The invention relates to the field of fluid delivery equipment and particularly discloses a high-pressure rotating joint. The main technical problems that compressed natural gas only can be loaded and unloaded through a hose, and a steel pipeline cannot meet the use demands of high pressure gas or fluid equipment due to severe strength deficiency caused by the structural defects of common rotating joints in the prior art are solved. The high-pressure rotating joint comprises a flange gland, an outer shell, an inner shell, an inn ring and a sealing device, wherein the flange gland is arranged at one end of the high-pressure rotating joint; one end of the outer shell is connected with the flange gland; the inner shell is arranged at the inner side part of the outer shell, and a cavity I is formed between the inner shell and the outer shell; the inner ring is arranged in the cavity I, and at least two rollaways are arranged between the inner ring and the outer shell; and the sealing device is arranged between the opposite end surfaces of the inner shell and the flange gland. The high-pressure rotating joint is high in structural strength, can realize mutual rotating and mutual sealing, can be used on high pressure gas or fluid equipment and has high popularization and use values.
Description
technical field [0001] The invention relates to the field of fluid delivery equipment, in particular to a high-pressure rotary joint. Background technique [0002] With the application of clean energy more and more widely, natural gas has been recognized by more and more people as a new type of clean energy, and more and more vehicles use natural gas as energy. The demand for loading and unloading devices for compressed natural gas is also increasing. Since the pressure of compressed natural gas is as high as 25MPa, there is a risk of rupture and explosion in storage devices and pipelines. At the same time, natural gas itself is also a flammable and explosive product, which has the risk of combustion and explosion. At present, all over the world, the loading and unloading devices of compressed natural gas use hoses. However, the use of hoses has the following disadvantages: 1. There is no qualified and first-class hose manufacturer in China, so the hoses of domestic natura...
