Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, and particularly relates to an anti-freezing and anti-cracking polyethylene pipeline. Background Technique

[0002] Polyethylene pipes are generally made of synthetic resin, that is, polyester, as raw materials, and stabilizers, lubricants, plasticizers, etc. are added, and are processed by extrusion in a pipe-making machine by the method of "plastic molding". It is mainly used as the water supply pipe for the tap water supply system of housing construction, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and conduits for wire installation. When the existing polyethylene pipes are in cold weather, the water in the pipes is prone to get cold and then freeze. The force between water molecules becomes weak, the molecular spacing is larger, and the volume will become larger. However, the polyethylene pipes have poor ductility, and the frozen water will crack the pipes, affecting the service life of the pipes. Content of the Utility Model

[0003] The purpose of this application is to provide an anti-freezing and anti-cracking polyethylene pipeline to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, this application provides the following technical solution: An anti-freezing and anti-cracking polyethylene pipeline includes an inner polyethylene pipe and an outer polyethylene pipe. The outer polyethylene pipe is sleeved outside the inner polyethylene pipe. A number of first strip-shaped protrusions are fixedly installed on the inner wall of the outer polyethylene pipe at uniform intervals. A slot is opened on the first strip-shaped protrusion along its length direction. A number of second strip-shaped protrusions are fixedly installed on the outer wall of the inner polyethylene pipe at uniform intervals. The second strip-shaped protrusions are inserted into the slots one by one. A vacuum insulation cavity is enclosed between the inner polyethylene pipe and the outer polyethylene pipe. A waterproof layer and a thermal insulation layer are fixedly installed on the inner wall of the outer polyethylene pipe, and are arranged in sequence from outside to inside.
