标准摘要
[中文适用范围]: ISO 8434 的这一部分规定了钢制 O 形圈面密封连接器的设计和性能的一般和尺寸要求,适用于外径 6 毫米至 38 毫米(含)的管子或软管内径。 这些连接器适用于流体动力和一般应用,其中弹性密封件可用于防止流体泄漏,包括由组装过程的变化引起的泄漏。 它们用于根据 ISO 6149-1 将管子和软管接头连接到端口。 (有关相关软管接头规范,请参阅 ISO 12151-1。 )这些连接器在从 6,5 kPa [0,065 bar 3)] 绝对压力到表 1 所示工作压力的液压系统中提供防漏、全流量连接由于许多因素会影响系统令人满意地运行的压力,因此这些值不应被理解为保证的最小值。 对于每种应用,建议用户和制造商进行充分的测试和审查,以确保满足所需的性能水平。 注:对于在超出指定压力和/或温度限制的条件下使用,请参见 5.3。 通过更换套管,可以适应公制和英制管材(参见附录 D)。 过去,这些连接器主要用于英制管道。 对于新的和未来的设计,首选使用公制管道。 ISO 8434 的这一部分还规定了 O 形圈面密封连接器的性能和资格测试。 [外文原描述]: ISO 8434-3:2005 specifies the general and dimensional requirements for the design and performance of O-ring face seal connectors made of steel for tube outside diameters or hose inside diameters of 6 mm through 38 mm, inclusive. These connectors are for use in fluid power and general applications where elastomeric seals can be used to prevent fluid leakage, including leakage caused by variations in assembly procedures. They are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149-1. Both metric and inch tubing can be accommodated by changing the sleeve. In the past, these connectors have been used predominantly with inch tubing. For new and future designs, the use of metric tubing is preferred. ISO 8434-3:2005 also specifies a performance and qualification test for O-ring face seal connectors.
