Description
Technical field
The utility model belongs to pressure pipeline scope, in particular to a kind of tetrafluoro corrugated expansion joint.
Background technique
In order to guarantee the stabilization and safety of pipeline in hot state, reduce pipeline and expand with heat and contract with cold the stress of generation, on pipeline
Hold-down support and compensation device should be installed at a certain distance.Previous common compensation method is using square-shaped joints.Though it
So manufacture simplicity, reliable operation, but very large space need to be occupied, especially for the pipeline often inconvenient use of major diameter.Sleeve
Compensator is easily leaked, need to periodically be overhauled since it uses packing seal structure.
The application form of compensator is versatile and flexible, and the size of original collocation structure is made to contract significantly using the flexibility of compensator
It is small, it is allowed to suitable for the pipeline of Large Diameter Pipeline.Compared with the compensation method of axialmode compensator, such design can be made full use of
The natural conditions of various turnings in piping keep the compensation design of piping more effective, reliable and economical.The structure of FlexbleJoint
Bellows is generally comprised, adapter tube is respectively welded at the both ends of bellows, is welded with flange on adapter tube；By flange and pipe when use
Road connection, with compensate pipeline expand with heat and contract with cold or the vibration of pipeline.This FlexbleJoint during installation has the length of pipeline
Required precision needs repeatedly to carry out cutting to the length of pipeline just to can guarantee its required precision, so that installation is non-in erecting bed
It is often inconvenient.
It is flexible member using bellows as core to corrugated expansion joint, is remake on pipeline axial, laterally and angular
The compensation in three directions.Axialmode compensator is in order to reduce the self-excitation phenomena of medium.There is no inner sleeve in interiors of products, very big
Limit radial compensation ability in degree, thus it is general only to absorb or compensate the axial displacement of pipeline: lateral displacement compensator
The main lateral displacement absorbed perpendicular to compensator axis, lower link bar lateral displacement compensator are suitable for absorbing lateral displacement,
The combination of axial, angular and any three directions displacement can be absorbed.
Tetrafluoro corrugated expansion joint not only acts as length in pipe-line system by being bonded tetrafluoro liner in ripple inside pipe wall
Degree, temperature, position and angle compensation effect, and there is antisepsis.Tetrafluoro corrugated expansion joint is used for strong corrosive media
Pipe-line system in compensate the displacement and installation deviation expanded with heat and contract with cold, reduce the vibration of pipe-line system.This tetrafluoro bellows is mended
Repay device have the defects that in use it is certain: when being applied to has the pipe-line system of negative pressure, the negative pressure in pipeline may make
Tetrafluoro liner is deformed；On the other hand, bellows is thin-wall part, easily deformable, poor rigidity, either internal pressure, still
External pressure may be such that bellows deforms, and the normal use of lining tetrafluoro corrugated expansion joint is influenced under both of these case.
Utility model content
Of the existing technology in order to solve the problems, such as, the utility model provides a kind of tetrafluoro corrugated expansion joint, guarantees
The features such as normal use of tetrafluoro expansion joint securely and reliably has compensation performance good, and structure is simple, and performance is stablized, overcomes
The defect of conventional compensation device improves the service life of compensator.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of tetrafluoro bellows

Pressure-bearing ball is circumferentially arranged in ball, the hoop, and the pressure-bearing ball layout is in the bottom of tetrafluoro bellows inboard wall groove.
Preferably, the hoop includes ring and retainer ring, the retainer ring is uniformly arranged on the excircle of ring, the card
Pressure-bearing ball is provided in circle.
Preferably, tow sides are equipped with annular groove to the ring in the axial direction.
Preferably, the tetrafluoro bellows inboard wall groove opening is symmetrically arranged with upper stopper and lower stopper, the upper gear
Block and lower stopper are contradicted with hoop inner ring.
Preferably, the clear distance between the upper stopper and lower stopper is less than 1~8mm of hoop thickness.
Preferably, the hoop is made of corrosion resistant rubber.
Preferably, the pressure-bearing ball is from inside to outside successively by solid rubber ball, elastic metallic net and tetrafluoro surface layer
Composition.
Preferably, the tetrafluoro ripple tube outer surface is provided with metal bellows outer cover.
Preferably, the tetrafluoro bellows two-port is all covered with fixing collar.
The utility model has the following beneficial effects: the inner wall annular groove for the tetrafluoro lining that the utility model is wrapped up in metal bellows
Interior setting pressure-bearing ball ensure that tetrafluoro lining is also unlikely to deform under compensation rate and positive/negative-pressure effect, while ensure that compensator
Local overcompensation will not be brought, product service life is extended；Interiors of products hoop structure economy is obvious, and use pair
Claim block to press, ensures the reliability that product uses；Rationally, performance safety is reliable, simple installation for the design of this compensator structure
It is convenient, have the advantages that high compensation, corrosion-resistant, receiving high pressure.
