a 'manual

摘要

the invention relates to a fire fighting technology, namely manual were designed to fight fires, and aims to provide the possibility of a or aerosolized with amending angle torch jet of water or a water screen with the maximum range and the extinguishing medium at a u0438u0437u0430u0446u0438u0438 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 device includes forming the nozzles with the deflector, which according to the invention the internal surface of the deflector blade is v de 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 barrel and hand guns, is in the range of 1000 - 2000 u043cu043c3.
