Abstract

As the development basis for the intelligent integration period of Industry 4.0, high speed on-off valves are widely used in fields such as aerospace, vehicles, and construction machinery. The flow and pressure characteristics of high speed on-off valves under different electromagnetic drive forms are different. According to different electromagnetic drivers, high speed on-off valves can be divided into moving coil type high speed on-off valves (MCTHSV) and moving iron type high speed on-off valves (MITHSV). At present, there is almost no comparative analysis of the characteristics of the valves, and the difference between the response characteristics have not been quantified. In order to compare the response characteristics more accurately under the same coil parameters, this paper uses a combination of finite element analysis and hydraulic simulation analysis to analyze and discuss the two types of valves. First, the principle analysis and mathematical modeling are carried out. Then, the valves is simulated using Ansys and Amesim. By analyzing the characteristics of flow and pressure and opeing time under pulse width modulation (PWM), the superiority of the MCTHSV is obtained accurately. When the mass of the moving part of MCTHSV is 20g, its opening time is 2.74ms, while the opening time of MITHSV is 4.37ms. It provides ideas for the optimization, analysis and selection of high speed on-off valves.
