In this way, the formation of a groove it ABCDEA "∞" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

In this way, also the formation of a groove ABCDEA "∞"-shaped seal space (such as single-head screw, the groove will shun Rao axial screw plate to the mouth through the suction row, unable to form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

In this way, the formation of a groove it ABCDEA "i" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

那样，凹槽ABCDEA也便组败一个&i&形的密封空间(如采取双尾螺纹，则凹槽将逆轴向盘饶螺杆，将吸排口贯通，无奈构成稀封)。
