叠加阀是七十年代出现的液压集成化元件。我国从1974年开始叠加阀的系列研制工作,共制订了五个通径(φ6、10、16、20、32)系列,共四十几个品种,公称流量10～200升/分,压力200巴,连接尺寸已列为国家标准且与ISO国际标准四通路换向阀的安装尺寸一致。本文概括地介绍我国叠加阀的发展、系列型谱、应用及特点。图14幅。表7个。 Stacked valve is the seventies appear hydraulic integrated components. A series of research work has been carried out in our country since 1974, with a total of four series (φ6, 10, 16, 20, 32) of 40 varieties with a nominal flow rate of 10-200 liters / min and a pressure of 200 Pakistan, the connection size has been listed as national standards and the ISO international standard four-way reversing valve installation dimensions. This article summarizes the development of laminated valves in our country, series spectrum, applications and features. Figure 14 Figure. Table 7.
