Breathing the working principle of pneumatic valve

breathing pneumatic valve is to maintain tank pressure balance, reduce medium volatile energy saving products, the safety of the breathing pneumatic valve make full use of bearing capacity to reduce emissions of medium tank itself.


respiratory pneumatic valve structure ( Figure

breathing the principle of the pneumatic valve is the weight of the negative pressure pneumatic valve plate is used to control exhaust breathe in positive pressure and negative pressure storage tank. When the pressure of tank medium in respiratory control range of operating pressure in the pneumatic valve, breathing pneumatic valve does not work, keep the tank closure; When added to the tank medium, make the tank top gas pressure of the space, to achieve positive pressure breathing pneumatic valve operation, pressure pneumatic valve is open, the gas escape from exports pneumatic valve breathe, make the tank pressure not to increased; Beyond can take out medium, make the tank top gas pressure drop of the space, to breathe the pneumatic valve operating pressure, open the atmosphere outside the tank will be breathing pneumatic valve open negative pressure pneumatic valve plate, the gas into the tank, the tank pressure is no longer continue to fall, let the tank and tank pressure balance, to protect the safety of the tank.
