Description

Technical Field

[0001] The present invention relates to the technical field of pipe connectors, in particular to a pipe column connector with a telescopic compensation component. Background Art

[0002] In pipeline systems, the design of pipe string connectors becomes particularly critical, especially when dealing with thermal expansion and contraction, axial displacement, or other forms of deformation. Traditional rigid connections often fail to effectively accommodate these deformations, leading to problems such as leaks and ruptures in the pipeline system. Therefore, pipe string connectors with expansion and contraction components, known as sleeve compensators, have emerged.

[0003] A sleeve compensator primarily consists of an outer sleeve, a core tube, and connecting accessories. The outer sleeve and core tube slide relative to each other to accommodate axial deformation of the pipeline. However, ensuring stability, sealing, and ease of installation during this sliding process pose significant challenges in sleeve compensator design.

[0004] Existing sleeve compensators have several structural deficiencies. For example, the sealing ring's installation and fixing method can lead to unstable sealing performance; the core tube can easily fall out of the outer sleeve during sliding; the installation process is complex and time-consuming; and there is a lack of effective protective measures to cope with harsh working environments. These issues limit the application range and reliability of sleeve compensators. Summary of the Invention
