GAS-LIQUID SPRINKLER Russian patent published in 2022 - IPC A62C31/02 A62C31/05 

FIELD: fire protection.

SUBSTANCE: invention relates to the field of fire extinguishing, namely to devices providing the supply of extinguishing liquid to the ignition source. The gas-liquid sprinkler contains a round housing with a gas collector cavity covering the liquid collector, a nozzle for supplying extinguishing liquid to the liquid collector and a gas supply pipe to the gas collector cavity installed on one side of the housing, supersonic nozzles communicating with the gas collector cavity installed on the other side of the housing and channels for supplying extinguishing liquid communicating with the liquid collector. At the same time, supersonic nozzles and fire extinguishing fluid supply channels are uniformly arranged around the axis of the housing and installed in several rows on the toroidal surface of the housing with the radius of the forming circle R, the axis of rotation of which coincides with the axis of the housing. In each row, the axes of the fire extinguishing fluid supply channels are located between the axes of supersonic nozzles. The supersonic nozzles are made in the form of a cone expanding in the direction of the outflow of gas to the center of the forming circle of the toroidal surface. These axes intersect the center of the forming circle of the toroidal surface, and also lie in the same plane with the axis of the body.

EFFECT: increase in the efficiency of fire extinguishing by increasing the concentration of droplets of small-sized extinguishing liquid sprayed by interacting supersonic gas jets.
