Abstract

本实用新型公开了一种超压泵配油阀,包括阀体、阀体内部的单向阀以及设于单向阀上方的端盖,端盖包括压紧盖和密封盖,压紧盖压接于单向阀上,压紧盖上方设有密封盖,密封盖下部为倒锥形且锥面与阀体形成线密封。本实用新型采用密封盖的锥面与阀体密封取代了O型圈密封,密封效果好,大大降低了超压泵配油阀的维修率,使用寿命长。

Description

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内部的单向阀2,阀体1上设有进油孔6和出油孔5,单向阀2上端设有端盖3,端盖3压接于单向阀2上面,端盖3与单向阀阀芯2-1之间设有弹簧7,端盖3通过O型圈4与阀体1密封,单向阀2外壁通过O型圈4与阀体1密封。缺点是端盖O型圈易损坏,超压泵端盖漏油率高,造成超压泵维修率高。
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:
   超压泵配油阀,包括阀体、阀体内部的单向阀以及设于单向阀上方的端盖,端盖包括压紧盖和密封盖,压紧盖压接于单向阀上,压紧盖上方设有密封盖,密封盖下部为倒锥形且锥面与阀体形成线密封。
压紧盖与阀体通过丝扣连接压接于单向阀上。
阀体下部内径小于上部内径、上部与下部之间形成台阶,单向阀外壁下部外径小于上部外径、上部与下部之间锥面过渡,单向阀外壁的锥面与阀体的台阶内沿配合。
本实用新型中密封盖下部为倒锥形且锥面与阀体形成线密封,取代了O型圈密封,密封效果好;压紧盖通过丝扣连接压接于单向阀上,可以有效的保证单向阀与阀体的良好密封,单向阀外壁的锥面与阀体的台阶内沿配合实现线密封,取代O型圈密封,密封效果好;本实用新型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,超压泵配油阀,包括阀体1、阀体1内部的单向阀2以及设于单向阀2上方的端盖,端盖包括压紧盖8和密封盖9,压紧盖8与阀体1通过丝扣连接压接于单向阀2上,压紧盖8上方设有密封盖9,密封盖9下部为倒锥形且锥面10与阀体1形成线密封。阀体1下部内径小于上部内径、上部与下部之间形成台阶,单向阀2外壁下部外径小于上部外径、上部与下部之间锥面过渡,单向阀2外壁的锥面与阀体1的台阶内沿配合。
本实用新型工作时,油从进油孔6进入阀体1及单向阀2,通过压力顶开单向阀阀芯2-1,通过压紧盖8上的油孔经出油孔5流出;本实用新型采用的压紧盖8压紧单向阀2,密封盖9的锥面10与阀体1用螺丝11连接,单向阀2外壁的锥面与阀体1的台阶内沿配合实现线密封,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。
