摘要
本文研究的三通型先导比例减压阀,采用“系统压力直接检测、反馈”的闭环控制原理和先导级与主级的“级间动压反馈”原理,主阀采用双可变节流边的结构,先导阀采用双可变先导液阻半桥结构。该阀具有优良的“快速性”、“等压力特性”和稳定性。
For the pilot proportional pressure reducing valve of 3-way type researched,the closed-loop control theory of“directly measuring and feedback of system pressure”and the theory of“inter-stage dynamic pressure feedback between pilot andmain stages”were adopted.The structure of double variable throttle clearance was adopted to main stage while the structure of se-mi-bridge of double variable fluid resistance was adopted to pilot stage.Excellent speediness,isobaric feature and stability are pos-sessed by this valve.
