Claims (7)

1. Противопожарное устройство, содержащее источник (8, 18) жидкости, насос (1, 11), соединенный с источником жидкости и, предпочтительно, имеющий высокое давление жидкости и сравнительно небольшой поток, и источник (4, 14) газа, соединенный посредством трубопровода (30, 130) с выходной линией (2, 12) насоса для перемешивания газа с проходящей пожаротушащей жидкостью, подводимой к распылительным головкам (3, 13A, 13E, 23), отличающееся тем, что источник газа (4, 14) соединен с выходной линией (2, 12) насоса (1, 11) для получения мелкодисперсного жидкостного тумана, начальное давление заряженного источника (14) газа является более высоким, чем рабочее давление насоса (11), по меньшей мере, одна емкость (15) с жидкостью расположена между и соединена с источником (14) газа и выходной линией (12) насоса (11), причем емкость выполнена с возможностью втекания жидкости из емкости в выходную линию (12) посредством выдавливающего газа из источника газа, а начальное давление заряженного источника газа и объем емкости (15) с жидкостью выбраны по отношению друг к другу таким образом, что при опорожнении емкости (15) с жидкостью давление источника (14) газа, по крайней мере, по-существу такое же, что и рабочее давление насоса (11).1. Fire fighting device containing a source of liquid (8, 18), a pump (1, 11) connected to a liquid source and preferably having a high liquid pressure and a relatively small flow, and a gas source (4, 14) connected by a pipeline (30, 130) with an outlet line (2, 12) of a gas mixing pump with a passing fire extinguishing liquid supplied to the spray heads (3, 13A, 13E, 23), characterized in that the gas source (4, 14) is connected to the outlet line (2, 12) of the pump (1, 11) for obtaining fine liquid fog, the initial the pressure of the charged gas source (14) is higher than the working pressure of the pump (11), at least one fluid container (15) is located between and connected to the gas source (14) and the outlet line (12) of the pump (11) ), and the tank is configured to allow liquid to flow from the tank to the outlet line (12) by means of extruding gas from the gas source, and the initial pressure of the charged gas source and the volume of the tank (15) with the liquid are selected with respect to each other so that when emptying containers (15) with liquid pressed the source of gas (14) is at least substantially the same as the operating pressure of the pump (11). 2. Устройство по п. 1, отличающееся тем, что источник (4, 14) газа выполнен с возможностью перемешивания газа в выходной линии (2, 12) насоса (1, 11) при давлении, по меньшей мере, по-существу таким же высоким, что и давление насоса (1, 11). 2. The device according to claim 1, characterized in that the gas source (4, 14) is configured to mix gas in the outlet line (2, 12) of the pump (1, 11) at a pressure of at least substantially the same high as the pressure of the pump (1, 11). 3. Устройство по п. 1, отличающееся тем, что источник газа содержит множество баллонов (4, 14) со сжатым газом, соединенных параллельно. 3. The device according to claim 1, characterized in that the gas source contains many cylinders (4, 14) with compressed gas connected in parallel. 4.
