Symmetric Y-shaped steel branch pipe

Abstract

The invention discloses a symmetric Y-shaped steel branch pipe which comprises a main pipe, a left branch pipe, a right branch pipe and a crescent rib, wherein the main pipe comprises a main pipe straight pipe section, a main pipe transition pipe section and a main conical pipe section in sequential connection; the left branch pipe comprises a left branch conical pipe section, a left branch pipe transition pipe and a left branch pipe straight pipe section in sequential connection; the right branch pipe comprises a right branch conical pipe section, a right branch pipe transition section and a right branch pipe straight pipe section in sequential connection; the main conical pipe is connected with the left and right branch conical pipes respectively and tangent with a maximum common tangent ball; the left and right branch pipes are symmetric along the axle wire of the main pipe; the crescent rib is arranged at the position where the left and right branch conical pipe sections are connected; and all the pipe sections are in a same plane along the hemline of the longitudinal section of the axle wire. The symmetric Y-shaped steel branch pipe has the advantages of solving the problem that the bottoms of the original pipe sections are uneven and providing convenience for the free drainage and the traffic in the construction period and the overhaul period.

Description

technical field [0001] The invention relates to a steel branch pipe, in particular to a symmetrical Y-shaped steel branch pipe. Background technique [0002] The branch pipe is a special special-shaped pipe section that connects the branch pipe with the main pipe. At present, the steel bifurcation pipes on the diversion pipes of hydropower stations generally arrange the centerlines of the pipe axes of the main pipe and the branch pipes in the same plane. Due to the different diameters of the main pipe and the branch pipes, there is a height difference at the bottom of each pipe section, which leads to the inability to Artesian drainage, inconvenient transportation. Contents of the invention [0003] The purpose of the present invention is to provide a symmetrical Y-shaped steel branch pipe, which can realize self-flow and smooth drainage during the construction period and maintenance period. [0004] To achieve the above object, the present invention takes the following ...
