Description

Technical Field

[0001] The utility model relates to the technical field of vacuum insulation pipes, in particular to an antifreeze polyethylene vacuum insulation pipe. Background Art

[0002] Drainage engineering is an important system related to human life and production. It is responsible for collecting and discharging domestic sewage, industrial wastewater and natural precipitation from the roofs of buildings. In this project, drain pipes play a vital role. However, since the outdoor environment often faces severe cold challenges, thermal expansion and contraction can easily cause freezing and cracking at the joints of adjacent drainage pipes. To address this problem, we need to use a special anti-freeze device and install it on the outside of the joints of adjacent drainage pipes to effectively prevent the joints from breaking due to freezing. Unfortunately, the anti-freeze protection devices for pipe joints currently on the market still have some shortcomings: most devices cannot replace damaged parts individually after long-term use, and need to be replaced as a whole, which undoubtedly increases maintenance costs. For the above problems, there may already be technical means to solve them in the existing technology, but this case wants to provide an alternative or replacement technical solution.
