Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a glass wool pipeline insulation shell. Background Technology

[0002] Glass wool pipes are a type of insulation material widely used in the construction and industrial fields. They are mainly made of cotton-like material produced by molten glass fiberization, which is then processed into tubular products.

[0003] Its main characteristics are low thermal conductivity and excellent thermal insulation performance, which can effectively reduce heat or cold loss in piping systems and significantly save energy. At the same time, it has excellent sound absorption and noise reduction properties, improving environmental comfort. The material is a Class A non-combustible material with high fire safety performance. Furthermore, it is chemically stable and has characteristics such as corrosion resistance and mildew resistance.

[0004] Glass wool pipes consist of a core insulation layer and a facing layer. The core insulation layer is a tubular porous material formed by fiberizing molten glass and then curing it with an adhesive. It is filled with numerous tiny air pores, resulting in extremely low thermal conductivity and effectively blocking heat transfer. However, in practical use, glass wool insulation structures are not resistant to impacts and foot traffic. In environments requiring load-bearing capacity or susceptible to external impacts, it is prone to compression and deformation, leading to a decrease in insulation performance. Furthermore, the porous structure of glass wool is susceptible to moisture, which severely damages its insulation performance, and continuous dampness can cause corrosion of the metal pipes it wraps. Therefore, there is room for technological improvement. Utility Model Content

[0005] This invention aims to solve the aforementioned technical problems of poor compressive strength and susceptibility to moisture, which leads to corrosion of the encased pipes, by providing a glass wool pipe insulation shell.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a glass wool pipe insulation shell, including a glass wool sleeve; a plurality of protective tubes are detachably provided on the outside of the sleeve, and adjacent protective tubes can be spliced ​​together;

[0007] The protective tube includes an arc-shaped plate one and an arc-shaped plate two hinged on one side. The arc-shaped plate one and the arc-shaped plate two are provided with fixing ears on the side away from the hinge and near both ends. Each fixing ear is provided with a through hole, and the through holes are connected by bolts and nuts.

[0008] The sleeve includes a core layer and an outer sheath. The outer sheath has several ribs arranged circumferentially on its outer side, and the cross-section of each rib is semi-circular.

[0009] Furthermore, each of the protective tubes has an annular limiting protrusion at one end and a limiting groove at the other end that can accommodate the limiting protrusion; the arc plate one and arc plate two are respectively provided with a rectangular insert and a slot on the side away from the hinge.

[0010] Furthermore, both the first and second arc-shaped plates are provided with pads on their inner sides; the cross-sections of both the first and second arc-shaped plates are semi-circular.

[0011] Furthermore, the ribs are made of vulcanized rubber and have a wear-resistant sand coating on their surface.

[0012] Furthermore, a mesh cover is provided between the core layer and the outer sheath, and the mesh cover is connected and fixed to the core layer and the outer sheath by an adhesive.

[0013] Furthermore, adjacent protective tubes are reinforced with adhesive between them and outside the limiting protrusions and limiting grooves.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] Several protective pipes can be freely spliced ​​and installed on the outside of the casing. They can be installed at the stress position of the casing or evenly spaced to cover the outside of the casing, which can greatly improve the structural strength and pressure resistance of the glass wool pipe and make it highly practical.

[0016] Several ribs are provided on the outside of the sleeve to improve wear resistance, so that it is in direct contact with the ground. This can prevent the surface of the sleeve from being damaged due to friction, thus affecting the heat preservation effect. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, in conjunction with Appendix Figure 1 , 2 3. A glass wool pipe insulation shell, including a glass wool sleeve 1, which is fixed to the pipe to be insulated during use to achieve protection and insulation effects.

[0025] Several protective tubes 2 are detachably provided on the outside of the sleeve 1. Adjacent protective tubes 2 can be spliced ​​together. In actual use, the protective tubes 2 provide further protection for the sleeve 1 in the stress section or water immersion section, thereby improving the compression resistance of the sleeve 1. Specifically, each protective tube 2 has an annular limiting protrusion 3 at one end and a limiting groove 4 at the other end that can accommodate the limiting protrusion 3. The arc plate 1 5 and arc plate 2 6 are respectively provided with a rectangular insert 13 and a slot 14 on the side away from the hinge. The positioning and initial connection of adjacent protective tubes 2 are achieved through the annular limiting protrusion 3 and the limiting groove 4, as well as the insert 13 and the slot 14, thereby enhancing the overall structural strength.

[0026] Based on the above, adjacent protective tubes 2 are reinforced with adhesive outside the limiting protrusion 3 and the limiting groove 4 to further improve the connection strength of adjacent protective tubes 2;

[0027] Combined with appendix Figure 1 , 2 3. The protective tube 2 includes an arc-shaped plate 5 and an arc-shaped plate 6 hinged on one side. The cross-section of the arc-shaped plate 5 and the arc-shaped plate 6 is semi-circular. The arc-shaped plate 5 and the arc-shaped plate 6 are provided with fixing ears 7 on the side away from the hinge and near both ends. Each fixing ear 7 is provided with a through hole, and the through holes are connected by bolts and nuts. The fixing ears 7, bolts and nuts enable the quick assembly and disassembly of the arc-shaped plate 5 and the arc-shaped plate 6, which is convenient for operation.

[0028] Combined with appendix Figure 2 , 3 Both the inner sides of the arc plate 1 (5) and the arc plate 2 (6) are provided with pads 8. The pads 8 are made of flexible material. When installed on the outside of the sleeve 1, they can avoid damage caused by hard compression and stress concentration.

[0029] Example 2, in conjunction with Appendix Figure 1 , 45. The sleeve 1 includes a core layer 9 and an outer protective layer 10. Several ribs 11 are provided on the outer side of the outer protective layer 10 along the circumference. The cross-section of each rib 11 is semi-circular. The ribs 11 are evenly arranged on the outer side of the sleeve 1 along the length direction to improve the structural strength of the sleeve 1. The ribs 11 are made of vulcanized rubber and have a wear-resistant sand coating on the surface. Since the ribs 11 protrude from the sleeve 1, when the protective pipe 2 is not installed, the ribs 11 are in contact with the external equipment or the ground first, which can isolate the ground moisture and water layer. The wear-resistant sand coating can improve the wear resistance of the ribs 11 and make them more durable.

[0030] In addition, a cover net 12 is provided between the core layer 9 and the outer sheath 10. The cover net 12 is connected and fixed to the core layer 9 and the outer sheath 10 by an adhesive. The cover net 12, with its multi-mesh structure, can increase the contact area between the adhesive and the core layer 9 and the outer sheath 10, making the connection stable and also providing further protection for the core layer 9.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
