力士乐比例溢流阀DBEM10-51/315XYG24K4M

溢流阀

类型:直动式、先导式

作用:

(1)在不断溢流过程中保持系统压力恒定，起稳压和溢流作用(p,FP

系统’阀口常开) ;

(2)防止液压系统过载，起安全保护作用(p,=1.1~1.2p,max，阀口常闭)

(一)溢流阀的基本结构及其工作原理

1、直动式溢流阀

工作原理:

直接利用液压力与弹簧力相平衡以控制阀芯的启闭动作，从而保证进油口压力基本恒定。

特点:

①阀芯所受的液压力全靠弹簧力平衡，故当系统压力很高时，弹簧必须很硬，导致结构笨重，调压不轻便。一般用于压力小于2.5MPa的低压系统中，作安全阀或背压阀使用。

②由于惯性或负载的变化，导致q、变化，即开口度h的变化，由于k很大，所以p不稳定，稳压精度差;

③结构简单、便宜，但工作时易产生振动和噪音。

电液比例阀是阀内比例电磁铁输入电压信号产生相应动作，使工作阀阀芯产生位移，阀口尺寸发生改变并以此完成与输入电压成比例压力、流量输出元件。阀芯位移也可以以机械、液压或电形式进行反馈。电液比例阀具有形式种类多样、容易组成使用电气及计算机控制各种电液系统、控制精度高、安装使用灵活以及抗污染能力强等多方面优点，应用领域日益拓宽。近年研发生产插装式比例阀和比例多路阀充分考虑到工程机械使用特点，具有先导控制、负载传感和压力补偿等功能。

DBEM 型阀门是一种带有集成电子元件 (OBE) 的先导式溢流阀。此类阀用于限制液压系统的工作压力。根据电气控制值的不同，可使用这些阀门对要限制的系统压力进行无级设置。这些阀门的基本构成包括带有主阀心的壳体、具有大压力限制的叠加阀以及比例先导控制阀。在比例电磁铁上，还配备带控制电子元件的壳体。将电源电压和控制值电压施加于连接器。在出厂时已按照非常低的制造公差对控制值压力特性曲线进行了调节。

施加在通道P中的压力作用于主阀芯。同时，油口P处压力通过带喷嘴的控制油路施加于主阀芯的弹簧负载侧。同时通过连接孔将压力施加到比例先导控制阀的阀架。先导座处液压力可克服比例电磁铁的控制值相关力。如果液压力超过线圈磁力，先导座将会打开。此时先导油即可通过控制油路流向油口 Y 以及油箱；因此控制油路上的主阀芯处将会产生压降。释放从油口P到T的连接。主阀芯可控制油口P处的设定工作压力。

单向阀是气流只能一个方向流动而不能反向流动的方向控制阀。其工作原理与液压单向阀一样。压缩空气从P口进入，克服弹簧力和摩擦力使单向阀阀口开启，压缩空气从P流至A；当P口无压缩空气时，在弹簧力和A口(腔)余气力作用下；阀口处于关闭状 态，使从A至P气流不通。单向阀应用于不允许气流反向流动的场合，如空压机向气罐充气 时，在空压机与气罐之间设置一单向阀，当空压机停止工作时，可防止气罐中的压缩空气回流 到空压机。单向阀还常与节流阀、顺序阀等组合成单向节流阀、单向顺序阀使用。
