| 摘 要： | 2D伺服螺旋数字阀作为先导控制大流量高频响的换向阀,结构上利用2D阀的阀芯的双自由度运动,阀芯由步进电机驱动旋转,通过高低压孔的开口通断来改变敏感腔的压力,从而推动阀芯轴向运动。大流量高频换向阀的小阀芯与2D阀的阀芯由球头刚性连接,获得所需的大行程,驱动主阀芯运动。基于MATLAB建立2D阀的数学模型,该模型的仿真结果能较为准确地描述2D阀的动静态特征。

| Abstract: | The 2D spiral digital servo valve as a pilot valve controls reversal valve with high flow and high-frequency response.The structure uses two degree's freedom movement of 2D valve spool.The spool is rotated by a stepper motor,which drives high and low pressure opening hole on or off to changes pressure in the sensitive chamber,thus promoting the spool axial movement.Small spool of large flow and high-frequency valve and spool of 2D valve are averigidly connected by the ball.The small spool gets the trip and ... |
