Abstract
The utility model provides a corrugated expansion joint which comprises a corrugated expansion joint body. A side plate is arranged on each of two sides of the corrugated expansion joint body, a labyrinth-type sealing plate is arranged on the two side plates, width of the labyrinth-type sealing plate is smaller than an interval between the side plates, a heat-insulating layer is arranged on the outer side of the labyrinth-type sealing plate in a covering manner, a flexible sealing plate is fixedly arranged outside the heat-insulating layer through a flange, and width of the flexible sealing plate is larger than the interval of the side plates. By the corrugated expansion joint, when an original corrugated expansion joint is damaged, under the circumstance that the original corrugated expansion joint is not replaced, sealability and flexibility of the original expansion joint are guaranteed, difficulty in replacing is avoided, service life of the corrugated expansion joint is longer than that of a replaced expansion joint, and a lot of maintenance cost is saved.
Description
Technical field
The utility model relates to a kind of corrugated expansion joint, refers to that cement plant medium is the corrugated expansion joint of gas or high-temperature gas.
Background technique
The rotary system in cement plant is with there being a large amount of corrugated expansion joints, and in the process of using, after corrugated expansion joint damages, the way of processing is exactly often to change.The corrugated expansion joint size of using due to cement plant is all larger, and diameter reaches more than 3 meters, and have be arranged on the position that highly reaches hundred meters, actual change very difficult.
Summary of the invention
Technical problem to be solved in the utility model is how when corrugated expansion joint damages, and does not change corrugated expansion joint and just can make it continue to use, thereby solved corrugated expansion joint, changes difficulty and the high problem of maintenance expenses.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of corrugated expansion joint, comprise corrugated expansion joint, side plate is respectively established in both sides at corrugated expansion joint, on biside plate, establish labyrinth plate, the width of labyrinth plate is less than the spacing of biside plate, in labyrinth plate outside, covers thermal insulation layer, outside thermal insulation layer, by flange, set firmly flexible sealing plate, the width of flexible sealing plate is greater than the spacing of biside plate.
In order further to guarantee the tightness of expansion joint, guarantee the fully compacting of flexible sealing plate, at flexible sealing plate, add a pressing plate outward.
The utility model adopts the designed corrugated expansion joint of technique scheme, because side plate is respectively established in the both sides at corrugated expansion joint, on biside plate, establish labyrinth plate, in labyrinth plate outside, cover thermal insulation layer, outside thermal insulation layer, by flange, set firmly flexible sealing plate, like this, when former corrugated expansion joint damages, in the situation that not changing former corrugated expansion joint, both sealing and the stretchability of original corrugated expansion joint had been guaranteed, avoid again the difficulty of replacing, and than the expansion joint longer service life of changing, also saved a large amount of maintenance expensess simultaneously.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the utility model pipe expansion joint;
Fig. 2 represents the structural representation of the utility model square tube expansion joint.
Embodiment
Below in conjunction with accompanying drawing, the structure of a kind of corrugated expansion joint of the utility model is done to concrete invention.
Referring to Fig. 1, Fig. 2, the structure of a kind of corrugated expansion joint of the utility model comprises the corrugated expansion joint 1 on pipeline 14, side plate is respectively established in both sides at corrugated expansion joint 1, left sideboard 2 as shown in FIG. and right sideboard 13, between left sideboard 2 and right sideboard 13 biside plates, from inside to outside weld successively left labyrinth plate 3 and right labyrinth plate 12, the width of left labyrinth plate 3 and right labyrinth plate 12 is less than the spacing of left sideboard 2 and right sideboard 13 biside plates, to guarantee the stretchability of expansion joint.Outside at left labyrinth plate 3 and right labyrinth plate 12 covers thermal insulation layer 4, if medium temperature is high, thermal insulation layer 4 can be used fire-retardent fiber felt-rug, if medium temperature is low, thermal insulation layer 4 can be with rock wool etc., to ensure original heat-insulation and heat-preservation function.Outside at thermal insulation layer 4 sets firmly flexible sealing plate 7 by flange 5, bolt 8, plain cushion 9, bullet pad 10, nut 11, if medium temperature is high, flexible sealing plate 7 can be used carbon tantnickel composite sheet, if medium temperature is low, flexible sealing plate 7 can be used rubber plate, the width of flexible sealing plate 7 is greater than the spacing of left sideboard 2 and right sideboard 13 biside plates, and object is in order to guarantee the stretchability of corrugated expansion joint 1.In order further to protect the tightness of corrugated expansion joint 1, guarantee fully compacting of flexible sealing plate 7, outside flexible sealing plate 7, add again a pressing plate 6.
Claims (2)
1. a corrugated expansion joint, comprise corrugated expansion joint, it is characterized in that respectively establishing side plate in the both sides of corrugated expansion joint, on biside plate, establish labyrinth plate, the width of labyrinth plate is less than the spacing of biside plate, in labyrinth plate outside, cover thermal insulation layer, outside thermal insulation layer, by flange, set firmly flexible sealing plate, the width of flexible sealing plate is greater than the spacing of biside plate.
2. corrugated expansion joint according to claim 1, is characterized in that adding a pressing plate outward at flexible sealing plate.
