定压溢流作用:在定量泵节流调节系统中,定量泵提供的是恒定流量。当系统压力增大时,会使流量需求减小。此时溢流阀开启,使多余流量溢回油箱,保证溢流阀进口压力,即泵出口压力恒定(阀口常随压力波动开启)。 稳压作用:溢流阀串联在回油路上,溢流阀产生背压运动部件平稳性增加。 系统卸荷作用:在溢流阀的遥控口串接溢小流量的电磁阀,当电磁铁通电时,溢流阀的遥控口通油箱,此时液压泵卸荷。溢流阀此时作为卸荷阀使用。 安全保护作用:系统正常工作时,阀门关闭。只有负载**过规定的极限(系统压力**过调定压力)时开启溢流,进行过载保护,使系统压力不再增加(通常使溢流阀的调定压力比系统较高工作压力高10%~20%)。 实际应用中一般有:作卸荷阀用,作远程调压阀,作高低压多级控制阀,作顺序阀,用于产生背压(串在回油路上)。 溢流阀一般有两种结构:1、直动型溢流阀 。2、先导型溢流阀。 对溢流阀的主要要求:调压范围大,调压偏差小,压力振摆小,动作灵敏,过载能力大,噪声小。 博世力士乐rexroth叠加式溢流阀 先导式溢流阀 ZDB和Z2DB型 6通径 R900598663 ZDB6VA3-4X/50V R900598455 ZDB6VP1-4X/315V R900598152 ZDB6VB1-4X/100V R900597389 ZDB6VP7-4X/315V

二)溢流阀的结构和工作原理 常用的溢流阀按其结构形式和基本动作方式可归结为直动式和先导式两种。 1.直动式溢流阀 直动式溢流阀是依靠系统中的压力油直接作用在阀芯上与弹簧力等相平衡,以控制阀芯的启闭动作,溢流阀是利用被控压力作为信号来改变弹簧的压缩量,从而改变阀口的通流面积和系统的溢流量来达到定压目的的。当系统压力升高时,阀芯上升,阀口通流面积增加,溢流量增大,进而使系统压力下降。溢流阀内部通过阀芯的平衡和运动构成的这种负反馈作用是其定压作用的基本原理,也是所有定压阀的基本工作原理。 2.先导式溢流阀 图-19所示为先导式溢流阀的结构示意图,由于先导阀芯一般为锥阀,受压面积较小,所以用一个刚度不太大的弹簧即可调整较高的开启压力,用螺钉调节导阀弹簧的预紧力,就可调节溢流阀的溢流阀压力。 先导式溢流阀有一个远程控制口K,如果将K口用油管接到另一个远程调压阀(远程调压阀的结构和溢流阀的先导控制部分一样),调节远程调压阀的弹簧力,即可调节溢流阀主阀芯上端的液压力,从而对溢流阀的溢流压力实现远程调压。但是,远程调压阀所能调节的较高压力不得**过溢流阀本身导阀的调整压力。当远程控制口K通过二位二通阀接通油箱时,主阀芯上端的压力接近于零,主阀芯上移到较高位置.阀口开得很大。由于主阀弹簧较软,这时溢流阀p口处压力很低,系统的油在低压下通过溢流阀流回油箱,实现卸荷。
