[0049] Currently, with the integration of heat exchange systems in automobiles, such as motor cooling, battery heating and cooling, and passenger compartment heating, the functional requirements for control valves in these systems are becoming increasingly demanding. Currently, automotive heat exchange systems typically use two three-way valves and one four-way valve to cool the motor and heat and cool the battery. However, the piping in these systems, connected by two three-way valves and one four-way valve, is complex, requiring simultaneous control of three valves and involving numerous connection points, which increases the risk of leaks.
[0050] To solve the above problems, the present invention provides a control valve 100. Figures 3 to 6 A specific embodiment of the control valve 100 provided by the present invention.
[0051] Please see Figures 1 to 3First, it needs to be explained that the existing automotive heat exchange system 1000 water-medium circuit is divided into two parts: one part is the motor water-medium circuit 200, and the other part is the battery 320 water-medium circuit 300.
[0052] The motor water-cooled circuit 200 includes a motor inlet branch 210, a motor 250, a first motor drain branch 220, a second motor drain branch 230, and a third motor drain branch 240. The motor inlet branch 210 includes a first water tank 211 and a first pump body 212 connected in sequence. The second motor drain branch 230 is at least partially located in the vehicle's plate heat exchanger 231 to exchange heat with the vehicle's refrigerant circuit. The third motor drain branch 240 includes an external water tank 241. Furthermore, the motor water-cooled circuit 200 also includes a first three-way valve 410 and a second three-way valve 420. The first three-way valve 410 has a first valve port 411, and the second three-way valve 420 has a second valve port 421. 411 is interconnected with the second valve port 421. The two valve ports of the first three-way valve 410, excluding the first valve port 411, are respectively connected to the second drainage branch and the third motor drainage branch 240, thereby selecting one of the second drainage branch and the third motor drainage branch 240 to connect to the first valve port 411, and then connecting to the second valve port 421 of the second three-way valve 420. The second three-way valve 420 is also provided with a third valve port 422, which is used for the refrigerant discharged by the motor 250 to flow out. The second three-way valve is also provided with a fourth valve port, which is connected to the first motor drainage branch 220. The second three-way valve is used to select one of the second valve port 421 and the fourth valve port to connect to the third valve port 422.
[0053] In short, the third valve port 422 is the outlet for the water medium of the battery 320. When it is connected to the fourth valve port, the water medium of the motor 250 is discharged from the third valve port 422 via the first motor drainage branch 220 and the second three-way valve 420. When the second motor drainage branch 230 is connected to the first valve port 411 and the second valve port 421 is connected to the third valve port 422, the water medium of the motor 250 is discharged from the third valve port 422 via the second motor drainage branch 230, the first three-way valve 410, and the second three-way valve 420. When the third motor drainage branch 240 is connected to the first valve port 411 and the second valve port 421 is connected to the third valve port 422, the water medium of the motor 250 is discharged from the third valve port 422 via the third motor drainage branch 240, the first three-way valve 410, and the second three-way valve 420. In summary, through the first three-way valve 410 and the second three-way valve 420, the water medium flowing through the motor 250 reaches the third valve port 422 from one of the first motor drainage branch 220, the second motor drainage branch 230, and the third motor drainage branch 240.
[0054] The battery 320 water circuit 300 includes a battery water inlet branch 310, a battery 320, and a battery water outlet branch 330 connected in sequence. The battery water inlet branch 310 includes a second water tank 311, a second pump body 312, a water heater 313, and a battery cooler 314 connected in sequence. The water flows out from the second water tank 311, passes through the second pump body 312, the water heater 313, and the battery cooler 314 in sequence, and is discharged from the battery water outlet branch 330.
[0055] The water-medium circuit of the heat exchange system 1000 also includes a four-way valve 430. The four-way valve 430 is connected to the third valve port 422, the motor water inlet branch 210, the battery water inlet branch 310, and the battery water outlet branch 330. The four-way valve 430 connects one of the motor water inlet branch 210 and the battery water inlet branch 310 to one of the third valve port 422 and the battery water outlet branch 330, and connects the remaining two to each other. Specifically, the third valve port 422 can be connected to the motor water inlet branch 210, and the battery water inlet branch 310 can be connected to the battery water outlet branch 330. In this case, the motor water-medium circuit 200 and the battery water-medium circuit 300 are connected in parallel. Each can operate independently. Alternatively, the third valve port 422 can be connected to the battery water inlet branch 310. In this case, the motor water medium circuit 200 and the battery 320 water medium circuit 300 are connected in series. The water medium flows out from the first water tank 211, passes through the motor 250, and reaches the third valve port 422 from one of the three: the first motor drainage branch 220, the second motor drainage branch 230, and the third motor drainage branch 240. It then flows into the second water tank 311, flows out from the second water tank 311, passes through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330, returning to the first water tank 211 to complete the cycle.
[0056] In the above-mentioned circulation loop, in order to realize different operating modes in the motor water medium circuit 200, a first three-way valve 410 and a second three-way valve 420 are used. In order to realize the series-parallel relationship between the motor water medium circuit 200 and the battery 320 water medium circuit 300, a four-way valve 430 is used. Therefore, a total of two three-way valves and one four-way valve 430 are used. The pipeline connection is relatively complex, and it is necessary to control the switching of three valves at the same time. In addition, there are many interfaces for the pipeline connection of the three valves, which can easily cause leakage.
[0057] Based on this, please refer to Figures 3 to 6This application proposes a control valve 100, which has a first communicating plane 110 and a second communicating plane 120 distributed along a first direction. The control valve 100 includes a housing 130, a first valve body 140, a second valve body 150, and a valve core 160.
[0058] The housing 130 extends along a first direction. The housing 130 has a first connection port 111, a second connection port 112, a third connection port 113 and a first communication port 114 on the first communicating plane 110. It also has a fourth connection port 121, a fifth connection port 122, a sixth connection port 123 and a second communication port 124 on the second communicating plane 120. The first communication port 114 is connected to the second communication port 124.
[0059] Both the first valve body 140 and the second valve body 150 are rotatably mounted within the housing 130 along an axis extending in a first direction. The first valve body 140 is located on the first communicating plane 110 and is used to connect one of the first connecting port 111, the second connecting port 112, and the third connecting port 113 to the first communicating port 114. The second valve body 150 is located on the second communicating plane 120 and is used to connect one of the fourth connecting port 121 and the sixth connecting port 123 to the second communicating port 124, and to connect the other of the fourth connecting port 121 and the sixth connecting port 123 to the fifth communicating port. The valve core 160 is used to drive the first valve body 140 and the second valve body 150 to rotate.
[0060] It should be noted that the first direction is any direction in the plane, which can be forward and backward, up and down, or left and right, without any restrictions.
[0061] The first connecting plane 110 can be regarded as an integration of the first three-way valve 410 and the second three-way valve 420 mentioned above. The first connection port 111, the second connection port 112 and the third connection port 113 are respectively connected to the first motor drainage branch 220, the second motor drainage branch 230 and the third motor drainage branch 240 mentioned above. The first connecting port 114 can be regarded as the third valve port 422 mentioned above. Through the first connecting plane 110, the water medium discharged by the motor 250 can reach the first connecting port 114 via one of the first motor drainage branch 220, the second motor drainage branch 230 and the third motor drainage branch 240, thereby integrating the functions of two three-way valves. It should be emphasized that the branches connected to the first connection port 111, the second connection port 112, and the third connection port 113 are not limited. Alternatively, the first connection port 111, the second connection port 112, and the third connection port 113 can be connected to the second motor drainage branch 230, the third motor drainage branch 240, and the first motor drainage branch 220 mentioned above, respectively. The connection method can be arbitrarily combined.
[0062] The second connecting plane 120 can be considered as the four-way valve 430 mentioned above. The second connecting port 124 is connected to the first connecting port 114, that is, connected to one of the first motor drainage branch 220, the second motor drainage branch 230, and the third motor drainage branch 240. The fourth connecting port 121 is used to connect to one of the battery water inlet branch 310 or the motor water inlet branch 210. The sixth connecting port 123 connects to the other of the battery water inlet branch 310 or the motor water inlet branch 210. The fifth connecting port 122 connects to the battery 320 drainage branch. For ease of understanding, in this embodiment, the fourth connecting port 121 connects to the battery water inlet branch 310, and the sixth connecting port 123 connects to the other of the battery water inlet branch 310. Interface 123 connects to the motor water inlet branch 210. The second valve body 150 is located on the second connecting plane 120, used to connect one of the fourth connection port 121 and the sixth connection port 123 to the second connecting port 124. That is, one of the battery water inlet branch 310 and the motor water inlet branch 210 is connected to the second connecting port 124. When the battery water inlet branch 310 and the second connecting port 124 are connected, the motor water medium circuit 200 and the battery 320 water medium circuit 300 are connected in series. When the motor water inlet branch 210 and the second connecting port 124 are connected, the motor water medium circuit 200 and the battery 320 water medium circuit 300 are connected in parallel.
[0063] In the technical solution provided by the present invention, a six-port control valve 100 is designed to replace the control of two existing three-port valves and one four-port valve 430. The technical solution of the present invention reduces the number of control valves 100 in the heat exchange system 1000 of the automobile, further simplifies the connection of pipelines, avoids leakage problems caused by a large number of valves, and at the same time, the cost of a control valve 100 is relatively low.
[0064] Furthermore, the first valve body 140 and the second valve body 150 can be equipped with different driving devices to drive the first valve body 140 and the second valve body 150 to rotate independently, respectively. This configuration allows for three different parallel circuits and three different series circuits. The three different parallel circuits are as follows:
[0065] The first method involves the water medium in the motor water medium circuit 200 flowing out from the first water tank 211, passing through the first pump body 212, the motor 250, and the first motor drainage branch 220, and returning to the first water tank 211, thus completing the water medium circulation. The water medium in the battery 320 water medium circuit 300 flows out from the second water tank 311, passing through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330 back to the second water tank 311, completing the water medium circulation.
[0066] The second method involves the water medium in the motor water medium circuit 200 flowing out from the first water tank 211, passing through the first pump body 212, the motor 250, and the second motor drainage branch 230, returning to the first water tank 211, thus completing the water medium circulation. The water medium in the battery 320 water medium circuit 300 flows out from the second water tank 311, passing through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330 back to the second water tank 311, completing the water medium circulation.
[0067] The third method: Water from the motor water circuit 200 flows out of the first water tank 211, flows through the first pump body 212, the motor 250 and the third motor drainage branch 240 back to the first water tank 211, thus completing the water circulation. Water from the battery 320 water circuit 300 flows out of the second water tank 311, passes through the second pump body 312, the water heater 313 and the battery cooler 314 in sequence, and is discharged from the battery water outlet branch 330 back to the second water tank 311, thus completing the water circulation.
[0068] The three different series circuits are:
[0069] The first method involves the water medium flowing out of the first kettle 211, passing through the first pump body 212, the motor 250, and the first motor drainage branch 220 to reach the second kettle 311. From the second kettle 311, the water medium flows out sequentially through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330 back to the first kettle 211, thus completing the water medium circulation.
[0070] The second method involves the water medium flowing out of the first water tank 211, passing through the first pump body 212, the motor 250, and the second motor drainage branch 230 to reach the second water tank 311. From the second water tank 311, the water medium flows out through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330 back to the first water tank 211, thus completing the water medium circulation.
[0071] The third method involves the water medium flowing out of the first water tank 211, passing through the first pump body 212, the motor 250, and the third motor drainage branch 240 to reach the second water tank 311. From the second water tank 311, the water medium flows out through the second pump body 312, the water heater 313, and the battery cooler 314, and is discharged from the battery water outlet branch 330 back to the first water tank 211, thus completing the water medium circulation.
[0072] Of course, in order to reduce the number of drive motors 250, only one drive motor 250 is used to achieve synchronous rotation of the first valve body 140 and the second valve body 150. The first valve body 140 and the second valve body 150 are connected as one unit so that the valve core 160 drives the first valve body 140 and the second valve body 150 to rotate synchronously. At this time, only one drive motor 250 is needed to drive the valve core 160 to drive the first valve body 140 and the second valve body 150 to rotate synchronously, thereby realizing the switching of modes.
[0073] Please see Figure 3
[0074] Preferably, in one embodiment, the first connection port 111 is connected to the third motor drainage branch 240, the second connection port 112 is connected to the first motor drainage branch 220, the third connection port 113 is connected to the second motor drainage branch 230, the fourth connection port 121 is connected to the motor water inlet branch 210, the fifth connection port 122 is connected to the battery 320 drainage branch, and the sixth connection port 123 is connected to the battery water inlet branch 310.
[0075] Alternatively, the first connection port 111 connects to the second motor drainage branch 230, the second connection port 112 connects to the first motor drainage branch 220, the third connection port 113 connects to the third motor drainage branch 240, the fourth connection port 121 connects to the motor water inlet branch 210, the fifth connection port 122 connects to the battery 320 drainage branch, and the sixth connection port 123 connects to the battery water inlet branch 310.
[0076] The first valve body 140 and the second valve body 150 together form a valve body structure. Within the rotation stroke of the valve body structure, the valve body structure has a first position, a second position, and a third position.
[0077] When the valve body structure is in the first position, the first connection port 111 is connected to the fourth connection port 121 through the first connecting port 114 and the second connecting port 124, and the fifth connection port 122 is connected to the sixth connection port 123. In the first connection method, the valve body structure enables the water medium circuit of the vehicle's heat exchange system 1000 to have a third parallel circuit state. In the second connection method, the valve body structure enables the water medium circuit of the vehicle's heat exchange system 1000 to have a second parallel circuit state.
[0078] When the valve body structure is in the second position, the second connection port 112 is connected to the sixth connection port 123 through the first connection port 114 and the second connection port 124, and the fifth connection port 122 is connected to the fourth connection port 121; in the first connection method and the second connection method, the valve body structure enables the water medium circuit of the heat exchange system 1000 of the vehicle to have a first series circuit state.
[0079] When the valve body structure is in the third position, the third connection port 113 is connected to the fourth connection port 121 through the first connection port 114 and the second connection port 124, and the fifth connection port 122 is connected to the sixth connection port 123. In the first connection method, the valve body structure allows the water medium circuit of the vehicle's heat exchange system 1000 to have a second parallel circuit state. In the second connection method, the valve body structure allows the water medium circuit of the vehicle's heat exchange system 1000 to have a third parallel circuit state.
[0080] The above two connection methods can achieve the following: the water medium circuit of the vehicle's heat exchange system 1000 has a second parallel circuit state, a third parallel circuit state, and a first series circuit state. Driven by a drive motor 250, the first valve body 140 and the second valve body 150 rotate synchronously and switch between the first position, the second position, and the third position, allowing the water medium circuit of the vehicle's heat exchange system 1000 to switch between the three states.
[0081] In another embodiment, the first connection port 111 is connected to the first motor drainage branch 220, the second connection port 112 is connected to the third motor drainage branch 240, the third connection port 113 is connected to the second motor drainage branch 230, the fourth connection port 121 is connected to the battery water inlet branch 310, the fifth connection port 122 is connected to the battery 320 drainage branch, and the sixth connection port 123 is connected to the motor water inlet branch 210.
[0082] Alternatively, the first connection port 111 connects to the second motor drainage branch 230, the second connection port 112 connects to the third motor drainage branch 240, the third connection port 113 connects to the second motor drainage branch 230, the fourth connection port 121 connects to the battery water inlet branch 310, the fifth connection port 122 connects to the battery 320 drainage branch, and the sixth connection port 123 connects to the motor water inlet branch 210.
[0083] The first valve body 140 and the second valve body 150 together form a valve body structure. Within the rotation stroke of the valve body structure, the valve body structure has a first position, a second position, and a third position.
[0084] When the valve body structure is in the first position, the first connection port 111 is connected to the fourth connection port 121 through the first connecting port 114 and the second connecting port 124, and the fifth connection port 122 is connected to the sixth connection port 123. In the first connection method, the valve body structure enables the water medium circuit of the vehicle's heat exchange system 1000 to have a first series circuit state. In the second connection method, the valve body structure enables the water medium circuit of the vehicle's heat exchange system 1000 to have a second parallel circuit state.
[0085] When the valve body structure is in the second position, the second connection port 112 is connected to the sixth connection port 123 through the first connection port 114 and the second connection port 124, and the fifth connection port 122 is connected to the fourth connection port 121; in the first connection method and the second connection method, the valve body structure enables the water medium circuit of the vehicle's heat exchange system 1000 to have a second parallel circuit state.
[0086] When the valve body structure is in the third position, the third connection port 113 is connected to the fourth connection port 121 through the first connection port 114 and the second connection port 124, and the fifth connection port 122 is connected to the sixth connection port 123. In the first connection method, the valve body structure allows the water medium circuit of the vehicle's heat exchange system 1000 to have a second series circuit state. In the second connection method, the valve body structure allows the water medium circuit of the vehicle's heat exchange system 1000 to have a first series circuit state.
[0087] The above two connection methods can achieve the following: the water medium circuit of the vehicle's heat exchange system 1000 has a second parallel circuit state, a first series circuit state, and a second series circuit state. Under the drive of a drive motor 250, the first valve body 140 and the second valve body 150 rotate synchronously and switch between the first position, the second position, and the third position, so that the water medium circuit of the vehicle's heat exchange system 1000 can switch between the three states.
[0088] There are many ways to enable the first valve body 140 to connect one of the first connection port 111, the second connection port 112, and the third connection port 113 to the first communication port 114. For example, three openable and closable connecting pipes can be set up to connect the first connection port 111, the second connection port 112, and the third connection port 113 to the first communication port 114 respectively. When it is necessary to connect the first connection port 111 to the first communication port 114, the connecting pipe between the two can be opened directly and the other two connecting pipes can be closed. This enables the first valve body 140 to connect one of the first connection port 111, the second connection port 112, and the third connection port 113 to the first communication port 114. Of course, the above method requires the installation of an opening and closing device in the connecting pipe, which has poor stability and is cumbersome to operate and install.
[0089] Therefore, it is also possible that the first valve body 140 includes a first valve pipe 141, the first valve pipe 141 including a first main valve pipe section 142, a first branch valve pipe section 143, a second branch valve pipe section 144, and a third branch valve pipe section 145, which are sequentially arranged and connected along the first circumferential direction of the first valve body 140; the first connecting port 114, the first connecting port 111, the second connecting port 112, and the third connecting port 113 are arranged sequentially along the second circumferential direction of the first valve body 140; the first circumferential direction and the second circumferential direction are two opposite directions; wherein, the included angle between the center of the first main valve pipe section 142 and the first branch valve pipe section 143 is equal to the included angle between the first connecting port 114 and the first connecting port 111, at this time, the first main valve pipe section 142 is connected to the first connecting port 111, and the corresponding first branch valve pipe section 143 is connected to the first connecting port 114; the first main valve pipe section 142 and the second branch valve pipe section 143 are arranged sequentially and connected along the first circumferential direction of the first valve body 140; the first connecting port ... first branch valve pipe section 143 are arranged sequentially and connected along the first circumferential direction of the first valve body 14 The included angle between the centers of the branch valve pipe sections 144 is equal to the included angle between the first connecting port 114 and the second connecting port 112. At this time, the first main valve pipe section 142 is connected to the second connecting port 112, and the corresponding second branch valve pipe section 144 is connected to the first connecting port 114. The included angle between the centers of the first main valve pipe section 142 and the third branch valve pipe section 145 is equal to the included angle between the first connecting port 114 and the third connecting port 113. At this time, the first main valve pipe section 142 is connected to the third connecting port 113, and the corresponding third branch valve pipe section 145 is connected to the first connecting port 114. Thus, when the first main valve pipe section 142 is connected to any one of the connecting ports, there is a corresponding branch valve pipe section connected to the first connecting port 114. This realizes that the first valve body 140 connects one of the first connecting port 111, the second connecting port 112, and the third connecting port 113 to the first connecting port 114.
[0090] Furthermore, the first valve pipe 141 includes a first main valve pipe section 142, a first branch valve pipe section 143, a second branch valve pipe section 144, and a third branch valve pipe section 145, which are arranged sequentially and interconnected along the first circumferential direction of the first valve body 140; the first connecting port 114, the first connecting port 111, the second connecting port 112, and the third connecting port 113 are arranged sequentially along the second circumferential direction of the first valve body 140, and the reverse arrangement between the pipe sections and the connecting ports can effectively prevent the first valve pipe 141 from connecting all of the first connecting port 114, the first connecting port 111, the second connecting port 112, and the third connecting port 113.
[0091] It should be emphasized that in this embodiment, the first connecting port 114, the first connecting port 111, the second connecting port 112, and the third connecting port 113 are not evenly distributed. The central angle between the first connecting port 114 and the first connecting port 111 and the third connecting port 113 is an obtuse angle and an acute angle, respectively.
[0092] Therefore, since it is desired that the first valve pipe 141 rotates three times to achieve three states, and rotates a fourth time to return to the initial state, completing one cycle, in order to facilitate the control of the motor 250 rotation, in this embodiment, the motor 250 only needs to drive the first valve pipe 141 to rotate 90° to switch the corresponding state for the first connection port 111, the second connection port 112, and the third connection port 113. At this time, if the included angle between the first connecting port 114 and the first connection port 111 is a right angle, the first connecting port 114, the first connection port 111, the second connection port 112, and the third connection port 113 will be interconnected regardless of how the first valve pipe 141 rotates. Therefore, the included angle between the center of the first main valve pipe section 142 and the first branch valve pipe section 143 is set to an obtuse angle, thereby effectively preventing the first valve pipe 141 from connecting all the first connecting ports 114, the first connection port 111, the second connection port 112, and the third connection port 113.
[0093] Of course, the included angle between the central angles of the first connection port 111, the second connection port 112 and the third connection port 113 may not be 90°. By controlling the motor 250 to rotate in accordance with the included angle between the three central angles, the switching between the three states can also be realized. No restrictions are imposed here.
[0094] Furthermore, in order to enable the second valve body 150 to connect one of the fourth connection port 121 and the sixth connection port 123 to the second communication port 124, and to connect the other of the fourth connection port 121 and the sixth connection port 123 to the fifth communication port, the fourth connection port 121, the fifth connection port 122, the sixth connection port 123 and the second communication port 124 are arranged at intervals along the circumferential direction of the housing 130; the second valve body 150 includes a second valve tube 151 and a third valve tube 152, both of which are connected to the valve core 160. The valve core 160 can drive the second valve tube 151 and the third valve tube 152 to rotate. The second valve tube 151 is connected to any two adjacent ports among the fourth connection port 121, the fifth connection port 122, the sixth connection port 123 and the second communication port 124. The third valve tube 152 is connected to the remaining two adjacent ports among the fourth connection port 121, the fifth connection port 122, the sixth connection port 123 and the second communication port 124. This enables the second valve body 150 to connect one of the fourth connection port 121 and the sixth connection port 123 to the second communication port 124.
[0095] Of course, the fifth connection port 122 and the second connection port 124 can be interchanged, and / or the fourth connection port 121 and the sixth connection port 123 can be interchanged accordingly, without any limitation.
[0096] It is worth mentioning that the second valve pipe 151 and the third valve pipe 152 are curved. Specifically, the curved design of the second valve pipe 151 and the third valve pipe 152 can reduce the resistance of the liquid in the water circulation through the second valve pipe 151 and the third valve pipe 152, thereby increasing the flow effect of the liquid. Of course, in other embodiments, the second valve pipe 151 and the third valve pipe 152 can also be set as straight pipes, or as right-angle pipes, or as other irregularly shaped pipes, as long as they can serve to connect the two connection ports, no specific limitation is set here.
[0097] Since it is desired that the second valve pipe 151 rotates three times to achieve three states, and rotates a fourth time to return to the initial state, completing one cycle, in order to facilitate the control of the motor 250 rotation, in this embodiment, the center angles between any two adjacent pairs of the fourth connection port 121, the fifth connection port 122, the sixth connection port 123, and the second communication port 124 are equal. This allows the motor 250 to switch between states every 90° of rotation, and to return to the initial state on the fourth rotation.
[0098] In order to enable the heat exchange system 1000 using the control valve 100 of this application to have the six states described above, and to ensure that the rotation of the first valve body 140 and the second valve body 150 does not interfere with each other, in one embodiment, the valve core 160 includes a first valve core 160 and a second valve core 160. The first valve core 160 is connected to the first valve body 140 to drive the first valve body 140 to rotate, and the second valve core 160 is connected to the second valve body 150 to drive the second valve body 150 to rotate. This ensures that the rotation of the first valve body 140 and the second valve body 150 does not interfere with each other, and the heat exchange system 1000 using the control valve 100 of this application can have the six states described above.
[0099] To achieve communication between the first connecting plane 110 and the second connecting plane 120, the housing 130 includes an inner sleeve 131 and an outer sleeve 132, with the first valve body 140 and the second valve body 150 disposed within the inner cavity of the inner sleeve 131. Three first connecting pipes 133 are provided on the first connecting plane 110, with one end of each first connecting pipe 133 connected to the corresponding inner sleeve 131, and the other end of each first connecting pipe 133 extending through the outer sleeve 132 to respectively form the first connecting port 111, the second connecting port 112, and the third connecting port 113. On the second connecting plane 120... Three second connecting pipes 134 are provided. One end of each second connecting pipe 134 is connected to the corresponding inner sleeve 131, and the other end of each second connecting pipe 134 extends out of the outer sleeve 132 to form the fourth connecting port 121, the fifth connecting port 122, and the sixth connecting port 123, respectively. The first connecting port 114 and the second connecting port 124 are both provided in the inner sleeve 131. A connecting structure is formed between the inner sleeve 131 and the outer sleeve 132 to connect the first connecting port 114 and the second connecting port 124, thereby realizing the connection between the first connecting plane 110 and the second connecting plane 120.
[0100] Specifically, the form of the connecting structure can be various. It can be a direct connection using a single connecting pipe, or it can be that two partitions 135 extending axially along the inner sleeve 131 are provided between the inner sleeve 131 and the outer sleeve 132, with the two partitions 135 spaced apart circumferentially along the inner sleeve 131; two sealing caps 170 are also provided at both ends of the housing 130, and the two sealing caps 170 and the two partitions 135 together form a connecting cavity; the connecting structure includes the connecting cavity.
