HIGH PRESSURE FIRE HOSE BARREL Russian patent published in 2023 - IPC A62C31/02 A62C31/28 

FIELD: fire-fighting equipment.

SUBSTANCE: manual fire nozzle designed to form and direct a compact or sprayed jet, as well as to shut off the supply of the fire extinguishing mixture. The fire nozzle contains a main hollow body and a means for shutting off the flow of fire extinguishing liquid, as well as a manifold installed in the internal cavity of the body, made with one inlet hole connected to a high-pressure hose, and with two outlet holes, with a flange-mounted coupling installed in each outlet hole, wherein a means for shutting off the flow of fire extinguishing liquid made in the form of a ball valve, is installed on each of the said couplings, and each of the said couplings is configured to connect the manifold and the ball valve without rotating them, while nozzles made in this way are installed on each said ball valve that one nozzle is configured to provide a continuous stream of fire extinguishing liquid, and the second nozzle is configured to provide a finely atomized jet of fire extinguishing liquid, and the manifold is made of a cylindrical body and a manifold cover, and an O-ring is additionally installed between the cover and the manifold body.

EFFECT: improved efficiency of fire extinguishing, accelerated switching of modes, while ensuring the compactness of the device.
