The Working Principle of a Breathing Valve

The working principle of the breathing valve:

The breathing valve is equipped with a spring-limited valve plate, which determines whether to exhale or inhale based on positive or negative pressure. The breathing valve should have the functions of releasing both positive and negative pressure. Specifically: when the container is under positive pressure, the breathing valve opens to exhale gas and release the positive pressure; when the container is under negative pressure, the breathing valve opens to inhale gas and release the negative pressure. This ensures that the pressure remains within a certain range, guaranteeing the safety of the container.

Features of the Breathing Valve:

The valve body of the breathing valve can withstand a water pressure of 0.2MPa without any leakage or deformation. The breathing valve's resistance to low temperatures is maintained when the relative humidity of the air exceeds 70% and the temperature is -30℃. After 24 hours of freezing, the opening pressure of the valve disk meets the working pressure requirements (allowing a pressure difference of ±20Pa).
