Abstract

本实用新型公开了一种超压泵配油阀,包括阀体和阀芯,阀体下部内径小于上部内径、上部与下部之间形成台阶,阀芯下部外径小于上部外径、上部与下部之间锥面过渡,阀芯的锥面与阀体的台阶内沿配合。本实用新型采用阀芯的锥面与阀体的台阶内沿配合,阀芯上端端盖压紧阀芯使阀芯的锥面与阀体紧密接触来实现阀芯与阀体的密封,密封性能好,与传统的O型圈密封相比,大大降低了超压泵配油阀的维修率,使用寿命长。

Description

一种超压泵配油阀
技术领域
本实用新型特别涉及一种六面顶压机上使用的超压泵配油阀。
背景技术
大缸径六面顶压机上使用的超压泵配油阀如图1所示,包括阀体1与安装在阀体1内部的阀芯2,阀体1上设有进油孔6和出油孔5,阀芯2上部设有端盖3,端盖3通过O型圈4与阀体密封连接,在阀芯2外壁设有O型圈4,通过O型圈4实现阀芯2与阀体1的密封。缺点是O型圈易损坏,超压泵维修率高。
实用新型内容
本实用新型的目的是提供一种密封性能好、使用寿命长的超压泵配油阀。
为达到上述目的,本实用新型采用的技术方案是:
一种超压泵配油阀,包括阀体和阀芯,阀体下部内径小于上部内径、上部与下部之间形成台阶,阀芯下部外径小于上部外径、上部与下部之间锥面过渡,阀芯的锥面与阀体的台阶内沿配合。
阀芯上端设有端盖,端盖压接于阀芯上面。
本实用新型采用阀芯的锥面与阀体的台阶内沿配合,阀芯上端端盖压紧阀芯使阀芯的锥面与阀体紧密接触来实现阀芯与阀体的密封,密封性能好,与传统的O型圈密封相比,大大降低了超压泵配油阀的维修率,使用寿命长。
附图说明
图1是现有配油阀结构示意图;
图2是本实用新型结构示意图。
具体实施方式
如图2所示,一种超压泵配油阀,包括阀体1和阀芯2,阀体1下部内径小于上部内径、上部与下部之间形成台阶8,阀芯2下部外径小于上部外径、上部与下部之间锥面过渡,阀芯2的锥面7与阀体1的台阶8内沿配合。阀芯2上端设有端盖3,端盖3压接于阀芯2上面,端盖3通过O型圈4与阀体1密封。
本实用新型工作时,油从进油孔6进入阀体1及阀芯2,通过压力顶开单向阀9,通过端盖3上的油孔经出油孔5流出;本实用新型采用阀体1的台阶8与阀芯2的锥面7相互密封,密封性能好,与传统的O型圈密封相比,大大降低了超压泵配油阀的维修率,使用寿命长。
