摘要
介绍了高压电-气流量伺服阀的工作原理,列出了其压力-流量特性一般方程,利用MATLAB软件针对不同开口量及不同开口形状的伺服阀的压力-流量特性进行了仿真,根据仿真结果,分析了阀芯开口形状对阀性能的影响。
The working principle of high-pressure electro-pneumatic flow servo-valve was introduced, and the general equation of pressure-flow performance was listed. By use of MATLAB, the pressure-flow performance of servo-valve for different hatch size and different ports was simulated. According to the results of simulation, the relationship of the port of spool and the performance of servovalve was analyzed.
