ZSFG series fire fighting sprinkler valve quick response fire extinguishing deluge valve
The deluge valve is the ancillary facility of sprinkler system. It often cooperates with automatic fire alarm system to achieve remote control. Deluge valve allows water to flow into sprinkler unidirectionally and alarm at the same time.
The valve body is divided into three chambers: upper chamber, lower chamber and control chamber.
When a fire happens, fire alarm system probes it and starts solenoid valve to make pressurized water in control chamber flows out. Thus pressure in control chamber drops, valve flap open and water flow to sprinkler system pipe and was transported to sprinklers when force on valve flap assembly applied by rocker is smaller than force applied by water supply. Besides, water motor alarm will start to alarm. Pressure switch motions and send electrical signals to control system.
It is widely used in wet deluge system, dry deluge system, pre-acting system, water mist and
drencher system. Also applied with foam extinguishing system to constitute the foam spray system
and applied in explosive and flammable fire disasters.
