Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flexible pipe compensator especially, relate to a flexible pipe compensator with pressure monitoring joint. BACKGROUND

[0002] The pipeline compensator is also called the telescopic device or the telescopic joint, the expansion joint, and is mainly used for compensating the thermal expansion and cold shrink of the pipeline due to the temperature change. If the pipeline cannot completely freely expand or shrink when the temperature changes, thermal stress will be generated in the pipeline. In the pipeline design, this stress must be considered, otherwise it can cause the rupture of the pipeline and affect the normal production. As an important part of the pipeline engineering, the compensator plays an important role in ensuring the long-term normal operation of the pipeline.

[0003] The patent file with publication number CN220727506U discloses a bidirectional sealing sleeve type pipeline compensator. The pipeline compensator includes a pipeline compensator body and a first external thread cylinder screw-mounted to the inner walls of the front ends of the pipeline compensator body. The inner wall of the end of the first external thread cylinder away from the pipeline compensator body is fixedly installed with a size head outer pipe. The end of the size head outer pipe away from the pipeline compensator body is fixedly installed with a second external thread cylinder. The outer wall of the second external thread cylinder is screw-mounted with an external thread ring. The outer wall of the first external thread cylinder is screw-mounted with a reinforcing ring. The inner wall of the first external thread cylinder is fixedly installed with symmetrical fixed blocks. The end of each fixed block close to the center of the first external thread cylinder is fixedly installed with a second fixed ring. The front and rear ends of each fixed block are penetrated with symmetrical seventh screw grooves. The inner wall of each seventh screw groove is screw-mounted with a second screw column. The pipeline compensator can quickly install different pipelines by screw-mounting the first external thread cylinder to the inner walls of the front and rear ends of the pipeline compensator body, selecting an appropriate size of the external thread ring according to the actual inner diameter of the pipeline, screw-mounting the external thread ring to the outer wall of the second external thread cylinder, and then screw-mounting the external thread ring to the inner wall of the pipeline. The flow rate of the water flowing into the pipeline compensator can be reduced by screw-mounting the second screw columns to the inner wall of the seventh screw groove when the water flows into the first external thread cylinder. The protection of the pipeline compensator can be improved. The reinforcing ring can be screw-mounted to the outer wall of the first external thread cylinder by setting the reinforcing ring and the mounting column. Then, the mounting column is screw-mounted to the inner walls of the second and fourth screw grooves to improve the stability of the reinforcing ring after installation. SUMMARY
