ZSFZ type wet alarm valve

The wet alarm valve system is a universal fixed fire extinguishing system, which consists of a wet alarm valve, a delayer, a hydraulic alarm bell and other components (such as pressure switches, water flow indicators, sprinklers, etc.). The system is in standby mode for a long time, and the pipe network is full of pressure. When a fire occurs somewhere in the protection area, the ambient temperature rises. The temperature-sensitive element (glass ball) on the nozzle head moves, the sealing component falls off, and the system automatically starts to release the water. Spray directly to the fire area and send out an alarm signal to achieve the purpose of alarm, fire extinguishing and fire control.
Principle of the wet alarm valve system:
The wet system pipe network is filled with pressure water and is in a standby working state for a long time. It is suitable for ℃ and ℃ ambient temperatures (and can only be installed vertically). When a fire occurs in the protected area, the ambient temperature rises, the temperature sensitive element (glass ball) of the sprinkler head breaks, and the sprinkler head discharges water to extinguish the fire. At the same time, the water flow indicator moves to indicate the fire area, and the wet alarm valve opens to supply water to extinguish the fire, and a small part of the water flows to Alarm pipeline drives hydraulic alarm.
Buildings suitable for water fire extinguishing are usually installed in production sites, warehouses, hotels, shopping malls, hospitals, theaters, office buildings, high-rise buildings, garages and other places with fire risks.
