General Information

ZSFM deluge alarm valve is comprised of the body, cover, diaphragm and other parts and fittings,  shunt valve, electromagnetic valve, pressure switches and water powered alarm. Deluge alarm valve can automatically make water flow in a single direction into the sprinkler system and send out alarm by means of wet, dry and electric control. It is extensively applied in deluge system, pre-action system, water mist system and water curtain system.

Working Principle

When the diaphragm is closed, the valve body is divided into upper and lower part. The upper part is connected with pipe network of automatic sprinkler system and the lower part is connected with pipe network of water supply system. The sealed cover and diaphragm form a cavity with pressure control. There is pipe connecting water supply pipe of upper valve body. When the cavity pressure and water supply line pressure keep balance, the diaphragm is in a sealing state(for the preparation condition). At this point, the water supply system is unable to supply water to the pipe network. When the cavity pressure drops, the diaphragm will automatically opens and supply water.
