Principle of operation
The invention relates to an alarm valve station for a fire alarm system, which has the working principle and function that fire-fighting water storage in a building fire-fighting pipeline can be controlled to flow towards a water-spraying fire-extinguishing nozzle in a one-way mode according to the fire condition, and is a timely and efficient fire-fighting valve. The valve station can be opened instantly, so that water enters the connecting pipe 5 and enters a water distribution network of the water supply side control valve 8, a valve chamber of the deluge valve is divided into a compensator 1, the water supply side control valve 8 and a system measurement and control valve 9, the compensator 1 is connected with the pipeline 2, and a filter 10 is arranged in the middle. The pressurized water in the pipe 2 pushes the diaphragm of the water supply side control valve 8 and then pushes the driving lever to tighten the flap locking lever, thereby generating torque and locking the flap to the valve seat. The valve flap prevents pressurized water from entering the upper chamber of the lower chamber. In fire fighting, the moment of force exerted by the drive lever on the disc lock lever is less than the water supply pressure exerted on the disc due to the control chamber being vented, so that the disc opens and water supply enters the conduit 2. The system adopts the rain valve and the alarm system, the spray head is closed, water does not exist in the pipeline 2 generally, the pre-charging can be carried out once the alarm is given, and the system can prevent false alarm or frost crack from being carried out by a dry system to a wet system, so that the system is particularly suitable for waterproof places. The sprinkling range of the rainwater system is controlled by a rainwater valve, and large-area water is sprayed immediately after the system is started. Is suitable for special dangerous places needing large-area sprinkling and quick fire extinguishing. In addition, the raindrop valve also plays an important role as an alarm control valve in a water-spraying fire-extinguishing system.
