It is respectively equipped with the second air valve, second air valve includes the second valve body, tabletting, spring, fixing piece and filter core, second valve
Body and valve seat weld, filter core built in second valve body, and the second body top is equipped with tabletting, and the tabletting bottom surface is equipped with convex
Block, and tabletting top is connect with spring one end, the spring other end is connect with fixing piece, and the fixing piece and valve deck screw thread connect
It connects, is provided with exhaust outlet at left and right sides of second air valve.
Further, the quality of the gravity steel ball is 240-280 grams, and gravity steel ball inner hollow.
Further, the filter core is made of 3-5 layers of filter screen.
Compared with prior art, inlet valve of the invention, rationally, structure is simple for design, this inlet valve is equipped with two second gas
Valve and first air valve, the pressure in pipeline is adjusted by multiple air valves jointly, and adjustment speed is fast, high-efficient, has been avoided
Harmful or peculiar smell gas enters the room, reliable using feeling more relieved.
