FINELY DIVIDED LIQUID SPRAYER Russian patent published in 2018 - IPC A62C31/02 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. It is achieved by the fact that in a finely divided liquid spray, comprising a hollow cylindrical body connected to a nozzle, in which jets are made in mutually perpendicular planes, the hollow body consists of a cylindrical part with an external thread for connection to the connection of a distributing pipeline supplying liquid, a conical transition part and a cylindrical part with a large diametrical cross-section and with an internal threaded surface, but coaxially with the body, a nozzle, formed in its lower part, is formed by a cylindrical surface with an external thread interacting with the cylindrical part of the body, the cylindrical surface of the nozzle passing into the conical surface and closing the end wall perpendicular to the axis of the body, with a nozzle in its center, made with an axisymmetric nozzle and consisting of a cylindrical and conical throttle apertures connected in series, the larger diameter of the conical hole being located on the blind partition of the nozzle, the body and nozzle forming three coaxial inner cylindrical chambers, and on the nozzle, from the side opposite the liquid supply, an additional row of jets is formed which are formed, at least three pairs of mutually perpendicular vertical channels for passage of liquid and horizontal channels that, intersect on the conical side surface of the nozzle and form the outlets of each of the nozzle, wherein the pair channels are at right angles to each other in the longitudinal planes of the housing, and the conical side surface of the nozzle is formed with an apex angle of 90°.

EFFECT: technical result is the increase of fine spraying efficiency.
