Description

Technical Field

[0001] The utility model relates to a sleeve compensator. Background Art

[0002] The sleeve compensator is connected in series in a pipeline to compensate for the thermal expansion and contraction of the pipeline. The common connection method between the sleeve compensator and the pipeline is as follows: the pipeline is disconnected, one end of the sleeve compensator is welded to a cross-section of the pipeline, and the other end of the sleeve compensator is welded to another cross-section of the pipeline. The length cut off from the pipeline must be equal to the length of the sleeve compensator. Otherwise, it is difficult for the sleeve compensator to be butted with the pipeline, and the pipeline needs to be cut or repaired by welding again or multiple times. In addition, when the sleeve compensator needs to be repaired, it needs to be cut off from the pipeline, and after being repaired, the sleeve compensator is welded on again. The disassembly and assembly between the sleeve compensator and the pipeline are not convenient. Summary of the Utility Model

[0003] In order to facilitate the disassembly and assembly with the pipeline, the utility model provides a sleeve compensator with convenient disassembly and assembly.

[0004] The technical solution of the utility model is a sleeve compensator with convenient disassembly and assembly, which includes an outer pipe 5, an inner pipe 7 is inserted into the outer pipe, a sealing filler 6 is arranged between the outer pipe and the inner pipe, and the sealing filler is pressed by a gland 4. The feature is that a left flange 2 is hermetically welded at the left end of the inner pipe 7, a right flange 10 is hermetically welded at the right end of the outer pipe, and a plurality of tie rods 1 are symmetrically connected between the left flange and the right flange. The tie rods pass through the left flange and the right flange, and both ends of the tie rods have threads, and nuts 3 are screwed on the threads. The nuts are located on both sides of the left flange, and the nuts are also located on both sides of the right flange.

[0005] The beneficial effect of the utility model is that the sleeve compensator with convenient disassembly and assembly is convenient for disassembly and assembly with the pipeline, and the sleeve compensator itself is also convenient for loading and unloading. Brief Description of the Drawings

[0006] Figure 1 It is a schematic structural view of the utility model.

[0007] Figure 2 For Figure 1 the left view, the tie rods are not drawn in this figure.

[0008] Reference signs in the drawings: 1 - tie rod, 2 - left flange, 3 - nut, 4 - gland, 5 - outer pipe, 6 - sealing filler, 7 - inner pipe, 8 - small-diameter pipe, 9 - ear plate, 10 - right flange, 11 - through hole, 12 - tie rod hole. Detailed Description of the Invention

[0009] A sleeve compensator with convenient disassembly and assembly, which comprises an outer pipe 5, an inner pipe 7 is inserted into the outer pipe, a sealing packing 6 is arranged between the outer pipe and the inner pipe, and the sealing packing is pressed by a gland 4. The characteristics are that a left flange 2 is hermetically welded at the left end of the inner pipe 7, a right flange 10 is hermetically welded on a small-diameter pipe 8 which is contracted at the right part of the outer pipe, a plurality of through holes 11 are arranged on the left flange and the right flange, and the through holes are used for allowing bolts to pass through and be connected with a pipeline. A plurality of tie rods 1 are symmetrically connected between the left flange and the right flange. The tie rods pass through the left flange and the right flange. Both ends of the tie rods respectively have threads, and nuts 3 are screwed on the threads. The nuts are located on both sides of the left flange and the nuts are located on both sides of the right flange.

[0010] The tie rods can be located at the circumferences of the left flange and the right flange, but in this case, the outer diameters of the left flange and the right flange need to be increased. In order to reduce the material consumption of the left flange and the right flange, a plurality of ear plates 9 are symmetrically welded at the circumferences of the left flange and the right flange, and tie rod holes 12 for allowing the tie rods to pass through are arranged on the ear plates.

[0011] The characteristic of the sleeve compensator with convenient disassembly and assembly is that the left flange and the right flange of the sleeve compensator with convenient disassembly and assembly are connected with the pipeline through bolts. When connecting, if the cut length of the pipeline is greater than or less than the length of the sleeve compensator with convenient disassembly and assembly, the nuts on the tie rods can be adjusted to make the length of the sleeve compensator with convenient disassembly and assembly match the cut length of the pipeline, and the connection between the sleeve compensator with convenient disassembly and assembly and the pipeline is convenient;

[0012] When the sleeve compensator with convenient disassembly and assembly needs to be maintained or repaired, the bolts of the left flange and the right flange can be removed and the sleeve compensator can be taken out;

[0013] When the sleeve compensator with convenient disassembly and assembly needs to be disassembled, the nuts on the adjustable tie rods can be adjusted to make the inner pipe withdraw from the sealing packing. It should be noted that due to the large friction force between the inner pipe and the sealing packing, it is difficult to pull out the inner pipe by hand; similarly, inserting the inner pipe into the sealing packing can also be completed by adjusting the nuts on the tie rods. Sleeve compensator

[0014] Before the sleeve compensator with convenient disassembly and assembly operates, the tie rods should be removed.
