Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, in an embodiment of the present invention, an improved air pressure release valve includes a first cylinder 1, a sealing gasket 2, a movable block 3, a first fixture block 4, a spring 5, a cap 6, a second cylinder 7, an exhaust hole 8, an exhaust pipe 9, a sealing ring 10, a dust-proof net 11, a second fixture block 12, an air inlet 13, a protrusion 14, and a sponge block 15, wherein the exhaust hole 8 is formed in the first cylinder 1, the exhaust pipe 9 is disposed outside the exhaust hole 8, the exhaust pipe 9 is fixedly connected to a surface of the first cylinder 1, the second cylinder 7 is sleeved outside the exhaust pipe 9, the second cylinder 7 is in threaded connection with the exhaust pipe 9, the sponge block 15 is disposed inside the second cylinder 7, the dust-proof net 11 is disposed on one side of the sponge block 15, the dust-proof net 11 is fixedly connected to an inner wall of the second cylinder 7, the first cylinder 1 is provided with the air inlet 13, the protrusion 14 is fixedly, be provided with movable block 3 in the first barrel 1, the inner chamber sliding connection of movable block 3 and first barrel 1, the bottom fixedly connected with seal gasket 2 of movable block 3, the first fixture block 4 of top surface fixedly connected with of movable block 3, the one end that first fixture block 4 overcoat was equipped with spring 5, the other end endotheca of spring 5 is equipped with second fixture block 12, second fixture block 12 fixedly connected with block 6, block 6 and the inner wall threaded connection of first barrel 1, first barrel 1 overcoat has sealing washer 10.
