[0002] Pressure vessels are closed devices that can withstand gas or liquid pressure and maintain sufficient strength and stability. They are widely used in many industries such as chemical, energy, pharmaceutical, food processing, aerospace, etc. for storage, reaction, separation, heat exchange and other processes.

[0003] Existing pressure vessels often use multiple sets of bolts and nuts to lock the pressure vessels when tightening. Although the locking of the pressure vessels can be achieved, there are still some problems in daily use. The tightening of multiple sets of bolts requires the cooperation of multiple people, and it is also necessary to carry and use a large number of wrenches, bolts, nuts and other accessories of different sizes. This makes the installation and tightening process not simple and quick enough, and in large-scale installation projects, the work efficiency is low, which increases labor costs and installation time.

When the connecting ring moves downward, it will pull the locking column and the annular plate through the circular plate to overcome the elastic force of the spring and move downward, and finally separate the locking column from the locking groove. At this time, the tank body and the head can be separated, making it more convenient for the relevant staff to tighten and separate the pressure vessel, reducing the difficulty of operation for the relevant staff.

[0021] like Figure 2-4 As shown, the limit assembly includes an annular assembly groove 401 uniformly arranged at the upper edge of the tank body 100, the assembly groove 401 is respectively connected with the vertically adjacent limit grooves 300, and locking columns 400 are vertically slidably connected in the assembly groove 401. The lower surface of the limit plug 301 is provided with a locking groove corresponding to the locking column 400 one by one, and the upper end of the outer arc surface of the locking column 400 is provided with an annular plate 402, and the annular plate 402 is respectively located in the vertically adjacent assembly grooves 401. A spring 403 is provided between the lower end surface of the annular plate 402 and the lower wall surface of the assembly groove 401 where it is located, and the spring 403 is respectively movably sleeved on the outside of the vertically adjacent locking column 400, and the lower end of the locking column 400 is also provided with a toggle assembly.

[0022] like Figure 1-4As shown, the toggle assembly includes a connecting ring 501 slidably connected to the lower end of a group of locking columns 400 in a ring shape, and a circular plate 500 is provided at the lower end of the locking columns 400, and the circular plates 500 are all arranged in cooperation with the connecting ring 501; the toggle assembly also includes an installation groove evenly arranged in a ring shape on the top wall of the tank body 100, and the installation groove is provided with a rubidium magnet 502, and the rubidium magnet 502 is magnetically adsorbed to the connecting ring 501.

The upper sealing block 600 and the lower sealing block 601 are arranged in coordination with each other to ensure the sealing of the connection, which helps to ensure the safe storage and transportation of the medium inside the pressure vessel.

[0024] The working principle of the fastening device of a pressure vessel provided by the utility model is as follows: first, the relevant staff will flexibly connect the head 200 with the limiting groove 300 at the upper end of the tank body 100 through the limiting plug 301, and then rotate the head 200 counterclockwise. The rotation of the head 200 drives the limiting plug 301 to rotate synchronously, and the inclined surface of the upper surface of the limiting plug 301 will slide relative to the inclined surface of the upper wall of the limiting groove 300 when rotating. During the relative sliding of the inclined surfaces of the two, the head 200 will be continuously tightened downward.

When disassembly is required, the relevant staff only needs to pull down the connecting ring 501 to separate the connecting ring 501 from the rubidium magnet 502. When the connecting ring 501 moves downward, it will pull the locking column 400 and the annular plate 402 through the circular plate 500 to overcome the elastic force of the spring 403 and move downward, finally separating the locking column 400 from the locking groove. At this time, the tank body 100 and the head 200 can be separated, making it more convenient for the relevant staff to tighten and separate the pressure vessel, reducing the operating difficulty of the relevant staff.

[0025] like Figure 2-3 As shown, the cross section of the connection between the upper sealing block 600 and the lower sealing block 601 is sawtooth-shaped, which can further improve the sealing performance of the connection between the upper sealing block 600 and the lower sealing block 601.
