ZSFZ150-1.6G wet alarm valve
Category:
Wet alarm valve
- Product Description
-
The wet alarm valve device is in a constant state of readiness, with the system side filled with water under working pressure. When a fire occurs in the control area of the automatic sprinkler fire extinguishing system, the heat-sensitive element in the closed sprinkler heads on the system network is heated and bursts, automatically spraying water. The system-side pressure of the wet alarm valve decreases, and under the action of the pressure difference, the valve automatically opens, and the water from the supply side flows into the system side to replenish the network, causing the entire network to enter an automatic water spray fire extinguishing state. At the same time, a small amount of water flows to the delay device and the hydraulic alarm through small holes on the seat ring. Under certain pressure and flow conditions, the hydraulic alarm sounds an alarm. The pressure switch converts the pressure signal into an electrical signal, starting the fire pump and auxiliary fire extinguishing equipment to replenish water and extinguish the fire. The network equipped with a water flow indicator also operates accordingly, outputting an electrical signal to allow the system control terminal to promptly detect the area where the fire occurred, achieving the purpose of automatic water spray fire extinguishing and alarm.
Working principle
The wet alarm valve device is in a constant state of readiness, with the system side filled with water under working pressure. When a fire occurs in the controlled area of the automatic sprinkler fire extinguishing system, the heat-sensitive element in the closed sprinkler heads on the system network is heated and bursts, automatically spraying water. The pressure on the system side of the wet alarm valve decreases, and under the action of the pressure difference, the valve automatically opens, and the water from the supply side flows into the system side to replenish the network, making the entire network in an automatic sprinkler fire extinguishing state. At the same time, a small amount of water flows to the delay device and the hydraulic alarm bell through the small holes on the seat ring. Under certain pressure and flow conditions, the hydraulic alarm bell sounds an alarm, and the pressure switch converts the pressure signal into an electrical signal to start the fire pump and auxiliary fire extinguishing equipment for water replenishment and fire extinguishing. The pipeline equipped with a water flow indicator also operates accordingly, outputting an electrical signal to allow the system control terminal to promptly detect the area where the fire occurred, achieving the purpose of automatic sprinkler fire extinguishing and alarm.
