[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] In related technologies, a receiving groove is usually required to be made on the valve core in the valve body assembly for installing the sealing part. In order to restrict the axial movement of the sealing part, the size of the receiving groove is basically the same as the size of the sealing part. Once the sealing part is installed in the receiving groove, it is difficult to remove it, which increases the difficulty of disassembling and maintaining the valve body assembly and reduces the efficiency of disassembling and maintaining the valve body assembly.

[0032] The following is for reference. Figures 1-5 This invention describes a valve body assembly according to an embodiment of the present invention.

[0033] The valve body assembly 100 according to this utility model includes: a valve body 11, a valve seat assembly, a valve core 12, and a sealing part 13. A receiving cavity is formed in the valve body 11, and a first limiting part 111 is formed on the valve body 11. The valve seat assembly is received in the receiving cavity and a second limiting part 24 is provided on the valve seat assembly. The valve core 12 is disposed on the valve seat assembly and received in the receiving cavity. A sealing part is sleeved on the outer periphery of the valve core 12. The sealing part 13 is located between the first limiting part 111 and the second limiting part 24. The sealing part 13 abuts against the first limiting part 111 and the second limiting part 24 respectively to restrict the movement of the sealing part 13 along the axial direction of the valve core 12.

[0034] In some specific embodiments, the valve body assembly 100 comprises a valve body body 11, a valve seat assembly, a valve core 12, and a sealing portion 13. The valve body body 11 has an internal cavity for accommodating other components. A first limiting portion 111 is also formed on the valve body body 11. The cavity accommodates the valve seat assembly, the valve core 12, and the sealing portion 13. A second limiting portion 24 is provided on the valve seat assembly. The valve core 12 is disposed on the valve seat assembly. The sealing portion 13 is sleeved on at least a portion of the outer periphery of the valve core 12 and is located between the first limiting portion 111 and the second limiting portion 24. When the sealing portion 13 undergoes axial movement, it abuts against the first limiting portion 111 and the second limiting portion 24 respectively to restrict the sealing... The axial movement of the sealing part 13 ensures the stability and reliability of the sealing part 13 on the valve core 12, and improves the sealing effect and stability of the valve body assembly 100. Compared with the prior art method of opening a receiving groove on the valve core 12 to accommodate the sealing part 13 and restrict its movement, the method of assembling and disassembling the sealing part 13 in this application by using the first limiting part 111 and the second limiting part 24 to jointly restrict the axial movement of the sealing part 13, the method of assembling and disassembling the sealing part 13 in this application is simpler and more convenient. When the sealing part 13 is inspected, maintained and replaced, the sealing part 13 can be more easily removed from the valve body assembly 100, which improves the maintenance efficiency of the sealing part 13 and extends the service life of the valve body assembly 100.

[0035] According to this utility model, the valve body assembly 100 forms a first limiting part 111 on the valve body body 11 and a second limiting part 24 is provided on the valve seat assembly. The sealing part 13 is disposed between the first limiting part 111 and the second limiting part 24, and the sealing part 13 abuts against the first limiting part 111 and the second limiting part 24 respectively, so as to restrict the movement of the sealing part 13 along the axial direction of the valve core 12. This improves the stability and reliability of the overall structure of the valve seat assembly while reducing the difficulty of assembling and disassembling the valve seat assembly.

[0036] According to some embodiments of the present invention, the second limiting part 24 is sleeved on the valve core 12. One end face of the second limiting part 24 in the axial direction abuts against the end face of the sealing part 13 in the axial direction. When the sealing part 13 moves in the axial direction, one end of the sealing part 13 is blocked by the second limiting part 24, and the other end of the sealing part 13 is blocked by the valve body 11, thereby restricting the movement of the sealing part 13 in the axial direction and ensuring that the sealing part 13 will not move in the axial direction, thereby ensuring the sealing effect and stability of the valve body assembly 100.

[0037] According to some embodiments of the present invention, the second limiting portion 24 has a recessed groove 241 at one end in the axial direction. At least a portion of the sealing portion 13 is received within the groove 241, which ensures a tighter contact between the sealing portion 13 and the second limiting portion 24, improving sealing performance. The groove 241 provides a clear position for the sealing portion 13, helping to maintain the correct position of the sealing portion 13 and preventing displacement during operation. This not only improves the reliability of the seal but also simplifies the assembly process, making it easier to install the sealing portion 13 into place. Embedding a portion of the sealing portion 13 into the groove 241 makes the overall structure of the valve body assembly 100 more compact, reducing the volume of the valve body assembly 100 and improving the integration of the valve body assembly 100.

[0038] According to some embodiments of the present invention, at least a portion of the outer peripheral wall of the second limiting part 24 is spaced apart from the inner wall of the receiving cavity to form an airflow gap 206, allowing gas to flow within a specified space inside the receiving cavity, thereby improving the response speed and control accuracy of the valve. A mating hole 204 is formed on the second limiting part 24, which provides an installation position for the valve core 12. At least a portion of the valve core 12 is housed within the mating hole 204, and a first airflow channel is formed within the mating hole 204. The pressure and flow rate of the gas can be controlled by adjusting the position of the valve core 12. An air hole 205 is formed on the outer peripheral wall of the second limiting part 24 to connect the airflow gap 206 with the first airflow channel, allowing gas to enter the valve seat assembly from the outside of the valve seat assembly, thereby realizing the control of the internal pressure and flow rate of the valve body assembly 100.

[0039] According to some embodiments of this utility model, the vents 205 are configured as a plurality of vents arranged sequentially at intervals in the circumferential direction. By uniformly arranging a plurality of vents 205 in the circumferential direction, it can be ensured that the gas can be more evenly distributed when entering the first airflow channel from the airflow gap 206, avoiding the situation of excessively high or low local pressure in the first channel, thereby improving the stability of the valve body assembly 100. The plurality of vents 205 can increase the number of paths for gas to flow into the first airflow channel, which helps to reduce the resistance during gas flow and improve the flow efficiency of the valve body assembly 100. Since the vents 205 are evenly distributed in the circumferential direction, the gas can quickly and evenly fill the first airflow channel in a short time, accelerating the response speed of the valve body assembly 100 to pressure changes and ensuring its efficient operation under different working conditions.

[0040] According to some embodiments of the present invention, the valve seat assembly includes: a valve seat body 21 and an end cap 22. The valve seat body 21 is received in a receiving cavity and disposed at the other end of the second limiting portion 24 in the axial direction. The end cap 22 is received in the receiving cavity. A first groove is formed on one end of the end cap 22 in the axial direction, which is recessed inward. A third limiting portion is formed on the other end of the end cap 22 in the axial direction. The valve seat body 21 is received in the first groove. The valve seat body 21 abuts against the end face of the second limiting portion 24 and the inner wall of the first groove to restrict the movement of the valve seat body 21.

[0041] In some specific embodiments, a valve seat body 21 and an end cap 22 are provided within the valve seat assembly. The valve seat body 21 and the end cap 22 are respectively housed within a receiving cavity. The second limiting part 24 has a mating groove recessed inward at one end axially away from the sealing part 13. At least a portion of the valve seat body 21 is housed within the mating groove. The end cap 22 has a first groove recessed inward at one end axially. At least another portion of the valve seat body 21 is housed within the first groove. When the valve seat body 21 moves axially, both ends of the valve seat body 21 abut against the bottom wall of the mating groove and the bottom wall of the first groove, respectively, thereby restricting the axial movement of the valve seat body 21 and improving the stability and reliability of the valve seat body 21 within the receiving cavity. When the valve seat body 21 moves radially, the outer peripheral wall of the valve seat body 21 abuts against the inner peripheral wall of the first groove, thereby restricting the radial movement of the valve seat body 21 and further improving the stability and reliability of the valve seat body 21 within the receiving cavity.

[0042] According to some embodiments of the present invention, the valve seat assembly further includes an end cap nut 23, which is detachably connected to the valve body 11, allowing the end cap nut 23 to be easily removed from the valve body 11. This facilitates the installation or removal and maintenance of the end cap 22, simplifying the maintenance and replacement process. The end cap nut 23 is housed within a receiving cavity, and a fourth limiting portion is formed on the end cap nut 23. The fourth fitting portion engages with a third fitting portion formed on the end cap 22 to restrict the radial and axial movement of the end cap 22, improving the stability and reliability of the entire valve seat assembly. According to some embodiments of the present invention, one of the third and fourth limiting portions is a snap-fit ​​protrusion 31, and the other is a second groove 32. The snap-fit ​​protrusion 31 engages with the second groove 32 to restrict the radial movement of the end cap 22.

[0043] In some specific embodiments, the third limiting part can be configured as a snap-fit ​​protrusion 31, and the fourth limiting part can be configured as a second groove 32. The snap-fit ​​protrusion 31 extends into the second groove 32, and the end face of the snap-fit ​​protrusion 31 cooperates with the second groove 32. The outer peripheral wall of the snap-fit ​​protrusion 31 abuts against the inner peripheral wall of the second groove 32 to restrict the radial movement of the end cover 22. The end face of the snap-fit ​​protrusion 31 cooperates with the bottom wall of the second groove 32 to restrict the axial movement of the end cover 22. This can effectively prevent the end cover 22 from shifting or falling off during the operation of the valve body assembly 100, thereby ensuring the stability and reliability of the end cover 22 and improving the reliability of the valve seat assembly.

[0044] In addition, since the snap-fit ​​protrusion 31 and the second groove 32 have relatively simple and intuitive structures, fewer parts, fewer assembly steps, and simple and easy assembly methods, the assembly efficiency of the valve seat assembly is improved, while the difficulty of disassembling and maintaining the valve seat assembly is also reduced.

[0045] According to some embodiments of the present invention, an annular snap-fit ​​groove is formed on the outer peripheral wall of the end cover 22, and a sealing element 25 is also provided in the valve seat assembly. The sealing element 25 is sleeved on the outer periphery of the end cover 22 and received in the snap-fit ​​groove. Fixing the sealing element 25 in the annular snap-fit ​​groove can maintain the stability of the position of the sealing element 25 and avoid the sealing effect being affected by the displacement of the sealing element 25 due to external factors. When the end cover 22 contacts the inner wall of the receiving cavity, the sealing element 25 can be deformed by force to fill the tiny gap between the end cover 22 and the inner wall of the receiving cavity, effectively preventing gas from leaking out from these parts, thereby ensuring the overall sealing performance of the valve body assembly 100.
