电控单向阀的设计与分析

Design and analysis of an electro hydraulic check valve

阐述了电控单向阀的工作原理和开启条件，对该阀的开启、复位特性进行了仿真分析和试验研究，并通过试验表明安装该阀可有效防止液压电梯的沉降。

This paper formulates the working principle and openning condition of an electrohydraulic check valve, and analyzes its dynamic openning and closing properties through simulation and experiments. It is proved in application that this valve can be used for preventing the subsidence of a hydraulic elevator effectively.
