Pump type perfluorohexanone spray fire extinguishing device
The closed foam-water spray device 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 connects the tank pressure proportional mixing device to the automatic water spray system to form a joint 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 breaks out, the closed sprinkler nozzles will discharge water, the water in the pipe network will flow, the water flow indicator alarm valve will act, and an alarm signal will be sent out. At the same time, the alarm signal will be fed back to the control center, the fire pump will be started and the foam liquid automatic control valve will be opened. Part of the fire water enters the pipe network and enters the foam tank, squeezing the capsule so that the foam liquid enters the proportional mixer through the control valve and 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 areas: This system can quickly extinguish oil and Class A and B mixed fires, and effectively prevent re-ignition. Therefore, it is widely used in parking lots, diesel generator rooms, boiler rooms and other places.
