摘要
本文主要研究直动式顺序阀的启闭特性与阀的结构参数的关系。减小作用于阀芯上的液压卡紧摩接力,有利于提高阀的启闭特性。在大流量阀中,作用于主阀芯上的稳态轴向液动力对选择控制柱塞直径有显著影响。文中介绍按启闭特性要求确定控制柱塞直径和调压弹簧刚度的方法.
The paper investigates the relationship between the cracking and closing characteristics and the structural parameter of the direct sequence valve. The friction produced by hydraulic lateral forces on the spool is decreased to help improve its cracking and closing characteristics,Steadg-state axial flow force on the main spool plags an important part in selecting control position diameter of large rated flow valve.The paper presents the method to determine the control position diameter and the spring rate
