72 Fluid-Solid Coupled Performance Analysis and Optimization of Spindle Type Check Valve Based on Adina Available to Purchase

Spindle type check valve is the most important part of piping inactive technology, and can automatically achieve the pipeline system security role by no human or plus driving. Then it can effectively reduce the infusion pipeline accident's occurrence. Based on ADINA, large diameter spindle type check valve is focused on fluid-solid coupling numerical analysis. Fluid-solid coupling finite element model of the spindle type check valve can be established, and then pipe flow field for dynamic analysis is to be done. At last, numerical simulation results are introduced in detail. According to the results of analysis, an optimized scheme for the spindle type check valve structure design will be provided.
