Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure vessel technology, specifically to a pressure vessel pipe grinding device. Background Technology
[0002] Pressure vessel nozzles are mainly used in pressure vessels, which need to withstand high pressure and ensure safe and reliable operation under long-term pressure and various working conditions to prevent safety accidents such as leakage and rupture, which could lead to serious consequences. During the design process, strict stress analysis and strength calculations must be carried out to consider the influence of various factors such as pressure, temperature, and medium on the nozzle's strength and sealing performance.
[0003] After welding the pressure vessel pipeline, the pipeline connection needs to be ground. However, when grinding manually, it is difficult to maintain a consistent level of operation due to factors such as technique and force, which can easily lead to uneven grinding of the pipeline surface. This method not only increases the labor of workers, but also results in local over-grinding or under-grinding. Therefore, we propose a pressure vessel pipeline grinding device. Utility Model Content

[0014] In this invention, during the grinding process, the operator can start the second motor, which in turn drives the rotating disk to rotate via the rotating rod. The rotating disk then moves the connecting rod, the limiting plate, and the support rod outward via the sliding groove. This allows the support rod to support the inside of the container pipe, thereby enabling the support and fixing of pipes of different sizes, improving the continuity of work and production flexibility.
