UNIVERSAL INSTALLATION FOR COMBINED FIRE EXTINGUISHING WITH AIR-MECHANICAL FOAM OF MEDIUM EXPANSION RATIO, AIR-MECHANICAL FOAM OF LOW EXPANSION RATE, SPRAYED AND DISPERSED WATER OR QUICK-HARDENING FOAM BASED ON FOAMED SILICA GEL Russian patent published in 2024 - IPC A62C5/02 A62C31/05 A62C31/12 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to fire-fighting equipment, namely to a combined fire extinguishing installation made with possibility of separate generation and separate supply under pressure of either medium expansion air-mechanical foam, or low expansion air-mechanical foam, or sprayed and dispersed water, or quick-setting foam based on foamed silica gel, wherein the installation comprises a housing, a mesh cassette arranged inside the housing, located in front of the mesh cassette nozzles for supplying fire extinguishing agents to the mesh cassette, barrel with an ejector mixer arranged inside the barrel with an ejection suction branch pipe inside the barrel of the fire extinguishing agent component, pipelines for supplying fire extinguishing agents to the nozzles and into the barrel and valves for opening/closing the pipelines of the fire extinguishing agents, wherein the mesh cassette is made of coaxially installed one inside the other inner, intermediate and outer annular rims and two meshes arranged with a gap relative to each other, one of which is fixed by its edges in the gap between the mating side surfaces of the outer and intermediate rims, and the other mesh is fixed by its edges in the gap between the mating side surfaces of the intermediate and inner rims, in the inner rim there is an annular holder installed and fixed by means of flat ribs parallel to the direction of movement in the housing of the fire extinguishing agent with a through hole for placing the barrel in it, in the meshes there are holes coaxial and commensurate with the through hole of the holder with fixation of the edges of the meshes on the holder by means of annular washers and screws, and the barrel is placed in the through hole of the holder in the mesh cassette and is connected to the means for supplying fire extinguishing agents to it.

EFFECT: disclosed is a universal combined fire extinguishing installation.
