Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, and more specifically, it relates to a pressure vessel. Background Art

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels are used to store liquids or gases under pressures higher than normal atmospheric pressure. Their manufacturing and design processes pay great attention to working pressure, temperature, safety characteristics, and corrosion resistance. Operating without these considerations is likely to lead to container failures. Fields where this type of container is widely used include refineries, mining, petrochemical plants, pharmaceuticals, and nuclear reactors.

[0003] Most existing pressure vessels are welded with two support seats at the bottom. Multiple mounting holes are provided on the support seats. Two groups of studs adapted to the mounting holes are cast on the ground where the pressure vessel is installed. The multiple studs are respectively passed through the inside of the multiple mounting holes, and nuts are screwed onto the studs, and the nuts are tightened to fix the support seats and the pressure vessel to the corresponding ground.

[0004] Since the support seats are welded from iron parts and are in contact with the ground, and the humidity of the ground in some areas is relatively high, the support seats are easily corroded and damaged when they are in a humid environment for a long time. Since the support seats are welded to the pressure vessel as a whole, it is not convenient to disassemble and replace the support seats. In addition, since the studs pass through the mounting holes on the support seats, when a corroded and damaged support seat needs to be replaced, all the nuts on the two support seats need to be unscrewed, and then the pressure vessel and the two support seats need to be lifted off the ground before the corresponding support seat can be replaced. It is not convenient to disassemble and replace only one support seat, reducing the practicality of its use. Content of the Utility Model
