Highly anti-clogging buried pressure compensation drip irrigation irrigator

Abstract

The invention relates to a highly anti-clogging buried pressure compensation drip irrigation irrigator. The irrigator comprises an inserted pressure compensation dropper adhered to the inner wall of a PE hose through hot melting. A narrow slit water outlet is formed in the PE hose; the inserted pressure compensation dropper comprises an upper cover piece, a lower shell and an elastic film; an upper cover piece cementing surface and an assembled clamping table are arranged on the front of the upper cover piece, and the back of the upper cover piece is a flat plane; a main flow channel and an effluent buffer chamber are formed in the upper cover piece cementing surface; a holed supporting boss is formed in the effluent buffer chamber; a supporting boss and a screening positioning table as well as a recessed area and a compensation chamber water sealing ring are arranged on the back of the upper cover piece; the compensation chamber water sealing ring and the elastic film form a compensation chamber; a compensation chamber water inlet, a limiting boss and an overflow tank are arranged on the compensation chamber; a gridded filter window and a dropper screening tank are arranged on the front of the lower shell, and a filter window water inlet and a lower shell cementing surface are formed in the back of the lower shell; a suck-back prevention water sealing ring and a film mounting tank for mounting the elastic film are arranged on the filter window water inlet; and a mounting positioning table and an assembling fastener are arranged on the back of the lower shell. The irrigator disclosed by the invention is excellent in pressure compensation and anti-clogging effects.

Description

technical field [0001] The invention relates to the technical field of agricultural water-saving drip irrigation, in particular to an underground pressure-compensated drip irrigation emitter with high anti-clogging resistance. Background technique [0002] As an emerging water-saving irrigation technology, drip irrigation has developed rapidly in my country in recent years. The key equipment of the drip irrigation system is to evenly and stably drip the pressure water into the soil after dissipating energy, so as to keep the crop soil in an optimal water content state. At present, the flat emitters used in domestically produced inlaid drip irrigation emitters are basically non-pressure-compensated emitters. When the water flow pressure changes, the flow rate of the emitters will change accordingly, especially in hilly areas, which cannot be guaranteed. Uniformity and consistency of flow. However, when the emitter is used under the ground, there are often phenomena such as ...

Problems solved by technology

At present, the flat emitters used in domestically produced inlaid drip irrigation emitters are basically non-pressure-compensated emitters. When the water flow pressure changes, the flow rate of the emitters will change accordingly, especially in hilly areas, which cannot be guaranteed. Uniformity and Consistency of Flow

However, when the emitter is used under the ground, there are often phenomena such as negative pressure mud suction and root invasion, and the emitter is very prone to blockage. It is difficult for conventional drip irrigation emitters to be used underground. Therefore, the design can be buried and used. Drip irrigation emitters with compensation and good anti-clogging function are necessary
