Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline construction, in particular to a pipeline protection structure. Background Art
[0002] The pipe insulation layer is also called the thermal pipe insulation layer, which refers to the insulation layer structure wrapped around the outside of the pipe that can play the role of heat preservation and heat insulation. The main function of the insulation layer is to reduce heat loss, so it must be made of materials with low thermal conductivity and good thermal insulation performance. The insulation layer material usually has the characteristics of low thermal conductivity, looseness and porosity, and needs to be used for more than ten years. However, the insulation material is loose and porous and easily absorbs water, so it is common practice to add a protective layer to the pipe insulation layer. The pipe protective layer is generally made of thin aluminum plates, iron sheets, and stainless steel skins rolled into cylinder sections. The cylinder sections are connected by an inserted sleeve structure, and the elbows are equipped with shrimp bend protective skin to form a closed protective layer.
[0003] Industrial pipelines in natural environments are affected by rain and snow. The two sections of the conventional protective layer are connected by an inserted sleeve. The interface is not waterproof. Rainwater can easily enter the insulation layer from the interface of the protective layer, causing the insulation layer to absorb water and significantly reduce the thermal insulation performance. The insulation layer may even become hardened, solidified, and collapsed, resulting in the inability to remove moisture from the insulation layer or evaporate and dry it for a long time, causing corrosion under the insulation layer. In addition, the operating temperature of most pipelines is relatively high. After the pipeline is in operation, the pipeline runs at a high temperature, and the pipeline expands and elongates due to thermal expansion. However, the temperature difference between the pipeline protective layer and the pipeline wall temperature is large, and the pipeline protective layer cannot elongate synchronously with the pipeline. The interface between the two sections of the cylinder is detached, resulting in the insulation layer being exposed. Utility Model Content
[0004] The utility model provides a pipeline protection structure which is easy to assemble and can be conveniently sleeved on a pipeline insulation layer to prevent rainwater from entering the insulation layer.
[0005] The utility model provides a pipeline protection structure, comprising a first pipe fitting and a second pipe fitting, wherein the first pipe fitting is provided with a protruding first wave node, the second pipe fitting is provided with a protruding second wave node, the end of the first pipe fitting is arranged inside the second pipe fitting, and the first wave node is stuck in a groove formed by the second wave node.
[0006] In one embodiment, the height of the first node is 1.0 mm to 1.5 mm, and the height of the second node is 2.0 mm to 2.5 mm.
[0007] In one embodiment, the thickness of the first tube and the thickness of the second tube are both 0.6 mm to 1.0 mm.
[0008] In one embodiment, the first pipe and the second pipe are both provided with a third node, the first node is arranged close to the end of the first pipe, the second node is arranged close to the end of the second pipe, and the third node is located between two of the first nodes or between two of the second nodes.
[0009] In one embodiment, the width of the first node, the width of the second node, and the width of the third node are all 12 mm to 20 mm, and the height of the third node is 1.5 mm to 2.0 mm.
[0010] In one embodiment, the third wave nodes are provided in plurality, and the distance between two adjacent third wave nodes is 160 mm to 220 mm.
[0011] In one embodiment, the distance between the first node and the adjacent third node is 160 mm to 220 mm, and the distance between the second node and the adjacent third node is 160 mm to 220 mm.
[0012] In one embodiment, the distance between the first wave node and the end surface of the first pipe is 25 mm to 30 mm, and the distance between the second wave node and the end surface of the second pipe is 25 mm to 30 mm.
[0013] In one embodiment, the first pipe member and the second pipe member are both made of aluminum alloy or stainless steel.
[0014] In one embodiment, the first node and the second node are both annular.
[0015] Compared with the prior art, the advantages of the utility model are:
[0016] 1. By setting the corrugated nodes, the rigidity of the first pipe and the second pipe can be increased, and the shape of the thermal insulation layer can be better protected from deformation;
[0017] 2. The corrugated nodes have a water-repellent function. When rain falls on the protective layer, it will flow in the direction guided by the corrugated nodes. In particular, two higher corrugated nodes are set at the interface of the protective layer pipe joints, which play the dual role of water-repellent and dam, preventing rainwater from entering the insulation layer through the pipe joint interface;
[0018] 3. The corrugated nodes act as expansion joints. Each corrugated node is an expansion joint. Each section of the protective layer has multiple expansion joints, so that the protective layer can expand and contract synchronously with the pipeline as the temperature of the pipeline changes, avoiding the exposure of the insulation layer caused by the failure of the protective layer to expand.
[0019] 4. The end of the first pipe can be inserted into the interior of the second pipe, and the first wave node on the first pipe is inserted into the groove formed by the second wave node on the second pipe, so that the first pipe and the second pipe are not easy to loosen after being connected, which is more secure than a simple insertion connection;
[0020] 5. It can resist wind-induced pipeline vibration. The wave nodes are equivalent to spoilers that break wind disturbances, which can ensure the safe operation of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model will be further described below in conjunction with the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a pipeline protection structure, including a first pipe fitting 1 and a second pipe fitting 2, the first pipe fitting 1 is provided with a protruding first wave node 100, the second pipe fitting 2 is provided with a protruding second wave node 200, the end of the first pipe fitting 1 is arranged inside the second pipe fitting 2, and the first wave node 100 is inserted into the groove 20 formed by the second wave node 200.
[0029] The end of the first pipe fitting 1 can be inserted into the interior of the second pipe fitting 2, and the first wave node 100 on the first pipe fitting 1 can be inserted into the groove 20 formed by the second wave node 200 on the second pipe fitting 2, so that the first pipe fitting 1 and the second pipe fitting 2 are not easy to loosen after being connected, and the installation method is simple, which can effectively protect the insulation layer, prevent rainwater from entering the insulation layer, and ensure the insulation effect of the pipeline.
[0030] like Figure 2As shown, in this embodiment, the height H1 of the first node 100 is 1.2 mm, and the height H2 of the second node 200 is 2.2 mm. The height H1 of the first node 100 and the height H2 of the second node 200 are both relatively low, so that the resistance when the first pipe 1 is inserted into the second pipe 2 is relatively small. Since the first node 100 is inserted into the groove 20 formed by the second node 200 on the second pipe 2, in order to make the first node 100 inserted more smoothly, the height H2 of the second node 200 should be greater than the height H1 of the first node 100, so as to further reduce the resistance when the first node 100 is inserted into the groove 20. After the first node 100 is inserted, the groove 20 will not be completely filled, and a certain amount of space will still be left.
[0031] In this embodiment, the thickness of the first pipe 1 and the thickness of the second pipe 2 are both 0.8 mm, and both are made of aluminum alloy. Aluminum alloy, as a common metal material, has the advantages of easy processing, low density, corrosion resistance and high structural strength, so it is easy to manufacture and install on site.
[0032] In other embodiments, the thickness of the first pipe 1 and the second pipe 2 are made of stainless steel.
[0033] like Figure 1 and Figure 3 As shown, the first pipe fitting 1 and the second pipe fitting 2 are both provided with a third wave node 300, the first wave node 100 is arranged near the end of the first pipe fitting 1, that is, the first wave node 100 is arranged at both ends of the first pipe fitting 1, the second wave node 200 is arranged near the end of the second pipe fitting 2, that is, the second wave node 200 is arranged at both ends of the second pipe fitting 2, and the third wave node 300 is located between the two first wave nodes 100 or between the two second wave nodes 200. The first pipe fitting 1 and the second pipe fitting 2 are both relatively long, and the third wave node 300 can play the role of a reinforcing rib, improve the structural strength of the first pipe fitting 1 and the second pipe fitting 2, make them less likely to deform, reduce the difficulty of installation, and improve the installation efficiency.
[0034] In this embodiment, the width of the first node 100, the width of the second node 200 and the width W of the third node 300 are all 16 mm, and the widths of the three nodes are kept uniform, which is more convenient for processing. In this embodiment, the height H3 of the third node 300 is 1.7 mm.
[0035] like Figure 1 As shown, the distance L1 between the second node 200 and the adjacent third node 300 is 190 mm, and the distance between the first node 100 and the adjacent third node 300 is also 190 mm (not shown in the figure).
[0036] In this embodiment, four third wave nodes 300 are provided, the distance between two second wave nodes 200 is L2=5L1, and the distance between two adjacent third wave nodes 300 is also 190 mm, so as to facilitate processing.
[0037] like Figure 1 As shown, the distance L3 between the second wave node 200 and the end face of the second pipe 2 is 27 mm, and the distance between the first wave node 100 and the end face of the first pipe 1 is also 27 mm (not shown in the figure). The first pipe 1 can extend into the second pipe 2 for a distance, so that the first pipe 1 is not easily separated from the second pipe 2, thereby improving the stability of the connection.
[0038] The first wave node 100 and the second wave node 200 are both annular. The first wave node 100 is arranged along the circumference of the first pipe 1, and the second wave node 200 is arranged along the circumference of the second pipe 2. The first pipe 1 and the second pipe 2 can rotate relative to each other without loosening.
[0039] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
