55°圆锥管螺纹型式和尺寸表
55°圆锥管螺纹型式和尺寸ZG是锥管的汉语拼音第一个字母。
就是锥管螺纹的意思。
3/4是四分之三英寸。
是指管子的内径是3/4英寸。
准确的来讲它的内径是19.05毫米，但这是老标准，现在已经不用了。
现在的国标规定ZG3/4〃螺纹内径是20毫米。
它的表示方法应该是：ZG3/4〃。
其中（〃）是英寸的代表符号。
一英寸等于25.4毫米。
一英寸等于8英分。
3/4的来历是6/8=3/4。
俗称6分。
同样ZG1/2〃螺纹的管子内径≈15毫米。
俗称4分。
ZG1〃螺纹的管子内径≈25毫米。
俗称1寸。
ZG11/2〃螺纹的管子内径≈32毫米。
俗称1寸半。
.....。
锥管螺纹只用于液压系统连接；而管螺纹G3/4〃只用于水管连接。
锥管螺纹与管螺纹极为相似，区别只在锥度上。
国标螺纹的一般知识一. 螺纹的分类1. 螺纹分内螺纹和外螺纹两种；2. 按牙形分可分为：１）三角形螺纹２）梯形螺纹３）矩形螺纹４）锯齿形螺纹；3. 按线数分单头螺纹和多头螺纹；4. 按旋入方向分左旋螺纹和右旋螺纹两种, 右旋不标注，左旋加LH，如M24×1.5LH；5. 按用途不同分有：米制普通螺纹、用螺纹密封的管螺纹、非螺纹密封的管螺纹、60°圆锥管螺纹、米制锥螺纹等二. 米制普通螺纹1. 米制普通螺纹用大写M表示，牙型角2α=60°（α表示牙型半角）；2. 米制普通螺纹按螺距分粗牙普通螺纹和细牙普通螺纹两种；2.1. 粗牙普通螺纹标记一般不标明螺距，如M20表示粗牙螺纹；细牙螺纹标记必须标明螺距，如M30×1.5表示细牙螺纹、其中螺距为1.5。
2.2. 普通螺纹用于机械零件之间的连接和紧固，一般螺纹连接多用粗牙螺纹，细牙螺纹比同一公称直径的粗牙螺纹强度略高，自锁性能较好。
3. 米制普通螺纹的标记：M20-6H、M20×1.5LH-6g-40,其中M 表示米制普通螺纹，20表示螺纹的公称直径为20mm，1.5表示螺距，LH表示左旋，6H、6g表示螺纹精度等级，大写精度等级代号表示内螺纹，小写精度等级代号表示外螺纹，40表示旋合长度；3.1. 常用米制普通粗牙螺纹的螺距如下表(螺纹底孔直径：碳钢φ＝公称直径－P；铸铁φ＝公称直径－1.05~1.1P；加工外螺纹光杆直径取φ＝公称直径－0.13P)：表1 常用米制普通粗牙螺纹的直径/螺距公称直径螺距P 铸铁底孔碳钢底孔外螺纹光杆直径公称直径螺距P 铸铁底孔碳钢底孔外螺纹光杆直径M5 0.8 4.1 4.2 4.9 M24 3 20.8 21 23.7M6 1 4.9 5 5.9 M27 3 23.8 24 26.7M8 1.25 6.6 6.7 7.9 M30 3.5 26.3 26.5 29.6M10 1.5 8.3 8.5 9.8 M33 3.5 29.3 29.5 32.6M12 1.75 10.3 10.4 11.8 M36 4 31.7 32 35.5M14 2 11.7 12 13.7 M42 4.5 37.2 37.5 41.5M16 2 13.8 14 15.7 M48 5 42.5 43 47.5M18 2.5 15.3 15.5 17.7 M56 5.5 50 50.5 55.5M20 2.5 17.3 17.5 19.7 M64 6 57.5 58 63.53.2. 米制普通内螺纹的加工底孔直径可用下式作近似计算：d=D-1.0825P,其中Ｄ为公称直径，Ｐ为螺距。

注： 1。 本螺纹基面上各直径等于圆柱管螺纹的各相应直径.当同一公称尺寸的管与接头旋合而无过盈时，螺纹的接合长度等于L2
2.不论实际上L2值如何，L1和L2实际之差不得小于本表中所列的L1和L2之差，以保证基面与螺尾之间有一定数量的完整牙形。
3。 dr的尺寸供参考。
4. 用圆柱形管螺纹的接头来连接圆锥形管螺纹的管子时，前者应做成圆顶牙形，并按2级精度制造。
