弹簧支吊架

Metal bellows expansion joint consist oftwo multi-convoluted bellows connected with an intermediate pipe into one assembly. Allows all three movements: axial, lateral and angular simultaneously.

The Metal bellows expansion joint consists of two bellows separated by a pipe section or spool. The primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. The amount of lateral deflection they can accept is a function of the amount of angulation each bellows can absorb and the distance between the bellows. For a given bellows element, the amount of lateral deflection capability can be increased or decreased by simply changing the length of the center spool.
