[0002] The butterfly head is mainly composed of a spherical surface, a cylindrical straight edge with a certain height and a transition part with a curvature radius smaller than the spherical surface radius connecting the above two parts. The disc head is a continuous curved surface. At the connection of the three parts, the meridian curvature radius has a sudden change. Due to the change in curvature, there is a bending stress.
