Description
Technical Field
[0001] This utility model relates to the field of flanges, and in particular to a flange with a sound-absorbing groove. Background Technology
[0002] A flange is typically a disc-shaped metal connector. Flanges are commonly used to connect pipes, equipment, or mechanical components, achieving sealing and fixation through bolts and gaskets.
[0003] However, in practical applications, existing flanges have obvious noise problems. When fluid flows at high speed in the pipeline or when the equipment vibrates during operation, the flange connection will generate a lot of noise due to fluid impact, mechanical vibration and other reasons. This noise not only pollutes the working environment and affects the physical and mental health and work efficiency of the staff, but may also mask abnormal sounds during equipment operation, making it difficult to detect potential equipment failures in a timely manner.
[0004] Currently, although there are some noise reduction measures, such as wrapping sound insulation material at the flange connection, this method affects the observation of the flange's usage. Therefore, it is necessary to set up sound-absorbing grooves on the flange for direct sound absorption. Utility Model Content
[0005] The purpose of this invention is to provide a flange with a sound-absorbing groove to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a flange with a sound-absorbing groove, comprising: A flange, wherein the top of the flange is provided with mounting holes arranged in a ring array; An auxiliary mechanism, located on top of the flange, is used to provide noise reduction protection for the flange. The auxiliary mechanism includes: A sound-absorbing cylinder, which is fixedly connected to the top of the flange; A sound-absorbing groove is formed on the top of the flange; A sound-absorbing component, which is located inside the sound-absorbing cylinder.
