FIELD: fire prevention facilities.SUBSTANCE: invention relates to fire equipment, in particular, to a device of gas fire extinguishing. The device of gas fire extinguishing comprises replaceable gas generation elements. The elements are made in separate bodies, each comprising a gas generating charge, an ignition composition, a cooler filter. The gas generating element is equipped with an electric trigger element. Holes on the side surface of the tight body are closed with opening elements. The central channel of each charge is arranged as dead. In the end of the additional cylindrical and conical body at the side of gas displacement there is a separator filter installed with a gap. The filter separator is made from a corrugate filtering paper. The paper is rolled into a cylinder, side surfaces of which are equipped with metal nets, and ends are equipped with an upper dead and lower with a central hole, metal covers. The net is glued with a gas permeable cloth. The cooler filter is made of pelletised or granulated sodium bicarbonate and fills the entire space of each gas generator. Gas generators are arranged with a gap in the body of the device, which is equipped with a cover and a single source of supply for simultaneous start-up of all gas generators. In the bottom part of the device body there are holes.EFFECT: device provides for acceleration and simplification of serviceability recovery after actuation, has balance of its body temperature and gas temperature at the outlet of the device with gas composition, variability of the quantity of gas generating elements.4 cl, 5 dwg |
