Description
TECHNICAL FIELD
[0001] The utility model relates to the field of heat supply pipeline compensator, especially a heat supply pipeline compensator. BACKGROUND
[0002] Pipeline compensator is also called telescopic device or expansion joint, and is mainly used for compensating thermal expansion and cold shrinkage of pipeline caused by temperature change. If the pipeline cannot expand or shrink freely when the temperature changes, thermal stress will be generated in the pipeline. As an important part of pipeline engineering, the compensator plays an important role in ensuring the long-term normal operation of the pipeline.
[0003] The existing pipeline compensator can generate deformation when subjected to thermal stress, thereby releasing the thermal stress generated in the pipeline and reducing the damage to the pipeline. However, when the temperature change caused by external factors is too large, the temperature fluctuation of the heat supply pipeline may exceed the design bearing range of the compensator, resulting in fatigue or damage of the compensator material.
[0004] Therefore, in view of the above problems, the utility model provides a heat supply pipeline compensator to solve the above problems. SUMMARY
[0005] The utility model aims at solving one of the above technical problems at least to some extent.
[0006] To achieve the above purpose, the utility model provides a heat supply pipeline compensator in the first aspect, which comprises a heat supply pipeline, a compensator, a moving pipe, a sealing assembly and a connecting assembly. The heat supply pipeline and the moving pipe are respectively arranged at two ends of the compensator through the connecting assembly. The sealing assembly is arranged at the connection between the moving pipe and the compensator. The compensator comprises a threaded pipe and a metal pipe. The threaded pipe is fixedly arranged at one end of the metal pipe. The other end of the metal pipe is sleeved on the moving pipe. The connecting assembly comprises a connecting disc, a limiting screw and a fixing screw. Four mounting holes are equidistantly arranged on the connecting disc. The mounting holes are matched with the limiting screw and the fixing screw. The heat supply pipeline and the moving pipe are arranged at two ends of the compensator through the connecting disc. Four limiting screws are arranged on the connecting disc in a staggered manner. Four fixing screws are arranged on the connecting disc in a staggered manner.
[0007] In addition, the heat supply pipeline compensator according to the utility model can have the following additional technical features.
[0008] Further, the sealing assembly comprises limiting rings and sealing rings, wherein four limiting rings are fixedly arranged on two ends of the moving pipe and one end of the metal pipe away from the threaded pipe, and four sealing rings are arranged in the moving pipe and the metal pipe respectively and are located on one side of the limiting rings.
[0009] Further, the connecting plates are arranged on one end of the heat supply pipe close to the threaded pipe, the other end of the threaded pipe and the middle line of the moving pipe.
[0010] Further, one end of the limiting screw rod extends through the connecting plates arranged on the threaded pipe, the heat supply pipe and the moving pipe and extends to the outside, and one end of the fixing screw extends through the connecting plates arranged on the heat supply pipe and the threaded pipe and extends to the outside.
[0011] Further, limiting nuts are arranged on the extending ends of the limiting screw rod and the fixing screw.
[0012] According to the heat supply pipe compensator, the moving pipe can drive the compensator to move on the moving pipe, so that the moving distance of the pipe compensator is increased, and when the moving distance is too large, the threaded pipe will be deformed, so that the material fatigue or damage of the compensator is further prevented.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0021] The heating pipeline compensator of this utility model embodiment will be described below with reference to the accompanying drawings.
[0022] like Figs. 1 to 3 As shown, the heating pipeline compensator of this utility model embodiment may include: heating pipeline 1, compensator 2, moving pipe 3, sealing component 4, and connecting component 5.
[0023] It should be noted that the heating pipe 1 and the moving pipe 3 are respectively installed on both ends of the two compensators 2 through the connecting component 5, and the sealing component 4 is respectively installed at the connection between the moving pipe 3 and the compensator 2.
[0024] It is understandable that when this device is installed on the heating pipe 1, when the inside of the heating pipe 1 begins to heat up and thus generates thermal stress, the heating pipe 1 will drive the compensator 2 to move on the moving pipe 3, thereby compensating for the movement of the heating pipe 1 caused by the thermal stress.
[0025] Specifically, the compensator 2 includes a threaded pipe 21 and a metal pipe 22.
[0026] It should be noted that the threaded tube 21 is fixedly mounted on one end of the metal tube 22, and the other end of the metal tube 22 is sleeved on the movable tube 3.
[0027] It is understandable that the metal tube 22 can generate supporting force to enable it to move better on the moving tube 3, while the threaded tube 21 set on one side will deform when the metal tube 22 moves to the end, thereby preventing the material from fatigued or damaged due to excessive temperature changes.
[0028] Specifically, the connecting component 5 includes: a connecting plate 51, a limiting screw 52, and a fixing screw 53.
[0029] It should be noted that four mounting holes 511 are equidistantly formed on the connecting disc 51, and the mounting holes 511 are matched with the limiting screw 52 and the fixing screw 53 respectively, the heat supply pipeline 1 and the moving pipe 3 are arranged on both ends of the compensator 2 through the connecting disc 51 respectively, the four limiting screws 52 are arranged on the connecting disc 51 in a staggered manner respectively, and the four fixing screws 53 are arranged on the connecting disc 51 in a staggered manner respectively.
[0030] It should be further noted that the connecting disc 51 is arranged on the heat supply pipeline 1 close to the threaded pipe 21, the other end of the threaded pipe 21 and the middle line position of the moving pipe 3 respectively, one end of the limiting screw 52 extends outward through the connecting disc 51 arranged on the threaded pipe 21, the heat supply pipeline 1 and the moving pipe 3 respectively, one end of the fixing screw 53 extends outward through the connecting disc 51 arranged on the heat supply pipeline 1 and the threaded pipe 21 respectively, and the limiting nut 6 is arranged on the extending end of the limiting screw 52 and the fixing screw 53 respectively, and the limiting nut 6 on the fixing screw 53 is closely attached to one side of the connecting disc 51.
[0031] It can be understood that when the heat supply pipeline 1 moves, because the threaded pipe 21 is connected with the heat supply pipeline 1 through the connecting disc 51 and the fixing screw 53, when the heat supply pipeline 1 moves, the threaded pipe 21 will also move, so that the metal pipe 22 sleeved on one end of the moving pipe 3 moves along the moving pipe 3, thereby compensating the moving distance of the heat supply pipeline 1.
[0032] It can be further understood that the limiting screw 52 arranged thereon prevents the metal pipe 22 from deviating when moving, so that it can only move horizontally, and the limiting nut 6 arranged thereon prevents the limiting screw 52 from being separated from the connecting disc 51 so as to lose the limiting effect, and the limiting nut 6 arranged on the fixing screw 53 prevents the heat supply pipeline 1 and the compensator 2 from being separated, and closely attaches to prevent air leakage.
[0033] Specifically, the sealing assembly 4 comprises a limiting ring 41 and a sealing ring 42.
[0034] It should be noted that the four limiting rings 41 are fixedly arranged on both ends of the moving pipe 3 and the inner wall of the metal pipe 22 away from the threaded pipe 21 respectively, and the four sealing rings 42 are arranged on the moving pipe 3 and the metal pipe 22 respectively and are located on one side of the limiting ring 41.
[0035] It can be understood that because the sealing ring 42 is arranged in the moving pipe 3 and the metal pipe 22 respectively, it is ensured that the metal pipe 22 will not leak air when moving along the moving pipe 3, and the limiting ring 41 arranged on one side can prevent the sealing ring 42 from being separated during movement.
[0036] In conclusion, the heat supply pipeline compensator according to the embodiment of the utility model can increase the moving distance of the pipeline compensator, thereby preventing the material fatigue or damage of the compensator.
