Breathing valve principle is to use the pressure valve Marine valve tray to contain the weight of the tank vent breathe in positive pressure and negative pressure. 。 When the tank of the medium pressure in the respiration valve stem operation scope, the respiration valve closed, keep tightly closed tank; When the tank supplies medium, make the tank top gas pressure of the space, to achieve positive pressure breathing valve operation, pressure valve is open, the gas escape from the outlet of Industrial Valves breathe, make the tank pressure is then increased; When to can draw out medium, make the tank top gas pressure loss of the space, achieve the respiration valve operating pressure, open the atmosphere outside the tank will be breathing valve open the suction valve plate, the gas into the tank, the tank pressure decreased then, no longer let the tank and tank outside atmospheric pressure equilibrium, to try to take care of storage tank safety device. Q: breathing valve office the original to understand a: respiration valve is to protect the atmospheric storage tank pressure equalization, detract from the medium volatile security energy-saving products, the respiration valve make full use of the tank itself confined experienced emissions to detract from the media.
