The working principle of explosion-proof breathing valve: The explosion-proof breathing valve uses the stem on the positive pressure valve disc and the negative pressure valve disc to limit the valve plate, and the breath or inspiration is determined by the positive and negative pressure. The explosion-proof breathing valve has two functions of releasing positive pressure and negative pressure, which are as follows: when the container is under positive pressure, the positive pressure valve disc of the breathing valve moves upward to open the exhaled gas to release positive pressure; When the container is under negative pressure, the negative pressure valve disc of the fire resistance breathing valve moves upward to open the suction gas and relieve the negative pressure. This ensures that the pressure is within a certain range and the safety of the container is ensured. The explosion-proof fire retardant breathing valve can not only maintain the pressure balance of the storage tank, ensure that the storage tank is destroyed during overpressure or vacuum, but also reduce the media and loss in the tank.
