FIELD: fire-fighting equipment. ^ SUBSTANCE: invention relates to equipment for fire-extinguishing with application of dispersed water (DW). Fire-extinguishing element represents airtight capsule, filled with fire-extinguishing liquid, material, form and dimensions of capsule being chosen on condition of providing steam explosion of fire-extinguishing liquid during short, within several seconds, time after beginning of cover heating by fire. Capsule is supplied with hollow shank end, volume of shank end cavity forming single volume with volume of capsule, filled with fire-extinguishing liquid, shank end length being chosen on condition of possibility of its sealing. Fire-extinguishing element is made from glass tube with specified diametre and thickness of wall by heating tube area until glass softening and extending tube in area of softening with formation of shank end. In area of shank end ending work piece is cut and bottom of capsule is formed from opposite to shank end side by heating work piece, then capsule is filled thought open shank end with fire-extinguishing liquid and sealed by soldering of shank end ending. ^ EFFECT: simplification of technology of obtaining efficient fire-extinguishing element. ^ 3 cl |
