ANSI法兰的密封原理极其简单：螺栓的两个密封面相互挤压法兰垫片并形成密封。
ANSI flange sealing principle is extremely simple: the two bolts each other extrusion flange sealing surface and form a seal gasket.
而且，从根本上来说，ANSI法兰是壹种无效的密封，它需要把50%的螺栓负荷用于挤压垫片，而用于保持压力的负荷只剩50%。
And, essentially, is one kind of invalid ANSI flange sealed, it needs to put 50% of the bolt load for dummy blocks, and to be used for pressure load of only 50%.
