美国Parker派克液压-马达 泵 阀-上海专业Parker派克产品销售商 Description: 美国Parker派克液压 Parker马达 Parker泵 Parker换向阀 Parker比例阀 Parker伺服阀 Parker压力阀 Parker流量阀 Parker单向阀 Parker插装阀 Parker电子产品 Parker油缸 Parker蓄能器 Parker过滤器 Parker工程机械先导控制的控制油流量大约为1 l/min。工作的至低压力为3 bar。控制压力必须大于A口处系统压力的25％。流量的调节精度为0.5％。由于流量特性曲线是渐进的，因此当小流量时，该调节精度在渐进
区域内被改善为0.25％。整个行程的调节时间大约为25ms。当油液由B向A流动时，在关闭的初始位置上由B向A不能有泄漏。在该初始位置上先导控制不需要控制油。回油口T的压力不能高于100 bar。 Parker派克CRK和CRB系列直动式单向阀 Parker派克CRK和CRB系
列直动式单向阀单向阀可以分为两类：CRK和CRB反向截止单向阀以及CRH先导式反向截止单向阀。这两种系列都可以方便地旋入阀体孔中。在接触位置上进口至出口的密封是通过在阀体油口处的端面的密封唇边和加工中心孔所形成的凸缘（像普通的118度钻头顶角
所形成的台肩一样）来实现的。用于密封的研磨孔和滑动斜面是不需要的。旋入的阀的密封是通过一个带螺纹密封的密封锁母和O形圈来实现的。 Parker螺纹插装阀 Parker螺纹插装阀...
