Изобретение относитс к противопожарной технике и вл етс основной частью вытеснительной системы порошковых огнетушителей .FIELD OF THE INVENTION The invention relates to fire fighting technology and is a major part of the pressure system of powder fire extinguishers.
Известно газогенерирующее устройство, содержащее корпус с твердотопливным зар дом , снабженный крышкой с воспламенителем и зажигаюшим составом и средством дл охлаждени газообразных продуктов сгорани 1.A gas generating device is known, comprising a housing with a solid fuel charge, equipped with a lid with an igniter and igniting composition and means for cooling the gaseous combustion products 1.
Однако в таком устройстве не обеспечиваетс необходимое охлаждение газов, в результате чего происходит спекание порошка, что приводит к снижению эффективности работы устройства.However, such a device does not provide the necessary cooling of the gases, resulting in sintering of the powder, which leads to a decrease in the efficiency of the device.
Целью изобретени вл етс повышение эффективности работы газогенерируюЩего устройства.The aim of the invention is to increase the efficiency of the gas generating device.
Указанна цель достигаетс тем, что средство дл охлаждени газообразных продуктов сгорани установлено по оси корпуса в нижней его части и выполнено в виде цилиндра с продольными газоходными каналами , стенки которых имеют химическое покрытие , разлагающеес при высокой температуре с выделением газа. Химическое покрытие выполнено на основе оксалатов.This goal is achieved by the fact that the means for cooling the gaseous combustion products is installed along the axis of the housing in its lower part and is made in the form of a cylinder with longitudinal flue gas channels, the walls of which have a chemical coating that decomposes at high temperature with evolution of gas. Chemical coating is made on the basis of oxalates.
На фиг. 1 изображено газогенерирующее устройство, продольный разрез, на фиг. 2 - разрез А-А фиг. 1.FIG. 1 shows a gas generating device, a longitudinal section; FIG. 2 - section A-A of FIG. one.
Газогенерирующее устройство содержит корпус 1, в нижней части которого по оси установлено выполненное в виде цилиндра 2 средство дл охлаждени продуктов сгорани . Стенки газоходных каналов цилиндра 2 покрыты химическим веществом 3 на основе оксалатов, которое разлагаетс при высокой температуре с выделением газообразных продуктов. Корпус 1 закрываетс крышкой 4, в которой находитс воспламенитель 5 и состав 6 дл зажигани основного твердотопливного зар да 7. В нижней части корпус 1 выполнен в виде конического сопла с заданным критическим сечением. The gas generating device comprises a housing 1, in the lower part of which axially installed means for cooling the combustion products made in the form of a cylinder 2. The walls of the flue ducts of cylinder 2 are coated with oxalate-based chemical 3, which decomposes at high temperature to release gaseous products. The housing 1 is closed by a lid 4 in which the igniter 5 and the composition 6 are located for igniting the main solid-fuel charge 7. In the lower part the housing 1 is made in the form of a conical nozzle with a given critical section.
15 Легкоразрушима мембрана 8 герметизирует пол.ость зар да 7. Газогенерирующее устройство помещено в стакан 9, который соединен с трубкой 10. Конец трубки 10 расположен в нижней части баллона огнетущите20 л (не показан).15 An easily destructible membrane 8 seals the full capacity of charge 7. The gas generating device is placed in a cup 9, which is connected to the tube 10. The end of the tube 10 is located in the lower part of the balloon, extinguish 20 liters (not shown).
Работа газогенерирующего устройства производитс в следующей последовательности . С помощью специального ударного механизма разбиваетс капсюль-воспламеThe operation of the gas generating device is performed in the following sequence. By means of a special percussion mechanism, the primer is ignited.
