Automatic sprinkler system is recognized as the most effective self-rescue fire-fighting facilities in the world, the most widely used, the largest consumption, and has the advantages of safety, reliability, economic and practical, high success rate of fire extinguishing.
Sprinkler system has been used for decades in our country. With the development of Chinese economy, the production and application research of sprinkler system will be greatly developed.
Automatic sprinkler system is a kind of fire-fighting facilities which can automatically open the sprinkler head and send out the fire signal at the same time. Different from the hydrant system, the hydrant fire extinguishing system can not automatically extinguish the fire, and the fire extinguishing personnel are needed to extinguish the fire, while the main feature of the automatic sprinkler system is that the water is sent to the pipe network through the pressure equipment, to the nozzle with thermal sensitive elements.The sprinkler head automatically opens in the thermal environment of the fire to open the sprinkler to extinguish the fire. Usually, the cover area under the sprinkler head is about 12 square meters.
Dry automatic sprinkler system is a normally closed sprinkler system. In the pipe network, there is usually no flushing, only pressurized air or nitrogen. When a fire breaks out in the building, the normally closed sprinkler head is opened. When the sprinkler head is opened, the gas is discharged first, and then the water is flushed to extinguish the fire.
There is no flushing in the pipe network of dry automatic sprinkler system at ordinary times, so it has no impact on the decoration of the building and the ambient temperature. It is suitable for the heating period is long but there is no heating in the building. However, the extinguishing efficiency of the system is not as high as that of the wet system.
