[0032] The following will describe in detail some embodiments of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] In view of the above problems, an embodiment of the present utility model provides a regulating valve. Please refer to Figure 1 and Figure 2 , which includes a solenoid valve assembly 10 and a check valve assembly 20.

[0034] The solenoid valve assembly 10 has an inlet flow channel 11 and an outlet flow channel. The solenoid valve assembly 10 is used to control the on-off between the inlet flow channel 11 and the outlet flow channel.

[0035] The check valve assembly 20 is arranged in the outlet flow channel. The check valve assembly 20 is configured to allow fluid to flow unidirectionally from the inlet flow channel 11 to the outlet flow channel.

[0036] Optionally, the check valve assembly 20 is connected to the solenoid valve assembly 10. The check valve assembly 20 has a receiving cavity 21 and a second sub-flow channel communicating with the receiving cavity 21. The receiving cavity 21 communicates with the second sub-flow channel. Optionally, the connection between the check valve assembly 20 and the solenoid valve assembly 10 is indirect, and the two are arranged opposite to each other. Optionally, the connection between the check valve assembly 20 and the solenoid valve assembly 10 is direct. Optionally, please refer to Figure 1 and Figure 2, the solenoid valve assembly 10 and the check valve assembly 20 are of an integrated structure. Specifically, the above arrangement makes the regulating valve have a small occupied space, high integration, and a simple structure.

[0037] By arranging the check valve assembly 20 in the outlet flow channel of the solenoid valve assembly 10 in the regulating valve, at least the risk of external leakage of the check valve assembly is reduced, thereby reducing the risk of external leakage of the regulating valve. In addition, arranging the check valve assembly 20 in the outlet flow channel of the solenoid valve assembly 10 saves space layout and is conducive to cost reduction and weight reduction of the regulating valve.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 , the check valve assembly 20 divides the outlet flow channel into a first sub-flow channel 13 and a second sub-flow channel 22. When the check valve assembly 20 is in the open state, the first sub-flow channel 13 and the second sub-flow channel 22 are connected to enable the fluid to flow from the inlet flow channel 11 through the first sub-flow channel 13 to the second sub-flow channel 22; when the check valve assembly 20 is in the closed state, the first sub-flow channel 13 and the second sub-flow channel 22 are not connected.

[0039] Optionally, please refer to Figure 1 and Figure 2 , the solenoid valve assembly 10 includes a valve body 14. The valve body 14 extends into the first sub-flow channel 13 and is connected to the valve block 30. The valve body 14 encloses a receiving cavity 12 and an outlet flow channel. The valve body 14 is also provided with a through hole 141 to form an inlet flow channel 11. Optionally, the through hole 141 can be a polygonal hole, an oval hole, a circular hole, an irregular hole, etc. Optionally, the through hole 141 can specifically be but is not limited to a quadrilateral hole, a hexagonal hole, an octagonal hole, an oval hole, etc. Optionally, the number of the through holes 141 is multiple, and the multiple through holes 141 are arranged at intervals. Optionally, the multiple through holes 141 are arranged at equal intervals.

[0040] Optionally, the cross-sectional shape of the first sub-flow channel 13 can be a polygon, an oval, a circular shape, an irregular shape, etc. Optionally, the cross-sectional shape of the first sub-flow channel 13 can specifically be but is not limited to a quadrilateral, a hexagon, an octagon, an oval, etc. Optionally, the cross-sectional shape of the liquid inlet channel 32 can be a polygon, an oval, a circular shape, an irregular shape, etc. Optionally, the cross-sectional shape of the liquid inlet channel 32 can specifically be but is not limited to a quadrilateral, a hexagon, an octagon, an oval, etc.

[0041] Specifically, the one-way valve assembly 20 is disposed inside the valve block 30, which reduces the weight compared to the externally inserted and sealed one-way valve assembly 20 and also reduces the cost of components. Specifically, the one-way valve assembly 20 is disposed inside the valve block 30, eliminating the risk of external leakage of the sealed one-way valve assembly 20. The one-way valve assembly 20 can automatically control the connection and disconnection between the first sub-channel 13 and the second sub-channel 22 without the need to manually add an additional regulating valve structure for control, reducing the complexity of the regulating valve structure.

[0042] It can be understood that the one-way valve assembly 20 can be controlled to be in an open state or a closed state by fluid pressure, or by electromagnetic force, or by other means, and can be selected according to the actual application situation.

[0043] In one embodiment, please refer to Figure 1 and Figure 2 , the first sub-channel 13 is closer to the inlet channel 11 than the second sub-channel 22. When the fluid flows from the inlet channel 11 to the outlet channel, the pressure in the first sub-channel 13 is greater than the pressure in the second sub-channel 22, causing the one-way valve assembly 20 to be in an open state; when the fluid flows from the outlet channel to the inlet channel 11, the pressure in the second sub-channel 22 is greater than the pressure in the first sub-channel 13, causing the one-way valve assembly 20 to be in a closed state.

[0044] Optionally, the flow rate of the fluid flowing from the inlet channel 11 to the outlet channel is determined according to user requirements. Specifically, the opening and closing of the one-way valve assembly 20 can be automatically controlled according to the pressure situation, and the one-way valve assembly 20 can be selectively used without any adjustment to the structure of the valve block 30 itself, reducing the complexity of the regulating valve structure.

[0045] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 , the one-way valve assembly 20 includes a receiving cylinder 23 and a valve core assembly. The receiving cylinder 23 is fixed to the inner wall of the outlet channel to divide the outlet channel into a first sub-channel 13 and a second sub-channel 22. The receiving cylinder 23 has a valve port 31, and the valve core assembly can reciprocate to open or close the valve port 31, causing the one-way valve assembly 20 to be in an open state or a closed state.

[0046] Optionally, the shape of the cross-section of the receiving cylinder 23 along the axial direction can be polygonal, elliptical, circular, irregular, etc. Optionally, the shape of the cross-section of the receiving cylinder 23 along the axial direction can specifically be but is not limited to quadrilateral, hexagonal, octagonal, elliptical, etc.

[0047] Optionally, please refer to Figure 1 and Figure 2, the valve body 14 includes a first cylinder 142, a connecting portion 143, and a second cylinder 144. The first cylinder 142 sleeves the second cylinder 144 and is spaced apart in the radial direction. The first cylinder 142 encloses an accommodation cavity 12, and the second cylinder 144 encloses a partial outlet flow channel. The connecting portion 143 is connected to both the first cylinder 142 and the second cylinder 144; the first sub-flow channel 13 includes a first channel, a second channel, and a third channel that are sequentially connected. The first channel is communicated with the external space. The radial dimension of the third channel is smaller than that of the first channel, and the radial dimension of the first channel is smaller than that of the second channel.

[0048] Optionally, please refer to Figure 1 and Figure 2 , there is a gap between the outer peripheral surface of the first cylinder 142 and the inner wall surface of the second channel to form a liquid inlet cavity. The liquid inlet channel 32 and the inlet flow channel 11 are both communicated with the liquid inlet cavity. Optionally, the gap houses the fluid so that the fluid can flow to the accommodation cavity 12 at this place. Specifically, the gap perfects the fluid flow path.

[0049] Optionally, the first cylinder 142, the connecting portion 143, and the second cylinder 144 perfect the fluid flow path in the valve body 14.

[0050] Optionally, please refer to Figure 1 and Figure 2 , the solenoid valve assembly 10 further includes a regulating component 15. The regulating component 15 is housed in the accommodation cavity 12, and the regulating component 15 is adapted to move axially relative to the second cylinder 144.

[0051] Optionally, the solenoid valve assembly 10 further includes a regulating spring 16. The regulating spring 16 is connected to the regulating component 15. One end of the regulating spring 16 abuts against the inner wall surface of the accommodation cavity 12, and the other end abuts against the connecting portion 143. The solenoid valve assembly 10 further includes a coil. The working principle of the solenoid valve assembly 10 is that a magnetic field is generated after the coil is energized. The regulating component 15 moves under the action of the magnetic field. When the regulating component 15 moves downward, the outlet flow channel is closed. When the regulating component 15 moves upward, the outlet flow channel is opened under the action of the regulating spring 16, and the fluid flows out from the outlet flow channel.

[0052] Specifically, by providing that the check valve assembly 20 includes a housing cylinder 23 and a spool assembly, the housing cylinder 23 is fixed to the inner wall of the outlet flow channel to divide the outlet flow channel into a first sub-flow channel 13 and a second sub-flow channel 22. The housing cylinder 23 has a valve port 31. The spool assembly can reciprocate to open or close the valve port 31 so that the check valve assembly 20 is in an open state or a closed state. By controlling the movement of the spool assembly, the check valve assembly 20 is in an open state or a closed state. The structure is simple, thus reducing the complexity of the regulating valve structure.

[0053] In one embodiment, please refer to Figure 1 andFigure 2 In the direction from the second sub-channel 22 to the first sub-channel 13, the inner diameter of the valve port 31 gradually decreases.

[0054] It can be understood that the axial cross-section of the valve port 31 is circular, and the inner wall of the valve port 31 is generally a conical surface. In the direction from the second sub-channel 22 to the first sub-channel 13, the inner diameter of the valve port 31 gradually decreases. Thus, when the fluid flows from the outlet channel to the inlet channel, the pressure in the second sub-channel 22 is greater than the pressure in the first sub-channel 13. Under the action of the pressure difference, the valve core assembly moves in the direction from the second sub-channel 22 to the first sub-channel 13. And in the direction from the second sub-channel 22 to the first sub-channel 13, since the inner diameter of the valve port 31 gradually decreases, the valve core assembly can close the valve port 31 through movement, making the one-way valve assembly 20 in a closed state; conversely, when the fluid flows from the inlet channel to the outlet channel, the pressure in the first sub-channel 13 is greater than the pressure in the second sub-channel 22. Under the action of the pressure difference, the valve core assembly moves in the direction from the first sub-channel 13 to the second sub-channel 22. Since the inner diameter of the valve port 31 gradually increases in the direction from the first sub-channel 13 to the second sub-channel 22, the valve core assembly can open the valve port 31 through movement, making the one-way valve assembly 20 in an open state.

[0055] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the valve core assembly includes a valve core 25 that is selectively and sealingly engaged with the valve port 31, and the valve core 25 is at least partially in conical engagement with the valve port 31.

[0056] Optionally, one end of the valve core close to the valve port 31 is in conical engagement with the valve port 31, so as to guide the movement of the valve core 25.

[0057] In one embodiment, please refer to Figure 1 and Figure 2 , the regulating valve further includes a first sealing member, and a first sealing member is disposed between the outer wall of the valve core 25 and the inner wall of the valve port 31.

[0058] Optionally, the first sealing member is annular. Optionally, the first sealing member can be an elastically deformable structure for convenient installation.

[0059] By disposing a first sealing member between the outer wall of the valve core 25 and the inner wall of the valve port 31, a good sealing effect can be achieved. Optionally, a sealing groove is provided on the outer wall of the valve core 25 or the inner wall of the valve port 31, and the first sealing member is disposed in the sealing groove.

[0060] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the regulating valve further includes a limiting assembly, and the receiving cylinder 23 is fixed to the inner wall of the outlet channel through the limiting assembly.

[0061] Optionally, the limiting component can be an elastically deformable structure for convenient installation. By providing that the regulating valve further includes a limiting component, the receiving cylinder 23 is fixed to the inner wall of the outlet flow channel through the limiting component. The limiting component plays a role in fixing and limiting the receiving cylinder 23, preventing the receiving cylinder 23 from shifting, and improving the stability of the connection and fixation of the receiving cylinder 23.

[0062] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the limiting component includes a first limiting member and a second limiting member 33. The first limiting member and the second limiting member 33 are respectively located at both ends of the receiving cylinder 23 to limit the movement of the receiving cylinder 23 along the flow direction of the outlet flow channel.

[0063] Optionally, both the first limiting member and the second limiting member 33 can be adapted to the outer shape of the receiving cylinder 23. Optionally, at least one of the first limiting member and the second limiting member 33 is an elastically deformable structure for convenient installation. The first limiting member and the second limiting member limit the receiving cylinder 23 from both ends of the receiving cylinder 23, improving the stability of the limitation of the receiving cylinder 23.

[0064] By providing that the limiting component includes a first limiting member and a second limiting member 33, the first limiting member and the second limiting member 33 are respectively located at both ends of the receiving cylinder 23 to limit the movement of the receiving cylinder 23 along the flow direction of the outlet flow channel.

[0065] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the first limiting member is located at one end of the receiving cylinder 23 close to the first sub-channel 13. The first limiting member can be a clamping member, and the first limiting member is adapted to be clamped with the inner wall of the first sub-channel 13 and abuts against one end of the receiving cylinder 23 close to the first sub-channel 13; and / or, the second limiting member is located at one end of the receiving cylinder 23 close to the second sub-channel 22. The second limiting member is adapted to be fixed to the inner wall of the second sub-channel 22 and abuts against one end of the receiving cylinder 23 close to the second sub-channel 22.

[0066] It is understandable that both the first limiter and the second limiter can be clamping members, or both the first limiter and the second limiter can be fixed to the inner wall of the outlet flow channel, or one of the first limiter and the second limiter is fixed to the inner wall of the outlet flow channel, and the other is a clamping member clamped to the inner wall of the outlet flow channel, which can be set according to actual needs. In order to facilitate installation, one of the first limiter and the second limiter can be fixed to the inner wall of the outlet flow channel, and after the receiving cylinder 23 is installed, the receiving cylinder 23 is abutted against the limiter, and then the other is clamped to the inner wall of the outlet flow channel by clamping, and abutted against the receiving cylinder 23, so that the receiving cylinder 23 is conveniently installed on the inner wall of the outlet flow channel.

[0067] Optionally, a groove is provided on the inner wall of the first sub-channel 13, and the first stopper is engaged with the groove. By providing the groove on the inner wall of the first sub-channel 13, the first stopper can be fixed to the inner wall of the first sub-channel 13 more firmly.

[0068] Optionally, the second stopper 33 protrudes from the inner wall of the second sub-channel 22, and the second stopper 33 stops the end of the receiving cylinder 23 of the one-way valve assembly 20 close to the outlet channel. In one embodiment, the second stopper 33 is integrally formed with the inner wall of the second sub-channel 22, so that it is more convenient to install.

[0069] In some embodiments, the first limit member is located at one end of the containing cylinder 23 close to the first sub-channel 13, and the first limit member is a clamping member, which is suitable for clamping with the inner wall of the outlet channel and abutting with the end of the containing cylinder 23 close to the first sub-channel 13; the second limit member 33 is located at one end of the containing cylinder 23 close to the second sub-channel 22, and the second limit member 33 is suitable for being fixed to the inner wall of the outlet channel and abutting with the end of the containing cylinder 23 close to the second sub-channel 22.

[0070] It can be understood that when the receiving cylinder 23 is assembled from the first sub-channel 13 to the second sub-channel 22, the receiving cylinder 23 will be limited by the second limiting member 33, and then the first limiting member is clamped into the groove on the inner wall of the first sub-channel 13 and abutted against the end of the receiving cylinder 23 close to the first sub-channel 13, thereby limiting the receiving cylinder 23 in the outlet channel.

[0071] Optional, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The first limit member 26 is engaged with the inner wall of the first sub-channel 13 , the first limit member 26 abuts against one end of the receiving cylinder 23 close to the first sub-channel 13 , and the valve stem 24 is passed through the first limit member 26 .

[0072] Optionally, a groove is formed on the inner wall surface of the first sub-channel 13, and the first limiting member 26 is disposed in the groove. The first limiting member 26 has good elasticity and can automatically return to its original shape after deformation. Optionally, the first limiting member 26 is a ring with a notch. The outer diameter of the first limiting member 26 is larger than the outer diameter of the one-way valve assembly 20 and smaller than the inner diameter of the groove. During assembly, the first limiting member 26 is placed into the first sub-channel 13 in a deformed state and pushed downward by a tooling. After the first limiting member 26 reaches the groove, it automatically returns to its original shape and snaps into the groove. When removing the first limiting member 26, a special first limiting member 26 pliers is used to clamp the notch of the first limiting member 26, and the first limiting member 26 is deformed and then taken out.

[0073] Optionally, the fixing method of the one-way valve assembly 20 is not limited to being fixed by a limiting component, and it can also be fixed by means such as threads.

[0074] Specifically, the one-way valve assembly 20 is fixed inside the valve block 30 by the first limiting member 26, which is convenient for disassembly and assembly. There is no need to use equipment such as a tightening machine, and there is no need to worry about damaging the threads during disassembly and assembly.

[0075] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the regulating valve further includes a second seal 42, and the second seal 42 is disposed between the inner wall of the receiving cylinder 23 and the outlet channel.

[0076] Optionally, the second seal 42 can be an elastically deformable structure for convenient installation and can play a good sealing role. By providing the second seal 42, when the valve core assembly closes the valve port 31, leakage of the fluid between the first sub-channel 13 and the second sub-channel 22 can be avoided.

[0077] In one embodiment, the one-way valve assembly 20 further includes a spring 27, and the spring 27 abuts between the receiving cylinder 23 and the valve core assembly to provide a reset force for the valve core assembly.

[0078] Optionally, the number of springs can be multiple or one. Optionally, the number of springs is multiple, and multiple springs all abut between the receiving cylinder 23 and the valve core assembly. The number of springs is determined according to requirements to accurately provide a reset force for the valve core assembly.

[0079] By providing that the one-way valve assembly 20 further includes a spring 27, and the spring 27 abuts between the receiving cylinder 23 and the valve core assembly to provide a reset force for the valve core assembly, the one-way valve assembly 20 is in a normally closed state.

[0080] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3, the spool assembly includes a valve stem 24 and a spool 25 that are fixedly connected. The spool 25 is used for selectively sealing cooperation with the valve port 31. One end of the spring 27 abuts against the receiving cylinder 23, and the other end of the spring 27 abuts against the end of the valve stem 24 away from the spool 25.

[0081] Optionally, please refer to Figure 1 and Figure 2 , one end of the valve stem 24 is connected to the spool 25. The spool 25 abuts against the inner wall surface of the receiving cylinder 23.
