Design and Magnetic-circuit Modeling of a Novel Limit-type Solenoid Valve Considering Magnetic Saturation
摘要
Abstract
A novel limit-type solenoid valve structure is proposed to address the issues of overheating and low efficiency in traditional limit-type solenoid valve under continuous power operation.An accurate magnetic-circuit modeling method considering magnetic saturation effects is established.By analyzing and accounting for core saturation at the stator tip and the central hole,the precision of the theoretical mathematical model is significantly enhanced.Finite element simulation and experimental platform testing are employed to systematically verify the structural performance and magnetic force output.The results indicate that the limit-type solenoid valve model,which considers saturation effects,achieves a high degree of fit with the simulation curve within a stroke range of 0～10 mm,with a maximum relative error of only 5.86％,representing a substantial improvement in computational accuracy compared to traditional models.Moreover,the design maintains attractive force performance while significantly reducing copper power consumption to only 19.9 W,approximately 75％lower than existing limit-type solenoid valve structures,demonstrating excellent thermal stability and continuous operation capability.This study provides theoretical support and engineering design references for electromagnetic valve structures intended for low-speed,long-duration operation scenarios.关键词
