Abstract: The pressure drop of a control valve is directly associated with the energy consumption of the control system. The conventional design method of a control valve results in high energy consumption, while the control ability deviates from the design goal. Additionally, repeated corrections via flow experiments are inefficient. To efficiently design a low-energy-consumption control valve that satisfies control requirements, a novel design method is proposed herein. It is parametrically defined in Sculptor software based on the conventional valve spool. Various software packages are integrated using script files in the Isight platform. An approximate model is constructed using sample points generated based on the design of experiments; subsequently, it is solved using an optimization algorithm. Simulation results indicate that the output pressure of the pump and the average pressure drop of the control valve decrease by 4.38% and 5.51%, respectively, under the same flow rate. The working flow characteristics curve exhibits high linearity, implying that energy conservation is realized while the control ability is improved. Moreover, the force on the valve spool decrease by 1.36% on average, while the pressure and velocity in the flow field are reduced.
