Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thermal pipe insulation, and in particular relates to an elbow outer protective shell and a thermal pipe with the elbow outer protective shell. Background Art
[0002] Thermal pipes in power plants, nuclear power plants, and chemical plants often require insulation. These pipes are coated with an insulation layer, which is then protected by an outer sheathing. Conventional sheathing is typically fabricated on-site, resulting in a low degree of factory production and a time-consuming and labor-intensive process. Furthermore, while sheathing fabrication is relatively simple for straight sections of thermal pipes, it is more difficult for curved sections. Gaps easily form at the sheathing joints, leading to the insulation material falling off, compromising thermal efficiency and creating an unsightly finish. To this end, the relevant technology proposes to use stainless steel plates to stamp two-piece half-elbow pipes. When in use, the two-piece bend pipes surround the insulation material at the elbow of the thermal pipe, and the open edges of the two-piece half-elbow pipes overlap, and then are fixed with screws or clamps. If screws are used for fixing, it is necessary to punch holes in the open edges of the two-piece bend pipes. Since the steel plate is thin, the threaded holes are difficult to process, and it is difficult to align the holes of the two-piece bend pipes when fixing. If clamps are used, the clamps also need to be made separately, and the clamps need to be welded, which makes installation difficult. There are many parts, the operation is cumbersome, and steps are formed on the surface, affecting the appearance. In addition, since the steel plate is thin, the two-piece bend pipe is difficult to process. During the stamping process, it is difficult to fix the steel plate, the two-piece bend pipe is difficult to process, the shape is difficult to guarantee, and the yield rate is low.

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0032] The elbow outer protective shell 100 of the embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1 to 8 As shown, the elbow outer protective shell 100 according to the embodiment of the present invention is elbow-shaped and includes a first half elbow 1 and a second half elbow 2.
[0033] The first half-bend tube 1 has a first opening 11, and the first opening 11 extends along the axial direction of the first half-bend tube 1. The first half-bend tube 1 has a first folded edge 12 extending along two edges of the first opening 11. It can be understood that the first folded edge 12 is bent outward from the edge of the first opening 11 of the first half-bend tube 1. Figure 1 Specifically, the first opening 11 of the first half elbow 1 has an inwardly curved side ( Figure 1 The right side of the middle) and the outward-curved side ( Figure 1 The inner curved side and the outer curved side respectively have a first folded edge 12 that is bent outward and extends along the axial direction of the first half bend tube 1. Preferably, as Figure 1 As shown, the tangent line of the first half elbow 1 at the junction with the first folded edge 12 is orthogonal to the first folded edge 12. Optionally, the angle between the tangent line and the first folded edge 12 can be greater than 90 degrees.
[0034] Similarly, the second half elbow 2 has a second opening 21, which extends along the axial direction of the second half elbow 2. The second half elbow 2 has a second folded edge 22 extending along the edge of the second opening 21, and the second folded edge 22 is bent outward from the edge of the second opening 21 of the second half elbow 2. The first half elbow 1 and the second half elbow 2 are adapted to be joined so that the first opening 11 is opposite to the second opening 21 and the first folded edge 12 is joined and overlapped with the second folded edge 22, thereby forming a complete elbow outer shell, as shown in FIG. Figure 5 shown.
[0035] According to the elbow outer protective shell 100 of the embodiment of the present invention, a first folded edge 12 is provided on the inner and outer curved sides of the first opening 11 of the first half elbow 1, and a second folded edge 22 is provided on the inner and outer curved sides of the second opening 21 of the second half elbow 2. Thus, when the first half elbow 1 and the second half elbow 2 are combined to enclose the thermal insulation material at the elbow of a thermal pipe, for example, the first half elbow 1 and the second half elbow 2 are buckled, and the first folded edge 12 of the first half elbow 1 and the second folded edge 22 of the second half elbow 2 are overlapped. By connecting the first folded edge 12 and the second folded edge 22, the first half elbow 1 and the second half elbow 2 are fixed together, forming the elbow outer protective shell 100 that encloses the thermal insulation material at the elbow of a thermal pipe, for example. Compared with the prior art, in which holes are first directly drilled on the half-bend pipe and then fixed with screws or clamps, the elbow outer protective shell 100 according to the embodiment of the utility model can be assembled by connecting the first folded edge 12 and the second folded edge 22 stacked together to assemble the first half-bend pipe 1 and the second half-bend pipe 2, which reduces the installation difficulty, facilitates installation, makes the connection more stable and reliable, and improves the protection effect of the elbow outer protective shell.
[0036] like Figures 1 to 5 and Figure 7 As shown, in some embodiments, the first folded edge 12 is provided with a first connecting through-hole 13; the second folded edge 22 is provided with a second connecting through-hole 23 corresponding to the first connecting through-hole 13. Specifically, the first folded edge 12 is provided with a plurality of first connecting through-holes 13, and the plurality of first connecting through-holes 13 are spaced apart along the extension direction of the first folded edge 12. The second folded edge 22 is provided with a plurality of second connecting through-holes 23, and the plurality of second connecting through-holes 23 are spaced apart along the extension direction of the second folded edge 22. Preferably, the plurality of first connecting through-holes 13 correspond one-to-one with the plurality of second connecting through-holes 23.
[0037] like Figure 5 and Figure 7As shown, in some embodiments, the first folded edge 12 and the second folded edge 22 are connected by fasteners passing through the first connecting through-hole 13 and the second connecting through-hole 23. Specifically, the fasteners may be bolts. The first folded edge 12 and the second folded edge 22 are connected by bolts passing through the first connecting through-hole 13 and the second connecting through-hole 23. That is, after the first half elbow 1 and the second half elbow 2 are enclosed together, they are connected by a plurality of bolts passing through the corresponding first connecting through-holes 13 and the second connecting through-holes 23.
[0038] like Figure 6 As shown, the first folded edge 12 and the second folded edge 22 can be connected by welding. Specifically, after the first half elbow 1 and the second half elbow 2 are enclosed together, the first folded edge 12 and the second folded edge 22 are overlapped and then welded.
[0039] In some embodiments, the first half elbow 1 can be integrally stamped from a thin sheet, and the first half elbow 2 can be integrally stamped from a thin sheet. Specifically, a fixture is used to clamp the two edges of the thin sheet, and then the sheet is stamped using a die to form the half elbows, with the portion clamped by the fixture forming a hem. For example, the first half elbow 1 and the first half elbow 2 can both be integrally stamped from a metal sheet, with the first hem 12 forming a substantially 90° angle with the body of the first half elbow 1, and the second hem 22 forming a substantially 90° angle with the body of the second half elbow 2. In related art, because half elbows lack hems, securing the sheet during stamping is difficult, and controlling the forming process during the die stamping process is difficult, resulting in complex assembly. In the present embodiment, the first and second half elbows are provided with hems, which can be used for clamping during processing, facilitate die stamping, and simplify manufacturing. Furthermore, the hems serve to connect the first and second half elbows, resulting in easy assembly of the elbow outer casing, reliable connection, and effective protection.
[0040] In some embodiments, the thickness of the thin plate is 0.2-2 mm, for example, the thickness of the thin plate is 0.5 mm, 1 mm, or 1.5 mm.
[0041] In some embodiments, the first half of the curved tube 1 and the second half of the curved tube 2 are symmetrical. Specifically, the first half of the curved tube 1 and the second half of the curved tube 2 are semicircular tubes, so that when the first half of the curved tube 1 and the second half of the curved tube 2 are combined, they form a circular tube. For example, the inner and outer cross-sectional profiles of the first half of the curved tube 1 and the second half of the curved tube 2 are both semicircular arcs. This allows for easy processing and excellent interchangeability of the first and second half of the curved tube, reduces manufacturing costs, and simplifies assembly.
[0042] like Figure 8As shown, the thermal pipeline of the present embodiment includes a thermal pipe 3, an insulation layer 4 covering the outside of the thermal pipe 3, and an elbow outer shell. The thermal pipe 3 has a bend section, and the elbow outer shell is wrapped around the insulation layer 4 outside the bend section. The elbow outer shell is the elbow outer shell 100 of the above-mentioned embodiment.
[0043] Therefore, according to the thermal pipeline of the embodiment of the present invention, the elbow outer protective shell 100 is easy to install, has a reliable connection, and has a good protection effect on the insulation layer.
