Description
Technical field
The utility model relates to a kind of bit shift compensation protective gear one complex corrugated pipe expansion joint of hydrodynamic pressure pipeline, and finger is equipped with the improvement structure of the complex corrugated pipe expansion joint of outer sleeve black box especially.
Background technique
The bellows expansion joint that now has been widely used has single entry and compound two big classes.The structural type of complex corrugated pipe expansion joint is to be connected in series by two bellowss.It is fixed with the end pipe of a side respectively by end pipe, the end pipe of both sides inner fixed guide shell, an end that the complex corrugated pipe expansion joint of outer sleeve black box is housed, two bellowss and two outer sleeve assembly formations that the bellows outside is provided with that the other end is connected with middle inner sleeve respectively.The outer sleeve assembly comprises intrinsic filler baffle ring, filler, trim ring and trim ring flange in outer sleeve, the outer intrinsic outer sleeve flange of outer sleeve, the outer sleeve, by the trim ring bolt trim ring flange and outer sleeve flange is connected as one.
This complex corrugated pipe expansion joint deficiency is:
1, because the existence of middle inner sleeve increases whole expansion joint weight, it is just obvious more particularly to work as big more this defective of caliber, and because middle inner sleeve is only supported by the bellows at two ends, the natural frequency of vibration is lower, produces vibration easily and bellows is damaged under flow fluctuation.
2, in use,,, waste time and energy, also increased maintenance cost in case whole guide shell cutting must be scrapped when bellows interior need be overhauled because guide shell is an integral solder with the end pipe.
3, the sliding contact surface between filler and the end pipe is normally on the surface of rubber and paint, and friction factor is big, and easily produces adhesion or damage between paint and the rubber, and the airtight quality of sealing face is descended, and can not in time carry out seal protection to pipeline.
Summary of the invention
The purpose of this utility model is to provide a kind of follow-on complex corrugated pipe expansion joint, and its can weight reduction, improves the natural frequency of vibration of whole expansion joint; The inboard maintenance of bellows needn't destroy whole guide shell, and the sliding sealing surface of filler can not produce the adhesion damage.
In order to achieve the above object, the utility model is performed such.The utility model comprises the two ends pipe that is connected with the upstream and downstream pipeline respectively, here be called inner sleeve, two bellowss affixed with inner sleeve, the outer sleeve black box that is provided with in the bellows outside: the outer sleeve black box is by outer sleeve, the outer sleeve flange, filler baffle ring, filler in the outer sleeve, trim ring and trim ring flange, the trim ring bolt that connects trim ring flange and outer sleeve flange is formed.Its structure outline is: the other end of bellows is affixed with middle outer sleeve by end ring, is consolidated with bolt block on the end ring, by the chek bolt on the bolt block, guide shell firmly is connected with end ring.Guide shell is to be assemblied to form with 3-6 piece guide plate, also has the concora crush hole that reduces fluid fluctuation or water hammer influence in the middle of the every guide plate, is welded to connect plate on the guide plate that the chek bolt place is installed, and makes a retraction guide plate of chek bolt, reduces fluid resistance.The position that inner sleeve surface contacts with filler is consolidated with throat ring, and throat ring is the Clad Steel Plate that stainless steel and carbon steel are composited, with the filler surface of contact be the less stainless steel of friction factor.
Superior functionality of the present utility model is:
1, because the utility model has been removed the intermediate casing between two bellowss, the structural type of this shared outer sleeve has made the weight saving of whole expansion joint, and has improved the natural frequency of vibration of whole expansion joint, the Security of operation is improved.
2, because guide shell of the present utility model is to be assemblied to form with 3-6 piece guide plate, also have the concora crush hole that reduces fluid fluctuation or water hammer influence in the middle of the every guide plate, therefore easy to maintenance, will whole guide shell do not cut off and scrap when bellows is inboard when needing maintenance, but the guide plate of dismounting relevant position just
3, because the throat ring between filler of the present utility model and the inner sleeve is a Clad Steel Plate, with the filler surface of contact be the less stainless steel of friction factor, therefore can reduce the deformation resistance of filler, and the adhesion between filler and the sliding contact surface can not take place.
4, owing to be welded to connect plate on the guide plate that the chek bolt place is installed, the transition by connecting plate so that make the guide plate internal surface smooth, has reduced fluid resistance with a retraction of the chek bolt on the bolt block.
Description of drawings
Accompanying drawing is an embodiment of the present utility model, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A point enlarged view of the present utility model;
Embodiment
See also accompanying drawing 1, accompanying drawing 2.The utility model is made up of inner sleeve 1, trim ring 2, trim ring flange 3, trim ring bolt 4, outer sleeve flange 5, cydariform hydro-expansive rubber filler 6, synthetic rubber filler 7, outer sleeve 8, end ring 9, chek bolt 10, connecting plate 11, guide plate 12, bellows 13, stiffening ring 14, filler baffle ring 15, throat ring 16, end ring stiffening plate 17, bolt block 18 and concora crush hole 19.
