ZSFZ wet alarm valve device and other components (such as pressure switches, water flow indicators, nozzles, etc.) constitute the ZS wet automatic sprinkler system, which is a widely used fixed fire extinguishing system. The system pipeline is filled with pressurized water and is in standby mode for long periods of time. It is suitable for use in environments with temperatures ranging from 4℃ to 70℃ (and can only be installed vertically), when a fire occurs in a protected area, the ambient temperature rises, and the temperature-sensitive element (glass ball) in the nozzle bursts, and the nozzle sprays water to the area where the fire occurred, and emits an alarm signal to achieve the purpose of alarm, fire suppression, and fire control.
This device is mainly composed of alarm valves, hydraulic alarm bells, delay timers, pressure switches, pressure gauges, drain valves, test ball valves, etc.
