principle of operation

Closed automatic sprinkler system

Usually, the roof fire water tank is filled with water. In case of fire, when the temperature of the sprinkler reaches a certain temperature (generally 68℃), the sprinkler will be chrome-plated and melted, and the water in the pipeline will automatically spray out under the action of the roof fire water tank. At this point, the wet alarm valve will automatically open, and the pressure switch in the valve will also automatically open. This pressure switch has a signal line interlocked with the fire pump, and the fire pump will start automatically. Then the spray pump supplies the water in the pool to the pipe network through the pipeline, and the whole fire fighting system starts to work.

At the same time, the solenoid valve of deluge valve will be opened, and the linkage spray pump will spray water directly.
