bellows structure according to many aspects, such as corrugated shape, layer number of bellows, preliminary assessed whether to and other elastic element combination, the ends of the corrugated pipe end, whether the structure type

to guide and so on. 1 choice of corrugated shape: according to the requirements of the corrugated tube use, performance, use, and various factors such as performance and manufacturing characteristics of waveform to choose reasonable corrugated shape. In general,

most choose u-shaped bellows, etc. Determine the corrugated pipe layer 2: according to the purpose of the bellows, job stress, stiffness, layer number of factors such as working medium to determine the bellows. Under the condition of the working pressure is higher, generally selected layers '

structure of bellows, rationally choose for multilayer bellows need layer and single layer thickness. 3 preliminary assessed whether to and other elastic element combination: in some cases corrugated pipe and spiral spring in parallel to use, these case are respectively: in order to improve the accuracy of measurement; Working pressure higher

occasion; There are impact load. 4 choose the end both sides of the corrugated pipe structure: choose the end both sides of the corrugated pipe structure, want to consider to both ends of the structure of the forming process, welding process and the whole system in the aspect of structure of

restrictions. May consider whether you need to guide: when bellows effective length is longer, in order to avoid in the process of our work columnar instability, should consider to increase the guide. Valve with corrugated pipe, for example, a

as a guide device. Considering whether to need to strengthen ring: in order to adapt to the demand of high working pressure, corrugated pipe can be used to strengthen ring to strengthen, or USES the multilayer structure, can also be used a combination of these two kinds of structure.

strengthening ring is local, multilayer structure to strengthen the whole.
