Tubular mixed-flow vertical pipe rainwater and sewage flow divider

Abstract

The invention discloses a tubular mixed-flow vertical pipe rainwater and sewage flow divider. The tubular mixed-flow vertical pipe rainwater and sewage flow divider comprises a flow divider shell, a rainwater outlet pipe is fixedly installed in the middle of the interior of the flow divider shell, the flow divider has the double functions of an overflow weir and the rainwater outlet pipe, the upper portion is a tubular overflow weir, the lower portion is the rainwater outlet pipe, and a circular intercepting groove is formed between the tubular overflow weir and the flow divider shell; and a flow guide inclined sheet is sealed at the bottom of the flow divider, a maintenance flushing pipe is fixedly installed on one side of the annular outer surface of the flow divider shell, a sewage outlet pipe is fixedly installed on the other side of the annular outer surface of the flow divider shell, and the sewage outlet pipe is provided with a control ball valve. According to the tubular mixed-flow vertical pipe rainwater and sewage flow divider, sewage intercepted in dry seasons is discharged into a residential quarter sewage pipe network, the tubular overflow weir and the valve are combined to control the flow in rainy seasons, meanwhile, the functions of quick air or water backwashing cleaning and quick sundry removal can be realized by the design of the maintenance flushing pipe, and the tubular mixed-flow vertical pipe rainwater and sewage flow divider has the characteristics of good effect, easiness in installation, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of rain and sewage diverters, in particular to a pipe-type mixed-flow riser rain and sewage diverter. Background technique [0002] At present, most residences implement the old version of water supply and drainage design specifications, and the balcony drainage is connected to the rainwater standpipe. Because some residents moved the washing machine to the balcony and added washing pools and wash basins, the rainwater standpipe mixed domestic sewage. With the promotion of the sewage project, the rain and sewage were diverted from the source, and the mixed-flow riser was transformed into the sewage system of the community. However, because the riser did not have flow-limiting measures, a large amount of rainwater from the sky was discharged into the sewage pipe network of the community, and the sewage channel was crowded. At the same time, due to the limited treatment capacity of municipal sewage plants, sew...
