FIRE-EXTINGUISHING APPARATUS AND SYSTEM Russian patent published in 1998 - IPC

FIELD: fire-extinguishing equipment. SUBSTANCE: fire-extinguishing apparatus has at least one spraying head with outward oriented nozzles. Nozzle spacing, spraying direction, initial size of drops and sprayed liquid pressure are related so as to intensify joint sprayed liquid flow. Fire-extinguishing system used, for instance, in vessel machinery section or like premises has liquid pump, main pipeline, which may be brought to fire-extinguishing zone and fire-extinguishing apparatus. Liquid pump is constructed so that hydraulic accumulators may be charged, when system is in non-operative position. Main pipeline may be cut off upon recharging of accumulators. Hydraulic accumulators are adapted for supplying liquid to fire-extinguishing zone. EFFECT: increased efficiency in fire-extinguishing by intensified and concentrated joint flow of sprayed fire-extinguishing substance. 20 cl
