The third seal 14 is fixedly installed at the bottom end of the upper cover 12, the moving plate 17 is arranged at the bottom end of the upper cover 12, a plurality of connecting rods 18 are fixedly installed at the bottom end of the moving plate 17, the first fixing plate 2 is fixedly installed at the top end of the inner wall of the tank body 1, a plurality of moving rods 3 are fixedly installed at the top end of the first fixing plate 2, the second fixing plate 4 is slidably installed on the outer wall of the moving rod 3, and the first seal 8 is fixedly installed at the top end of the second fixing plate 4.

[0025] It should be noted that by arranging the sealing assembly, the first seal 8 and the third seal 14 clamp the second seal 10 in the middle, and the moving plate 17 is connected to the top end of the second fixing plate 4. When the moving plate 17 moves upward, it drives the first seal 8 and the third seal 14 to press tightly against the bottom end and the top end of the second seal 10, reducing the loosening between the third seal 14 and the second seal 10, and reducing the influence of loosening on the sealing effect of the pressure vessel; by arranging the first fixing plate 2 and the moving rod 3, the second fixing plate 4 can move up and down at the top end of the first fixing plate 2, and the second fixing plate 4 is used to install the first seal 8.

[0026] In some embodiments, such as Figure 4As shown in the figure, a number of moving grooves 5 are provided at the bottom end of the second fixing plate 4. The second fixing plate 4 is slidably mounted on the outer wall of the moving rod 3 through the moving grooves 5. A number of connecting grooves 6 are provided at the top end of the second fixing plate 4. A fixing hole 7 is provided on one side of the groove wall of the connecting groove 6. A cylindrical convex block is integrally formed at the bottom end of one side of the connecting rod 18. The cylindrical convex block is engaged with the corresponding fixing hole 7.

[0027] It should be noted that when installing the upper cover 12, align the mounting block 13 on the upper cover 12 with the mounting groove 11 at the top end of the tank body 1. At this time, the bottom end of the connecting rod 18 is inserted into the connecting groove 6 on the second fixing plate 4. Rotate the upper cover 12 to move the mounting block 13 on the upper cover 12 to the other end of the mounting groove 11 to fix the upper cover 12. At this time, the connecting rod 18 also moves in the corresponding connecting groove 6, so that the cylindrical convex block at the bottom end of one side of the connecting rod 18 is inserted into the fixing hole 7. The electric push rod 16 is started to retract the output end, driving the moving plate 17 to move upward, so that the first sealing member 8 is pressed against the bottom of the second sealing member 10.

[0028] In some embodiments, as Figure 2 shown, a heat insulation frame 15 is fixedly welded to the top end of the upper cover 12. An electric push rod 16 is fixedly installed on the inner wall of the heat insulation frame 15. The output end of the electric push rod 16 extends into the interior of the tank body 1. The moving plate 17 is fixedly installed on the output end of the electric push rod 16. A third fixing plate 9 is fixedly installed at the top end of the inner wall of the tank body 1. A second sealing member 10 is fixedly installed on one side of the third fixing plate 9 by screws.

[0030] In some embodiments, as Figure 3 shown, a mounting groove 11 is provided at the top end of the tank body 1. The mounting groove 11 is L-shaped and extends to the top end of the inner wall of the tank body 1. A number of mounting blocks 13 are fixedly installed on the outer wall of the upper cover 12. The mounting blocks 13 are engaged with the corresponding mounting grooves 11.

[0031] It should be noted that the mounting blocks 13 and the mounting grooves 11 are provided to install and fix the upper cover 12 on the top of the tank body 1.

[0032] The electric push rod 16 in the present utility model is a well-known component and will not be elaborated here.

[0033] Working principle: When installing the upper cover 12, align the mounting block 13 on the upper cover 12 with the mounting groove 11 at the top of the tank body 1. At this time, the bottom end of the connecting rod 18 is inserted into the connecting groove 6 on the second fixed plate 4. Rotate the upper cover 12 so that the mounting block 13 on the upper cover 12 moves to the other end of the mounting groove 11 to fix the upper cover 12. At this time, the connecting rod 18 also moves in the corresponding connecting groove 6, so that the cylindrical convex block at the bottom end of one side of the connecting rod 18 is inserted into the fixing hole 7. The electric push rod 16 is started to retract the output end, driving the moving plate 17 to move upward, so that the first seal 8 is pressed against the bottom of the second seal 10.
