Description
Technical field
The utility model belongs to technical field of valve manufacturing, is related to a kind of exhaust valve.
Background technique
The working principle of traditional exhaust valve is: when in system by gas overflowing, gas can climb along pipeline, most
It is gathered in the highest point of system eventually, and exhaust valve is generally all mounted on system highest point, when gas enters the aggregation of exhaust valve valve chamber
On the top of exhaust valve, as gas increases in valve, pressure rises, when gas pressure is greater than system pressure, gas can make
Intracavitary water surface decline, floating drum decline with water level；Open exhaust outlet；After gas drains, water level rises, and floating drum is also on
It rises, closes exhaust outlet.Existing exhaust valve does not have too much influence in most cases, but higher in some temperature
In use, there can be operator's careless manipulation on pump valve, lead to the gas being discharged by venthole or the water droplet with gas spillage
The case where scald.
In view of the above problems, people devise various exhaust valves, some have also applied for patent, such as in
State's Patent document data discloses a kind of exhaust valve [application number: 201420644487.2；Authorization Notice No.:
