[0002] A high-speed flange is a connecting piece used to connect components such as pipelines and equipment, and is usually used in high-speed fluid transmission or high-speed rotating equipment. Under high-speed operating conditions, the flange needs to bear large pressures and impact forces. Therefore, high-speed flanges are usually made of high-strength materials such as alloy steel and stainless steel. These materials have high strength and hardness and can withstand various stresses during high-speed operation. High-speed flanges are widely used in the petrochemical industry, the petrochemical industry, etc.

[0003] Existing high-speed flanges will generate noise due to friction during operation. After the high-speed flange is connected to a pipeline or equipment, with the operation of the system, friction will occur between the flange connection surfaces and between the flange and other components due to relative movement. This friction will generate mechanical vibrations, which will be converted into noise. Currently, mostly only a single sound-absorbing cotton is used for noise reduction treatment, but the noise reduction effect of this method is not good. Summary of the Utility Model

When in use, the two high-speed flange plates 1 are connected together by the bolt 14, and the annular gaskets 16 on the two high-speed flange plates 1 are in close contact, which can effectively reduce the vibration generated by the high-speed flange plate 1 during use, thereby achieving the effect of noise reduction. The annular gasket 16 is made of rubber, and rubber has good elasticity and damping performance, and can effectively absorb impact and vibration energy, playing a role in shock absorption and buffering. A sound-absorbing block 2 is fixedly connected to the upper surface of the high-speed flange plate 1. The number of the sound-absorbing blocks 2 is multiple and they are annularly distributed. A sound-absorbing pipe 3 is arranged inside the sound-absorbing block 2. A sound-absorbing gasket 4 is fixedly connected to the inner surface of the sound-absorbing pipe 3. The sound-absorbing gasket 4 is made of polyurethane. The polyurethane sound-absorbing gasket 4 has excellent sound-absorbing performance and heat-insulating performance, and can effectively reduce the transmission of noise and heat. A sound-absorbing groove 5 is arranged inside the sound-absorbing block 2. The sound-absorbing pipe 3 is communicated with the sound-absorbing groove 5. A sound-absorbing cotton 6 is fixedly connected to the inner surface of the sound-absorbing groove 5. The number of the sound-absorbing cottons 6 is two and they are distributed up and down. The sound-absorbing cotton 6 is made of glass fiber. The glass fiber sound-absorbing cotton 6 has the characteristics of non-combustibility, corrosion resistance, high temperature resistance, etc., and is soft in texture, easy to process and install. A heat-conducting plate 7 is fixedly connected to the inner surface of the sound-absorbing block 2, and a heat-dissipating plate 8 is fixedly connected to the inner surface of the sound-absorbing block 2. The vibration generated during the use of the high-speed flange plate 1 is transmitted into the sound-absorbing groove 5 through the sound-absorbing block 2, the sound-absorbing pipe 3 and the sound-absorbing gasket 4, and is sound-absorbed by the sound-absorbing cotton 6. The sound-absorbing cotton 6 can effectively absorb the sound wave energy and reduce the intensity of the noise. When the vibration is transmitted into the sound-absorbing cotton 6, it will cause the molecular vibration of the material, thereby generating heat energy. The generated heat energy is conducted through the heat-conducting plate 7 and dissipated through the heat-dissipating plate 8. A first annular groove 9 is arranged inside the high-speed flange plate 1, a buffer piece 10 is fixedly connected to the bottom inner wall of the first annular groove 9.

[0023] Working principle: When in use, two high-speed flanges 1 are connected together by bolts 14. The annular gaskets 16 on the two high-speed flanges 1 are in close contact, which can effectively reduce the vibration generated by the high-speed flanges 1 during use, thereby achieving a noise reduction effect. During the use of the high-speed flanges 1, the generated vibration is transmitted to the sound absorption groove 5 through the sound absorption block 2, the sound absorption pipe 3, and the sound absorption gasket 4, and is absorbed by the sound absorption cotton 6. The sound absorption cotton 6 can effectively absorb the sound wave energy and reduce the intensity of the noise. When the vibration is transmitted to the sound absorption cotton 6, it will cause the molecular vibration of the material, thereby generating heat energy. The generated heat energy is conducted through the heat conduction plate 7 and dissipated through the heat dissipation plate 8, so as to reduce the temperature in the sound absorption groove 5. At the same time, during the use of the high-speed flanges 1, the generated vibration is transmitted to the bolts 14, and under the action of the buffer sheet 10 and the rubber gasket 12, the vibration of the bolts 14 can be effectively reduced, and the stability of the bolts 14 during use can be maintained. This structure can effectively reduce the propagation of noise during the operation of the high-speed flange 1, reduce the noise level, improve the working environment, reduce the noise interference to the staff, and when in use, the setting of the buffer sheet 10 and the rubber gasket 12 can increase the friction force between the bolts 14 and the high-speed flanges 1, protect the stability of the connection between the bolts 14 and the high-speed flanges, prevent the bolts 14 from loosening, and further achieve the effect of shock absorption and noise reduction.
