The results show that the new type of proportional direction valve is of good steady state control characteristics and equal displacement characteristics. The linearity of the control curve of the main spool displacement is well. However, there exists a certain neutral position control dead zone.
研究结果表明,新型比例方向阀的稳态特性和等位移特性良好,主阀芯位移控制曲线的线性度也较好,但有一定的中位控制死区。
the resulting differential pressure is applied to the ends of the spool valve, raising it from its spring-centered null position.
结果导致滑阀端部产生差压并将其自弹簧中心电气零位提升。?
