ZSFZ wet automatic sprinkler fire extinguishing system is a widely used fixed fire extinguishing system, composed of ZSFZ wet alarm valve device and other components (such as pressure switch, water flow indicator, sprinkler, etc.). The system is full of pressure water in the pipeline network and is in standby working state for a long time. It is suitable for use at ambient temperature of 4 ~70 C (and can only be installed vertically). When a fire occurs somewhere in the protected area, the ambient temperature rises, the temperature sensitive element (glass ball) of the sprinkler head breaks down, and the sprinkler automatic start system sprays water directly into the fire area, and gives an alarm signal,in order to achieve the purpose of alarm, fire extinguishing and fire control.
The device is mainly composed of alarm valve, hydraulic alarm bell, delay device, pressure switch, pressure gauge, drainage valve, test ball valve, etc.
