The Induction of Flange Type Wet Alarm Check Valve
When the fire fighting system is in standby mode, the inside of the fire fighting pipeline is filled with pressurized water. The water and the wet alarm valve are blocked by a fusible ball. There is no water pressure in the alarm valve, and the natural alarm valve The valve disc is closed, and the hydraulic alarm bell will not sound the alarm. Once a fire occurs in the area, the temperature in the environment will rise sharply, which will cause the fusible material ball to break and rupture! The pressure water is to break through the barrier and spray out through the nozzle, so that the disc of the alarm valve will be affected by the pressure difference The alarm will start to work and make an alarm sound. At the same time, the valve flap will be lifted to open the water flow channel, and the water supply system will send water to the area to extinguish the fire.
