Main Valve Structure Design for Water Medium Low-Pressure Large-Flow Pilot Operated Solenoid Valve
摘要
Abstract
In order to achieve the basic requirements of the large-power valve-control coupling for control valve quick response,high flow capacity,and anti-blocking ability,the main valve with a tail cone structure was designed for a water medium low-pressure large-flow pilot solenoid valve group. The influences of spring stiffness,throttle nozzles diameter,and other parameters on the dynamic and static characteristics of the valve were analyzed using the AMESim simulation software,and accordingly the optimized parameters combination of the solenoid valve group was determined. In addition,a pure water hydraulic test-bed was built to measure the response characteristics of the valve group. The results show that the normal working pressure drop of the designed solenoid valve group is about 0. 07 MPa,the opening time is 0. 3 0. 4 s,and the closing time is about 1 s. The valve group possesses a good low pressure characteristic and a fast response characteristic,which can satisfy the requirements of large-power valve-control coupling.关键词
