Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on those shown in fig. 1, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The utility model discloses a novel PVC pipeline, below combine the attached drawing, further describe utility model's structure principle and theory of operation.

As shown in fig. 1 and 2, the novel PVC pipe comprises a pipe body 1, wherein the pipe body 1 comprises a first PVC layer 11, a steel wire terylene composite layer 12 and a second PVC layer 13 which are sequentially compounded from outside to inside, preferably, the steel wire terylene composite layer 12 is in a net structure, so as to solve the problem that the thermal expansion coefficient curve of a single steel wire and a PVC material is not overlapped, and the PVC material is easily peeled off by the steel wire at a low temperature, the outer surface of the pipe body 1 is provided with a plurality of axial raised lines 14, the raised lines 14 can help the pipe body 1 to be protected from impact when being extruded by an external force, the pipe body 1 is protected, meanwhile, one end of the pipe body 1 is provided with an external thread 15, the other end of the pipe body is provided with an internal thread 16 matched with the external thread 15, so that a plurality of PVC pipes are connected through the internal thread 16 and the external thread 15, the connection is more stable and reliable.
