摘　　要：介绍一种带压差控制的超高压气动吹除阀及其工作原理。运用AMESim气动元件设计库建立吹除阀仿真模型,对其动态特性进行系统的分析研究,并进一步探究主阀阀芯节流孔孔径、控制阀弹簧预压缩量、气源压力、舷外海水压力等参数对吹除阀吹除性能的影响。最后,对吹除阀的性能进行实验研究。研究结果表明:吹除阀的工作性能平稳,响应灵敏,压差控制精度高;气源压力、舷外海水压力对吹除阀压差控制性能没有影响,但提高气源压力或降低舷外海水压力能够有效提高吹除效率;通过改变节流孔孔径与控制阀弹簧预压缩量,可以调节吹除阀压差控制范围。In this paper, a type of high pressure pneumatic blowing valve with differential pressure controldevice is presented, and the valve＇s working principle is introduced. The simulation model of the valve is es-tablished using AMESim pneumatic components library, and the dynamic characteristic of the valve is sys-tematically analyzed. The respective effects of the main valve spool＇s orifice aperture, the valve＇s pre-com-pressed spring length, air source pressure, and seawater pressure on the valve＇s performance are further in-vestigated. Finally, the experimental study of the valve＇s performance is carried out. The research resultsshow that the performance of the valve is stable with sensitive response and precise differential pressurecontrol; increasing the air source pressure or reducing the seawater pressure can effectively improve theworking efficiency, while the change of these two parameters has no impact on the differential pressure con-trol precision; The range of differential pressure control can be modified by changing the main valve spool＇sorifice aperture and the control valve＇s pre-compressed spring length.
