Shanxi ventilation residual pressure valve _ _ Moritaka residual pressure valve ventilation air conditioning

Residual pressure valve used for clean air conditioning and there are special requirements of the occasion Shaanxi positive pressure ventilation residual pressure valve, usually installed in the wall need to maintain pressure on both the space well ventilated residual pressure valve Which, by adjusting the weights on the valve or pre-setting pressure, so as to achieve the set pressure when opening, full ventilation than the maximum differential pressure valve quoted exclude equilibrium after a certain amount of air pressure decreases to a minimum pressure is off. Residual pressure valve mounting position: "The people's air defense fire protection engineering design 09" is currently before the room or shared room when no direct air supply, air supply stairwell of not less than 25000m3 / h, and should be among the stairwell and before the room or shared room wall set residual pressure valve.
