标准摘要
[中文适用范围]： 本文件给出了适用于压力为 42 MPa [420 bar1)] 的四螺钉、一体式方形法兰夹式管接头和软管接头的法兰头、法兰夹、端口和安装表面的一般和尺寸规格。 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。 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]： This document gives general and dimensional specifications for flanged heads, flange clamps, ports and mounting surfaces applicable to four-screw, one-piece square 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. 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 .
