这里介绍的是一种较特殊的叠层式金属波纹管。它由一些圆片组成,这些圆片通常是带有中心孔的环状物,这种形状便于圆片间的相互连结,那就是两个圆片的相邻外缘相连结,而另一边和另一个圆片的内缘相连结。这里所叙述的叠层式膜片金属波纹管,在外缘和中心孔边缘部份都是牢固连结在一起的,而中间部份都是彼此啮合而不是固定死的。这种形式的波纹管,其内外均有耐压能 Here is a more special type of laminated metal bellows. It consists of a number of wafers, which are usually rings with a central hole that facilitates the interconnection of the wafers, where adjacent wafers of the two wafers are joined and the other The inner edge of the other wafer is joined. The laminated diaphragm metal bellows described here are firmly joined together at the rim and at the edge of the center hole, with the middle portions engaging each other rather than dead. This form of bellows, both inside and outside pressure energy
