Title (EN) FIRE-EXTINGUISHING EQUIPMENT
(FR) APPAREIL ANTI-INCENDIE
Abstract:
(EN) The present invention relates to a fire-extinguishing equipment that includes at least the following members: a vessel (1) containing a fire-extinguishing substance; a tank (2) of pressurised gas; flexible pipes (5, 6, 7) for connecting the vessel and the tank to each other as well as to a device (4) that generates a directed flow of the fire-extinguishing substance mixed with the working gas; and a pressure regulator (3) for the working gas. The device (4) comprises a mixing chamber (8) for the fire-extinguishing substance and the gas, wherein said chamber has a gas-dynamic nozzle (11) mounted at its outlet. The length of the profiled channel in the nozzle (11) is equal to at least twice the diameter of said nozzle channel at its smallest section. The vessel (1) and the tank (2) may be fitted in a backpack. The nozzle may be made in the shape of ring and fitted with an annular channel for feeding additional working gas before the minimal section of its own channel. The central body of the annular nozzle may be made in the shape of a cone with its tip directed towards the nozzle inlet.
(FR) L'invention concerne un appareil anti-incendie qui comprend au moins les éléments suivants: un récipient (1) avec une substance destinée à la lutte anti-incendie; une bouteille (2) de gaz comprimé; des tubes flexibles (5, 6, 7) qui relie le récipient et la bouteille entre eux ainsi qu'à un dispositif (4) servant à créer un jet dirigé de substance anti-incendie mélangée au gaz de travail; et enfin, un régulateur (3) de pression du gaz de travail. Le dispositif (4) comprend une chambre de mélange (8) de la substance anti-incendie et du gaz, une buse à dynamique des gaz (11) étant installée à la sortie de ladite chambre. La longueur du canal profilé de la buse (11) est égale à au moins deux fois le diamètre de la section minimale du canal de buse. Le récipient (1) et la bouteille (2) peuvent être installés dans un système dorsal. La buse peut avoir une forme annulaire et être pourvue d'un canal annulaire qui est disposé en avant de la section minimale du canal de buse et et qui assure une alimentation supplémentaire en gaz de travail. Le corps central de la buse annulaire peut avoir la forme d'un cône dont le sommet est orienté vers l'entrée de la buse.
