    摘要:

    随着数字液压技术的发展,对高速开关阀的性能有了更高的要求,高速开关阀阀芯力学特性决定了其整体性能。建立了某高速开关阀的CFD模型。针对不同工作压差、不同工作温度、不同底座孔径、不同底座角度以及不同开口度的某高速开关阀内部流场速度场进行了分析。分析不同工况下某高速开关阀阀芯液压力影响因素,进一步研究了阀口开度、阀口形状、阀口压差、油液温度对该阀芯液压力的影响规律,为高速开关阀设计提供了理论基础。

    Abstract:

    With the development of digital hydraulic technology, performance of the high speed on-off valve have higher requirements, the mechanical properties of high speed on-off valve spool determine the overall performance. The Computational Fluid Dynamics (CFD) model of a high speed on-off valve is established. According to the different working pressure, different temperature, different base diameter, different base angle and different opening of a high speed on-off valve, internal flow velocity field was analyzed. The factors that affect the hydraulic pressure of high speed onoff valve were analyzed under different working conditions. The affecting law of valve opening, the valve outlet shape, valve opening pressure, oil temperature on the hydrauic pressure of valve spool is further researched to provide a theoretical basis for the design of high-speed onoff valve.
