  • Product Description
    • Commodity name: Wet alarm valve
    • Commodity ID: ZSFZ150

    1. product introduction

          ZSFZsystem is a commonly used fixed fire extinguishing system, which consistsWet alarm valveDelay, hydraulic alarm and other components (such as pressure switch, water flow indicator, closed nozzle, etc.). The system is in standby working state for a long time, and the pipe network is full of pressure water. When a fire occurs somewhere in the protected area, the ambient temperature height makes the temperature sensitive original (glass ball) on the nozzle move, the sealing component falls off, the system is automatically started, the water is directly sprayed to the fire area, and an alarm signal is sent out to achieve the purpose of alarm, fire extinguishing and fire control.

        This product is used in buildings that can use water to extinguish fires, and is usually installed in production sites, warehouses, hotels, shopping malls, hospitals, theaters, office buildings, high-rise buildings and garages that are in danger of fire.

    2. working principle

          The working principle of the wet alarm valve is to rely on the water pressure of the pipe network system to reduce or increase the opening and closing valve flap. In response to the state, when the water supply pressure fluctuates slightly, the bypass balance pipe makes the upper and lower water pressure balance of the valve flap, and the upper bearing surface of the valve flap is greater than the lower bearing surface, and the valve flap will not open to cause false alarm. When the water pressure on the pipe network system side drops due to spray blasting in a fire, the pressure difference between the water supply side and the system side will open the valve flap and continuously supply water to the open nozzle to extinguish the fire.

          The control ball valve between the alarm port of the wet alarm valve and the delay device must be kept fully open and locked, while the test alarm control ball valve must be closed. When a test alarm is required, remove the locking device of the control ball valve between the alarm port and the delay device and close it. At this time, the alarm test can be carried out by opening the test alarm control ball valve. Immediately restore the two control ball valves to their original state after the test.
