Technical Field

[0001] This utility model relates to the field of steam transmission technology, and more specifically, it relates to a prefabricated steam insulation pipe with anti-fall function. Background Technology

[0002] Steam transport is the process of safely and efficiently delivering high-temperature, high-pressure steam generated by a boiler to heat-using equipment through an insulated pipeline network. The core of this process lies in insulation, drainage, pressure reduction, and monitoring. It is necessary to minimize heat loss and the risk of water hammer while ensuring that the terminal receives stable, dry steam to provide a reliable heat source for industrial heating, power generation, or heating.

[0003] During construction, some pipes need to be installed vertically, which can cause the insulation layer of the pipes to sag, resulting in a lack of insulation at the top of the pipes and affecting their insulation performance. Utility Model Content

[0023] First Embodiment

[0024] Reference Figures 1 to 3 This utility model provides a technical solution: a prefabricated steam insulation pipe with anti-fall function, including a working steel pipe 1, an outer protective pipe 2 sleeved on the working steel pipe 1, an insulation layer 3 between the working steel pipe 1 and the outer protective pipe 2, the insulation layer 3 including a plurality of calcium silicate tiles 301, the plurality of calcium silicate tiles 301 being stacked sequentially around the axis of the working steel pipe 1, and a plurality of anti-fall components for preventing the calcium silicate tiles 301 from falling on the working steel pipe 1;

[0025] like Figure 1The calcium silicate tile 301 is divided into multiple layers. Each layer of calcium silicate tile 301 is stacked sequentially around the axis of the working steel pipe 1. When the working steel pipe 1 is installed vertically, multiple calcium silicate tiles 301 in the insulation layer 3 will fall down. The longer the working steel pipe 1 is, the more serious the fall will be, causing gaps in the insulation layer 3 at the upper end of the working steel pipe 1. As a result, the upper end of the working steel pipe 1 lacks the insulation layer 3, which affects the insulation performance.

[0026] Specifically, each of the fall arrestor components includes two pipe clamps 4, which are fixedly connected by multiple fasteners 5 and clamp the working steel pipe 1. The fasteners 5 can be bolts and nuts. Each pipe clamp 4 includes a clamping plate 401, a rib plate 402 and a fan-shaped plate 403. The clamping plate 401 abuts against the working steel pipe 1. Multiple rib plates 402 are fixedly connected to the clamping plate 401, and the multiple rib plates 402 are fixedly connected to the fan-shaped plate 403.

[0027] like Figure 2 and Figure 3 When the two pipe clamps 4 are fixed by multiple fasteners 5, the two clamping plates 401 will clamp the working steel pipe 1. The two clamping plates 401 support the fan-shaped plate 403 by multiple ribs 402 on them respectively, and the two fan-shaped plates 403 can support the calcium silicate tile 301.

[0028] Two pipe clamps 4 are installed at regular intervals on the working steel pipe 1, so as to support the calcium silicate tiles 301 in the insulation layer 3 in sections, prevent the calcium silicate tiles 301 from falling, and ensure the insulation performance of the upper insulation layer 3 of the working steel pipe 1.

[0029] Second Embodiment

[0030] Reference Figure 4 and Figure 5 Specifically, each of the fall arrestor components includes an annular support plate 6 and a support member 7. There are two annular support plates 6. The two annular support plates 6 are fixedly connected by welding and sleeved on the working steel pipe 1. Multiple support members 7 are fixedly connected to the working steel pipe 1. The multiple support members 7 are located below the two annular support plates 6 and support the two annular support plates 6.

[0031] Two annular support plates 6 are joined together to form a complete ring and fitted onto the working steel pipe 1. Then, the joint of the two annular support plates 6 is welded. Multiple support members 7 can support the two annular support plates 6, and the two annular support plates 6 can support the calcium silicate tile block 301.

[0032] Annular support plates 6 and support members 7 are installed at regular intervals on the working steel pipe 1, so as to support the calcium silicate tiles 301 in the insulation layer 3 in sections, prevent the calcium silicate tiles 301 from falling, and ensure the insulation performance of the upper insulation layer 3 of the working steel pipe 1.

[0033] Third Embodiment

[0034] Reference Figure 6 Specifically, each of the fall arrestor components includes two brackets 8, which are sleeved on the working steel pipe 1. Each bracket 8 includes a lower support plate 801, a vertical plate 802, and an upper top plate 803. The lower support plate 801 abuts against the working steel pipe 1, and multiple vertical plates 802 are fixedly connected to the lower support plate 801. The multiple vertical plates 802 are fixedly connected to the upper top plate 803.

[0035] Two supports 8 are connected and fitted onto the working steel pipe 1. The lower support plate 801 is supported by the calcium silicate tile 301 below it. The lower support plate 801 is supported by multiple vertical plates 802 on it, which in turn support the upper top plate 803. The upper top plate 803 can then support the calcium silicate tile 301 above it. Calcium silicate tile 301 can also be placed between the upper top plate 803 and the lower support plate 801.

[0036] Two supports 8 are placed at regular intervals on the working steel pipe 1 to support the calcium silicate tiles 301 in the insulation layer 3 in sections, reducing the sagging of the calcium silicate tiles 301 and ensuring the insulation performance of the upper insulation layer 3 of the working steel pipe 1. Furthermore, the supports 8 do not require welding or other methods of fixing, making installation simpler.

[0037] Working principle: Anti-fall components are installed at regular intervals on the working steel pipe 1, which can support the calcium silicate tiles 301 in the insulation layer 3 in sections, prevent the calcium silicate tiles 301 from falling, and ensure the insulation performance of the upper insulation layer 3 of the working steel pipe 1.

[0038] It should be noted that the standard parts used in this application can all be purchased from the market, and the specific connection methods of each part are all conventional methods such as bolts, rivets, and welding that are mature in the existing technology. Furthermore, the machinery, parts, and equipment all adopt conventional models in the existing technology, and will not be described in detail here.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
