Abstract
The utility model discloses a compensator with full-flexibility corrugated tubes. The compensator comprises flanges with tubes. The flanges with the tubes are arranged at two ends of the compensator. The compensator is characterized in that the bidirectional wave omega-shaped corrugated tubes are connected between the flanges with the tubes, and cracking barreled flexible hinges are arranged among the outer sides of the bidirectional wave omega-shaped corrugated tubes and the flanges with the tubes. The compensator has the advantages that the cracking barreled flexible hinges mainly comprise elliptical compound flexible hinges with straight beams, can bearing axial tension and compression while bending and torsional deformation can be compensated, and the compensator is of a novel flexible connection and transmission structure, structurally discontinuous zones are subjected to smooth transition, and accordingly stress concentration can be effectively reduced; influence of high-pressure air on measurement results of balance scales can be effectively eliminated, and accordingly the precision of a thrust vector testing system can be obviously improved.
Description
Technical field
The utility model belongs to pipe line compensating device field, specifically, relates to a kind of full flexible bellow compensator.
Background technique
Corrugated expansion joint is the critical component of air bridges, mainly formed by internal layer stretching/compressing and little U-shaped bellows and the outer barrel property flexible hinge that splits being formed by straight beam type flexible hinge of flexural rigidity, and be the structural type that current flexible separating system generally adopts.Because the stretching/compressing rigidity of bellows is little, under High Pressure, larger stretching/compressing distortion will be produced, directly act on highi degree of accuracy force balance, the validity that impact is measured, therefore adopt outer slabbing bucket flexible hinge encapsulate inner layer bellows, reduce bellows stretching/compressing distortion under pressure.This air bridges can reduce additional force and moment when high-pressure air flows in steam line, balance being produced to a certain extent, thereby improves the precision of thrust vector measuring system.
The internal layer bellows of corrugated expansion joint is unidirectional ripple bellows, can compensate stretching/compressing distortion and bending deflection, but because it is axially having ripple, therefore there are the following problems:
(1) circumferencial direction (laterally) is flexible not enough, can not effective compensation torsional deflection;
(2) while work under the large load-up conditions such as ultrahigh pressure, easily unstability.
The outer slabbing bucket flexible hinge of corrugated expansion joint is mainly made up of straight beam type flexible hinge, exists stress to concentrate at structure locus of discontinuity, causes this position strength deficiency, affects the raising of air bridges and even thrust vector measuring system precision.
Indulge the above, the air bridges being made up of this type corrugated expansion joint can not effectively be eliminated the impact of high-pressure air on balance measurement result, can not significantly improve the precision of thrust vector measuring system.
Model utility content
In order to address the above problem, the utility model provides a kind of full flexible bellow compensator, can effectively eliminate the impact of high-pressure air on balance measurement result, have and can compensate stretching/compressing, bending and torsion distortion, and the high full flexible bellow compensator of intensity.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of full flexible bellow compensator, comprise the band pipe flange that is arranged on two ends, it is characterized in that: between described band pipe flange, be connected with two-way ripple Ω shape bellows, and be provided with and split a barrel property flexible hinge between the outside of two-way ripple Ω shape bellows and band pipe flange.
As a kind of technological scheme of optimization, described in split barrel property flexible hinge and made by some oval straight beam composite-type flexible hinges.
As a kind of technological scheme of optimization, described two-way ripple Ω shape bellows has ripple at axial and horizontal both direction, axially has Ω shape ripple, and laterally has U-shaped ripple.
As a kind of technological scheme of optimization, described two-way ripple Ω shape bellows and split barrel property flexible hinge and band is provided with connecting sheet between pipe flange, and connecting sheet is provided with seal ring with being with between pipe flange.
As a kind of technological scheme of optimization, the described outboard end with pipe flange is provided with inner ring bolt and outer ring bolt.
Owing to having adopted technique scheme, compared with prior art, the two-way ripple Ω shape bellows the utility model proposes has ripple at axial and horizontal both direction, axially has Ω shape ripple, and laterally has U-shaped ripple.The utlity model has following advantage:
(1) except axially having ripple, circumferencial direction also has ripple, therefore can compensate preferably stretching/compressing, bending and torsion distortion.
(2) due to the existence of transverse wave, the ripple root of axial ripple is had to invigoration effect, and displacement between can balancing axial ripple adjacent corrugations, this New corrugated pipe unstability therefore can effectively be avoided.
The novel barrel property flexible hinge that splits the utility model proposes is mainly made up of oval straight beam composite-type flexible hinge, it is compensated bend and torsional deflection in bearing axial push-pull, a kind of novel flexibly connecting and drive mechanism, owing to having carried out smooth transition at structure locus of discontinuity, therefore can effectively reduce stress concentrates, meanwhile, the utility model can effectively be eliminated the impact of high-pressure air on balance measurement result, thereby significantly improves the precision of thrust vector measuring system.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Brief description of the drawings
