The invention relates to a high-pressure
water curtain fire-extinguishing
system with the functions of
smoke blocking, time
delay and lifesaving, which is characterized by comprising a
water supply pipeline, a horizontal main
pipe and a
smoke sensing and
alarm device, wherein the horizontal main
pipe and the
smoke sensing and
alarm device are connected with the
water supply pipeline, a
water supply valve, a
temperature sensing fire-proof valve and a drainage and gas
inlet valve are connected on the water supply pipeline respectively through pipelines, first elbows which are bent downwards are connected at the two end parts of the horizontal main
pipe respectively, the first elbows are connected with second elbows which are bent downwards and inwards through pipe connecting parts, and spray nozzles are arranged on the second elbows. The high-pressure
water curtain fire-extinguishing
system has the advantages that: when a fire disaster happens, the effects of blocking and absorbing smoke
fog and heat of a high-pressure
water curtain are utilized for isolating a unit from smoke and fire, thereby preventing the smoke
fog and hot air from entering into the unit, keeping
oxygen in the unit and providing
living space and rescue and escape space for trapped staff. Simultaneously, the
system further has the functions of utilizing water
fog for fire extinguishing and effective cooling, thereby effectively solving the difficult problems of
fire prevention, fire extinguishing and rescue of high buildings.
