Proposed a set of parametric design methods and computational simulation models for the solenoid valve solenoid head coil to calculate the minimum electromagnetic force required to drive the solenoid valve to open and close and the thermal equilibrium temperature that can be achieved when the solenoid coil is energized fora long time.The available range of parameters was explored from three dimensions:electromagnetic structure design,temperature balance analysis,and comprehensive performance optimization,and the optimal solution for comprehensive performance was obtained.At the same time,two sets of coils were actually wound to measure the electromagnetic force and thermal equilibrium temperature.The applicability of the analytical model was proved by the test comparison,and the optimal design of the electromagnetic coil was verified.Based on the method and model proposed in this paper,the design,manufacture and performance test of the prototype safety-level solenoid valve for scientific research have been completed.
