Nozzle with pressure compensation function, sprinkler belt and processing method of sprinkler belt

Abstract

The invention discloses a nozzle with pressure compensation function, a sprinkler irrigation belt and a processing method for the sprinkler irrigation belt. The nozzle includes an inner casing, an outer casing and an end cap, the inner casing is provided with a plurality of first water outlets on the circumferential wall, and the inner wall of the outer casing is provided with a plurality of water inlet blind holes matched with the first water outlets. There are also a plurality of first spray holes penetrating through the outer casing in the water inlet blind hole; the outer casing is sleeved on the outside of the inner casing and threaded to one end of the inner casing, and the water inlet blind hole and the corresponding first water outlet Arranged oppositely, an elastic sheath is provided between the inner sleeve and the outer sleeve, and the elastic sleeve is correspondingly sealed to the outer edge of the blind water inlet hole and the outer edge of the first water outlet. The water inlet blind hole and the first through hole of the first water outlet; the end cover is screwed on the other end of the inner casing. The water spray volume of the nozzle with pressure compensation function can be adjusted to improve the irrigation effect of the sprinkler belt.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a nozzle with a pressure compensation function, a sprinkler belt and a processing method for the sprinkler belt. Background technique [0002] At present, agricultural planting combined with irrigation technology has become the trend of green and environmentally friendly agricultural development. Agricultural irrigation technology is generally divided into three types: sprinkler irrigation, drip irrigation and infiltration irrigation, and the first two are widely used. For sprinkler irrigation technology, sprinkler irrigation belts are generally used, and sprinkler irrigation belts generally include water pipes and nozzles. The water in the water pipes is sprayed outwards through the nozzles. However, in the actual use process, the structural size of the nozzle remains unchanged, and when the water supply pressure of the water pipe remains unchanged, the water spraying volume ...

Problems solved by technology

Agricultural irrigation technology is generally divided into three types: sprinkler irrigation, drip irrigation and infiltration irrigation, and the first two are widely used. For sprinkler irrigation technology, sprinkler irrigation belts are generally used, and sprinkler irrigation belts generally include water pipes and nozzles. The water in the water pipes is sprayed outwards through the nozzles. However, in the actual use process, the structural size of the nozzle remains unchanged, and when the water supply pressure of the water pipe remains unchanged, the water spraying volume of each nozzle cannot be independently adjusted, and the water consumption in different areas cannot be adjusted in a targeted manner. leading to poor irrigation
