摘要
采用液压集成设计,拐点开度既可机械液压控制,也可电气液压控制,实现了流量的机械分段关闭和电气分段关闭,两者互为冗余、互不干扰,有效地提高了流量分段关闭装置的可靠性和精确性,可应用于各种需要流量分段关闭的控制系统。
The design of a new integrated hydraulic-control flow stepped closing device is introduced. The inflection opening could be controlled either mechanically or electrically. The mechanical and electrical stepped closing controls are mutually redundant and non-interfering,which effectively improve the reliability and accuracy of the device. It could be used in control systems in which the stepped closing is needed.
