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
