Dulge Alarm Valve

The dulge alarm valve is a fire extinguishing system consisting of a alarm valve, a detection control system, a sprinkler head, and necessary control valves, pipe fittings, pipes and pressure gauges. The ambient temperature of the rain alarm valve installation should not be less than 4°C.

When the solenoid valve and the manual control valve on the control line are closed, the hydraulic pressure in the diaphragm chamber (control chamber) of the deluge valve is maintained by the pressure compensator, so that the deluge valve can maintain the servo state. When the solenoid valve is commanded to open or the manual control valve is opened, the diaphragm chamber (control chamber) opens the deluge valve by means of pressure relief, and the water flow enters the system side to perform a water spray or a dry system to a wet system. . Widely used in rain system, preaction system, water curtain system, water fog system and foam system
