[0002] Bellows mainly include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, shock absorption, and absorption of pipeline settlement deformation, and are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water conservancy, metallurgy and other industries. Plastic and other materials of bellows play an irreplaceable role in the fields of medium transportation, power threading, machine tools, home appliances, etc. When using bellows, due to the shortcomings of their own structure or the requirements of the working environment, compensators need to be installed to compensate for the structural function of the bellows.

[0003] When in use, traditional compensators are usually fixed with rigid guide rod bolts, which will affect the original bending performance of the bellows to a certain extent. At the same time, it may cause loud noise when the bellows is vibrated, and it is difficult to achieve both vibration reduction and noise reduction at the same time. For this reason, the utility model proposes a bellows compensator with vibration reduction and noise reduction effects to solve the above problems. Utility Model Content

[0006] Preferably, a vacuum sound insulation cavity is fixedly connected to the outer side of the spring groove, and the vacuum sound insulation cavity is fixedly sleeved and connected to the inner side of the vibration damping groove.

[0007] Preferably, the vibration-damping grooves are arranged in a circular array and are evenly and fixedly connected to the lower end surface of the middle limiting sleeve.

[0008] Preferably, a buffer sleeve is fixedly connected to the inner ring of the fixing frame, an elastic sleeve is fixedly connected to the inside of the buffer sleeve, and a bellows is provided in the elastic sleeve.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model provides a buffer noise reduction device so that the compensator is flexibly fixed when in use and is interconnected by four damping springs, thereby ensuring the bending performance of the bellows itself. At the same time, since the damping springs can absorb more vibrations, the propagation of noise can be greatly reduced when the bellows is damped, and a vacuum sound insulation chamber is provided to greatly reduce the propagation of sound caused by the vibration of the device itself.
