Urban water supply system

Abstract

The invention provides an urban water supply system, and belongs to the field of water supply systems. The urban water supply system comprises a steady flow compensation tank, a variable frequency pump, a variable frequency controller and a user pipe network. The steady flow compensation tank, the variable frequency pump and the user pipe network are connected in sequence through a pipeline, the variable frequency controller is electrically connected with the variable frequency pump, and an inlet of the steady flow compensation tank is connected with a tank body used for filtration. The tank body comprises a water inlet, a water outlet and a drain outlet, the tank body is of a three-way pipe structure, a tank cover is detachably arranged on the drain outlet, the water inlet is in pipelineconnection with an urban water supply pipeline, the water outlet is connected with an inlet pipeline of the steady flow compensation tank, and a filter screen is arranged in the tank body. The tank body of the urban water supply system has a filtration function and can filter out large granular materials such as sediment and large molecular organic matter in urban inlet water, so that the qualityof urban water flowing out of the water outlet can reach the standard of purified water, and the safety and reliability of the water used by users are guaranteed.

Description

technical field [0001] The invention relates to the field of water supply systems, in particular to a municipal water supply system. Background technique [0002] There is a professional term for municipal water supply called urban water supply system, which is explained in Baidu Encyclopedia. Urban water supply system is an integral part of urban public utilities. Urban water supply system planning is an integral part of urban overall planning. Urban water supply systems usually consist of water sources, water pipelines, water plants and water distribution networks. After the water is taken from the water source, it is sent to the water plant for water treatment through the water delivery pipe, and the treated water is pressurized and sent to the user through the water distribution network. Most cities now adopt a unified water supply system. The unified water supply system is to use the same system to supply water for life, production, fire protection, and municipal use ...

Problems solved by technology

[0003] Taking the community as an example, the municipal water is generally not filtered. For example, "A Secondary Water Supply System" with application number CN201520574674.2 has no filtering device in the system and relies on the steady flow compensation tank Simple precipitation is carried out, and after precipitation, it is discharged through the sewage outlet. However, the steady flow compensation tank cannot be disassembled, and it is difficult to clean. After long-term use, there will be impurities in the subsequent water, which will affect the user experience.
