Working Principle Of Breather Valve
Nov 23, 2017

The breathing valve is a spring limiting valve plate, which is determined by positive and negative pressure, or is called or sucked. There are gravity breathing valves, which are regulated by gravity. When the pressure in the container exceeds the pressure, the valve opens and releases pressure.

Specific description: when the pressure in the storage tank and the atmospheric pressure balance, the exhalation valve and the exhalation valve seat close coordination, suction valve and suction valve seat close coordination. When the pressure in the tank exceeds atmospheric pressure (i.e. had high pressure), the tank pressure directly on the bottom of breathing valve, the valve flap and to overcome the gravity and the role of the valve on the gas pressure, thereby opening the respiratory valve by A channel high pressure discharge tank, the tank pressure and atmospheric pressure keep the balance. When the tank pressure below the atmospheric pressure value (i.e. low negative pressure), the atmospheric pressure through the suction channel into B and directly on the bottom suction valve, and the valve to overcome the effects of gravity and on the top of the valve of the pressure inside the tank, thereby opening the intake valve complement to the pressure inside the tank, the tank the pressure and atmospheric pressure balance. When fire occurs, the fire may spread to the storage tank through the inlet, when the flame passes narrow pore breathing valve of the flame resistant core layer, due to the wall effect, the corrugating plate absorbs a great deal of heat, so that heat loss suddenly increased, so that the flame is extinguished.
