Description

流体管连接装置及其配套的拆管工具 技术领域 本发明涉及流体管连接装置及其配套的拆管工具。 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***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。 拆管时， 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。 该推齿环和塞套之间 采用螺纹连接结构带来两个缺陷： 其一， 拆管时须用勾头扳手卡住推齿环的凹位 正向转动拆管， 再反向转动复位， 操作麻烦； 其二， 为了让推齿环在深入塞套内 推动内齿时其顶部仍可让勾头扳手勾住， 要求在管道拆除前的长期使用过程中， 推齿环的顶部一直显著突出塞套之外， 这就使得推齿环的顶部容易被磨损、 碰伤， 导致不能顺利拆管。 发明内容 本发明旨在解决拆管操作麻烦的问题， 同时解决推齿环的顶部容易被磨损、 碰伤的问题。 本发明给出流体管连接装置， 包括管接头， 有固紧安装在管接头上的塞套把 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***方向推开内齿使 内齿卡环松开管壁； 推齿环和塞套之间为滑动接触， 其特征是， 在管道驳接状态 下， 推齿环的顶端与塞套基本平齐或缩在塞套内， 使得当内齿被推齿环推开时， 推齿环的顶端缩在塞套内。
本发明还给出与本发明的流体管连接装置配套的拆管工具， 其特征是， 包括 手柄， 手柄接有可伸入塞套与管壁之间推动推齿环的顶块。 因为本发明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， 使用者一松幵推齿环， 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。 在管道驳接状态下， 本发明流体管连接装置的推齿环的顶端与塞套基 本平齐或缩在塞套内， 推齿环的顶部不外露也就不易被磨损、 碰伤。
为了配合本发明的流体管连接装置， 本发明给出的拆管工具设有顶块， 其伸 入塞套与管壁之间把推齿环顶至推开内齿即可使内齿卡环松幵管壁， 从而取出管 道。 附图说明 图 1是外密封式流体管连接装置的立体分解图。
图 2是外密封式流体管连接装置的装配图。
图 3是第一种拆管工具的示意图。
图 4是第二种拆管工具的示意图。
图 5是第二种拆管工具的透视图。
图 6是内密封式流体管连接装置的立体分解图。 图 7是内密封式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。 塞套 4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的下方是密封圈 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的顶端与塞套 1基本平 齐， 如图 2所示。 推齿环 2的顶端也可缩在塞套 1内。 如图 3的第一种拆管工具， 设有固定手柄 10连接卡件 11， 设有活动手柄 12 连接顶块 13， 活动手柄 12和固定手柄 10在后部铰接。拆管时， 先让卡件 11卡紧 管接头 6， 然后让顶块 13对准推齿环 2的顶端伸入， 再握紧两个手柄的中后部使 活动手柄 12靠近固定手柄 10， 从而让顶块 13把推齿环 2顶至推开内齿， 使内齿 卡环 3松开管壁 7。 因为拆管工具只需单手操作， 所以可用另一只手取出管道。然 后松开拆管工具， 推齿环 2被内齿的形变弹力反向推回原位， 内齿也就得以自动 复位。 虽然该拆管工具的活动手柄 12和固定手柄 10采用简易且操作方便的铰接 方式， 两手柄之间为转动而非平动， 但因为推齿环 2的管轴向位移很短， 所以在 活动手柄 12转动靠近固定手柄 10时， 顶块 13位移的管轴向分量足以把推齿环 2 顶至推开内齿。.
拆管工具的活动手柄 12也可不与固定手柄 10连接； 拆管工具也可不设卡件 11和固定手柄 10， 改为用手直接抓住管接头 6。 但这样就难以单手操作。
拆管工具的顶块 13也可做得稍长， 长出部分作为活动手柄 12。 第二种拆管工具如图 4、 5， 卡件 11接在固定手柄 10上， 活动手柄 12铰接 固定手柄 10， 活动手柄 12位于卡件 11后方， 固定手柄 10位于顶块 13后方， 顶 块 13与活动手柄 12之间的连接方式为：
设有杠杆， 其支点 15铰接固定手柄 10， 支点 15之前接所述的顶块 13， 支点 15之后为杠杆后部 14;
活动手柄 12上接有推杆 17， 当活动手柄 12靠近杠杆后部 14时， 推杆 17推 动杠杆后部 14使顶块 13靠近卡件 11 ;
还设有连接杠杆后部 14和活动手柄 12的二连杆 18， 当活动手柄 12远离杠 杆后部 14时， 二连杆 18拉动杠杆后部 14使顶块 13远离卡件 11， 同时推杆 17 后退。 该拆管工具可以单手操作。
图 5的杠杆后部 14排布多个外齿 16， 所述的推杆 17与活动手柄 12铰接， 推杆 17可以选择顶住其中一个外齿 16以控制顶块 13的行程。 推杆 17顶住不同 的外齿 16， 顶块 13的行程也会有所不同， 起到调节行程的作用。 图 6、 7给出内密封式流体管连接装置， 包括塞套 1、 推齿环 2、 内齿卡环 3、 密封圈 5和管接头 6。 管接头 6外壁和塞套 1内壁设有相互配合的凸块 8、 9， 塞 套 1的凸块 8错开管接头 6的凸块 9装入， 然后旋转塞套 1使凸块 8、 9互相抵住 即可固紧， 也可用其它方式固紧， 从而把内齿卡环 3、推齿环 2和密封圈 5等零件 包在管接头 6和塞套 1内。 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的顶端与塞套 1基本平齐， 如图 7所示。 由于内齿卡环 3直接放在 外壳上， 故无须设承托圈 4。
