[0023] refer to Figures 1 to 3 According to a preferred embodiment of the present utility model, the novel inlet valve sleeve has the following structure: Figure 1As shown, it includes a valve sleeve body 10, which has a connecting end 11 and an insertion end 12. The insertion end 12 is connected to the connecting end 11, that is, the insertion end 12 and the connecting end 11 are integrally formed. Those skilled in the art should understand that the valve sleeve is disposed within an external valve housing. Specifically, the surface of the connecting end 11 is threaded, and the connecting end 11 is fixed to the external valve housing by a threaded connection. Furthermore, the end of the connecting end 11 opposite to the insertion end 12 also has a connecting hole, which is configured to cooperate with an external tool to fix it within the external valve housing by rotation.
[0024] It is worth mentioning that, such as Figure 1 As shown, the valve sleeve body 10 has a cross-sectional structure. The insertion end 12, away from the connecting end 11, also has a first connecting hole 101. The first connecting hole 101 is a stepped hole, having a large hole and a small hole, with the large hole communicating with the small hole. Notably, the insertion end 12 has a first extension 121, a second extension 122, and a third extension 123. The two ends of the second extension 122 are respectively connected to the first extension 121 and the third extension 123. Specifically, the large hole is located at the center of the end of the third extension 123.
[0025] Furthermore, the periphery of the third extension 123 also has a plurality of evenly distributed second connecting holes 102, which are arranged in a ring array, preferably four in number.
[0026] Furthermore, the surface of the second extension 122 is a beveled structure, and the surface of the second extension 122 also has a third connecting hole 103, one end of the third connecting hole 103 is connected to the outside, and the other end is connected to the small hole of the first connecting hole 101.
[0027] Specifically, the surface of the first extension 121 also has two first annular mounting grooves 12101, which are arranged opposite to each other and spaced apart by a predetermined distance. It is worth noting that the width of each first annular mounting groove 12101 is 2.2 mm, and the depth of each first annular mounting groove 12101 is 1.5 mm. It is also worth noting that the distance between the two first annular mounting grooves 12101 is 5.5 mm.
[0028] It should also be noted that between the two first annular mounting grooves 12101, there are also a plurality of first pressing grooves 12102 and a plurality of second pressing grooves 12103.

That is, by pressing the wall surface of the first extension 121, the four evenly distributed first pressing grooves 12102 or second pressing grooves 12103 are positioned such that the first pressing groove 12102 is close to one of the first annular mounting grooves 12101, and the second pressing groove 12103 is close to one of the first annular mounting grooves 12101. 2103 is close to another first annular mounting groove 12101. That is, when the first pressing groove 12102 and the second pressing groove 12103 are pressed together, the top wall surface of the two first annular mounting grooves 12101 on the side close to each other is deformed. That is, at this time, the opening of the two first annular mounting grooves 12101 is reduced to squeeze the sealing ring 100 placed in the first annular mounting groove 12101, so as to limit the position of the sealing ring 100 and prevent the sealing ring 100 from detaching from the corresponding first annular mounting groove 12101.
[0030] The structure of the deformed first annular mounting groove 12101 is as follows: Figure 3 As shown, the wall surface forming the first annular mounting groove 12101 also has a plurality of evenly distributed protrusions 121011, which will press against the surface of the sealing ring 100 to define the position of the sealing ring 100.
