FIELD: fire-fighting equipment, particularly fire-extinguishers, for instance powder fire-extinguishers.
SUBSTANCE: fire-extinguisher comprises cylindrical body with head and bottom, shutoff-and-triggering device with spraying head and siphon pipe for powder distribution from cylindrical body into spraying head through shutoff-and-triggering device. Cylindrical body has mouth head including support flange secured inside cylindrical body and connected to mouth thereof by spot weld seam. The bush has cylindrical central pipe mating support flange thereof. Central pipe includes inner thread for shutoff-and-triggering device connection to cylindrical body. Sealing gasket made of elastic material is clamped between shutoff-and-triggering device and body mouth. Bottom is air-tightly secured to cylindrical body by means of welding.
EFFECT: increased body reliability, decreased labor inputs for fire-extinguisher body manufacturing and reduced body manufacturing accuracy requirement.
