锥阀与普通电液阀相比,具有许多独特的优点,近年来在液压系统中得到了广泛的应用。但它仍不能满足某些高灵敏度液压系统的要求,特别是大流量系统。例如在压机的空程下降和加压时,进排液阀打开后不能及时关闭,将使压机下滑超程,给人身和设备安全带来威胁。因此,提高锥阀关闭速度势在必行。 Compared with the common electro-hydraulic valve, the cone valve has many unique advantages and has been widely used in the hydraulic system in recent years. But it still can not meet the requirements of some high sensitivity hydraulic system, especially the large flow system. For example, when the air compressor drops and pressurizes, the intake and exhaust valve can not be closed after being opened, which will cause the compressor to slip and overtake, posing a threat to the personal and equipment safety. Therefore, to improve the cone valve closing speed is imperative.
