G3/4 球阀中这个G3/4是什么意思？
Reply #22018-10-25
G3/4,55度非螺纹密封的管螺纹（GB/T 7307-2001）,3/4的右旋圆柱内螺纹，左旋加标LH，外螺纹表示为G 3/4 A（或B）,A、B表示外螺纹的公差等级。

对的 G是一种螺纹标准 55度锥螺纹 ；NPT螺纹是 60度一般

请问这个3/4是什么意思？
Reply #52018-10-26
公称管径是3/4英吋，通常说的“6吩”管，即管口是6吩管螺纹。G3/4"—6吩管螺纹每英吋14牙，管口螺纹外径d应为26.442mm。
Reply #62018-10-29
G是指G螺纹，3/4是口径，也叫寸，又叫“6吩”，如果常规点就是叫DN20口径
Reply #72019-02-26
G代表螺纹，3/4表示英寸＝DN20
Reply #82019-02-27
G3/4，意思是G螺纹连接，口径3/4寸=DN20
