DRY-CHEMICAL EXTINGUISHING MODULE

FIELD: fire-prevention facilities.SUBSTANCE: invention relates to fire fighting technology, namely, dry-chemical extinguishing modules, which are universal fire-extinguishing means. The dry-chemical extinguishing module comprises a housing 1, a gas generator 3, a nozzle orifice 8, a destructible membrane 9. The housing 1 is equipped with the dry chemical powder. The gas generator 3 is mounted at the upper part of the housing 1 and is equipped at the lower part with the aerator 4. At the upper part the gas generator 3 is connected to the electric triggering element. The nozzle orifice 8 is made in the form of a hollow cylindrical nozzle and placed in the neck 7 of the housing bottom with a gap. The destructible membrane 9 is pressed with the swivel nut 11 to the neck 7 of the bottom of the housing 1. The lateral surface of the aerator 4 is equipped with the holes 5 which are covered with the breaking elements. The end face of the nozzle orifice from the side of the membrane is equipped with a flange 12, and the end face facing the gas generator is equipped with curved holes 15. Each fragment 16 of the end face is in the place of the hole made and bent inside the nozzle orifice. And the connection with the end face is maintained in the part of its perimetre which coincides with the conventional line. A conventional line passes through the center of the end face. The plane of each fragment 16 is placed at an angle of 30-60° to the axis of the nozzle orifice. All the fragments 16 are bent in one direction.EFFECT: module enables to improve the efficiency of firefighting, to increase operational functionality and convenience, the range of applications by creating conditions to enhance fast operation of fire extinguishing and reliable fire extinguishing ability, regardless of its location in space.6 cl, 4 dwg Изобретение относится к противопожарной технике, а именно к модулям порошкового пожаротушения, которые являются универсальными средствами пожаротушения. Модуль порошкового пожаротушения содержит корпус 1, газогенератор 3, сопловой насадок 8, разрушаемую мембрану 9. Корпус 1 снаряжен огнетушащим порошком. Газогенератор 3 закреплен в верхней части корпуса 1 и снабжен в нижней части аэратором 4. В верхней части газогенератор 3 связан с электропусковым элементом. Сопловой насадок 8 выполнен в виде пустотелого цилиндрического сопла и размещен в горловине 7 дна корпуса с зазором. Разрушаемая мембрана 9 поджата накидной гайкой 11 к горловине 7 дна корпуса 1.
