Abstract
The utility model relates to a corrugation compensation device which is not easy to break, comprising a telescopic pipe, a corrugated pipe, a sleeve pipe, a baffle, a positioning rod and a sealing element. The sealing element is composed of filling materials and a plurality of pieces of corrugated spring pieces which become narrow toward the right; the circumference of the telescopic pipe is uniformly provided with a plurality of holes. Positioning nuts and positioning bolts with the same number penetrate the sleeve pipe through screw to extend in corresponding holes on the circumference of the telescopic pipe. The sealing element has relatively good sealing performance and can effectively prevent coal powder leaking to corrugated pipes. The positioning nuts and the positioning bolts extend in the holes on the circumference of the telescopic pipe, which has the functions of limiting the axial displacement of the corrugated pipes and controlling the telescopic pipe to rotate oppositely with the sleeve pipe to cause the corrugated pipes to twist and break.
Description
The utility model relates to the FlexbleJoint that joiner, especially bellows between a kind of coal dust delivery pipe are difficult for breaking.
At present, the structure of known FlexbleJoint is made up of telescopic pipe, bellows, sleeve pipe, baffle plate, positioning rod and Sealing.Wherein Sealing is to adopt wire netting or put the round wire volume between coal dust delivery pipe outer wall and bellows inwall.But use through reality and can't solve the problem of leakage of pulverized coal to the bellows.Because the value that produces the axial line displacement when bellows surpasses wire netting length, then wire netting will rupture, and this moment, coal dust just leaked to the bellows inwall.And the employing steel wire coil because temperature, pressure often change in the coal dust course of conveying, so steel wire coil often is in elastic deformation, arrives to a certain degree, and steel wire will produce fatigue, loses seal action.Thereby make bellows inwall accumulated powder, and cause bellows bursts.Moreover in the coal dust course of conveying,, will damage bellows in case the axial line displacement is excessive because the variation of temperature and pressure can form the axial line displacement of pipeline.And telescopic pipe and sleeve pipe are easily done radially to rotate, and bellows is broken because of distortion produces.
The purpose of this utility model provides the FlexbleJoint that a kind of bellows is difficult for breaking.
The purpose of this utility model is achieved in that a kind of FlexbleJoint comprises telescopic pipe, bellows, sleeve pipe, baffle plate, positioning rod and Sealing, wherein baffle plate is fixed on the telescopic pipe of bellows both sides, positioning rod is fixed by bolt, nut after passing left and right sides baffle plate respectively, the right side baffle plate is provided with a screw, hold-down bolt links to each other by the pressing plate of screw with the baffle plate right side, pressing plate links to each other with Sealing, and described Sealing is made up of the corrugation shape spring sheet that filler and multi-disc narrow down to the right.
Owing to adopt such scheme, can make coal dust in course of conveying, can't leak to the bellows inwall, thereby greatly improve the sealing of Sealing, increased the working life of FlexbleJoint.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
In Fig. 1, baffle plate 7 is fixed on the telescopic pipe 1 of bellows 5 both sides, it is fixing by bolt 2 and nut 3 that positioning rod 4 passes left and right sides baffle plate 7 backs respectively, offer a screw on the right side baffle plate 7, hold-down bolt 6 links to each other by the pressing plate 11 of screw with baffle plate 7 right sides, pressing plate 11 links to each other with Sealing 8, Sealing is made up of filler and 4 corrugation shape spring sheets narrowing down gradually to the right, wherein filler can be rubber graphite asbestos copper wire braiding packing, the material of spring sheet can adopt stainless steel, thickness is 1.5mm, and its width narrows down to the right gradually.When reset condition, filler and spring sheet are to be close to telescopic pipe 1 outer wall, but spring sheet is owing to narrow down gradually to the right, so sleeve pipe 10 inwalls one end just forms certain clearance, when producing the axial line displacement, bellows 5 compresses to the right, driving pressing plate 11 by telescopic pipe 1 moves right and compressible filler, it is tight more that spring sheet and sleeve pipe 10 and telescopic pipe 1 are pressed more, and spring sheet reduces gradually in a splaying of sleeve pipe 10, rebounding force behind the spring sheet pressurized will further compress filler, thereby its seal degree is improved.Owing to adopted 4 flat spring sheets, when axial displacement was S, its decrement had only S/4 concerning filler, so increased the working life of Sealing 8.Then, 8 holes are offered in corresponding part at the eight equal parts of telescopic pipe 1 circumference, on the sleeve pipe 10 with telescopic pipe 1 circumference on the corresponding position in 8 holes offer 8 screws, 8 setscrew nuts, bolt 9 penetrate sleeve pipe 10 by screw and extend on telescopic pipe 1 circumference in the corresponding hole.When setscrew nut, when bolt 9 moves right in the hole, setscrew nut, bolt 9 reduce gradually with the gap in hole, thereby limited the axial line displacement of bellows, and because of gap between square hole and setscrew nut, the bolt 9 less, relatively rotate with sleeve pipe 10 so controlled telescopic pipe 1, thereby prevented that bellows from breaking because of distortion produces.
