Optimum Design Of The Structure Of The Throttle Pipe Pattern Control Valve Based On FLUENT

The control valve has been widely applied to nuclear power industry, and it is the importantcontrol components in fluid carrying system. The request of control valve is very high for theNuclear power plant, not only to ensure the quality of regulation, but also to reduce the energyconsumption of flow. Due to complicated inside structure of control valve, to researchmechanical performance of the control valve on the view of hydrodynamics has tremendouslysignificant to reducing power loss and improving energy efficiency.Along with the development of computer technology and computational fluid dynamics(CFD), numerical simulation has become a primary method to research the internal flow andthe performance of hydro-machinery. In this paper, the solid model of the throttle pipe patterncontrol valve was built by Pro/ENGINEER software, and the valve was dependent researchedby Harbin Engineering University, extracting the channel of the valve by Pro/ENGINEERand meshing the channel by the pre-processing software ICEM CFD. By the application ofthe CFD software FLUENT, a three-dimensional numerical simulation was performed of theinternal flow field of the valve, and we got the distribution of the pressure of the valvesystems and the motor power of the valve by second computing. Optimizing the valvechannel, by contrasting and analyzing the power consumption of the electrical appliances todifferent channels of the valve, we got the more ideal runner structure of the control valve.The research results of this paper provide the criterion for improving and optimizing thethrottle pipe pattern control valve, besides that, it also found the basis for deeperinvestigation.
