淄博鼎科贸易有限公司销售派克进口RAH系列先导式溢流阀

先导式溢流阀设计用于连续工作的应用系统。由于稳定性好和压力抬升小, 先导式溢流阀是调定液压系统压力的选择, 压力抬升小且工作噪声低。

该系列先导式螺纹插装溢流阀的供货规格为与 -08 至 -20 规格的插件安装孔相配, 适合用于这样一种连续工作的系统, 这种系统要求溢流阀工作在其它任何间歇使用的阀件之前。它们可用来长时间地保持系统的压力, 此外, 在流量变化可能较大的系统中, 先导式溢流阀能适应这种变化, 而不会造成过度的压力抬升或有时称之为压力超调。由于液流流过的阀的开口面积状态, 此类滑阀型溢流阀工作时比传统的直动式阀更为静音。有一点必须要考虑的是滑阀型元件的泄漏, 由于结构的问题, 滑阀型阀会有少量的泄漏, 然而, 直动式阀的泄漏则可不予考虑, 除非压力达到它的开启压力值。滑阀型溢流阀不可用于负载持住应用工况。

一般的回路应用包括: 工作油叉溢流, 回转溢流, 油口安全阀, 溢流先导阀, 系统溢流阀, 压力限制, 峰值溢流, 马达刹车, 换向溢流, 负载传感溢流。
