Deluge alarm valve is a key component of automatic sprinkler system, which is mainly used for the protection of industrial fire. This kind of valve starts quickly when a fire occurs and sprays a large amount of water mist through two outlets to control the development of the fire. Compared with the traditional deluge alarm valve with only one water outlet, the deluge alarm valve with two water outlets can provide a wider coverage, which is suitable for glass curtain wall, fire shutter, evacuation channel and other places.
working principle of the deluge alarm valve
The working principle of the deluge alarm valve is based on the hydraulic force. Under normal conditions, water flows into the upper side of the control diaphragm from the water inlet of the valve body and generates hydraulic force through the inner channel of the conductor and the valve element. The control diaphragm moves downward under the action of water pressure and spring, and the sealing ring contacts the valve base to form a sealing state. When it is necessary to spray water, the water pressure on the control diaphragm decreases, the valve element moves upward and opens by the push of the water inlet pressure. The water is discharged from the outlets on both sides of the valve for fire extinguishing.
Core functions
1. Quickly respond to fire extinguishing
Diaphragm drive: By controlling the deformation of the diaphragm through water or air pressure, it can achieve millisecond level rapid opening, which is faster than traditional mechanical valves.
Fully open discharge: After the valve is opened, all nozzles spray water simultaneously, forming a full coverage fire extinguishing effect.
2. Automatic alarm linkage
Hydraulic alarm bell: When the valve is opened, the water flow triggers the alarm bell, which sounds an alarm on site.
Pressure switch: send electrical signals to the fire control room, linkage fire pump, foam system, etc.
3. Anti misoperation design
Hydraulic balance chamber: prevents accidental triggering of water pressure fluctuations.
Locking mechanism: Some models can be manually locked to prevent accidental activation.
4. Adapt to complex environments
Corrosion resistance: diaphragm material, suitable for corrosive environments such as chemical and marine industries.
Anti pollution: No mechanical friction parts, not easily stuck due to impurities.
Main function
1. Quickly extinguish fires in high-risk areas
Applicable scenarios:
Petrochemical storage tank area
Power facilities
Transportation hub
Military/Aerospace Industry
2. System linkage control
Automatic start: linked with fire detectors to achieve unmanned firefighting.
Multi system cooperation: it can link foam proportioner, smoke exhaust system, emergency lighting, etc.
3. Low maintenance and high reliability
No mechanical wear: The diaphragm has a lifespan of over 10 years and low maintenance costs.
Self cleaning design: automatic flushing of valve chamber by water flow to reduce sediment blockage
