发明名称 CHAMBER OF LOW-FACTOR FOAM
摘要 FIELD: fire-fighting equipment. ^ SUBSTANCE: invention relates to fire-fighting equipment, namely to systems of fire extinguishing in reservoirs with highly inflammable liquids (HIL). In chamber of low factor foam, containing foam generator, connected with cylindrical body, which has detachable bottom and discontinuous preventive membrane, simultaneously isolative cavity of body with foam generator from internal cavity of reservoir. Into internal volume of reservoir opens coaxially located with cylindrical body cylindrical tip, which ends with gap orifice, having nozzles of rectangular section, forming fantail foam jet, section of one of nozzles being in plane, parallel to axis of cylindrical tip and perpendicular to axis of foam generator, sections of other nozzles being located in plane, inclined to plane of connecting flange and being symmetrical with respect to vertical axis of cylindrical tip. Foam generator contains cylindrical body with flanges on butt ends, in one of which placed is nozzle for supply of foam former water solution and in lateral surface of body - branch-pipe for air supply, and placed inside the body opposite the nozzle mixing chamber. ^ EFFECT: increase of efficiency of foam generator, producing foam of low factor at boundary values of foam generator operation conditions. ^ 3 dwg
