第一节弯管斜势计算的第一种基本方法什么叫做弯管斜势锅炉管子进行弯管时,弯管机的转盘是在水平面上回转的,管子的弯头平面总是和水平面重合。但空间弯曲管子的弯头平面是不在同一平面上的,相连的两个弯头平面间有一个夹角,也就是两弯头平面的两面角,如图3-1所示,∠θ为两面角。对于相连的两个空间弯头,若将第一个弯头平面
The first section of the basic method of calculation of elbow bend What is called the pipe bend elbow boiler pipe bending, pipe bender turn in a horizontal plane, the pipe elbow plane always coincides with the horizontal plane. However, the curved pipe bending space elbow plane is not the same plane, the two connected elbow plane has an angle, that is, two elbow plane angle, as shown in Figure 3-1, ∠ θ for the two sides angle. For the two connected space elbows, the first elbow plane will be used
