Structure optimization design and simulation of a directoperated solenoid valve

以一种通径为10 mm的直动式电磁阀为例,在外部接口和流道结构相同的前提下,优化设计引入先导式电磁阀的设计思想,通过在阀芯设置引流导管,引入内部高压燃气,辅助打开主阀,大幅减小了阀芯开启所需的电磁力,降低了电磁铁功耗和产品重量。结构优化后电磁阀额定功率降低为原方案的25.1%、最大工作压强提升为原方案的1.6倍。并进行了隔热结构优化设计和仿真,使电磁阀极限工况下电磁铁最高温度降低130.4℃,使该类电磁阀的综合性能指标大幅提升,为类似产品的优化设计提供了参考和依据。

Taking a direct operated solenoid valve with 10 mm diameter as the research object,under the premise of the same external interface and flow path structure,the design idea of a pilot-actuated solenoid valve was introduced.By putting a drainage catheter in the valve core,the internal high-pressure gas was introduced to help open the main valve,which greatly reduced the electromagnetic force required for valve open,and reduced the electromagnet power consumption and product weight.After the structural optimization,the rated power of the solenoid valve was reduced to 25.1%of the original scheme,and the maximum working pressure increased to 1.6 times that of the original scheme.The optimization design and simulation of the thermal insulation structure were carried out,and the maximum temperature of the solenoid valve under the limit working conditions was reduced by 130.4℃.The comprehensive performance of the solenoid valve is greatly improved.This study has provided reference and basis for the optimization design of similar products.
