ZSFZ 200 1 2 МПа клапан для влажной пожарной

 The ZSFZ series wet alarmvalve is a checkvalve that only allows water flows unidirectionally and drive the matchingpart to alarm at prescribed pressureand flow. It constitutes the sprinkler system with water flow inductor,pressure switch and sprinklers. This valve is dividedinto two sides by a valve flap. The above side is connected with system pipeline ant the underside is connected with watersupply. The valve flap will open only when the pressure betweenthe two parts reach a certain level.

Working Principle:

The alarm valve is always on aset condition the systemside 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 thenvalve 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 electricsignal and start fire pump and auxiliary fire-fighting equipments to

put out the fire. Waterflow inductor will also work and show the positionof fire.
