MULTIPHASE FLUID FEEDING AND DISPENSING NOZZLE Russian patent published in 2009 - IPC A62C31/02 B05B3/14 

FIELD: fire safety.

SUBSTANCE: invention refers to fire-control engineering and can be used for fire-fighting, spraying, cooling, airing in multiphase fluid feeders. The result is ensured as follows. Multiphase fluid feeding and dispensing nozzle contains the housing with the internal flow passage mounted on the supply tube. According to the solution the nozzle housing is lengthwise cut along the jet end thus forming the periodic element crowned at the ends. The nozzle housing is fixed to the tube through the damping tubular and enveloped on the external surface of the jet end. Herewith lengths of the lengthwise cuts on the jet end are different. The periodic elements are crowned at the ends thus observing aerodynamically active form. Damping tubular element represents a rolling diaphragm, while the envelope is fixed with a lock-nut.

EFFECT: ensured result is improved dispersion of supplied multiphase fluid, lower hydraulic resistance and structural complexity of the nozzle, possibility to obtain high consumption indicators in dispersing multiphase fluids, improved reliability and technological effectiveness.
