具体实施方式
第一实施例
如图1-5所示，本实施例公开了一种便于泄漏检测的双层管件接头组件，用于连接由内层管15和外层管16组成的双层管，包括主体管1，主体管1采用PE材质，主体管1为直管，主体管1设置有中心孔17，中心孔17包括位于主体管1两端的、并与外层管16配合的端头孔18和位于端头孔19之间的、与内层管15配合的中孔，端头孔18的内径大于中孔的内径，使得两端的端头孔18与中孔19之间分别形成台阶面2。
主体管1中部的侧壁内设置有PE材质的环形支架3，环形支架3的外壁上设置有介质导流管卡槽4，介质导流管卡槽4内卡置有介质导流管5，环形支架3以及卡置在环形支架3上的介质导流管5通过注塑工艺设置在主体管1内，环形支架3的内壁设置有一圈环形凸台6，环形凸台6向内凸出主体管1形成限位台阶7。
主介质导流管5的两端沿主体管1内两侧的台阶面2伸出，台阶面2上分别均布有多个凸台8，凸台8的高度略大于介质导流管5由两端台阶2的台阶面向外伸出的长度。
主体管1的侧壁内设置有电熔电阻丝9，主体管两端设置有电极10，电极10与电熔电阻丝9电连接，主体管1两侧的外壁上分别设置有圆形孔11，圆形孔11内设置有与主体管1为一体式结构的挤出件12。
本发明使用时的具体连接过程为：外层管16分别套装在主体管1的端头孔18中、并且内端分别顶压在对应凸台8上，内层管15套装在主体管1的中孔19内、并且内端分别通过限位台阶7限位，外层管16与内层管15之间留有空隙，外层管16与内层管15之间的空隙通过介质导流管5相互连通，使得双层管件之间360°贯通，任何点的介质泄漏都可以被迅速检测，保证介质(特别是可燃介质)的安全输送。
再将两端的电极10连接电源，电熔电阻丝9发热，分别将内层管15、外层管16与主体管1熔接为一体，当挤出件12在主管体1受热膨胀的压力下，被挤出圆形孔11，即断开电源，电熔完成。
在本实施例中，台阶面2上凸台8的高度略大于介质导流管5由对应侧台阶面2向外伸出的长度，保证外层管16与内层管15之间的空隙通过绝缘隔热管14相互连通。
在本实施例中，介质导流管5由金属内管13以及套装在金属内管13外的绝缘隔热管14组成，绝缘隔热管14采用聚四氟乙烯制成，通过绝缘隔热管14隔断电熔时的热量，避免热量传递至金属内管13而烫坏主体管1。
第二实施例
如图6-8所示，第二实施例与第一实施例的结构和原理大体结构，不同点在于：主体管20为弯管，弯管设置有中心孔21，中心孔21包括位于主体管20两端的端头孔22和位于端头孔22之间的中孔23，端头孔22的内径大于中孔23的内径，使得两端的端头孔22与中孔23之间分别形成台阶面24，台阶面24上分别设置有凸台28，中孔23的两端口内分别设置有限位台阶31。
主体管20的折弯部的侧壁内设置有与折弯部配合的弯管支架25，弯管支架25采用PE材质，弯管支架25的外壁上设置有介质导流管卡槽26，介质导流管卡槽26内卡置有介质导流管27，弯管支架25以及卡置在弯管支架25上的介质导流管27通过注塑工艺设置在主体管20内，介质导流管27的两端沿主体管1内两侧的台阶面24伸出。
本发明连接时：外层管29分别套装在主体管20的端头孔22内、并且内端分别顶压在对应凸台28上，内层管30套装在中孔23的两端口内、并且通过限位台阶31限位，再通过电熔焊将外层管29、内层管30与主体管20密封连接为一体，具体原理与第一实施例相同。
