英文摘要	In view of the transient dynamic analysis in opening swing check valve, the motion model of valve clack is built, two-dimensional dynamic numerical simulation of the internal unsteady flow is performed by using dynamic mesh and UDF in opening two kinds of swing check valve at the same working condition, the visualized results are obtained. The results show that internal flow field of the modified model become more stable, the noise, impact and the local energy loss are decreased, the service life is improved obviously; an important reference for swing check valve design and analysis of dynamic characteristics are provided by the research results. © (2013) Trans Tech Publications, Switzerland.
