汽车管路接头

[中文适用范围]： 本SAE标准涵盖了适用于汽车、家电及相关领域通用应用的各种管件接头的完整通用和尺寸规格。有关用于汽车制动系统中的可重复使用（推入式连接）接头的性能要求，请参阅SAE J1131。喇叭口型接头应按照图1至图4以及表3至表5的规定进行制造。倒喇叭口型接头应按照图5至图11以及表3、表6、表7、表8和表9的规定进行制造。与倒喇叭口管接头相关的量具和检测方法详见附录A。适用于退火铜合金管的一般用途的锥形套管压缩型接头应按照图12至图17以及表3、表10、表11和表12的规定制造。为确保良好性能，在同时存在这两种类型接头的连接区域中，组装时不应将球形套管压缩型接头组件（请参见SAE J246）与锥形套管压缩型接头组件混用。与喇叭口和倒喇叭口接头配合使用的管材上单个和双个45度喇叭口的尺寸，详见SAE J533中的图2和表3。以下通用规格补充了表3至表13中所有类型接头的尺寸数据，适用于所有未指定的细节。 [外文原描述]： This SAE Standard covers complete general and dimensional specifications for the various types of tube fittings intended for general application in the automotive, appliance, and allied fields. Refer to SAE J1131 for the performance requirements of reusable (push to connect) fittings intended for use in automotive air brake systems. Flare-type fittings shall be as specified in Figures 1 to 4 and Tables 3 to 5. Inverted flared-type fittings shall be as specified in Figures 5 to 11 and Tables 3, 6, 7, 8, and 9. Gauges and gauging procedures pertaining to inverted flared tube fittings are given in Appendix A. Tapered sleeve compression-type fittings intended for general use with annealed copper alloy tubings shall be as specified in Figures 12 to 17 and Tables 3, 10, 11, and 12. To assure satisfactory performance, spherical sleeve compression-type fitting components (refer to SAE J246) should not be intermixed with tapered sleeve compression-type fitting components when assembling connections in areas where both types are available. Dimensions of single and double 45-degree flares on tubing to be used in conjunction with flared and inverted flared fittings are given in Figure 2 and Table 3 of SAE J533. The following general specifications supplement the dimensional data for all types of fittings contained in Tables 3 to 13 with respect to all unspecified detail.
