Abstract

By computational fluid dynamics (CFD) technology, the numerical simulation of internal flow field for pilot operated check valve is determined. In the paper, by building flow channel model under different valve opening and changing its import and export pressure, it gets the pressure distribution contour and velocity vector distribution. Analyzing the result, it is found that the corner valve port of low pressure is serious and flow field reach maximum speed. It is easy to produce cavitation, noise and shock. Improved the flow structure and compared cavitation index curve, it is found the cavitation index increases, which can reduce the possibility of cavitation.
