A building same-floor drainage device

Abstract

The invention discloses a drainage device on the same floor of a building, which comprises a concentrator and a reinforced swirl three-way pipe; The main pipe and the swirl pipe, the main pipe intersects with the swirl pipe, the main pipe is connected to the upper end of the drainage riser, the upper swirl blade is installed on the inner wall of the main pipe, the lower swirl blade is installed on the inner wall of the drainage riser, the swirl pipe and The swirl directions of the upper swirl blades and the lower swirl blades are the same. The invention can not only realize the drainage of buildings on the same floor, but also enable the water flow of the drainage vertical pipe and the water flow of the horizontal drainage pipe to quickly form a wall-attached swirl flow, so that the airflow in the vertical drainage pipe and the horizontal drainage pipe can be merged smoothly, effectively reducing the drainage. The pressure fluctuation of the standpipe slows down the water flow velocity of the drainage standpipe, greatly increases the drainage capacity of the drainage standpipe, and reduces the noise of the water flow of the standpipe.

Description

technical field [0001] The invention relates to the field of building same-floor drainage, in particular to a building same-floor drainage device. Background technique [0002] The same-floor drainage of the building means that the drainage horizontal pipes on the same floor do not pass through the floor, and are connected to the drainage vertical pipes on the same floor. If there is a situation that needs to be cleaned and dredged, a drainage method that can solve the problem in this layer of casing. Compared with the traditional drainage method of separate floors, the most fundamental concept change of the same-floor drainage scheme is to completely get rid of the shackles between adjacent floors through the rational layout of the pipelines in this floor, and avoid the encroachment of the lower floor space by the horizontal drainage pipes. And caused a series of troubles and hidden dangers. However, the airflow in the drainage standpipe and the drainage horizontal pipe o...

AI Technical Summary

Problems solved by technology

However, the airflow in the drainage standpipe and the drainage horizontal pipe of the existing building same-floor drainage device is not smooth, which greatly disturbs the airflow in the drainage standpipe and generates large pressure fluctuations, which increases the noise of the drainage riser water flow and causes drainage problems. The drainage capacity of the standpipe is reduced, and it is easy to be blocked at the confluence of the drainage standpipe and the drainage horizontal pipe, which requires frequent cleaning
