NOZZLE WITH A SWIRLER OF TRAPEZOIDAL PROFILE Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for liquid spraying or atomizing.

SUBSTANCE: invention relates to equipment for spraying of fluids and can be used in fire fighting, agriculture, chemical industry and heat power engineering. In the nozzle, comprising a hollow cylindrical body with a vortex flow divider, an external thread is made at the upper part of the body to connect the distribution pipeline for supplying liquid to the fitting, and in the lower part of the casing external thread is made for connection with vortex flow divider by means of a ring-shaped retainer, to which the outer and inner perforated surfaces are attached, wherein the body has an inner cylindrical chamber for feeding fluids, in which a swirler is fitted with clearance relative to inner side surface and aligned therewith, wherein the swirler is made in the form of a sleeve 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 screen filter to the body, additional divider made in the form of a perforated spherical segment, is attached to the vertex of the cone of the outer perforated conical surface of the vortex flow divider, conical baffle is attached to the peripheral part of the perforated spherical segment of the additional divider attached to the vertex of the cone of the outer perforated conical surface of the vortex flow divider, wherein the diameters of the spherical segment and the upper diameter of the frustum cone of the baffle at the point of attachment are the same, and the cavity between the outer and inner perforated conical surfaces of the vortex flow divider is filled with a fine disperser, for example a wire of "yarn waste" type.

EFFECT: higher efficiency of liquid fine spraying.
