Abstract

为了解决拆管操作麻烦的问题，给出流体管连接装置，包括管接头和固紧安装在管接头上的塞套，有内齿卡环和推齿环装在管接头和塞套内；管道驳接时，塞套、推齿环和内齿卡环被管道穿过后，内齿卡环卡紧管壁；拆管前推齿环顺着管道插入方向推开内齿使内齿卡环松开管壁，其特征是，推齿环和塞套之间为滑动接触；在管道驳接完毕后，推齿环的顶端突出塞套外。

Description

流体管连接装置
技术领域
本实用新型涉及流体管连接装置。
背景技术
授权公告号为CN1324258C的第200310101202.7号中国专利(下称对比文件)记载了用于引导水或气体等流体流动的流体管连接装置(对比文件称之为“水或汽管连接装置”)，包括一个管接头和一个可固紧安装在管接头上的塞套，塞套被管道穿过后套在管壁外。有内齿卡环(对比文件称之为“内齿锁紧圈3”)和推齿环(对比文件称之为“启闭环2”)装在管接头和塞套内。驳接时管道穿过塞套和推齿环后向外挤开内齿穿过内齿卡环，接在管接头上；若为质地较软的塑料管，则驳接完成后内齿前端略微嵌入管壁；若为铁管或不锈钢管，则可以在管壁上开槽，让内齿前端卡入管槽内；若为铜管，则无须开槽。退出时，需要由推齿环顺着管道插入方向推开内齿后部使内齿前端松开管壁才能取出管子。
对比文件记载的推齿环外壁和塞套内壁之间采用螺纹连接，推齿环顶部开有凹位。用专用的勾头扳手勾住凹位沿管轴旋转让推齿环推开内齿卡环的内齿，管子退出后反向转动让推齿环后退使内齿回复原位。由于推齿环和塞套之间为螺纹连接，拆管时须用勾头扳手正向转动拆管，再反向转动复位，操作麻烦。
实用新型内容
本实用新型旨在解决拆管操作麻烦的问题。
本实用新型给出流体管连接装置，包括管接头和固紧安装在管接头上的塞套，有内齿卡环和推齿环装在管接头和塞套内；管道驳接时，塞套、推齿环和内齿卡环被管道穿过后，内齿卡环卡紧管壁；拆管前推齿环顺着管道插入方向推开内齿使内齿卡环松开管壁，其特征是，推齿环和塞套之间为滑动接触；在管道驳接完毕后，推齿环的顶端突出塞套外。
因为本实用新型的推齿环和塞套之间为滑动接触，所以拆管时只需轴向平移推齿环即可推开内齿，免去旋转推齿环的麻烦；取出管道后，内齿仍处于被推齿环推开后的形变状态，使用者一松开推齿环，内齿的形变弹力就把推齿环反推回原位，内齿也就得以自动复位。而对比文件因采用螺纹连接，拆除管时先用勾头板手卡住推齿环的凹位转动，才能把内齿推离管壁把管拆除；当管子退出后，反向转动勾头扳手才能让推齿环后退使内齿回复原位，不能自动复位。相比之下本发明操作更简便。本实用新型在管道驳接完毕后，推齿环的顶端突出塞套外，便于接受外来的推力将其推至推开内齿卡环。
附图说明
图1是流体管连接装置的立体分解图。
图2是流体管连接装置的装配图。
具体实施方式
图1、2给出外密封式流体管连接装置，包括塞套1、推齿环2、内齿卡环3、承托圈4、密封圈5和管接头6，内齿卡环3卡紧管壁7。塞套1放入管接头6内，用收口工具压紧或其它方式固紧，从而把推齿环2、内齿卡环3、承托圈4和密封圈5等零件包在管接头6和塞套1内。内齿卡环3放在承托圈4上，承托圈4下方是密封圈5。推齿环2和塞套1之间为滑动接触。在管道驳接状态下，推齿环2的顶端突出塞套1外，如图2所示。
如果是内密封式流体管连接装置，则内齿卡环可以直接放在管接头上，可省略承托圈。
