& Product Overview:
The all-weather breathing valve, also called an all-weather fire damper, is installed on oil and liquid storage tanks to eliminate positive and negative pressure gases in the tank, making it easy for liquids in the tank to enter and exit. If the tank is not equipped with a breathing valve and there are certain obstacles in the inflow and outflow of liquid in the tank, the tank is likely to deform and vibrate. It has explosion-proof and fire-retardant properties.
Product principle:
The all-weather breathing valve is installed on the top of the storage tank to solve the positive pressure and negative pressure of the gas in the tank, so that the liquid in the tank is not hindered. When the external liquid is input into the tank, there is A large amount of gas is expelled outward (called positive pressure). For example, when the liquid in the tank is exported to the outside, the air inside the tank must be sucked into the tank from the outside (called negative pressure). If the breathing valve automatically closes when it stops working, the liquid and gas in the tank will not leak out, thus ensuring the quality of the liquid in the tank.
