ZSFC dry alarm valve

Overview

The ZSFC dry alarm valve is the water supply control valve of the thousand type sprinkler system. The valve is normally closed with pressurized  gas in the pipeline system (also used to monitor the sealability of the pipe network). When the nozzle is opened, the gas in the pipe network drops  rapidly, the valve opens, the water enters the pipe network system and is ejected from the open sprinkler head to perform the fire extinguishing function.

ZSFZ wet alarm valve

Overview

The ZSFY system is a universal automatic sprinkler system, which consists of wet alarm valve, retarder, hydraulic alarm and other components  (pressure switch, flow indicator, sprinkler). The system is in the working condition for a long time, and the pipe network is filled with pressure water.  When there is a fire somewhere in the protected area, the ambient temperature rises and the heat sensitive element (glass ball) on the nozzle moves,  the sealant component is dropped, the system is started automatically, the water is sprayed directly into the area where the fire occurs, and the alarm  signal has reached the purpose of alarm, fire extinguishing and fire control. The wet alarm valve is widely used in high-rise buildings, hospitals, hotels, offices, shopping malls and warehouses, factories and underground  works because of its stable working performance, high fire extinguishing efficiency, sensitive operation, simple maintenance, long reliable service life,  etc.
