1, Introduction
ZSFZ alarm valve is a non return valve which sends alarming on setÂ
point  of  flow  rate.  Installed  with  pressure  switch,  water  flow  indicator,Â
sprinklers, it becomes a automatic water extinguishing system. The pipeÂ
line  is full of  pressured  water,  if  there  is  a fire  accident,  the fire  zoneÂ
sprinkler  glass bulb  will burst due to heat. So the system automaticallyÂ
operate and watering the fire zone. The alarm signaling is also sent.
ZSFZ alarm valve is  working  at temperature from  4ºC  to 70ºC  andÂ
the amount of sprinklers for a system shouldn't more than 800 pcs
2, Structure and Working Principle
ZSFZ  alarm  valve  is  assembled  by  alarm  valve,  time  delay  unit,Â
water force bell, pressure switch, draw off valve etc.
2.1 alarm valve is component by valve body, ring and valve clack. TheÂ
valve has top chamber and bottom chamber. Top chamber is connectedÂ
with  pipe  line  and  bottom  chamber  is  connected  with  water  supply.
There are many small holes to time delay unit, but there are normallyÂ
sealed by valve clack and the water to water force bell is cut off.
2.2 time delay unit is a cylinder container with inlet and outlet ports. DueÂ
to the water pressure is not stable, the valve clack may open and closeÂ
quickly,  there  will  be  some  water  entering  time  delay  unit  and  drainÂ
through the bottom. It prevents the false alarm due to water pressureÂ
change.
2.3 water force bell is drive by water power. When the valve clack open,Â
the water fill the time delay unit and go to bell. Drive by the water stream,Â
the bell clapper hitting the bell sending alarm.
