柱状节流阀在机床中各润滑点供油量难以保证。供油量过多易泄漏，供油量过少易使机件产生热量、磨损和研伤。为此，我们设计了图示柱状节流阀。它可直接安装在具有一定供油压力的管路中，通过转动外套２使钢球３与阁芯１之间形成缝隙，从而起到调节流量的作用。外套２用透... Columnar throttle valve lubrication points in the machine is difficult to guarantee the amount of oil supply. Too much fuel leakage easily leaks, too little fuel supply easy to produce heat, wear and grinding injury. To this end, we designed a graphical column throttle. It can be directly installed in the pipeline with a certain supply pressure, by rotating the jacket 2 so that the gap between the ball 3 and the core 1, which play a role in regulating the flow. Jacket 2 through ...
