Development and experimental research on hydraulic characteristics of the pressure-regulated adjuster in the drip irrigation system

Pressure discrepancy which was produced by pressure loss of the pipe-line in the drip irrigation system was one of the main causes that lead to irrigation dis-uniformity. The paper introduced a pressure stabilization device and its structure, after testing on its hydraulic characteristics and analysis. Then the proper application boundary was presented, and several problems that appeared in the course of test were discussed.
