INSTALLATION OF MODULAR FIRE-FIGHTING EQUIPMENT Russian patent published in 2011 - IPC A62C35/00 

FIELD: fire-fighting equipment.

SUBSTANCE: container with fire-fighting agent is attached with brackets to building structure of the premises and is equipped with a devise of discharge of gas phase, combined with measuring probe for extinguishing liquid, and stop-starting device of electromagnetic type, which is connected with a tube for input of the fire-extinguishing liquid into the foam generator, which includes the output nozzle with a conical diffuser chamber and the centrifugal swirler of compressed air flow and fluid flow, made in the form of a cylindrical sleeve within which a cylindrical chamber for mixing and formation of air-mechanical foam is coaxially located to the outer surface of the sleeve. Output of the mixing chamber is connected to an input of a coaxially placed conical diffuser chamber and the compressed air enters the centrifugal swirler and mixing chamber through the duct of a turbocharger, a signal for which comes to switch-on together with a signal to activate the automatic stop-start device from the control unit of fire-extinguishing system, and to provide automatic fire-fighting mode LSD and turbocharger are connected electrically via a control unit to smoke detectors. The cylindrical sleeve is provided with an axial throttling channel connected to a fluid supply tube, formed in its end wall, and contains at least three tangentially directed channels formed in its side wall. Submission of air-mechanical foam is carried out into the central conduit, and then to a nodal point of the distribution network, and through the distribution network - to all the irrigators.

EFFECT: improving efficacy of fire-fighting.
