Main Valve Structure Design for Water Medium Low-Pressure Large-Flow Pilot Operated Solenoid Valve

摘要

摘要: 为了实现大功率阀控偶合器对控制阀响应速度快、通流能力大且具有抗阻塞能力的基本特性要求，设计了主阀带有尾锥结构的水介质低压大流量先导式电磁阀组.应用AMESim仿真软件分析了弹簧刚度、节流孔直径等参数对阀的动、静态特性的影响，确定了电磁阀组的优化参数组合，并搭建了纯水液压试验平台，对电磁阀组的响应特性进行测试.研究结果表明：所研制的电磁阀组正常工作压降约为0.07 MPa，开启时间0.3~0.4 s，关闭时间1 s左右，有较好的低压特性和快速响应特性，能够满足大功率阀控偶合器工作需要.

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.
