INJECTOR WITH TRAPEZOIDAL PROFILE SWIRLER Russian patent published in 2018 - IPC A62C31/02 

FIELD: technological processes.

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 with a vortex flow divider, in the upper part of the body, an external thread is made for connection to the coupling point of the distribution pipeline for the supply of liquid, and in the lower part of the body an external thread is made for connecting with a conical dissector of the vortex flow by means of a ring-shaped casing to which the outer and inner perforated surfaces are attached, wherein in the body there is an inner cylindrical chamber that serves to supply liquid and in which a swirler is mounted coaxially with a clearance with respect to its inner lateral surface, wherein the swirler is made in the form of a hub with a screw external thread with a large pitch of the trapezoidal profile and fixed by means of an internal thread on the rod, which is fixed in its upper part by means of a strainer to the body.

EFFECT: high efficiency of liquid atomizing.
