The working principle of fire sprinkler system

closed fire sprinkler system:

At ordinary times, the roof fire water tank is filled with water. When a fire occurs, the nozzle is chrome plated and melted after the temperature reaches a certain temperature (usually 68°C). The water in the pipe is automatically sprayed out under the action of the water pressure of the fire water tank. At this moment, the wet alarm valve is automatically opened, and the pressure switch in the valve is automatically opened. The pressure switch has a signal line interlocking with the fire pump, and the pump is automatically started. Then the spray pump provides the water in the pool to the pipe network through the pipe, and the whole fire fighting system starts to work.

open fire sprinkler system:

The system is equipped with a smoke sensor to detect the smoke. When the smoke reaches a certain concentration, the smoke sensor will give an alarm. After confirmation by the host, it will feed back to the sound and light alarm to warn people with sound or flashing lights. The smoke prevention and exhaust fan will be started in linkage to start smoke exhaust. At the same time, the solenoid valve of the deluge valve will be opened, and the open nozzle will spray water directly in linkage with the spray pump.
