equipment for liquid spraying. SUBSTANCE: liquid sprayer may be used in fire-fighting equipment, for instance, as a component of sprinkler systems, in agriculture, in devices of chemical technology and heat power industry. Conical surfaces forming groove with nozzles are asymmetrical relative to transverse plane of sprayer body in point of their intersection. Angle between generator of groove upper conical surface and body transverse plane amounts from 5 to 100 dwg. Angle between generator of groove lower conical surface and body transverse plane is from 40 to 50 deg. End row of nozzles is made in the form of pair mutually perpendicular channels for liquid supply located in body longitudinal planes. Region of intersection of channels is combined with conical surface of body end part and forms outlet of each nozzle. Number of nozzles formed by paired mutually perpendicular channels ranges from 4 to 6. Conical surfaces of groove intersect channels parallel to body axis to separate them into two equal parts. EFFECT: higher uniformity and, correspondingly, intensity of liquid spraying over entire preset area. 6 cl, 1 dwg
