Static sealing structure and pressure vessel with static sealing structure

Abstract

The invention provides a static sealing structure and a pressure vessel with the static sealing structure. The pressure vessel comprises a vessel shell, a vessel cavity formed by a cavity inside the vessel shell and a groove structure opened at the top of the vessel shell and in communication with the vessel cavity; and the diameter of the groove structure in the horizontal direction is larger than that of the vessel cavity in the horizontal direction. The static sealing structure is assembled in the groove structure and comprises a sealing end and a sealing assembly, the sealing end comprisesa head and a sealing shaft rod connected with the head, the sealing assembly comprises a sealing ring and a sealing check ring which sleeve the sealing shaft rod part in an up-and-down contact manner, so that functional partitioning is achieved, and if a workpiece in a functional area goes wrong, a new workpiece can be used for replacement; the whole pressure vessel does not need to be scrapped,and the use cost is reduced.

Description

technical field [0001] The invention relates to a static sealing structure and a pressure vessel with the static sealing structure, in particular to an ultra-high pressure static sealing structure and an ultra-high pressure pressure vessel with the structure. Background technique [0002] Industrially used containers with a pressure of more than 100MPa are called ultra-high pressure containers, which are currently widely used in petrochemical, powder metallurgy, metal forming, scientific research and other fields. [0003] According to the current Chinese pressure vessel manufacturing standards (GB 150.1-150.4-2011), its manufacture is mainly realized by welding, and the pressure vessels manufactured in this way may have problems such as weld defects, brittle fracture, and stress concentration. The resistance is not high, and the working pressure is up to 35MPa. In addition, there is another process that uses integral roll forming to manufacture pressure vessels. This proce...

AI Technical Summary

Problems solved by technology

[0005] Limited by the existing pressure vessel molding process, the pressure vessel produced is not safe, the maximum operating pressure is low, the functional division is not clear, and if there is a small problem in the vessel, the entire pressure vessel must be scrapped, unable to maintain, and the cost of use is high.
