[0037] That is, during the rotation of the valve core to switch between the open position and the closed position, the valve disc of the valve core and the sealing part do not rub against each other. On the one hand, the resistance of the valve core during rotation is small, and a smaller torque can also make the valve core rotate, which can reduce the load of the driving member for driving the valve core to rotate, allowing the valve structure to adopt a driving member with smaller torque to drive the valve core to rotate, reducing the cost of the driving member, and also facilitating the reduction of the size of the entire valve structure and the arrangement of the valve structure. On the other hand, the valve core seal is less likely to wear due to long-term contact with the valve core seal, and the service life of the valve core seal is longer.

[0038] Other features and advantages of the present disclosure will be described in detail in the following specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0056] The specific embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0057] In the present disclosure, it should be understood that the orientation words such as "up", "down", etc. used are defined with the direction of the drawing surface of FIG. 1, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, and a particular orientation configuration and operation, and therefore cannot be understood as a limitation on the present disclosure. The terms "inner" and "outer" refer to the inner and outer of the corresponding structure profile. In addition, it should be noted that the terms "first", "second", etc. used are for distinguishing one element from another element, and do not have sequentiality and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0058] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "linked", "mounted" should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0059] As shown in FIGS. 1 to 14, according to the first aspect of the present disclosure, a valve structure 100 is provided, which comprises a valve body 1, a valve core 2 and a valve core sealing member 3, the valve body 1 has an inlet 11 and an outlet 12, the valve core 2 is rotatably arranged in the valve body 1 and comprises a valve disc 21, the valve core sealing member 3 is mounted in the valve body 1 and comprises a sealing part 31 corresponding to the valve disc 21, a flow channel 32 capable of communicating the inlet 11 and the outlet 12 is formed on the sealing part 31, the valve core 2 and the valve core sealing member 3 are oppositely arranged along the rotation axis of the valve core 2, the sealing part 31 has a sealing surface 33, and the valve disc 21 has a contact surface 22 for sealing contact with the sealing surface 33.

[0060] The valve piece 21 has an open position and a closed position. In the open position, the valve piece 21 at least partially exposes the flow passage 32 to the first flow passage opening 321 of the valve piece 21, so that the liquid or gas flowing from the inlet 11 can flow to the outlet 12 through the flow passage 32. In the closed position, the valve piece 21 covers the first flow passage opening 321, and the contact surface 22 is in contact with the sealing surface 33, so that the liquid or gas flowing from the inlet 11 cannot flow into the flow passage 32 and the outlet 12. The contact surface 22 and the sealing surface 33 are configured to always have a gap between the contact surface 22 and the sealing surface 33 during switching of the valve piece 21 between the open position and the closed position.

[0061] In the valve structure 100 provided by the present disclosure, the inlet 11 and the outlet 12 are arranged on the valve body 1, the sealing portion 31 on the valve core sealing member 3 is formed with the flow passage 32 that can communicate the inlet 11 and the outlet 12 on the valve structure 100, the contact surface 22 is arranged on the valve piece 21 of the valve core 2 rotatably arranged in the valve body 1, and the sealing surface 33 is formed on the sealing portion 31 of the valve core sealing member 3 for sealing contact with the contact surface 22. Thus, when the contact surface 22 on the valve piece 21 is tightly attached to the contact surface 22 on the sealing portion 31, the flow passage 32 that communicates the inlet 11 and the outlet 12 of the valve structure 100 is disconnected by the valve piece 21; when the contact surface 22 on the valve piece 21 and the sealing surface 33 on the sealing portion 31 are detached from each other, the flow passage 32 that communicates the inlet 11 and the outlet 12 of the valve structure 100 is connected. In other words, by rotating the valve core 2 to tightly attach or detach the valve piece 21 and the sealing portion 31 of the valve core sealing member 3, the connection and disconnection of the inlet 11 and the outlet 12 of the valve structure 100 can be realized.

[0062] Here, it should be noted that in the valve structure 100 provided by the present disclosure, the contact surface 22 and the sealing surface 33 always have a gap between them during switching of the valve piece 21 between the open position and the closed position, which means that the contact surface 22 on the valve piece 21 and the sealing surface 33 on the sealing portion 31 always have a gap between them during rotation of the valve piece 21 from the open position to the closed position, and the contact surface 22 on the valve piece 21 and the sealing surface 33 on the sealing portion 31 also always have a gap between them during rotation of the valve piece 21 from the closed position to the open position. That is, whether the valve piece 21 is rotated from the open position to the closed position or from the closed position to the open position, the contact surface 22 on the valve piece 21 and the sealing surface 33 on the sealing portion 31 always have a gap between them, that is, the valve piece 21 on the valve core 2 does not contact and rub against the sealing portion 31 on the valve core sealing member 3. Only when the valve piece 21 is in the closed position, the contact surface 22 is in sealing contact with the sealing portion 31, that is, it is pressed against the sealing portion 31.

[0063] In addition, it should be noted that as long as the valve plate 21 can expose the position of the first flow passage opening 321 of the flow passage 32 close to the valve plate 21, whether it is the position of exposing part of the first flow passage opening 321 or the position of completely exposing the first flow passage opening 321, it belongs to the opening position of the valve plate 21; as long as the valve plate 21 can completely cover the position of the first flow passage opening 321, it belongs to the closing position of the valve plate 21. Therefore, it can be understood that the valve plate 21 can have multiple opening positions and multiple closing positions.

[0064] When the first flow passage opening 321 on the sealing portion 31 is just covered by the valve plate 21, the valve plate 21 is in the closing position, at this time, the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 can be arranged to be just in contact, with the continuous rotation of the valve core 21, the sealing portion 31 can be gradually pressed by the valve plate 21, that is, the extrusion force of the valve plate 21 on the sealing portion 31 gradually increases.

[0065] Through the above technical scheme, since the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 always have a gap between them during the switching of the valve plate 21 on the valve core 2 between the opening position and the closing position, this makes the valve plate 21 and the sealing portion 31 not contact during the rotation of the valve core 2, and the valve plate 21 and the sealing portion 31 do not generate frictional force, only when the valve plate 21 is in the closing position, the valve plate 21 will contact the sealing portion 31, thereby closing the flow passage 32 connecting the inlet 11 and the outlet 12.

[0066] That is, during the rotation of the valve core 2 to switch between the opening position and the closing position, the valve plate 21 of the valve core 2 and the sealing portion 31 will not rub each other, on the one hand, the resistance of the valve core 2 during rotation is small, a smaller torque can make the valve core 2 rotate, the load of the driving member 4 for driving the valve core 2 to rotate can be reduced, allowing the valve structure 100 to adopt a driving member 4 with smaller torque to drive the valve core 2 to rotate, reducing the cost of the driving member 4, also conducive to reducing the size of the entire valve structure 100, facilitating the arrangement of the valve structure 100; on the other hand, the valve core sealing member 3 is not easy to wear due to long-time sealing contact with the valve core 2, and the service life of the valve core sealing member 3 is longer.

[0067] The gap between the contact surface 22 and the sealing surface 33 can remain constant or can vary (e.g., gradually decrease, or first increase and then decrease, etc.) when the valve plate 21 switches between the open position and the closed position, which is not limited in the present disclosure. In an embodiment provided by the present disclosure, the contact surface 22 and the sealing surface 33 are configured to gradually decrease the gap between the contact surface 22 and the sealing surface 33 during the rotation of the valve plate 21 from the open position to the closed position. When the valve plate 21 is in the open position and the first flow passage port 321 is fully open, the gap between the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 is the largest. When the valve plate 21 rotates in the direction towards the closed position, the gap between the contact surface 22 on the valve plate 21 and the sealing surface 33 on the valve core sealing member 3 gradually decreases. When the valve plate 21 is in the closed position, the gap between the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 is zero, and the valve plate 21 is pressed against the valve core sealing member 3. The valve plate 21 on the valve core 2 cooperates with the valve core sealing member 3 to close the flow passage 32 between the inlet 11 and the outlet 12 of the communication valve structure 100.

[0068] The gap between the contact surface 22 and the sealing surface 33 is always present when the valve plate 21 switches between the open position and the closed position. When the valve core 2 rotates the valve plate 21 in the direction from the closed position to the open position, the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 are separated from each other. The gap between the contact surface 22 on the valve plate 21 and the sealing surface 33 on the sealing portion 31 gradually increases. The valve plate 21 gradually separates from the sealing portion 31 and opens the flow passage 32 between the inlet 11 and the outlet 12 of the communication valve structure 100.

[0069] The gap between the contact surface 22 and the sealing surface 33 is always present when the valve plate 21 switches between the open position and the closed position. The sealing contact between the contact surface 22 and the sealing surface can be achieved by various specific embodiments when the valve plate 21 is in the closed position. For example, an elastic air bag can be provided on the valve plate 21. When the valve plate 21 switches between the open position and the closed position, the elastic air bag is in an uninflated state, and the elastic air bag provided on the valve plate 21 does not contact the valve core sealing member 3. When the valve plate 21 is in the closed position, the elastic air bag can be in an inflated state. At this time, the volume of the elastic air bag increases, and the elastic air bag can tightly fit on the valve core sealing member 3, thereby closing the flow passage 32 between the inlet 11 and the outlet 12 of the communication valve structure 100.

[0070] In an example embodiment provided in the present disclosure, in order to gradually reduce the gap between the contact surface 22 on the valve plate 21 and the sealing surface 33 on the valve core seal 3 when the valve plate 21 rotates from the open position to the closed position, as shown in FIGS. 4-10, the distance between the sealing surface 33 of the corresponding sealing portion 31 of the valve plate 21 and the first reference plane 7 gradually increases in the rotation direction of the valve plate 21 from the open position to the closed position, the first reference plane 7 is located on the side of the sealing portion 31 away from the valve plate 21, and the distance between the contact surface 22 and the second reference plane 8 gradually decreases in the rotation direction of the valve plate 21 from the open position to the closed position, the second reference plane 8 is located on the side of the valve plate 21 away from the seal.

[0071] Here, it should be noted that the first reference plane 7 and the second reference plane 8 are not physical planes on the valve structure 100, but are virtual planes defined for the purpose of describing the shapes of the sealing surface 33 and the contact surface 22.

[0072] In order to facilitate understanding of the above technical solutions, the embodiment shown in FIGS. 6-9 is taken as an example for description, the rotation direction of the valve plate 21 from the open position to the closed position is the A1 direction (specifically, the rotation direction of the first valve plate 211 mentioned below) or the A2 direction (specifically, the rotation direction of the second valve plate 212 mentioned below) as shown in FIG. 6. Specifically, along the A1 direction, the distance between the sealing surface 33 of the sealing portion 31 (specifically, the first sealing portion 311 mentioned below) and the first reference plane 7 gradually increases (e.g., from D1 to D2); along the A2 direction, the distance between the sealing surface 33 of the sealing portion 31 (specifically, the second sealing portion 312 mentioned below) and the first reference plane 7 gradually increases (e.g., from D3 to D2).

[0073] That is, along the rotation direction of the valve plate 21 from the open position to the closed position, the height of the sealing surface 33 of the corresponding sealing portion 31 of the valve plate 21 (i.e., the distance between the sealing surface 33 and the lower edge of the drawing plane in FIG. 6) gradually increases.

[0074] For the valve plate 21, referring to FIG. 9, along the A1 direction, the distance between the contact surface 22 and the second reference plane 8 gradually decreases (e.g., from L1 to L2). That is, along the rotation direction of the valve plate 21 from the open position to the closed position, the height of the contact surface 22 (i.e., the distance between the contact surface 22 and the lower edge of the drawing plane in FIG. 9) gradually increases.

[0075] In other words, the sealing surface 33 and the contact surface 22 are both inclined surfaces, and the thickness of the sealing gasket of the valve core 2 gradually increases and the thickness of the valve plate 21 gradually decreases in the rotation direction of the valve plate 21 from the open position to the closed position. As shown in FIGS. 6 and 9, in the process of the valve plate 21 rotating from the open position to the closed position, the highest point of the contact surface 22 first enters the area above the sealing surface 33, and the highest point of the contact surface 22 and the lowest point of the sealing surface 33 have the maximum distance. As the valve plate 21 continues to rotate, the distance between the contact surface 22 and the sealing surface 33 gradually decreases, and the highest point of the contact surface 22 moves towards the highest point of the sealing surface 33. When the highest point of the contact surface 22 and the highest point of the sealing surface 33 are aligned in the up-down direction, the contact surface 22 and the sealing surface 33 are in close contact with each other, and sealing contact is achieved.

[0076] In order to improve the sealing effect between the valve plate 21 and the valve core sealing element 3, as an embodiment of the present disclosure, as shown in FIGS. 6 and 10, the distance between the sealing surface 33 and the first reference plane 7 gradually increases in the direction from the side of the sealing portion 31 close to the rotation axis of the valve core 2 to the side of the sealing portion 31 away from the rotation axis of the valve core 2, and the distance between the contact surface 22 and the second reference plane 8 gradually decreases in the direction from the side of the valve plate 21 close to the rotation axis of the valve core 2 to the side of the valve plate 21 away from the rotation axis of the valve core 2.

[0077] Here, as shown in FIG. 6, the distance between the side of the sealing portion 31 close to the rotation axis of the valve core 2 and the first reference plane 7 is H1, and the distance between the side of the sealing portion 31 away from the rotation axis of the valve core 2 and the first reference plane is H2. In the direction from the side of the sealing portion 31 close to the rotation axis of the valve core 2 to the side away from the rotation axis of the valve core 2 (A3 direction or A4 direction in FIG. 6), H1 gradually increases to H2.

[0078] As shown in FIG. 10, the distance between the side of the contact surface 22 close to the rotation axis and the second reference plane 8 is N1, and the distance between the side of the contact surface away from the rotation axis and the second reference plane 8 is N2 or N3. In the direction from the side of the valve plate 21 close to the rotation axis of the valve core 2 to the side of the valve plate 21 away from the rotation axis of the valve core 2 (A5 direction or A6 direction in FIG. 10), N1 gradually decreases to N2 or N3.

[0079] That is, the sealing surface 33 is inclined towards one side, and the contact surface 22 is inclined towards the side opposite to the inclination direction of the sealing surface 33. In this way, the contact surface 22 and the sealing surface 33 can be designed as mutually matching spiral curved surfaces. The inclined contact surface 22 and the sealing surface 33 have a larger area, thereby increasing the contact area between the contact surface 22 and the sealing surface 33 and improving the sealing effect between the valve plate 21 and the valve core sealing element 3.

[0080] The thickness of the sealing portion 31 can gradually increase in a direction from a side of the sealing portion 31 close to the rotation axis of the valve core 2 to a side of the sealing portion 31 away from the rotation axis of the valve core 2 (e.g., the A3 direction or the A4 direction in FIG. 6), and the thickness of the valve plate 21 can gradually decrease in a direction from a side of the valve plate 21 close to the rotation axis of the valve core 2 to a side of the valve plate 21 away from the rotation axis of the valve core 2 (e.g., the A5 direction or the A6 direction in FIG. 10).

[0081] As another embodiment of the present disclosure, the distance between the sealing surface 33 and the first reference plane 7 can gradually decrease in a direction from a side of the sealing portion 31 close to the rotation axis of the valve core 2 to a side of the sealing portion 31 away from the rotation axis of the valve core 2, and the distance between the contact surface 22 and the second reference plane 8 can gradually increase in a direction from a side of the valve plate 21 close to the rotation axis of the valve core 2 to a side of the valve plate 21 away from the rotation axis of the valve core 2. In this way, the contact surface 22 and the sealing surface can also be designed as helical curved surfaces, so as to increase the contact area between the contact surface 22 and the sealing surface 33 and improve the sealing effect between the valve plate 21 and the valve core 2.

[0082] The valve structure 100 described above can be a switch valve for realizing the conduction or blocking of fluid or gas, or a reversing valve (i.e., a multi-way valve) for realizing the reversing of fluid or gas, and the present disclosure does not limit this. The present disclosure also does not limit the specific number of valve plates 21 on the valve core 2. The number of valve plates 21 can be one or multiple, and correspondingly, the number of sealing portions 31 can be one or multiple. As an embodiment of the present disclosure, as shown in FIGS. 3, 7, 8, and 10, the valve plate 21 is multiple, the multiple valve plates 21 include a first valve plate 211 and a second valve plate 212, the sealing portion 31 is multiple, the multiple sealing portions 31 include a first sealing portion 311 and a second sealing portion 312, the outlet 12 is multiple, the multiple outlets 12 include a first outlet 121 and a second outlet 122, the flow channel 32 on the first sealing portion 311 is used to communicate the inlet 11 and the first outlet 121, the first valve plate 211 is used to expose or cover the first flow channel opening 321 of the flow channel 32 on the first sealing portion 311 close to the first valve plate 211, the flow channel 32 on the second sealing portion 312 is used to communicate the inlet 11 and the second outlet 122, and the second valve plate 212 is used to expose or cover the first flow channel opening 321 of the flow channel 32 on the second sealing portion 312 close to the second valve plate 212.

[0083] In this way, the fluid flowing out of the valve structure 100 through the inlet 11 can flow to the flow channel 32 on the first sealing portion 311 or the flow channel 32 on the second sealing portion 312, wherein the first valve plate 211, the first sealing portion 311 and the first outlet 121 are correspondingly arranged, the first valve plate 211 cooperates with the first sealing portion 311 to open or close the first flow port 321 of the flow channel 32 on the first sealing portion 311, so that the fluid flowing out of the valve structure 100 through the inlet 11 can selectively flow out of the first outlet 121. The second valve plate 212, the second sealing portion 312 and the second outlet 122 are correspondingly arranged, the second valve plate 212 cooperates with the first flow port 321 of the flow channel 32 on the second sealing portion 312 to open or close the first flow port 321 of the flow channel 32 on the second sealing portion 312, so that the fluid flowing out of the valve structure 100 through the inlet 11 can selectively flow out of the second outlet 122. In this way, by controlling the opening or closing of the first flow port 321 of the flow channel 32 on the first sealing portion 311 and / or the first flow port 321 of the flow channel 32 on the second sealing portion 312, the valve structure 100 can have different conduction states.

[0084] Optionally, as shown in FIGS. 4-6, the first sealing portion 311 and the second sealing portion 312 are arranged side by side along the rotation direction of the valve core 2 and are connected to each other, and the first valve plate 211 and the second valve plate 212 are arranged at intervals along the rotation direction of the valve core 2, so that when the valve core 2 rotates, one of the first valve plate 211 and the second valve plate 212 can rotate from its open position to its closed position, and the other of the first valve plate 211 and the second valve plate 212 can rotate from its closed position to its open position.

[0085] For example, when the valve core 2 rotates in a first direction, the first valve plate 211 rotates from its open position to its closed position, and the second valve plate 212 rotates from its closed position to its open position; when the valve core 2 rotates in a second direction opposite to the first direction, the first valve plate 211 rotates from its closed position to its open position, and the second valve plate 212 rotates from its open position to its closed position.

[0086] In this way, during use of the valve structure 100, when one of the two valve plates 21 (i.e. the first valve plate 211 and the second valve plate 212) rotates from its open position towards its closed position, the opening of the first flow port 321 of the flow channel 32 on the corresponding sealing portion 31 of the valve plate 21 gradually decreases, while the opening of the first flow port 321 of the flow channel on the corresponding sealing portion 31 of the other valve plate 21 gradually increases. Both valve plates 21 can also be in the open position, for example, as shown in FIG. 3, when the first valve plate 211 rotates towards the Al direction, the rotation direction of the first valve plate 211 is from its open position to its closed position, the opening of the first flow port 321 of the flow channel 32 on the first sealing portion 311 gradually decreases, the rotation direction of the second valve plate 212 is from its closed position to its open position, the opening of the first flow port 321 of the flow channel 32 on the second sealing portion 312 gradually increases, and when the first valve plate 211 and the second valve plate 212 do not completely cover the first flow port 321 of the flow channel 32 on the first sealing portion 311 and the first flow port 321 of the flow channel 32 on the second sealing portion 312, the first flow port 321 of the flow channel 32 on the first sealing portion 311 and the first flow port 321 of the flow channel 32 on the second sealing portion 312 are both in the open state.

[0087] By reasonably adjusting the rotation angle of the valve core 2, the inlet 11 and the first outlet 121 and the second outlet 122 of the valve structure 100 can be simultaneously communicated, and the fluid can flow to different flow paths through the first outlet 121 and the second outlet 122. Moreover, by reasonably adjusting the rotation angle of the first valve plate 211 and the second valve plate 212, the opening of the first flow port 321 of the flow channel 32 on the first sealing portion 311 and the first flow port 321 of the flow channel 32 on the second sealing portion 312 can be adjusted, so that the fluid flowing into the valve structure 100 through the inlet 11 can flow to different flow paths through different outlets 12 in different proportions.

[0088] In addition, by adjusting the rotation angle of the first valve plate 211 and the second valve plate 212, one of the two valve plates 21 can be attached to the corresponding sealing portion 31, so as to close the flow channel 32 on the corresponding sealing portion 31 of the valve plate 21, while completely opening the flow channel 32 on the corresponding sealing portion 31 of the other valve plate 21. For example, the first valve plate 211 is attached to the first sealing portion 311, and the first flow port 321 of the flow channel 32 on the first sealing portion 311 is closed, at this time, the second valve plate 212 is offset from the second sealing portion 312, and the first flow port 321 of the flow channel 32 on the second sealing portion 322 is in a completely open state, so that the fluid flowing into the valve structure 100 through the inlet 11 can flow out from only one outlet 12 as needed.

[0089] It should be noted that, for the embodiment in which the valve plate 21 comprises the first valve plate 211 and the second valve plate 212, the sealing part 31 comprises the first sealing part 311 and the second sealing part 312, and the first sealing part 311 and the second sealing part 312 are arranged side by side along the rotation direction of the valve core 2 and are connected to each other, for the embodiment in which the first valve plate 211 and the second valve plate 212 are arranged at intervals along the rotation direction of the valve core 2, in order to make the gap between the contact surface 22 and the sealing surface 33 gradually decrease during the rotation of the first valve plate 211 and the second valve plate 212 from the open position to the closed position. Alternatively, along the rotation direction of the first valve plate 211 from the open position to the closed position, i.e. along the A1 direction in FIGS. 6 and 9, the distance between the sealing surface 33 of the sealing part 31 corresponding to the first valve plate 211 and the first reference plane 7 gradually increases, and along the rotation direction of the first valve plate 211 from the open position to the closed position, the distance between the contact surface 22 of the first valve plate 211 and the second reference plane 8 gradually decreases.

[0090] In addition, along the rotation direction of the second valve plate 212 from the open position to the closed position, i.e. along the A2 direction in FIG. 6, the distance between the sealing surface 33 of the sealing part 31 corresponding to the second valve plate 212 and the second reference plane 8 gradually increases, and along the rotation direction of the second valve plate 212 from the open position to the closed position, the distance between the contact surface 22 of the second valve plate 212 and the second reference plane 8 gradually decreases.

[0091] In other words, the rotation directions of the contact surface 22 on the first valve plate 211 and the contact surface 22 on the second valve plate 212 are opposite, and the rotation directions of the sealing surface 33 on the first sealing part 311 and the second sealing part 312 are also opposite.

[0092] For the embodiment in which the valve structure 100 comprises the first outlet 121 and the second outlet 122, in order to split the fluid flowing in via the inlet 11, optionally, as shown in FIG. 11, the inside of the valve body 1 is provided with a partition 13, the partition 13 divides the inside of the valve body 1 into a liquid inlet cavity 14, a first liquid outlet cavity 15, and a second liquid outlet cavity 16, the inlet 11 communicates with the liquid inlet cavity 14, the first outlet 121 communicates with the first liquid outlet cavity 15, the second outlet 122 communicates with the second liquid outlet cavity 16, the flow channel 32 on the first sealing part 311 can communicate the liquid inlet cavity 14 and the first liquid outlet cavity 15, and the flow channel 32 on the second sealing part 312 can communicate the liquid inlet cavity 14 and the second liquid outlet cavity 16. The partition 13 can play a role in separating the internal space of the valve body 1, and the fluid flowing into the valve body 1 via the inlet 11 can flow out from the first outlet 121 through the flow channel 32 on the first sealing part 311, the first liquid outlet cavity 15, or flow out from the second outlet 122 through the flow channel 32 on the second sealing part 312, the second liquid outlet cavity 16.

[0093] The present disclosure does not limit the shape of the valve disc 21 arranged on the valve core 2 and the sealing portion 31 on the valve core sealing member 3. As an embodiment of the present disclosure, the sealing portion 31 and the valve disc 21 are both formed in a fan-shaped structure, as shown in FIGS. 3-11. Since the sealing portion 31 and the valve disc 21 are both formed in a fan-shaped structure, the valve disc 21 can be easily matched with the sealing portion 31 during rotation.

[0094] Optionally, the cross-sectional shape of the flow channel 32 on the sealing portion 31 can also be formed in a fan shape. The fan-shaped flow channel 32 is matched with the fan-shaped valve disc 21, which is advantageous for more accurately controlling the flow rate of the fluid flowing through the flow channel 32.

[0095] Here, it can be understood that for the embodiment in which the valve disc 21 includes the first valve disc 211 and the second valve disc 212, and the sealing portion 31 includes the first sealing portion 311 and the second sealing portion 312, the first valve disc 211, the second valve disc 212, the first sealing portion 311, and the second sealing portion 312 can all be formed in a fan-shaped structure.

[0096] In order to accurately control the position of the valve core 2 during rotation, optionally, as shown in FIGS. 3, 7, 8, and 12, a stop portion 213 is arranged on the valve disc 21, and a stop member 17 is arranged in the valve body 1, which is used to abut against the stop portion 213 to limit the rotation angle of the valve core 2. In this way, during rotation of the valve core 2, if the valve disc 21 is rotated to the limit position under the rotation of the valve core 2, for example, the valve disc 21 has reached the open position (or the valve disc 21 has reached the closed position), at this time, the stop member 17 in the valve body 1 can abut against the stop portion 213 on the valve disc 21, and the valve disc 21 cannot continue to rotate. At this time, the valve core 2 can only rotate towards the direction of its closed position (or open position). Thus, only by driving the valve core 2 to rotate in different directions (such as the A1 direction or the A2 direction in FIG. 6) so that the valve disc 21 on the valve core 2 is rotated to be able to abut against the stop member 17, the valve disc 21 can be in a fully open or fully closed state. This effectively avoids the situation that during production and manufacturing of the valve structure 100, due to manufacturing and / or assembly errors, although the valve core 2 is rotated by a corresponding angle, the position between the valve disc 21 and the valve core sealing member 3 is deviated, and the valve disc 21 cannot be in a fully open or fully closed state.

[0097] It can be understood that, as shown in FIG. 3 and FIG. 12, for the embodiment in which the valve plate 21 comprises the first valve plate 211 and the second valve plate 212, and the sealing part 31 comprises the first sealing part 311 and the second sealing part 312, the first valve plate 211 and the second valve plate 212 are both provided with the stop part 213, the stop part 213 on the first valve plate 211 and the stop part 213 on the second valve plate 212 are oppositely arranged, and the stop piece 17 is arranged between the stop part 213 on the first valve plate 211 and the stop part 213 on the second valve plate 212.

[0098] The specific structure of the valve body 1 is not limited in the present disclosure, and as an embodiment of the present disclosure, the valve body 1 comprises the valve seat 18 and the valve cover 19 arranged on the valve seat 18, the valve core 2 and the valve core sealing piece 3 are both located in the valve seat 18, the inlet 11 and the outlet 12 are formed on the valve seat 18. The stop part 213 can be a stop groove 214 formed on the valve plate 21, and the stop piece 17 is a stop block mounted on the valve cover 19, one end of the stop block extending into the valve seat 18.

[0099] The specific connection relationship between the valve core sealing piece 3 and the valve body 1 is not limited in the present disclosure, and as an embodiment of the present disclosure, as shown in FIG. 5 and FIG. 12, the sealing part 31 is provided with the first clamping part 313 on the side away from the valve plate 21, and the valve body 1 is provided with the second clamping part 20 for clamping cooperation with the first clamping part 313, the first clamping part 313 and the second clamping part 20 both surround the second flow passage opening 322 of the flow passage 32 away from the valve plate 21. The valve core sealing piece 3 is connected with the valve body 1 through clamping cooperation, and the installation of the valve core sealing piece 3 on the valve body 1 is reliable, which effectively avoids the displacement of the valve core sealing piece 3 and the deviation of the position between the valve plate 21 and the valve core sealing piece 3 in the use process, and the valve plate 21 on the valve core 2 cannot cooperate with the sealing part 31 on the valve core sealing piece 3.

[0100] In order to drive the valve core 2 to rotate, optionally, as shown in FIG. 2, the above-mentioned valve structure 100 can further comprise a driving piece 4 and a rotating shaft 5, the driving piece 4 is located outside the valve body 1, the valve body 1 is formed with a through hole 30 for the rotating shaft 5 to pass through, the driving piece 4 is connected with the valve core 2 through the rotating shaft 5, and the driving piece 4 can drive the valve core 2 to rotate, so as to open or close the flow passage 32 connecting between the inlet 11 and the outlet 12 in the valve structure 100, thereby realizing the control of the on-off of the flow passage 32 in the above-mentioned valve structure 100.

[0101] In order to avoid the rotation shaft 5 from shaking during rotation, optionally, as shown in FIG. 2, FIG. 13 and FIG. 14, a fixing block 6 is arranged in the through hole 30, the rotation shaft 5 is arranged in the fixing block 6, the valve core 2 further comprises a connecting portion 23 connected with the valve plate 21, the connecting portion 23 is sleeved on the rotation shaft 5, the first recess 61 is arranged on the side of the fixing block 6 close to the connecting portion 23, the second recess 231 is arranged on the side of the connecting portion 23 close to the fixing block 6, and the first recess 61 and the second recess 231 are used for storing lubricating grease. The fixing block 6 can limit the rotation shaft 5, effectively avoid the rotation shaft 5 from shaking along the radial direction during rotation, and the stability of the valve structure 100 is good.

[0102] In addition, the first recess 61 is arranged on the side of the fixing block 6 close to the connecting portion 23, the second recess 231 is arranged on the side of the connecting portion 23 close to the fixing block 6, and the first recess 61 and the second recess 231 are used for storing lubricating grease. The lubricating grease can lubricate the valve core 2 and the fixing block 6, and effectively reduce the friction between the connecting portion 23 and the fixing block 6 during rotation of the valve core 2.

[0103] In order to further reduce the friction between the connecting portion 23 of the valve core 2 and the fixing block 6, optionally, as shown in FIG. 2, FIG. 8 and FIG. 14, the first recess 61 and the second recess 231 are staggered along the radial direction of the rotation shaft 5. Since the first recess 61 and the second recess 231 are used for storing lubricating grease, the first recess 61 and the second recess 231 staggered along the radial direction of the rotation shaft 5 can increase the lubricating area between the connecting portion 23 of the valve core 2 and the fixing block 6, thereby further reducing the friction between the connecting portion 23 of the valve core 2 and the fixing block 6.

[0104] In order to avoid the fixing block 6 from falling off the through hole 30 of the valve body 1, optionally, as shown in FIG. 13, a plurality of clamping legs 62 are arranged on the fixing block 6 and are arranged at intervals along the circumferential direction of the fixing block 6, and a guide inclined surface 63 is arranged on the side of each clamping leg 62 close to the through hole 30. In this way, when the fixing block 6 is inserted into the through hole 30 of the valve body 1, the clamping leg 62 on the fixing block 6 can abut against the inner wall of the through hole 30, the fixing block 6 and the through hole 30 can be formed in an interference fit, the fixing block 6 is fixed on the valve body 1 reliably and is not easy to fall off.

[0105] In addition, the guide inclined surface 63 can guide the fixing block 6, thereby facilitating the insertion of the fixing block 6 into the through hole 30.

[0106] In order to facilitate the rotation of the valve core 2, optionally, as shown in FIG. 8, a weight-reducing groove 24 can also be arranged on the side of the valve plate 21 away from the valve core seal 3. By opening the weight-reducing groove 24, the weight of the valve core 2 can be reduced, so that the torque required for driving the valve core 2 to rotate can be reduced, facilitating the rotation of the valve core 2, and at the same time, it is also beneficial to reduce the weight of the entire valve structure 100.

[0107] According to a second aspect of the present disclosure, as shown in FIG. 15, a thermal management system 200 is provided, comprising the valve structure 100 as described above.

[0108] The thermal management system 200 has all the beneficial effects of the valve structure 100 described above, which will not be repeated here.

[0110] The vehicle 1000 has all the beneficial effects of the valve structure 100 or the thermal management system 200 described above, which will not be repeated here.
