Plastic pipeline applicable to municipal sewer, provided with self-cleaning structure and used for pollution discharging and water drainage

Abstract

The invention discloses a plastic pipeline applicable to a municipal sewer, provided with a self-cleaning structure and used for pollution discharging and water drainage, and relates to the technicalfield of water drainage projects, and aims to solve the problem that water flows cause the relatively great impact to pipelines. The plastic pipeline specifically comprises a pipe body; a flow slowingplate is arranged at one end of the pipe body and adopts the conical structure; a water drainage opening is formed in one end of the flow slowing plate; a flow equalizing plate is arranged on the inner wall, close to the flow slowing plate, of the pipe body; a water inlet is formed in the outer wall of one side of the flow equalizing plate; and a separating plate is arranged on the outer wall ofone side of the flow equalizing plate. According to the plastic pipeline, the structures such as the flow slowing plate, the flow equalizing plate and the like are arranged, water enters a tank body via the water inlet end of the pipe body, enters the flow equalizing plate through the flow slowing plate, enters the water inlet and is dispersed by water outlet grooves separated by the separating plate to flow out uniformly, flow slowing and flow equalizing are performed, the flow speed of the water flow is reduced, the impact caused by the water flow to the pipeline is reduced, the service lifeof the pipeline is prolonged, and output of the costs for maintenance, replacement and the like is reduced.

Description

technical field [0001] The invention relates to the technical field of drainage engineering, in particular to a plastic pipe for sewage and drainage with a self-cleaning structure for municipal sewers. Background technique [0002] The sewer is a kind of urban public facility, which appeared as early as the ancient Roman period. Generally speaking, the sewer system is used to collect and discharge the domestic wastewater generated in the city and the industrial wastewater generated in industrial production. At present, the sewers are all Round pipe, plastic pipe is widely used in gas pipes due to its good corrosion resistance, non-leakage, excellent flexibility, good resistance to scratches, fast crack transfer resistance, and long service life. , water supply pipes and oil pipelines, etc., have become the development trend of the plastic industry at home and abroad and are widely used. The inside of the plastic water pipe is smooth. Since the tap water cannot be discharged ...

AI Technical Summary

Problems solved by technology

The steady-state pipe with self-cleaning function in the above-mentioned patent has the following disadvantages: the flow rate of the liquid in the pipe is relatively fast, especially causing a large impact on the pipe transported longitudinally, reducing the service life of the pipe
