Description

Technical Field

[0001] The utility model belongs to the technical field of metal hoses, in particular to a liquid oxygen metal hose. Background Art

[0002] Liquid oxygen is the form of oxygen in liquid state. It has important applications in aerospace, submarines and gas industries. Liquid oxygen is a light blue liquid with strong paramagnetism. Metal hoses are required for the transportation of liquid oxygen. Metal hoses are installed in liquid transportation systems as a flexible pressure-resistant pipe fitting to compensate for the mutual displacement of the connection ends of pipelines or machines and equipment, absorb vibration energy, and can play a role in vibration reduction and noise reduction. They have many advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.

[0003] For example, the Chinese patent with publication number CN205479803U discloses a liquid oxygen and nitrogen resistant ultra-low temperature metal hose, including a metal hose body, on which a pressure-resistant layer, a thermal insulation layer, and a protective layer are arranged; a vacuum layer is arranged between the thermal insulation layer and the pressure-resistant layer; a thermal insulation sponge is arranged in the vacuum layer; the protective layer is made of stainless steel; and the pressure-resistant layer is made of ultra-low temperature steel.

[0004] The above patent has the following problems:

[0005] Compared with the existing technology, the metal hose has a single high-temperature resistant material, which cannot transport liquid oxygen well. Long-term use will damage the hose, and the liquid oxygen cannot be transported in time, which increases the working time of liquid oxygen and reduces the working efficiency of liquid oxygen transportation. In addition, the protective cover of the hose in the existing technology is only made of stainless steel, which is a single material type and cannot protect the hose well. It is very susceptible to oil stains and dust, which is not aesthetically pleasing. In addition, there is no high-temperature resistant material, which cannot protect the metal hose well. In view of this, we propose a liquid oxygen metal hose. Utility Model Content
