力士乐DBE（M）型比例溢流阀

力士乐DBE（M）型比例溢流阀哪里好，请找上海颖哲力士乐经销商。的系统压力可随电气输入信号连续改变。它主要包括带比例电磁铁的先导阀和带主阀芯总成的主阀。是座阀结构的先导式溢流阀通径（NG）10,25,32，压力至31.5MPa 流量至600L/min。Rexroth比例溢流阀可以按比例调定溢流的流量，对系统的控制更加精密。

   力士乐DBE（M）型比例溢流阀又比例先导阀，安全阀和插装式主阀组成。比例先导阀控制主阀遥控口。力士乐DBE型比例溢流阀按输入电流大小成比例地控制液压系统的压力，阀的通油能力大，适用于流量较大的液压系统

    力士乐DBE型比例溢流阀的系统压力极限由比例电磁铁2设定，与电流有关，来自系统的压力作用于主阀芯4，与此同时，经过装有节流孔5的先导管作用于主阀芯4的弹簧加载侧并作用在先导阀芯6.如果系统压力升高得超过对应着电磁铁力的设定值，则先导阀芯6打开。
    现在先导油可以流回油箱，节流孔组产生作用在主阀芯4上的压降，使它从阀座上升起并打开从泵到油箱的通路。
    力士乐DBEM行比例溢流阀为了保护系统免遭比例电磁铁2处不能允许的高电流尖峰引起的不能允许的高压之害，有一种供选方案是装设一个弹簧加载的压力溢流阀7提供zui高保护。

    力士乐DBE(M)型比例溢流阀由直流比例电磁铁和先导型溢流阀组成。工作原理是：当输入一个电信号时，比例电磁铁1便产生一个相应的电磁力，它通过推杆2和弹簧3的作用，使锥阀4接触在阀座5上，因此打开的液压力与电流成正比，形成一个比例先导压力阀。孔a为主阀阀芯6的阻尼孔，由先导式溢流阀工作原理，对溢流阀阀芯6上的受力分析可知，电液比例溢流阀进口压力的高低与输人信号电流的大小成正比，即进口油压受输入电磁铁的电流大小控制。若输入信号电流是连续地按比例地或按一定程序变化，则比例溢流阀所调节的液压系统压力，也连续地按比例地或按一定程序地进行变化。从而将手调溢流阀，改为电信号控制。

　　力士乐DBE(M)型比例溢流阀实现多级压力控制，当以不同电流J1、j2、J3、J4和J5输入时，溢流阀就可得到五种压力控制，它与普通溢流阀的多级压力控制相比，液压元件数量少，系统简单。若输入的是连续变化的信号则可实现连续的压力控制。

　　先导型比例溢流阀。它的先导部分是直动式比例压力阀，可直接作为直动式比例溢流阀使用。若与普通压力阀组合，可组成先导型比例溢流阀、比例减压阀和比例顺序阀等元件。

    力士乐比例溢流阀是一种能够使所输出油液的参数（压力）随输入电信号参数（电流或电压）的变化而成比例地变化的液压控制阀。通过电磁铁电压的变化产生不同大小的推力作用在阀芯上，从而得到连续变化的液压压力。
