Description

Technical Field

[0001] This utility model relates to the field of bellows compensator technology, and in particular to a thermal insulation structure for a compensator. Background Technology

[0002] In pipelines of industries such as petroleum, chemical and metallurgy, in addition to corrosion resistance requirements, corrugated compensators are often used to compensate for the thermal expansion and contraction of the pipeline caused by the medium and to offset installation deviations. Their flexible connection can also improve the mechanical damage caused by mechanical vibration between the inlet and outlet of fans and pumps and the pipeline.

[0003] Expansion joints are commonly used outdoors and are greatly affected by the environment. Changes in the external environment can also affect the substances transported inside the expansion joint. Pipes connected to the expansion joint can be insulated with materials such as thermal insulation cotton. However, because the expansion joint itself is expandable, thermal insulation cotton and other materials cannot be directly laid on the outside of the expansion joint, and the directly laid insulation material cannot fit the expansion joint, thus affecting the normal insulation of the expansion joint. Therefore, an insulation structure for expansion joints is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a thermal insulation structure for a compensator, aiming to improve the problem that the thermal insulation material used in the compensator in the prior art is a conventional thermal insulation material, which cannot fit well with the compensator, thus affecting the thermal insulation effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a compensator insulation structure, including a compensator assembly, a second insulation pad, and a connecting ring. The compensator assembly includes a base plate, a top plate, mounting bolts, and an expansion joint. A slot is provided on the outer side of the expansion joint.

[0008] As a further description of the above technical solution:

[0009] The guide groove includes a connecting groove, an insertion groove, and a positioning groove. The connecting groove, insertion groove, and positioning groove are all formed on the outside of the mounting ring, and the insertion groove, connecting groove, and positioning groove are connected in sequence.

[0010] As a further description of the above technical solution:

[0011] The inner sides of the first and second heat insulation pads are both fixedly connected with a protrusion, and the outer sides of the first and second heat insulation pads are both provided with a recess. The size of the recess and the protrusion are matched.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the retaining ring and the retaining groove are first aligned, and then the insulation pad 2 and the expansion joint are connected under the action of the rubber ring 1, so as to realize the installation of the insulation material.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Reference Figures 1-3This utility model provides an embodiment of a compensator insulation structure, including a compensator assembly, a second insulation pad 10, and a connecting ring 6. The compensator assembly includes a base plate 1, a top plate 2, mounting bolts 3, and an expansion joint 4. The base plate 1 and the top plate 2 are located on the upper and lower sides of the expansion joint 4, respectively. The mounting bolts 3 are located on the periphery of the base plate 1 and the top plate 2, and the base plate 1 and the top plate 2 are connected by the mounting bolts 3. The base plate 1, the top plate 2, the mounting bolts 3, and the expansion joint 4 cooperate to assemble the compensator. This is prior art and will not be described in detail here. The expansion joint 4 has a slot 9 on its outer side. The end of the second insulation pad 10 is fixedly connected to a retaining ring 11. The retaining ring 11 and the slot 9 are engaged. During installation, the slot 9 and the retaining ring 11 are engaged to realize the connection between the second insulation pad 10 and the expansion joint 4. Multiple sets of second insulation pads 10 and expansion joints 4 are connected in this way, which facilitates the installation and disassembly of the insulation structure. A mounting ring 5 is fixedly connected to the bottom of the top plate 2, and a heat insulation pad 7 is fixedly connected to the bottom of the sleeve ring 6. The bottom of the mounting ring 5 and the heat insulation pad 7 are connected by a connecting component. The connection structure of the heat insulation pad 7 and the heat insulation pad 10 is different. The heat insulation pad 10 is used to connect with the expansion joint 4, which can achieve expansion and contraction while ensuring sealing. The heat insulation pad 7 is used to connect with the top plate 2 to seal and insulate the end, thereby ensuring the integrity of the entire insulation structure and the insulation effect at the edge.

[0031] Reference Figures 3-4 The connecting component includes a plug 20, which is slidably connected to the middle of the sleeve ring 6. A spring 19 is fixedly connected to one side of the plug 20. Multiple guide grooves are opened on the outer side of the mounting ring 5. The guide grooves include a connecting groove 21, an insertion groove 22, and a positioning groove 23. The connecting groove 21, the insertion groove 22, and the positioning groove 23 are all opened on the outer side of the mounting ring 5. The insertion groove 22, the connecting groove 21, and the positioning groove 23 are connected in sequence. A slot 24 is opened in the middle of the guide groove. The plug 20 and the slot 24 are interlocked. The plug 20 is inserted along the position of the insertion groove 22 in the guide groove. Then, the insulation pad 7 is rotated along the connecting groove 21. After the plug 20 is rotated to the end of the connecting groove 21, the insulation pad 7 is pulled down so that the plug 20 reaches the slot 24 located in the middle of the positioning groove 23. Under the action of the spring 19, the positioning groove 23 and the plug 20 are interlocked. The installation between the insulation pad 7 and the mounting ring 5 is realized in sequence. The operation is very simple and convenient.

[0032] Reference Figure 3Both the inner sides of insulation pad 1 7 and insulation pad 2 10 are fixedly connected with protrusions 13, and the outer sides of insulation pad 1 7 and insulation pad 2 10 are provided with recesses 14. The sizes of recesses 14 and protrusions 13 are matched. After multiple insulation pads 2 10 are installed, the outer periphery of insulation pad 2 10 can be inserted into the groove 8 of the lower insulation pad 2 10. At this time, protrusions 13 can contact the outer surface of recesses 14, thus ensuring the seal between two adjacent insulation pads 2 10. Since the external structure of insulation pad 1 7 is similar to that of insulation pad 2 10, this method can also be used to connect insulation pad 1 7 and insulation pad 2 10. Rubber rings 18 are fixedly connected to the inner parts of the outer ends of insulation pad 17 and insulation pad 20. The positions of rubber rings 18 and protrusions 13 are matched. After the insulation pads 20 are connected to each other, under the action of rubber rings 18, the protrusions 13 can be pulled inward, so that the protrusions 13 can fully contact the outer surface of the recesses 14, greatly improving the friction and thus ensuring the sealing effect. When the compensator is extended or retracted, the protrusions 13 will also slide on the outer surface of the recesses 14 under the action of rubber rings 18 to further ensure the insulation effect.

[0033] Reference Figure 3 Both insulation pad 1 (7) and insulation pad 2 (10) have a recessed portion 2 (15) along their middle edges. Both insulation pad 1 (7) and insulation pad 2 (10) have a protruding portion 2 (16) fixedly connected to their inner sides, with the protruding portion 2 (16) and the recessed portion 2 (15) being of compatible dimensions. Rubber rings 2 (17) are fixedly connected to the inside of the bent portions of both insulation pad 1 (7) and insulation pad 2 (10), with the rubber rings 2 (17) and the protruding portion 2 (16) being of compatible positions. Similar to the connection between the protruding portion 1 (13) and the recessed portion 1 (14), the recessed portion 2 (15) and the protruding portion 2 (16) are also directly connected via rubber rings 2 (17). This allows for the addition of a new sealing component between two adjacent insulation pads 2 (10), further ensuring airtightness and guaranteeing the insulation effect of the insulation structure.

[0034] Working principle: When installing the insulation structure, first remove the top plate 2 from above the mounting bolts 3. Then, insert the insulation pad 2 10 downwards. When the retaining ring 11 reaches the slot 9, it is deformed by the contraction of the rubber ring 12 and inserted into the middle of the slot 9, thus completing the connection between the insulation pad 2 10 and the expansion joint 4. By repeating this process, multiple insulation pads 2 10 can be installed on the outside of the expansion joint 4. Then, align the groove at the top of the insulation pad 7 with the protrusion at the bottom of the mounting ring 5, and align the insert block 20 with the insertion slot 22. Insert the insert block 20 into the insertion slot 22 and rotate the insulation pad 7 as a whole along the connecting slot 21. When the insert block 20 reaches the middle of the positioning slot 23, the spring 19 pushes the insert block 20 into the middle of the slot 24, thus completing the connection. Connecting the insulation pad 1 7 and the mounting ring 5 greatly improves installation efficiency. After installing the insulation pad 1 7 and multiple insulation pads 2 10, the top plate 2 with the insulation pad 1 7 installed is reinstalled above the mounting bolts 3. Then, the bottoms of the insulation pads 2 10 and 1 7 are inserted into the groove 8 in the middle of the lower insulation pad 2 10, so that the protrusion 1 13 is engaged with the recess 1 14 and the protrusion 2 16 is engaged with the recess 2 15. Then, under the action of the rubber ring 3 18 and the rubber ring 2 17, the connection between two adjacent insulation pads 2 10 can be achieved. This completes the installation of the external insulation structure of the compensator. The operation is simple and greatly improves the installation efficiency. Moreover, the installed insulation structure can expand and contract with the expansion and contraction of the compensator, thus greatly improving the practicality of the compensator.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
