The valve core component 30 comprises a valve core head 31, a valve rod 32 and an elastic piece 34, the valve core head 31 and the valve rod 32 are fixedly connected or in limited connection or in an integrated structure, the valve core seat 20 comprises a guide portion 201, and the valve rod 32 is in sliding fit with the guide portion 201 along the axial direction of the valve core seat.
In order to prevent the elastic element 34 from coming off, the valve rod 32 includes a rod portion 50 and a limiting portion 321, and the limiting portion 321 is located at one end of the rod portion 50 away from the valve core head 31 and is integrally formed on the rod portion 50. One end of the elastic element 34 abuts against the valve core seat 20, the other end of the elastic element 34 abuts against the limiting part 321, the elastic element 34 is sleeved outside the valve rod 32, and the elastic element 34 can enable the valve core head 31 and the valve rod 32 to be reset to a valve closing state.
Referring to fig. 3 and 4, the valve stem 32 has a cavity 63 and at least two deformation portions 51, the deformation portions 51 include at least a part of the limiting portion 321, the deformation portions 51 are located outside the cavity 63, two or more deformation portions 51 are arranged at intervals around the cavity 63, where the outside is referred to the axis of the stem 50, and in the present embodiment, there are 3 deformation portions 51. The deformation 51 comprises a first slot 52, the first slot 52 comprising at least two receiving slots 53, the deformation 51 having a second outer side wall 511 and an end wall 512, the receiving slots 53 being located between adjacent deformations 51, and the receiving slots 53 communicating with the cavity 63. In order to make the limiting part 321 be able to deform into the receiving groove 53 as much as possible, the receiving groove 53 is defined to have a groove depth H1 along the axial direction of the limiting part 321, the length of the limiting part 321 along the axial direction thereof is L1, and L1< H1. The receiving groove 53 includes a bottom wall 531 and a side wall 532, the stem 32 has a rounded portion 54, the rounded portion 54 is located between the bottom wall 531 and the side wall 532, and the rounded portion 54 smoothly connects the bottom wall 531 and the side wall 532 of the receiving groove 53.
Because the deformation direction of the deformation part 51 is different from the compression or stretching direction of the elastic element 34, the elastic element 34 is axially limited at the limiting part 321, and the deformation part 51 can be bent and deformed towards one side of the accommodating groove 53, so that at least part of the limiting part 321 is positioned in the accommodating groove 53, and the axial movement of the elastic element 34 is avoided.
Referring to fig. 3, 4 and 5, the stopper 321 has a guide wall 55, the guide wall 55 is located on the outer periphery of the stopper 321 on the side away from the axis thereof, and the guide wall 55 is inclined toward the side of the axis of the stopper 321 in the axial direction from the rod 50 to the stopper 321 in order to facilitate the installation of the elastic member 34. In addition, one end of the limiting portion 321 away from the rod portion 50 is defined as a first end 56, one end of the limiting portion 321 close to the rod portion 50 is defined as a second end 57, the elastic member 34 has an installation space 341 through which the valve rod 32 can axially penetrate, and the diameter of the first end 56 of the limiting portion 321 is smaller than the minimum diameter of the installation space 341.

When the elastic member 34 is installed, since the diameter of the first end 56 of the limiting portion 321 is smaller than the minimum diameter of the installation space 341 of the elastic member 34, friction exists between the elastic member 34 and the limiting portion 321, and the smoothly-transitioned transition portion 62 can reduce abrasion.
When the unidirectional member 2 is mounted, various mounting methods are possible.
Installation mode 1: one end of the valve stem 32 firstly passes through the guide portion 201 of the valve core seat 20, then the large diameter portion 58 of the elastic element 34 faces the valve stem 32, and when the valve stem 32 passes through the installation space 341 of the elastic element 34, because the limiting portion 321 and the elastic element 34 form interference, during the process of passing the elastic element 34, the deformation portion 51 is subjected to extrusion force and bends and deforms towards one side of the accommodating groove 53, so that the elastic element 34 is sleeved into the rod portion 50. When the elastic element 34 axially moves to the shoulder 60, the elastic element 34 no longer interferes with the limiting portion 321, so the deformation portion 51 rebounds to the state of axially limiting the elastic element 34, one end of the elastic element 34 abuts against the valve core seat 20, and the other end abuts against the shoulder 60, and at this time, the installation is completed, and no extra limiting device is needed to be installed to prevent the elastic element 34 from being disengaged.
Installation mode 2: the elastic element 34 is axially compressed in advance, one end of the elastic element is abutted to the guide portion 201, the valve rod 32 penetrates through the valve core seat 20 from the side far away from the elastic element 34 and simultaneously penetrates through the elastic element 34, when the limiting portion 321 penetrates through the elastic element 34, the axial size is larger than the inner space of the elastic element 34, the limiting portion 321 is subjected to extrusion force, the deformation portion 51 bends and deforms towards the side of the accommodating groove 53 until the limiting portion 321 completely penetrates through the elastic element 34, and the limiting portion 321 rebounds to the state of the axial limiting elastic element 34, so that the installation is completed. The mounting manner of the unidirectional member 2 includes, but is not limited to, these two.

The valve core seat 20 has a valve port portion, the valve port 33 is located at the valve port portion, and the inner wall of the valve port portion is flared along the valve opening direction. In order to improve the sealing performance, a first sealing ring is sleeved outside the valve core head 31, and the valve core head 31 is abutted against the wall of the valve port part through the first sealing ring so as to close the valve port 33.
Referring to fig. 1 and 7, the valve core seat 20 includes a main body portion 21 and elastic clamping members 22, the elastic clamping members 22 are located on one side of the main body portion 21 relatively close to the elastic members 34, at least two elastic clamping members 22 are provided, and each elastic clamping member 22 is arranged along the circumferential direction of the main body portion 21 in an array manner, in this embodiment, four elastic clamping members 22 are provided.

A first surface is defined, the first surface is perpendicular to the axial direction of the valve stem 32, and the projection of the second sub-portion 224 on the first surface is located outside the main body portion 21, where the outside is outside the outer boundary of the main body portion 21. The resilient latch 22 has a deformable ability, and the second sub-portion 224 can be deformed into the avoiding groove 211 when being pressed. Therefore, when the one-way component 2 is installed, the second sub-portion 224 is extruded into the avoiding groove 211 in advance, when the one-way component 2 is installed to a preset position in the valve body 10, the elastic clamping piece 22 can be popped out to the limiting groove 101 of the valve body 10 which is processed in advance, the axial limiting of the one-way component 2 is achieved, the limiting function of a split washer is replaced, and the installation process is relatively simple.
The resilient clip 22 includes a connecting end 225 and a cantilevered end 226. The avoiding groove 211 includes a fourth sidewall 2113, the connecting end 225 is connected to the fourth sidewall 2113 of the avoiding groove 211, the elastic clip 22 extends from the connecting end 225 to the cantilever end 226 along the circumferential direction of the main body 21, at least a portion of the cantilever end 226 is located in the second sub-portion 224, and the radial width of the connecting end 225 is greater than the radial width of the cantilever end 226. The elastic clip 22 includes a second side wall 221, and the second side wall 221 faces the side of the valve stem 32 and is at least partially located in the avoiding groove 211.

The stress of elasticity joint spare 22 mainly concentrates on connecting portion, and when elasticity joint spare 22 was extruded to dodging in the groove 211, the extrusion force that link 225 received relatively near valve rod 32 one side is the biggest, and the deflection of this part when thickening portion 23 sets up, can increase by the extrusion, and consequently elasticity is bigger, and the speed of recovering the shape is faster relatively, has improved the installation effectiveness relatively.
The resilient clip 22 further includes a third sidewall 222, the third sidewall 222 is opposite to the second sidewall 221 and away from the valve stem 32, and the third sidewall 222 is smoothly connected to the first outer sidewall 2114 of the body portion 21.

When the fluid pressure is lower than the preset value, that is, the axial pressure applied to the spool head 31 is smaller than the elastic force of the elastic member 34, the elastic member 34 rebounds and resets, and the valve port 33 is closed again by the spool head 31.
In the installation process of the one-way component 2, the second sub-portion 224 of the elastic clamping member 22 needs to be pressed inwards in advance until the valve core seat 20 can be installed in the valve body 10, when the one-way component 2 is pushed to a preset position, the second sub-portion 224 of the elastic member 34 pops outwards and is clamped in the valve body 10, when an axial force is applied to the one-way component 2, the wall of the second sub-portion 224 abuts against the valve body 10 to form a limit position, therefore, a split washer does not need to be installed, and the installation process is greatly simplified.
Example two:

The clamping portion 64 is located on one side, close to the limiting portion 321, of the rod portion 50, a second groove portion 65 is formed between the clamping portion 64 and the limiting portion 321 and used for limiting the elastic piece 34 in the circumferential direction or the axial direction, at least part of the elastic piece 34 is located in the second groove portion 65, the clamping portion 64 protrudes outwards relative to the rod portion 50, and the outer side is the side, away from the axis of the rod portion 50.
After the installation is finished, one end of the elastic piece 34 is clamped in the second groove part 65, and the elastic piece 34 forms axial and circumferential limiting, so that unnecessary friction generated in the using process is reduced.
Example three:
the difference between the third embodiment and the first embodiment is that: referring to fig. 9 and 10, the first sub-portion 223 is a rod, the second sub-portion 224 is a protrusion 40, the protrusion 40 protrudes relative to the fourth side wall 2113, and the protrusion 40 is fixedly connected or connected in a limited manner or is integrated with other portions of the elastic clamping member 22.

Here, two cases are included, that is, when the check member 2 is mounted, the valve rod 32 side enters the valve body 10 first or the valve core head 31 side enters the valve body 10 first, and the inclination directions of the guide surfaces 41 are different in the two cases.
The side of the convex part 40 far away from the elastic piece 34 is an abutting surface 42, and when an outward force is applied to the one-way component 2 after the one-way component 2 is installed, the abutting surface 42 of the convex part 40 acts on the valve body 10 to limit the axial displacement of the one-way component 2, wherein the outward force refers to a force opposite to the installation direction of the one-way component 2.
The one-way component 2 can be directly installed in the installation process, when the guide surface 41 of the convex portion 40 abuts against the valve body 10, the elastic clamping piece 22 has a component force which is bent and deformed in the avoiding groove 211, so that the elastic clamping piece 22 can be deformed to avoid the wall of the valve body 10, and when the one-way component 2 moves to the preset position, the second sub-portion 224 of the elastic piece 34 pops outwards and is clamped in the valve body 10 to form axial limiting.

In this embodiment, the valve body 10 further has a limiting groove 101, the limiting groove 101 is formed on the wall of the through hole 11, at least a part of the elastic clip 22 is located in the limiting groove 101, and the axial displacement of the valve core seat 20 is limited by abutting against the wall formed by the limiting groove 101. The limiting groove 101 may have various forms, in this embodiment, the limiting groove 101 is an annular groove disposed along the circumference of the valve core seat 20, and in order to reduce the shake of the one-way component 2 during use, the limiting groove 101 is in clearance fit between two walls of the valve core seat 20 in the axial direction and two side walls of the elastic clamping member 22. The one-way component 2 can be easily installed in the valve body 10 through the structure, after the clamping piece 22 is clamped into the limiting groove 101, the one-way component 2 is axially limited, other components do not need to be installed to fix the one-way component 2, the installation steps are simplified, and the assembly efficiency is improved.
When the check component 2 is in use, the fluid in the through hole 11 applies pressure to the valve core head 31, and when the fluid pressure reaches a preset value, that is, the axial pressure applied to the valve core head 31 is greater than the elastic force of the elastic element 34, the elastic element 34 is compressed under the action of the pressure, the valve rod 32 slides axially relative to the guide portion 201, and the valve port 33 is slowly opened to communicate with both sides of the valve core seat 20. When the fluid pressure is lower than the preset value, that is, the axial pressure applied to the spool head 31 is smaller than the elastic force of the elastic member 34, the elastic member 34 rebounds and resets, and the valve port 33 is closed again by the spool head 31.
The check valve with the check member 2 is elastically restored into the stopper groove 101 by the second sub-portion 224, so that the axial direction of the check member 2 is stopped, the function of a circlip is replaced, and the mounting process is simplified.
