力士乐DBDA 6 K1X/315溢流阀特点

REXROTH溢流阀DB和DBW型阀门是插入结构的先导型溢流阀，用来限制系统压力(DB)，或者限制(DBW只有螺纹连接)系统的压力。此阀组主要包括阀体和溢流阀的插入元件。管路内的压力作用在阀芯上，通过节流孔作用于球阀芯。管路内的压力超过了弹簧所设定的压力值，球阀芯克服了弹力开启。这时从油口流出的油液通过节流孔流入弹簧腔，由外部控制通道引导到油箱内。当阀芯内高压流体处于平衡状态时，油液通过A口流入B口，同时保持设定的工作压力恒定。DBW型溢流阀(只有螺纹联接)的功能与DB型一样。利用顶向阀可以控制主阀的卸荷。

1.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...

2.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。

3.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。
