One ", " second ", " third " are then used for description purposes only, and are not understood to indicate or imply relative importance.
Referring to Figures 1 and 2, this is the embodiment of the present invention a1, specifically：
A kind of vibration damping bellows, including upper tube body 1 and metal drum 2, the lower face of upper tube body are fixed with multistage metal bar
4, multistage metal bar includes top 41, middle part 42 and lower part 43, and the upper, middle and lower is the cylinder of concentrically axis
The upper, middle and lower of body, the multistage metal bar is integrally formed, top and the upper tube body of the multistage metal bar
Lower face welding, the diameter of the upper and lower part is all higher than the diameter at the middle part；The upper surface of the metal drum is equipped with
Circular open 21, by the circular open, the middle part and lower part of multistage metal bar are placed to described the multistage metal bar
In metal drum, spring 5 is externally provided in the middle part of the multistage metal bar in metal drum, the outer diameter of the spring is more than the circle
The diameter of opening, the outer diameter of spring are not more than the diameter of the lower part of the multistage metal bar so that spring is using middle part as guide post, frame
It is located between lower part and circular open；It is filled with damping fluid 6 in the metal drum, damping fluid is full of metal drum, under metal drum
End face is fixed with lower tube body 3, and lower tube body of the invention is preferably welded with the lower face of metal drum.The upper tube body is under
Tube body is metal bellows, and metal bellows has good flexibility, is less likely to occur to be broken after vibrated；And gold
The vertical rigidity for belonging to bellows is higher than general metal tube, can bear the vertical motion of bigger and heavier pipeline weight
Amount.Since in the vibration absorber present invention is generally used in pipeline, working environment is mostly the space of humidity, therefore in order to avoid this hair
Bright important parts get rusty, and the multistage metal bar is multistage rod iron, and the metal drum is steel drum, and the metal bellows is
Corrugated stainless steel tubing.Using the above structure, beneficial effects of the present invention：Present invention employs springs to subtract with what damping fluid was combined
It shakes mode, spring has flexibility, can reduce the acceleration of pipeline, but since the inherent damping of spring is small, the increasing of damping fluid
If the damped coefficient of the present invention can be improved, damping fluid can absorb well and dissipation supporting surface on the energy that transmits so that
The present invention has larger vertical rigidity and damping, the vibration being effectively isolated between pipeline and supporting surface.Structure of the invention letter
It is single, cheap, effectiveness in vibration suppression is superior, be suitable for all kinds of pipelines vibration absorber.
Due to the upper weld of the lower face and the multistage rod iron of the upper tube body, the top of multistage rod iron it is straight
Diameter is not less than the outer diameter of upper tube body, and upper lobes lead to cut hand in order to prevent, the diameter on top preferably with the outer diameter of upper tube body one
It causes, the central axis on top is overlapped with the central axis of upper tube body；In order to reduce production cost, the upper tube body is with lower tube body
The consistent corrugated stainless steel tubing of model, the central axis of upper tube body and the central axis of lower tube body are kept as possible in working condition
It overlaps.Since the lower face of the steel drum is welded with the lower tube body, the steel drum is cylinder, therefore the outer diameter of steel drum is not small
In the outer diameter of lower tube body, in order to improve welding rigidity, the outer diameter of steel drum is preferably greater than the outer diameter of lower tube body.
The diameter of the lower part of multistage rod iron and the outer diameter of spring are all higher than the diameter of the circular open, combination of the invention
Installation process is：Multistage rod iron and spring are placed to first in double steel drum, are then welded two double of steel drums
At a steel drum, it is last toward at the circular open of steel drum to filling damping fluid inside steel drum.
It is further used as preferred embodiment, upper surface and the supporting surface holder of the upper tube body weld, supporting surface branch
Frame is bolted under supporting surface, and the lower tube body is welded with pipeline support, and pipe-support frame plays fixed support to pipeline
Effect.The present invention is between supporting surface and pipeline, and vibration on supporting surface is only few due to after the dissipation of damping fluid
The vibrational energy of amount passes on pipeline, and deficiency causes the lasting resonance of pipeline, prevents pipeline and is ruptured because of lasting resonance；
Meanwhile the vibration on pipeline is due to after the energy-absorbing of spring, reducing influence of the vibrational energy to supporting surface so that supporting surface
Vibration frequency reduce, vibrating noise is reduced, and both last vibration reaches dynamic equilibrium, and supporting surface-pipe-line system is maintained at
It is vibrated under lower energy rank.
The better embodiment of the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications or be replaced under the premise of without prejudice to spirit of that invention
It changes, these equivalent modifications or replacement are all contained in the application claim limited range.
