【簡單介紹】
【詳細(xì)說明】
ZSFZ type wet alarm valve system is a universal fixed fire extinguishing system, it consists of wet alarm valve, delay, hydraulic alarm and other components （ such as pressure switches, flow indicator, nozzle ）. The system of long-term work status, network are filled with pressure, when the protected area there is a fire, the environment temperature the nozzles on the temperature sensitive element （ glass ball ） action, the seal assembly off, automatic start-up system, water spray directly to the fire area, and sends alarm signal to the alarm, fire extinguishing the aim, fire control.
ZSFZ type wet alarm valve system principle:
Wet pipe system are filled with pressure water, long-term in a standby state, applied at 4℃ -70 ℃temperature （ and only vertical installation ）. When the protection of fire in the area, environment temperature, nozzle temperature sensitive element （ glass ball sprinkler water ） rupture, fire, and water flow indicator movement indicating fire area, wet alarm valve open the water supply of fire, in which a small portion of water flow to the warning line, drive hydraulic alarm.
Suitable for water extinguishing buildings, usually arranged in fire risk production sites, warehouses, shopping malls, hos, hospitals, theaters, office buildings, high-rise building and garage.

Member function:
Wet alarm valve: only allow water flow sprinkler system and in terms of flow alarm.
Delay: delay hydraulic alarm action time, reduce the pressure fluctuation and the false alarm caused by.
Hydraulic alarm: after starting the system, sound hydraulic driving type alarm device.
Pressure switch: alarm valve, pressure switch on electrical contact.
Alarm valve: bar state for normally open, inspection, maintenance and repair to close the valve.
Test alarm valve : in debugging, maintenance to open the valve, to determine the work of system.
Drain valve: row valve pipe network residual water, to repair or replacement of the sprinkler.
