Abstract

本发明涉及石油天然气管道设备领域，具体是一种单向液压缓冲器；特征是：包括缸体、缸盖和活塞，活塞设置在缸体中并可上下移动，在缸体中充满油液，缸体端部设置缸盖，在活塞上分别设有单向止回阀结构和节流孔结构，在缸盖与缸体之间、缸体与活塞之间设有密封环；其中，活塞向下运动时，单向止回阀关闭，整个装置实现缓冲作用，缓冲的速度通过调节节流孔来实现，当活塞向上运动，单向止回阀打开，此时整个装置无缓冲作用。通过此装置可实现在向下运动有缓冲功能，从而避免或减缓了产品发生碰撞的程度。

Description

一种单向液压缓冲器
技术领域
本发明涉及石油天然气管道设备领域，具体是一种单向液压缓冲器。
背景技术
目前，气压驱动阀在石油管道的应用中经常会出现闸板拉伤或卡死等情况，从而使得整个气压驱动法的使用寿命明显减短，并且受损后整个气压驱动阀的振动噪声很大。
发明内容
本发明的目的在于克服上述缺陷，提供一种可减缓闸板拉伤，延长使用阀门使用寿命及减少阀门振动的缓冲装置。
为了达到上述目的，本发明是这样实现的：
一种单向液压缓冲器；包括缸体、缸盖和活塞，活塞设置在缸体中并可上下移动，在缸体中充满油液，缸体端部设置缸盖，在活塞上分别设有单向止回阀结构和节流孔结构，在缸盖与缸体之间、缸体与活塞之间设有密封环；其中，活塞向下运动时，单向止回阀关闭，整个装置实现缓冲作用，缓冲的速度通过调节节流孔来实现，当活塞向上运动，单向止回阀打开，此时整个装置无缓冲作用。
将本装置接入管路总，当本装置中的活塞在向下运动时可产生缓冲功能，从而避免或减缓了阀门发生碰撞的程度。
附图说明
图1为本装置的剖视图。
具体实施方式
以下通过具体实施例进一步说明本发明。
如图1所示，一种单向液压缓冲器；其特征是：包括缸体1、缸盖2和活塞3，活塞3设置在缸体1中并可上下移动，在缸体1中充满油液4，缸体1端部设置缸盖2，在活塞3上分别设有单向止回阀结构5和节流孔结构6，在缸盖2与缸体1之间、缸体1与活3塞之间设有密封环7；其中，活塞向下运动时，单向止回阀关闭，整个装置实现缓冲作用，缓冲的速度通过调节节流孔来实现，当活塞向上运动，单向止回阀打开，此时整个装置无缓冲作用
将本装置接入管路总，当本装置中的活塞在向下运动时可产生缓冲功能，从而避免或减缓了阀门发生碰撞的程度。
