AI Technical Summary

Technical Problem

During long-term use, the temperature of the heating medium in heat transmission pipelines varies greatly, resulting in significant temperature fluctuations inside the pipelines. This causes thermal deformation and elongation, leading to loosening or cracking at pipeline connections and affecting normal operation.

Method used

Compensation devices, including grooved rings and round pipes, are installed at both ends of the pipe body. They are fixed by welding and use components such as rotating rods, springs and rubber rings to realize the relative displacement between the pipe body and the grooved ring, eliminate the connection deflection stress caused by thermal deformation, and enhance sealing and stability.

Benefits of technology

It effectively avoids deflection stress caused by thermal deformation at pipe joints, improves the service life and sealing performance of pipes, and reduces the risk of loosening and cracking at pipe joints.

Abstract

This utility model provides a thermoelectric heat transfer pipeline, relating to the field of heat transfer pipeline technology. The utility model includes a pipe body with a compensation device at one end. The compensation device includes a grooved ring and a circular pipe. A circular ring is fixedly connected to one end of the circular pipe, and a flange is fixedly connected to the end of the circular pipe away from the circular ring. A conical ring and a rubber ring are fixedly connected to one side of the inner wall of the grooved ring. This utility model, by setting up the compensation device and welding grooved rings to both ends of the pipe body, installs the grooved ring and the circular pipe at both ends of the pipe body. The pipe body is connected by the flange at one end of the circular pipe. When the pipe body undergoes thermal deformation and thermal elongation, the pipe body will cause relative displacement between the grooved ring and the circular pipe, changing their relative angle. This eliminates the deflection stress at the connection point caused by pipe deformation, minimizing the problem of pipe deformation during use and extending the service life of the pipe body.
