Abstract
The utility model provides a kind of labyrinth type compensator, it include: that inner sleeve pipe flange, the first sealing ring, bellows, support frame and the second sealing ring, the first sealing ring and the bellows are set between inner sleeve pipe flange and support frame and are fixed by chain connecting bolt, the holding tank for the second sealing ring transverse shifting is equipped in one end of the first sealing ring, labyrinth seal tooth that at least 2 groups or more positions mutually stagger is equipped in this FlexbleJoint, the advantages that the utility model long service life, anticorrosion effect are good.
Description
Technical field
The utility model relates to compensation of pipeline apparatus field, especially a kind of labyrinth type compensator.
Background technique
Compensator is traditionally also expansion joint or telescopic joint, by bellows (a kind of elasticity member for constituting its operative body
Part) and the attachmentes composition such as end pipe, bracket, flange, conduit, it being used primarily in various pipelines, it can compensate for the thermal walking of pipeline,
Mechanically deform and the various mechanical oscillation of absorption are played the role of reducing pipe deforming stress and improve pipeline service life.
Compensator be to the elastic element using compensator effective dilatation come absorption line, conduit or container by
The reasons such as expand with heat and contract with cold and a kind of compensation device of change in size generated, belong to a kind of compensating element, can to axial direction, laterally,
With the absorption of angular displacement.
Manufacturing enterprise finds compensator failure cause analysis, with lengthening during operation, the elastic component of compensator
Corrosion be mainly failure mode, corrosion of the compensator by high-temperature medium, it is easy to because corrosion causes production to suspend, cause
Economic loss.
Summary of the invention
(1) the technical issues of solving
The utility model is insufficient according to prior art, and provides a kind of labyrinth type compensator, makes corrosion resistance more
It is good, improve the purpose of compensator service life.
(2) technical solution
In view of the deficiencies of the prior art, the utility model provides a kind of labyrinth type compensator, comprising: inner sleeve pipe flange,
First sealing ring, bellows, support frame and the second sealing ring, first sealing ring and the bellows are set to the inner sleeve
It is fixed between pipe flange and support frame as described above and by chain connecting bolt, is equipped in one end of first sealing ring and supplies described second
It is close to be equipped with the labyrinth that at least 2 groups or more positions mutually stagger in this FlexbleJoint for the holding tank of sealing ring transverse shifting
Seal tooth.
Further, the material of first sealing ring is rubber.
Further, the material of second sealing ring is metal.
(3) beneficial effect
Compared with the existing technology, the utility model have it is following the utility model has the advantages that
1. the prior art be by oneself characteristic of bellows material serve it is corrosion-resistant, but because high pressure gas containing corrode
Property, so the anti-corrosion effects of itself are poor, and the utility model is to lean on labyrinth sealing, even if outermost layer first corrodes, behind
There are also several pipe protection layers, the effect for extending physical life is played.
2. there is a small amount of gas to pass through labyrinth sealing area in order to prevent, in labyrinth sealing area, outer layer also passes through the first sealing
In the case that ring is matched with the second sealing ring, thoroughly prevent the chance of etchant gas contact bellows.
The advantages that the utility model long service life, anticorrosion effect are good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of the utility model.
Fig. 3 is the usage state diagram of the utility model.
In figure: 1- inner sleeve pipe flange, the first sealing ring of 2-, 3- bellows, 4- support frame, 5- regulating device, 6- connection spiral shell
Bolt, the second sealing ring of 7-, 8- labyrinth seal tooth, 9- pipe flange.
Specific embodiment
Below in conjunction with the attached drawing in the embodiments of the present invention, to the technical solution in the embodiments of the present invention
It is clearly and completely described, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment one:
A kind of corrosion-resistant FlexbleJoint as shown in Figure 1:, comprising: inner sleeve pipe flange 1, the first sealing ring 2, bellows 3,
Support frame 4 and the second sealing ring 7, the first sealing ring 2 and bellows 3 are set between inner sleeve pipe flange 1 and support frame 4 and pass through
Chain connecting bolt 6 is fixed, and the labyrinth seal tooth 8 that at least 2 groups or more positions mutually stagger is equipped in this FlexbleJoint.
It is as shown in Figure 2: to be equipped with the holding tank for 7 transverse shifting of the second sealing ring in one end of the first sealing ring 2, first is close
The material of seal ring 2 is rubber, and the material of the second sealing ring 7 is metal.
As shown in Figure 3: arrow direction is gas flow direction in figure, because labyrinth sealing has easily manufactured, maintenance
The features such as being easy, is widely adopted, compensator is communicated by pipe flange 9 with the pipeline at both ends, and compensator is in regulating device 5
Under effect, a certain range of nose balance is made, has a small amount of etchant gas to overflow across labyrinth seal area in order to prevent, in labyrinth seal
Area is externally provided with the protecting wall that the first sealing ring 2 is matched with the second sealing ring 7, because the corrosion resistance of rubber material is poor, institute
To be used to stop a small amount of etchant gas.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
