Technical Field

The utility model relates to the technical field of compensators, in particular to a compensator with an adjusting function.

Background

In various pipeline conveying systems, no matter conveying high-temperature fluid (such as hot water or steam conveyed by a thermodynamic pipeline) or low-temperature medium, the pipeline inevitably suffers from thermal expansion and contraction due to temperature change. For example, in a heating system, when hot water flows through a pipe, the pipe temperature increases causing it to elongate, and during cooling the pipe contracts. If the dimensional change is not reasonably compensated, huge stress can be generated inside the pipeline, and the pipeline can be bent, deformed or even broken when serious, so that the normal operation of the system is affected.

Conventional compensators, while designed to compensate for the deformation of the tubing to some extent, are generally limited in their length adjustment range. For some pipe systems with large temperature variations or installation errors outside of the conventional range, existing compensators may not fully meet the compensation requirements, resulting in pipes that are still subjected to large stresses.
