液压阀联合设计组自1973年成立以来,经过四年多的努力,完成了液压阀新系列的设计和典型样机的试制与试验工作。液压阀新系列的公称压力为320公斤力/厘米~2,最大公称流量为1250升/分。这套阀包括压力控制阀、流量控制阀、方向控制阀三大类,其中有不少品种和规格是新发展的,有的在结构上有所改进。本文介绍液压阀新系列的基本情况、结构特点、三化工作情况、与国外先进水平的差距,文末还谈到提高质量的有关问题。
Hydraulic valve joint design team since its establishment in 1973, after more than four years of hard work, completed a new series of hydraulic valve design and prototype prototype trial and test work. The new series of hydraulic valve nominal pressure of 320 kg / cm ~ 2, the maximum nominal flow of 1250 liters / min. This valve includes pressure control valve, flow control valve, directional control valve three categories, of which many varieties and specifications are new developments, and some structural improvements. This article introduces the basic situation of the new series of hydraulic valves, structural characteristics, the work of the three, the gap with the advanced level abroad, the text also talked about to improve the quality of the relevant issues.
