Municipal water supply system

Abstract

A municipal water supply system is disclosed; a water feeding total pipe is connected to a steady flow tank water inlet formed in the top of a steady flow tank; a pressure limiting protective device and a vacuum suppressor are arranged on the top of the steady flow tank; a steady flow tank outlet formed in the bottom of the steady flow tank is connected to one end of a water discharging branch pipe through a water pipe, and the other end of the water discharging branch pipe is connected to a water discharging total pipe; a butterfly valve, a pressure transmitter, a water pump, a noise elimination check valve, and a butterfly valve are successively arranged between an end connected to the water pipe, of the water outlet branch pipe and an end connected to a water discharging total pipe, ofthe water discharging branch pipe; a pressure gage, a diaphragm air pressure tank, and a safe valve are arranged on the water discharging total pipe; and a bypass pipe is arranged in parallel to the water discharging branch pipe. The special independent research and development anti-vacuum suppression system has the vacuum suppressor, the pressure limiting device, and an anti-backflow device, canbe safely and directly connected to a tap water pipeline to achieve pressure-superposed water supply, and will not cause negative pressure of a municipal tap water pipeline.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a municipal water supply system. Background technique [0002] With the rapid development of urbanization in my country and the continuous expansion and renovation of urban buildings, the pressure of the original urban primary water supply pipe network is obviously insufficient, and most cities generally have insufficient water supply pressure for high-rise buildings during peak periods. At present, the usual solution at home and abroad is to add secondary pressurization equipment, but as people's requirements for drinking water quality and safety are getting higher and higher, the traditional secondary water supply has exposed its many shortcomings. [0003] Traditional secondary water supply equipment mainly has the following problems: [0004] (1) The pressure of the municipal pipe network cannot be fully utilized, which is not conducive to energy saving; [0005] (2) T...

AI Technical Summary

Problems solved by technology

[0004] (1) The pressure of the municipal pipe network cannot be fully utilized, which is not conducive to energy saving;

[0005] (2) The water pump head is high and the operation noise is large;

[0006] (3) Building a pool or water tank increases the floor area, increases investment, and has a long construction period;

[0007] (4) The disinfection facilities of the storage tank are not perfect, the water needs to be cut off when the tank is cleaned and disinfected, and the disinfection method is backward (poor effect);

[0008] (5) The water quality may be polluted after the water source passes through the concrete pool;

[0009] (6) The flow-passing parts (pumps, pipes, valves, etc.) of traditional water supply are mostly made of cast iron, and the phenomenon of running, popping, dripping, leaking and seepage in the pump room can easily cause corrosion of flow-passing parts and secondary pollution ;

[0010] (7) The volume of the fire-fighting and drinking water storage pool is too large, the water cycle is long, bacteria are easy to breed, and water quality cannot be guaranteed
