旋转式微量节流阀,是我院研制液压传动单晶炉过程中,为解决低速运动无爬行而提出的课题。由以工人为主体的三结合小组研制成功。此阀应用在我院自行设计制造的 YDL-1型、YDL-2型液压单晶炉上,满足了单晶炉籽晶轴慢速运动平稳升降的要求,经过一年多生产实际的考验,初步证明,这种新结构的微量节流阀性能良好。并于1971年扩大使用范围,应用于“L016型”大型多籽晶轴液
Rotary micro-throttle, is our hospital to develop hydraulic transmission single crystal furnace process, in order to solve the problem of low-speed movement without crawling. By the workers as the main body of the three combined groups successfully developed. This valve is applied to the YDL-1 type and YDL-2 type hydraulic single crystal furnace designed and manufactured by our institute, which meets the requirement of smooth movement of slow moving crystal axis of single crystal furnace. After more than one year of actual production, Preliminary proof, the new structure of the micro-throttle valve performance is good. And in 1971 to expand the scope of use, used in “L016-type” large multi-seed crystal axis
