FIELD: fire-prevention facilities.SUBSTANCE: invention relates to fire fighting equipment. Gas-water fire-extinguishing system comprises a network of main and distribution pipelines with sprayers. The 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. The gas is supplied through the pipeline from gas distribution station, which comprises cylinders with compressed gas and two gears. One of the gears regulates the gas pressure in the main pipeline, and the other is connected by the pipeline to the cover of the pneumatic tank to create water pressure in the main pipeline. To start the system the automatic microprocessor plant is provided, which is installed in the gas-supply line between the pipeline. The pipeline connects the cylinders with compressed gas. In front of the gears an automatic microprocessor plant is mounted, which is connected by the communication line to the sensors of fire detection. The sensors are mounted in the premises.EFFECT: increased efficiency of fire-fighting through the insertion of the sprayer which eliminates turbulence of fire-extinguishing mixture flow.1 cl, 5 dwg |
