a 'manual

摘要

the invention relates to a fire fighting technology, namely manual were designed to fight fires.and aim at providing the opportunity for full or aerosolized with amending angle torch jet of water or a water screen with maximum u0437u043du0430u0447u0435u043du0438 s range and flow u043eu0433u043du0435u0442u0443u0448u0430u0449u0435u0433u043e vethe business while minimizing hydraulic losses in extinguishing the fire. a "manual" (see para. fig.(1) includes a body with u043fu0435u0440u0435u0445u043eu0434u043du0438u043au043eu043c and coupling head for fire hose u043fu0435u0440u0435u043au0440u044bu0432u043du043eu0435 device management device, into a stream of ra the alignment of the formation of jetsincluding the nozzles with the deflector, which according to the invention the internal surface of the deflector blade is done in a cubical u043fu0430u0440u0430u0431u043eu043bu044b,with the current u043au0440u0438u0432u043eu043bu0438u043du0435u0439u043du043eu0439 deflector is determined by the dependence of the radius;where ri is the radius of the u043au0440u0438u0432u043eu043bu0438u043du0435u0439u043du043eu0439 deflector, mm; li is the current length of the u043au0440u0438u0432u043eu043bu0438u043du0435u0439u043du043eu0439 deflector, mm; b is the thickness of the deflector, mm; c is a parameter, independent of the on u044au0435u043cu043du043eu0439 of stemand for hand guns, is in the range of 1000 - 2000 u043cu043c3.
