SWIRLING SPRAY Russian patent published in 2018 - IPC A62C31/02 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to spraying of fluids and can be used in fire fighting, agriculture, chemical industry, heat power engineering. This is achieved by the fact that in the nozzle comprising a hollow cylindrical body from cylindrical portion with external thread for junction to connection of distribution pipeline for liquid inlet, and internal thread for junction to dissector by means of disk and rigidly connected ring through circular plate, in which groove is made along the Archimedes spiral, having twist direction coinciding with twist direction of swirl fluid flow, which is disposed with clearance relative to body inner cylindrical surface and is fixed in its lower part by means of circular plate rigidly attached to it, by lower screw having a head, made in form of conical fairing, swirler is made in form of bushing with screw external thread with large pitch of trapezoidal profile, and internal thread, which includes threaded part of conical fairing in upper part of swirler, and cylindrical chamber serves to supply liquid, and coaxially with lower screw, to its head with conical fairing attached to spray gun in the of perforated conical bell, tip of which is facing conical fairing of lower screw.

EFFECT: technical result is increase of fine spraying efficiency.
