Description
Technical field
The utility model is related to a kind of expansion joint, particularly a kind of Novel hinge type bellows expansion joint.
Background technology
Expansion joint is traditionally also compensator, or telescopic joint.By the bellows for constituting its operative body（A kind of elasticity unit
Part）Constituted with the annex such as end pipe, support, flange, conduit.Expansion joint be to compensate for because temperature difference and mechanical oscillation cause it is attached
Plus stress, and it is arranged on a kind of flexible structure on container casing or pipeline.Using the effectively flexible of its operative body bellows
Deformation, with the change in size that absorption line, conduit, container etc. are produced by the reason such as expanding with heat and contract with cold, or compensation pipes, conduit,
The axial of container etc., transverse direction and angular displacement.Can also be used for noise-and-vibration-reduction, in heat supply, during in order to prevent heat supply pipeline from heating up, by
Cause pipe deforming or destruction in thermal stretching or temperature stress, it is necessary to set compensator on pipeline, to compensate the heat of pipeline
Elongation, so as to reduce the stress of tube wall and act on the active force on valve member or supporting structure.
The most of bellows expansion joints for now using, are to set multiple protection pull bars on periphery, in actually used mistake mostly
Cheng Zhong, hence it is evident that have that stress compensation effect is poor, structure fragile situation.
