MOBILE FIRE EXTINGUISHING INSTALLATION WITH FOAM GENERATION BY COMPRESSION METHOD Russian patent published in 2018 - IPC A62C27/00 

FIELD: fire safety.

SUBSTANCE: invention relates to the fire fighting equipment, namely to the ground fire-fighting vehicles with the foam generation by compression method. Mobile fire extinguishing installation with foam generation by compression method comprises mixing chamber, to which outlet the foam supply device to the fire center is connected, and by the pipes connected to the mixing chamber inlet the water supply system, including the water supply pump and the water supply pump drive, foaming concentrate supply system, including the foam pump and the foam pump drive, as well as the air supply system, including the air compressor and the air compressor drive. According to the invention, connecting the water supply pump and the mixing chamber the water supply pipeline is provided with the water flow meter, with electric driven throttle valve and check valve, as well as the throttle valve electronic control unit, at that, the throttle valve control unit input is electrically connected to the water flow meter output, and the throttle valve control unit output is electrically connected to the throttle valve electric drive input.

EFFECT: achieved by the claimed invention technical result consists in the possibility of obtaining in the automatic mode of the necessary by the pressure and density foam with the foam variable back pressure at the mobile extinguishing installation output, as a result of the pressure hoses changing hydraulic resistance and the foam rise geometric height along these hoses, while achieving the installation greatest efficiency due to the stable foam supply mode, which is maintained automatically, regardless of the possible variations in the of the pressure line characteristics at the mobile fire extinguishing installation output.
