[0016] Compared with the prior art, this utility model provides a novel pneumatic shut-off valve, which has the following beneficial effects:

[0017] 1. This novel pneumatic shut-off valve, through a connecting mechanism, uses a spring to drive a fixing plate, which in turn drives a block to insert into a square groove. The insertion rod is inserted into a socket groove, a rotating plate is inserted into a rectangular groove, a limiting plate is inserted into a limiting groove, and a telescopic plate is stretched and inserted into a square groove. This limits and fixes the position of the connecting rod, while simultaneously securing the block within the square groove. This allows the pipes to be fixed in position when connected to either the outlet or inlet pipe, preventing loosening and facilitating rapid control of gas delivery, thus reducing pressure loss and delay during gas transmission.

[0018] 2. This new type of pneumatic shut-off valve, through a stabilizing mechanism, allows the outlet and inlet pipes to be inserted into the surfaces of the pipes whose gas flow needs to be controlled. At the same time, a long plate is inserted into a long slot. Pushing the moving plate moves the inclined plate, which in turn moves the insert block into the slot. The insert block and the long plate are then threaded together with bolts. This allows the two pipes to be initially fixed in position when inserted into the outlet or inlet pipe, while also ensuring the stability of the pipes during insertion. Attached Figure Description

[0040] Furthermore, the long plate 42 is inserted into the long slot 49, and the moving plate 44 is pushed to drive the inclined plate 45. The inclined plate 45 drives the insert block 43 to be inserted into the slot 48. The insert block 43 and the long plate 42 are threadedly fixed by the bolt 46. When the two pipes 1 are respectively inserted into the water outlet pipe 2 or the water inlet pipe 3, the position of the pipes 1 can be initially fixed, and the pipes 1 can also remain stable when inserted.

[0041] In actual operation, when this device is used, the outlet pipe 2 and the inlet pipe 3 are respectively inserted into the surface of the pipe 1 that needs to control the gas flow. At the same time, the long plate 42 can be inserted into the long groove 49. Pushing the moving plate 44 causes the T-shaped block 401 to slide in the T-shaped groove 402. At the same time, the moving plate 44 drives the inclined plate 45, and the inclined plate 45 drives the insert block 43 to be inserted into the slot 48.

When the two pipes 1 are respectively inserted into the outlet pipe 2 or the inlet pipe 3, the position of the pipes 1 can be initially fixed, and the pipes 1 can also be kept stable during insertion.

[0042] Under the rebound force of spring 616, spring 616 drives fixed plate 615, fixed plate 615 drives block 613 to be inserted into square groove 614, square seat 6201 drives insertion rod 629 to be inserted into insertion slot 628, rotating plate 622 rotates on the surface of fixed rod 626 and is inserted into rectangular groove 621, limiting plate 624 is inserted into limiting groove 625, and telescopic plate 627 is stretched and inserted into square groove 623. The position of connecting rod 617 can be limited and fixed, and block 613 can also be fixed and inserted into square groove 614. This allows pipe 1 to be fixed in position when the two pipes 1 are respectively inserted into water outlet pipe 2 or water inlet pipe 3, preventing pipe 1 from loosening, so as to quickly control the gas delivery and reduce pressure loss and delay in the gas transmission process.
