DEVICE FOR SPRAYING MEDIUM UNDER PRESSURE Russian patent published in 2017 - IPC B05B1/00 

FIELD: construction.

SUBSTANCE: spray nozzle for spraying polyurethane medium under pressure contains a cylindrical housing equipped on the first butt with a base with a mounting bore extending inside the above cylindrical housing, forming a cavity therein for arranging the barrel of a gun attached to a tank containing an aerosol composition. The base is made in the form of the opposite-lying lobes, the size of which is made large enough to ensure stops for the user's fingers. On the second butt of the housing a cylindrical elevation is made, the diameter of which is less than the housing diameter, and the through opening made therein on the section of the sprayed medium release from the container is connected with the through V-shaped recess open on the sides, the width of which increases in the direction of the sprayed medium release. Lamellar projections arranged one opposite the other adjoin to the lateral surfaces of the cylindrical elevation, the height of which exceeds the height of the cylindrical elevation. The second butt wall has the thickness providing that the length of the through hole made in the cylindrical projection exceeds the height of the latter. The mounting bore butt adjacent to the base is made with a circular cut. The base lobes are made with the anti-slip surface. The spray nozzle is supplied by a means of its mounting in the non-operated position.

EFFECT: improving and simplifying the process of docking a spray nozzle with a mounting gun, facilitating and accelerating the time when changing the nozzle, improving the polyurethane composition jet orientation for evenly applying to the surface to be treated and preventing the deletion of high-boiling hydrocarbon foaming agents that contribute to further polymerization and foaming of the product applied to the surface to be treated.
