a compensator

Abstract

The invention relates to the field of compensators, specifically a compensator, including an axial displacement compensation mechanism and a lateral displacement compensation mechanism. A lateral displacement compensation mechanism is arranged directly above the axial displacement compensation mechanism. , an outer sleeve and an inner sleeve, the present invention sets an axial displacement compensation mechanism, utilizes the cooperation between a plurality of piston bolt rods and the piston tube, and the telescopic sliding between the outer sleeve and the inner sleeve, which can It is suitable for the displacement change between the pipes and realizes the adjustment of the axial distance. By setting the lateral displacement compensation mechanism and setting the silicone rubber tube and the pipe cover between the inner and outer cylinders, it can prevent the large gap between the outer cylinder and the inner cylinder. The axial movement of the pipe can avoid the damage of the inner cylinder and the outer cylinder caused by the expansion of the pipeline, and at the same time, it can reduce the mutual friction and affect the sealing effect, thereby greatly increasing the service life of the lateral displacement compensation mechanism and improving the utilization rate.

Description

technical field [0001] The invention relates to the field of compensators, in particular to a compensator. Background technique [0002] The compensator is a connecting device connecting two pipelines, which can compensate the axial, transverse and angular thermal deformation of the absorption pipe, facilitate the installation and disassembly of the Famen pipeline, reduce the impact of equipment vibration on the pipeline, and absorb the shock caused by earthquakes and ground subsidence. The amount of deformation of the pipe. [0003] Existing gas pipelines mostly use axial compensators during installation. Because the thermal expansion and contraction of the pipelines caused by temperature changes are compensated, the deformation caused by thermal stress in the pipelines is eliminated. Gas pipelines are mostly installed underground. Geological changes and vibrations can easily cause the gas pipeline to rupture due to the horizontal direction; however, if two pipelines are c...

Problems solved by technology

[0003] Existing gas pipelines mostly use axial compensators during installation. Because the thermal expansion and contraction of the pipelines caused by temperature changes are compensated, the deformation caused by thermal stress in the pipelines is eliminated. Gas pipelines are mostly installed underground. Geological changes and vibrations can easily cause the gas pipeline to rupture due to the horizontal direction; however, if two pipelines are connected, if there are deformations in different directions, different types of compensators need to be installed at the same time, which not only consumes materials, but also increases the installation volume, which is not easy It is difficult to disassemble and assemble. In addition, the traditional axial displacement compensator is not stable enough to adjust the axial distance. Due to the long-term torsion of the lateral displacement compensator, the friction between the inner and outer cylinders is relatively large, which easily reduces the sealing performance and affects the service life.
