Description

Technical Field

[0002] Pipeline compensators are also called expansion joints or expansion joints, and are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract completely freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in the pipeline design, otherwise it may cause the pipeline to rupture and affect the normal production. As an important part of the pipeline project, the compensator plays an important role in ensuring the long-term normal operation of the pipeline. After retrieval, the relevant document (CN202122676610.1) discloses a compensator for a heating pipeline, including a first compensator, a second compensator and a compensator fastening mechanism; the first compensator and the second compensator are respectively provided with a first flange and a second flange, and the first compensator and the second compensator The relative first flange and second flange are connected by a compensator fastening mechanism. In this solution, a connecting block is provided on the flange of the existing compensator, so that when the two flanges on the two compensators are connected, the first positioning block and the second positioning block on the two flanges can be connected by the first fastener and the second fastener, thereby achieving the purpose of fastening the flange, improving the stability of the compensator installation, ensuring the sealing of the pipeline connection, and facilitating the disassembly and maintenance of the compensator.

[0003] However, the above structure still has some shortcomings. When in use, it can only perform ordinary flange connections on the connected heating pipes, and cannot strengthen and fix the connections, making it easy for the heating pipe connections to loosen and deviate when encountering external forces.

[0021] Please combine Figures 1 to 5 The compensator for heating pipes of this embodiment includes: a compensator body 1, a bellows 2 is fixedly connected to the compensator body 1, the bellows 2 is coated with anti-corrosion grease, both ends of the compensator body 1 are fixedly connected with connecting reinforcement rings 4, and both connecting reinforcement rings 4 are provided with reinforcing fixing mechanisms.

[0022] Through the above technical solution, the device can strengthen the fixation of the heating pipe connection, thereby reducing the impact of external force on the heating pipe connection. The anti-corrosion grease makes the corrugated pipe 2 more corrosion-resistant and improves the service life of the equipment.

[0023] The reinforcing fixing mechanism includes an equipment frame 5, which is fixedly connected to the connecting reinforcing ring 4. A forward and reverse threaded rod 6 is rotatably connected inside the equipment frame 5. Two internal thread blocks 7 are threadedly connected to the forward and reverse threaded rod 6. The bottom ends of the two internal thread blocks 7 are fixedly connected to an arc-shaped clamp 11. One side of the two internal thread blocks 7 and the two arc-shaped clamps 11 are fixedly connected to multiple springs 12, and the other ends of the multiple springs 12 are in contact with the equipment frame 5.

[0024] Through the above technical solution, when the forward and reverse threaded rods 6 rotate, they can drive the two arc-shaped clamps 11 to clamp the connection of the heating pipe, and then cooperate with multiple springs 12 to strengthen the fixation of the heating pipe connection.

[0025] A slide bar 8 is fixedly connected inside the equipment frame 5 , and two ends of the slide bar 8 respectively penetrate the corresponding internal thread blocks 7 and are slidably connected with the corresponding internal thread blocks 7 .

[0026] Through the above technical solution, the slide rod 8 plays a role in supporting and fixing the two internal thread blocks 7, and can also play a role in assisting the translation of the two internal thread blocks 7 when they translate.

[0027] One side of the two equipment frames 5 is fixedly connected to a same protective cylinder 3 , and the compensator body 1 is located inside the protective cylinder 3 .

[0028] Through the above technical solution, the protective cylinder 3 plays a role in protecting the bellows 2 and the compensator body 1.

[0029] A connecting hole is opened on one side of the device frame 5 , one end of the forward and reverse threaded rod 6 extends out of the connecting hole and is slidably connected to the connecting hole, and one end of the forward and reverse threaded rod 6 is fixedly connected to a rotating disk 10 .

The output rods of the plurality of telescopic sleeves 13 are fixedly connected to the corresponding internal thread blocks 7 and arc-shaped clamps 11 .

[0032] Through the above technical solution, multiple springs 12 cooperate with multiple telescopic sleeves 13 to assist the positive and negative threaded rods 6, the internal thread block 7 and the arc-shaped clamp 11 to strengthen and fix the connection of the heating pipe.

[0033] The implementation principle of a compensator for a heating pipe in the embodiment of the present application is:

[0034] When in use, two heating pipes are connected inside the compensator body 1, and then the rotating disk 10 is rotated to drive the forward and reverse threaded rods 6 to rotate. The rotation of the forward and reverse threaded rods 6 drives the two internal thread blocks 7 to translate. The translation of the two internal thread blocks 7 drives the two arc-shaped clamps 11 to translate. The two arc-shaped clamps 11 translate to clamp and fix the heating pipes. The two arc-shaped clamps 11 are further reinforced by the cooperation of multiple springs 12 and telescopic sleeves 13, so that the device can strengthen and fix the connection of the heating pipes when in use, so that the structure can reduce the influence of external forces.
