GAS-WATER FIRE-EXTINGUISHING SYSTEM Russian patent published in 2018 - IPC B05B1/20 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to fire fighting equipment and can be used in industrial and civil facilities with increased fire danger for fires control. Gas-water fire-extinguishing system contains a network of main and distribution pipelines with sprinklers installed on them. Main, and each of the distribution pipelines, consists of pipelines supplying water and gas. Water supply to the main pipeline is carried out from the pneumatic tank through the pipeline. Gas supply – through the pipeline from the gas distribution station, including cylinders with compressed gas and two reducers, one of which regulates the gas pressure in the main network, and the other is connected by the pipeline to a lid of the pneumatic tank to create water pressure in the main network. To start the system, an automatic microprocessor station is installed in the gas supply line between the pipeline connecting the cylinders to the compressed gas, and in front of the reducers, which is connected by a communication link to the fire detection sensors installed in the room, and the drencher is designed as a two-phase sprinkler with a central water supply and a lateral gas supply.

EFFECT: invention makes it possible to increase the efficiency of fire extinguishing by introducing a sprinkler that excludes turbulization of the extinguishing composition flow.
