Closed foam
The water sprinkler system is an organic combination of the tank pressure proportional mixing device or the balanced proportional mixing device and the water sprinkler system. The mixed liquid is sprayed into the protected area through the nozzle to extinguish the fire.
System composition This system is a joint system that connects the tank pressure proportional mixing device to the automatic water spray system. It mainly consists of a fire pressurization pump unit, a wet alarm valve, a tank pressure proportional mixing device or a balanced foam proportioning device, a signal gate valve, a water flow indicator, a sprinkler head, various control valves, pipes and accessories, as well as fire detection and alarm Control system and other components.
Working Principle When a fire occurs, the closed sprinkler nozzle discharges water, the water in the pipe network flows, the water flow indicator alarm valve acts, an alarm signal is issued, and the alarm signal is fed back at the same time To the control center, start the fire pump and at the same time give
voltage to open the foam liquid automatic control valve. Part of the fire water enters the pipe network and enters the foam tank, squeezes the capsule, and causes the foam liquid to enter the proportional control valve through the control valve. The mixer mixes with another part of water to form a foam mixture, which passes through the pipe network through the closed nozzle to form foam for fire extinguishing.
Application site This system can quickly extinguish oil and
,
mixed fires, and effectively prevent re-ignition. Therefore, it is widely used in parking lots, diesel generator rooms, boiler rooms and other places.
