Description

TECHNICAL FIELD

[0001] The utility model relates to compensator technical field, concretely is a kind of heat supply pipeline compensator. BACKGROUND

[0002] Pipeline compensator is also called as telescopic device or expansion joint, mainly used to compensate the thermal expansion and cold shrink of pipeline caused by temperature change. If the pipeline cannot expand or shrink freely when temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may cause pipeline rupture and affect normal production. As an important part of pipeline engineering, compensator plays an important role in ensuring the long-term normal operation of pipeline.

[0003] In the process of realizing the utility model, the inventor finds that the following problems in the prior art have not been solved: Although the existing heat supply pipeline compensator is fixed by flange and through bolt, the number of bolts required is large, which is time-consuming and laborious to disassemble and assemble. The corrugated pipe needs to be replaced due to aging during long-term use, which does not meet the use requirements and needs to be improved. Therefore, we propose a heat supply pipeline compensator. UTILITY MODEL CONTENT

[0006] A flange is fixedly installed at the inner end of the heat supply pipeline and both ends of the corrugated pipe, and a sealing ring is placed between every two adjacent flanges;

[0007] Limiting blocks are placed on both sides of the flange, a clamping groove is formed in the limiting block, and the flange is clamped in the clamping groove;

[0008] Limiting cylinders are fixedly installed on both sides of the top and bottom of the limiting block, a screw rod is movably penetrated in the middle of the limiting cylinder, and a nut is rotatably connected to one end of the screw rod by external thread;

[0009] Support blocks are fixedly installed at both ends of the flange, and the support blocks are clamped in the limiting groove preformed in the limiting block. The limiting block, clamping groove and screw rod and other components can be used together. During the use of the compensator, the limiting block can be sleeved on the outer side of the flange, the flange can be extruded to the sealing ring under stress, and the flange is clamped in the clamping groove. At the same time, the support block is inserted into the limiting groove, then the screw rod is penetrated into the limiting cylinder on the same side, and the nut is rotated and screwed. Compared with the existing method, the disassembly and assembly process of the compensator can be simplified, and the compensator is easy to replace in the later period.

[0010] As an optional solution of the technical scheme of the application, the two sides of the limiting block close to the clamping groove are provided with inclined surface parts, the width of the clamping groove is smaller than the maximum width of the two groups of flanges and the sealing ring, and the inclined surface parts and other components are used in cooperation. When the limiting block is sleeved, the limiting block is located at the two ends of the flange, and then the limiting block is extruded. Due to the arrangement of the inclined surface parts, the flange is internally moved under stress to extrude the sealing ring, so that the sleeving of the limiting block is more labor-saving, the practicality is strong, and the use effect is more ideal.

[0011] As an optional solution of the technical scheme of the application, the two groups of limiting blocks are fixedly installed with indicator plates on the front sides, and the indicator plates are fixed by welding. The guiding words on the indicator plates can inform the operators of the corresponding procedures, so that the operators can understand and use conveniently.

[0012] As an optional solution of the technical scheme of the application, the shape of the supporting block is matched with the contour of the limiting groove, so that the clamping component is adaptively designed, and the excessive deviation condition can be prevented to avoid affecting the expansion of the corrugated pipe.

[0013] As an optional solution of the technical scheme of the application, the outer wall of the nut is provided with a hexagonal surface, and the nut can be clamped and rotated on the hexagonal surface by using a wrench, so that the nut can be disassembled conveniently.

[0014] Compared with the prior art, the application has the following beneficial effects:

[0015] 1. The heat supply pipeline compensator is provided with limiting blocks, clamping grooves and screws.
