Description

Technical Field

[0001] This utility model relates to the field of compensator technology, specifically to a compensator with a protective structure. Background Technology

[0002] Pipeline compensators, also known as expansion joints or expansion valves, are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may lead to pipeline rupture and affect normal production. As an important component of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines.

[0003] Expansion joints (especially bellows expansion joints) are widely used in pipeline systems in industries such as heating, gas, chemical, and power. However, the core component of existing expansion joints, the bellows, is usually made of thin-walled metal, which has weak resistance to external mechanical damage. Due to the lack of protective structure, expansion joints are easily damaged by external impacts. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 One embodiment provided by this utility model: A compensator with a protective structure includes: The body includes the bellows compensator 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here. The protective mechanism includes a first protective cover 2, which is disposed on the surface of the bellows compensator 1. A fixing block 21 is fixedly connected to the surface of the first protective cover 2. The fixing block 21 is used to fix the positioning mechanism to the first protective cover 2. A rubber damping layer 22 is fixedly connected to the inner surface of the fixing block 21. The rubber damping layer 22 is used to achieve a damping effect, increase the friction between the spring 23 and the fixing block 21, and prevent the fixing from becoming loose. A spring 23 is fixedly connected to the inner surface of the fixing block 21. The spring 23 is used to push the connecting plate 24 and the insert rod 25 back to their original positions, so that the insert rod 25 is inserted into the fixing plate 27, thereby fixing the first protective cover 2 and the second protective cover 28 together. The surface of the spring 23 is coated with a damping material. A connecting plate 24 is fixedly connected to the surface of the spring 23. The connecting plate 24 is used to connect the spring 23, the insert rod 25 and the pull rod 26, and is also used to compress the spring 23, so that... Spring 23 deforms, and a plug rod 25 is fixedly connected to the side of connecting plate 24 away from spring 23. The plug rod 25 is used to insert into fixed plate 27, thereby fixing the first protective cover 2 and the second protective cover 28 together. A pull rod 26 is fixedly connected to the side of connecting plate 24 away from plug rod 25. The pull rod 26 is used to pull plug rod 25 backward, thereby inserting fixed plate 27 into the first protective cover 2 and enabling disassembly between the first protective cover 2 and the second protective cover 28, which is convenient for staff to inspect the bellows compensator 1. Fixed plate 27 is movably connected to the surface of plug rod 25. Fixed plate 27 is used to fix the first protective cover 2 and the second protective cover 28 together. The second protective cover 28 is fixedly connected to the upper surface of fixed plate 27.

[0018] Furthermore, the warning mechanism includes a mounting base 3, which is fixedly connected to the surface of the first protective cover 2. The mounting base 3 is used to install the reflector 33 on the first protective cover 2 and the second protective cover 28. A first magnetic block 31 is fixedly connected to the inner surface of the mounting base 3, and a second magnetic block 32 is magnetically connected to the surface of the first magnetic block 31. The first magnetic block 31 and the second magnetic block 32 are used to position the reflector 33, making the reflector 33 installed stably, and at the same time, the reflector 33 is detachable, so as to facilitate the disassembly and replacement of the reflector 33 by the staff. The reflector 33 is fixedly connected to the surface of the second magnetic block 32. The reflector 33 is used to reflect light and provide a warning, thereby preventing on-site personnel from touching the device at night.

[0019] Furthermore, the fixing blocks 21 are symmetrically distributed in two sets on both sides of the first protective cover 2. The fixing blocks 21 are used to fix the positioning mechanism on the first protective cover 2. The rubber damping layer 22 is cylindrical and is used to achieve a damping effect, increase the friction between the spring 23 and the fixing blocks 21, and prevent the fixing from becoming loose.

[0020] Furthermore, the two ends of the spring 23 are fixedly connected to the fixed block 21 and the connecting plate 24 respectively. The spring 23 is used to push the connecting plate 24 and the insert rod 25 back to their original positions, so that the insert rod 25 is inserted into the fixed plate 27, thereby fixing the first protective cover 2 and the second protective cover 28. The surface of the spring 23 is coated with damping material. The connecting plate 24 is slidably connected to the spring 23 and the rubber damping layer 22. The connecting plate 24 is used to connect the spring 23, the insert rod 25 and the pull rod 26, and at the same time to compress the spring 23, so that the spring 23 deforms.

[0021] Furthermore, the insertion rod 25 is slidably connected to the first protective cover 2 via the connecting plate 24. The insertion rod 25 is used to insert into the fixing plate 27, thereby fixing the first protective cover 2 and the second protective cover 28 together. The pull rod 26 is slidably connected to the fixing block 21 via the connecting plate 24. The pull rod 26 is used to pull the insertion rod 25 backward, thereby inserting the fixing plate 27 into the first protective cover 2 and enabling the disassembly of the first protective cover 2 and the second protective cover 28, which facilitates the maintenance of the bellows compensator 1 by the staff.

[0022] Furthermore, the fixing plate 27 is movably connected to the first protective cover 2 via the insert rod 25. The fixing plate 27 is used to fix the first protective cover 2 and the second protective cover 28 together. The second protective cover 28 is movably connected to the first protective cover 2 via the fixing plate 27. The first protective cover 2 and the second protective cover 28 are used to protect the bellows compensator 1, thereby preventing the bellows compensator 1 from being damaged by external impacts.

[0023] Furthermore, the mounting bases 3 are evenly distributed in four groups on the surfaces of the first protective cover 2 and the second protective cover 28. The mounting bases 3 are used to install the reflector 33 on the first protective cover 2 and the second protective cover 28. The first magnetic block 31 and the second magnetic block 32 are used to position the reflector 33, so that the reflector 33 is installed stably and can be disassembled, so as to facilitate the disassembly and replacement of the reflector 33 by the staff. The reflector 33 is movably connected to the mounting base 3 through the first magnetic block 31 and the second magnetic block 32. The reflector 33 is used to reflect light and provide a warning, so as to prevent the personnel on site from touching the device at night.

[0024] Working principle: Pulling the lever 26 moves the insert rod 25 backward, and then inserts the fixing plate 27 into the first protective cover 2, so that the first protective cover 2 and the second protective cover 28 are together. When the lever 26 is released, the spring 23 will push the insert rod 25 into the fixing plate 27, thereby fixing the first protective cover 2 and the second protective cover 28. The first protective cover 2 and the second protective cover 28 can realize the protection function of the bellows compensator 1, thereby avoiding damage to the bellows compensator 1 from external impacts.

[0025] Insert the reflector 33 into the mounting base 3, so that the first magnetic block 31 and the second magnetic block 32 are attracted together to position the reflector 33. The reflector 33 can play a reflective warning role, thereby preventing on-site personnel from touching the device at night.
