A plastic pipe drainage system with spiral single blade

Abstract

The invention discloses a spiral single-blade plastic pipeline water discharging system. The spiral single-blade plastic pipeline water discharging system comprises a tee coupling, an upper vertical pipe, a lower vertical pipe and a transverse pipe, wherein the upper vertical pipe, the lower vertical pipe and the transverse pipe are respectively connected to an upper connector, a lower connector and a transverse connector of the tee coupling, spiral single blades are respectively and coaxially arranged on the inner walls of the upper vertical pipe and the lower vertical pipe along the axis direction of the vertical pipe, and an arc transitional structure is arranged on the junction of the root part of each spiral single blade and the inner walls of the upper vertical pipe and the lower vertical pipe. The spiral single-blade plastic pipeline water discharging system has advantages of high water discharging capability, small fluctuation of the water discharging pressure, low water discharging noise, and the like.

Description

technical field [0001] The invention relates to the field of building drainage pipes, in particular to a plastic pipe drainage system with a spiral single-blade with special drainage performance (having the advantages of large drainage energy, small drainage pressure fluctuation, and low drainage noise). Background technique [0002] Plastic pipe is a commonly used pipe for building drainage, but because the inner wall of the plastic pipe is smooth and the frictional resistance is small, when it is used in a building drainage riser, the water flow velocity is high, and when the flow rate is slightly larger, it is easy to form a water plug flow (water plug flow). : When the building drainage riser is used for gravity drainage, when the flow rate is too large, the thickness of the water film attached to the pipe wall is too large, or is affected by the structure, the water flow forms a central water mass and falls in the pipeline, forming a mass plug-like falling in the pipelin...

Problems solved by technology

[0006] The purpose of the present invention is to solve the deficiencies and defects of the existing riser system, which are prone to pressure fluctuations, water seal damage, floor drain back odor, noise increase, etc., when the displacement increases, by changing the helix The shape of the rib structure provides a spiral with the purpose of changing the shape of the falling water flow in the drainage standpipe, reducing the pressure fluctuation in the pipe during drainage, reducing the speed of the falling water flow, avoiding water seal damage and toilet odor, reducing drainage noise, and improving drainage capacity.
