Description

Technical Field

[0001] This utility model relates to the field of heat-insulated steam pipeline technology, specifically to a high-efficiency heat-insulated steam pipeline. Background Technology

[0002] Steam pipelines are a type of thermal pipeline, suitable for insulation projects of various cold and hot water pipelines at high and low temperatures. Steam pipelines have good mechanical and thermal insulation properties, and can typically withstand high temperatures of 120℃. By modification or combination with other insulation materials, they can withstand high temperatures of 180℃. They are suitable for insulation projects of various cold and hot water pipelines at high and low temperatures. Sleeve compensators are not suitable for use on steam pipelines because they require constant replacement of the packing, resulting in excessive maintenance. Axial corrugated compensators are also not suitable. Although axial corrugated compensators are aesthetically pleasing and require less maintenance when installed on steam pipelines, the thrust generated by the internal pressure is too great, increasing the cost of civil engineering.

[0003] Existing high-efficiency insulated steam pipes effectively reduce heat loss and improve energy efficiency by utilizing insulation materials with low thermal conductivity, high durability, excellent thermal stability, and thermal shock resistance. While these methods achieve the insulation effect of steam pipes, the insulation material is in long-term contact with the steam pipe during insulation. Condensation and other condensate can corrode the insulation board, causing the insulation material inside the board to corrode in contact with moisture. This reduces the insulation effect of the insulation board and can easily lead to excessive heat loss from the steam pipe. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-4As shown, this embodiment of a high-efficiency heat-insulating steam pipe includes an upper heat-insulating pipe 1 and a lower heat-insulating pipe 4 at the lower end of the upper heat-insulating pipe 1. Movable boxes 10 are evenly distributed inside both the upper heat-insulating pipe 1 and the lower heat-insulating pipe 4, with at least two movable boxes 10. A compression spring 11 is installed inside each movable box 10. One end of the compression spring 11 is connected to a clamping plate 5 via a compression rod 12. Through the design of the movable boxes 10, compression springs 11, and compression rods 12, the heat-insulating plates 7 on the upper and lower clamping plates 5 can compress and insulate the steam pipe body 6. An insert plate 8 is installed on one side of the bottom end of the clamping plate 5, and a slot 14 is opened on the other side of the bottom end of the clamping plate 5. A sealing rubber gasket 13 is arranged inside the slot 14, cooperating with the insert plate 8 and the sealing rubber gasket in the slot 14. The pad 13 makes direct contact, which can effectively prevent external moisture from corroding the insulation board 7. The insulation board 7 is installed on the inner wall of the clamping plate 5. A glass wool layer 16 is provided on one side of the insulation board 7. A nano heat insulation felt layer 15 is provided on the inner side of the glass wool layer 16. A rubber and plastic layer 17 is connected to the inner side of the nano heat insulation felt layer 15. An aluminum foil layer 9 is provided around the outer side of the glass wool layer 16, the nano heat insulation felt layer 15 and the rubber and plastic layer 17. The steam pipe body 6 is provided between the two clamping plates 5. The design of the aluminum foil layer 9 can form a moisture-proof layer on the outer side of the rubber and plastic layer 17, the nano heat insulation felt layer 15 and the glass wool layer 16, effectively preventing the condensate of the steam pipe body 6 from corroding the insulation board 7, and effectively ensuring the heat preservation effect of the steam pipe body 6.

[0025] like Figures 1-4 As shown, in this embodiment, four extension plates 3 are symmetrically arranged on both sides of the upper insulation pipe 1 and the lower insulation pipe 4, and a locking nut 2 is connected between the two extension plates 3 on one side.

[0026] like Figures 1-4 As shown, in this embodiment, the extension plate 3 is screwed to both the upper insulation pipe 1 and the lower insulation pipe 4, and the locking nut 2 is threaded to both the upper insulation pipe 1 and the lower insulation pipe 4. The design of the locking nut 2 makes it easy to lock the upper insulation pipe 1 and the lower insulation pipe 4, and makes it easy to disassemble and repair them at any time.

[0027] like Figures 1-4 As shown, in this embodiment, the movable box 10 is inserted into both the upper insulation pipe 1 and the lower insulation pipe 4. The two ends of the compression spring 11 are respectively screwed to the movable box 10 and the compression rod 12. The compression rod 12 is screwed to the clamping plate 5. When the steam pipe body 6 is clamped and insulated, the steam pipe body 6 will compress the compression rod 12, thereby realizing the retraction of the compression spring 11. This effectively ensures the tightness of the connection between the clamping plate 5 and the steam pipe body 6. Furthermore, when the device is subjected to a certain force from the outside, the shock-absorbing spring can buffer the steam pipe body 6, ensuring the stability of the operation of the steam pipe body 6.

[0028] like Figures 1-4As shown, in this embodiment, the active boxes 10 are evenly spaced, the insert plate 8 is connected to the clamping plate 5 with screws, the insert plate 8 is connected to the slot 14 with a slot, and the sealing rubber gasket 13 is bonded to the slot 14. The design of the insert plate 8 and the slot 14 realizes the sealed splicing between the two clamping plates 5. The design of the sealing rubber gasket 13 can effectively prevent external moisture from eroding the insulation board 7 between the clamping plates 5.

[0029] like Figures 1-4 As shown, in this embodiment, the insulation board 7 is inserted into the clamping plate 5, the glass wool layer 16 is connected to the insulation board 7 through a slot, and the nano heat insulation felt layer 15 is bonded to the glass wool layer 16. The design of the insulation board 7 can effectively reduce the heat loss inside the steam pipe body 6 and avoid the problem of excessive heat loss in the steam pipe body 6.

[0030] like Figures 1-4 As shown, in this embodiment, the rubber-plastic layer 17 is bonded to the nano-insulation and heat-preserving felt layer 15, and the aluminum foil layer 9 is bonded to the glass wool layer 16, the nano-insulation and heat-preserving felt layer 15, and the rubber-plastic layer 17. The insulation board 7 is composed of the aluminum foil layer 9, the glass wool layer 16, the nano-insulation and heat-preserving felt layer 15, and the rubber-plastic layer 17, which can achieve efficient heat preservation of the steam pipe body 6 by the upper insulation pipe 1.

[0031] The specific implementation process of this embodiment is as follows: When using the device, multiple steam pipe bodies 6 need to be spliced ​​together. After sealing the connection, the upper insulation pipe 1 and the lower insulation pipe 4 are spliced ​​together. With the design of the movable box 10, the compression spring 11, and the compression rod 12, the steam pipe body 6 will be compressed, so that the insulation plate 7 can make close contact with the steam pipe body 6. At the same time, when it is subjected to external impact, the compression spring 11 can buffer the force, effectively ensuring the stability of the steam pipe body 6. With the design of the extension plate 3 and the locking nut 2, the upper insulation pipe 1 and the lower insulation pipe 44 can be compressed. The quick-fixing design, combined with the insertion plate 8 and slot 14, enables the rapid splicing of the two clamping plates 5. The design of the sealing rubber gasket 13 effectively prevents outside air from entering the insulation board 7 through the splicing point. The design of the rubber-plastic layer 17, the nano-insulation felt layer 15, and the glass wool layer 16 enables the insulation board 7 to efficiently insulate the steam pipe body 6. The design of the aluminum foil layer 9 forms a moisture-proof layer on the outside of the rubber-plastic layer 17, the nano-insulation felt layer 15, and the glass wool layer 16, effectively preventing condensate from the steam pipe body 6 from corroding the insulation board 7 and effectively ensuring the insulation effect of the steam pipe body 6.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
