Problems solved by technology

[0006] Generally speaking, the flow passage structure of the flow regulator is one of the main factors affecting its performance. The existing capillary inlet flow regulator flow passage structure in the market has defects, the flow regulation performance is not ideal, and the starting pressure difference is shown. Disadvantages such as too large, insufficient flow stability, and narrow suitable working pressure range; cylindrical silicone tubes or other complex elastic regulators require high processing accuracy, and manufacturing deviations are not easy to control, resulting in unstable performance of the flow regulator , low assembly efficiency

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 the friction loss and the change of terrain, the pressure of each point of the branch pipe in the irrigation area is different, which makes the working pressure of each capillary inlet different, resulting in the different water output of each capillary, which reduces the uniformity of irrigation. The pressure compensation dripper 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. Proceeding from the actual situation in our country, installing a capillary flow regulator can improve the irrigation uniformity of the system and is very economi...
