The invention discloses a micro-compensation end face flange, which comprises a first toroidal surface connected with an outer wall of a vacuum pipe inner pipe, and a second toroidal surface connected with an outer wall of a vacuum pipe outer pipe. The first toroidal surface is smoothly transited through a first arc-shaped surface so as to be connected with a toroidal connecting surface; the second toroidal surface is smoothly transited through a second arc-shaped surface so as to be connected with the toroidal connecting surface; and a sealed vacuum chamber is formed among the outer wall of the vacuum pipe inner pipe, the vacuum pipe outer pipe, the first toroidal surface, the first arc-shaped surface, the toroidal connecting surface, the second arc-shaped surface and the second toroidal surface. The flange is reasonable in structure arrangement, and can effectively seal and insult the vacuum pipe inner and outer pipes, and the flange with the structure is combined with the vacuum pipe so as to have a certain stress compensation function and effectively meet the requirement on high vacuum multilayer insulation for cold insulation, so that the cold loss is controlled to the minimum, and the use value of an energy medium is effectively improved to the maximum.
Description
technical field [0001] The invention relates to the field of connectors, in particular to a flange structure used for the sealed connection of vacuum tubes and having a certain compensation function. Background technique [0002] In the field of cryogenics, for flammable and explosive gases, high-purity gases, cold source gases, etc., in order to avoid loss and harm to the environment, non-destructive storage is often used for storage and transportation. High-vacuum multi-layer insulation cryogenic liquid pipeline (hereinafter referred to as high-vacuum pipeline) has been widely used in the field of low-temperature storage and transportation due to its excellent thermal insulation performance, involving machinery, petrochemical, metallurgy, biology, medical, aerospace and many other industries . At present, the development and process research of domestic high-vacuum multi-layer insulation technology is on the rise, but most of the high-vacuum pipeline connection joints hav...
