Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0025] ginseng figure 1 As shown, a swirl type double-standpipe drainage system in a specific embodiment of the present invention includes a first standpipe 10 and a second standpipe 20 arranged in parallel, the first standpipe 10 is used for drainage, and the second standpipe The pipe 20 is used for exhausting. The first standpipe 10 and the second standpipe 20 communicate with each other through a communication pipe 30 . The gas in the first riser 10 flows through the communication pipe 30 to the second standpipe 20 for discharge.

[0026] Specifically, combined with figure 2 As shown, the first s...

Abstract

The invention discloses a swirling flow type double-vertical-pipe drainage system. The drainage system comprises a first vertical pipe and a second vertical pipe which are arranged in parallel, wherein the first vertical pipe is used for draining water, the second vertical pipe is used for exhausting air, the first vertical pipe and the second vertical pipe communicate with each other through a communicating pipe, the air in the first vertical pipe flows into the second vertical pipe through the communicating pipe to be exhausted, the first vertical pipe is an enhanced type inner-spiral water drain pipe, a plurality of spiral ribs are arranged in the first vertical pipe, and the communicating pipe is arranged slantwise upwards from the first vertical pipe to the horizontal direction of the second vertical pipe, so that the water in the first vertical pipe is prevented from overflowing to the second vertical pipe. With the adoption of the swirling flow type double-vertical-pipe drainage system, the nappe phenomenon can be effectively eliminated, the water velocity of the vertical pipes can be retarded, the hydraulic condition of the vertical pipes can be improved, the water flow pressure fluctuation and water flow noise of the vertical pipes can be reduced, and thus the water discharge capacity is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of building water supply and drainage, and in particular relates to a swirl type double riser drainage system. Background technique [0002] The indoor drainage pipe system of the building is composed of drainage vertical pipes and horizontal drainage pipes. The drainage outlets of sanitary appliances are provided with traps connected to the horizontal drainage pipes through branch pipes, and then discharged into the vertical pipes from the horizontal pipes, and finally discharged to the outdoor inspection well. When a relatively large flow of waste water entrains solid waste through the horizontal pipe or vertical pipe, it acts like a piston. The front end forms an air block, which affects the drainage flow, and the rear end easily forms negative pressure to empty the water in the trap. Cause the peculiar smell in the pipeline to escape to the room. [0003] There are two types of indoor drainage systems i...
