法兰 名字的由来.

     其名字是来源于英文flange，  法兰盘简称法兰，只是一个统称，通常是指在一个类似盘状的金属体的周边开上几个固定用的孔用于连接其它东西。这东西在机械上应用很广泛，所以样子也千奇百怪的，只要像就是叫法兰盘。

The flange or flanges, just a collectively, usually refers to a similar disc shaped metal body arranged around several fixing holes for connection to other things. It is widely used in machinery, so it is all sorts of strange things, just like is called flange, its name is derived from the English flange.
