Adding an alloy element to aluminum can change its organizational structure and performance. It is suitable for various processed materials or casting parts. Aluminum alloys are widely used in daily life. Some flanges used for pipe connections are usually made of aluminum alloys.

[0003] The Chinese patent discloses an aluminum alloy flange with a sealing structure (authorization announcement number CN217177801U), including a flange body, the flange body including a first connection plate, a second connection plate, a sealing seat and a connection groove, a plurality of first mounting holes are opened in the middle of the first connection plate, a plurality of second mounting holes are opened in the middle of the second connection plate, and the sealing seat includes a rubber ring, a sealing outer gasket and an inner hoop;

[0004] Although the surfaces of the first connecting plate and the second connecting plate are tightly fitted together by providing a first connecting plate, a second connecting plate, a sealing seat, a connecting groove and a waterproof sealing film, when the flow rate of the medium flowing through the flange-connected pipe is too fast, it will easily cause slight shaking of the flange connection, and then cause the flange to rub against the sealing ring. If things go on for a long time, it will easily cause the sealing ring to shift, break, or rupture, thereby reducing the sealing performance of the connection. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides an aluminum alloy flange with a sealing structure, including a first flange 1 and a second flange 2, wherein a pipe 3 is fixedly installed at one end of the first flange 1 and the second flange 2 away from each other, and a plurality of bolt components 15 are annularly installed between the first flange 1 and the second flange 2, wherein the number of the bolt components 15 is eight, and the first flange 1 and the second flange 2 are disassembled and installed by means of the plurality of bolt components 15.

[0024] A sealing assembly is provided between the first flange 1 and the second flange 2. The sealing assembly is buckled and fixedly connected to the inner ring rubber strip 4 and the outer ring rubber strip 5 on the side of the first flange 1 facing the second flange 2. The inner ring rubber strip 4 and the outer ring rubber strip 5 are connected and fixed to the first flange 1 by gluing. A main sealing protrusion 6 and an auxiliary sealing protrusion 10 are fixedly connected to the side of the second flange 2 facing the first flange 1. The materials of the main sealing protrusion 6 and the auxiliary sealing protrusion 10 are the same as those of the inner ring rubber strip 4 and the outer ring rubber strip 5, and they are all bonded and fixed to the second flange 2 by gluing. The main sealing protrusion 6 is slidably mounted between the inner ring rubber strip 4 and the outer ring rubber strip 5. After the installation and fixation between the first flange 1 and the second flange 2 are achieved, the sliding mounting between the main sealing protrusion 6 and the inner ring rubber strip 4 and the outer ring rubber strip 5 can ensure the sealing of the connection between the first flange 1 and the second flange 2. The outer ring rubber strip 5 is slidably mounted between the main sealing protrusion 6 and the auxiliary sealing protrusion 10. The sliding mounting between the outer ring rubber strip 5 and the main sealing protrusion 6 and the auxiliary sealing protrusion 10 can further improve the sealing of the connection between the first flange 1 and the second flange 2.

[0025] Four positioning grooves 7 are equidistantly provided in an annular shape on the outer side of the inner rubber ring 4, and four positioning blocks 8 are equidistantly fixedly connected to the inner side of the main sealing protrusion 6. The height of the positioning block 8 is slightly higher than that of the main sealing protrusion 6. The four positioning blocks 8 are respectively inserted into the four positioning grooves 7. The insertion between the positioning blocks 8 and the positioning grooves 7 can limit the position and angle of the first flange 1 and the second flange 2 during installation. Four arc-shaped protrusions 9 are equidistantly fixedly connected to the outer side of the outer rubber ring 5, and four arc-shaped grooves 11 are equidistantly provided in an annular shape on the inner side of the auxiliary sealing protrusion 10. The four arc-shaped protrusions 9 are respectively slidably sleeved in the four arc-shaped grooves 11. The sliding sleeve between the arc-shaped protrusions 9 and the arc-shaped grooves 11 can improve the connection tightness between the inner rubber ring 4, the outer rubber ring 5, the main sealing protrusion 6 and the auxiliary sealing protrusion 10 to a certain extent.

[0026] Two shock-absorbing plates 12 are symmetrically slidably sleeved between the inner rubber ring 4 and the outer rubber ring 5. The shock-absorbing plates 12 are made of hard rubber. Both shock-absorbing plates 12 are fitted between the first flange 1. A plurality of springs 13 and telescopic rods 14 are equidistantly fixedly connected to the inner ring of the shock-absorbing plates 12. The number of the springs 13 and the telescopic rods 14 is the same, and both are not less than twelve. One end of the plurality of springs 13 and the telescopic rods 14 are fixedly connected to the outer side of the main sealing protrusion 6. By utilizing the telescopic performance of the springs 13 and the telescopic rods 14, the shock-absorbing plates 12 can be made more horizontal when telescopically moving between the inner rubber ring 4 and the outer rubber ring 5.

[0027] The working principle and process of this utility model are as follows:

[0028] During use, during the process of installing the second flange 2 to the first flange 1, the user needs to insert the two shock-absorbing plates 12 and the main sealing protrusion 6 between the inner ring rubber strip 4 and the outer ring rubber strip 5 on the first flange 1, and at the same time, the four positioning blocks 8 are respectively aligned with the four positioning grooves 7 and inserted, and the outer ring rubber strip 5 is inserted between the main sealing protrusion 6 and the auxiliary sealing protrusion 10, and at the same time, the multiple arc-shaped protrusions 9 are respectively aligned with the arc-shaped grooves 11 and inserted, and finally, the first flange 1 and the second flange 2 are installed and fixed by using multiple bolt components 15. At this time, the first flange 1 is fitted with the two shock-absorbing plates 12, and under the extrusion pressure of the first flange 1, the multiple springs 13 and the telescopic rods 14 are compressed. With the cooperation of multiple components, the sealing performance of the connection between the first flange 1 and the second flange 2 can be greatly improved.

[0029] The impact of the medium flow rate will cause the first flange 1 and the second flange 2 to move slightly closer to or away from each other. At this time, under the elastic potential energy of the spring 13, the first flange 1 and the two shock-absorbing plates 12 can always maintain a fit state, effectively ensuring the sealing stability of the first flange 1 and the second flange 2 after being connected.
