[0002] A gasket is a sealing element specifically designed for chemical tower equipment, used to provide effective sealing between trays or plates. The design of this gasket allows it to play a sealing role on both the inside and outside of the tower, thereby preventing medium leakage and maintaining normal operating conditions inside the tower. The gasket usually has good chemical stability and temperature resistance, and can adapt to the harsh environment in the chemical process.

[0003] In the prior art, when installing tray plates inside the tower, generally a small pad is welded on the thinner tray plate to locally thicken it so that it remains on a flat surface at a certain height. Then, a flat plate is fixed at the top with bolts to complete the installation of the tray plate. However, the small pad is prone to loss during storage and use, which not only increases the additional material management cost, but also affects the continuity and efficiency of the installation work. Moreover, it increases the labor intensity during welding, and at the same time increases the production process and production cost.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figure 1 - Figure 3 As shown in FIG. [FIG. number not provided], an embodiment provided by the present utility model: an equal-difference pressing gasket, including an equal-difference pressing gasket 1, an equal-difference bend 2 is arranged on the right side of the equal-difference pressing gasket 1, a reinforcement component is arranged on the top of the equal-difference bend 2, and the reinforcement component is used to play the role of a reinforcing rib. A liquid receiving tray 3 is arranged on the left side of the bottom of the equal-difference pressing gasket 1, a tray plate 4 is arranged on the right side of the bottom of the equal-difference pressing gasket 1. Thread grooves 6 are opened inside both the equal-difference pressing gasket 1 and the liquid receiving tray 3. The thickness of the liquid receiving tray 3 is 6 mm, and the thickness of the tray plate 4 is 3 mm. The equal-difference bend 2 is in a Z shape.

[0031] Specifically, the differential compression gasket 1 is the core component of the device, which is located between the liquid receiving tray 3 and the tower plate 4 and acts as a bridge. The design of the gasket takes into account the uniformity of pressure distribution. Through precise calculation and manufacturing, it ensures that the pressure can be evenly transmitted to the liquid receiving tray 3 and the tower plate 4 while being subjected to the bolt tightening force, avoiding local stress concentration and improving the overall bearing capacity. The differential bend 2 is located on the right side of the gasket and is designed in a Z shape. This shape not only increases the rigidity of the gasket, but also plays a buffering role to a certain extent. The Z-shaped differential bend 2 can produce a certain elastic deformation when subjected to force, absorb part of the impact force, reduce the direct impact on the tower plate 4 and the liquid receiving tray 5, thereby extending their service life, and avoiding the cumbersomeness of adding pads for welding when installing traditional tower plates. The reinforcement component is located at the top of the differential bend 2. Its function is similar to the reinforcing ribs in the building and can provide additional support. When the differential compression gasket 1 is tightened by bolts, the reinforcement assembly can effectively disperse the pressure, prevent the gasket from deformation or breakage under long-term stress, and ensure the stability and durability of the gasket. The liquid receiving tray 3 is located on the lower left side of the differential compression gasket 1, and its thickness is 6mm. The selection of this thickness not only ensures sufficient strength, but also avoids the inconvenience caused by excessive weight. The main function of the liquid receiving tray 3 is to receive the liquid from the upper tower plate 4, and to be tightly connected with the differential compression gasket 1 through the threaded groove 6 inside it, to ensure that the liquid can flow smoothly without leakage. The tower plate 4 is located on the lower right side of the differential compression gasket 1, and its thickness is 3mm. This thickness can not only meet the needs of the structure, but also reduce the overall weight, which is convenient for installation and maintenance. The tray plate 4 plays a role in separating liquid and gas in the distillation tower. Its close cooperation with the differential pressure gasket 1 ensures the separation effect and enhances the stability of the entire tray system. The threaded grooves 6 are respectively opened inside the differential pressure gasket 1 and the liquid receiving tray 3. Their function is to provide a fixed path for the bolts so that the bolts can be accurately screwed into and tightened to the gasket, the liquid receiving tray 3 and the tray plate 4. The design of the threaded groove 6 takes into account the size and tightening torque of the bolts, ensuring that the bolts can firmly lock the various components to prevent loosening during operation.

[0032] Reference Figure 2 and Figure 3 The reinforcement component includes a protrusion 5, both sides of which are arranged on the top of the differential compression gasket 1, the protrusion 5 is raised 3mm upward, and the protrusion 5 is in a T shape.

[0033] Specifically, the protrusion 5, as a key part of the reinforcement component, its T-shaped design not only increases the surface area of the equal-difference pressing gasket 1, but also effectively improves the contact pressure between the gasket and the tray plate 4 through the 3-mm height of the upward bulge. The protrusion 5 with a T-shaped structure is arranged on both sides of the top of the equal-difference pressing gasket 1, forming a support structure similar to a bridge. This structure provides additional support force in the vertical direction, enabling the gasket to better disperse the force when subjected to external pressure, reducing local stress concentration, improving the overall rigidity and stability of the gasket. With the reinforcement of the protrusion 5, the load-bearing capacity of the equal-difference pressing gasket 1 has been significantly improved. The gasket can not only maintain stability under normal working conditions, but also withstand greater pressure and impact in the face of extreme working conditions, ensuring the continuous and stable operation of the distillation column.

[0034] Working principle: When this device needs to be used, first place the equal-difference pressing gasket 1 on the liquid receiving tray 3 and the tray plate 4, align the bolts with the threaded grooves 6 on the liquid receiving tray 3 and the equal-difference pressing gasket 1 and slowly and firmly screw them in until the bolt heads are in close contact with the gasket surface, ensuring that each bolt can reach the specified torque value. Under the action of the equal-pressure bend 2 on the equal-difference pressing gasket 1, it is ensured that the tray plate 4 and the liquid receiving tray 3 are on a plane of the same height when installing the tray plate 4, avoiding the cumbersome process of adding pads for welding during the installation of the traditional tray plate 4, saving two processes. Under the action of the protrusion 5 on the equal-difference pressing gasket 1, the fastening force between the gasket and the tray plate 4 is effectively enhanced, thus significantly improving the overall structural strength and stability and avoiding the problem of insufficient shear force of the traditional pressing gasket, which leads to the problem that the stability of the tray plate is difficult to be fully guaranteed during long-term operation or under extreme working conditions.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
