基于ANSYS的给水泵最小流量调节阀结构优化OA

Under high temperature and high pressure working conditions,the internal medium of the minimum flow control valve is prone to flash evaporation and cavitation,which can easily lead to the erosion of the surface material of the valve body components and reduce the service life of the valve.In order to effectively solve this technical problem,based on the fluid control principle of multi-stage eddy current pressure reduction structure,systematic optimization is carried out on the key components in the valve through the improvement scheme combining structural innovation and material optimization,including:adding the regulating valve head,surfacing STL at the spool head,adding the imported porous valve seat,and re-selecting the materials of the main components in the valve.The simulation analysis on ANSYS Fluent of the improved valve is carried out,and the results show that the internal flow velocity field distribution of the optimized minimum flow control valve is more uniform,flow speed of the medium inside the flow control valve is stable around 1.12×103 m/s,and the step-by-step pressure reduction capacity is improved,secondary grade pressure at the optimized valve core is only 50%among the maximum pressures of the first four grades,which effectively improved the flow control and energy-saving performance,and provides a reliable guarantee for the long-term safe operation of industrial equipment.
