with a plurality of housing openings configured to form the plurality of fluid channels. Each valve body component in the array of valve body components is provided with at least one valve body acting portion. When the driven at least one group of valve body components rotates by a predetermined angle, at least one valve body acting portion in the driven at least one group of valve body components and a corresponding one of the plurality of housing openings cooperate with each other, so as to selectively connect at least one fluid channel.
[0012] According to the above valve, the at least one valve body acting portion includes at least one valve body opening portion. When the driven at least one group of valve body components rotates by a predetermined angle, at least one valve body opening portion in the driven at least one group of valve body components and at least one of the plurality of housing openings cooperate with each other, so that the at least one valve body opening portion selectively at least partially opens at least one of the plurality of housing openings, thereby selectively connecting the at least one fluid channel.
[0013] According to the above valve, the valve body opening portion of the at least one valve body acting portion is an inlet or an outlet of a valve body channel in a corresponding valve body component, and the at least one fluid channel can be connected through the valve body channel.
[0014] According to the valve described above, the at least one valve body acting part includes at least one valve body blocking part. When the at least one set of valve body components being driven rotates by a predetermined angle, at least one valve body blocking part among the at least one set of valve body components being driven and at least one of the several housing openings cooperate with each other, so that at least one valve body blocking part selectively blocks at least one of the several housing openings, thereby selectively disconnecting the at least one fluid passage.
[0015] According to the valve described above, when the at least one valve body rotates by a predetermined angle, the at least one valve body acting part and at least one of the several housing openings can be aligned and cooperate with each other.
[0016] According to the valve described above, it further includes several seals, and the several seals are respectively arranged between each of the several housing openings and a corresponding one of the one or several valve body components.
[0017] According to the valve described above, the several clutch structures are configured such that when one set of the array of valve body components engages with the drive shaft, one or more other sets of the array of valve body components are separated from the drive shaft.
[0018] According to the valve described above, each of the several clutch structures includes a separable drive structure and a separable driven structure. The separable drive structure is arranged on the drive shaft, and the separable driven structure is arranged on a corresponding one of the array of valve body components.

[0065] The following will describe various specific embodiments of the present application with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", etc., are used in the present application to describe various exemplary structural parts and elements of the present application, these terms are used only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.
[0066] Ordinal numbers such as "first" and "second" used in the present application are only used for distinction and identification and do not have any other meanings. Without special indication, they do not represent a specific order and do not have a specific relevance. For example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component" either.
[0067] Figure 1A is a simplified schematic diagram of the first embodiment of the valve of the present application, showing a schematic structure from a side perspective; Figure 1B is Figure 1A The valve 100 shown along Figure 1A the center line A - A is a simplified cross-sectional structural schematic diagram. As Figure 1A and Figure 1B shown, the valve 100 includes a housing 101, and a housing cavity 102 is provided in the housing 101. Four housing openings are provided on the housing 101, namely a first housing opening 151, a second housing opening 152, a third housing opening 153, and a fourth housing opening 154. The housing cavity 102 can be in fluid communication with the outside of the valve 100 through any one of the first housing opening 151, the second housing opening 152, the third housing opening 153, and the fourth housing opening 154.
[0068] The valve 100 further includes a first set of valve body components 111 and a second set of valve body components 112. The first set of valve body components 111 and the second set of valve body components 112 are disposed in the housing cavity 102 of the housing 101. The first set of valve body components 111 includes a first valve body 121 and a second valve body 122. The first valve body 121 and the second valve body 122 are connected to each other and are capable of rotating together about the rotation axis 131 (i.e., being linked). Among them, the first valve body 121 is spherical and is provided with a first valve body passage (not shown). One end of the first valve body passage forms a valve body opening portion 161 on the first valve body 121. The first valve body passage can be in fluid communication with the housing cavity 102. When the valve body opening portion 161 on the first valve body 121 is aligned or partially aligned with the first housing opening 151, the first housing opening 151 is opened by the first valve body 121, and the housing cavity 102 can be in fluid communication with the outside through the valve body opening portion 161 and the first housing opening 151. When the valve body opening portion 161 on the first valve body 121 is not aligned with the first housing opening 151, the first housing opening 151 is closed or blocked by the first valve body 121, so that the housing cavity 102 cannot be in fluid communication with the outside through the valve body opening portion 161 and the first housing opening 151. The second valve body 122 is spherical and is provided with a second valve body passage (not shown). One end of the second valve body passage forms a valve body opening portion 162 on the second valve body 122. The second valve body passage can be in fluid communication with the housing cavity 102. When the valve body opening portion 162 on the second valve body 122 is aligned or partially aligned with the second housing opening 152, the second housing opening 152 is opened, and the housing cavity 102 can be in fluid communication with the outside through the valve body opening portion 162 and the second housing opening 152. When the valve body opening portion 162 on the second valve body 122 is not aligned with the second housing opening 152, the second housing opening 152 is closed or blocked by the second valve body 122, so that the housing cavity 102 cannot be in fluid communication with the outside through the valve body opening portion 162 and the second housing opening 152.
[0069] Similarly, the second set of valve body components 112 includes a third valve body 123 and a fourth valve body 124. The third valve body 123 and the fourth valve body 124 are connected to each other and are capable of rotating together about the rotation axis 132 (i.e., being interlocked). Among them, the third valve body 123 is spherical and is provided with a third valve body passage (not shown). One end of the third valve body passage forms a valve body opening portion 163 on the third valve body 123. The third valve body passage can be in fluid communication with the housing cavity 102. When the valve body opening portion 163 of the third valve body 123 is aligned or partially aligned with the third housing opening 153, the third housing opening 153 is opened by the third valve body 123, and the housing cavity 102 can be in fluid communication with the outside through the valve body opening portion 163 and the third housing opening 153. When the valve body opening portion 163 on the third valve body 123 is not aligned with the third housing opening 153, the third housing opening 153 is closed or blocked by the third valve body 123, so that the housing cavity 102 cannot be in fluid communication with the outside through the valve body opening portion 163 and the third housing opening 153. The fourth valve body 124 is spherical and is provided with a fourth valve body passage (not shown). One end of the fourth valve body passage forms a valve body opening portion 164 on the fourth valve body 124. The fourth valve body passage can be in fluid communication with the housing cavity 102. When the valve body opening portion 164 of the fourth valve body 124 is aligned or partially aligned with the fourth housing opening 154, the fourth housing opening 154 is opened by the fourth valve body 124, and the housing cavity 102 can be in fluid communication with the outside through the valve body opening portion 164 and the fourth housing opening 154. When the valve body opening portion 164 on the fourth valve body 124 is not aligned with the fourth housing opening 154, the fourth housing opening 154 is closed or blocked by the fourth valve body 124, so that the housing cavity 102 cannot be in fluid communication with the outside through the valve body opening portion 164 and the fourth housing opening 154.
[0070] The valve 100 further includes seals 171, 172, 173, 174. The seals 171, 172, 173, 174 are respectively disposed within the housing 101 and respectively surround the housing openings 151, 152, 153, 154 for sealing the gaps between the several housing openings 151, 152, 153, 154 and the corresponding one of the several valve bodies 121, 122, 123, 124.
[0071] The valve 100 further includes a drive device 180. The drive device 180 is used to drive the first set of valve body components 111 and the second set of valve body components 112 to rotate about the rotation axis 131 and the rotation axis 132 respectively. Specifically, the drive device 180 includes an actuator 190 and a drive shaft 118. The drive shaft 118 is connected to the actuator 190 so that the actuator 190 can drive the drive shaft 118 to rotate.
[0072] The valve 100 further includes a disc 140, a first clutch structure 141, and a second clutch structure 142. The disc 140 is fixedly connected to the drive shaft 118, and when the drive shaft 118 rotates, it can drive the disc 140 to rotate together.
[0073] Specifically, the first clutch structure 141 includes a first separable driving structure 181 and a first separable driven structure 191. The first separable driving structure 181 is disposed on the disc 140. The first separable driven structure 191 is disposed on the first valve body 121. The first separable driving structure 181 and the first separable driven structure 191 are configured to be able to cooperate with each other such that when the drive shaft 118 rotates within a first angular range, the drive shaft 118 can engage with the first group of valve body components 111, so that the first separable driving structure 181 on the drive shaft 118 can drive the first group of valve body components 111 to rotate.
[0074] The second clutch structure 142 includes a second separable driving structure 182 and a second separable driven structure 192. The second separable driving structure 182 is disposed on the disc 140. The second separable driven structure 192 is disposed on the second valve body 122. The second separable driving structure 182 and the second separable driven structure 192 are configured to be able to cooperate with each other such that when the drive shaft 118 rotates within a second angular range, the drive shaft 118 can engage with the second group of valve body components 112, so that the second separable driving structure 182 on the drive shaft 118 can drive the second group of valve body components 112 to rotate.
[0075] In an embodiment of the present application, Figure 1B the shown first separable driving structure 181 and second separable driving structure 182 are arranged on the same disc 140. However, those skilled in the art can understand that the first separable driving structure 181 and the second separable driving structure 182 can also be fixedly connected to the drive shaft 118 in other forms.
[0076] Figure 2 is Figure 1A - 1B a schematic diagram of an embodiment of the relationship between the rotation angle of the drive shaft 118 shown in and the opening degrees of the housing openings 151, 152, 153, 154. In Figure 2 the embodiment of, 100% angle means that the rotatable angle of the drive shaft 118 is 360°, when the housing openings 151, 152, 153, 154 are completely opened by the corresponding valve bodies, the opening degree is 100%, and when the housing openings 151, 152, 153, 154 are completely closed or blocked by the corresponding valve bodies, the opening degree is 0%. Those skilled in the art can understand that the 100% angle can also mean that the rotatable angle of the drive shaft 118 is 90°, 180°, or any other angle.
[0077] As Figure 2 shown, when the drive shaft 118 rotates within the angular range of 0 - 25%, the aligned area between the valve body opening portion 161 of the first valve body 121 and the first housing opening 151 gradually increases, so that the opening degree of the first housing opening 151 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angular range of 25 - 100%, the valve body opening portion 161 of the first valve body 121 and the first housing opening 151 are always aligned, and the opening degree of the first housing opening 151 remains 100%.
[0078] Similarly, for the second housing opening 152, when the drive shaft 118 rotates within the angular range of 0 - 50%, the aligned area between the valve body opening portion 162 of the second valve body 122 and the second housing opening 152 is 0%, the second housing opening 152 is closed or blocked by the second valve body 122, and the opening degree of the second housing opening 152 remains 0%. When the drive shaft 118 rotates within the angular range of 50 - 75%, the aligned area between the valve body opening portion 162 of the second valve body 122 and the second housing opening 152 gradually increases, so that the opening degree of the second housing opening 152 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angular range of 75 - 100%, the valve body opening portion 162 of the second valve body 122 and the second housing opening 152 are always aligned, and the opening degree of the second housing opening 152 remains 100%.
[0079] Similarly, for the third housing opening 153, when the drive shaft 118 rotates within the angular range of 0 - 25%, the aligned area between the valve body opening portion 163 of the third valve body 123 and the third housing opening 153 is 0%, the third housing opening 153 is closed or blocked by the third valve body 123, and the opening degree of the third housing opening 153 remains 0%. When the drive shaft 118 rotates within the angular range of 25 - 50%, the aligned area between the valve body opening portion 163 of the third valve body 123 and the third housing opening 153 gradually increases, so that the opening degree of the third housing opening 153 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angular range of 50 - 100%, the valve body opening portion 163 and the third housing opening 153 are always aligned, and the opening degree of the third housing opening 153 remains 100%.
[0080] Similarly, for the fourth housing opening 154, when the drive shaft 118 rotates within the angular range of 0 - 75%, the aligned area between the valve body opening portion 164 of the fourth valve body 124 and the fourth housing opening 154 is 0%, and the fourth housing opening 154 is closed or blocked by the fourth valve body 124, with the opening degree remaining 0%. When the drive shaft 118 rotates within the angular range of 75 - 100%, the aligned area between the valve body opening portion 164 of the fourth valve body 124 and the fourth housing opening 154 gradually increases, causing the opening degree of the fourth housing opening 154 to gradually change from 0% to 100%.
[0081] To achieve Figure 2 the opening degree control shown, the valve 100 can be configured such that when the drive shaft 118 rotates within the angular ranges of 0 - 25% and 50 - 75%, the first valve body 121 and the second valve body 122 are driven by the drive shaft 118 to rotate, while the third valve body 123 and the fourth valve body 124 are not driven by the drive shaft 118 to rotate; when the drive shaft 118 rotates within the angular ranges of 25 - 50% and 75 - 100%, the first valve body 121 and the second valve body 122 are not driven by the drive shaft 118 to rotate, while the third valve body 123 and the fourth valve body 124 are driven by the drive shaft 118 to rotate. That is to say, when the drive shaft 118 rotates within the angular ranges of 0 - 25% and 50 - 75%, the drive shaft 118 meshes with the first group of valve body components 111 but separates from the second group of valve body components 112; when the drive shaft 118 rotates within the angular ranges of 25 - 50% and 75 - 100%, the drive shaft 118 separates from the first group of valve body components 111 but meshes with the second group of valve body components 112.
[0082] The respective housing openings 151, 152, 153, 154 of the valve 100 are respectively connected to the external pipelines. By controlling the rotation of each valve body 121, 122, 123, and 124 relative to the housing 101, the opening and closing states of the respective housing openings 151, 152, 153, 154 can be controlled. By controlling the opening and closing states of the respective housing openings 151, 152, 153, 154 and the mutual cooperation between the valve bodies 121, 122, 123, and 124, several fluid channels can be formed in the valve 100, and each fluid channel is used to connect two corresponding housing openings. Thus, through this fluid channel, the external pipelines connected to these two corresponding housing openings can be connected. The several fluid channels in the valve 100 can be switched on or off by controlling the rotation of each valve body.
[0083] To better illustrate the fluid channels inside the valve, the following will be combined with Figure 1A and Figure 2 the states when the drive shaft 118 is at angles of 50% and 75% respectively as examples for explanation:
[0084] If the first housing opening 151 is connected to the coolant inlet pipeline, and the other three housing openings 152, 153, 154 are respectively connected to three coolant outlet pipelines, then the valve 100 can be configured such that three fluid channels A, B, and C can be formed in the valve 100. Among them, the fluid channel A connects the first housing opening 151 and the second housing opening 152, the fluid channel B connects the first housing opening 151 and the third housing opening 153, and the fluid channel C connects the first housing opening 151 and the fourth housing opening 154.
[0085] When the drive shaft 118 is at an angle of 50%, the valve body opening portion 161 on the first valve body 121 is aligned with the first housing opening 151, so that the first housing opening 151 is opened; the valve body opening portion 163 on the third valve body 123 is aligned with the third housing opening 153, so that the third housing opening 153 is opened; while the valve body opening portion 162 on the second valve body 122 is not aligned with the second housing opening 152, so that the second housing opening 152 is closed or blocked, and the valve body opening portion 164 of the fourth valve body 124 is not aligned with the fourth housing opening 154, so that the fourth housing opening 154 is closed or blocked. At this time, the fluid channel B connecting the first housing opening 151 and the third housing opening 153 is connected, while the fluid channel A connecting the first housing opening 151 and the second housing opening 152, and the fluid channel C connecting the first housing opening 151 and the fourth housing opening 154 are disconnected.
[0086] When the drive shaft 118 is at an angle of 75%, the valve body opening portion 161 on the first valve body 121 is aligned with the first housing opening 151, so that the first housing opening 151 is opened; the valve body opening portion 162 on the second valve body 122 is aligned with the second housing opening 152, so that the second housing opening 152 is opened; the valve body opening portion 163 on the third valve body 123 is aligned with the third housing opening 153, so that the third housing opening 153 is opened; while the valve body opening portion 164 of the fourth valve body 124 is not aligned with the fourth housing opening 154, so that the fourth housing opening 154 is closed or blocked. At this time, the fluid channel B connecting the first housing opening 151 and the third housing opening 153, and the fluid channel A connecting the first housing opening 151 and the second housing opening 152 are connected, while the fluid channel C connecting the first housing opening 151 and the fourth housing opening 154 is disconnected.
[0087] It should be noted that in the first embodiment, the valve body opening portions 161, 162, 163, 164 on each valve body form a valve body acting portion, which is used to cooperate with a corresponding one of several housing openings when the driven valve body component rotates by a predetermined angle, so as to selectively connect at least one fluid passage. In other embodiments, the valve body acting portion may also be a valve body blocking portion, which is used to cooperate with at least one of several housing openings when the driven valve body component rotates by a predetermined angle, so that the valve body blocking portion selectively blocks at least one of several housing openings, thereby selectively disconnecting at least one fluid passage. This will be specifically described in the Figure 25A - 25C embodiment shown.
[0088] Figure 3 is a simplified schematic diagram of the second embodiment of the valve of the present application. Figure 3 The valve 300 shown in Figure 1A - 1B is the same as the valve 100 shown in Figure 3 and will not be described in detail here. Figure 1A - 1B The differences between the valve 300 shown in Figure 1A - 1B and the valve 100 shown in Figure 3 are as follows:
[0089] Specifically, Figure 3 the valve 300 shown in
[0090] includes a shaft 331 and a first clutch structure 141. The shaft 331 is coaxially arranged with the rotation axis 131. The first clutch structure 141 includes a first separable driving structure 381 and a first separable driven structure 391. Among them, the first separable driving structure 381 is arranged on the disc 140. The first separable driven structure 391 is arranged on the shaft 331 and is fixedly connected to the shaft 331. The first group of valve body components 111 is also fixedly connected to the shaft 331, so that when the driving shaft 118 rotates within the first angle range, the driving shaft 118 can engage with the first group of valve body components 111, so that the first separable driving structure 381 on the driving shaft 118 can drive the first group of valve body components 111 to rotate.Similarly, the valve 300 also includes a shaft 232 and a second clutch structure 142. The shaft 332 is coaxially arranged with the rotation axis 132. The second clutch structure 142 includes a second separable driving structure 382 and a second separable driven structure 392. Among them, the second separable driving structure 382 is arranged on the disc 140. The second separable driven structure 392 is arranged on the shaft 332 and is fixedly connected to the shaft 332. The second group of valve body components 112 is also fixedly connected to the shaft 232, so that when the drive shaft 118 rotates within the second angular range, the drive shaft 118 can engage with the second group of valve body components 112, so that the second separable driving structure 38 on the drive shaft 118 can drive the second group of valve body components 112 to rotate.
[0091] Figure 4 is a simplified schematic diagram of the third embodiment of the valve of the present application. Figure 4 The valve 400 shown is the same as the valve 100 shown in Figure 1A - 1B and will not be described in detail here. Figure 4 The valve 400 shown is different from the valve 100 shown in Figure 1A - 1B in that: Figure 4 the first valve body 421, the second valve body 422, the third valve body 423, and the fourth valve body 424 in the valve 400 shown are hemispherical, while Figure 1A - 1B the first valve body 121, the second valve body 122, the third valve body 123, and the fourth valve body 124 in the valve 100 shown are spherical.
[0092] It should be noted that the shape of the valve body is not limited to the spherical and hemispherical shapes shown in the present application, but can be any shape as long as there is a valve body channel and a corresponding valve body opening part inside the valve body.
[0093] Figure 5A is a simplified schematic diagram of the fourth embodiment of the valve of the present application, showing a schematic structure in side perspective; Figure 5B is Figure 5A a simplified cross-sectional structure schematic diagram of the valve 500 shown along Figure 5A the center line B-B. Figure 5A - 5B The valve 500 shown is the same as the valve 100 shown in Figure 1A - 1B and will not be described in detail here. Figure 5A - 5B The valve 500 shown is different from the valve 100 shown in Figure 1A - 1B mainly in that: Figure 5A - 5B the valve 500 shown also includes a third group of valve body components 513 and a third clutch structure 543 cooperating therewith.
[0094] Specifically, the third group of valve body components 513 includes a fifth valve body 525 and a sixth valve body 526. The fifth valve body 525 and the sixth valve body 526 are connected to each other and are capable of rotating together about the rotation axis 533. Among them, both the fifth valve body 525 and the sixth valve body 526 are spherical and have their respective valve body channels (not shown). One end of the valve body channels (not shown) forms a valve body opening portion 565 and a valve body opening portion 566 on the fifth valve body 525 and the sixth valve body 526 respectively.
[0095] Correspondingly, the housing 501 further includes a fifth housing opening 555 and a sixth housing opening 556, which can be aligned with the valve body opening portions 565, 566 of the third group of valve body components 513 respectively. A seal 475 is provided between the fifth housing opening 555 and the fifth valve body 525, and a seal (not shown) is provided between the sixth housing opening 556 and the sixth valve body 526.
[0096] In addition, the valve 500 further includes a third clutch structure 543. The third clutch structure 543 includes a third separable driving structure 582 and a third separable driven structure 592. The third separable driving structure 582 is provided on the disc 140. The third separable driven structure 592 is provided on the fifth valve body 525 of the third group of valve body components 513. The third separable driving structure 582 and the third separable driven structure 592 are configured to be able to cooperate with each other so that when the drive shaft 118 rotates within the third angle range, the drive shaft 118 can engage with the third group of valve body components 513, so that the third separable driving structure 582 on the drive shaft 118 can drive the third group of valve body components 513. Among them, the first clutch structure 141, the second clutch structure 142 and the third clutch structure 543 are arranged at the same height relative to the drive shaft 118.
[0097] In Figure 1A - Figure 5B the illustrated embodiment, each clutch structure and the array of valve body components are arranged at substantially the same height relative to the drive shaft 118. Such an arrangement can make the height of the valve 100 smaller, so that it can be applicable to application environments where the height of the valve is limited.
[0098] Figure 6A is a simplified schematic diagram of the fifth embodiment of the valve of the present application, showing the schematic structure from a side perspective; Figure 6B is Figure 6A the simplified cross-sectional structure schematic diagram of the illustrated valve 600 along Figure 6A the center line C-C. Figure 6A - 6B The same parts of the illustrated valve 600 and Figure 1A - 1B the valve 100 shown in Figure 6A - 6B are not described herein again. Figure 1A - 1B The differences between the illustrated valve 600 andFigure 6A - 6B In each group of valve body components in the array of valve body components in the shown valve 600, each group of valve body components includes only one valve body component, and each group of valve body components and their corresponding clutch structures are arranged at different heights relative to the drive shaft 118.
[0099] Specifically, the valve 600 includes a first valve body 621, a second valve body 622, a third valve body 623, a fourth valve body 624, and a first clutch structure 641, a second clutch structure 642, a third clutch structure 643, and a fourth clutch structure 644 correspondingly arranged therewith. Among them, the specific cooperation relationships between the first valve body 621, the second valve body 622, the third valve body 623, and the fourth valve body 624 and the housing 601 are substantially the same. The following takes the specific cooperation relationship between the first valve body 621, the first clutch structure 641, and the housing 601 as an example for description:
[0100] The first valve body 621 is spherical and can rotate around the rotation axis 631. A valve body opening portion 661 is provided on the first valve body 621 and can be aligned with the first housing opening 651 on the housing 601. A seal 671 is arranged in the housing 601 and is arranged around the housing opening 651 for sealing the gap between the first housing opening 651 and the first valve body 621.
[0101] The first clutch structure 641 includes a first separable driving structure 681 and a first separable driven structure 691. The first separable driving structure 681 is arranged on the disc 611. The first separable driven structure 691 is arranged on the first valve body 621. The first separable driving structure 681 and the first separable driven structure 691 are configured to be able to cooperate with each other so that when the drive shaft 118 rotates within the first angular range, the drive shaft 118 can engage with the first valve body 621, so that the first separable driving structure 681 on the drive shaft 118 can drive the first valve body 621 to rotate.
[0102] Similarly, the second clutch structure 642, the third clutch structure 643, and the fourth clutch structure 644 are configured to be able to engage with the second valve body 622, the third valve body 623, and the fourth valve body 624 respectively when the drive shaft 118 rotates within the second angular range, the third angular range, and the fourth angular range, so as to drive the second valve body 622, the third valve body 623, and the fourth valve body 624 to rotate, so that the valve body opening portions on the first valve body 621, the second valve body 622, the third valve body 623, and the fourth valve body 624 can be aligned with the first housing opening 651, the second housing opening 652, the third housing opening 653, and the fourth housing opening 654 respectively.
[0103] Figure 7 is Figure 6A - 6BSchematic diagram of an embodiment showing the relationship between the rotation angle of the drive shaft 118 and the opening degrees of the housing openings 651, 652, 653, 654. In Figure 7 In the embodiment of, 100% angle means that the rotatable angle of the drive shaft 118 is 360°. When the housing openings 651, 652, 653, 654 are fully opened by the corresponding valve bodies, the opening degree is 100%, and when the housing openings 651, 652, 653, 654 are fully closed or blocked by the corresponding valve bodies, the opening degree is 0%. Those skilled in the art can understand that the 100% angle can also mean that the rotatable angle of the drive shaft 118 is 90°, 180° or any other angle.
[0104] As Figure 7 shown, when the drive shaft 118 rotates within the angle range of 0 - 25%, the aligned area between the valve body opening portion 661 of the first valve body 621 and the first housing opening 651 gradually increases, so that the opening degree of the first housing opening 651 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angle range of 25 - 100%, the valve body opening portion 661 of the first valve body 621 and the first housing opening 651 are always aligned, and the opening degree of the first housing opening 651 remains 100%.
[0105] Similarly, for the second housing opening 652, when the drive shaft 118 rotates within the angle range of 0 - 50%, the aligned area between the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 is 0%, the second housing opening 652 is closed or blocked by the second valve body 622, and the opening degree of the second housing opening 652 remains 0%. When the drive shaft 118 rotates within the angle range of 50 - 75%, the aligned area between the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 gradually increases, so that the opening degree of the second housing opening 652 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angle range of 75 - 100%, the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 are always aligned, and the opening degree of the second housing opening 652 remains 100%.
[0106] Similarly, for the third housing opening 653, when the drive shaft 118 rotates within the angular range of 0 - 25%, the aligned area between the valve body opening portion 663 of the third valve body 623 and the third housing opening 653 is 0%. The third housing opening 653 is closed or blocked by the third valve body 623, and the opening degree of the third housing opening 653 remains 0%. When the drive shaft 118 rotates within the angular range of 25 - 50%, the aligned area between the valve body opening portion 663 of the third valve body 623 and the third housing opening 653 gradually increases, so that the opening degree of the third housing opening 653 gradually changes from 0% to 100%. When the drive shaft 118 rotates within the angular range of 50 - 100%, the valve body opening portion 663 and the third housing opening 653 are always aligned, and the opening degree of the third housing opening 653 remains 100%.
[0107] Similarly, for the fourth housing opening 654, when the drive shaft 118 rotates within the angular range of 0 - 75%, the aligned area between the valve body opening portion 664 of the fourth valve body 624 and the fourth housing opening 654 is 0%. The fourth housing opening 654 is closed or blocked by the fourth valve body 124, and the opening degree remains 0%. When the drive shaft 118 rotates within the angular range of 75 - 100%, the aligned area between the valve body opening portion 664 of the fourth valve body 624 and the fourth housing opening 654 gradually increases, so that the opening degree of the fourth housing opening 654 gradually changes from 0% to 100%.
[0108] To achieve Figure 2As shown in the opening degree control, the valve 100 can be configured such that when the drive shaft 118 rotates within an angular range of 0 - 25%, the drive shaft 118 engages with the first valve body 621, but is separated from the second valve body 622, the third valve body 623, and the fourth valve body 624, so that the first valve body 621 is driven by the drive shaft 118 to rotate, while the second valve body 622, the third valve body 623, and the fourth valve body 624 are not driven by the drive shaft 118 to rotate; when the drive shaft 118 rotates within an angular range of 25 - 50%, the drive shaft 118 engages with the third valve body 623, but is separated from the first valve body 621, the second valve body 622, and the fourth valve body 624, so that the third valve body 623 is driven by the drive shaft 118 to rotate, while the first valve body 621, the second valve body 622, and the fourth valve body 624 are not driven by the drive shaft 118 to rotate; when the drive shaft 118 rotates within an angular range of 50 - 75%, the drive shaft 118 engages with the second valve body 622, but is separated from the first valve body 621, the third valve body 623, and the fourth valve body 624, so that the second valve body 622 is driven by the drive shaft 118 to rotate, while the first valve body 621, the third valve body 623, and the fourth valve body 624 are not driven by the drive shaft 118 to rotate; when the drive shaft 118 rotates within an angular range of 75 - 100%, the drive shaft 118 engages with the fourth valve body 6243, but is separated from the first valve body 621, the second valve body 622, and the third valve body 623, so that the fourth valve body 624 is driven by the drive shaft 118 to rotate, while the first valve body 621, the second valve body 622, and the third valve body 623 are not driven by the drive shaft 118 to rotate.
[0109] The respective housing openings 651, 652, 653, 654 of the valve 600 are respectively connected to external pipelines. By controlling the rotation of each of the valve bodies 621, 622, 623, 624 relative to the housing 101, the opening and closing states of the respective housing openings 651, 652, 653, 654 can be controlled. By controlling the opening and closing states of the respective housing openings 651, 652, 653, 654 and the mutual cooperation between the valve bodies 621, 622, 623, 624, several fluid channels can be formed in the valve 600, and each fluid channel is used to connect two corresponding housing openings. Thus, through this fluid channel, the external pipelines connected to these two corresponding housing openings can be connected. The several fluid channels in the valve 600 can be switched on or off by controlling the rotation of each valve body.
[0110] Figure 8 It is a simplified schematic diagram of the sixth embodiment of the valve of the present application. Figure 8 The valve 800 shown is the same as Figure 6A - 6B the valve 600 shown in, and details will not be repeated here. Figure 8 The valve 800 shown is the same as Figure 6A - 6BThe valve 600 shown is different in that: Figure 8 The first valve body 821, the second valve body 822, the third valve body 823, and the fourth valve body 824 in the valve 800 shown are hemispherical, while Figure 6A - 6B The first valve body 621, the second valve body 622, the third valve body 623, and the fourth valve body 624 in the valve 600 shown are spherical.
[0111] Figure 9 is a simplified schematic diagram of the seventh embodiment of the valve of the present application. As Figure 9 shown, the valve 900 includes six groups of valve body components. Each of the first group of valve body components 911 and the second group of valve body components 912 includes two interconnected valve bodies. The cooperation relationship between the first group of valve body components 911 and the second group of valve body components 912, the clutch structure, and the housing 901 is similar to that of the Figure 1A - 1B valve 100 in, and will not be elaborated here.
[0112] The valve 900 further includes another four groups of valve body components. Each group of valve body components in these four groups of valve body components includes only one valve body component, and the clutch structures corresponding to each group of valve body components are arranged at different heights relative to the drive shaft 118. Specifically, the valve body components included in these four groups of valve body components are: the third valve body component 921, the fourth valve body component 922, the fifth valve body component 923, and the sixth valve body component 924. The cooperation relationship between the third valve body component 921, the fourth valve body component 922, the fifth valve body component 923, and the sixth valve body component 924, the clutch structure, and the housing 901 is similar to that of the Figure 6A - 6B valve 600 in, and will not be elaborated here.
[0113] Figure 10 is Figure 9 a schematic diagram of an embodiment of the relationship between the rotation angle of the drive shaft 118 shown in and the opening degrees of the housing openings 151, 152, 153, 154, 651, 652, 653, 654. Figure 10 The relationship between the rotation angle of the drive shaft 118 shown and the housing openings 151, 152, 153, 154, 651, 652, 653, 654 is similar to that of Figure 2 and Figure 7 and can also achieve the flow or disconnection of different fluid channels in the valve body 900 by opening and closing the housing openings 151, 152, 153, 154, 651, 652, 653, 654, and will not be elaborated here.
[0114] In Figure 6A - Figure 10 the embodiment shown, the respective clutch structures are arranged at different heights relative to the drive shaft 118. Such an arrangement can make the circumferential dimension of the valve 100 smaller, so that it can be applicable to the application environment where the circumferential dimension of the valve is limited.
[0115] It should be noted that although Figure 1A to Figure 10 in the illustrated embodiments, only one valve body opening portion is provided on each valve body component, those skilled in the art can understand that multiple valve body opening portions can also be provided on each valve body component, so that different valve body opening portions can function when the drive shaft rotates to different angular ranges.
[0116] Figure 1A to Figure 10 The valves shown can all selectively drive at least one group of valve bodies in several groups of valve body components to rotate through several clutch structures, so as to connect or disconnect at least one fluid passage among several fluid passages in the valve body. Since the drive shaft only needs to selectively drive at least one group of valve bodies in several groups of valve body components to rotate at the same time, the drive shaft only needs to overcome the friction force generated by the seal between the at least one group of valve bodies driven and the housing. Therefore, when the output power of the actuator 190 is relatively small, it can also drive the rotation of the valve body provided with multiple seals. When a valve needs to provide more fluid passages, more housing openings need to be provided on the housing of the valve, and the more housing openings there are, the more seals there are. When the output power of the actuator is certain, the valve provided by the present application is particularly suitable for applications that provide more fluid passages, because the drive shaft of the valve of the present application only needs to overcome the friction force generated by the seal between the at least one group of valve bodies driven and the housing, and does not need to overcome the friction forces generated by the seals between all valve bodies and the housing at the same time. Therefore, it is not necessary to increase the output power of the actuator 190 as the number of fluid passages in the valve increases.
[0117] The following will combine Figure 11A - Figure 24 to show the cooperation relationship between the housing, the valve body component and the clutch structure through a specific embodiment.
[0118] Figure 11A is a perspective view of the valve 1100 according to the eighth embodiment of the present application; Figure 11B is Figure 11A the exploded view of the valve 1100 shown; Figure 11C is Figure 11A the valve 1100 shown along Figure 11A the vertical downward sectional view along the D-D section line in Figure 11A - 11C In order to clearly show the main components in the valve 1100, Figure 11A - 11CAs shown, valve 1100 includes a housing 1101, a first valve body 1132, a second valve body 1134, a third valve body 1136, and a fourth valve body 1138. The housing 1101 has a first cavity 1112 and a second cavity 1114. The first valve body 1132, the second valve body 1134, and the fourth valve body 1138 are disposed in the first cavity 1112, and the third valve body 1136 is disposed in the second cavity 1114. A sleeve 1155 is provided at the bottom of the rotating shaft 1162 of the first valve body 1132, and the sleeve 1155 is sleeved on the top of the rotating shaft 1164 of the second valve body 1134, so that the first valve body 1132 and the second valve body 1134 can rotate about the same first axis X. The lower part of the rotating shaft 1166 of the third valve body 1136 passes through the first transverse partition plate 1120 of the first cavity 1112 and the second cavity 1114 and then extends into the first cavity 1112. A sleeve 1156 is provided at the bottom of the third valve body 1136, and the sleeve 1156 is sleeved on the top of the rotating shaft 1168 of the fourth valve body 1138, so that the third valve body 1136 and the fourth valve body 1138 can rotate about the same second axis Y.
[0119] The valve 1100 further includes a drive shaft 1118. The drive shaft 1118 is disposed in the first cavity 1112 and can rotate about a third axis Z. The first valve body 1132 and the second valve body 1134 are disposed on the left side of the drive shaft 1118, and the third valve body 1136 and the fourth valve body 1138 are disposed on the right side of the drive shaft 1118. The valve 1100 further includes a first clutch structure, a second clutch structure, a third clutch structure, and a fourth clutch structure. When the drive shaft 1118 rotates, the first valve body 1132, the second valve body 1134, the third valve body 1136, and the fourth valve body 1138 can selectively rotate together with the drive shaft 1118 through the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure respectively.
[0120] Figure 12 is Figure 11A an exploded view of the housing 1101 shown. As Figure 12 shown, the housing 1101 includes a housing body 1202 and a cover 1203. The size of the cover 1203 can match the size of the pipe opening 1375 of the pipe 1370 in the housing body 1202, so that the cover 1203 can be installed on the pipe opening 1375 and block the pipe opening 1375, so that the housing 1101 cannot flow in or out from the pipe opening 1375.
[0121] Figure 13A is a perspective view of the housing body 1202 shown looking down from the front of the housing 1101; Figure 12 shown; Figure 13B is a perspective view of the housing body 1202 shown looking up from the back of the housing 101; Figure 12 shown.Figure 13C and 13D are respectively Figure 12 the top view and the bottom view of the housing main body 1202 shown in the figure. Figure 13E is Figure 12 the vertical downward sectional view of the housing main body 1202 shown in the figure along the Figure 13A section line E-E in the figure to show more structural details inside the housing main body 1202. To better describe the structure of the housing main body 1202, in this application, the extending direction of the first axis X, the second axis Y and the third axis Z is taken as the first direction, the horizontal connection direction of the first axis X and the third axis Z is taken as the second direction, and the direction perpendicular to the first direction and the second direction is taken as the third direction.
[0122] As Figure 13A - 13E shown in the figure, the housing main body 1202 has a top plate. The top plate includes a first transverse partition plate 1120, a second transverse partition plate 1323 and a vertical partition plate 1324. The first transverse partition plate 1120 and the second transverse partition plate 1323 are arranged to have a height difference in the first direction to form a step portion 1301. A first cavity 1112 is provided below the first transverse partition plate 1120 and the second transverse partition plate 1323, and a second cavity 1114 is provided above the first transverse partition plate 1120, so that the top of the second cavity 1114 is partially higher than the top of the first cavity 1112 in the first direction.
[0123] A perforation 1391 is provided in the first transverse partition plate 1120. The lower part of the third valve body 1136 can pass through the perforation 1391, so that the lower part of the third valve body 1136 extends into the first cavity 1112, and the third valve body 1136 can rotate around the second axis Y.
[0124] The first bottom plate 1395 of the first cavity 1112 has a concave portion 1396 for receiving the lower part of the fourth valve body 1138. Since the upper part of the fourth valve body 1138 is connected to the lower part of the third valve body 1136, and the lower part of the fourth valve body 1138 is received in the concave portion 1396 of the first bottom plate 1395, the fourth valve body 1138 can be arranged in the first cavity 1112 and can rotate around the second axis Y.
[0125] The second transverse partition plate 1323 has a concave portion 1393 for receiving the upper part of the first valve body 1132. The second bottom plate 1397 of the first cavity 1112 has a concave portion 1398 for receiving the lower part of the second valve body 1134. Since the lower part of the first valve body 1132 and the upper part of the second valve body 1134 are sleeved together, the first valve body 1132 and the second valve body 1134 can be arranged in the first cavity 1112 together and can rotate around the first axis X.
[0126] The second horizontal partition plate 1323 also has a concave portion 1394 for receiving the upper part of the drive shaft 1118, so that when the actuator drives the drive shaft 1118 to rotate, the drive shaft 1118 can rotate about the third axis Z.
[0127] Figure 13F is Figure 12 a sectional view of the shown housing body 1202 along the Figure 13A parallel direction of the F-F section line in the figure to more clearly show the shape of the first cavity 1112. As Figure 13F shown, the shape of the first cavity 1112 is generally three intersecting cylinders, thus forming a first cut cylinder cavity 1311, a second cut cylinder cavity 1312 and a third cut cylinder cavity 1313. The first valve body 1132 and the second valve body 1134 are arranged in the first cut cylinder cavity 1311, the drive shaft 1118 is arranged in the second cut cylinder cavity 1312, and the fourth valve body 1138 is arranged in the third cut cylinder cavity 1313. Among them, the central axis M of the first cut cylinder cavity 1311 coincides with the first axis X, the central axis N of the second cut cylinder cavity 1312 coincides with the third axis Z, and the central axis O of the third cut cylinder cavity 1313 coincides with the second axis Y.
[0128] Combined Figure 13A - 13E it can be seen that a first group of housing openings are provided on the cavity wall of the first cavity 1112. The first group of housing openings includes a first housing opening 1361 arranged along the third direction and a second housing opening 1362 arranged in the reverse direction of the third direction. The first housing opening 1361 and the second housing opening 1362 have the same setting height in the first direction, and the heights of the first housing opening 1361 and the second housing opening 1362 are set to enable the first housing opening 1361 and the second housing opening 1362 to cooperate with the first valve body 1132. In other words, when the first valve body 1132 rotates, it can selectively connect or disconnect the first housing opening 1361 and / or the second housing opening 1362.
[0129] The first group of housing openings also includes a third housing opening 1363, which is arranged within the range of the included angle between the reverse direction of the second direction and the third direction, and its setting height in the first direction is lower than that of the first housing opening 1361 and the second housing opening 1362. The height of the third housing opening 1363 is set to enable the third housing opening 1363 to cooperate with the second valve body 1134. In other words, when the second valve body 1134 rotates, it can selectively connect or disconnect the third housing opening 1363.
[0130] The first set of housing openings further includes a fourth housing opening 1364, which is arranged within the range of the included angle between the reverse direction of the second direction and the reverse direction of the third direction, and is slightly lower than the third housing opening 1363 in the first direction. The installation height of the fourth housing opening 1364 is lower than the installation height of the second valve body 1134. In other words, no matter what angle the second valve body 1134 rotates to, the fourth housing opening 1364 remains in fluid communication with the first cavity 1112.
[0131] Among them, each of the first housing opening 1361, the second housing opening 1362, the third housing opening 1363, and the fourth housing opening 1364 is arranged around the first cut cylindrical cavity 1311 with the central axis M of the first cut cylindrical cavity 1311 as the third direction.
[0132] The first set of housing openings further includes a fifth housing opening 1365, which is arranged within the range of the included angle between the reverse direction of the third direction and the second direction, and is slightly lower than the second housing opening 1362 in the first direction. The height of the fifth housing opening 1365 is set to enable the fifth housing opening 1365 to cooperate with the fourth valve body 1138. In other words, when the fourth valve body 1138 rotates, the fifth housing opening 1365 can be selectively connected or disconnected. In addition, the fifth housing opening 1365 is arranged around the third cut cylindrical cavity 1313 with the central axis O of the third cut cylindrical cavity 1313 as the third direction.
[0133] Each of the first housing opening 1361, the second housing opening 1362, the third housing opening 1363, the fourth housing opening 1364, and the fifth housing opening 1365 has a pipe arranged around it and extending outward from the housing body 1202, so that each housing opening can be connected to other devices or pipes through the pipe.
[0134] Figure 13G is Figure 12 The sectional view of the housing body 1202 shown along Figure 13D the G-G section line in the figure to show the specific arrangement of the sixth housing opening 1366 and its pipe. As Figure 13GAs shown, the first set of housing openings further includes a sixth housing opening 1366, which is arranged at the junction of the cavity wall of the first cut cylinder cavity 1311 and the cavity wall of the second cut cylinder cavity 1312. The sixth housing opening 1366 is arranged within the range of the included angle between the reverse of the third direction and the second direction, and its setting height in the first direction is slightly lower than that of the second housing opening 1362. The height of the sixth housing opening 1366 is set to enable the sixth housing opening 1366 to cooperate with the second valve body 1134. In other words, when the second valve body 1134 rotates, the sixth housing opening 1366 can be selectively connected or disconnected.
[0135] Combined Figure 12 Viewed, a pipe 1370 is arranged around the sixth housing opening 1366 and extends outward from the housing body 1202. The pipe opening 1375 of the pipe 1370 is blocked by a cover 1203 so that fluid cannot flow into or out of the housing body 1202 from the pipe opening 1375. The housing body 1202 further includes a pipe 1371 arranged perpendicular to the pipe 1370. The pipe 1371 is in fluid communication with the pipe 1370. In this way, the fluid flowing out of or into the housing body 1202 from the sixth housing opening 1366 can flow through the pipe openings 1373, 1374 of the pipe 1371.
[0136] Continuing to refer to FIGS. 13A - 13E, a second set of housing openings is provided on the cavity wall of the second cavity 1114. The second set of housing openings includes a seventh housing opening 1367 and an eighth housing opening 1368. The seventh housing opening 1367 is arranged within the range of the included angle between the second direction and the third direction, and its setting height in the first direction is higher than that of the fourth housing opening 1364. The eighth housing opening 1368 is arranged within the range of the included angle between the reverse of the third direction and the second direction, and its setting height in the first direction is slightly lower than that of the seventh housing opening 1367. The heights of the seventh housing opening 1367 and the eighth housing opening 1368 are set to enable the seventh housing opening 1367 and the eighth housing opening 1368 to cooperate with the third valve body 1136. In other words, when the third valve body 1136 rotates, the seventh housing opening 1367 and / or the eighth housing opening 1368 can be selectively connected or disconnected.
[0137] Each of the seventh housing opening 1367 and the eighth housing opening 1368 has a pipe arranged around it and extending outward from the housing body 1202, so that each housing opening can be connected to other devices or pipes through the pipe.
[0138] The second set of housing openings further includes a pump outlet housing opening 1369. The pump outlet housing opening 1369 is provided on the vertical partition plate 1324 and is used to connect to a pump outlet (not shown). Specifically, the pump outlet housing opening 1369 is arranged within the range of the included angle between the reverse of the second direction and the reverse of the third direction, and the height of the pump outlet housing opening 1369 is set to enable the pump outlet housing opening 1369 to cooperate with the third valve body 1136. In other words, when the third valve body 1136 rotates, it can selectively connect or disconnect the pump outlet housing opening 1369.
[0139] As an example, the valve 1100 in the present application uses a pump (not shown) as the power source for fluid flow. As Figure 13A shown, there are several through holes 1342 on the second transverse partition plate 1323 at the top of the first cavity 1112, which are used to connect to the inlet of the pump. The opening 1399 at the top of the second cavity 1114 can be covered by the pump. In this way, the fluid in the first cavity 1112 can flow out of the housing 1101 through several holes 1242 and then enter the pump, and the fluid flowing out through the pump outlet can enter the second cavity 1114 through the pump outlet housing opening 1369.
[0140] As an example, an actuator (not shown) is used as the power source for driving the rotation of the drive shaft 1118 in the present application. As Figure 13B shown, there is a circular hole 1303 at the bottom of the first cavity 1112 for arranging the actuator. Through the hole 1303, the actuator can be connected to the drive shaft 1118 to drive the drive shaft 1118 to rotate.
[0141] Figure 14A is Figure 11B a perspective view of the drive shaft 1118 shown looking down from above at an angle; Figure 14B is Figure 11B a perspective view of the drive shaft shown looking up from below at another angle. As Figure 14A and 14B shown, the drive shaft 1118 includes a shaft rod 1401. The upper end 1410 of the shaft rod 1401 is designed to be able to match the concave portion 1394 in the housing main body 1202, so that the shaft rod 1401 can be rotatably connected to the housing 1101. The lower end 1412 of the shaft rod 1401 is designed to be able to match the output end of the actuator, so that when the actuator operates, it can drive the drive shaft 1118 to rotate.
[0142] The valve 1100 further includes a first clutchable drive structure 1402, a second clutchable drive structure 1403, and a third clutchable drive structure 1404 disposed on the shaft 1401. Specifically, the first clutchable drive structure 1402 is disposed on the upper portion of the shaft 1401. The first clutchable drive structure 1402 includes a first transverse plate 1422 and a plurality of first rods 1424, 1426, 1428. The first transverse plate 1422 is generally fan-shaped and is horizontally disposed on the upper portion of the shaft 1401 such that the circumferential direction of the fan shape is consistent with the circumferential direction of the shaft 1401. The center of the fan shape coincides with the axis of the shaft 1401, so that when the drive shaft 1118 rotates about the first axis X, the plurality of first rods 1424, 1426, 1428 on the first transverse plate 1422 can also rotate about the first axis X. The plurality of first rods 1424, 1426, 1428 are uniformly disposed near the outer edge of the first transverse plate 1422 along the circumferential direction of the first transverse plate 1422 and extend downward from the bottom surface of the first transverse plate 1422. The plurality of first rods 1424, 1426, 1428 are configured to cooperate with a first clutchable driven structure 1555 on the first valve body 1132, so that when the drive shaft 1118 rotates within a first angular range, the first clutchable drive structure 1402 on the drive shaft 1118 (i.e., at least one of the plurality of first rods 1424, 1426, 1428) can drive the first valve body 1132 to rotate together.
[0143] The second clutchable drive structure 1403 includes a second transverse arm 1432 and a second rod 1433. The second transverse arm 1432 is generally elongated and extends perpendicularly from the shaft 1401 in the radial direction of the shaft 1401, so that when the shaft 1401 rotates, the distal end 1436 of the second transverse arm 1432 can also perform a circular motion. The second rod 1433 is disposed at the distal end 1436 of the second transverse arm 1432 and extends upward from the upper surface of the second transverse arm 1432. The second rod 1433 is configured to cooperate with a second clutchable driven structure 1755 on the second valve body 1134, so that when the drive shaft 1118 rotates within a second angular range, the second clutchable drive structure 1403 on the drive shaft 1118 (i.e., the second rod 1433) can drive the second valve body 1134 to rotate together.
[0144] The third clutchable drive structure 1404 includes a third transverse arm 1442 and a third rod 1443. The third transverse arm 1442 is generally elongated and extends perpendicularly from the upper part of the shaft 1401 in the radial direction of the shaft 1401, so that when the shaft 1401 rotates, the distal end 1446 of the third transverse arm 1442 can also perform a circular motion. The third rod 1443 is disposed at the distal end 1446 of the third transverse arm 1442 and extends downward from the lower surface of the third transverse arm 1442. The third rod 1443 is configured to cooperate with the third clutchable driven structure 1955 on the third valve body 1136 and the fourth clutchable driven structure 2155 on the fourth valve body 1138, so that when the drive shaft 1118 rotates within the third angular range, the third clutchable drive structure 1404 (i.e., the third rod 1443) on the drive shaft 1118 can drive the third valve body 1136 to rotate; and when the drive shaft 1118 rotates within the fourth angular range, the third clutchable drive structure 1404 (i.e., the third rod 1443) on the drive shaft 1118 can drive the fourth valve body 1138 to rotate.
[0145] Figure 15A is Figure 11B a perspective view of the first valve body 1132 shown looking down from above; Figure 15B is Figure 11B a perspective view of the first valve body 1132 shown looking up from below. As Figure 15A and 15B shown, the first valve body 1132 is generally a sphere cut vertically up and down, and it has a rotating shaft 1162. A concave portion 1552 is provided at the lower part of the rotating shaft 1162, thereby forming a sleeve 1155. The sleeve 1155 is used to receive the upper end of the rotating shaft 1164 of the second valve body 1134, so that the first valve body 1132 and the second valve body 1134 can rotate about the same first axis X. The upper part 1402 of the first valve body 1132 is designed to match the concave portion 1393 of the second transverse partition plate 1323, so that the upper part 1402 of the first valve body 1132 can be received by the concave portion 1393.
[0146] A first detachable driven structure 1555 is provided on the sphere of the first valve body 1132. The first detachable driven structure 1555 includes a plurality of first grooves 1512, 1513, 1514, 1515, 1516, 1517. The plurality of first grooves 1512, 1513, 1514, 1515, 1516, 1517 are provided on the upper surface of the sphere of the first valve body 1132 and are arranged along the circumference of the first valve body 1132. Specifically, the plurality of first grooves 1512, 1513, 1514, 1515, 1516, 1517 are formed by slotting from the edge of the sphere of the first valve body 1132 to the inside of the sphere, and the distribution of the plurality of first grooves 1512, 1513, 1514, 1515, 1516, 1517 on the sphere of the first valve body 1132 forms a central angle β.
[0147] The first valve body 1132 is provided with two valve body opening portions 1562, 1564, and the two valve body opening portions 1562, 1564 are configured so that when the first valve body 1132 rotates, at least one of the two valve body opening portions 1562, 1564 can selectively align with the first shell opening 1361 and / or the second shell opening 1362 on the cavity wall of the first cavity 1112, thereby respectively realizing the flow and disconnection of the first shell opening 1361 and the second shell opening 1362.
[0148] Figure 16 1 is a schematic diagram of the matching relationship between the first valve body 1132 and the drive shaft 1118, which exemplarily shows one state in which the first detachable driving structure 1402 is engaged with the first detachable driven structure 1555. Figure 16 As shown, when the drive shaft 1118 rotates within the first angle range, at least one of the plurality of first rods 1424, 1426, 1428 on the drive shaft 1118 can engage with at least one of the plurality of first grooves 1512, 1513, 1514, 1515, 1516, 1517. Thus, the drive shaft 1118 can drive the first valve body 1132 to rotate.
[0149] It should be noted that, although the first valve body 1132 is sleeved on the second valve body 1134 , due to the friction between the first valve body 1132 and the second valve body 1134 , when the first valve body 1132 rotates, the second valve body 1134 does not rotate with the first valve body 1132 .
[0150] Figure 17A yes Figure 11B A perspective view of the second valve body 1134 as viewed from top to bottom is shown; Figure 17B yes Figure 11B The second valve body 1134 is shown in a three-dimensional view from bottom to top. Figure 17A and 17BAs shown, the second valve body 1134 includes a second valve body 1733 and a rotating shaft 1164. The top of the rotating shaft 1164 is stepped and can be received by the sleeve 1155 at the bottom of the first valve body 1132, so that the first valve body 1132 and the second valve body 1134 can rotate around the same first axis X.
[0151] The second valve body 1733 is generally a spherical shell cut at the top and bottom, and the second valve body 1733 is arranged around the rotating shaft 1164. The lower part of the second valve body 1733 is fixedly connected to the rotating shaft 1164 through a plurality of connecting columns 1704, 1706, and 1708. A valve body opening portion 1762 is provided on the second valve body 1733, and the valve body opening portion 1762 is configured so that when the second valve body 1134 rotates, the valve body opening portion 1762 can selectively align with the third shell opening 1363 and / or the sixth shell opening 1366 on the cavity wall of the first cavity 1112, thereby realizing the flow and disconnection of the third shell opening 1363 and the sixth shell opening 1366.
[0152] A second detachable driven structure 1755 is provided at the lower portion of the rotating shaft 1164. The second detachable driven structure 1755 includes a second valve body plate 1712. One end of the second valve body plate 1712 is connected to the lower portion of the rotating shaft 1164, and a second groove 1722 is provided on the other end of the second valve body plate 1712. The second groove 1722 is arranged along the radial direction of the second valve body 1134. When the driving shaft 1118 rotates within the second angle range, the second rod 1433 on the driving shaft 1118 can engage with the second groove 1722 on the second valve body 1134.
[0153] Figure 18 1 is a schematic diagram of the matching relationship between the second valve body 1134 and the drive shaft 1118, which exemplarily shows one state of the second detachable driving structure 1403 and the second detachable driven structure 1755 being engaged. Figure 18 As shown, when the driving shaft 1118 rotates within the second angle range, the second rod 1433 on the driving shaft 1118 engages with the second groove 1722. Thus, the driving shaft 1118 can drive the second valve body 1134 to rotate within the second angle range.
[0154] It should be noted that although the first valve body 1132 is sleeved on the second valve body 1134 , due to the friction between the first valve body 1132 and the second valve body 1134 , when the second valve body 1134 rotates, the first valve body 1132 does not rotate with the rotation of the second valve body 1134 .
[0155] Figure 19A yes Figure 11B The third valve body 1136 is shown as a three-dimensional view from a top down angle; Figure 19B yesFigure 11B A perspective view of the third valve body 1136 shown looking up from below from another angle. As Figure 19A and 19B shown, the third valve body 1136 includes a third valve body main body 1933 and a rotating shaft 1166. The top of the rotating shaft 1166 is received by a connecting portion on the pump, and a recess 1902 is provided in the lower portion of the rotating shaft 1166, thereby forming a sleeve 1156. The sleeve 1156 is used to receive the upper end of the rotating shaft 1168 of the fourth valve body 1138, so that the third valve body 1136 and the fourth valve body 1138 can rotate about the same second axis Y.
[0156] The third valve body main body 1933 is generally spherical shell-shaped and is arranged around the rotating shaft 1166. The lower portion of the third valve body main body 1933 is fixedly connected to the rotating shaft 1166 through a connecting plate 1904. Two valve body opening portions 1962, 1964 are provided on the third valve body main body 1933, and the two valve body opening portions 1962, 1964 are configured such that when the third valve body 1136 rotates, at least one of the two valve body opening portions 1962, 1964 can selectively align with the pump outlet housing opening 1369, the seventh housing opening 1367, and / or the eighth housing opening 1368 on the wall of the second cavity 1114, thereby realizing the circulation and disconnection of the pump outlet housing opening 1369, the seventh housing opening 1367, and the eighth housing opening 1368.
[0157] A third separable driven structure 1955 is provided in the lower portion of the rotating shaft 1166. The third separable driven structure 1955 includes a third valve body plate 1912. One end of the third valve body plate 1912 is connected to the lower portion of the rotating shaft 1166, and a third groove 1922 is provided at the other end of the third valve body plate 1912. The third groove 1922 is arranged along the radial direction of the third valve body 1136. When the drive shaft 1118 rotates within a third angular range, the third rod 1443 on the drive shaft 1118 can engage with the third groove 1922 on the third valve body 1136.
[0158] Figure 20 is a schematic diagram of the cooperation relationship between the third valve body 1136 and the drive shaft 1118, exemplarily showing one state in which the third separable driving structure 1404 engages with the third separable driven structure 1955. As Figure 20 shown, when the drive shaft 1118 rotates within a third angular range, the third rod 1443 on the drive shaft 1118 engages with the third groove 1922 on the third valve body 1136. Thus, the drive shaft 1118 can drive the third valve body 1136 to rotate within the third angular range.
[0159] It should be noted that although the third valve body 1136 is sleeved on the fourth valve body 1138, due to the frictional force between the third valve body 1136 and the fourth valve body 1138, when the third valve body 1136 rotates, the fourth valve body 1138 does not rotate with the rotation of the second valve body 1134.
[0160] Figure 21A Is Figure 11B A perspective view of the fourth valve body 1138 shown looking down from above at an angle; Figure 21B Is Figure 11B A perspective view of the fourth valve body 1138 shown looking up from below at another angle. As Figure 21A And 21B Shown, the fourth valve body 1138 includes a fourth valve body main body 2133 and a rotating shaft 1168. The top of the rotating shaft 1166 is stepped and can be received by the sleeve 1156 at the lower part of the third valve body 1136, so that the third valve body 1136 and the fourth valve body 1138 can rotate around the same second axis Y.
[0161] The fourth valve body main body 2133 is generally spherical shell-shaped and is arranged around the rotating shaft 1168. Connecting plates 2104 and 2105 are respectively provided at the upper and lower parts of the fourth valve body main body 2133 and are fixedly connected to the rotating shaft 1168. Three valve body opening parts 2162, 2164, and 2166 are provided on the fourth valve body main body 2133. The three valve body opening parts 2162, 2164, and 2166 are configured such that when the fourth valve body 1138 rotates, at least one of the three valve body opening parts 2162, 2164, and 2166 can selectively align with the fourth housing opening 1364 on the cavity wall of the first cavity 1112, so as to realize the circulation and disconnection of the fourth housing opening 1364.
[0162] The upper part of the rotating shaft 1168 is provided with a fourth separable driven structure 2155. The fourth separable driven structure 2155 includes a fourth valve body plate 2112. One end of the fourth valve body plate 2112 is connected to the upper part of the rotating shaft 1168, and a fourth groove 2122 is provided at the other end of the fourth valve body plate 2112. The fourth groove 2122 is arranged along the radial direction of the fourth valve body 1138. When the drive shaft 1118 rotates within the fourth angle range, the third rod 1443 on the drive shaft 1118 can engage with the fourth groove 2122 on the fourth valve body 1138.
[0163] Figure 22 Is a schematic diagram of the cooperation relationship between the fourth valve body 1138 and the drive shaft 1118, exemplarily showing one state in which the third separable drive structure 1404 and the fourth separable driven structure 2155 are engaged. As Figure 22As shown, when the drive shaft 1118 rotates within the fourth angular range, the third rod 1443 on the drive shaft 1118 engages with the fourth groove 2122. Thus, the drive shaft 1118 can drive the fourth valve body 1138 to rotate within the fourth angular range.
[0164] It should be noted that although the fourth valve body 1138 is sleeved on the fourth valve body 1138, due to the frictional force between the third valve body 1136 and the fourth valve body 1138, when the fourth valve body 1138 rotates, the third valve body 1136 does not rotate along with the rotation of the fourth valve body 1138.
[0165] It should also be noted that in the embodiments of the present application, the third clutchable driven structure 1955 and the fourth clutchable driven structure 2155 respectively cooperate with the third clutchable driving structure 1404 to form a third clutch structure and a fourth clutch structure. However, due to the different lengths of the groove walls on both sides of the third groove 1922 and the groove walls at both ends of the fourth groove 2122, the engagement and separation times of the third clutch structure and the fourth clutch structure are also different. In the embodiments of the present application, when the drive shaft 1118 rotates within the third angular range, the third clutch structure can be engaged, and when the drive shaft 1118 rotates within the fourth angular range, the fourth clutch structure can be engaged.
[0166] Since the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure in the present application generally use the method of grooves and rods to achieve clutch and separation, therefore, in order to clearly illustrate the specific cooperation relationship in the clutch structure, the third clutch structure is taken as an example in the present application for detailed explanation.
[0167] Figure 23A - 23H is a schematic diagram of the third clutch structure during operation, used to show how the third clutch structure achieves engagement and separation. Specifically, the third clutch structure includes a third clutchable driving structure 1404 and a third clutchable driven structure 1955. When the drive shaft 118 rotates within the third angular range, the third clutchable driving structure 1404 can engage with the third clutchable driven structure 1955, thereby driving the third clutchable driven structure 1955 to rotate together; when the drive shaft 1118 rotates outside the third angular range, the third clutchable driving structure 1404 is separated from the third clutchable driven structure 1955, so as not to drive the third clutchable driven structure 1955 to rotate. Figure 23A - 23H The relative positional relationship between the shaft rod 1401, the third transverse arm 1442, and the third rod 1443 of the drive shaft 1118 is schematically shown. When the drive shaft 1118 rotates, the shaft rod 1401, the third transverse arm 1442, and the third rod 1443 rotate together around the third axis Z. Figure 23A - 23HThe relative positional relationship among the rotating shaft 1166 of the third valve body 1136, the third valve body plate 1912, and the third groove 1922 is also schematically shown. When the third valve body 1136 rotates, the rotating shaft 1166, the third valve body plate 1912, and the third groove 1922 rotate together about the second axis Y.
[0168] Figure 23A The relative positional relationship between the third clutchable driving structure 1404 and the third clutchable driven structure 1955 is shown when the drive shaft 1118 has not yet reached the initial angle of the third angular range. Specifically, the actuator drives the drive shaft 1118 to rotate counterclockwise (e.g., in the direction of arrow T in Figure 23A ), so the third clutchable driving structure 1404 also rotates counterclockwise. Since the third clutchable driven structure 1955 is not driven by the actuator, it stays at the first position.
[0169] Figure 23B The relative positional relationship between the third clutchable driving structure 1404 and the third clutchable driven structure 1955 is shown when the drive shaft 1118 reaches the first boundary angle of the third angular range. Specifically, when the drive shaft 1118 rotates counterclockwise to the initial angle of the third angular range, the third rod 1443 of the drive shaft 1118 contacts the first side wall 2302 of the third groove 1922, so the third rod 1443 is received in the third groove 1922.
[0170] Figure 23C The relative positional relationship between the third clutchable driving structure 1404 and the third clutchable driven structure 1955 is shown when the drive shaft 1118 rotates counterclockwise within the third angular range. Specifically, when the drive shaft 1118 continues to rotate counterclockwise, the third rod 1443 pushes the first side wall 2302 of the third groove 1922, thereby causing the third valve body plate 1912 to rotate. Thus, the third clutchable driving structure 1404 drives the third clutchable driven structure 1955 to rotate clockwise (e.g., in the direction of arrow U in Figure 23C ).
[0171] Figure 23D The third clutchable driving structure 1404 is separated from the third clutchable driven structure 1955 when the drive shaft 1118 reaches the second boundary angle of the third angular range. Figure 23EIt shows that when the drive shaft 1118 rotates beyond the third angular range, the third clutchable drive structure 1404 is separated from the third clutchable driven structure 1955. Specifically, when the drive shaft 1118 continues to rotate counterclockwise, the third rod 1443 disengages from the third groove 1922, so that while the drive shaft 1118 continues to rotate counterclockwise, the third clutchable driven structure 1955 remains in the second position. That is to say, at this time, the third clutchable drive structure 1404 cannot drive the third clutchable driven structure 1955 to rotate.
[0172] Figure 23F It shows the relative position relationship between the third clutchable drive structure 1404 and the third clutchable driven structure 1955 when the drive shaft 1118 rotates to the second boundary angle of the third angular range. Specifically, when the drive shaft 1118 rotates in the clockwise direction (for example, in the direction of arrow P as shown in Figure 23F ), the third clutchable drive structure 1404 also rotates in the clockwise direction. The third rod 1443 of the drive shaft 1118 contacts the second side wall 2304 of the third groove 1922, so the third rod 1443 is received in the third groove 1922.
[0173] Figure 23G It shows the relative position relationship between the third clutchable drive structure 1404 and the third clutchable driven structure 1955 when the drive shaft 1118 rotates clockwise within the third angular range. Specifically, when the drive shaft 1118 continues to rotate in the clockwise direction, the third rod 1443 pushes the second side wall 2304 of the third groove 1922, so that the third valve body plate 1912 rotates. Thus, the third clutchable drive structure 1404 drives the third clutchable driven structure 1955 to rotate in the counterclockwise direction (for example, in the direction of arrow V as shown in Figure 23G ).
[0174] Figure 23H It shows that when the drive shaft 1118 rotates to the first boundary angle of the third angular range, the third clutchable drive structure 1404 is separated from the third clutchable driven structure 1955. Specifically, when the drive shaft 1118 continues to rotate in the clockwise direction, the third rod 1443 disengages from the third groove 1922, so that while the drive shaft 1118 continues to rotate clockwise or counterclockwise, the third clutchable driven structure 1955 remains in the first position. That is to say, at this time, the third clutchable drive structure 1404 cannot drive the third clutchable driven structure 1955 to rotate.
[0175] It should be noted that the angle at which the rotation of the third clutchable drive structure 1404 can engage with the third clutchable driven structure 1955 to drive the third clutchable driven structure 1955 to rotate is called the third angular range.
[0176] Continue to refer to Figure 14A - 14B As can be seen from the figure, the first clutchable drive structure 1402, the second clutchable drive structure 1403, and the third clutchable drive structure 1404 provided on the shaft rod 1401 are arranged along different angular directions of the shaft rod 1401. Such an arrangement enables the clutchable drive structures on the shaft rod 1401 to selectively engage with the clutchable driven structures on the valve body when the shaft rod 1401 rotates by different angles, thereby driving the rotation of different valve bodies.
[0177] In the present application, the specific structures and positional relationships of the first valve body 1132, the second valve body 1134, the third valve body 1136, the fourth valve body 1138, as well as the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure are configured to be able to achieve: the valve body opening portion on the first valve body 1132 can cooperate with the first housing opening 1361 and the second housing opening 1362, so that the valve body opening portion on the first valve body 1132 can selectively open at least one of the first housing opening 1361 and the second housing opening 1362; the valve body opening portion on the second valve body 1134 can cooperate with the third housing opening 1363 and the sixth housing opening 1366, so that the valve body opening portion on the second valve body 1134 can selectively open at least one of the third housing opening 1363 and the sixth housing opening 1366; the valve body opening portion on the third valve body 1136 can cooperate with the seventh housing opening 1367 and the eighth housing opening 1368, so that the valve body opening portion on the third valve body 1136 can selectively open at least one of the seventh housing opening 1367 and the eighth housing opening 1368; the valve body opening portion on the fourth valve body 1138 can cooperate with the fifth housing opening 1365, so that the valve body opening portion on the fourth valve body 1138 can selectively open the fifth housing opening 1365.
[0178] When the drive shaft 1118 rotates, one or more of the first valve body 1132, the second valve body 1134, the third valve body 1136, and the fourth valve body 1138 can be selectively rotated, thereby forming different fluid channels inside the valve 1100. As an example, the valve 1100 can achieve various communication relationships as shown in Table 1.
[0179]
[0180] Table 1
[0181] The left serial numbers 1-10 in Table 1 indicate that the drive shaft 1118 rotates by different angles. For example, serial number 1 indicates that the drive shaft 1118 rotates at a first angle. It should be noted that, as an example, serial numbers 1-10 indicate the angles by which the drive shaft 1118 rotates from an initial angle in the same direction. It should also be noted that the drive shaft 1118 is configured to be able to rotate bidirectionally (i.e., clockwise rotation and counterclockwise rotation).
[0182] The symbol "O" in Table 1 indicates that the communication port is in a fully connected state, that is, the housing opening on the housing is aligned with the opening on the valve body, so that the fluid can flow through the entire area of the housing opening on the housing. The symbol "R" in Table 1 indicates that the communication port is in a partially connected state, that is, the housing opening on the housing is partially aligned with the opening on the valve body, so that the fluid can only flow through the part where the housing opening is aligned with the valve body opening. The symbol "×" in Table 1 indicates that the housing opening is in a disconnected state, that is, the housing opening is blocked by the valve body main body, so that the fluid cannot flow through this housing opening. It should be noted that "connection" in the present application includes a fully connected state and a partially connected state.
[0183] By controlling the opening and closing states of each housing opening and the mutual cooperation between each valve body, several fluid channels can be formed in the valve 1100. Each fluid channel is used to connect two corresponding housing openings, so that the external pipelines connected to these two corresponding housing openings can be connected through this fluid channel. The several fluid channels in the valve 1100 can be turned on or off by controlling the rotation of each valve body. For example, if the fourth housing opening 1364 listed in Table 1 is used as the fluid inlet of the valve 1100, and the remaining seven housing openings are used as the fluid outlets of the valve 1100, then there are seven fluid channels in the valve 1100, including fluid channel 1, fluid channel 2, fluid channel 3, fluid channel 5, fluid channel 6, fluid channel 7, and fluid channel 8. Among them, fluid channel 1 connects the fourth housing opening 1364 and the first housing opening 1361, fluid channel 2 connects the fourth housing opening 1364 and the second housing opening 1362, fluid channel 3 connects the fourth housing opening 1364 and the third housing opening 1363, fluid channel 5 connects the fourth housing opening 1364 and the fifth housing opening 1365, fluid channel 6 connects the fourth housing opening 1364 and the sixth housing opening 1366, fluid channel 7 connects the fourth housing opening 1364 and the seventh housing opening 1367, and fluid channel 8 connects the fourth housing opening 1364 and the eighth housing opening 1368.
[0184] When the valve 1100 is at the first angle, the valve body opening portion on the first valve body 1132 is aligned with the fourth housing opening 1364, such that the first housing opening 151 is opened; the valve body opening portion on the first valve body 1132 is aligned with the second housing opening 1362, such that the second housing opening 1362 is opened; the valve body opening portion on the second valve body 1134 is aligned with the third housing opening 1363, such that the third housing opening 1363 is opened; the valve body opening portion on the fourth valve body 1138 is aligned with the fifth housing opening 1365, such that the fifth housing opening 1365 is opened; the valve body opening portion on the third valve body 1136 is aligned with the seventh housing opening 1367, such that the seventh housing opening 1367 is opened; the valve body opening portion on the third valve body 1136 is aligned with the eighth housing opening 1368, such that the eighth housing opening 1368 is opened; while the valve body opening portion on the second valve body 1134 is not aligned with the sixth housing opening 1366, such that the sixth housing opening 1366 is closed or blocked. At this time, the fluid passage 1 connecting the fourth housing opening 1364 and the first housing opening 1361 is connected, the fluid passage 2 connecting the fourth housing opening 1364 and the second housing opening 1362 is connected, the fluid passage 3 connecting the fourth housing opening 1364 and the third housing opening 1363 is connected, the fluid passage 5 connecting the fourth housing opening 1364 and the fifth housing opening 1365 is connected, the fluid passage 7 connecting the fourth housing opening 1364 and the seventh housing opening 1367 is connected, the fluid passage 8 connecting the fourth housing opening 1364 and the eighth housing opening 1368 is connected, while the fluid passage 6 connecting the fourth housing opening 1364 and the sixth housing opening 1366 is disconnected.
[0185] When the valve 1100 is at the second angle, the valve body opening portion on the first valve body 1132 is aligned with the fourth housing opening 1364, so that the first housing opening 151 is opened; the valve body opening portion on the first valve body 1132 is aligned with the second housing opening 1362, so that the second housing opening 1362 is opened; the valve body opening portion on the second valve body 1134 is aligned with the third housing opening 1363, so that the third housing opening 1363 is opened; the valve body opening portion on the fourth valve body 1138 is aligned with the fifth housing opening 1365, so that the fifth housing opening 1365 is opened; the valve body opening portion on the second valve body 1134 is aligned with the sixth housing opening 1366, so that the sixth housing opening 1366 is opened; the valve body opening portion on the third valve body 1136 is aligned with the seventh housing opening 1367, so that the seventh housing opening 1367 is opened; the valve body opening portion on the third valve body 1136 is aligned with the eighth housing opening 1368, so that the eighth housing opening 1368 is opened. At this time, the fluid passage 1 connecting the fourth housing opening 1364 and the first housing opening 1361 is connected, the fluid passage 2 connecting the fourth housing opening 1364 and the second housing opening 1362 is connected, the fluid passage 3 connecting the fourth housing opening 1364 and the third housing opening 1363 is connected, the fluid passage 5 connecting the fourth housing opening 1364 and the fifth housing opening 1365 is connected, the fluid passage 6 connecting the fourth housing opening 1364 and the sixth housing opening 1366 is connected, the fluid passage 7 connecting the fourth housing opening 1364 and the seventh housing opening 1367 is connected, and the fluid passage 8 connecting the fourth housing opening 1364 and the eighth housing opening 1368 is connected.
[0186] Similarly, when the valve 1100 is at the third to tenth angles, the on and off states of the respective fluid passages in the valve 1100 can be obtained according to Table 1.
[0187] It should be noted that Figure 11A - Figure 24 The valve 1100 in the illustrated embodiment is not limited to the above applications. According to the needs of the cooling path of the cooling system, various different fluid passages can be formed in the valve 1100 by configuring power devices such as pumps, so as to use the valve 1100 as a switching device for the cooling path to achieve the purpose of switching the cooling path.
[0188] Although the slot and the rod are used as an example to describe the clutch structure in the present application, those skilled in the art can understand that according to the spirit of the present application, other cooperation methods for realizing such clutch and separation (such as a clamping device, gear meshing) are also within the protection scope of the present application.
[0189] The valve 1100 of the present application can achieve different channel switches of the fluid through the openings on the valve body and the housing openings on the housing, and can also control the flow rate of each channel. Such a setting enables the control components in the system to control fewer components to achieve different channel switches of the fluid, while enhancing the stability of the system control during integrated control.
[0190] To ensure the sealing performance between the housing opening and the valve body when each housing opening in the valve 1100 is not aligned with the opening on the valve body (i.e., the housing opening is closed), the valve 1100 further includes a first set of seals and a second set of seals. Each of the first set of seals is disposed between the first valve body 1132, the second valve body 1134, the fourth valve body 1138 and each of the first set of housing openings. Each of the first set of seals is configured to be able to resist against the cavity wall where each of the first set of housing openings is located, so that when the valve body rotates, the first set of seals can abut against the cavity wall and does not rotate with the rotation of the valve body. The second set of seals includes two seals, one of the two seals is disposed between the seventh housing opening 1367 and the third valve body 1136, and the other of the two seals is disposed between the eighth housing opening 1368 and the third valve body 1136. Since the pump outlet housing opening 1369 in the second set of housing openings is connected to the outlet of the pump, no sealing ring is provided.
[0191] When the valve body rotates, due to the friction between the valve body and the seal, the actuator driving the valve body to rotate requires a large driving force to drive the valve body to rotate so as to overcome the friction between the valve body and the seal. When a traditional valve drives one or more valve bodies to rotate, the drive shaft of the valve needs to overcome the friction brought by all the seals provided in the valve body, so that the required power of the actuator is relatively large.
[0192] The valve 1100 in the present application also has the following advantages: when the channels that need to flow in the valve 1100 can be achieved by rotating the valve body on one side of the drive shaft 1118, since the valve body on the other side does not rotate, there will be no friction between the non-rotating valve body and the seal, thereby reducing the driving force provided by the actuator, and only the friction that the valve body that needs to rotate on the drive shaft 1118 needs to overcome needs to be provided. The following takes the state of the valve body in the valve 1100 at serial numbers 8-10 in Table 1 as an example for introduction.
[0193] Figure 24 is Figure 11A A schematic diagram of the valve 1100 shown in which the first housing opening 1361 and the second housing opening 1362 are cut along the horizontal direction, Figure 24Shown therein are a first seal 2402 disposed between the first valve body 1132 and the first housing opening 1361, a second seal 2404 disposed between the first valve body 1132 and the second housing opening 1362, and a third seal 2406 disposed between the fourth valve body 1138 and the fifth housing opening 1365. When the drive shaft 1118 rotates within the angular range shown in Numbers 8 - 10, only the first valve body 1132 and the second valve body 1134 need to be rotated. Therefore, the actuator that drives the drive shaft 1118 to rotate only needs to provide a force that can overcome the frictional force of the seals on the first valve body 1132 and the second valve body 1134.
[0194] It should be noted that, in Figure 1A - Figure 24 each of the embodiments shown, the valve body opening portion on each valve body forms a valve body acting portion, which is used to cooperate with a corresponding one of several housing openings when the driven valve body component rotates a predetermined angle, so as to selectively connect at least one fluid passage. In other embodiments, the valve body acting portion may also be a valve body blocking portion, which is used to cooperate with at least one of several housing openings when the driven valve body component rotates a predetermined angle, so that the valve body blocking portion selectively blocks at least one of several housing openings, thereby selectively disconnecting at least one fluid passage. The following takes Figure 25A - 25C as an example for description:
[0195] Figure 25A is a side perspective structural schematic diagram of the ninth embodiment of the valve according to the present application; Figure 25B is Figure 25A The valve 2500 shown in Figure 25A is a cross-sectional view along the center line H - H, Figure 25C is Figure 25A The valve 2500 shown in Figure 25A is a cross-sectional view along the center line I - I to show another embodiment of the acting portion of the valve body component. As Figure 25A - 25C shown, the valve 2500 includes a housing 2501. The housing 2501 is generally cylindrical and has a housing cavity 2502 therein. Four housing openings are provided on the housing 2501, namely a first housing opening 2551, a second housing opening 2552, a third housing opening 2553, and a fourth housing opening 2554. The housing cavity 2502 can be in fluid communication with the outside of the valve 2500 through any one of the first housing opening 2551, the second housing opening 2552, the third housing opening 2553, and the fourth housing opening 2554. The first housing opening 2551 and the second housing opening 2552 are arranged at the same height on the left and right sides of the housing 2501, and the third housing opening 2553 and the fourth housing opening 2554 are arranged at the same height on the front and back sides of the housing 2501 with respect to the housing 2501.
[0196] The valve 2500 further includes a driving device 2580. The driving device 2580 includes an actuator 2590 and a driving shaft 2518. The actuator 2590 is disposed outside the housing 2501. The driving shaft 2518 is disposed in the housing 2501 along the height direction and is connected to the actuator 2590. The actuator 2590 is capable of driving the driving shaft 118 to rotate.
[0197] The valve 2500 further includes a first valve body 121 and a second valve body 122. The first valve body 121, the first housing opening 151, and the second housing opening 152 are arranged at substantially the same height. The second valve body 122, the third housing opening 153, and the fourth housing opening 154 are arranged at substantially the same height. The first valve body 121 and the second valve body 122 are generally rectangular bodies, and their waists are concave portions, so that a clearance cavity 2588 is formed between the first valve body 121 and the housing 2501, and a clearance cavity 2589 is formed between the second valve body 122 and the housing 2501.
[0198] The valve 2500 further includes seals 2571, 2572, 2573, 2574. The seals 2571, 2572, 2573, 2574 are respectively disposed inside the housing 2501 and respectively surround the housing openings 2551, 2552, 2553, 2554 for sealing the gaps between the several housing openings 2551, 2552, 2553, 2554 and the corresponding one of the several valve bodies 2521, 2522, 2523, 2524.
[0199] The valve 2500 further includes a first clutch structure 2541 and a second clutch structure 2542. The first clutch structure 2541 includes a first separable driving structure 2581 and a first separable driven structure 2591. The first separable driving structure 2581 is disposed on the driving shaft 2518. The first separable driven structure 2591 is disposed on the first valve body 2521. The first separable driving structure 2581 and the first separable driven structure 2591 are configured to be able to cooperate with each other so that when the driving shaft 2518 rotates within a first angular range, the first separable driving structure 2581 on the driving shaft 2518 can drive the first valve body 2521 to rotate. The second clutch structure 142 includes a second separable driving structure 2582 and a second separable driven structure 2592. The second separable driving structure 2582 is disposed on the driving shaft 2518. The second separable driven structure 2592 is disposed on the second valve body 2522. The second separable driving structure 2582 and the second separable driven structure 2592 are configured to be able to cooperate with each other so that when the driving shaft 2518 rotates within a second angular range, the second separable driving structure 2582 on the driving shaft 2518 can drive the second valve body 2522 to rotate.
[0200] As an example, Figure 25A - 25C The clutch structure in Figure 25A - 25C is a clamping device. The clutchable driven structure is arranged around the clutchable driving structure. When the clutchable driven structure clamps the clutchable driving structure, the clutchable driving structure can drive the clutchable driven structure to rotate. When the clutchable driven structure does not clamp the clutchable driving structure, the clutchable driving structure cannot drive the clutchable driven structure to rotate.
[0201] Figure 25B The state shown is that the first clutchable driven structure 2591 clamps the first clutchable driving structure 2581. At this time, the first valve body 2521 blocks the first housing opening 2551 and the second housing opening 2552, so that the first housing opening 2551 and the second housing opening 2552 cannot be in fluid communication with the housing cavity 2502. In other words, the first housing opening 2551 and the second housing opening 2552 are disconnected.
[0202] Figure 25C The state shown is that the second clutchable driven structure 2592 does not clamp the second clutchable driving structure 2582. At this time, the second valve body 2522 does not block the third housing opening 2553 and the fourth housing opening 2554. The third housing opening 2553 and the fourth housing opening 2554 can communicate with each other through the clearance cavity 2589 (that is, bypass the second valve body 2522).
[0203] Thus, it can be seen that Figures 25A - 25C In the valve 2500 shown, the acting part of the valve body component is the valve body itself (that is, the blocked part of the valve body). When the blocked part of the valve body cooperates with the housing opening, the valve body component can block the housing opening, thereby disconnecting the fluid passage and forming a fluid passage between the housing openings not blocked by the blocked part of the valve body.
[0204] It should be noted that Figures 1A - 10 The embodiment shown can also adopt Figures 25A - 25C The blocked part of the valve body shown to implement the opening and blocking operations of the housing opening, so as to selectively connect or disconnect at least one of several fluid passages in the valve through the driven valve body.
[0205] Although only some features of the present application are illustrated and described herein, various improvements and changes can be made by those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all the above improvements and changes falling within the spirit of the present application.
