Description

Pressure-stabilizing mute double-riser drainage system

Technical Field

The invention relates to the field of double-riser drainage systems, in particular to a pressure-stabilizing mute double-riser drainage system.

Background

At present, building drainage systems on the market are generally divided into a single-stand-pipe drainage system and a double-stand-pipe drainage system, the single-stand-pipe drainage system and the double-stand-pipe drainage system are respectively suitable for a bottom building and a high-rise building, the high-rise buildings are more and more along with the development of the society and the improvement of science and technology, the double-stand-pipe drainage system is also more and more widely used, and the drainage stand pipes are generally plastic pipes.

The plastic pipe is a common pipe for building drainage, but because the inner wall of the plastic pipe is smooth and the friction resistance is small, when the plastic pipe is used for a building drainage vertical pipe, the water flow speed is high, and when the flow is slightly large, water plug flow is easily formed, so that large pressure fluctuation and bad smell return in a toilet are caused in the pipe. Therefore, the plastic drainage pipe with the internal spiral pipe is gradually used in the market, but the plastic drainage pipe with the internal spiral pipe is structurally characterized in that a plurality of triangular spiral ribs with certain screw pitches and certain heights are arranged on the inner wall of the pipe, so that the water flow falling along the pipe wall forms spiral wall-attached water flow, the falling speed of the water flow is reduced, and the friction resistance of the pipe wall is increased, so that the pressure fluctuation of the vertical pipe during drainage is reduced, the water seal of a floor drain is prevented from being damaged, and the odor return phenomenon of a toilet is reduced.

Under the condition of small drainage flow, the traditional internal thread plastic drainage pipe can obviously reduce the pressure fluctuation in the pipe and the falling speed of water flow, and the drainage capability is improved compared with that of a smooth wall plastic pipe; however, when the water discharge is increased, the tendency of water flow to leave the pipe wall is increased, the water flow impacts the pipe wall alternately, the pressure fluctuation in the pipe is obviously increased, the vibration of the pipe is severe, the noise is very large, and the phenomena of water seal damage and odor return in a toilet are caused.
