Abstract:
The mechanical structure and working principle of a pilot-operated diaphragm solenoid valve are introduced. A mathematical model for coupling of multi-physical processes is set up. The AMESim-based dynamic simulation model of the pilot-operated solenoid valve is built. The influences of throttling orifice, work pressure, spring stiffness and spring force on the dynamic response characteristics of the pilot-operated diaphragm solenoid valve are analyzed. The results show that throttling orifice has a great influence on the response time of the pilot-operated diaphragm solenoid valve, and the opening response time prolongs and the close response time decreases with increase of the throttling orifice. The method in this paper can be applied to the design and analysis of pilot-operated solenoid valve, and has a certain value in engineering application.
