Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flanges, and particularly relates to an aluminum flange with anti-rotation grooves. Background Technique
[0002] In the existing pipeline connection technology, as a key component, the flange is widely used in industrial fields such as petroleum, chemical industry, and natural gas. However, under specific working conditions, such as high pressure, high temperature, strong vibration and other environments, traditional flanges often face the problem of insufficient connection stability. Due to the action of these harsh conditions, the flange connection often loosens, rotates, and even the seal fails, resulting in fluid leakage, equipment damage and safety hazards.
[0003] Specifically, when the pipeline system is subjected to external force impact or long-term vibration, the bolt connection of the traditional flange may become loose and lose its fastening effect, thereby causing the flange to rotate and destroying the original sealing structure. In addition, under extreme temperature conditions, the thermal expansion and contraction of the flange material may also cause the gap at the connection to increase, further reducing the sealing performance. Content of the Utility Model
[0004] The main purpose of the utility model is to provide an aluminum flange with anti-rotation grooves, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] An aluminum flange with anti-rotation grooves, including flange one, one end of the flange one is provided with flange two, a gasket is arranged between the flange one and the flange two, a plurality of through cavities are respectively drilled at the outer sides of the flange one, the flange two and the gasket, bolt assemblies are arranged between the parallel through cavities, the flange one, the flange two and the gasket are respectively detachably connected through the bolt assemblies on the through cavities, a plurality of anti-rotation blocks are fixed on the side of the flange one close to the flange two, grooves one are respectively drilled at the positions of the flange one outside the anti-rotation blocks, two outer ring grooves are respectively drilled at the outer wall of the end of the anti-rotation block far from the flange one, rubber rings are respectively sleeved at the positions of the outer ring grooves, through holes are respectively drilled at the positions of the gasket corresponding to the anti-rotation blocks, half rubber rings are respectively arranged on both sides of the through holes of the gasket, anti-rotation grooves are respectively drilled on one side of the flange two corresponding to the anti-rotation blocks, grooves two are respectively drilled at the outer sides of the anti-rotation grooves of the flange two, and two inner ring grooves are respectively drilled inside the anti-rotation grooves.
[0007] Preferably, the anti-rotation blocks respectively communicate with the through holes with matching positions, and the ends of the anti-rotation blocks passing through the through holes are respectively inserted into the anti-rotation grooves with matching positions.
[0008] Preferably, the inner walls of the rubber rings are respectively in contact with the inner walls of the outer ring grooves, and the outer walls of the rubber rings are respectively in contact with the inner walls of the inner ring grooves.
[0009] Preferably, the half rubber rings on one side of the washer are respectively inserted into the interior of the first groove.
[0010] Preferably, the half rubber rings on the other side of the washer are respectively inserted into the interior of the second groove.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. After the first flange, the second flange and the washer are connected together by the bolt assembly, the anti-rotation block can be inserted into the anti-rotation groove, forming a mechanical locking effect. This locking mechanism can effectively prevent the first flange and the second flange from rotating or loosening when subjected to external forces, thereby improving the stability and reliability of the connection.
[0013] 2. After the first flange, the second flange and the washer are connected together by the bolt assembly, the contact surfaces of the washer with the first flange and the second flange are provided with half rubber rings. The half rubber rings on both sides can be respectively inserted into the interior of the first groove and the second groove, increasing the sealing and protection performance, and at the same time making the first flange and the washer and the second flange and the washer have a certain anti-torsion property.
[0014] 3. After the anti-rotation block is inserted into the anti-rotation groove, the rubber ring at the outer ring groove of the outer wall of the anti-rotation block can also be inserted into the interior of the anti-rotation groove and is located inside the inner ring groove of the anti-rotation groove. When the first flange and the second flange vibrate due to external forces and are transmitted through the anti-rotation block, the anti-rotation block in the anti-rotation groove can achieve a certain shock absorption effect by virtue of the presence of the rubber ring, increasing the anti-rotation effect of the anti-rotation block inserted into the anti-rotation groove.

[0022] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.
[0023] As Figure 1-6 shown, an aluminum flange with anti-rotation grooves includes a flange one 1. One end of the flange one 1 is provided with a flange two 2. A gasket 3 is provided between the flange one 1 and the flange two 2. A plurality of through cavities 4 are respectively drilled at the outer sides of the flange one 1, the flange two 2 and the gasket 3. Bolt assemblies 5 are arranged between the parallel through cavities 4. The flange one 1, the flange two 2 and the gasket 3 are respectively detachably connected through the bolt assemblies 5 on the through cavities 4. A plurality of anti-rotation blocks 11 are fixed on the side of the flange one 1 close to the flange two 2. Grooves one 12 are respectively drilled at the positions of the flange one 1 outside the anti-rotation blocks 11. Two outer ring grooves 13 are respectively drilled at the outer wall of the end of the anti-rotation block 11 far from the flange one 1. Rubber rings 6 are sleeved at the positions of the outer ring grooves 13. Through holes 31 are respectively drilled at the positions of the gasket 3 corresponding to the anti-rotation blocks 11. Half rubber rings 32 are arranged on both sides of the through holes 31 of the gasket 3. Anti-rotation grooves 21 are respectively drilled at the side of the flange two 2 corresponding to the anti-rotation blocks 11. Grooves two 22 are respectively drilled at the positions of the flange two 2 outside the anti-rotation grooves 21. Two inner ring grooves 23 are respectively drilled inside the anti-rotation grooves 21.
[0024] Specifically, the anti-rotation blocks 11 are respectively in through communication with the through holes 31 with matching positions, and the ends of the anti-rotation blocks 11 passing through the through holes 31 are respectively inserted into the anti-rotation grooves 21 with matching positions.
[0025] Specifically, the inner walls of the rubber rings 6 are respectively in contact with the inner walls of the outer ring grooves 13, and the outer walls of the rubber rings 6 are respectively in contact with the inner walls of the inner ring grooves 23, providing a certain shock absorption effect.
[0026] Specifically, the semi-rubber rings 32 on one side of the washer 3 are respectively inserted into the interior of the first groove 12, and the semi-rubber rings 32 on the other side of the washer 3 are respectively inserted into the interior of the second groove 22, which increases the sealing performance of the contact between the washer 3 and the first flange 1 and the second flange 2 at the through hole 31.
[0027] Working principle: After the first flange 1, the second flange 2 and the washer 3 are connected together by the bolt assembly 5, the anti-rotation block 11 can be inserted into the anti-rotation groove 21, forming a mechanical locking effect. This locking mechanism can effectively prevent the first flange 1 and the second flange 2 from rotating or loosening when subjected to external forces, thereby improving the stability and reliability of the connection. After the first flange 1, the second flange 2 and the washer 3 are connected together by the bolt assembly 5, the contact surfaces of the washer 3 with the first flange 1 and the second flange 2 are provided with semi-rubber rings 32, and the semi-rubber rings 32 on both sides can be respectively inserted into the interior of the first groove 12 and the second groove 22, increasing the sealing protection. At the same time, it also gives a certain torsional resistance between the first flange 1 and the washer 3 and between the second flange 2 and the washer 3. After the anti-rotation block 11 is inserted into the anti-rotation groove 21, the rubber ring 6 at the outer ring groove 13 of the outer wall of the anti-rotation block 11 can also be inserted into the interior of the anti-rotation groove 21 and is located inside the inner ring groove 23 of the anti-rotation groove 21. When external forces cause vibrations in the first flange 1 and the second flange 2 and are transmitted through the anti-rotation block 11, the anti-rotation block 11 can achieve a certain damping effect by virtue of the presence of the rubber ring 6 in the anti-rotation groove 21, increasing the anti-rotation effect of the anti-rotation block 11 inserted into the anti-rotation groove 21.
