摘要
论文介绍通过测量阀口前后压差及间口开度，并用电子线路对压力与流量非线性关系实时校正来检测与反馈动态流量的原理。应用该原理，可使目前只能控制压力或阀口开度的单一功能电波比例阀具有控制压力、流量及阀口开度的复合功能。文中给出了这一原理的两个应用实例。
In this paper,a new principle is presented to detect and feed back dynamic volume flow through measuring pressure difference,displacement of main piston and nonlinear correcting between pressure and flow.With this new concept,the electro-hydraulic proportional valve that can control only pressure or flow has multifunction to control both pressure and flow-Two appplication examples are also presented.
