Problems solved by technology
[0002] At present, there are more and more high-rise buildings. Due to the thin pipes, unreasonable design of bends, and accumulation of debris, especially in the cold season, due to the influence of easy agglomeration of oil pollution, the sewer pipes are easy to accumulate and block at the sharp bends at the bottom, resulting in poor sewage discharge. Therefore, due to the blockage, the sewage will accumulate in the pipe and flow back to the lowest building connected with the main sewer pipe. Especially sometimes when there is no one at home for a long time, a large amount of sewage will enter and the residents will suffer.

Embodiment approach
[0014] 1. A kitchen sewer anti-backflow design method, in the installation of the kitchen sewer, a disc valve control device is added between the main sewer pipe and the elbow under the basin to prevent the backflow of sewage, so that the kitchen sewer is mainly composed of the main sewer pipe , disc valve, elbow, basin and other structures. For the bottom floors of high-rise buildings, the kitchen sewer adopts an anti-backflow design. Whenever people are away from home for a long time or when backflow occurs, the disc valve is closed in time to prevent the backflow from happening, and the sewage in the main sewer pipe will rise further, thereby increasing High pressure, when the pressure reaches a certain level, it will be more natural and unobstructed.

Abstract
The invention discloses an anti-backflow design method for a kitchen sewer, and belongs to the field of water supply and sewerage engineering. The anti-backflow design method mainly includes the steps that a butterfly valve control device is additionally arranged between a main sewer pipe and a bend below a wash basin in the kitchen sewer installing process, and is used for preventing backflow of sewerage, and the kitchen sewer is mainly formed by structures of the main sewer pipe, a butterfly valve, the bend, the wash basin and the like accordingly. The anti-backflow design method has the advantages of being easy to operate, low in cost, good in effect and the like, and can be widely used for preventing backflow of the kitchen sewer.
Description
technical field [0001] The invention relates to a design method for backflow prevention of a kitchen sewer, which belongs to the field of water supply and drainage engineering. Background technique [0002] At present, there are more and more high-rise buildings. Due to the thin pipes, unreasonable design of the bends, and the accumulation of debris, especially in the cold season, due to the influence of easy agglomeration of oil pollution, the sewer pipes are easy to accumulate and block at the sharp bends at the bottom, resulting in poor sewage discharge. Therefore, due to the blockage, the sewage will accumulate in the pipe and flow back to the lowest building connected with the main sewer pipe. Especially sometimes when there is no one at home for a long time, a large amount of sewage will enter and the residents will suffer. How to prevent the anti-backflow of the kitchen sewer has become a difficult problem to be solved urgently for this reason. [0003] The object of...
