[0006] From the above scheme, it can be seen that the quick-connection module is connected with the air inlet seat on the valve to realize quick connection of the valve, the limit ball extends out of the limit through groove and is limited in the limit ring groove to realize clamping of the air inlet seat and the quick-connection pipe seat, the limit ring groove is arranged in arc transition for matching with the limit ball, the limit sliding sleeve moves the sliding groove to make the limit ball fall into the sliding groove, thereby releasing the clamping between the air inlet seat and the quick-connection pipe seat.

[0007] The valve further includes a valve body, a valve core connected in the valve body, a valve stem assembly rotatably connected to the valve body, and an air outlet seat provided on the valve body. As can be seen, the valve stem assembly rotates to rotate the valve core to adjust and control the gas.

[0008] The quick-connect fitting includes an integrally formed quick-connect mounting part and a threaded connection part. The threaded connection part is provided with an external thread, and a connecting pipe is threadedly connected to the threaded connection part. The quick-connect fitting is connected to the connecting pipe.

[0009] The connecting pipe includes an integrally formed connecting part and an air inlet pipe part. The threaded connecting part is provided with an external thread, and the inner wall of the connecting part is provided with an internal thread that mates with the threaded connecting part.

[0010] The limiting sleeve has an annular anti-slip portion on its outer circumference. Therefore, the anti-slip portion is used to prevent slippage when the limiting sleeve is slidable.

[0011] The air intake seat has a limit stop on the outer side of the end face of the quick-connect mounting part. Therefore, the limit stop is used to prevent the limiting sleeve from sliding off the end of the quick-connect mounting seat. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figs. 1 to 4As shown, this utility model is an integrated quick-connect valve with an air inlet, including a valve 1, an air inlet seat 2, a quick-connect module, a limiting annular groove 21 on the outer side of the air inlet seat 2, the limiting annular groove 21 being arc-shaped, and the quick-connect module including a quick-connect pipe seat 3 communicating with the air inlet seat 2, a limiting sleeve 4 slidably disposed on the quick-connect pipe seat 3, and a valve positioned between the quick-connect pipe seat 3 and the limiting sleeve 4. The limiting ball assembly includes a limiting sleeve 4 sleeved on the quick-connect fitting 3. The limiting ball assembly comprises several limiting balls 5 arranged in a ring on the quick-connect fitting 3. A sliding groove 40 is provided on the inner side of the limiting sleeve 4. A limiting through groove 30 adapted to the limiting balls 5 is provided on the quick-connect fitting 3. The end of each limiting ball 5 extends out of the limiting through groove 30 and contacts the limiting ring groove 21 for quick-connect locking. An anti-slip portion 41 is arranged in a ring on the outer circumference of the limiting sleeve 4. In this embodiment, two sets of anti-slip portions 41 are arranged in parallel, with a gap between the two sets of anti-slip portions 41.

[0018] The valve 1 also includes a valve body 11, a valve core connected to the valve body 11, a valve stem assembly 12 rotatably connected to the valve body 11, and an air outlet seat 13 disposed on the valve body 11.

[0019] The quick-connect fitting 3 includes an integrally formed quick-connect mounting part 31 and a threaded connection part 32. The threaded connection part 32 is provided with external threads, and a connecting pipe 6 is threadedly connected to the threaded connection part 32. The quick-connect fitting 3 communicates with the connecting pipe 6. The air intake seat 2 is provided with a limit stop 33 on the outer side of the end face of the quick-connect mounting part 31. In this embodiment, the quick-connect fitting 3 is provided with a connecting through hole 34, and the diameter of the connecting through hole 34 is adapted to the outer diameter of the air intake seat 2.

[0020] The connecting pipe 6 includes an integrally formed connecting portion 61 and an air intake pipe portion 62. The threaded connecting portion 32 is provided with an external thread, and the inner wall of the connecting portion 61 is provided with an internal thread that engages with the threaded connecting portion 32. In this embodiment, a protrusion is provided on the outer circumferential surface of the connecting pipe 6 between the connecting portion 61 and the air intake pipe portion 62.

[0021] The working process of this utility model is as follows: When the locking connection is made, the anti-slip part 41 holds the limiting sleeve 4, causing the limiting sleeve 4 to slide backward on the quick-connect mounting part 31 on the quick-connect seat 3. The end of the limiting ball 5 falls from the limiting through groove 30 into the sliding groove 40. The quick-connect seat 3 is then fitted onto the air inlet seat 2 through the connecting through hole 34, causing the limiting sleeve 4 to slide forward. The limiting ball 5 falls into the limiting ring groove 21. The limiting sleeve 4 is then released, thereby achieving the locking between the quick-connect seat 3 and the air inlet seat 2 on the valve 1. When the locking is released, the limiting sleeve 4 is held by the anti-slip part 41 and then slid backward on the quick-connect seat 3, causing the limiting ball 5 to fall into the limiting through groove 30, thereby releasing the locking between the air inlet seat 2 and the quick-connect seat 3.

[0022] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
