本文简要介绍了消除和减小滑阀轴向液动力和径向力的几个方法并列举一种减小液动力和径向力的电气流量控制阀应用实例。尤其是采用了重量轻的铝质空心阀芯并在阀芯上应用了静压支承新技术,大大减小了滑阀控制力,从而有可能采用动圈式电磁力发生装置直接带动阀芯,使阀的结构简单,经济性好。 This article briefly introduces several ways to eliminate and reduce the axial hydrodynamic and radial forces in a spool valve and gives an example of an electrical flow control valve that reduces the hydrodynamic and radial forces. In particular, the use of a lightweight aluminum hollow spool and the hydrostatic valve on the application of a new technology, greatly reducing the spool control, which may be used in moving coil electromagnetic force device directly driven spool, The valve structure is simple, good economy.
