Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessel sealing, and specifically refers to a sealing device for a cylindrical pressure-sealed container. Background Art

[0002] Currently, the known sealing methods for cylindrical pressure-sealed containers are as follows:

[0003] One is the flange type, that is, there are flanges at both ends of the cylindrical end face. There are grooves in the flange end face for adding sealing rings, and then they are firmly connected with bolts. In this way, the sealing effect is good. However, first, this method is not conducive to disassembly; second, it is not suitable for small-diameter cylindrical pressure-sealed containers (diameter less than 200 cm); third, it is not suitable for cylindrical pressure-sealed containers with small wall thickness (wall thickness less than about 3 mm).

[0004] The second is the flip type, that is, a flip cover is directly added to the end face. This method is convenient to open, but the sealing cannot be guaranteed.

[0005] These are the two current sealing methods for cylindrical pressure-sealed containers, and their drawbacks are obvious, that is, it is impossible to take both disassembly convenience and sealing into account at the same time. Therefore, we propose a sealing device that can take into account both the advantages of convenient disassembly and sealing. Summary of the Invention

The sealing device includes a large cover and a small cover, and the large cover and the small cover are fixedly welded. It also includes a column fixedly welded together with the large cover and the small cover. A threaded sleeve is movably sleeved outside the column, and a rotary stop block is threadedly connected outside the threaded sleeve. A diamond wrench is integrally formed at the outer end of the threaded sleeve. A plurality of open counterbores are provided on the inner wall of the large outer ring, and the rotary stop block is matched and clamped with the open counterbores. A ventilation hole runs through the inside of the column, and the ventilation hole communicates with the inner cavity of the cylindrical barrel. A thread buckle is provided inside the ventilation hole near the diamond wrench, and a plug and a round gasket are threadedly connected inside the thread buckle.

[0008] Further, a small outer ring is provided at one end of the cylindrical barrel close to the bottom.

[0009] Further, the rotary stop block is triangular in shape, and the number of the open counterbores is three and matches the three corners of the rotary stop block.

[0010] Further, a T-shaped buckle sleeve is welded inside the rotary stopper, and the threaded sleeve is matched and sleeved with the T-shaped buckle sleeve.

[0011] Further, a through hole for the column to pass through is provided inside the threaded sleeve.

[0012] Further, an end face sealing ring is provided at the sealed end of the large cover and the cylindrical barrel.

[0028] The present invention will be further described in detail below with reference to the drawings.

[0029] Combined with the attached Figure 1 To the attached Figure 8 A sealing device for a cylindrical pressure-sealed container, comprising a cylindrical barrel 1, a bottom cover 2 fixedly provided at the bottom of the cylindrical barrel 1, a large outer ring 3 fixedly provided at the upper end of the cylindrical barrel 1, and the sealing device is movably provided inside the large outer ring 3. The sealing device includes a large cover 4 and a small cover 5, and the large cover 4 and the small cover 5 are fixedly welded. It also includes a column 6 fixedly welded together with the large cover 4 and the small cover 5. A threaded sleeve 7 is movably sleeved outside the column 6, and a rotating block 8 is threadedly connected outside the threaded sleeve 7. A diamond wrench 9 is integrally formed at the outer end of the threaded sleeve 7. A plurality of open recesses 10 are provided on the inner wall of the large outer ring 3, and the rotating block 8 is matched and clamped with the open recesses 10. A vent hole 11 runs through the inside of the column 6, and the vent hole 11 communicates with the inner cavity of the cylindrical barrel 1. A threaded joint 12 is provided inside the vent hole 11 near the diamond wrench 9, and a plug 13 and a round gasket 14 are threadedly connected inside the threaded joint 12.

[0030] One end of the cylindrical barrel body 1 close to the bottom is provided with a small outer ring 15.

[0031] The rotating block 8 is triangular in shape. The number of the opening sinks 10 is three and matches the three corners of the rotating block 8. A T-shaped buckle sleeve is welded inside the rotating block 8, and the threaded sleeve 7 is matched and sleeved with the T-shaped buckle sleeve. The maximum diameter of the rotating block 8 is smaller than the inner diameter of the large outer ring 3 and larger than the minimum diameter of the circle where the opening sink 10 is located.

[0032] The threaded sleeve 7 is internally provided with a through hole 16 for the column 6 to pass through.

[0033] The large cover 4 and the sealed end of the cylindrical barrel body 1 are provided with an end face sealing ring.

[0034] The inner diameter of the ventilation hole 11 is 6 mm, the depth of the threaded buckle 12 is 10 mm, and the inner diameter is 12 mm.

[0035] Specific embodiments of the present invention: Use the diamond wrench 9 on the threaded sleeve 7 to screw clockwise and counterclockwise, so that the whole sealing cover is tightly sealed and easy to open. The column 6 passes through the through hole 16 and is respectively welded and fixed to the small cover 5 and the large cover 4. The ventilation hole 11 in the column 6 is conducive to air circulation. There is an M12 threaded buckle 12 with a depth of 10 mm at the upper end of the column 6. After installing the copper plug 13 and the cowhide round pad 14, it can relieve pressure and install a pressure gauge. The sizes of the three corners of the rotating block 8 are precisely calculated, which are smaller than the inner wall of the large outer ring 3 and larger than the inner wall of the opening sink 10 of the large outer ring. In this way, it is convenient to open the whole sealing cover assembly. A T-shaped buckle sleeve with a height of 25 mm is welded inside the rotating block 8 to form a rotating block body, which is the core component of this spinning method. The column body of the threaded sleeve is an outer T-shaped buckle that cooperates with the T-shaped buckle sleeve to install the two together. The small cover 5 is welded to the large cover 4, and the whole sealing cover is complete, convenient and tidy. There is an end face sealing ring between the large cover and the cylinder body inside the sealing cover for engagement.

[0036] Working process: When the threaded sleeve 7 is screwed clockwise, the rotating block 8 rotates and presses the whole sealing cover downward, pressing the end face sealing ring against the cylinder body more tightly. Three end corners of the rotating block 8 enter the opening sink 10 of the large outer ring, and the whole process of the spinning action is completed, achieving both tight sealing and locking of the opening. On the contrary, the whole action is reversed. When the threaded sleeve 7 is screwed counterclockwise, the rotating block 8 comes out of the opening sink 10, and the whole sealing cover can be easily lifted, so that it is convenient and fast to put items into the pressure-sealed container of the cylinder body.

[0037] The above description of the present invention and its embodiments is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the spirit of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
