Abstract

The invention relates to a capillary inlet flow regulator. The capillary inlet flow regulator is characterized by comprising a cylindrical water outlet base, a water inlet cover, a core seat and a disk-shaped elastic membrane, wherein a round hole is arranged on the sidewall of the water outlet base, a cylindrical joint pipeline is arranged on the circumference of the round hole, the water inlet cover is arranged on the top portion of the cylindrical joint pipeline, a water inlet communicated with the cylindrical joint pipeline is arranged on the cover plate, the core seat is arranged in the cylindrical joint pipeline and comprises a round bottom plate, a cylindrical retaining wall is arranged on the top portion of the round bottom plate, a water inlet ring is formed between the periphery of the cylindrical retaining wall and the cylindrical joint pipeline, a central water outlet is arranged at the center of the round bottom plate, a plurality of fan rings protruding upwards are arranged at intervals on the circumference of the central water outlet, surfaces of the fan rings are arc-shaped, groove runners are formed between every two adjacent fan rings, a central jacking column protruding upwards is arranged in the central water outlet, detachable adjusting plates are respectively arranged at positions, corresponding to the groove runners, on the cylindrical retaining wall, and the disk-shaped elastic membrane is arranged in the cylindrical retaining wall and above the fan rings and the central jacking column.

Description

Technical field [0001] The invention relates to a flow regulator in agricultural water-saving irrigation equipment, in particular to a capillary inlet flow regulator suitable for micro-irrigation systems and having a series of flow values. Background technique [0002] In the drip irrigation system, due to friction loss and topographical changes, the pressure at each point of the branch pipe in the irrigation district is different, which makes the inlet pressure of each capillary different, resulting in different water output from each capillary, which reduces the uniformity of irrigation. The use of pressure compensation drippers can reduce the flow difference caused by the pressure deviation of the pipe network and improve the irrigation uniformity of the micro-irrigation system, but such a system is expensive. Starting from the actual situation in my country, installing a capillary-level flow regulator can improve the uniformity of the system's irrigation, and it is very econo...
