Abstract
The invention discloses an anti-torsion corrugated compensator which comprises a working connection pipe I and is characterized in that the working connection pipe I is connected with a metal corrugated pipe through a corrugated pipe backing ring. The two ends of the metal corrugated pipe are connected with the corrugated pipe backing ring and a backing ring respectively, compression rings are arranged at the two ends of the metal corrugated pipe respectively in a sleeved mode, and a working connection pipe II and the corrugated pipe backing ring form a closed space. An outer protection cover is located above the metal corrugated pipe, the two ends of the outer protection cover are welded to a transition ring plate II and a transition ring plate I respectively, and the other end of the transition ring plate II is welded to the working connection pipe II. The other end of the transition ring plate I is welded to the corrugated pipe backing ring, a guide ring is installed in the working connection pipe I, the guide ring, a cover plate and the corrugated pipe backing ring are welded, guide fixing blocks are welded to the pipe wall of the working connection pipe I, and the guide ring and the corrugated pipe backing ring are connected through a seal cover plate. The anti-torsion corrugated compensator has the advantages of being convenient to install, safe, reliable, long in service life and more adaptive to changes of a pipeline torsion deformation environment.
Description
Technical field
The present invention relates to a kind of metal corrugated expension joint, particularly a kind of anti-torsion FlexbleJoint.
Background technique
Metal corrugated pipe expansion joint is widely used in the important industries of national economy such as electric power, metallurgy, chemical industry, building, food, pharmacy, the displacement with compensation conduit system because expanding with heat and contract with cold and producing.External Pressure Type compensator is generally applied to city thermal or steam pipe system, for absorption tube bobbin to compensation rate.At present existing External Pressure Type compensator,, anchor block shorter at pipeline firmly can complete the compensation needs of pipeline in situation completely, and safe and reliable, but in, the insecure situation of anchor block long at pipeline, the pipeline distortion that can twist, in the situation that deforming, pipeline can drive the compensator distortion that twists, directly cause the wavy metal torsional deflection of compensator, may cause bellows to tear with the argon-arc welding seam that adapter is connected, cause decline the fatigue life of compensator, even can not re-use.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of safe and reliable, anti-torsion FlexbleJoint that long service life has anti-torsion effect is provided.
Technical solution of the present invention is: anti-torsion FlexbleJoint comprises work adapter (I), bellows gasket ring (I), ring flat-plate, metal bellows, bellows gasket ring (II), outer shield, (II) taken in work, guide shell, it is characterized in that: work is taken between (I) and metal bellows and is connected with bellows gasket ring, the gap that bellows gasket ring (I) and work are taken between (I) is 2～4mm, metal bellows two ends connect respectively bellows gasket ring, airtight space of work adapter (II) and bellows gasket ring composition, outer shield is positioned at the top of metal bellows, two ends are welded on respectively transition ring flat-plate (II), on transition ring flat-plate (I), the other end of transition ring flat-plate (II) is taken over (II) welding with work, transition ring flat-plate (I) the other end and bellows are taken over (I) welding, guide ring threading work is taken over to (I), then guide ring, sealed cover, bellows gasket ring three welding, in guide ring, open rectangular slot (by design size fluting), with welding manner, guide fixed block being welded on to work takes on (I) tube wall, finally use cover plate for sealing opening slot, transportation protection rod assembly is connected in work and takes between (I) and guide ring.
Adopt above technological scheme, in the present invention, adopt guide ring, cover plate, sealed cover, can better play leading role to metal bellows, make bellows realize axial displacement along axial direction, in addition in guide ring, open rectangular groove, square guide fixed block is welded on to work to be taken on wall, cross torsion that more can further spacing bellows, the variation of better adaptation condition environment (pipeline torsional deflection).
Advantageous effect of the present invention is: easy for installation, safe and reliable, and long service life and more adapt to the variation of pipeline torsional deflection environment.
