FIELD: spraying devices adapted for degassing, deactivation and disinfection of military and civil machinery, for animal and plant treatment and fire-extinguishant spraying during fire suppression. ^ SUBSTANCE: spraying device comprises body, neck, high-pressure cylinder, locking-and-triggering head and filling-and-draining pipe. Air-tight casing is installed in through stepped orifice made in inner side of locking-and-triggering head. The casing is made as sleeve to receive high pressure cylinder arranged in chamber thereof. The high pressure cylinder has tearable diaphragm. Gas channel is defined between the sealed casing and high pressure cylinder. Gas channel throat is 0.1-0.12 of sleeve cross-sectional area. Sleeve mouth is provided with collar having outer thread. Check valve is installed in sleeve bottom. Sleeve bottom may adjust high pressure cylinder in axial direction. Punching mechanism is installed in through stepped orifice and is located from outer side of locking-and-triggering head. Maximal distance between outer surfaces of filling-and-draining pipe and casing is not more than 0.9 of inner neck diameter. ^ EFFECT: increased operational reliability, enlarged storage period, possibility of device filling with aggressive, erosive compositions and solutions. ^ 2 cl, 2 dwg |
