FIRE SUPPRESSION SYSTEM OF PREMISES WITH INCREASED GAS MEDIUM PRESSURE Russian patent published in 2015 - IPC A62C3/00 

FIELD: fire safety.

SUBSTANCE: fire suppression system of premises with increased gas medium pressure, containing a firm sealed tank for storage and feeding of fresh water under pressure on the pipeline into the premises on the centrifugal sprayers, a high pressure air cylinder connected by the pipelines through the air reducer to the tank, the device of limiting the rate of pressure increase, the device of maintaining the differential pressure during decompression, and the control panel with alarm sensors. The air reducer over the membrane cavity is connected by the pipeline to the volume of the protected premises and creates a predetermined differential pressure between the sprayers and the premises, the centrifugal sprayers on the swirlers have spring-loaded movable cylinders, the regulating sections of tangential windows of swirlers, maintaining the required opening angle of the jet of atomised water, the device of maintaining the differential pressure during decompression by the pipelines is connected to the tank and the volume of the protected premises.

EFFECT: improvement of efficiency of the fire suppression system by increasing the intensity of supply of atomised water with an increase of pressure of gas medium during a fire.
