The currently disclosed door cover and cylinder connection structure of the quick-opening door pressure vessel adopts a meshing structure of door cover teeth on the door cover flange and clamp teeth on the cylinder flange. There is a very high stress concentration at the root angle of the clamp teeth of the cylinder flange and the root angle of the door cover teeth on the door cover flange, which makes the door cover flange and the door cover flange have a large edge stress, which is very troublesome, time-consuming and labor-intensive during the opening and closing process.

At present, some quick-opening door structures are mostly sealed by compression. Because the sealing performance and reliability of the door cover need to be guaranteed in the pressure vessel, the top cover and the base are sealed by a sealing strip. This sealing effect is poor, and after a long period of opening and closing, it is easy to cause the sealing strip to break and wear, seriously affecting the sealing performance.
