Description:

1. The pre action valve and deluge valve is a deluge valve below and a wet alarm valve above. When in the serving state, the system side is filled with pressurized gas, and the lower deluge valve relies on the pressure chamber or diaphragm cavity to control the pressure on the source side.

2. In the event of a fire, two independent smoke detectors form an "and" logic alarm signal, and the logic controller sends a control signal to open the solenoid valve on the pre-action alarm valve group (or open the manual quick opening valve), and the pressure chamber is relieved. After the flow of fire water in the pipe network, trigger the flow switch and low-pressure pressure switch, trigger the pressure switch and hydraulic alarm bell after pressurized water enters the alarm pipeline, and open the rapid exhaust valve at the same time, and the whole system completes the exhaust water filling within 1min or 2min.

3. After completing the exhaust flushing, the pre-action system is converted into a wet system, and as the fire temperature reaches the design temperature of the hot melt element of the nozzle, the water is directly released to fight the fire after the nozzle element is ruptured.
