Abstract

本实用新型公开了一种排油阀,包括抽液泵,抽液泵的泵头上设有进油口和出油口,进油口及出油口分别连接有进、出油管道,进油口和抽液泵之间的管道处设有排油口,排油口处固定安装有控制阀门。本实用新型结构设计简单,操作方便,有效的放出管道中的残油,节约了成本。

Description

排油阀
技术领域
本实用新型设计一种排油阀,属于液压技术领域。
背景技术
    排油阀是一个单向阀,在弹簧压力作用下,阀上部圆锥面与阀座严密配合,其作用是在停供时,将高压油管与柱塞上端空腔隔绝,防止高压油管内的油倒流入喷油泵内。工作时,在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下,迫使柱塞作上、下往复运动,从而完成泵油任务,泵油过程可分为进油—供油—回油三个阶段。
实用新型内容
本实用新型目的在于提供一种排油阀。
本实用新型采用如下技术方案:
排油阀,包括抽液泵,其特征在于:所述的抽液泵的泵头上设有进油口和出油口,所述的进油口及出油口分别连接有进、出油管道,所述进油口和抽液泵之间的管道处设有排油口,所述排油口处固定安装有控制阀门
本实用新型的优点:
本实用新型结构设计简单,操作方便,有效的放出管道中的残油,节约了成本。
附图说明
图1   本实用新型的结构示意图。
图中1、抽液泵,2、进油口,3、出油口,4、排油口,5、阀门。
具体实施方式
实施例:如图1所示,排油阀,包括抽液泵1,抽液泵1的泵头上设有进油口2和出油口3,进油口2及出油口3分别连接有进、出油管道,进油口2和抽液泵1之间的管道处设有排油口4,排油口4处固定安装有控制阀门5。
