Description
Technical field
The utility model is related to bellows expansion joint fields, more particularly to a kind of catalytic gasoline adsorpting desulfurization device that is used for inhale
The expansion joint of attached pipeline.
Background technology
Catalytic gasoline adsorpting desulfurization device is also referred to as S-Zorb, and production can be lost with lower octane number in 10ppm or less
Low-sulphur oil.For its adsorbent pipeline due to flow velocity height, medium is graininess, and pipeline abrasion is very serious.Conventional expansion joint
Due to guide shell, circulation area can reduce, especially in this small-caliber pipeline of S-Zorb device catalyst lines,
Circulation area reduces can clearly, and medium can be sharply increased in expansion segment flow velocity, cause guide shell to be easily worn, in turn
Expansion joint is caused to fail.
Utility model content
The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides a kind of for catalytic gasoline absorption desulfurization
Device adsorbs the expansion joint of pipeline, can adsorb in catalytic gasoline adsorpting desulfurization device and be run steadily in the long term on pipeline, be avoided
Expansion joint fails.
Technical solution used by the utility model is as follows：
A kind of expansion joint for catalytic gasoline adsorpting desulfurization device absorption pipeline, including inlet flange, the entrance method
Orchid is connected by the side of the first work bellows and first end plate, in the other side arranged for interval second end of the first end plate
One end of plate, the setting balance bellows between the first end plate and the second end plate, the balance bellows is flat by first
Weighing apparatus wave is taken over to be connect with the other side of first end plate, and the other end of the balance bellows is taken over and second by the second balance wave
The side of end plate connects, and the other side of second end plate passes through the second work bellows connection outlet flange；It further include one
It takes over, the one end taken over is welded with inlet flange, and the other end sequence taken over is through the first work bellows, first end
Plate, the first balance wave are taken over, balance bellows, the second balance wave is taken over, the second end plate, second work bellows and with outlet method
The splicing position of blue inside grafting, the second work bellows and outlet(discharge) flange is equipped with gap.
Its further technical solution is：
It is opened up on the inside of the outlet(discharge) flange for coordinating the groove taken over；
In on the inlet flange, first end plate and the second end plate through a piece pull rod of installation, in the first end plate, the
Two end plates and outlet(discharge) flange also extend through a piece pull rod of installation, and the both ends of each pull rod are fixed by nut check.
The beneficial effects of the utility model are as follows：
The utility model is simple in structure, easy to use, the present invention by will take over replace guide shell, can reduce vibration with
Prevent medium from washing away bellows, the replacement of guide shell can reduce to avoid previous circulation area keeps expansion joint segment flow velocity increased
Problem, and there is no guide shell abrasion and expansion joint fail the problem of, substantially increase the service life of expansion joint, make this practicality
Novel operation that can be steady in a long-term.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein：1, inlet flange；2, the first work bellows；3, it takes over；4, nut；5, first end plate；6, the first balance
Wave is taken over；7, bellows is balanced；8, the second balance wave is taken over；9, the second end plate；10, pull rod；11, the second work bellows；12、

Specific implementation mode
Illustrate specific embodiment of the present utility model below.
As shown in Figure 1, a kind of expansion joint for catalytic gasoline adsorpting desulfurization device absorption pipeline includes inlet flange 1,
Inlet flange 1 is connect by the first work bellows 2 with the side of first end plate 5, in the other side arranged for interval of first end plate 5
Second end plate 9, the setting balance bellows 7 between first end plate 5 and the second end plate 9, one end of balance bellows 7 passes through first
Balance wave take over 6 connect with the other side of first end plate 5, and the other end for balancing bellows 7 passes through the second balance wave take over 8 and the
The side of two end plates 9 connects, and the other side of the second end plate 9 passes through the second work 11 connection outlet flange 12 of bellows；Further include
One piece-root grafting pipe 3, one end of take over 3 are welded with inlet flange 1, and the other end sequence of take over 3 is through the first work bellows 2, the
End plate 5, the first balance wave take over 6, balance bellows 7, the second balance wave take over 8, the second end plate 9, second work bellows
11 and with the inside grafting of outlet(discharge) flange 12, open up the groove for coordinating take over 3 in the inside of outlet(discharge) flange 12, the second work
The splicing position of bellows 11 and outlet(discharge) flange 12 is equipped with gap, which is expansion joint dilatation joint, the size of dilatation joint with it is swollen
Swollen section axial design displacement is consistent, and when line temperature rises to design temperature, dilatation joint becomes 0, at this time the circulation of expansion joint
Can be consistent with pipeline, by dilatation joint at setting one, medium flow direction fluctuation can be effectively reduced.
