SPRINKLING NOZZLE Russian patent published in 2008 - IPC B05B1/18 

FIELD: technological processes; sprinkling.

SUBSTANCE: invention is related to technology of irrigation with fine-dispersive and drip sprinkling. Sprinkling nozzle consists of casing, which is fixed in water supply pipeline, with deflectors that are fixed on its side surface. Deflectors are made in the form of concave bowls, which are turned to the side of water supply pipeline and which are installed on the external surface in steps. In front of every deflector along the casing circle perimeter inclined openings are made in the wall. Lower elements of openings are conjugated with bottom surface of deflector. Angle of incline of openings upper row to the casing axis is 25÷30°, and of openings lower row is 20÷25°. Behind the upper row of openings inside the casing, flow divider is installed, the external and internal surfaces of which are truncated cones. External surface of divider is conjugated with lower elements of openings, internal surface of flow divider is made as confusor. Behind the lower row of inclined openings there is a conical splitter, the external surface of which is conjugated with lower elements of openings lower row.

EFFECT: improves reliability of operation and simplifies design of sprinkling nozzle.
