Drain pipe
The embodiment of the invention provides a drainage pipe. The drainage pipe comprises a pipe body and flow guide ribs. The flow guide ribs are arranged on the inner wall of the pipe body and are spirally arranged in the axial direction, the flow guide ribs comprise a first spiral twisting rib and a second spiral twisting rib, the first spiral twisting rib comprises a first wall surface and a second wall surface, a section circle is determined on any cross section of the pipe body and on the inner wall of the pipe body, the first wall surface and the section circle intersect at a first intersection point, and the second wall surface and the section circle intersect at a second intersection point; the first wall surface intersects with the section circle at a first intersection point, the second wall surface intersects with the section circle at a second intersection point, the perpendicular bisector of the connecting line of the first intersection point and the second intersection point intersects with the section circle at a first midpoint, and the included angle between the outer tangent plane of the first section circle determined by the first midpoint and the first wall surface is 100-120 degrees; the included angle between the outer tangent plane of the first section circle and the second wall face is larger than that between the outer tangent plane of the first section circle and the first wall face, the second twisting ribs are arranged close to the first wall face and away from the second wall face, the radial size of the second twisting ribs is smaller than that of the first twisting ribs, and the number of the second twisting ribs is at least one.
本申请实施例提供了一种排水管，包括：管材本体和导流筋。导流筋设置在管材本体的内壁且沿轴向呈螺旋设置，导流筋包括第一旋扭筋和第二旋扭筋，第一旋扭筋包括第一壁面和第二壁面，在管材本体的任一横截面上，管材本体的内壁确定出截面圆，第一壁面与截面圆相交于第一交点，第二壁面与截面圆相交于第二交点，第一交点和第二交点的连线的垂直平分线与截面圆相交于第一中点，第一中点所确定的第一截面圆外切面与第一壁面之间的夹角为100°‑120°，第一截面圆外切面与第二壁面之间的夹角大于第一截面圆外切面与第一壁面之间的夹角，第二旋扭筋靠近第一壁面而远离第二壁面设置，第二旋扭筋的径向尺寸小于第一旋扭筋的径向尺寸，第二旋扭筋设置有至少一个。
