Description

Technical Field

[0001] The utility model relates to the technical field of metal hoses, in particular to a metal hose with a thermal insulation sleeve. Background Art

[0002] Some pipes exposed to the air may be damaged and cracked due to long-term exposure to natural conditions such as sun and rain, causing gas or liquid leakage in the pipes. Especially when the temperature is relatively low, the equipment may even be frozen and cracked. Once leaked, it will cause harm to people and pollute the surrounding environment. For this reason, insulation sleeves are generally installed on the outside of the pipes. Therefore, a metal hose with insulation sleeves is proposed.

[0003] In the existing technical scheme, a double-layer metal hose for gas pipelines is proposed with publication number: CN217130584U, which belongs to the technical field of metal hoses for gas pipeline transmission, including an integrally arranged threaded outer layer and a threaded inner layer, an armor belt is arranged on the inner wall of the threaded outer layer, an inner sleeve is arranged on the inner side of the threaded outer layer, a buffer strip is arranged between the inner sleeve and the threaded inner layer, anti-slip protrusions are arranged on the surface of the inner sleeve, reinforcing ribs are arranged inside the anti-slip protrusions, and an insulating filling layer is arranged between the inner sleeve and the threaded outer layer and the threaded inner layer.

[0004] In order to solve the problem that the previous metal hose cannot meet the high pressure resistance, high temperature resistance and good anti-puncture protection during gas transmission, the existing technology is to use an armor belt on the inner wall of the threaded outer layer, the surface of the threaded outer layer is a concave arc structure, and the surface of the armor belt is a convex arc structure, such as Figure 2 According to the principles of mechanics, when the outer surface of the thread is pressed by external force, the outer surface of the thread continues to sink inward, forcing the distance between the two sides of the outer layer of the thread to decrease, and the two sides of the outer layer of the thread tighten inward, thereby pressing the internal armor belt to bend and bulge upward. The armor belt then supports the outer layer of the thread to continue to sink downward. However, the thermal insulation function of the pipeline is poor, resulting in heat loss of the medium in the pipeline and a high temperature on the outside of the metal hose, which in turn causes burns to the staff.
