All-Weather Pressure Vacuum Breather Valve


Breathing valve is a safe and energy saving product to maintain tank pressure balance and reduce medium volatilize. Breathing valve makes full use of the pressure bearing capacity of the tank itself to reduce medium emission. Its principle is to use the weight of the positive and negative pressure valve disc to control the exhaust positive pressure and suction negative pressure of the tank.When the medium is pumped out of the tank, so that the pressure of the upper gas space in the tank drops, to achieve the operation of the negative pressure of the breathing valve, the atmosphere outside the tank will top open the negative pressure valve disc of the breathing valve top open, so that the outside gas enters the tank, so that the pressure in the tank no longer continues to fall, so that the pressure balance between the tank and the tank, to protect the safety device of the storage tank.
