标准摘要
[中文适用范围]： 本文件给出了法兰头、分体式法兰夹（FCS 和 FCSM）、一体式法兰夹（FC 和 FCM）、适用于四螺杆、分体式和一体式法兰夹类型管连接器的端口和安装表面的一般和尺寸规范。 用于压力为 42 MPa (420 bar1)) 的软管接头。 它还指定了要使用的密封件的尺寸以及容纳密封件的凹槽。 本文件还认识到需要容纳公制螺钉紧固件（类型 1）（适用于 DN 13 至 DN 76），并提供使用现有英制螺钉紧固件（类型 2）（适用于 DN 13 至 DN 51）的方法。 这些连接旨在用于工业和商业产品的液压系统，希望避免使用螺纹连接器。 [外文原描述]： ISO 6162-2:2018 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to four-screw, split and one-piece flange clamp type tube connectors and hose fittings for use at a pressure of 42 MPa (420 bar[1]). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals. ISO 6162-2:2018 also recognizes the need to accommodate metric screw fasteners (type 1) (for DN 13 to DN 76), as well as to provide a means to use existing inch screw fasteners (type 2) (for DN 13 to DN 51). These connections are intended for application in hydraulic systems on industrial and commercial products where it is desired to avoid the use of threaded connectors. [1] 1 bar = 0,1 MPa = 10 5 Pa; 1 Pa = 1 N/m 2 .
