Zsfz 80/100/150/200 Wet Type Alarm Valve for Fire Sprinkler System
Wet Alarm Check Valve Introduction:
The ZSFZ wet alarm valve is a one-way valve that only allows water
to flow into the water spray system
in one direction and alarms at a specified flow rate. and drive the
matching part to alarm at prescribed
pressure and flow. It constitutes the sprinkler system with water
flow inductor, pressure switch and
sprinklers. This valve is divided into two sides by a valve flap.
The above side is connected with system
pipeline ant the underside is connected with water supply. The
valve flap will open only when the pressure
between the two parts reach a certain level.

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.
