Description

Technical Field

[0001] The utility model relates to the field of steam pipelines, in particular to an assembled prefabricated overhead steam pipeline. Background Art

[0002] Steam pipes are a type of thermal pipe, primarily used to transport steam. In the industrial sector, steam pipes play a vital role, transporting heat energy to where it's needed to meet production, heating, or power generation needs. Existing steam pipes are typically single-layer designs.

[0003] Existing steam pipes are usually single-layered in use, so that when steam passes through the steam pipe, the temperature of the steam can be directly dissipated to the outside through the pipe as a medium, which can easily lead to rapid heat leakage of the steam and affect the thermal insulation performance of the steam pipe.

[0004] Therefore, in view of the fact that the heat leakage of the above-mentioned steam is fast and affects the thermal insulation performance of the steam pipe, an assembled prefabricated overhead steam pipe can be designed. By designing the steam pipe into a double-layer design, an air layer is created between the double-layer pipes to block the transfer of heat, thereby facilitating the solution to the above-mentioned problem. Utility Model Content

[0005] In order to overcome the problem that existing steam pipes are usually single-layered in use, the temperature of the steam can be directly dissipated to the outside through the pipe as the medium when the steam passes through the steam pipe, which can easily lead to rapid heat leakage of the steam and affect the thermal insulation performance of the steam pipe.

[0006] The technical solution of the utility model is: an assembled prefabricated overhead steam pipeline, comprising a first-level pipeline, a rubber insulation sleeve, a second-level pipeline, a first-level insulation inner pipe and a second-level insulation inner pipe; a second-level pipeline is matched with the first-level pipeline, the outer ends of the first-level pipeline and the second-level pipeline are respectively provided with a first-level insulation groove and a second-level insulation groove, the outer ends of the first-level pipeline and the second-level pipeline are respectively provided with two groups of rubber insulation sleeves, the interior of the first-level pipeline is provided with a first-level insulation inner pipe, and the interior of the second-level pipeline is provided with a second-level insulation inner pipe.

[0007] Preferably, by combining the first-level pipe, the second-level pipe, the first-level insulation inner pipe, the second-level insulation inner pipe and the rubber insulation sleeve, compared with the single-layer steam pipe currently on the market, after the first-level pipe, the second-level pipe, the first-level insulation inner pipe, the second-level insulation inner pipe and the rubber insulation sleeve are installed and combined, since the steam flows in the first-level insulation inner pipe and the second-level insulation inner pipe, the first-level pipe and the second-level pipe together with the rubber insulation sleeve can effectively block the heat of the steam from dissipating and transmitting outward, thereby greatly improving the insulation effect of the steam pipe.

[0008] Preferably, the inner walls at both ends of the first-level pipe are fitted with a first-level threaded sleeve, the outer sides of both ends of the first-level insulation inner pipe are fitted with a second-level threaded sleeve, the outer sides of both ends of the second-level pipe are provided with a first-level threaded groove, and the inner walls at both ends of the second-level insulation inner pipe are fitted with a second-level threaded groove. By combining the first-level threaded sleeve, the second-level threaded sleeve, the first-level threaded groove and the second-level threaded groove, the connection between the first-level pipe and the second-level pipe can play a bidirectional locking role, thereby strengthening the connection strength between the first-level pipe and the second-level pipe.

[0009] Preferably, the first-level threaded sleeve and the first-level threaded groove are matched with each other, and the second-level threaded sleeve and the second-level threaded groove are matched with each other. By combining the first-level threaded sleeve, the second-level threaded sleeve, the first-level threaded groove and the second-level threaded groove, when installing the steam pipe, the staff can twist the first-level pipe so that the first-level threaded sleeve of the first-level pipe is tightened along the first-level threaded groove of the second-level pipe. At the same time, the first-level insulation inner pipe in the first-level pipe can be tightened along the second-level threaded groove of the second-level insulation inner pipe through the second-level threaded sleeve, thereby completing the connection between the first-level pipe and the second-level pipe.

[0010] Preferably, a first-level partition is provided between the first-level pipe and the first-level insulation inner pipe, and there are sixteen groups of first-level partitions. The sixteen groups of first-level partitions are arranged around the first-level pipe and the first-level insulation inner pipe, and multiple groups of first-level triangular insulation chambers are opened between the sixteen groups of first-level partitions. The first-level partition is combined with the second-level partition, so that when the steam passes through the first-level insulation inner pipe and the second-level insulation inner pipe, the first-level triangular insulation chamber and the second-level triangular insulation chamber form an air layer. Since air is a poor conductor of heat, the heat of the steam can be effectively blocked and conducted through this air layer.

[0011] Preferably, a secondary partition is provided between the secondary pipe and the secondary insulation inner pipe, and there are sixteen groups of secondary partitions. The sixteen groups of secondary partitions are arranged around the secondary pipe and the secondary insulation inner pipe, and multiple groups of secondary triangular insulation chambers are opened between the sixteen groups of secondary partitions. By combining the primary partition and the secondary partition, the separated primary triangular insulation chamber and the secondary triangular insulation chamber play an insulation role. At the same time, multiple groups of primary partitions and multiple groups of secondary partitions can improve the overall structural stability of the steam pipe.

[0012] Preferably, two sets of first-level limit rings are respectively provided at both ends of the first-level insulation tank, two sets of second-level limit rings are respectively provided at both ends of the second-level insulation tank, and two sets of sealing rings are respectively provided at both ends of the first-level pipe. By combining the two sets of sealing rings, after the first-level pipe and the second-level pipe are assembled and docked, the two sets of sealing rings can further prevent steam from leaking from the connection between the first-level pipe and the second-level pipe.

[0013] Preferably, the centers of the two groups of rubber insulation sleeves are provided with sleeve holes, and the two groups of rubber insulation sleeves are respectively sleeved on the outer ends of the first-level insulation groove and the second-level insulation groove through the sleeve holes. The outer ends of the two groups of rubber insulation sleeves are provided with overhead suspension grooves, and there are multiple groups of overhead suspension grooves. The multiple groups of overhead suspension grooves are linearly arranged along the outer ends of the two groups of rubber insulation sleeves. By combining the two groups of rubber insulation sleeves with the overhead suspension grooves, the rubber insulation sleeves can effectively reduce the heat transfer loss of the pipeline through their high density and good thermal insulation performance. At the same time, when the staff erects the steam pipeline in the air, they can wrap the straps around the overhead suspension grooves according to their needs to install and fix it.

[0014] Beneficial effects of the utility model:

[0015] 1. By combining the first-level pipe, the second-level pipe, the first-level insulation inner pipe, the second-level insulation inner pipe and the rubber insulation sleeve, compared with the single-layer steam pipes currently on the market, after the first-level pipe, the second-level pipe, the first-level insulation inner pipe, the second-level insulation inner pipe and the rubber insulation sleeve are installed and combined, since the steam flows in the first-level insulation inner pipe and the second-level insulation inner pipe, the first-level pipe and the second-level pipe, together with the rubber insulation sleeve, can effectively block the heat of the steam from dissipating and transmitting outward, thereby greatly improving the insulation effect of the steam pipe. By combining the first-level threaded sleeve, the second-level threaded sleeve, the first-level thread groove and the second-level thread groove, the connection between the first-level pipe and the second-level pipe can play a two-way locking role, thereby strengthening the connection strength between the first-level pipe and the second-level pipe. By combining the first-level spacer and the second-level spacer, when the steam passes through the first-level insulation inner pipe and the second-level insulation inner pipe, an air layer is formed between the first-level triangular insulation chamber and the second-level triangular insulation chamber. Since air is a poor conductor of heat, the heat of the steam can be effectively blocked from conduction through this air layer. BRIEF DESCRIPTION OF THE DRAWINGS
