Simulation and Analysis the Internal Flow Field of Control Valve Bonnet Leakage

Abstract:

Apply the CFD numerical simulation the internal flow field and noise when the control valve is bonnet leakage and trouble-free. Research shows that bonnet leaking has almost no effect on valve inlet and outlet flow field. It is an impact on valve body flow field and the greatest impact on balance cavity. It changes the flow direction of the balance cavity and produces right vortex, in balance cavity where originally without noise, the tremendous noise appeares and improves the noise of the surrounding area.
