ISO 1179-4:2007标准是连接件的国际标准,它规定了ISO 228-1螺纹和金属对金属密封的螺柱端的尺寸、形状和技术要求。该标准适用于一般用途的液压和气动系统中的螺柱端,但不适用于需要弹性密封的应用。

ISO 1179-4:2007标准中规定了两种类型的螺柱端,分别为类型A和类型B。其中,类型A的螺柱端采用弹性密封,适用于需要密封性能较高的应用;而类型B的螺柱端采用金属对金属密封,适用于一般用途的应用。

ISO 1179-4:2007标准中规定的螺柱端的尺寸和形状必须符合标准中的要求,以确保连接件的互换性和可靠性。此外,标准还规定了螺柱端的表面质量、材料和加工要求等技术要求,以确保连接件的质量和性能。

需要注意的是,ISO 1179-4:2007标准中规定的螺柱端仅适用于一般用途的液压和气动系统中,不适用于需要弹性密封的应用。如果需要弹性密封,应该选择符合ISO 1179-3标准的连接件。

总之,ISO 1179-4:2007标准规定了ISO 228-1螺纹和金属对金属密封的螺柱端的尺寸、形状和技术要求,适用于一般用途的液压和气动系统中的螺柱端,但不适用于需要弹性密封的应用。
