标准摘要
[中文适用范围]： 本部分SAE J514涵盖了37度扩口管接头的一般和尺寸规格。附录B还包括带有NPTF管螺纹的37度扩口接头。这些接头适用于工业设备和商业产品上的液压系统的一般应用。这些接头能够在表6规定的工作压力下提供防漏、全流量的液压系统连接。由于许多因素会影响液压系统的性能，表6中的数值不应被视为保证的最低值。对于任何应用，建议用户和接头制造商进行充分的测试和审查，以确保性能水平安全可靠。 [外文原描述]： This SAE Standard covers complete general and dimensional specifications for 37 degree flared and flareless types of hydraulic tube fittings and O-ring plugs. Also included are pipe fittings and adapter unions for use in conjunction with these tube fittings. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products.These fittings are capable of providing leakproof, full flow connections in hydraulic systems operating at working pressures as specified in Table 1 for respective sections.Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, the values shown in SAE J1065 should not be construed as a guaranteed minimum.For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting manufacturer to assure that performance levels will be safe and satisfactory.The standard is divided into six sections as follows:Section 1 —37 Degree Flare Tube FittingsSection 2 —Flareless Tube FittingsSection 3 —O-ring Plugs (for O-ring Ports see SAE J1926)Section 4 —Hydraulic Pipe Fittings (formerly SAE J926)Section 5 —Adapter Unions (formerly in SAE J516)Section 6 —Tables for Calculating Dimensions on Special SizesCross Reference: ANSI/B1.20.1,ANSI/B1.20.3,ASTMB117,J1065_201605,J343_201605,J405_201801,J476,J533_201702
