HIGH EXPANSION FOAM FIRE EXTINGUISHING MODULE Russian patent published in 2022 - IPC A62C5/02 A62C31/12 A62C35/02 A62C37/00 

FIELD: fire extinguishment.

SUBSTANCE: module contains a sealed case, filled with water, equipped in the upper part with a gas generating device with a housing and a charge, which is coaxially installed in a sealed container with a foam concentrate, equipped in the lower part with a hole made with the possibility of screwing in a screw having a central hole and pressing a destructible membrane through a washer made of elastomeric material. As a charge, a gas-generating charge is used, the body of which is placed with a gap to the body of the gas-generating device filled with a finely dispersed filter material. The lower part of the module housing is equipped with a neck, at the outlet end of which, by means of a nut, an outlet nozzle equipped with a destructible membrane and a filter element is mounted. A centrifugal injector is mounted on the nozzle, and the lower part of the module body is fastened to a high expansion foam generator by means of rod-shaped elements with an ejection gap, containing a hollow cylindrical body with open ends and foam-generating grids.

EFFECT: invention ensures reproducibility of high expansion ratio of foam on a permanent basis and guaranteed reliable achievement of a functional result.
