The ZSFZ wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction, and drives the supporting parts to alarm under the specified pressure and flow. The wet automatic sprinkler system composed of water flow indicator, pressure switch and sprinkler is a kind of fixed fire extinguishing system with extremely wide application. The pipe network of the system is filled with clean water under a certain pressure all year round, and it is in a waiting state for a long time.
When a fire occurs somewhere in the protected area, the ambient temperature in the area rises, and the organic solution in the heat sensitive element (glass ball) of the sprinkler Thermal expansion generates a large internal pressure until the glass bulb shell is broken, which turns on the nozzle to spray water, and automatically activates the entire system to send out sound and light alarm signals to achieve the purpose of fire alarm, fire control, and fire suppression.
