DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0031] Reference Figure 1 and Figure 2 The valve component 10 can be applied to a vehicle thermal management system or an air-conditioning system, and in particular can be applied to a circulation system of a high-pressure fluid such as a refrigerant, wherein the vehicle thermal management system includes a new energy vehicle thermal management system, and here the new energy vehicle thermal management system is taken as an example.

[0032] Reference Figure 1-Figure 3 This embodiment discloses a valve component 10 that can be installed by insertion. The valve component 10 includes a drive component, a housing assembly 102 and a valve core 101. The drive component is located at least partially around the periphery of the valve core 101. The drive component is fixedly connected or limited to the housing assembly 102, and is electrically and / or signally connected to the outside world through the drive component. Furthermore, a seal can be provided between the drive component and the housing assembly 102 to prevent water vapor or other impurities in the external environment from entering through the assembly gap. Under the action of the drive component, the valve core 101 can move to switch / convert the valve port.

[0033] The shell assembly 102 has a first cavity 102a, at least a portion of the valve core 101 is located in the first cavity 102a, the valve component 10 includes an adjustment assembly 110, the adjustment assembly 110 includes an adjustment seat 11, the shell assembly 102 includes a first opening portion 111, at least a portion of the adjustment seat 11 is located in the first opening portion 111, the first opening portion 111 has a first opening 111a on the second outer side wall 1021b of the shell assembly 102, and the relative position of the adjustment seat 11 and the shell assembly 102 is adjustable along the opening direction of the first opening 111a.

[0034] When the valve component 10 is installed on the mounting portion 20, the plug-in structure can achieve a quick installation effect and improve the integration. In order to improve the sealing between the valve component 10 and the outside and reduce the probability of fluid leakage from the assembly gap. Since the assembly gap is fixed, under normal assembly gap, it is difficult for the first sealing portion 115 installed in the assembly gap to achieve the required sealing effect. When the assembly gap is reduced, when the valve component 10 is installed on the mounting portion 20, the first sealing portion 115 is squeezed, which easily causes the first sealing portion 115 to deform or even fail. The relative position of the adjustment seat 11 and the housing assembly 102 is adjustable. The first sealing portion 115 can be installed between the adjustment seat 11 and the mounting portion 20. After the valve component 10 is installed on the mounting portion 20, the position of the adjustment seat 11 is adjusted to ensure that the adjustment seat 11 and the mounting portion 20 can press the first sealing portion 115.

[0035] The mounting portion 20 here can be an integrated component or a flow channel plate or other components that can be installed on the plug-in valve body. The first sealing portion 115 can be pre-installed on the adjustment seat 11, or can be pre-installed on the mounting portion 20, or can even be an independent component that is assembled together during assembly. The position of the adjustment seat 11 can be adjusted so that the first sealing portion 115 is pressed tightly. The position of the first sealing portion 115 is not limited here.

[0036] Reference Figure 2-Figure 9Specifically, the housing assembly 102 includes a second outer side wall 1021b, the second outer side wall 1021b is located at at least one side of the housing assembly 102, and the first opening portion 111 is concave relative to the second outer side wall 1021b. The first opening portion 111 has at least two openings, that is, the first opening portion 111 has a first opening 111a and a second opening 112a, the housing assembly 102 has a first opening 111a on the second outer side wall 1021b, the housing assembly 102 has a second opening 112a on the wall surface forming the first cavity 102a, the second opening 112a is connected to the first cavity 102a, and the first opening 111a and the second opening 112a include the wall surface defining the first opening portion 111. At least part of the adjustment seat 11 is located in the cavity defined by the first opening portion 111. Along the opening direction of the first opening 111a, the relative position of the adjustment seat 11 relative to the first opening portion 111 is adjustable, that is, in at least one state, the adjustment seat 11 is completely located in the cavity defined by the first opening portion 111. In at least another state, the adjustment seat 11 can be adjusted to compress the first sealing portion 115.

[0037] The housing assembly 102 includes a first step portion 113. Specifically, the first step portion 113 forms a part of the wall of the first opening portion 111. The direction perpendicular to the axis of the valve core 101 is defined as a reference direction. With the reference direction as the axis, the first step portion 113 is annularly surrounded or spaced to form a plurality of second openings 112a. The diameter of the second opening 112a is smaller than the diameter of the first opening 111a. Along the opening direction of the second opening 112a, the first step portion 113 is located between the adjustment seat 11 and the valve core 101. The position of the adjustment seat 11 relative to the housing assembly 102 is adjustable. The housing assembly 102 includes a first structural state and a second structural state. In the first structural state, along the reference direction, the adjustment seat 11 abuts against the first step portion 113 to limit the position of the adjustment seat 11. In the second structural state, relative to the position of the adjustment seat 11 in the first structural state, the adjustment seat 11 is away from the valve core 101. Along the reference direction, there is a gap between the adjustment seat 11 and the first step portion 113.

[0038] The housing assembly 102 includes a second step portion 114, which is located between the first opening 111a and the second opening 112a along the reference direction. The diameter of the channel formed by the second step portion 114 is greater than the diameter of the channel formed by the first step portion 113 along the radial direction of the adjustment seat 11. At least part of the adjustment seat 11 is located between the first step portion 113 and the second step portion 114 along the reference direction. The fluid subassembly 100 includes a second sealing portion 116, which is located between the adjustment seat 11 and the second step portion 114 along the radial direction of the adjustment seat 11. When the two sides of the first sealing portion 115 abut against the first side wall 2011 and the adjustment seat 11 respectively, that is, in the second structural state, within the movement range of the adjustment seat 11, along the radial direction of the adjustment seat 11, one side of the second sealing portion 116 abuts against the second step portion 114, and the other side of the second sealing portion 116 abuts against the adjustment seat 11. Similarly, in the first structural state, one side of the second sealing portion 116 abuts against the second step portion 114, and the other side of the second sealing portion 116 abuts against the adjustment seat 11. The second sealing portion 116 can seal the gap between the adjustment seat 11 and the first opening 111, whether in the second structural state or the first structural state, to reduce leakage.

[0039] In some embodiments, the adjustment seat 11 has a second channel 11a, one side of the second channel 11a can be connected to the first cavity 102a, and the other side of the second channel 11a has an opening on the end wall of the adjustment seat 11. After the adjustment seat 11 presses the first sealing portion 115, the first sealing portion 115 surrounds the second channel 11a to reduce the leakage of the fluid from the second channel 11a. In order to reduce the flow resistance, the caliber of the second opening 112a is smaller than the caliber of the second channel 11a of the adjustment seat 11. In other embodiments, the adjustment seat 11 may not have a channel, so that in the first structural state, the adjustment seat 11 and the mounting portion 20 can clamp the first sealing portion 115, and the leakage can be reduced within the sealing range of the first sealing portion 115. The first sealing portion 115 can be located only on one side wall of the housing assembly 102, or it can surround the outer peripheral wall of the housing assembly 102. The specific structure of the first sealing portion 115 is not limited here.

[0040] The adjustment seat 11 is connected to the first opening 111. After the valve component 10 and the mounting portion 20 are assembled, how to adjust the position of the adjustment seat 11 becomes a technical problem to be solved. The movable connection between the adjustment seat 11 and the first opening 111 here needs to achieve the purpose of adjustment, so it can be a threaded connection or a retaining spring limiter, including but not limited to the above connection methods. In the second structural state, the first sealing portion 115 can seal the leakage gap between the second channel 11a and the fluid sub-assembly 100 and the mounting portion 20. The connection method between the adjustment seat 11 and the housing assembly 102 can include the following implementations:

[0041] Refer to 4 and Figure 5 In one embodiment, the housing assembly 102 includes a first inner wall 1111, the outer wall of the adjustment seat 11 has a first threaded segment 121, the first opening portion 111 has a second threaded segment 122, the second threaded segment 122 is away from the valve core 101 relative to the first inner wall 1111, one of the first threaded segment 121 and the second threaded segment 122 can be an internal thread, and the other can be an external thread, and it is only necessary to achieve the effect of thread matching, and the first threaded segment 121 and the second threaded segment 122 are not restricted here.

[0042] In the first structural state, in order to reduce the damage to the first sealing part 115 during the assembly process, when the first sealing part 115 is pre-assembled with the adjustment seat 11, the adjustment seat 11 and the first sealing part 115 are located in the cavity of the first opening 111, or the housing component 102 and the wall of the accommodating cavity 201 have a sufficient installation gap so that the first sealing part 115 will not be squeezed during the assembly process. Therefore, in the process of assembling the fluid control component 1, in theory, when the housing component 102 is installed along the opening direction of the accommodating cavity 201, the first sealing part 115 will not be squeezed and deformed by the installation part 20. Therefore, the design of the adjustment seat 11 effectively reduces the probability of failure of the first sealing part 115 and improves the reliability of the sealing performance of the first sealing part 115.

[0043] With the first thread segment 121 and the second thread segment 122 threadedly matched, the adjustment seat 11 is rotated, and along the opening direction of the first opening portion 111, the adjustment seat 11 can be adjusted to a desired position relative to the first opening portion 111, and after the adjustment seat 11 is adjusted to the first position, the adjustment seat 11 can make the first sealing portion 115 press against the first side wall 2011 of the accommodating cavity 201.

[0044] The adjusting seat 11 and the first opening portion 111 are connected by threaded matching. On the one hand, the technology for processing the thread is mature, the processing method is relatively simple, and the operability is strong; on the other hand, by the threaded matching adjusting seat 11 and the first opening portion 111, the adjusting seat 11 is rotated to the first position, and the interaction between the first thread segment 121 and the second thread segment 122 can make the adjusting seat 11 and the mounting portion 20 clamp the first sealing portion 115, and can continue to maintain the second structural state. Compared with the valve component 10 assembled in a general manner, the gap between the adjusting seat 11 and the first side wall 2011 can be adjusted to a smaller size, thereby clamping the first sealing portion 115, which is conducive to improving the sealing effect and reducing leakage. Similarly, the first sealing portion 115 here can be pre-assembled with the adjusting seat 11, or pre-assembled with the mounting portion 20 or be an independent component. The accompanying drawings only show the structure of the first sealing portion 115 pre-installed with the adjusting seat 11 under this embodiment, which actually includes but is not limited to the above structure.

[0045] Specifically, the adjustment assembly 110 includes a force-applying portion 123, which is convex or concave relative to the wall of the second channel 11a of the adjustment seat 11. When the operator adjusts the position of the adjustment seat 11, the adjustment of the adjustment seat 11 is achieved by applying force through the force-applying portion 123. The design of the force-applying portion 123 here greatly improves the convenience of the operator's implementation. In this embodiment, the force-applying portion 123 extends radially from the wall of the second channel 11a and is connected to the first side wall 2011 of the second channel 11a in a "straight" shape. In other embodiments, the force-applying portion 123 can also be a structure that is concave relative to the wall of the second channel 11a, and it only needs to be convenient for the operator to apply force. The structure of the force-applying portion 123 is not limited here.

[0046] Reference Figure 6-Figure 8 In another embodiment, the adjustment component 110 includes an elastic member 131 and a limit member 132. The elastic member 131 and the limit member 132 are located in the cavity formed by the first opening portion 111. Along the opening direction of the first opening 111, one side of the elastic member 131 abuts against the first step portion 113, and the other side of the elastic member 131 abuts against the adjustment seat 11. Along the reference direction, the elastic member 131 can apply a force on the adjustment seat 11 away from the side of the valve core 101. The adjustment seat 11 can make the first sealing portion 115 abut against the first side wall 2011 of the accommodating cavity 201, so that the adjustment seat 11 and the first side wall 2011 clamp the first sealing portion 115, which is beneficial to improve the sealing effect and reduce leakage.

[0047] Specifically, the adjustment seat 11 has a mounting groove 133, the mounting groove 133 is used to accommodate the elastic member 131, the mounting groove 133 is axially opened by one end of the adjustment seat 11, and the mounting groove 133 is connected to the second channel 11a, the adjustment seat 11 forms a step for abutting and fixing the elastic member 131, the elastic member 131 surrounds the second channel 11a, and one side of the elastic member 131 abuts the first step portion 113, and the other side of the elastic member 131 abuts the adjustment seat 11. The housing assembly 102 includes a limiting portion 134, and in some embodiments, the limiting portion 134 can be a groove recessed in the inner wall of the first opening portion 111, for installing the limiting member 132. When the fluid sub-assembly 100 is in the second structural state, part of the limit member 132 is located in the cavity formed by the limit portion 134, and one side of the limit member 132 abuts against the adjustment seat 11, and the other side abuts against the limit portion 134, so as to ensure that the adjustment seat 11 is located in the cavity defined by the first opening portion 111, which is beneficial to reduce the wear on the first sealing portion 115 during the assembly of the fluid sub-assembly 100 and the mounting portion 20.

[0048] After assembly, the stopper 132 is removed, and the elastic member 131 applies a spring force to the adjusting seat 11 away from the side of the valve core 101, so that the adjusting seat 11 can make the first sealing portion 115 press against the first side wall 2011 of the accommodating chamber 201, forming a second structural state to reduce the leakage of the fluid. Similarly, the first sealing portion 115 here can be pre-assembled with the adjusting seat 11, or pre-assembled with the mounting portion 20 or be an independent component. The accompanying drawings only show the structure of the first sealing portion 115 and the mounting portion 20 pre-assembled in this embodiment, which actually includes but is not limited to the above structure.

[0049] In this embodiment, the limiting member 132 may be a retaining spring, and the limiting portion 134 may be a protrusion or a concave structure relative to the wall of the first opening portion 111. The drawings only show that the limiting portion 134 is a concave feature, and the actual structure includes but is not limited to the above structure.

[0050] Reference Figure 4 and Fig. 9 Specifically, the valve component 10 also includes a sealing seat 1022 and a sealing cover 1023 .

[0051] The sealing seats 1022 include at least two. In the present embodiment, the two sealing seats 1022 are located on both sides of the valve core 101. The sealing seats 1022 are provided with an arc-shaped surface matching with the outer surface of the valve core 101. At least part of the outer surface of the valve core 101 is tightly fitted with the arc-shaped surface of the sealing seats 1022. With the cooperation of the cover 1023 and the shell assembly 102, the sealing seats 1022 radially support and seal the valve core 101. Under the action of the driving component, the valve core 101 can rotate relative to the sealing seat 1022 with the axis of the fluid sub-assembly 100 as the axis.

[0052] The housing assembly 102 includes a second opening portion 112, and the second opening portion 112 has a third opening 112a on the side wall of the housing assembly 102, and the third opening 112a can communicate with the first cavity 102a. The first opening 111a and the third opening 112a are located on the two side walls of the housing assembly 102 facing away from each other. At least a portion of the cover 1023 is located at the third opening 112a, and the cover 1023 is connected to the second opening portion 112. The connection here can be a threaded connection or welding for the purpose of preventing loosening. In this embodiment, the cover 1023 is threadedly connected to the wall of the second opening portion 112 to form a detachable connection. In other embodiments, the cover 1023 and the second opening portion 112 can also be connected in other ways.

[0053] Furthermore, the cover 1023 has a second cavity 1023a, and the second cavity 1023a has an opening on the side wall of the cover 1023, which is used to accommodate and limit at least part of the sealing seat 1022. At least part of one of the sealing seats 1022 is located in the second cavity 1023a, and along the opening direction of the second opening portion 112, the valve core 101 and the cover 1023 clamp the sealing seat 1022. During the installation of the cover 1023, the sealing seat 1022 on one side of the valve core 101 is limited by the cover 1023, and the sealing seat 1022 on the other side of the valve core 101 is limited by the first step portion 113. The two sealing seats 1022 abut against the surface of the valve core 101 to support and seal the valve core 101. In this embodiment, the sealing seat 1022 is arranged in an annular shape to ensure the passage of fluid while supporting the valve core 101.

[0054] Reference Figure 1 and Figure 4 In order to reduce leakage, a third sealing portion 117 is provided between the sealing seat 1022 on one side of the valve core 101 and the cover 1023, and a third sealing portion 117 is also provided between the sealing seat 1022 on the other side of the valve core 101 and the housing assembly 102. The fluid subassembly 100 includes a valve closing state and a valve opening state. In the valve closing state, the channel 101a of the valve core 101 is not connected to any second channel 11a, or the channel 101a of the valve core 101 is only connected to the second channel 11a as the inlet channel, and the fluid cannot be discharged from the outlet channel, so the internal pressure of the first chamber 102a increases. The provision of the third sealing portion 117 can reduce the probability of fluid leakage from the sealing seat 1022 and the housing assembly 102 and / or the cover 1023, which is conducive to reducing leakage. In this embodiment, at least two second channels 11a are provided, at least one of which is used as an inlet channel, and at least another one of which is used as an outlet channel.

[0056] The fluid subassembly 100 includes at least one of a shell assembly 102 and a mounting portion 20. In the present embodiment, the fluid subassembly 100 may be the mounting portion 20, the shell assembly 102 of the valve component 10, or the mounting portion 20 and the shell assembly 102. No limitation is made here.

[0057] The fluid control assembly 1 includes a first structural state. According to the movable connection relationship between the adjustment seat 11, the housing assembly 102 and the mounting portion 20, in the first structural state: the first sealing portion 115 is located between one of the adjustment seats 11 and the side wall defining the accommodating cavity 201 or the outer side wall of the housing assembly 102 or another adjustment seat 11; wherein the adjustment seat 11 can move toward or away from the side wall defining the accommodating cavity 201 to adjust the clamping state of the first sealing portion 115. By enabling the adjustment seat 11 to move to adjust the clamping state of the first sealing portion 115, the probability of fluid leakage from between the valve component 10 and the mounting portion 20 is reduced, which is conducive to reducing leakage.

[0058] Reference Fig.10 , Figure 15-17The first sealing portion 115 is located between the wall defining the accommodating chamber 201 and the adjusting seat 11. The adjusting seat 11 can move to adjust the clamping state of the first sealing portion 115, thereby reducing the probability of fluid leakage from between the valve component 10 and the mounting portion 20, which is beneficial to reducing leakage. In addition, when assembling the fluid sub-assembly 100, the position of the adjusting seat 11 is pre-adjusted, and the valve component 10 is installed from the opening of the accommodating chamber 201. There is a gap between the first sealing portion 115 and the wall of the mounting portion 20 or one of the walls of the housing assembly 102. Adjust the position of the adjustment seat 11 until the adjustment seat 11 and the mounting part 20 / shell assembly 102 press the first sealing part 115. When the fluid sub-assembly 100 is installed from the opening of the accommodating cavity 201, since there is a gap between the first sealing part 115 and the wall of the mounting part 20 / shell assembly 102, the first sealing part 115 will not be subjected to radial compression and will not be squeezed and deformed. After the fluid sub-assembly 100 and the mounting part 20 are installed and fixed, adjust the position of the adjustment seat 11 to ensure that the adjustment seat 11 and the mounting part 20 press the first sealing part 115, which is beneficial to improve the sealing performance of the first sealing part 115.

[0059] The housing assembly 102 includes a second outer side wall 1021 b , and the accommodating cavity 201 has a first side wall 2011 , and the first side wall 2011 is at least partially disposed opposite to the second outer side wall 1021 b .

[0060] Reference Fig.11 and Fig.15 The fluid subassembly 100 includes a first step portion 113. Since the fluid subassembly 100 includes at least one of the mounting portion 20 and the housing assembly 102, the first step portion 113 is located at the mounting portion 20 and / or the housing assembly 102. Optionally, in the first structural state, the first sealing portion 115 is recessed into the second outer side wall 1021b. Along the rotation direction perpendicular to the valve core 101, the adjustment seat 11 abuts against the first step portion 113 to limit the position of the adjustment seat 11 in the first structural state, thereby playing a positioning role.

[0061] The fluid subassembly 100 includes a second step portion 114, the second step portion 114 includes a first inner wall 1111, the first inner wall 1111 is away from the valve core 101 relative to the first step portion 113, and the second step portion 114 is expanded relative to the first step portion 113 along the radial direction of the adjustment seat 11, and at least part of the adjustment seat 11 is located between the first step portion 113 and the second step portion 114. The fluid subassembly 100 includes a second sealing portion 116, the second sealing portion 116 is located between the adjustment seat 11 and the first inner wall 1111, and along the radial direction of the adjustment seat 11, one side of the second sealing portion 116 abuts against the adjustment seat 11, and the other side of the second sealing portion 116 abuts against the first inner wall 1111. In the second structural state, within the moving stroke range of the adjustment seat, along the radial direction of the adjustment seat 11, one side of the second sealing portion 116 abuts against the first inner wall 1111, and the other side of the second sealing portion 116 abuts against the adjustment seat 11. Similarly, in the first structural state, one side of the second sealing portion 116 abuts against the first inner wall 1111, and the other side of the second sealing portion 116 abuts against the adjustment seat 11. The second sealing portion 116 can seal the gap between the adjustment seat 11 and the first opening 111, whether in the second structural state or the first structural state, to reduce leakage.

[0062] In some embodiments, the mounting portion 20 has a first channel 2012, the second channel 11a is in communication with at least a portion of the first channel 2012, the first channel 2012 has an opening in the wall defining the accommodating cavity 201, and the first sealing portion 115 surrounds the first channel 2012. The first sealing portion 115 surrounds the first channel 2012, and can seal the periphery of the first channel 2012, which is beneficial to reduce leakage.

[0063] Reference Fig.11 There is an assembly gap between the housing assembly 102 and the mounting portion 20. In order to reduce leakage in the existing solution, a first sealing portion 115 needs to be provided in the assembly gap between the two, and the first sealing portion 115 needs to be pressed tightly against the adjustment seat 11 and the housing assembly 102 / mounting portion 20 to minimize leakage. However, when the valve component 10 is installed from the opening of the accommodating cavity 201 to the mounting portion 20, since the assembly gap between the mounting portion 20 and the valve component 10 is very small, the first sealing portion 115 will be radially squeezed, or even cut by the side wall of the accommodating cavity 201 and fail, for example Figure 7 When the side wall of the accommodating cavity 201 is provided with a first channel 2012 , the first sealing portion 115 at the end of the first channel 2012 opening on the inner side wall is prone to form a sharp intersecting edge, which leaves a safety hazard for the installation of the first sealing portion 115 .

[0064] The fluidic subassembly 100 includes a first structural state and a second structural state.

[0065] There are many implementation methods, with three examples as examples:

[0066] Reference Fig.12 , Figure 15-17 When the adjustment seat 11 is located in the housing assembly 102, the first opening 111 is opened inwardly from the second outer side wall 1021b. In the first structural state, along the opening direction of the first opening 111a, there is a gap between the first sealing portion 115 and the first side wall 2011. When the pre-assembled housing assembly 102, the adjustment seat 11 and the mounting portion 20 are assembled, there is a gap between the first sealing portion 115 and the first side wall 2011, which reduces the contact friction between the first sealing portion 115 and the mounting portion 20 during the assembly process, which is conducive to reducing the loss of the first sealing portion 115;

[0067] Reference Fig.13 When the adjustment seat 11 is located at the mounting portion 20, the first opening portion 111 is opened inwardly from the wall defining the accommodating cavity 201. In the first structural state, along the opening direction of the first opening 111a, there is a gap between the first sealing portion 115 and the second outer side wall 1021b. When the pre-assembled housing assembly 102, the adjustment seat 11 and the mounting portion 20 are assembled, the housing assembly 102 can avoid the first sealing portion 115, thereby reducing the contact friction between the first sealing portion 115 and the mounting portion 20 during the assembly process, which is conducive to reducing the loss of the first sealing portion 115.

[0068] When there are more than two adjustment seats 11, two are taken as an example, one of the adjustment seats 11 is located in the housing assembly 102, and the other is located in the mounting portion 20, in the first structural state, there is a gap between the first sealing portion 115 and at least one of the two adjustment seats 11. When the pre-assembled housing assembly 102, the adjustment seat 11 and the mounting portion 20 are assembled, the contact friction between the first sealing portion 115 and the two adjustment seats 11 is reduced, which is conducive to reducing the loss of the first sealing portion 115.

[0069] It should be noted that the first sealing portion 115 here can be pre-installed on one of the adjustment seat 11, the installation portion 20, and the housing assembly 102, which actually includes but is not limited to the above-mentioned embodiments.

[0070] At least part of the adjustment seat 11 is located at the first opening 111, and the position is adjustable. Along the opening direction of the first opening 111a, the position of the adjustment seat 11 is adjusted to the first structural state. When the valve component 10 and the mounting portion 20 are assembled, the first side wall 2011 and the second outer side wall 1021b can have a larger assembly gap. On the one hand, during the process of installing the valve component 10 to the opening side of the accommodating cavity 201, the probability of the first sealing portion 115 and the mounting portion 20 or the housing assembly 102 or the adjustment seat 11 being squeezed and deformed is reduced, which is conducive to extending the service life of the first sealing portion 115; on the other hand, compared with the existing solution, the adjustment seat 11 has lower processing accuracy requirements for the mounting portion 20 and the housing assembly 102, which is conducive to reducing costs.

[0071] When the valve component 10 is installed from the opening of the accommodating cavity 201, since there is a gap between the adjusting seat 11 and the first side wall 2011 of the mounting portion 20, the first sealing portion 115 will not be subjected to radial extrusion and thus will not be squeezed and deformed. After the fluid sub-assembly 100 and the mounting portion 20 are installed and fixed, the position of the adjusting seat 11 is adjusted. The adjusting seat 11 and the mounting portion 20 can press the first sealing portion 115, which is beneficial to improving the sealing performance of the first sealing portion 115.

[0072] Reference Figure 8 , Figure 10-12 Specifically, the first sealing portion 115 can be connected to one of the mounting portion 20 and the housing assembly 102, or can be a separate component, and only needs to be able to surround the second channel 11a and the first channel 2012 and the leakage gap between the sealing mounting portion 20 and the adjustment seat 11 during assembly. Preferred embodiments include the following:

[0073] Reference Fig.12 , Fig.15 and Fig.16 In one embodiment, the fluid control component 1 includes a matching portion 1161, which is located at the end of the adjustment seat 11, along the opening direction of the first opening portion 111, and the end is located on the side of the adjustment seat 11 away from the valve core 101, for accommodating and installing at least part of the first sealing portion 115. In this embodiment, the matching portion 1161 can be a groove with an inwardly concave arrangement, and the matching portion 1161 surrounds the second channel 11a. Along the opening direction of the first opening 111a, at least part of the first sealing portion 115 is embedded in the groove. It should be noted that at least part of the first sealing portion 115 needs to protrude from the groove. When the adjustment seat 11 is adjusted to the first position, the adjustment seat 11 and the first side wall 2011 of the accommodating cavity 201 can press the first sealing portion 115 to reduce the leakage of the fluid from the assembly gap. Setting the first sealing portion 115 at the end of the adjustment seat 11 is conducive to the early assembly and positioning of the first sealing portion 115, thereby improving the effectiveness of the first sealing portion 115;

[0074] Reference Fig.11 , Figure 15-17 In another embodiment, the fluid control assembly 1 includes a matching portion 1161, which is located at the mounting portion 20 and is used to accommodate and install at least a portion of the first sealing portion 115. In this embodiment, the matching portion 1161 may be a groove, and the matching portion 1161 may be located at one of the housing assembly 102, the mounting portion 20, and the adjustment seat 11. For example, in one embodiment, along the opening direction of the first opening 111a, the matching portion 1161 is opened inwardly from the first side wall 2011 of the accommodating cavity 201, and the matching portion 1161 is concave relative to the first side wall 2011, and the matching portion 1161 surrounds the first channel 2012. Along the opening direction of the first opening 111a, at least a portion of the first sealing portion 115 is embedded in the groove. It should be noted that at least a portion of the first sealing portion 115 needs to protrude from the groove. When the adjustment seat 11 is adjusted to the first position, the adjustment seat 11 and the first side wall 2011 of the accommodating cavity 201 can press the first sealing portion 115 to reduce the leakage of the fluid from the assembly gap.

[0075] In another embodiment, the first sealing portion 115 is an independent component that does not need to be pre-assembled on the mounting portion 20 or the adjustment seat 11. When the mounting portion 20 and the fluid subassembly 100 are assembled, in order to reduce the wear on the first sealing portion 115, a larger gap, i.e., an assembly gap, can be reserved between the second outer side wall 1021b and the first side wall 2011 of the accommodating chamber 201. Optionally, the gap is greater than the thickness of the first sealing portion 115, where the thickness refers to the size of the first sealing portion 115 in the opening direction of the first opening 111a. When the mounting portion 20 and the fluid subassembly 100 are assembled, the first sealing portion 115 can be pre-placed in the accommodating chamber 201 near the first side wall 2011. When the adjustment seat 11 is adjusted to the first position, the adjustment seat 11 and the first side wall 2011 of the accommodating chamber 201 can press the first sealing portion 115 to reduce the leakage of the fluid from the assembly gap.

[0076] In practice, it includes but is not limited to the above-mentioned embodiments. After the assembly is completed, the first sealing portion 115 can still be pressed by the adjusting seat 11 to seal the assembly gap between the fluid subassembly 100 and the mounting seat. It should be noted that the fluid subassembly 100 includes a first structural state and a second structural state. The first position here does not refer to a completely fixed position. When the second channel 11a and the assembly gap are in the desired ideal second structural state, the position of the adjusting seat 11 is the first position. The first position here allows fluctuations within a certain range. In the ideal second structural state, the fluid leakage of the fluid subassembly 100 is also within the allowable range.

[0077] Reference Fig.11 , Fig.13 and Fig.18 This embodiment also discloses a method for assembling a fluid control assembly 1, including the fluid control assembly 1 described in any of the above embodiments, and the assembling steps include:

[0080] The position of the adjustment seat 11 is adjusted until the adjustment seat 11 presses the first sealing portion 115 into the second state, wherein the deformation degree of the first sealing portion 115 in the second state is greater than the deformation degree of the first sealing portion 115 in the first state.

[0081] It should be noted that the first state here refers to the state of the first sealing part 115 before the valve component 10 and the mounting part 20 are assembled or preliminarily assembled. In the first state, the first sealing part 115 is in the initial state or slightly compressed, and is located between one of the adjustment seats 11 and the mounting part 20 or the housing assembly 102 or another of the adjustment seats 11; after adjusting the position of the adjustment seat 11, the first sealing part 115 changes from the first state to the second state, and the deformation degree of the first sealing part 115 in the second state is greater than the deformation degree of the first sealing part 115 in the first state, that is, the first sealing part 115 is assembled in the first state, which can effectively reduce the damage to the first sealing part 115; by adjusting the position of the adjustment seat 11, the clamping degree of the first sealing part 115 is adjusted to achieve a better sealing effect. The initial state here refers to the state in which the first sealing part 115 is not squeezed by the adjustment seat 11 and the mounting part 20 or the housing assembly 102 or another of the adjustment seats 11.

[0082] In some embodiments, before assembling the adjustment seat 11, the first sealing portion 115 can be assembled to the installation space corresponding to the adjustment seat 11, and the adjustment seat 11 and the first sealing portion 115 can be assembled as an integral structure. Alternatively, the first sealing portion 115 can also be installed in the accommodating cavity first, and then the adjustment seat 11 can be assembled.

[0088] The adjusting seat 11 is spirally rotated in the reverse direction to move the adjusting seat 11 outward relative to the first opening 111 until the adjusting seat 11 and the mounting portion 20 or the housing assembly 102 or the adjusting seat 11 press the first sealing portion 115 into the second state.

[0089] In another embodiment, the assembling step comprises:

[0090] The adjusting seat 11 is assembled with at least one of the housing assembly 102 and the mounting portion 20 of the valve member 10. The first sealing portion 115 can be pre-assembled to the adjusting seat 11. At this time, the first sealing portion 115 forms a first state. The adjusting seat 11 is pressed into the first opening 111a of the first opening portion 111, and the limiting member 132 is clamped and fixed with the limiting portion 134. The adjusting seat 11 is limited by the limiting member 132.

[0091] The mounting portion 20 has a receiving cavity 201, and the assembled fluid subassembly 100 is fixed to the mounting portion 20, so that the first sealing portion 115 is located between one of the adjustment seats 11 and the mounting portion 20 or the housing assembly 102 or another of the adjustment seats 11 in a first state;

[0092] The limiting member 132 is removed, and the adjusting seat 11 is reset under the action of the elastic member 131 until the adjusting seat 11 and the mounting portion 20 or the housing assembly 102 or the adjusting seat 11 press the first sealing portion 115 tightly.

[0093] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail in this specification with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
