Description
Изобретение относитс к противопожарной технике, в частности к устройствам, обеспечивающим доставку огнетушащего состава в зону горени .The invention relates to fire fighting equipment, in particular, to devices that deliver a fire extinguishing composition to the combustion zone.
Цель изобретени - упрощение конструкции и повыщение надежности.The purpose of the invention is to simplify the design and increase reliability.
На фиг. 1 представлено устройство, разрез , до срабатывани ; на фиг. 2 - то же, после срабатывани .FIG. Figure 1 shows the device, section, before actuation; in fig. 2 is the same after triggering.
Устройство содержит корпус 1 с основанием 2, закрытым разрушаемой мембраной 3, поршнем 4 дл вытеснени огнетущащего состава 5, выполненным в виде эластичной газопроницаемой оболочки, кра ми закрепленной по периметру основани 2 корпуса 1. Оболочка имеет форму внутренней поверхности корпуса. На корпусе напротив основани расположена камера 6 сгорани с пирс- побудителем 7 и перфорированным диском 8.The device comprises a housing 1 with a base 2 closed by a ruptured membrane 3, a piston 4 for displacing the fire-extinguishing composition 5, made in the form of an elastic gas-permeable shell, with edges fixed along the perimeter of the base 2 of housing 1. The shell has the shape of the inner surface of the housing. A combustion chamber 6 with a piercing driver 7 and a perforated disk 8 is located on the housing opposite the base.
Устройство работает следующим образом.The device works as follows.
При поступлении командного электрического импульса срабатывает пиропобудительWhen a command electric impulse arrives, the actuator triggers
7 и образующиес гор чие газы из камеры 6 сгорани поступают через отверсти перфорированного диска 8 в полость корпуса 1. Проника через газопроницаемую оболочку 4, продукты сгорани зар да пиропобудите- л 7 поступают в поры между частицами порошка и повышают давление во всей полости корпуса 1. При достижении расчетной величины давлени проис.ходит разрушение герметизирующей мембраны 3 и огнетушащий состав 5 начинает поступать в полость защищаемого аппарата. Дальнейщее поступление газов из камеры 6 сгорани обеспечивает выброс огнетущащего состава 5 с одновременным перемещением эластичной га- зопроницаемой оболочки 4. Поскольку кра оболочки 4 жестко закреплены по все.му периметру основани 2, под воздействием перепада давлени оболочка 4 выворачиваетс внутренней поверхностью наружу, обеспечива полный выброс огнетущащего состава .7 and the resulting hot gases from the combustion chamber 6 enter through the apertures of the perforated disk 8 into the cavity of the housing 1. Penetration through the gas-permeable shell 4, the combustion products of the charge of the pyrobud 7 enter the pores between the powder particles and increase the pressure throughout the cavity of the housing 1. When the calculated pressure value is reached, the sealing membrane 3 is destroyed and the fire extinguishing composition 5 begins to flow into the cavity of the protected device. The further flow of gases from the combustion chamber 6 ensures the release of the fire-extinguishing composition 5 with simultaneous movement of the elastic gas-permeable casing 4. Since the edges of the casing 4 are rigidly fixed along the entire perimeter of the base 2, under the pressure differential the casing 4 is turned inside out to give a full ejection fire extinguishing composition.
