[0020] The connecting mechanism 1 includes a connecting flange 11, an activity groove 12 is opened in the wall of the connecting flange 11, and the outer wall of the connecting flange 11 is slidably connected to the outer wall of the support flange 31.

[0022] The wrapping mechanism 4 wraps the wrapping ring 41. An insertion groove 42 is formed at the bottom of the wrapping ring 41, a limiting groove 43 is formed on the outer wall of the wrapping ring 41, and a lower chamfer 44 is formed at the bottom of the wrapping ring 41. The outer wall of the wrapping ring 41 is slidably connected to the outer wall of the limiting ring 35 through the limiting groove 43. The inner wall of the wrapping ring 41 is slidably connected to the outer wall of the insertion block 22 through the insertion groove 42. The outer wall of the insertion block 22 is slidably connected to the outer wall of the connecting flange 11. The outer wall of the limiting plate 24 is slidably connected to the outer wall of the supporting flange 31 through the positioning groove 34. A sealing device composed of flanges is obtained by means of assembly welding. Before welding and fixing, the connecting mechanism 1, the positioning mechanism 2, the limiting mechanism 3 and the wrapping mechanism 4 are assembled. The supporting flange 31 is placed on a flat ground, and the surface of the supporting flange 31 with the positioning groove 34 contacts the ground. Then, the connecting flange 11 is sleeved outside the supporting flange 31, and the movable groove 12 on the connecting flange 11 is aligned with the sliding groove 33 on the supporting flange 31.

The wrapping ring 41 is placed on the upper surface of the connecting flange 11, and the wrapping ring 41 is inserted into the limiting ring 35 of the limiting mechanism 3 through its own limiting groove 43, thereby completing the preliminary positioning of the wrapping ring 41.

Then, the positioning mechanism 2 is inserted, and the insertion block 22 of the supporting block 21 enters the insertion groove 42 to complete the fixation of the wrapping ring 41.

[0023] Working principle:

[0024] During use, the connecting mechanism 1, the positioning mechanism 2, the limiting mechanism 3 and the wrapping mechanism 4 are assembled and welded to form the lower flange of the heat-insulating tank. The lower flange has a sealing effect, which is specifically achieved by reducing the welds at the connecting parts. When the connecting mechanism 1, the positioning mechanism 2, the limiting mechanism 3 and the wrapping mechanism 4 are spliced, each structure is welded and fixed by welding. During the welding process of the limiting ring 35 and the wrapping ring 41, due to the upper chamfer 36 and the lower chamfer 44, a weld track is left at the contact position between the limiting ring 35 and the wrapping ring 41. This track can be used as a filler weld, making it difficult for the welded part to bulge, thereby reducing the operation of grinding and leveling, avoiding the fracture of the weld during the grinding process, and thus improving the sealing performance of the lower flange. During the welding process, the setting of the positioning hole 32 and the stress hole 25 will reduce the influence caused by stress during welding. The assembled and welded lower stainless steel flange is used to improve the sealing performance of the heat-insulating tank, ensure the stability of the internal environment of the heat-insulating tank, effectively prevent gas and liquid leakage through multiple groups of welding, maintain the required temperature, pressure and other conditions inside the tank. In the high-temperature and high-pressure heat-insulating treatment, good sealing can prevent heat energy dissipation and ensure the treatment effect. At the same time, it will also ensure production safety. Gas or substances leak into the working environment. A stable internal environment helps to accurately control process parameters, thereby ensuring the stability of product quality.

[0025] A sealing device composed of flanges is obtained by assembling and welding. Before welding and fixing, the connecting mechanism 1, positioning mechanism 2, limiting mechanism 3 and wrapping mechanism 4 are assembled. The supporting flange 31 is placed on a flat ground, with the side of the supporting flange 31 having the positioning groove 34 in contact with the ground. Then, the connecting flange 11 is sleeved outside the supporting flange 31, and the movable groove 12 on the connecting flange 11 is aligned with the sliding groove 33 on the supporting flange 31. Then, the wrapping mechanism 4 is placed. The wrapping ring 41 is placed on the upper surface of the connecting flange 11, and the wrapping ring 41 will be inserted into the limiting ring 35 of the limiting mechanism 3 through its own limiting groove 43, thereby completing the preliminary positioning of the wrapping ring 41. Then, the wrapping ring 41 is rotated so that the insertion groove 42 is aligned with the sliding groove 33. Then, the positioning mechanism 2 is inserted. The insertion block 22 of the support block 21 enters the insertion groove 42 to complete the fixation of the wrapping ring 41. At the same time, the sliding block 23 at the bottom of the support block 21 slides into the sliding groove 33 and the movable groove 12, and the limiting plate 24 enters the positioning groove 34 to cooperate with the insertion block 22 to clamp the supporting flange 31 and the wrapping ring 41 to the connecting flange 11. The connecting flange 11 and the supporting flange 31 can also be secondarily fixed through the positioning holes 32, thereby completing the overall fixation. By means of assembly, the lower flange has flexibility and adaptability. The installation of the assembled flange is relatively simple, without the need for complex professional tools and a large amount of manpower. At the same time, segmented transportation is more convenient, saving installation time and cost.
