Two-way breathing valve function:
Breathing valve (two-way breathing valve) is to maintain pressure balance tank, reducing medium volatile energy security products, take advantage of the breathing valve bearing capacity of the tank itself to reduce emissions from the media, the principle is to use the weight of positive and negative pressure to the valve disc control tank exhaust positive and negative pressure suction. When the pressure medium tank operating pressure range within the control of breathing valve, breathing valve does not work, keep the tank tightness; when the tank to replenish the medium, the pressure tank to the upper part of the gas space increases, reaching a two-way positive pressure breathing valve operation, the pressure valve is the top open, gas exports from breathing exhalation valve escape, so the tank pressure does not continue to increase; when the outside of the tank to pull out the media, so that the upper part of the gas space of the tank pressure drops, to breathe when operating vacuum valve outside of the tank atmosphere will open the top of the negative pressure breathing valve disc to open the top, so that outside air into the tank, the pressure inside the tank is no longer continue to decline, so the air pressure inside the tank and the tank outside the balance to protect the safety device of the tank.
