Abstract

FIELD: fire prevention, in particular, pulsed-action powder means of fire-fighting. SUBSTANCE: device for powder fire-fighting uses a cylindrical casing with a bottom filled with fire- extinguishing powder, unit with a pyrotechnical charge and igniter located in the bottom and separated from powder by a piston, and a cover sealing the casing on the side of the open end face. The piston has perforated holes, whose centers are arranged symmetrically, uniformly on circumferences concentric relative to the piston axis. The total area of perforated holes makes up 3.5 to 25% of the piston area. The specific value of the total area of perforated holes is selected proceeding from the required distance of ejection of dispersed flow of fire-extinguishing powder. EFFECT: enhanced efficiency. 1 cl, 2 dwg

Изобретение относится к противопожарной технике, а именно к порошковым средствам пожаротушения импульсного действия. Устройство порошкового пожаротушения содержит наполненный огнетушащим порошком цилиндрический корпус с днищем, узел с пиротехническим зарядом и воспламенителем, размещенный в днище и отделенный от порошка поршнем, и крышку, герметизирующую корпус со стороны открытого торца. Поршень имеет перфорационные отверстия, центры которых расположены радиально-симметрично, равномерно на концентрических, относительно оси поршня окружностях. Суммарная площадь перфорационных отверстий составляет 3,5-25% площади поршня. Конкретное значение суммарной площади перфорационных отверстий выбирается, исходя из требуемой дальности выброса диспергированного потока огнетушащего порошка.The invention relates to fire fighting equipment, and in particular to pulsed powder fire extinguishing agents. The powder fire extinguishing device comprises a cylindrical body filled with a fire extinguishing powder with a bottom, a unit with a pyrotechnic charge and an igniter, located in the bottom and separated from the powder by a piston, and a cover that seals the case from the open end. The piston has perforations, the centers of which are located radially symmetrically, evenly on concentric circles relative to the axis of the piston. The total area of the perforation holes is 3.5-25% of the piston area. The specific value of the total area of the perforation holes is selected based on the required ejection range of the dispersed extinguishing powder stream.
