Description

Technical Field

[0001] This utility model relates to the field of rubber ring technology, specifically a flange rubber ring with a centrally located force-bearing structure. Background Technology

[0002] Flange rubber rings are annular seals made of elastic materials or metal composite materials. They are used to fill the microscopic gaps at the flange connection surface, prevent media leakage, and adapt to mechanical vibration and temperature changes. They fill the flange gaps through elastic deformation, preventing the leakage of media such as oil, water, and gas, effectively ensuring system safety. In addition, they can absorb equipment vibration and impact forces, reduce the mechanical stress of flange bolts, and extend the service life of equipment.

[0003] In recent years, with the rapid development of the environmental protection industry, large-scale filtration equipment has been used more and more widely in industry. In the existing large-scale filter cylinder products, the original flange assembly process cannot meet the high precision requirements of the new products. Especially in the process of large-scale filter cylinders with double-sided irregular designs, the original flat design of the rubber gasket cannot adapt to the assembly requirements of double-sided irregular flanges, which easily leads to poor fit between the rubber gasket and the flange, reduced sealing performance, and the use of flat rubber rings in the assembly process of double-sided irregular flanges will cause uneven stress on the double-sided irregular flanges, and even serious tilting of the double-sided irregular flanges after assembly, resulting in a decrease in assembly accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a flange rubber ring with a centrally located force-bearing structure to solve the problem mentioned in the background art that the use of a flat rubber ring during the assembly of double-sided irregular flanges leads to uneven force on the double-sided irregular flanges, resulting in a decrease in assembly accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange rubber ring with a centrally located force-bearing structure, comprising a flange rubber ring body, an outer ring reinforcing rib, and an inner ring reinforcing rib.

[0006] The flange rubber ring body has symmetrical protrusions and grooves on its upper side, and through holes are equidistantly opened inside the flange rubber ring body. The flange rubber ring body has an outer ring reinforcing rib and an inner ring reinforcing rib connected inside, and an opening is opened in the middle of the flange rubber ring body.

[0007] Preferably, the outer ring reinforcing rib is located outside the inner ring reinforcing rib, and there are two inner ring reinforcing ribs in total.

[0008] Preferably, the outer ring reinforcing rib is located on the side of the through hole away from the middle of the flange rubber ring body, and both inner ring reinforcing ribs are located between the through hole and the middle of the flange rubber ring body.

[0009] Preferably, the upper sides of both the inner and outer ring reinforcing ribs are arc-shaped, and the two inner ring reinforcing ribs are connected by a connecting rib.

[0010] Preferably, the first connecting rib is equidistantly arranged on one side of the two inner ring reinforcing ribs, and the outer ring reinforcing rib is equidistantly connected to the inner ring reinforcing rib on the adjacent side by a second connecting rib and a reinforcing rib.

[0011] Preferably, each of the reinforcing bars has a reserved hole inside, and the reserved hole and the through hole are arranged on the same vertical line.

[0012] Preferably, an elastic reinforcing rib connects the second connecting rib to the reinforcing rib, and the number of the elastic reinforcing ribs is the sum of the number of the second connecting rib and the number of the reinforcing rib.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The flange rubber ring with a centrally located force-bearing structure has a shape that fits the arc surface of the double-sided irregular flange, and is provided with an outer ring reinforcing rib and an inner ring reinforcing rib for centrally distributed force. During use, the support and sealing effects are better. At the same time, the connecting rib one, connecting rib two, and reinforcing rib, as well as the elastic reinforcing rib for enhancing elasticity, can further enhance the support and sealing effects during use. This solves the problem that using a flat rubber ring during the assembly of double-sided irregular flanges can lead to uneven force distribution on the double-sided irregular flanges, resulting in a decrease in assembly accuracy.

[0014] 1. This flange rubber ring with a centrally located force-bearing structure is designed to facilitate the fit between the flange rubber ring body and the double-sided irregular flange. The protrusions and grooves of the flange rubber ring body fit with the arc-shaped surface of the double-sided irregular flange, ensuring high fit on different cylinder bodies. At the same time, the outer ring reinforcing ribs and inner ring reinforcing ribs can effectively improve the support effect of the flange rubber ring body. The arc-shaped setting on the upper side of the outer ring reinforcing ribs and inner ring reinforcing ribs can effectively distribute the pressure along the arc-shaped surface, thereby achieving a good centrally located force-bearing effect. The flange rubber ring with a centrally located force-bearing structure has a shape that fits with the arc-shaped surface of the double-sided irregular flange. In addition, the flange rubber ring body is internally connected with outer ring reinforcing ribs and inner ring reinforcing ribs that can centrally distribute the pressure. When in use, the support and sealing effects are better.

[0015] 2. This flange rubber ring with a centrally located load-bearing structure, to further enhance the compressive strength of the flange rubber ring body, is connected by connecting rib 2, reinforcing rib, and connecting rib 1 between the outer ring reinforcing rib and the inner ring reinforcing rib, as well as between the inner ring reinforcing ribs. This ensures that the flange rubber ring body will not be excessively compressed or stretched under the pressure of gravity. At the same time, the elastic reinforcing rib further enhances the elastic support effect of the flange rubber ring body. This flange rubber ring with a centrally located load-bearing structure is equipped with connecting rib 1, connecting rib 2, reinforcing rib, and elastic reinforcing rib to enhance the elasticity effect, which can further strengthen the support and sealing effect during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution: a flange rubber ring with a centrally located force-bearing structure, comprising a flange rubber ring body 1, an outer ring reinforcing rib 2, and an inner ring reinforcing rib 201.

[0023] The flange rubber ring body 1 has symmetrically arranged protrusions 101 and grooves 102 on its upper side. The flange rubber ring body 1 has through holes 103 equidistantly opened inside. The flange rubber ring body 1 has an outer ring reinforcing rib 2 and an inner ring reinforcing rib 201 connected inside. The flange rubber ring body 1 has an opening in the middle. The outer ring reinforcing rib 2 is located outside the inner ring reinforcing rib 201, and there are two inner ring reinforcing ribs 201. The outer ring reinforcing rib 2 is located on the side of the through hole 103 away from the opening in the middle of the flange rubber ring body 1. Both inner ring reinforcing ribs 201 are located between the through hole 103 and the opening in the middle of the flange rubber ring body 1. The upper sides of the inner ring reinforcing rib 201 and the outer ring reinforcing rib 2 are arc-shaped.

[0024] In practical implementation, to facilitate the fit between the flange rubber ring body 1 and the double-sided irregular flange, during the manufacturing of the flange rubber ring body 1, the shape, size, and surface roughness data of the large filter cylinder body surface are accurately obtained to achieve precise design of the gasket arc surface. Based on the precise curvature data, the optimal curvature is determined through simulation analysis, and a flange rubber ring body 1 with protrusions 101 and grooves 102 with a reasonable tolerance range is designed to fit the arc surface of the double-sided irregular flange, ensuring high fit on different cylinder bodies. At the same time, the inner and outer sides of the through hole 103 of the flange rubber ring body 1 are respectively provided with external... The outer ring reinforcing rib 2 and inner ring reinforcing rib 201 can effectively improve the support effect of the flange rubber ring body 1. The arc-shaped setting on the upper side of the outer ring reinforcing rib 2 and inner ring reinforcing rib 201 can effectively distribute the pressure along the arc surface, thereby achieving a good central force distribution effect. The flange rubber ring with the central force distribution structure has a shape that fits the arc surface of the double-sided irregular flange. Moreover, the flange rubber ring body 1 is internally connected with the outer ring reinforcing rib 2 and inner ring reinforcing rib 201, which can centrally distribute the pressure. Therefore, the support and sealing effects are better when in use.

[0025] See Figure 3 and Figure 4 It can be seen that the two inner ring reinforcing ribs 201 are connected by connecting rib 1 202. The connecting rib 1 202 is equidistantly arranged on the adjacent side of the two inner ring reinforcing ribs 201. The outer ring reinforcing rib 2 is equidistantly connected to the inner ring reinforcing rib 201 on the adjacent side by connecting rib 223 and reinforcing rib 204. Each of the reinforcing ribs 204 has a reserved hole 205, and the reserved hole 205 and the through hole 103 are arranged on the same vertical line. The connecting rib 223 and the reinforcing rib 204 are connected by an elastic reinforcing rib 206. The number of elastic reinforcing ribs 206 is the sum of the number of connecting rib 223 and reinforcing rib 204.

[0026] In specific implementation, to further enhance the compressive strength of the flange rubber ring body 1, connecting rib 203, reinforcing rib 204, and connecting rib 1 202 are respectively connected between the outer ring reinforcing rib 2 and the inner ring reinforcing rib 201, as well as between the inner ring reinforcing rib 201 and the inner ring reinforcing rib 201. This ensures that the flange rubber ring body 1 will not be excessively compressed or stretched under the pressure of gravity. At the same time, the reinforcing rib 204 and the reserved hole 205 inside the reinforcing rib 204 can strengthen the area around the through hole 103 and prevent damage to the through hole 103. The elastic reinforcing rib 206 can further enhance the elastic support effect of the flange rubber ring body 1. This flange rubber ring with a centrally stressed structure is provided with connecting rib 1 202, connecting rib 203, and reinforcing rib 204 for reinforcement and elastic reinforcing rib 206 for enhancing elasticity. In use, it can further enhance the support and sealing effect.

[0027] In summary, when using this flange rubber ring with a centrally located force-bearing structure, the shape of the flange rubber ring body 1 fits the arc surface of the double-sided irregular flange, and the flange rubber ring body 1 is internally connected with an outer ring reinforcing rib 2 and an inner ring reinforcing rib 201 that can centrally distribute the force. This results in better support and sealing effects during use. Furthermore, the connecting rib 1 202, connecting rib 203, and reinforcing rib 204 can connect the outer ring reinforcing rib 2 and the inner ring reinforcing rib 201, as well as the inner ring reinforcing rib 201 and the inner ring reinforcing rib 201, thereby improving the overall support effect of the flange rubber ring body 1.
