Description

Technical Field

[0001] The utility model belongs to the technical field of tube sheets, in particular to a corrosion-resistant tube sheet. Background Art

[0002] The tube sheet is a round steel plate with holes slightly larger than the outer diameter of the tube. It is a round steel that fixes the tube and seals the medium in the heat exchanger. Most of the current tube sheets are fixed by bolts when in use. However, most of the tube sheets are one-piece. When the tube sheet is corroded after long-term use, it needs to be replaced as a whole, which increases unnecessary processing costs and subsequent operating procedures. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a corrosion-resistant tube sheet, which solves the problem that most tube sheets are of one-piece type and need to be replaced as a whole when the tube sheet is corroded after long-term use, thereby increasing unnecessary processing costs and subsequent operating procedures.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corrosion-resistant tube plate, comprising a plate body, a card slot is provided on the plate body, a corrosion-resistant plate is card-connected in the plate body, a limiting groove is provided on the plate body, an arc block is connected to the outside of the corrosion-resistant plate, a moving rod is provided in the arc block, a fixed plate is connected to the moving rod, the moving rod is slidably connected to the limiting block outside, and a spring is connected to the outside of the moving rod.

[0005] As a further solution of the utility model: a mounting hole is opened in the plate body, and a handle is connected to the corrosion-resistant plate.

[0006] As a further solution of the utility model: the limit block is connected to the fixed disk through a spring, and a sliding groove is provided in the arc block.

[0007] As a further solution of the utility model: a sliding block is connected under the moving rod, and the sliding block is slidably connected in the sliding groove.

[0008] As a further solution of the utility model: the limit block is clamped in the limit groove, and the arc block is clamped in the plate body.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The corrosion-resistant tube sheet is provided with a limit groove, an arc block, a moving rod, a fixed plate, a limit block and a spring. When a thrust is applied to the limit block, the spring will be deformed. The corrosion-resistant plate applies a rotational force when the handle is clamped into the plate body. When the corrosion-resistant plate is rotated to an appropriate position, the limit block is released. The reset limit block will be clamped in the limit groove. The tube sheet can realize the function of rapid assembly of the corrosion-resistant plate and the plate body through the cooperation among the limit groove, the limit block and the spring. When the corrosion-resistant plate is damaged after long-term use, it can be replaced in time, so there is no need to replace the whole body, which effectively reduces the processing cost.

[0011] 2. The corrosion-resistant tube sheet is provided with a slide groove and a slider. When the corrosion-resistant plate is connected to the plate body, the moving rod slides in the slide groove through the slider. When the corrosion-resistant plate rotates, the moving rod slides in the limit groove, thereby assisting the movement of the moving rod to a certain extent and avoiding the phenomenon that the moving rod and the plate body are stuck when the corrosion-resistant plate rotates.

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, the utility model provides a technical solution: an anti-corrosion tube sheet, comprising a plate body 1, a card slot 4 is provided on the plate body 1, a corrosion-resistant plate 2 is carded in the plate body 1, a limiting groove 6 is provided on the plate body 1, a mounting hole 3 is provided in the plate body 1, a handle 5 is connected to the corrosion-resistant plate 2, and an arc block 7 is connected to the outside of the corrosion-resistant plate 2. By setting the card slot 4, when the corrosion-resistant plate 2 is connected to the plate body 1, the arc block 7 on the surface of the corrosion-resistant plate 2 will be carded in the card slot 4, so that the card slot 4 plays a certain positioning role in the connection of the corrosion-resistant plate 2;

[0018] A moving rod 8 is provided inside the arc block 7, and a fixed disk 11 is connected to the moving rod 8. A limit block 12 is slidably connected to the outside of the moving rod 8. A spring 13 is connected to the outer surface of the moving rod 8. The limit block 12 is connected to the fixed disk 11 through the spring 13. By setting the spring 13, when the limit block 12 moves on the surface of the moving rod 8 under thrust, the limit block 12 will drive the spring 13 to deform, so that the spring 13 plays a certain supporting role in the movement of the limit block 12. When the limit block 12 loses resistance, it will be reset by the spring 13;

[0019] A sliding groove 9 is provided in the arc block 7, and a slider 10 is connected under the moving rod 8. By setting the moving rod 8, when a thrust or a pull is applied to the limit block 12, the limit block 12 will slide on the surface of the moving rod 8, so that the moving rod 8 plays a certain limiting role in the movement of the limit block 12;

[0020] The slider 10 is slidably connected in the slide groove 9, the limit block 12 is clamped in the limit groove 6, and the arc block 7 is clamped in the plate body 1. By setting the slider 10, when a thrust or a pull is applied to the moving rod 8, the slider 10 under the moving rod 8 will slide in the slide groove 9, so that the slider 10 plays a certain guiding role in the movement of the moving rod 8.

[0021] The working principle of the utility model is:

[0022] When the tube sheet is connected to the equipment, a thrust can be applied to the limit block 12, and the limit block 12 will move on the surface of the moving rod 8, and the limit block 12 will drive the spring 13 to deform when moving, and then the corrosion-resistant plate 2 is clamped into the plate body 1 through the handle 5, and the arc block 7 on the surface of the corrosion-resistant plate 2 will be clamped with the clamping groove 4, and the limit block 12 is released after applying a rotational force to the corrosion-resistant plate 2. When the corrosion-resistant plate 2 rotates to the appropriate position, the limit block 12 will be reset by the spring 13, and the reset limit block 12 will be clamped in the limit groove 6, and the corrosion-resistant plate 2 will drive the moving rod 8 to move when rotating, and the slider 10 under the moving rod 8 will slide in the slide groove 9.
