Water supply system

Abstract

A water supply system for delivering water from a water inlet manifold to a water outlet manifold, comprises a first water inlet pipe, an air pressure water tank and a first water pump; the first water inlet pipe is connected to the water inlet manifold; the air pressure water tank is connected between the first water inlet pipe and a water suction pipe of the first water pump; a water outlet pipe of the first water pump is connected to the water outlet manifold; the air pressure water tank is provided with a preset first water level; and the quantity of gas compressed in the air pressure water tank allows a pressure inside the air pressure water tank to be an atmospheric pressure when water in the air pressure water tank is in the first water level.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Patent Application No. PCT / CN2017 / 000235 with a filing date of Mar. 17, 2017, designating the United States, now pending, and further claims priority to Chinese Patent Application No. 201610167576.6 with a filing date of Mar. 18, 2016. The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference.TECHNICAL FIELD[0002]The disclosure relates to the technical field of water supply, and particularly relates to a water supply system.BACKGROUND OF THE PRESENT INVENTION[0003]A non-negative pressure or superimposing pressure water supply device refers to a water supply device directly connected in series with a water supply pipe network. Briefly, a cabinet-type non-negative pressure water supply device is arranged between a water inlet manifold and a water outlet manifold; the non-negative pressure water supply device is furthe...

AI Technical Summary

Benefits of technology

[0008]The disclosure is an improvement on a cabinet-type non-negative pressure water supply technology, and aims to provide a water supply system which has the same effect as that of a cabinet-type non-negative pressure water supply device, but in which facilities among water inflow, water storage and water supply are simple to link and continuous in operation parameters.

Problems solved by technology

However, since water in the water tank is in an atmospheric pressure state, and therefore has a large pressure difference with a water inlet pressure; and storage time of water in the water tank has randomness due to water consumption so that the control of the device is excessively complicate, and parts of non-negative pressure container are lost neither.
