JET WITH HEMISPHERICAL DIVIDER Russian patent published in 2014 - IPC A62C31/00 

FIELD: fire safety.

SUBSTANCE: jet with a hemispherical divider comprising a hollow housing with a nozzle and a central core. The housing is made with a channel for supplying the liquid and has a coaxial sleeve rigidly connected to the housing, with a nozzle fixed to its lower part, made in the form of a two-stage cylindrical sleeve. The upper cylindrical stage of the sleeve is connected by a threaded connection with a central core, mounted with an annular gap with respect to the inner surface of the cylindrical sleeve. According to the invention, the divider consists of a cylindrical part with a spherical segment fixed via a pin, coaxially with it, in the lower part, which has the throttle holes, which axes are located along radii of the spherical surface forming the spherical segment or parallel to the axis of the jet housing. The annular gap is connected to at least three radial channels made in the two-stage sleeve, connecting it to the annular cavity formed by the inner surface of the sleeve and the outer surface of the upper cylindrical stage, at that the annular cavity is connected with the housing channel for supplying the liquid, on the side surface of the cylindrical part of the central core, in its lower part connected to the spherical segment, at least two rows of cylindrical throttle holes are made, with axes lying in planes perpendicular to the core axis and in each row at least three holes are made. At that the axes of the throttle holes of one row are displaced relative to the axes of the throttle holes of the other row by the angle lying in the range of 15°÷60°.

EFFECT: device enables to improve the efficiency of fine atomisation of liquid.
