标准摘要
[中文适用范围]： 本文件规定了与 ISO 6149-2 和 ISO 6149-3 中所述的可调节和不可调节螺柱端部一起使用的公制端口尺寸。 对于不可调节螺柱端部，符合本文件的端口可在高达 63 MPa (630 bar1)) 的工作压力下使用；对于可调节螺柱端部，可在高达 40 MPa (400 bar) 的工作压力下使用。 允许的工作压力取决于端口尺寸、材料、设计、工作条件、应用等。 请参阅 ISO 6149-2 注：本文件的引言给出了用于液压流体动力应用新设计的端口和螺柱端部的建议。 [外文原描述]： This document specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends as described in ISO 6149‑2 and ISO 6149‑3. Ports in accordance with this document can be used at working pressures up to 63 MPa (630 bar[1]) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO 6149‑2 and ISO 6149‑3 for pressure ratings. NOTE The Introduction of this document gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications. [1] 1 bar = 0,1 MPa = 10 5 Pa; 1 MPa = 1 N/mm 2 .
