Audited Supplier Sprinkler System Wet Valve, Wet Alarm Check Valve (ZSFZ Serious )
Working Principle:
The alarm valve is always on a set condition the system side is full of pressurized water. The heat sensitive component on the sprinkler will blast and spray automatically when there is fire somewhere. Thus the pressure at system side will reduce and then valve flap opens because of pressure difference. One hand the water supplied to system side, on the other hand a small part of water flows to delayer and reach water motor alarm finally to make it alarm. The pressure switch turns pressure signal to electric signal and start fire pump and auxiliary fire-fighting equipments to put out the fire. Water flow inductor will also work and show the position of fire.
Delayer:
The delayer is a cylindrical water storage tank that with inlet and outlet. Because that the pressure of system side will fluctuate that the valve flap will open at a moment but will close right away. In order that the water motor alarm make misinformation, the delayer store the water to buffer time.
Pressure Switch:
Pressure switch turns the pressure of water into electrical signal and it was installed above the delayer. When the system is started, pressure in the alarm pipeline reaches the motion level of the switch and the contact will close or open, turning water pressure into electrical signal.
