Description

管件连接方法及连接结构 技术领域
本发明涉及管件连接技术，特别是涉及一种管件连接方法及连接结构。
背景技术
传统的管道连接一般采用以下两种方式：1、先把滑紧套套在管材上，然后使用扩张器使管材端口扩大，再把接头的芯体端插入已扩大的管材端口，最后用推进工具强行把滑紧套推至接头的芯体部位，使管材受到芯体和滑紧套挤压，以达到连接和密封的效果；这种方式扩口后的管材内壁会出现较深的压痕，内孔有压痕容易导致漏水，另外所使用的扩张器是多片式的，扩内孔时，由于受力不均匀，往往会把管材扩裂；而且该方式须同时使用到扩张工具和推进工具，操作繁琐。2、先把弹性套套于管材上，然后使用多爪式扩口器使管材和弹性套扩大，管材和弹性套内径须扩至比芯体插入端大3mm左右，再把芯体插入端放进管材内部，保持此位置5-10秒的时间，待管材和弹性套收缩完成后才可松手；这种方式扩口后的管材内壁也会出现较深的压痕，有可能出现弹性套的收缩压力无法压平压痕的现象，从而导致漏水事故；另外所使用的扩张器是多片式的，扩内孔时，由于受力不均匀并且扩大量较大，往往更容易会把管材扩裂，需剪去扩裂部分重新再扩张；安装时须要等待5-10秒的时间，如操作工等待时间不足，管件的芯体插入端有可能会脱出或移位，从而出现涉漏事故；弹性套收缩速度会受到环境温度的影响，低温环境下需要的收缩时间更长些。
发明内容
基于此，本发明在于克服现有技术的缺陷，提供一种管件连接方法及连接结构，能有效避免管材破裂，且连接效率高。
一种管件连接方法，包括如下步骤：
将弹性套套设于管材的端口处，通过推进工具的夹套夹住所述管材；
将连接管体固定在推进工具的卡环上，所述连接管体的插入端的前端为导入段，所述连接管体的插入段的后端为撑开段，所述导入段的外径与所述管材内径相等，所述撑开段的外周设有前端小后端大的圆锥环；
启动推进工具，使连接管体的插入端强行插入所述管材内，所述管材和弹性套沿撑开段的圆锥环逐渐扩张，所述插入端插到位时，所述管材及弹性套回缩，使管材与所述连接管体紧密连接。
其进一步技术方案如下：
所述连接管体上设有环形凸起，所述凸起上设有环形槽，所述连接管体通过所述环形槽固定在所述推进工具上的U型的卡环上。
所述撑开段上沿其长度方向依次设有两个所述圆锥环，所述插入端通过两个所述圆锥环撑开所述管材及弹性套。
所述圆锥环的截面为三角齿状、梯形齿状或者圆弧齿状。
所述弹性套靠近管材端口的一端设有多个倒钩，所述倒钩沿弹性套的周向布置，且所述倒钩钩在所述管材的端面。
所述弹性套靠近管材端口的一端设有挡圈，所述挡圈抵接在所述管材的端面。
所述导入段的前端设有倒角。
所述连接管体为硬质塑料件或者金属件，所述弹性套为具有回缩性能的塑料套或者金属套。
所述连接管体的两端均为插入端，所述环形槽设置在两个插入端之间，将所述连接管体两端的插入端分别插入两根管材内，使两根所述管材实现连接。
一种管件连接结构，包括连接管体及弹性套，所述弹性套套设于待连接的管材上，所述连接管体的插入端的前端为导入段，所述连接管体的插入段的后端为撑开段，所述导入段的外径与所述管材内径相等，所述撑开段的外周设有前端小后端大的圆锥环，所述插入端采用所述的管件连接方法插入所述管材内。
下面对前述技术方案的优点或原理进行说明：
上述管件连接方法及连接结构，将具有一定回弹性能的弹性套预先套设在 管材上，再将连接管体的插入端插入管材内，插入端的导入段起到引导进入的作用，撑开段的圆锥环靠近导入段的一端直径小，远离导入段的一端直径大，管材及弹性套随着插入端的伸入逐渐被扩张，当插入端插到位时，管材及弹性套回缩，管材内壁与所述连接管体外壁紧密连接，弹性套的弹力压紧在所述管材外壁上，进一步提高管材与连接管体之间的密封性能。相比传统的管件连接方式，无需使用扩张工具，直接通过连接管体的插入端进行扩张，其操作一步到位，可节省大量的工作时间，而且插入端进入管材时，管材和弹性套是整周均匀扩大的，扩张量够插入端插入即可，可有效地解决扩张过大带来的管材损伤，另外撑开段的圆锥环前端小后端大形成类似倒钩结构，使已插入的管材难以拔出，进一步提高管材与连接管件之间的连接可靠性；且弹性套与管材共同扩张后回缩压紧连接管件，无需设计密封圈即可达到紧固连接和密封的效果。

参照图1、2，一种管件连接方法，包括如下步骤：
将弹性套10套设于管材20的端口处，通过推进工具的夹套01夹住所述管材20；
将连接管体30固定在推进工具的卡环02上，所述连接管体30的插入端310的前端为导入段312，所述连接管体30的插入段的后端为撑开段314，所述导入段312的外径与所述管材20内径相等，所述撑开段314的外周设有前端小后端大的圆锥环316；
启动推进工具，使连接管体30的插入端310强行插入所述管材20内，所述管材20和弹性套10沿撑开段314的圆锥环316逐渐扩张，所述插入端310插到位时，所述管材20及弹性套10回缩，使管材20与所述连接管体30紧密连接。
该方法将具有一定回弹性能的弹性套10预先套设在管材20上，再将连接管体30的插入端310插入管材20内，插入端310的导入段312起到引导进入的作用，撑开段314的圆锥环316靠近导入段312的一端直径小，远离导入段312的一端直径大，管材20及弹性套10随着插入端310的伸入逐渐被扩张，当插入端310插到位时，管材20及弹性套10回缩，管材20内壁与所述连接管体30外壁紧密连接，弹性套10的弹力压紧在所述管材20外壁上，进一步提高管材20与连接管体30之间的密封性能。相比传统的管件连接方式，无需使用扩张工具，直接通过连接管体30的插入端310进行扩张，其操作一步到位，可节省大量的工作时间，而且插入端310进入管材20时，管材20和弹性套10是整 周均匀扩大的，扩张量够插入端310插入即可，可有效地解决扩张过大带来的管材20损伤，另外撑开段314的圆锥环316前端小后端大形成类似倒钩结构，使已插入的管材20难以拔出，进一步提高管材20与连接管件之间的连接可靠性；且弹性套10与管材20共同扩张后回缩压紧连接管件，无需设计密封圈即可达到紧固连接和密封的效果。本实施例中所述的前端是指沿插入端310的插入方向，靠近前方的为前端，反之则为后端。
如图1、2所示，所述连接管体30上设有环形凸起320，所述凸起上设有环形槽322，所述连接管体30通过所述环形槽322固定在所述推进工具上的U型的卡环02上。该环形凸起320不仅设置环形槽322用于将连接管体30固定在推进工具的卡环02上，而且插入端310插入管材20后，环形凸起320起到限位作用，当管材20端面抵到环形凸起320上时，插入端310插到位，不再继续插入。为便于插入端310插入管材20，所述导入段312的前端设有倒角318。
进一步，所述撑开段314上沿其长度方向依次设有两个所述圆锥环316，所述插入端310通过两个所述圆锥环316撑开所述管材20及弹性套10。由于圆锥环316的大端直径大于管材20内径，通过两个圆锥环316共同作用撑开管材20及弹性套10，使管材20及弹性套10被撑开的长度增加，从而使两者回缩后与连接管件紧密连接的区域增多，进一步提高连接的密封性能及可靠性。
如图2所述，本实施例所述圆锥环316的截面为三角齿状，插入端310插入管材20后，可使其能进入而不能从管材20内孔拔出，根据实际需求，所述圆锥环的截面有可为梯形齿状或者圆弧齿状。
如图1、2所述，进一步所述弹性套10靠近管材20端口的一端设有多个倒钩110，所述倒钩110沿弹性套10的周向布置，且所述倒钩110钩在所述管材20的端面。设置倒钩110钩在所述管材20的端面，使弹性套10在推进过程中能稳固地固定在管材20的端口处，不至于移位。根据实际需求，也可在所述弹性套10靠近管材20端口的一端设有挡圈，所述挡圈抵接在所述管材20的端面，起到稳固弹性套10的作用。
本实施例所述连接管体30为硬质塑料件或者金属件，如铜，不锈钢，PPSU 等，能撑开所述管材20；所述弹性套10为具有回缩性能的塑料套或者金属套，如PE，301不锈钢等，能通过弹力压紧管材20在连接管体30上。
如图1、2所示，本实施例所述连接管体30的两端均为插入端310，所述环形槽322设置在两个插入端310之间，将所述连接管体30两端的插入端310分别插入两根管材20内，使两根所述管材20实现连接。即将连接管体30两端的插入端310分别插入两根不同的管材20内，实现两根管材20的密封连接。根据实际需求，所述连接管体30可以为三通管、四通管等，从而对应具有三个插入端310、四个插入端310等，实现三根管材20、四根管材20等的连接。
如图1、2所示，一种管件连接结构，包括连接管体30及弹性套10，所述弹性套10套设于待连接的管材20上，所述连接管体30的插入端310的前端为导入段312，所述连接管体30的插入段的后端为撑开段314，所述导入段312的外径与所述管材20内径相等，所述撑开段314的外周设有前端小后端大的圆锥环316，所述插入端310采用所述的管件连接方法插入所述管材20内。该管件连接结构连接紧密，密封效果好，结构简单，操作方便，且管材20在连接过程中不易被扩裂。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
