FRPP breathing valve with exhalation connection and double connection PP interface hydrochloric acid storage tank

PP breathing valve is a product that maintains the pressure balance of the storage tank and reduces medium volatilization. The breathing valve fully utilizes the pressure bearing capacity of the storage tank itself to reduce medium emissions. Its principle is to use the weight of the positive and negative pressure valve discs to control the exhaust positive pressure and suction negative pressure of the storage tank; When the medium is pumped out of the tank, the pressure in the upper gas space inside the tank decreases, reaching the operating negative pressure of the breathing valve. The atmosphere outside the tank will open the negative pressure valve disc of the breathing valve, allowing external gas to enter the tank, causing the pressure inside the tank to continue to decrease, and balancing the air pressure inside and outside the tank to protect the device of the tank.
