[0002] Most of the cold water pipes of air conditioners in civil buildings are insulated with rubber and plastic insulation materials to reduce heat loss and achieve aesthetic effects. The commonly used insulation construction method is mainly manual strong pressure for overlapping the insulation layer at the joint surface and bend of special-shaped pipes, and fixed by adhesive.

[0038] Please refer to Figure 1 and Figure 2 According to the pipeline rubber-plastic insulation construction method provided in this application, the following steps are included:

[0039] S100, measuring the pipeline that needs to be insulated, and determining the main pipeline 1 and branch pipeline 3;

[0040] S200, setting out on the thermal insulation material to be cut;

[0041] S300, cutting the thermal insulation material to obtain a thermal insulation layer;

[0042] S400, installing the insulation layer on the pipeline;

[0043] Step S200 includes:

[0044] S210, laying out the main road insulation layer 2, the main road insulation layer 2 including a first edge line 6, the first edge line 6 being a laying out line of an intersection line between an outer surface of the main road insulation layer 2 and an outer surface of the branch road 3;

[0045] S220, setting out the branch insulation layer 4, the branch insulation layer 4 including a second edge line 7, the second edge line 7 being a setting out line of an intersection line between an outer surface of the branch insulation layer 4 and an outer surface of the main insulation layer 2;

[0046] Step S300 includes:

[0047] S310, cutting the insulation material used for the main road insulation layer 2, when cutting the first side line 6, first cut perpendicularly to the first side line 6, and then trim the angles from the center line of the cut surface to both sides;

[0048] S320, cutting the insulation material used for the branch insulation layer 4, when cutting the second edge line 7, first cut perpendicularly to the second edge line 7, and then trim the angles from the top of the intersection line between the outer surface of the branch insulation layer 4 and the outer surface of the main insulation layer 2 to both sides.

[0049] The main circuit 1 refers to the main circuit of the water flow in the pipeline, and the branch circuit 3 refers to the branch circuit of the water flow in the pipeline. The main circuit 1 and the branch circuit 3 intersect through multiple channels or various devices, such as Figure 1 and Figure 2 In the tee shown, the main circuit 1 is a loop determined by two coaxial interfaces of the tee, and the branch circuit 3 is a loop determined by the remaining interface of the tee.

[0050] by Figure 1 and Figure 2 Taking the tee shown as an example, the top of the intersection line is the end of the intersection line closest to the branch road 3, and correspondingly, the bottom of the intersection line is the end closest to the main road 1.

[0051] The insulation layer is a general term for the insulation material wrapped around the outside of the pipeline in the pipeline rubber and plastic insulation construction method. The branch insulation layer 4 and the main insulation layer 2 are both part of the insulation layer.

[0052] The pipeline rubber-plastic insulation construction method provided in the present application has at least the following technical effects: a layout line is made according to the intersection line, and then a branch insulation layer 4 and a main insulation layer 2 are made based on the layout line, so that the branch insulation layer 4 and the main insulation layer 2 have a better overlapping effect when wrapped on the pipeline, thereby improving the tightness of the overlapping surface and reducing the mutual extrusion of the overlapping parts.

[0053] On the one hand, although the outer surface of the main insulation layer 2 and the outer surface of the branch 3 can be well matched based on the first edge line 6, and the outer surface of the branch insulation layer 4 and the outer surface of the main insulation layer 2 can be well matched based on the second edge line 7, considering the influence of thickness, the inner surface of the main insulation layer 2 will be squeezed with the outer surface of the branch 3, and the inner surface of the branch insulation layer 4 will be squeezed with the outer surface of the main insulation layer 2.

[0054] On the other hand, since the branch insulation layer 4 and the main insulation layer 2 are cut and made by plate-shaped insulation materials and then bent and wrapped on the pipeline, when bending, the parts of the branch insulation layer 4 and the main insulation layer 2 on the inner side of the neutral plane will be subjected to pressure, thereby causing extrusion and wrinkles.

[0055] If these extrusions and wrinkles are not dealt with, they will affect the overlapping effect between the branch insulation layer 4 and the main insulation layer 2, and may also cause the branch insulation layer 4 and the main insulation layer 2 to peel off or even fall off after long-term use. Through further corner trimming operations, the extrusion and wrinkles caused by bending can be reduced, thereby improving the reliability and tightness of the insulation layer installation.

[0056] Further references Figure 3 In some embodiments, in step S310, the angle is trimmed from 0 degrees to γ, where γ is equal to half of the angle between the two bottom ends of the intersection line of the outer surface of the main road insulation layer 2 and the inner surface of the branch road insulation layer 4 relative to the axis of the main road 1. In step S320, the angle is trimmed from 0 degrees to β, where the complementary angle of β is equal to half of the angle between the two bottom ends of the intersection line of the outer surface of the main road insulation layer 2 and the outer surface of the branch road insulation layer 4 relative to the axis of the main road 1. Such a trimming angle can effectively reduce extrusion and wrinkles without cutting too much insulation material, thereby avoiding gaps at the overlap due to insufficient material.

[0057] In order to improve the accuracy of the lofting line, when making the lofting line from the intersecting line, as many lofting points as possible are required. According to some embodiments of the present application, when lofting, the lofting points are determined by using an equally divided angle θ of no more than 30 degrees. This can ensure the fit between the cut branch insulation layer 4 and the main insulation layer 2.

[0058] According to some embodiments of the present application, step S200 includes: S230, setting out the corner insulation layer; step S300 includes: S330, cutting the insulation material used for the corner insulation layer. In some cases, such as corner transitions, shape mutations, etc., there is no intersection line, and the corner insulation layer can be used to fill the gap. For example, refer to Figure 4 Taking the position of valve 16 as an example, there is a sudden change in shape due to the size difference between valve 16 and main pipe 1. Since the operating part of valve 16 is the end of the pipeline, there is also a sudden change in shape. At this time, the corner insulation layer can be used to fill the gap in the sudden change position to reduce the area of ​​the pipeline exposed to the outside.

[0059] However, refer to Figure 4 and Figure 5At this time, the fitting effect between the corner insulation layer and other insulation layers may not be ideal. Therefore, in some embodiments, step S300 includes: S340, cutting a sector-shaped gap-filling unit 10, the angle of the gap-filling unit 10 is greater than angle δ, and angle δ is equal to the angle between adjacent surfaces of adjacent insulation layers. The gap-filling unit 10 is also a part of the insulation layer. The gap-filling unit 10 can fill the gap between the corner insulation layer and other insulation layers to avoid weak positions. Of course, the use scenario of the gap-filling unit 10 is not limited to the gap between the corner insulation layer and other insulation layers. If there are gaps in other adjacent insulation layers that cannot fit tightly, the gap-filling unit 10 may also be applicable.

[0060] Moreover, by making the angle of the gap-filling unit 10 greater than the angle δ, when the gap-filling unit 10 is inserted between two adjacent insulation layers, the gap-filling unit 10 is subjected to a certain extrusion force, thereby making the connection between the gap-filling unit 10 and other insulation layers closer and the installation more secure.

[0061] Specifically, in some embodiments, in step S330, the angle of the gap filling unit 10 is equal to δ+3 degrees. Such an angle can ensure a certain degree of installation firmness, and will not cause deformation or even wrinkles of the insulation layer due to excessive squeezing force.

[0062] In some embodiments, reference Figure 6 The gap-filling unit 10 cuts and blanks the solid rubber-plastic insulation rod 13 .

[0063] According to some embodiments of the present application, in step S400, the thermal insulation layer is coated and bonded in the order of equipment, valve 16, multi-way, elbow, and finally straight pipe section. Since the straight pipe section in the pipeline has the simplest shape and the thermal insulation layer is most convenient to process and modify, the thermal insulation layer in the complex position is installed first, so that the thermal insulation layer in the complex position can be compensated by the thermal insulation layer of the straight pipe section, thereby improving the installation quality of the thermal insulation layer.

[0064] Similarly, in some embodiments, in step S400, the main insulation layer 2 is installed first, then the branch insulation layer 4 is installed, the remaining insulation layers are installed first, and finally the gap filling unit 10 is installed. At this time, the gap filling unit 10 can be used as compensation between adjacent insulation layers.
