Description

A stainless steel flange Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a stainless steel flange. Background Technology

[0002] A flange, often simply called a flange, is a general term that typically refers to a disc-shaped metal body with several holes around its perimeter for fixing and connecting other components. It is widely used in machinery.

[0003] Stainless steel flanges are a common type of flange. Existing stainless steel flanges have poor vibration damping performance, resulting in weak resistance to external vibrations. When vibration occurs in the equipment or pipelines connected to the flange, it can easily cause fatigue damage to the flange and loosen the bolts installed on it. Therefore, there is an urgent need to develop a stainless steel flange with good vibration damping performance, reducing fatigue damage caused by vibration and preventing bolt loosening due to vibration, to overcome the shortcomings in current practical applications and meet current needs. Summary of the Invention

[0004] The purpose of this utility model is to provide a stainless steel flange to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stainless steel flange includes a stainless steel disc and an elastic buffer disc. There are two stainless steel discs, and the elastic buffer disc is bonded and fixed between the two stainless steel discs. A storage cavity is provided inside the stainless steel disc, and the storage cavity stores damping fluid. The elastic buffer disc is provided with a plurality of blocking holes, and the blocking holes are hexagonal in shape.

[0007] Preferably, the elastic buffer disc is made of silicone rubber.

[0008] Preferably, the stainless steel tray has a filling port that communicates with the storage cavity, and a plug is detachably installed on the filling port by means of threads.

[0009] Preferably, multiple insertion posts are fixed on both the front and rear sides of the elastic buffer plate, and multiple insertion holes for inserting the insertion posts are provided on the stainless steel plate.

[0010] Preferably, multiple rubber sleeves are fixedly installed on the stainless steel disc, and multiple mounting holes are provided on the elastic buffer disc. The multiple rubber sleeves and multiple mounting holes are aligned one by one, and the rubber sleeves and mounting holes are used for bolts to pass through.

[0011] The beneficial effects of this invention are as follows: When the stainless steel flange is subjected to external vibration, the damping fluid in the storage cavity will undergo relative movement, resulting in friction and viscosity forces within the damping fluid and between the damping fluid and the cavity wall. These forces can convert the mechanical energy of the vibration into heat energy, thereby consuming vibration energy and achieving the purpose of vibration reduction. In addition, the elastic buffer plate deforms under the action of vibration force to buffer and absorb the vibration. The setting of the blocking holes can disrupt the propagation path of the vibration force, causing the vibration to be reflected and refracted at the blocking holes, further consuming vibration energy and reducing fatigue damage to the flange. Furthermore, the rubber sleeve can further absorb the vibration, thereby reducing the impact of vibration on the bolts and preventing bolt loosening. In summary, this invention has good vibration reduction performance, reduces fatigue damage caused by vibration, and can prevent bolt loosening caused by vibration. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] Referring to Figures 1 to 5, in this embodiment of the present invention, a stainless steel flange includes a stainless steel disc 1 and an elastic buffer disc 2. There are two stainless steel discs 1, and an elastic buffer disc 2 is bonded and fixed between the two discs. The elastic buffer disc 2 is made of silicone rubber, giving it good elastic damping function. A storage cavity 104 is provided inside the stainless steel disc 1, and damping fluid is stored in the storage cavity 104. A filling port 102 connected to the storage cavity 104 is fixed on the stainless steel disc 1. A plug 103 is detachably installed on the filling port 102 via threads. Damping fluid can be added to the storage cavity 104 by removing the plug 103. The elastic buffer disc 2 is provided with multiple blocking holes 203, which are hexagonal in shape. When the elastic buffer disc 2 is subjected to compression and vibration, the blocking holes 203 can disrupt the propagation path of the vibration force, causing the vibration to be reflected and refracted at the blocking holes 203, further consuming the vibration energy.

[0022] Multiple insertion posts 201 are fixed on both the front and rear sides of the elastic buffer disk 2, and multiple insertion holes 101 are provided on the stainless steel disk 1 for inserting the insertion posts 201 (the insertion holes 101 are not connected to the storage cavity 104).

[0023] Multiple rubber sleeves 3 are fixedly installed on the stainless steel disc 1, and multiple mounting holes 202 are provided on the elastic buffer disc 2. The multiple rubber sleeves 3 and the multiple mounting holes 202 are aligned one by one. The rubber sleeves 3 and the mounting holes 202 are used for bolts to pass through. When affected by external vibration, the rubber sleeves 3 can absorb the vibration to a certain extent and reduce the vibration transmitted to the bolts.

[0024] Working principle: When the stainless steel flange is subjected to external vibration, the damping fluid in the storage cavity 104 will generate relative movement, which will generate friction and viscosity between the damping fluid and the cavity wall of the storage cavity 104. These forces can convert the mechanical energy of the vibration into heat energy, thereby consuming vibration energy and achieving the purpose of vibration reduction. In addition, the elastic buffer plate 2 deforms under the action of vibration force to buffer and absorb the vibration. The setting of the blocking hole 203 can disrupt the propagation path of the vibration force, so that the vibration is reflected and refracted at the blocking hole 203, further consuming the vibration energy, thereby reducing the fatigue damage of the flange. Furthermore, the rubber sleeve 3 can further absorb the vibration, thereby reducing the impact of vibration on the bolts and preventing the bolts from loosening.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
