本文对CONFLAT密封中存在的一些问题做了分析。讨论了CONFLAT密封中产生径向变形的影响,提出了密封垫改进的方法,使CONFLAT密封性能得到明显的改善。一、CONFLANT密封的优缺点在高和超高真空系统中,应用的金属法兰,为数众多的还是CONFLAT(不锈钢刀口法兰与无氧铜垫)密封。这种密封是在法兰上加工有70°刀口压紧金属垫,随着刀口切入垫达到一定深度,而获得密封。这种结构通常可获得十分低的泄漏率(10~(-10)托升/秒以下)。密封可靠,可耐450℃温
This article analyzes some of the problems with CONFLAT seals. The influence of radial deformation in CONFLAT seal was discussed. An improved method of gasket was proposed to improve the sealing performance of CONFLAT obviously. First, the advantages and disadvantages of CONFLANT seal In the high and ultra-high vacuum system, the application of the metal flange, a large number or CONFLAT (stainless steel blade flange and oxygen-free copper pad) seal. This seal is processed in the flange with 70 ° knife blade pressed metal pad, with the knife into the pad to a certain depth, and get a seal. This structure usually achieves a very low leakage rate (below 10 -10 Torr / sec). Sealed and reliable, resistant to 450 ℃ temperature
