Description

Technical Field

[0001] This invention relates to the field of thermal management technology, and in particular to a fluid control component. Background Technology

[0002] Typically, the valve core of a fluid control component rotates under the drive of a driving component to achieve fluid control of multiple flow paths. In order to achieve multiple working modes, existing fluid control components need to set multiple water valves to achieve the corresponding working modes, or they need to set multiple interfaces on the valve body and multiple conduction ports on the valve core to achieve the corresponding working modes, resulting in a relatively complex overall structure of the fluid control component. Summary of the Invention

[0003] Therefore, it is necessary to provide a fluid control component that can achieve multiple working modes and has a relatively simple overall structure to address the above problems.

[0004] The present invention provides a fluid control component, comprising a valve body and a valve core. The valve body has a valve cavity, and its axial end face has at least two interface regions spaced apart along the circumference of the valve body, each interface region having at least two interfaces. At least a portion of the valve core is rotatably disposed within the valve cavity, and its axial end face has at least two conduction regions spaced apart along the circumference of the valve core. The circumferential interval angle between the at least two conduction regions corresponds to the circumferential interval angle between the at least two interface regions. Each conduction region has a conduction port penetrating the axial end face of the valve core, and the conduction port is capable of connecting at least two interfaces in any interface region.

[0005] The present invention provides a fluid control component, wherein the valve body integrates at least two interface areas, and each interface area has at least two interfaces, and the valve core integrates at least two conduction areas, each conduction area having a conduction port, which can conduct at least two interfaces in any interface area. One interface area and one conduction area can realize the corresponding working mode. Therefore, the fluid control component can have multiple working modes through one valve body and one valve core, and the overall structure of the fluid control component is relatively simple.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] Please see Figures 1 to 4 ,as well as Figure 14The fluid control assembly includes a valve body 1, a valve core 2, a first sealing gasket 31, a second sealing gasket 32, a first sealing ring 33, a second sealing ring 34, an elastic element 4, a first wear-resistant structure 5, a second wear-resistant structure 6, and a controller 7.

[0030] The valve body 1 has a valve cavity 111. The axial end face of the valve body 1 has at least two interface areas 130 spaced apart along the circumference of the valve body 1. Each interface area 130 has at least two interfaces 121. At least a portion of the valve core 2 is rotatably disposed in the valve cavity 111. The axial end face of the valve core 2 has at least two conduction areas 27 spaced apart along the circumference of the valve core 2. The circumferential interval angle between the at least two conduction areas 27 corresponds to the circumferential interval angle between the at least two interface areas 130. Each conduction area 27 has a conduction port 21 penetrating the axial end face of the valve core 2. The conduction port 21 can conduct at least two interfaces 120 in any interface area 130.

[0031] It is conceivable that the fluid control component provided by this technical solution integrates at least two interface areas 130 on the valve body 1 and at least two conduction areas 27 on the valve core 2. Each conduction area 27 has a conduction port 21, which can conduct at least two interfaces 121 in the interface area 130, thereby realizing the corresponding working mode. The overall structure of the fluid control component is simple.

[0032] It should be clear that in this technical solution, there are two interface areas 130, and the two interface areas 130 are distributed at intervals along the circumference of the valve body 1. For more details, please refer to... Figure 3 With the transverse centerline of valve body 1 as the boundary, the area above the transverse centerline is one interface area 130, and the area below the transverse centerline is the other interface area 130. There are two conduction areas 27, and the circumferential interval angle between the two conduction areas 27 corresponds to the circumferential interval angle between the two interface areas 130, that is, each conduction area 27 can correspond to one of the interface areas 130.

[0033] The valve body 1 includes a first valve body 11 and a second valve body 12. The first valve body 11 is located on one axial side of the second valve body 12, and the second valve body 12 is fixed to the first valve body 11, which can be welded.

[0034] The first valve body 11 has at least a portion of the wall defining the valve cavity 111, and the second valve body 12 may also have at least a portion of the wall defining the valve cavity 111. After the first valve body 11 and the second valve body 12 are fixed together, a complete valve cavity 111 is formed. At least a portion of the valve core 2 is rotatably disposed within the valve cavity 111.

[0035] The valve core 2 has a through port 21 on its axial end face facing the second valve body 12. The through port 21 includes at least a first through port 211 and a second through port 212, and the first through port 211 and the second through port 212 are spaced apart along the circumference of the valve core 2. The first through port 211 is located in one of the conduction areas 27, and the second through port 212 is located in the other conduction area 27.

[0036] In at least one mode of the fluid control assembly, a first port 211 is connected to at least three interfaces 121, two of the interfaces 121 connected to the first port 211 are spaced apart along the rotation direction of the valve core 2, and a second port 212 is connected to at least two interfaces 121.

[0037] It is conceivable that, since the two interfaces 121 connected to the first guide port 211 are arranged at intervals along the rotation direction of the valve core 2, when the valve core 2 rotates, the first guide port 211 rotates with the valve core 2, and the conduction area between the first guide port 211 and the two interfaces 121 can be changed. Specifically, the conduction area between the first guide port 211 and one of the interfaces 121 increases, and the conduction area between the first guide port 211 and the other interface 121 decreases. In other words, as the valve core 2 rotates, the flow rate of these two interfaces can be adjusted, that is, the fluid control component can have the function of flow regulation.

[0038] It should be noted that the valve body 1 is roughly cylindrical in shape. Therefore, the direction of the central axis of the valve body 1 is defined as the axial direction, the direction of the diameter of the valve body 1 is defined as the radial direction, and the direction of the circumference of the valve body 1 is defined as the circumferential direction. The axial direction of the valve body 1 is parallel to or coincides with the axial direction of the valve core 2.

[0039] The second valve body 12 has a circumferentially spaced portion 122, and adjacent circumferentially spaced interfaces 121 are separated by the circumferentially spaced portion 122. The central angle of the inner wall of the guide port 21 is greater than the central angle of the circumferentially spaced portion 122. It should be noted that the central angle of the circumferentially spaced portion 122 refers to the maximum central angle of the circumferentially spaced portion 122. Therefore, along the axial direction of the valve body 1, a portion of the projection of the guide port 21 can overlap with the projection of the circumferentially spaced portion 122, that is, the projection of the circumferentially spaced portion 122 can be located inside the projection of the guide port 21, a portion of the projection of the guide port 21 can overlap with a portion of the projection of one interface 121, and a portion of the projection of the guide port 21 can overlap with a portion of the projection of another interface 121.

[0040] Therefore, since the central angle of the through port 21 is larger than the central angle of the circumferential spacing portion 122, the through port 21 can span at least two ports 121 and the circumferential spacing portion 122 arranged circumferentially along the valve body 1. In other words, the through port 21 can connect at least two ports 121 arranged circumferentially along the valve body 1. Based on this, rotating the valve core 2 can change the conduction area between the through port 21 and these two ports 121, thereby achieving flow regulation.

[0041] The second valve body 12 has a radially spaced portion 123, which separates radially adjacent interfaces 121. Since in this embodiment, each interface 121 has two radial arrangement methods—that is, some interfaces 121 are located radially outside of another portion of interfaces 121—only one radially spaced portion 123 is needed to radially separate these two portions of interfaces 121. The radially spaced portion 123 can be a complete ring.

[0042] Along the radial direction of the valve core 2, the radial width of the guide port 21 can be greater than the radial width of the radial spacing portion 123. Along the axial direction of the valve body 1, a portion of the projection of the inner wall of the guide port 21 overlaps with the projection of the radial spacing portion 123. That is, the projection of the radial spacing portion 123 can be located within the projection of the inner wall of the guide port 21. A portion of the projection of the guide port 21 overlaps with a portion of the projection of one of the interfaces 121, and a portion of the projection of the guide port 21 overlaps with a portion of the projection of the other interface 121. It should be noted that of the two interfaces 121 that overlap with the portion of the projection of the inner wall of the guide port 21, one interface 121 is located radially inner to the radial spacing portion 123, and the other interface 121 is located radially outer to the radial spacing portion 123.

[0043] Therefore, since the radial width of the guide port 21 is greater than the radial width of the radial spacing portion 123, the guide port 21 can span two interfaces 121 and the radial spacing portion 122 along the radial direction of the valve body 1. In other words, the guide port 21 can connect at least two radially arranged interfaces 121 along the radial direction of the valve body 1.

[0044] In summary, in at least one mode of the fluid control component, among the interfaces 121 connected by the first guide port 211, at least two interfaces 121 need to be spaced circumferentially, and the first guide port 211 is connected to these two interfaces 121. Rotating the valve core 2 changes the conduction area between the first guide port 211 and these two interfaces 121, thereby achieving flow regulation. Simultaneously, among the interfaces 121 connected by the second guide port 212, each interface 121 needs to be spaced radially. The second guide port 212 is connected to each interface 121, and the conduction area between the second guide port 212 and each interface 121 remains unchanged when the valve body 1 is rotated.

[0045] The controller 7 is fixed to the first valve body 11, optionally using fasteners for connection. The controller 7 may include a motor and a gear set, and the valve core 2 may include a drive shaft. The drive shaft may be provided with splines, which can mesh with the gear set, so the motor can drive the valve core 2 to rotate through the gear set. In addition, the drive shaft can pass through the through hole of the first valve body 11 and be located outside the first valve body 11. The drive shaft can be radially limited by the inner wall of the through hole, that is, the inner wall of the through hole can restrict the radial movement of the valve core 2, thereby improving the coaxiality of the valve core 2.

[0046] In addition, the first sealing ring 33 can be sleeved on the outside of the drive shaft, and the first sealing ring 33 can abut against the inner wall of the first valve body 11, thereby enhancing the sealing between the valve core 2 and the first valve body 11.

[0047] Interface 121 includes a first interface 1211, a second interface 1212, a third interface 1213, a fourth interface 1214, a fifth interface 1215, and a sixth interface 1210, wherein the sixth interface 1210 includes a first sub-port 1216 and a second sub-port 1217. Specifically, the first interface 1211 and the fifth interface 1215 are arranged circumferentially.

[0048] The first interface 1211, the second interface 1212, and the third interface 1213 are located within an interface area 130. The second interface 1212 and the third interface 1213 are located radially outside the first interface 1211, and the second interface 1212 and the third interface 1213 are spaced apart along the circumference of the valve body 1.

[0049] The fourth interface 1214, the fifth interface 1215, and the sixth interface 1210 are located within another interface area 130. The fourth interface 1214 and the sixth interface 1210 are located radially outside the fifth interface 1215, and the fourth interface 1214 and the sixth interface 1216 are arranged alternately along the circumference. Specifically, the first sub-port 1216 and the second sub-port 1217 are located on both sides of the fourth interface 1214, and the first sub-port 1216 is adjacent to the second interface 1212, and the second sub-port 1217 is adjacent to the third interface 1213.

[0050] With the central axis of valve core 2 as the center, the first guide port 211 and the second guide port 212 are symmetrically arranged.

[0051] The third interface 1213 is symmetrically arranged with the first sub-port 1216 and part of the fourth interface 1214. In at least one mode of the fluid control component, the first through port 211 connects the first interface 1211 and the third interface 1213, and the second through port 212 connects the fifth interface 1215, part of the fourth interface 1214 and the first sub-port 1216.

[0052] The second interface 1212 is symmetrically arranged with the second sub-port 1217 and part of the fourth interface 1214. In at least one mode of the fluid control component, the first through port 211 connects the first interface 1211 and the second interface 1212, and the second through port 212 connects the fifth interface 1215, part of the fourth interface 1214, and the second sub-port 1217.

[0053] The fourth interface 1214 is symmetrically arranged with part of the second interface 1212 and part of the third interface 1213. In at least one mode of the fluid control component, the first conductive cavity 211 connects the first interface 1211, part of the second interface 1212 and part of the third interface 1213, and the second conductive port 212 connects the fifth interface 1215 and the fourth interface 1214.

[0054] The fluid control unit has at least one of seven operating modes:

[0055] Please see Figure 5 The first mode: the first interface 1211 and the third interface 1213 are connected, and the fourth interface 1214 and the fifth interface 1215 are connected.

[0056] Please see Figure 6 The second mode: the first interface 1211 and the third interface 1213 are connected, and the fifth interface 1215 and the first sub-port 1216 are connected;

[0057] Please see Figure 7 The third mode: the first interface 1211 and the second interface 1212 are connected, and the fourth interface 1214 and the fifth interface 1215 are connected.

[0058] Please see Figure 8 The fourth mode: the first interface 1211 and the second interface 1212 are connected, and the fifth interface 1215 and the second sub-port 1217 are connected;

[0059] It should be noted that in the first to fourth modes, the first conduction port 211 and the second conduction port 212 both conduct two interfaces 121. In other words, in these four working modes, by rotating the valve core 2, the conduction port 21 can conduct a specific interface 121, thereby realizing different working modes.

[0060] Please see Figure 9 The fifth mode: the first interface 1211 is connected to the third interface 1213, and the fifth interface 1215 is connected to part of the fourth interface 1214 and the first sub-port 1216.

[0061] Please see Figure 10 The sixth mode: the first interface 1211 and the second interface 1212 are connected, and the fifth interface 1215 is connected with part of the fourth interface 1214 and the second sub-port 1217.

[0062] Please see Figure 3 The seventh mode: the first interface 1211 is connected to part of the second interface 1212 and part of the third interface 1213, and the fifth interface 1215 is connected to the fourth interface 1214.

[0063] It should be noted that in modes five through seven, one of the connecting ports 21 can connect two interfaces 121, and the other connecting port 21 can connect three interfaces 121. Furthermore, two of these three interfaces 121 are spaced apart circumferentially. In other words, in these three working modes, by rotating the valve core 2, one connecting port 21 can connect a specific interface 121, and the other connecting port 21 can regulate the flow rate.

[0064] In addition, in these seven operating modes, the first interface 1211 and the fifth interface 1215 can be used as inlets, while the second interface 1212, the third interface 1213, the fourth interface 1214, the first sub-port 1216, and the second sub-port 1217 can be used as outlets. Based on this, in modes five through seven, taking mode five as an example, the fifth interface 1215 is connected to part of the fourth interface 1214 and the first sub-port 1216 through the second conductive port 212. As the valve core 2 rotates, the conductive area between the fifth interface 1215 and the second conductive port 212 remains constant, while the conductive area between the fifth interface 1215 and the fourth interface 1214 and the first sub-port 1216 continuously changes. That is, the refrigerant flow rate into the fifth interface 1215 remains constant, while the refrigerant flow rate out of the fourth interface 1214 and the first sub-port 1216 continuously changes with the rotation of the valve core 2. Modes six and seven are the same as mode five and will not be described further.

[0065] Importantly, since the outlet is located radially outside the inlet, in order to maintain a constant conductive area between the guide port 21 and the outlet in one operating mode, the guide port 21 can be connected to both inlets. Therefore, the shape of the guide port 21 can be fan-shaped. Specifically, the dimension of the guide port 21 near the central axis of the valve core 2 is smaller than the dimension of the conductive cavity away from the central axis of the valve core 2. Thus, as the valve core 2 rotates, the circumferential displacement distance of the smaller portion of the guide port 21 is smaller, ensuring that the conductive area between the smaller portion of the guide port 21 and the inlets remains constant. Meanwhile, the larger portion of the guide port 21 can more easily connect to both ports 121, and the conductive area with both ports 121 is relatively larger, meaning the flow regulation range with both ports 121 is also larger.

[0066] The second valve body 12 includes a radially spaced portion 123 and a plurality of circumferentially spaced portions 122. At least some interfaces 121 are provided between the radially spaced portions 123 and the circumferentially spaced portions 122, and each interface 121 is located on the same radial plane. The interfaces 121 arranged in this way have the same orientation, which helps to simplify the connection steps between each interface 121 and the other devices.

[0067] Please see Figure 4 and Figure 11 The valve core 2 includes a limiting hole wall 22, which may surround at least a portion of the limiting hole 23. The second valve body 12 has a limiting shaft 124, and the limiting shaft 124, the limiting hole 23, and the valve core 2 are coaxially arranged. At least a portion of the limiting shaft 124 is located within the limiting hole 23, and the limiting shaft 124 is radially limited by the limiting hole wall 22, that is, the limiting shaft 124 can restrict the radial movement of the valve core 2, thereby improving the coaxiality of the valve core 2.

[0068] It is important to understand that because the distance between the limiting shaft 124 and the limiting hole wall 22 is extremely small, air cannot escape from the limiting hole 23 during installation, thus affecting the installation of the valve core 2 and the second valve body 12. To solve this problem, a clearance groove 24 is provided in the limiting hole wall 22. The clearance groove 24 can communicate with the valve cavity 111. Therefore, when the valve core 2 and the second valve body 12 are installed, air in the limiting hole 23 can flow into the valve cavity 111 through the clearance groove 24, allowing the valve core 2 and the second valve body 12 to be installed normally. Furthermore, because the distance between the limiting shaft 124 and the limiting hole wall 22 is extremely small, as the valve core 2 rotates, friction will occur between the limiting shaft 124 and the limiting hole wall 22, which may generate debris. This debris will enter the clearance groove 24 as the valve core 2 rotates, thereby reducing or even eliminating the impact of debris on the rotation of the valve core 2.

[0069] Importantly, three or more interface areas 130 can be provided in the second valve body 12 according to actual needs. The number of interfaces 121 in each interface area 130 can be the same or different, and the circumferential angle occupied by each interface area 130 can be the same or different. For example, when there are three interface areas 130, the central angle of each interface area 130 can be the same, that is, 120°, or the central angle of each interface area 130 can be different. The specific central angle can be adjusted according to the actual situation. Correspondingly, three or more conduction areas 27 can be provided on the valve core 2, and each conduction area 27 corresponds to each interface area 130.

[0070] Please see Figure 2 , Figures 11 to 15It can be imagined that, since the interface 121 is located on the second valve body 12 and the through port 21 is located on the valve core 2, in order to prevent refrigerant cross-flow, a first sealing gasket 31 is provided between the second valve body 12 and the valve core 2. The first sealing gasket 31 is located on the side of the valve core 2 facing the second valve body 12. In order for the valve core 2 and the first sealing gasket 31 to be tightly abutted, an elastic element 4 is required to enhance the pressure of the valve core 2 squeezing the first sealing gasket 31.

[0071] Along the axial direction of the fluid control assembly, the elastic element 4 is located between the first valve body assembly 8 and the valve core assembly 9. The elastic element 4 abuts against the first valve body assembly 8 and the valve core assembly 9. The abutting area between the elastic element 4 and the first valve body assembly 8 is greater than the abutting area between the elastic element 4 and the valve core assembly 9.

[0072] It can be inferred that, since the contact area between the elastic element 4 and the first valve body assembly 8 is larger than the contact area between the elastic element 4 and the valve core assembly 9, the friction between the elastic element 4 and the first valve body assembly 8 is larger, while the friction between the elastic element 4 and the valve core assembly 9 is smaller. When the valve core assembly 9 rotates, the amount of rotation of the elastic element 4 following the rotation of the valve core assembly 9 can be reduced or prevented. Moreover, it is only necessary to overcome the small friction between the valve core assembly 9 and the elastic element 4 to drive the valve core assembly 9 to rotate, thus making it easier to drive the valve core assembly 9 to rotate.

[0073] The first valve body assembly 8 includes a first valve body 11 and a first wear-resistant structure 5. The first wear-resistant structure 5 is located between the first valve body 11 and the elastic member 4. The first wear-resistant structure 5 is fixed to the first valve body 11, and the elastic member 4 abuts against the first wear-resistant structure 5.

[0074] In the first technical solution, only the first wear-resistant structure 5 is provided. The first wear-resistant structure 5 can abut against the elastic element 4, thereby reducing the wear of the first valve body 11.

[0075] The valve core assembly 9 includes a valve core 4 and a second wear-resistant structure 6. The second wear-resistant structure 6 is located between the elastic element 4 and the valve core 2. The second wear-resistant structure 6 is fixed to the valve core 2, and the elastic element 4 abuts against the second wear-resistant structure 6.

[0076] In the second technical solution, only the second wear-resistant structure 6 is provided. The second wear-resistant structure 6 abuts against the elastic element 4, thereby reducing the wear of the valve core 2.

[0077] In the third technical solution, a first wear-resistant structure 5 and a second wear-resistant structure 6 can be provided simultaneously. The first wear-resistant structure 5 is fixed to the first valve body 11 and abuts against the elastic element 4, thereby reducing the wear of the first valve body 11. The second wear-resistant structure 6 is fixed to the valve core 4 and abuts against the elastic element 4, thereby reducing the wear of the valve core 2.

[0078] It is conceivable that during the operation of the fluid control assembly, the first valve body 11 remains stationary, and therefore the first wear-resistant structure 5 also remains stationary. When switching between different operating modes, the valve core 2 needs to rotate by a corresponding angle, so the second wear-resistant structure 6 may rotate along with the valve core 2. Since the contact area between the elastic element 4 and the first wear-resistant structure 5 is large, the friction between them will be relatively high. Similarly, since the contact area between the elastic element 4 and the second wear-resistant structure 6 is small, the friction between them will be relatively low. Therefore, when the valve core 2 rotates, it is difficult for it to drive the elastic element 4 to rotate as well; that is, the elastic element 4 and the first wear-resistant structure 5 remain relatively stationary, while the elastic element 4 and the second wear-resistant structure 6 rotate relative to each other.

[0079] It is conceivable that some existing fluid control components use bellows springs to enhance the sealing between the valve core 2 and the first sealing gasket 31. However, the contact area between the bellows spring and the valve core 2 and the first valve body 11 is the same, meaning the frictional force between the bellows spring and the valve core 2 and the first valve body 11 is basically the same. In this case, when the valve core 2 rotates, the bellows spring may rotate relative to both the valve core 2 and the first valve body 11. That is, there is frictional force between the bellows spring and both the valve core 2 and the first valve body 11. At this time, the controller 7 needs a larger torque to drive the valve core 2 to rotate. In this embodiment, since the elastic element 4 only rotates relative to the valve core 2, it is only necessary to overcome the frictional force between the elastic element 4 and the second wear-resistant structure 6 to drive the valve core 2 to rotate. Therefore, the controller 7 only needs a smaller torque to drive the valve core 2 to rotate.

[0080] Furthermore, in some existing fluid control components, the bellows spring may rotate relative to both the valve core 2 and the first valve body 11, thus generating noise between the bellows spring and both the valve core 2 and the first valve body 11. In this embodiment, however, since the elastic element 4 only rotates relative to the valve core 2, noise is only generated between the elastic element 4 and the second wear-resistant structure 6, resulting in relatively less noise.

[0081] The first wear-resistant structure 5 and the second wear-resistant structure 6 can be made of polytetrafluoroethylene (PTFE), which is stable and not easily worn.

[0082] The first valve body assembly 8 may include a first valve body 11, with the elastic element 4 abutting against the first valve body 11, and the valve core assembly 9 includes a valve core 2, with the elastic element 4 abutting against the valve core 2.

[0083] In the fourth technical solution, the elastic element 4 can directly abut against the first valve body 11, and the elastic element 4 can directly abut against the valve core 2. This method is simple to assemble and has a lower cost. The abutment area between the elastic element 4 and the first valve body 11 is larger than the abutment area between the elastic element 4 and the valve core 2. This technical effect is the same as that in the third technical solution, and will not be elaborated further here.

[0084] The elastic member 4 includes a connecting part 41 and an elastic part 42. The connecting part 41 and the elastic part 42 are fixed together. Along the axial direction of the elastic member 4, the elastic part 42 protrudes from the connecting part 41 toward the valve core assembly 9. The connecting part 41 abuts against the first valve body assembly 8, and the elastic part 42 abuts against the valve core assembly 9.

[0085] The elastic element 4 can be coaxially arranged with the valve core 2. At least two connecting portions 41 are provided, and each connecting portion 41 is spaced apart circumferentially, with the same circumferential angle between adjacent connecting portions 41. At least two elastic portions 42 are provided, and one elastic portion 42 is provided between adjacent connecting portions 41, with the same circumferential angle between adjacent elastic portions 42. It is conceivable that, since the angles between each elastic portion 42 are the same, the axial elastic force applied to the valve core 2 by each elastic portion 42 is the same, and the valve core 2 will not deviate relative to the axial direction, thus avoiding a situation where the valve core 2 is in close contact with the first sealing gasket 31 on one side, while the valve core 2 is in loose contact with the first sealing gasket 31 on the other side.

[0086] There can be four connecting parts 41 and four elastic parts 42, and the included angle between adjacent elastic parts 42 can be 90°.

[0087] The side of the connecting part 41 facing the first wear-resistant structure 5 can be a plane, that is, the connecting part 41 and the first wear-resistant structure 5 can be in surface contact, thereby increasing the contact area between the connecting part 41 and the first wear-resistant structure 5. Therefore, the friction between the connecting part 41 and the first wear-resistant structure 5 is greater and the stability is also better.

[0088] The elastic part 42 and the second wear-resistant structure 6 can be in line contact with each other, resulting in a small contact area. Alternatively, due to the deformation of the elastic part 42, they can be in surface contact. However, the surface contact area between the connecting part 41 and the first wear-resistant structure 5 is much larger than that between the elastic part 42 and the second wear-resistant structure 6. Therefore, the frictional force between the connecting part 41 and the first wear-resistant structure 5 is much greater than that between the elastic part 42 and the second wear-resistant structure 6. Consequently, the elastic element 4 can remain stationary with respect to the first valve body 11, while the elastic element 4 can rotate relative to the valve core 2.

[0089] Specifically, the elastic member 4 includes two inclined surfaces 422, one end of which is fixed to each other, and the other end of which is fixed to two connecting portions 41 respectively. The distance between the two inclined surfaces 422 gradually decreases along the direction away from the connecting portions 41. The two inclined surfaces 422 can be transitioned by a second arc portion 423, and / or the inclined surfaces 422 and the connecting portions 41 can be transitioned by a first arc portion 421.

[0090] To fix the elastic element 4 and prevent its radial movement. Please refer to [link / reference needed]. Figure 12 The inner wall surface of the first valve body 11 also includes a first limiting surface 113, and the valve core 2 includes a second limiting surface 26. The first limiting surface 113 is located radially outside the second limiting surface 26. At least a portion of the elastic element 4 is located between the first limiting surface 113 and the second limiting surface 26, and the elastic element 4 is radially limited by the first limiting surface 113 and the second limiting surface 26. That is, the first limiting surface 113 and the second limiting surface 26 can restrict the radial movement of the elastic element 4, thereby enhancing the installation stability of the elastic element 4.

[0091] The second valve body 12 is located on the side of the valve core 2 away from the elastic element 4, and the first sealing gasket 31 is located between the valve core 2 and the second valve body 12. Through the elastic deformation of the elastic element 4, the first sealing gasket 31 is clamped between the valve core 2 and the second valve body 12. Therefore, the elastic element 4 can enhance the pressure between the valve core 2 and the first sealing gasket 31, thereby enhancing the sealing performance between the valve core 2 and the first sealing gasket 31.

[0092] The first wear-resistant structure 5 can be integrally injection molded with the first valve body 11. This method can enhance the stability between the first wear-resistant structure 5 and the first valve body 11, thereby ensuring that the normal operation of the fluid control component will not be affected by the displacement of the first wear-resistant structure 5. Alternatively, the first wear-resistant structure 5 can be separately set from the first valve body 11. In this case, a groove 112 can be provided on the axial inner wall of the first valve body 11, and the first wear-resistant structure 5 can be fixed in the groove 112 by interference fit, snap-fit, bonding, or other methods.

[0093] The second wear-resistant structure 6 can be integrally injection molded with the valve core 2. This method enhances the stability between the second wear-resistant structure 6 and the valve core 2, preventing the second wear-resistant structure 6 from falling off when the valve core 2 rotates. Alternatively, the second wear-resistant structure 6 can be separately mounted from the valve core 2. It can be sleeved on the drive shaft of the valve core 2 and interference-fitted with the drive shaft. Or, the valve core 2 can have multiple limiting parts 25, arranged circumferentially around the central axis of the valve core 2, with the second wear-resistant structure 6 located radially inside the limiting parts 25 and interference-fitted with them. Alternatively, the valve core 2 may not need to have limiting parts 25; the second wear-resistant structure 6 can be bonded or snapped onto the valve core 2. It is important to understand that the limiting parts 25 can serve as mechanical limiting structures, abutting against the inner wall surface of the first valve body 11, thereby positioning the valve core 2 axially.

[0094] This technical solution also provides an elastic element 4, which includes a connecting portion 41 and an elastic portion 42 fixed to the connecting portion 41. Along the axial direction of the elastic element 4, the elastic element 4 is located between the first valve body assembly 8 and the valve core assembly 9, and the elastic element 4 abuts against the first valve body assembly 8 and the valve core assembly 9. The abutting area between the elastic element 4 and the first valve body assembly 8 is greater than the abutting area between the elastic element 4 and the valve core assembly 9.

[0095] Please see Figure 2 and Figure 3 The first sealing gasket 31 is provided with multiple air-proof holes 311, each air-proof hole 311 corresponding to each interface 121, thereby preventing cross-current in each interface 121.

[0096] Please see Figures 16 to 21 The second valve body 12 has a first mounting groove 125 on its side facing the first valve body 11. The first sealing gasket 31 includes a body portion 312, a sealing portion 313, and a mounting portion 314, which can be an integral structure. Specifically, the sealing portion 313 is fixed to the axial end face of the body portion 312 facing the valve core 2, and the sealing portion 313 can seal against the valve core 2.

[0097] Please see Figure 17 The radial width of the sealing part 313 is L1, and the radial width of the body part 312 is L2. The radial width of the sealing part 313 is smaller than that of the body part 312. Therefore, the sealing part 313 can be more easily deformed by the valve core 2, thus achieving a better sealing effect. Furthermore, due to the smaller radial width of the sealing part 313, even if the sealing part 313 is deformed by compression and expands radially, it will not exceed the radial boundary of the body part 312. In other words, the sealing part 313 will not affect the actual flow area of ​​the interface 121 due to its own expansion. In addition, the smaller radial width of the sealing part 313 results in a smaller contact area between the sealing part 313 and the valve core 2, thus reducing friction. When the valve core 2 rotates, it is less likely to drive the first sealing gasket 31 to rotate together.

[0098] The mounting part 314 is fixed to the axial end face of the main body 312 away from the valve core 2. The shape of the mounting part 314 is adapted to the shape of the first mounting groove 125, so the mounting part 314 can be disposed in the first mounting groove 125. It can be imagined that since the sealing part 313 abuts against the valve core 2, when the valve core 2 rotates, the valve core 2 will drive the first sealing gasket 31 to rotate together. Therefore, in order to prevent the first sealing gasket 31 from rotating, the inner wall of the first mounting groove 125 can abut against the mounting part 314, thereby restricting the rotation of the first sealing gasket 31.

[0099] A portion of the first mounting groove 125 may be located within the circumferential spacing portion 122 and the radial spacing portion 123, that is, a portion of the first sealing gasket 31 is located within the circumferential spacing portion 122 and the radial spacing portion 123.

[0100] To further prevent the valve core 2 from driving the first sealing gasket 31 to rotate, a limiting block 126 can be provided on the circumferential side of the circumferential spacing portion 122. The axial height of the limiting block 126 can be slightly greater than the axial height of the circumferential spacing portion 122. In this case, the limiting block 126 can abut against the circumferential side of the body portion 312, thereby restricting the circumferential movement of the first sealing gasket 31. Similarly, a limiting block 126 can also be provided on the radial side of the radial spacing portion 123. The axial height of the limiting block 126 can be slightly greater than the axial height of the radial spacing portion 123. The limiting block 126 can abut against the radial side of the body portion 312, thereby restricting the radial movement of the first sealing gasket 31.

[0101] It should be noted that during normal operation of the fluid control assembly, the valve core 2 and the limit block 126 are kept at a distance.

[0102] To further prevent the valve core 2 from rotating the first sealing gasket 31, the second valve body 12 also includes a positioning post 127. The positioning post 127 can be located in the first mounting groove 125 and can be arranged axially. Correspondingly, the first sealing gasket 31 has a positioning hole 315 on its axial end face away from the valve core 2, and at least part of the positioning post 127 is located in the positioning hole 315. The positioning post 127 and the inner wall of the positioning hole 315 can be radially limited, that is, the inner wall of the positioning hole 315 can restrict the radial movement of the positioning post 127, thereby restricting the radial movement of the first sealing gasket 31.

[0103] The second valve body 12 is further provided with a second mounting groove 128 on its axial end face facing the first valve body 11. The second mounting groove 128 may be located radially outside the first mounting groove 125. A second sealing ring 34 may be disposed in the second mounting groove 128, and the second sealing ring 34 may abut against the axial end face of the first valve body 11, thereby enhancing the sealing performance between the first valve body 11 and the second valve body 12.

[0104] The second valve body 12 is also provided with a third mounting groove 129 on the axial end face away from the first valve body 11. At least part of the second sealing gasket 32 ​​can be set in the third mounting groove 129. After the second valve body 12 is fixed to the external equipment, the second sealing gasket 32 ​​can abut against the external equipment, thereby enhancing the sealing between the second valve body 12 and the external equipment.

[0105] It is important to understand that the fluid control component provided in this technical solution can independently achieve the function of guiding fluid flow; that is, the first valve body 11 and the second valve body 12 can be directly fixed to other thermal management components and guide fluid flow. Alternatively, the fluid control component can be integrated with other fluid components to jointly achieve the function of guiding fluid flow. Specifically, the first valve body 11 and the second valve body 12 can be integrated with other valve bodies to form a flow channel plate, or the flow channel plate can be a single integrated structure with multiple valve bodies. The flow channel plate is then fixed to other thermal management components and guides fluid flow. Multiple valve bodies can be integrated on the flow channel plate, and flow channels can be provided between each valve body. These flow channels can guide different valve bodies to achieve different operating modes.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and controls without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
