The ZSFC dry alarm valve is the water supply control valve for dry sprinkler systems. The pipeline system is usually filled with pressurized gas (also used to monitor the sealing of the pipeline) to keep the valve closed. When the sprinkler head opens, the gas pressure in the pipeline drops rapidly, the valve opens, water enters the pipeline system, and is discharged from the opened sprinkler head, performing the fire extinguishing function.

▌Structural Characteristics and Uses

The ZSFC dry alarm valve is the water supply control valve for dry sprinkler systems. The pipeline system is usually filled with pressurized gas (also used to monitor the sealing of the pipeline network) to keep the valve closed. When the sprinkler head opens, the gas pressure in the pipeline drops rapidly, the valve opens, water enters the pipeline system, and is sprayed out from the opened sprinkler head, performing the fire extinguishing function.

The dry alarm valve operates based on the water pressure before the valve and the pressure of the gas in the pipeline after the valve. The dry alarm valve does not have a delay timer. Installation precautions for the alarm valve: pay attention to the direction of the valve body, flush the pipeline; check the valve disc for repairs or replacements; confirm whether the pressure switch is functioning normally; check for any blockages in the pipeline system; control the installation height and pipeline diameter properly.
