Abstract
The utility model provides a constraint type corrugated shock absorber which comprises a corrugated pipe, two flanges and a constraint component. The two flanges are respectively mounted at two ends of the corrugated pipe, two ends of the constraint component are respectively connected with the two flanges, and the outer end surface of the constraint component is not higher than sealing surfaces of the two flanges. A connection mode includes that the constraint component is rooted in the circular flanges and internal pressure and thrust constraint effects are realized for a product by the constraint component on the premise that connection surfaces of the flanges are not destroyed. The constraint type corrugated shock absorber has the advantages that the constraint type corrugated shock absorber is provided with the standard flanges and accordingly is convenient to machine, the production cost is reduced, problems of large occupied area of a common corrugated shock absorber and high production cost of special-shaped flanges in the prior art can be solved, and the constraint type corrugated shock absorber has substantive features and advancement.
Description
Technical field
The utility model relates to pipeline flexible link, particularly a kind of ripple vibration damper.
Background technique
Ripple vibration damper claims again expansion joint, slip joint, is the effective dilatation that utilizes corrugated pipe elastic element, absorbs pipeline, conduit or the container a kind of compensation device because of the dimensional changes of a variety of causes generation.In some production occasions, such as oil refinery, to the requirement of ripple vibration damper, be not only to absorb displacement deformation, also require this element can bear the larger additional force and moment being caused by connection device.At present in production reality, the common ripple vibration damper of many employings, namely weld respectively two flanges at the two ends of one section of bellows, this structure, can only absorb displacement deformation, helpless for the additional force and moment being caused by connection device, common way is on pipeline, separately to establish fixed support, this has just not only increased cost of production, also production site has been proposed to requirements at the higher level.Also have a kind of way to be, the flange at bellows two ends is made to Special-shaped flange, design some flanges in the outside of original flange, and drag link mechanism is set on flange flange, two flanges are linked together.This structure, by the pulling force of drag link mechanism, is pressed the selfdiscipline of thrust in realizing, outwards do not transmit, thereby reach the function that absorbs additional force and moment.But in this structure, Special-shaped flange is not standard piece, cost of production is higher, is unfavorable for batch production.
Model utility content
The utility model proposes a kind of restricted type ripple vibration damper, solve in prior art, common ripple vibration damper takes up an area the problem large, Special-shaped flange cost of production is high.
The technical solution of the utility model is achieved in that a kind of restricted type ripple vibration damper, comprise bellows and two flanges, described two flanges are installed on respectively bellows two ends, also comprise confining part, described confining part two ends are connected with described two flanges respectively, and described confining part exterior edge face is not higher than the sealing surface of described two flanges.This Placement be in circular flange body for confining part is taken root, under the prerequisite of not destroying flange connection surface, realize confining part and press in to product the effect of contraction of thrust.Standard flange due to what adopt, therefore easy to process, reduce cost of production.
Described confining part two ends are threaded, and are connected with described two flanges respectively by screw thread.Confining part can be several threaded stems, and two described flanges are linked together, and threaded stem is easy to process, connects reliable, with low cost.
Described confining part two ends adopt taper counterbore mode, are connected respectively with described two flanges.Taper counterbore mode linkage structure is simple, connects reliable.
Described confining part two ends adopt cylindricality counterbore mode, are connected respectively with described two flanges.It is another kind of simple and reliable Placement that cylindricality counterbore mode connects.
The utility model is installed confining part dexterously on standard flange part, neither affecting flange installs, can realize again the selfdiscipline of interior pressure thrust, outwards do not transmit, thereby reach the function that absorbs additional force and moment, and simple in structure, connect reliable, be applicable to standardization batch production, reduced cost of production, will there is substantive distinguishing features and progress.
