Abstract
The utility model discloses a kind of novel damping expansion joint, including inside lining sleeve, bellows and two groups of ear mount flanges, the bellows is arranged on the outside of inside lining sleeve, and two groups of ear mount flanges set up separately at the both ends of bellows.The waveform of the bellows is in " Ω " shape, decoupling rod is set between two groups of ear mount flanges, the decoupling rod passes through the connecting hole of two groups of ear mount flanges, and fixation is attached by fastening connection piece, the fastening connection piece includes spring washer, rubber washer and fastening bolt, the spring washer is pressed on ear mount flange, and rubber washer is pressed on spring washer, and fastening bolt is pressed on rubber washer.The bellows of the utility model uses thin wall multi-layer condensation wave structure, and flexible, compensation rate is big.The both ends connecting flange and ear mount of the utility model are overall structure, and ear mount and pull rod can bear the thrust that bellows deformation generates, meet the intensity requirement of product.
Description
Technical field
The utility model relates to field of mechanical technique, are to be related to a kind of novel damping expansion joint more particularly.
Background technique
Damping expansion section is mainly used for that displacement is small, and the big vibratility of noise frequently pumps inlet and outlet, is mainly used for reducing pipe
The vibration of road system and noise.Currently, traditional pump inlet and outlet generally use rubber compensator, and there is not for rubber compensator
Hygienic, easy to aging, delamination tearing, high voltage performance are poor, service life short equal fatal defects, especially for heat supply, hot duct
Rubber compensator is gradually substituted by novel damping expansion joint.
Universal FlexbleJoint is due to process equipment condition limitation, the absorbable pipe of flexible bellow produced in the market
Axial, lateral, the angular thermal deformation in road, absorbs vibration, reduces noise, resistance to higher pressure and temperature, because flexible bellow uses
Single layer stainless steel axial rigidity it is big, damping noise reduction effect not as good as rubber mend device.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of novel damping for prior art deficiency and defect
Expansion joint, bellows use thin wall multi-layer condensation wave structure, and flexible, compensation rate is big, the spring pad being arranged by decoupling rod both ends
Effective cooperation of circle, rubber washer, the vibration energy generated using the flexible absorbent system of spring and rubber.
Technical solution: to achieve the goals above, the technology employed by the present utility model is a kind of novel damping is swollen
Swollen section, including inside lining sleeve, bellows and two groups of ear mount flanges, the bellows are arranged on the outside of inside lining sleeve, two groups of ear mounts
Flange sets up separately at the both ends of bellows.The waveform of the bellows is in " Ω " shape, and damping is arranged between two groups of ear mount flanges
Bar, the decoupling rod passes through the connecting hole of two groups of ear mount flanges, and is attached fixation by fastening connection piece, and the fastening connects
Fitting includes spring washer, rubber washer and fastening bolt, and the spring washer is pressed on ear mount flange, and rubber washer is pressed in bullet
On spring washer, fastening bolt is pressed on rubber washer.
The decoupling rod is hydraulic telescopic rod.
The bellows is single layer stainless steel flexible bellow.
The utility model has the advantages that the utility model is compared with prior art, the beneficial effect is that:
1, the bellows of the utility model uses thin wall multi-layer condensation wave structure, and flexible, compensation rate is big.
2, the both ends connecting flange of the utility model and ear mount are overall structure, and ear mount and pull rod can bear bellows deformation
The thrust of generation meets the intensity requirement of product.
3, the utility model passes through effective cooperation of spring washer, rubber washer, utilizes the flexible absorbent of spring and rubber
The vibrational energy that system generates, can be prevented while meeting damping requirement bellows because deform it is too big caused by extrusion deformation, this
Design efficiently reduces vibration and the noise of pipe-line system, which improves design side on general compensator
Case does not increase excessive material and but has the characteristics of good damping effect, greatly improves the competitiveness of product, is easily widely popularized
It uses.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of novel damping expansion joint of the utility model.
Specific embodiment
With reference to embodiment, the utility model is further illustrated.
As shown in Figure 1, a kind of novel damping expansion joint, including inside lining sleeve 3, bellows 2 and two groups of ear mount flanges 1, it is described
The setting of bellows 2 is set up separately in 3 outside of inside lining sleeve, two groups of ear mount flanges 1 at the both ends of bellows 2.The wave of the bellows 2
Shape is in " Ω " shape, and decoupling rod 4 is arranged between two groups of ear mount flanges 1, and the decoupling rod 4 passes through the company of two groups of ear mount flanges 1
Hole is connect, and fixation is attached by fastening connection piece, the fastening connection piece includes spring washer 5, rubber washer 6 and fastening
Bolt 7, the spring washer 5 are pressed on ear mount flange 1, and rubber washer 6 is pressed on spring washer 5, and fastening bolt 7 is pressed in rubber
On washer 6.
The decoupling rod 4 is hydraulic telescopic rod.
The bellows 2 is single layer stainless steel flexible bellow.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This is practical
Novel technical scope is not limited to the contents of the specification, it is necessary to determine that its is technical according to scope of the claims
Range.
