Description

一种球型阀芯液动阀
技术领域
本发明涉及一种液压阀，特别涉及一种球型阀芯液动阀。
背景技术
治漏是液压行业一直都在努力研究、施用各种办法做到及至的方向和目标，泄漏使液压系统功率消耗并产生热量，从而导致效率下降、介质老化、污染环境使资源浪费。现有的换向阀主阀芯结构多为柱型，在阀位变换中，密封件不断摩擦，易造成磨损或位移，影响阀机能和密封效果。
发明内容
针对现有技术的不足，本发明提供一种球型阀芯液动阀。
本发明采用的技术方案是：一种球型阀芯液动阀，为二位三通液动阀，包括阀体和端盖，所述阀体内设置阀芯，所述阀芯两端分别设置先导活塞和复位弹簧，所述阀芯为球型，所述阀芯两边设置第一密封油口和第二密封油口，所述第一密封油口连接P口，所述第二密封油口连接T口，所述阀芯所在油腔连接T口。
本发明球型阀芯，相比柱型阀芯大大减少了密封件的摩擦，有效防止油液内泄，保证通路畅通，封闭路严密防泄，大大延长使用寿命。本发明结构简单，响应快速，即可单独使用，也可作为其他阀的先导阀使用，应用范围广泛。
附图说明
图1为本发明结构示意图；
图2为本发明机能图；
图中：1-阀体，2-复位弹簧，3-球型阀芯，4-先导活塞，5-端盖，6-先导接口，7-第一密封油口，8-第二密封油口，9-柱型阀芯，10-第一油腔，11-第二油腔，12-第三油腔。
具体实施方式
如图1所示，阀体1与端盖5通过螺钉固定，阀体1底部依次开P、A、T口，其中，P口连接第一油腔10，A口连接第二油腔11，T口连接第三油腔12，第一油腔10内设置复位弹簧2，第二油腔内设置球型阀芯3，第三油腔12内设置柱型阀芯9，柱型阀芯9上设置先导活塞4，第一、第二油腔连接处为第一密封油口7，第二、第三油腔连接处为第二密封油口8，第一、第二密封油口设置密封结构。
使用时，当先导接口6无控制油连接时，球型阀芯3在复位弹簧2及P口压力油作用下紧贴第二密封油口8，此时P、A口连通；当先导接口6连接控制油时，柱型阀芯9在先导油作用下左移，通过先导活塞4推动球型阀芯3紧贴第一密封油口7，此时T、A口连通。因此，本使用新型为二位三通液动阀，其机能机构如图2所示。
