Diaphragm deluge valve "Diaphragm deluge valve is composed of valve body, valve clack, rubber diaphragm and so on. There are three cavities in the valve: inlet, outlet and top chamber. Normally, the top chamber and the inlet have pressure water, and the valve disc is in the closed position by the 2:1 differential pressure ratio. In the event of a fire, after any transmission device opens the electromagnetic pressure relief valve, the pressure in the top chamber drops rapidly, the valve flap opens, and water flows through the inlet to the outlet to fill the entire deluge pipe network.
Diaphragm deluge valve has only one movable part, so it is sensitive and rapid in action, can automatically reset after action and does not require frequent maintenance. It is an ideal deluge valve.
