The invention provides an ultralow-temperature and ultra-vacuum aluminum-magnesium alloy sealing ring. The aluminum-magnesium alloy sealing ring comprises a sealing ring body made of an aluminum-magnesium alloy, wherein the sealing ring body is circular; the section of the sealing ring body is a regular hexagon which comprises six edges; sealing and cutting edges are arranged on the sealing ring; the sealing and cutting edges are linear cutting edges; the number of the sealing and cutting edges is two; the two sealing and cutting edges are arranged at opposite angles of two ends of the sealing ring body; the two sealing and cutting edges are distributed in an axial symmetry manner by taking the section of the sealing ring body as a reference surface. The ultralow-temperature and ultra-vacuum aluminum-magnesium alloy sealing ring is free of damage to a device interface flange, convenient to mount and high in cost performance; the sealing ring is widely used for connecting and sealing vacuum parts under low-temperature, ultralow-temperature and normal-temperature conditions; the application range is widened; the product using effect is improved.
Description
technical field [0001] The invention relates to an ultra-low temperature and ultra-vacuum aluminum-magnesium alloy sealing ring, which is used for connection and sealing between vacuum components in an ultra-low temperature and ultra-vacuum working environment. Background technique [0002] The vacuum system is composed of various components such as vacuum equipment, flanges, and pipes through different connection forms, and is also composed of multiple components and components of various materials. These various parts need to be connected together with different sealing methods. These sealing methods must not only ensure the reliable connection of the parts but also prevent air leakage through the interface. In order to ensure the sealing quality of the vacuum system, the air leakage of the vacuum system The efficiency is controlled within a certain range, so the vacuum sealing ring is an important issue in the design and assembly of the vacuum system. The general sealing...
