CENTRIFUGAL VORTEX NOZZLE Russian patent published in 2018 - IPC A62C31/02 

FIELD: fire safety.

SUBSTANCE: invention relates to fluids spraying equipment and can be used in firefighting equipment, agriculture, in devices of chemical technology and in heat power engineering. This is achieved by fact, that in the centrifugal vortex nozzle containing housing, union nut, insert with tangential convergent channels, twisting chamber, nozzle and a disc adjacent to the insert end face from the tangential channels, wherein the insert and disk are made out of metal-ceramics, input edges of the tangential channels are rounded, in the end face of the union nut, axisymmetric to the housing, there is a central hole consisting of cylindrical and taper parts, and the insert has at least three tangential channels, located in plane perpendicular to housing axis, as well as the twisting chamber connected to tangential channels, throttle hole located coaxially to the housing at the bottom of the insert, and a disc adjacent to the insert end from the tangential channels side perpendicular to the axis of the housing, and to the end face of the union nut, axisymmetric to the housing, fluid flow divider is attached, wherein the divider is made in the form of a perforated conical shell with a base, fixed by screws on the end face of the union nut, wherein the shell conical surface vertex is directed away from the liquid flow swirler, and in the lower part of the divider a spherical perforated segment is fixed so that the shell conical surface vertex coincides with the center of the spherical surface of the perforated segment.

EFFECT: technical result is high efficiency of spraying due to reduced hydraulic resistance of the injector while maintaining flow characteristics, providing homogeneous mixing with inflowing medium.
