Abstract
The invention provides a bellow expansion joint. The bellow expansion joint comprises an adapter tube (1), a corrugated tube (2), a stud (3), a nut (4), a middle adapter tube (5), an annular plate (6) and a limiting nut (7), and is characterized in that the outer surface of the adapter tube (1) is connected with the corrugated tube (2); the stud (3) is arranged beside the corrugated tube (2); the nut (4) is arranged on the stud (3); the right end of the adapter tube (1) is connected with the middle adapter tube (5); the annular plate (6) is arranged at the right end of the middle adapter tube (5); the limiting nut (7) is arranged on the stud (3). The bellow expansion joint has the advantages of convenience in installation and maintenance, easiness in hoisting and long service life.
Description
Technical field
The present invention relates to a kind of expansion joint, relate in particular to a kind of corrugated expansion joint.
Background technique
Because boiler of power plant pulverized coal channel is continued to use material filling type compensator and is produced coal dust and reveal, and at temperature the aging constrained displacement of filler matter, pipe-line system is expanded not smooth, the normal operation of impact management road system.
Based on above-mentioned shortcoming, can adopt the corrugated expansion joint of secondary seal according to pulverized coal channel working condition, realize the new demand of short mounting distance large compensation.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of have convenient for installation and maintenance, lifting is simple, the corrugated expansion joint of the advantage of long service life.
For solving the problems of the technologies described above, the invention provides a kind of corrugated expansion joint, comprise adapter, bellows, double-screw bolt, nut, middle adapter, ring flat-plate, stop nut, it is characterized in that, on described adapter outer surface, be connected with bellows, described bellows side is provided with double-screw bolt, on described double-screw bolt, be provided with nut, described adapter right-hand member is connected with middle adapter, and described middle adapter right-hand member is provided with ring flat-plate, is also provided with stop nut on described double-screw bolt.
Further, described bellows has two, is separately positioned on the two ends, left and right of adapter.
Further, described double-screw bolt is stud.
Further, described double-screw bolt has four.
Further, described nut has 16.
Further, described stop nut has 8.
Further, described support adopts insulating material to make.
The beneficial effect that the present invention brings is:
That corrugated expansion joint of the present invention has advantages of is convenient for installation and maintenance, lifting simple, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1-adapter, 2-bellows, 3-double-screw bolt, 4-nut
5-middle adapter, 6-ring flat-plate, 7-stop nut.
Embodiment
Below to by reference to the accompanying drawings preferred embodiment of the present invention being elaborated, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, a kind of corrugated expansion joint, comprise and take over 1, bellows 2, double-screw bolt 3, nut 4, middle adapter 5, ring flat-plate 6, stop nut 7, on described adapter 1 outer surface, be connected with bellows 2, described bellows 2 sides are provided with double-screw bolt 3, on described double-screw bolt 3, be provided with nut 4, described adapter 1 right-hand member is connected with middle adapter 5, described middle adapter 5 right-hand members are provided with ring flat-plate 6, on described double-screw bolt 3, be also provided with stop nut 7, described bellows 2 has two, be separately positioned on the two ends, left and right of taking over 1, described double-screw bolt 3 is stud, described double-screw bolt 3 has four, described nut 4 has 16, described ring flat-plate 6 has four, described stop nut 7 has 8.
In sum, corrugated expansion joint of the present invention have advantages of convenient for installation and maintenance, lifting is simple, long service life.
The above; it is only one of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
