Connecting module for plastic-coated metal pipe
The invention belongs to the technical field of pipeline connection and particularly relates to a connecting module for a plastic-coated metal pipe. The connecting module comprises a bend arranged ina wall body, a diffusion nut used for being connected with the plastic-coated metal pipe, an installing bottom plate arranged on the wall face, and an outer connecting part arranged on the outer sideof the installing bottom plate. A first connecting end head is arranged at the end A of the bend. The diffusion nut is in thread fitting in the first connecting end head. An outer cone face is arranged at the lower end of the inner wall of the first connecting end head. An inner cone face corresponding to the outer cone face is arranged at the lower end of the diffusion nut. The outer cone face externally expands the portion, exposed to outside, of the plastic-coated metal pipe, the inner cone face carries out pressing, and connection of the plastic-coated metal pipe is achieved. According tothe connecting module, a connecting accessory can be replaced at will, moreover, sealing performance is good, and pipeline installing, overhauling and replacing are greatly facilitated. The exposed portion of the metal pipe is expanded externally through the outer cone face of the bend, and pressed through the inner cone face of the diffusion nut, and close connection of the plastic-coated metal pipe can be achieved.
本发明属于管道连接技术领域，具体涉及一种覆塑金属管的连接模块，包括设置于墙体内的弯头、用以连接覆塑金属管的扩口螺母、设置于墙面上的安装底板及设置于安装底板外侧的外接件，弯头的A端设置第一连接端头，扩口螺母螺纹配合于第一连接端头内，第一连接端头内壁下端设置外圆锥面，扩口螺母下端设置与外圆锥面对应的内圆锥面，外圆锥面将覆塑金属管下端外露的金属管外扩，并通过内圆锥面压紧，实现覆塑金属管的连接。本发明能够任意更换连接配件，而且密封性好，极大方便了管路的安装、检修及更换；本发明通过弯头的外圆锥面对外露的金属管进行外扩，并通过扩口螺母的内圆锥面压紧，能够实现覆塑金属管的紧密连接。
