一、前言分流集流阀是液压系统中的一种流量自动控制装置,系分流阀和集流阀的复合体。分流阀的作用是自动控制从压力源进入两个执行机构中的油液流量,使之保持同步或一定比例关系,集流阀是分流阀的逆作用装置,是用于自动控制从两个执行机构流出的油液流量,使之保持同步或一定的比例关系;而两者均与两个执行机构的负载变化无关。应用分流集流阀可以组成开环液压控制系统,实现流量自动控制以取代由液压伺服阀组成的闭环液压控制系统。由分流集流阀组成的
First, the preface diverting flow manifold valve is a flow in the hydraulic system automatic control device, Department of diverter valves and manifold valve complex. The role of the diverter valve is to automatically control the flow of oil into the two actuators from the pressure source to maintain synchronization or a certain proportion of the relationship between the diverter valve divert valve reverse effect device is used to automatically control from two execution The flow of oil out of the mechanism keeps it in synchronicity or proportionally; both are independent of the load changes of the two actuators. Application shunt manifold valve can be composed of open-loop hydraulic control system to achieve automatic flow control to replace the hydraulic servo valve composed of closed-loop hydraulic control system. By the shunt manifold composition
