【Abstract】 This paper studied the dynamic analysis of the relief valve, the AMESim model of relief valve was built by using lumped parameter method. The dynamic analysis and the influence of key parameters for valve property were studied. The three-dimensional model of the valve flow was built, the CFD numeric analysis of relief valve at different opening degrees was carried out. In this paper, the dynamic analysis of the relief valve with shield device or release pipe was studied. The results realized the quantitative dynamic analysis of relief valve property.更多还原
