标准摘要
[中文适用范围]： 本文件规定了适用于外径 4 毫米至 42 毫米（含）的黑色金属和有色金属管的使用切割环和 O 形密封锥体（称为 DKO）的 24° 锥形连接器的一般和尺寸要求。 这些连接器适用于本文件规定的压力和温度范围内的流体动力和一般应用。 它们用于将平端管和软管接头连接到符合表 1 所示工作压力的液压系统中的全流量连接。 因为许多因素会影响系统令人满意地运行的压力。 ，这些值不应被理解为保证的最小值。 对于每种应用，用户和制造商都应进行充分的测试和审查，以确保满足所需的性能水平。 注 1：对于液压流体动力应用中的新设计，参见 9.6 中给出的要求。 如果应用要求允许使用弹性密封件，则首选符合国际标准并采用弹性密封件的连接器设计。 注 2：对于在规定的压力和/或温度限制之外的条件下使用，见 5.4。 本文件还规定了这些连接器的性能和资格测试。 [外文原描述]： This document specifies the general and dimensional requirements for 24° cone connectors using cutting ring and O‑ring seal cone (referred to as DKO) suitable for use with ferrous and non‑ferrous tubes with outside diameters from 4 mm to 42 mm inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in this document. They are intended for the connection of plain end tubes and hose fittings to ports in accordance with ISO 6149‑1, ISO 1179‑1 and ISO 9974‑1. (See ISO 12151‑2 for a related hose fitting specification.) These connectors provide full-flow connections in hydraulic systems operating to the working pressures shown in Table 1. Because many factors influence the pressure at which a system performs satisfactorily, these values are not intended to be understood as guaranteed minimums. For every application, sufficient testing is meant to be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met. NOTE 1 For new designs in hydraulic fluid power applications, see the requirements given in 9.6. Where the requirements of the application allow for the use of elastomeric seals, connector designs that conform to International Standards and incorporate elastomeric sealing are preferred. NOTE 2 For use under conditions outside the pressure and/or temperature limits specified, see 5.4. This document also specifies a performance and qualification test for these connectors.
