Abstract

本实用新型涉及一种正反向都为零泄漏插装阀。它设有阀套、阀芯和弹簧。阀芯靠控制腔右端为锥面，阀芯与阀座配合安装，贴合时锥面线性密封。它和球式换向阀组成一个液压控制回路。利用此正反向零泄漏插装阀，可以保证阀门液压系统在保压时泄漏量为零，减少了系统电机油泵的启动次数，从面延长了阀门液压系统的使用寿命。

Description

正反向都为零泄漏插装阀
技术领域
本实用新型属于液压阀技术领域，涉及到一种液压系统中正反向都要求保压的零泄漏插装阀。
背景技术
目前，液控阀门普遍存在这样一种缺陷：阀门长时间打开或关闭时，液压系统总是存在着比较大的泄漏，保压效果非常差，导致液压系统频繁启动电机油泵，致使液压系统工作不可靠甚至失效。
发明内容
本实用新型的目的在于：提供一种阀芯右端为锥形并增设有阀座的正反向零泄漏插装阀，它和球式换向阀组成一个液压控制回路。
它是这样实现的：它设有阀套、阀芯和弹簧。阀芯靠控制腔右端为锥面，阀芯与阀座配合安装，贴合时锥面线性密封。
本实用新型的优点在于：利用此正反向零泄漏插装阀，可以保证阀门液压系统在保压时泄漏量为零，减少了系统电机油泵的启动次数，从面延长了阀门液压系统的使用受命。
附图说明
图1：本实用新型结构示意图。
其中：1、阀套 2、弹簧 3、阀芯 4、阀座
具体实施方式
本实用新型设有阀套1、阀芯3和弹簧2。阀芯3靠控制腔右端为锥面，阀芯3与阀座4配合安装，贴合时锥面线性密封。
