ISO/TC131/SC3/WG4所提出的DP6403文件是名为《液压传动一试验方法一流量和压力控制阀》的标准草案。在国家标准总局和液压与气动技术标准委员会领导下,以704研究所为首的、有二所四校一厂参加的工作组对这个草案进行了研究和验证。笔者参加了这项工作,对草案中有关流量调节阀试验方法的条文,提出以下看法。同时,对草案重点内容和特点作扼要的介绍和分析。为了以下叙述方便,将ISODP6403标准草案有关流量调节阀试验方法这一局部内容,简称为ISO标准草案。
The DP6403 document proposed by ISO / TC131 / SC3 / WG4 is a draft standard entitled “Hydraulic Transmission - Test Methods - Flow and Pressure Control Valves”. Under the leadership of the State Bureau of Standards and the Hydraulic and Pneumatic Technical Standards Committee, a working group led by the Institute 704 led by two four-school and one-factory participated in the study and verification of the draft. I participated in this work, the draft bill about the flow control valve test method, put forward the following views. At the same time, the key content and characteristics of the draft are briefly introduced and analyzed. For the convenience of the following description, the ISODP6403 standard draft on the flow control valve test method of this part, referred to as the ISO draft standard.
