长期以来液压回路的设计思想是用不同的、只具有专用单一功能的液压元件组合成一个能完成一定任务的液压回路。在这种设计思想的指导下,现有液压回路控制元件的特征是只具有固定的单一功能,如各种控制阀;溢流阀、顺序阀、减压阀、调速阀、节流阀、单向阀、换向阀、电液伺服阀、电液比例阀……等。这样,产品的品种繁多,不便于大规模生产,因此价格较贵,这是一;其二,用户只能按现有各种阀类元件所规定的功能,来使用液
For a long time the design idea of the hydraulic circuit is to use different hydraulic components with only a single function to form a hydraulic circuit capable of fulfilling certain tasks. Under the guidance of this design idea, the existing hydraulic circuit control elements are characterized by only having a fixed single function, such as various control valves, relief valves, sequence valves, pressure reducing valves, speed regulating valves, throttle valves, Check valve, valve, electro-hydraulic servo valve, electro-hydraulic proportional valve ...... and so on. In this way, the product variety, not easy for mass production, so the price is more expensive, this is one; Second, the user can only according to the existing functions of various valve components, to use the liquid
