Description

Exhaust valve

Technical Field

The utility model relates to the technical field of exhaust valves, in particular to an exhaust valve.

Background

The exhaust valve is generally composed of a valve body, a floater arranged in the valve body and the like, gas enters the valve body from a cavity opening at the lower part of the valve body, and floats upwards to realize exhaust, and after the exhaust is finished, the floater falls back under the action of gravity to block the cavity opening at the lower part of the valve body again. When the exhaust valve in the prior art is used for exhausting, water can be sometimes introduced into the exhaust valve, when the water pressure is too high due to excessive water entering the exhaust valve, the water can squeeze the floater to enable the floater to float up and down, and then part of water can leak through the upper cavity opening of the valve body, so that the exhaust valve is invalid, the existing exhaust valve can only be used for exhausting, and the function is single.
