在自制的气液联动机构机床中,为了实现慢速工作进给和快速退回的动作要求,往往需要在管路中装置单向节流阀,控制流量的大小,以改变速度的快慢。我厂九车间的师傅们试制成功了一种轴向移动式单向节流阀(见图),经在两台机床上使用,性能较好。单向节流阀的工作是这样的:油液从A向流入,B向流出时,由于压力油的作用,使钢球克服弱弹簧的弹力,压向下方,则油路便打开,油液
In the self-made gas-liquid linkage mechanism machine, in order to achieve the requirements of slow work feed and quick return, often need to install one-way throttle in the pipeline to control the size of the flow, in order to change the speed of the speed. Our factory nine workshop master who succeeded in the trial of a one-way axial movement of the throttle (see photo), after the use of two machines, better performance. One-way throttle work is this: the fluid from A to inflow, B to the outflow, due to the role of pressure oil, so that the steel ball to overcome the weak spring force, pressure down, the oil will open, the oil
