IRRIGATION PIPELINE WITH DRIP WATER OUTLETS Russian patent published in 2020 - IPC A01G25/02 B05B1/30 

FIELD: pipelines.

SUBSTANCE: invention relates to the field of irrigation devices. Irrigation pipeline contains a pipeline having openings in the wall, a device for shutting off holes on the outer side. Irrigation pipeline (4) with holes (6, 7, 8) in wall is made of flexible plastic material of high strength, is provided with resilient elastic elements made up and embracing it as ribbed adjustment tubular branch pipes (1, 2, 3) of high strength. Inner part of walls of tubular branch pipes is equipped with tubular porous element with possibility to shut off hole in wall of irrigation pipeline. Adjusting tubular branch pipes are movable of different length from beginning to end of irrigation pipeline with possibility of fixation of each of them by means of fixed yokes (9) arranged on external surface of branch pipe, one end of which is free, and other end is fixed with removal from water outlet opening in irrigation pipe wall. Length of each elastoplastic element with tubular porous element is successively changed from the beginning of irrigation pipeline to its end at increase of injected fluid medium and maintenance of uniform flow to outlet end of branch pipe with porous element irrespective of pressure change of pumped fluid medium.

EFFECT: higher reliability.
