Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe fitting connection, in particular to a PE pipe fitting flexible connection joint. Background Art

[0002] PE pipe fittings flexible connection joint is a flexible pipe fitting used to connect two PE pipe fittings. It can effectively solve the expansion and contraction deformation of the pipeline caused by temperature changes, earthquakes and other reasons during use. PE pipe fittings flexible connection joint has good flexibility and sealing performance, which can effectively reduce the vibration and noise of the pipeline system during operation. At the same time, it can also reduce the risk of leakage in the pipeline system and improve the safety and reliability of the pipeline system. This joint is widely used in pipeline connections in the fields of industry, construction, municipal administration, etc., and is a very important pipeline connection accessory.

[0003] Traditional PE pipe connectors are usually designed with fixed lengths and cannot be flexibly adjusted according to the actual spacing between water pipes. This design not only increases the difficulty of construction, but also easily leads to installation errors, and may even affect the overall performance and safety of the pipeline system. In addition, when the pipeline undergoes slight deformation due to factors such as temperature and pressure, the fixed-length connector cannot effectively absorb these deformations, thereby increasing the stress concentration and damage risk of the pipeline system.
