Water supply method and unit and device of same

Abstract

A water supply method is characterized in that two fluids with different densities are filled in a container 1. A basic unit of the water supply method comprises the container 1, and a pipeline 3 and a pipeline 4 are connected onto the container 1. Two basic units are arranged at different heights, one unit is that a first container 1 and a second container 2 are connected through the pipeline 3 and the pipeline 4, and the other unit is that a third container 11 and a fourth container 12 are connected through a pipeline 13, the third container 11 and a container 10 are connected through a pipeline 14. The water supply method and a unit and a device of the water supply method have the advantages that by means of the continuity of the fluids in the containers, the water supply device does not affect water pressure from a tap water pipe network and is not affected by water quantity of the tap water pipe network, and accordingly the safety of the pipe network and reliable water supply are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a water supply method and its unit and device. Background technique [0002] In urban buildings where tap water cannot meet the water supply pressure, it is often used. One method is to connect a water tank. This method consumes a lot of water pump energy and may cause secondary pollution; the other method is to use superimposed pressure or no negative pressure. At present, the main problem of this type of equipment is that it has a direct interaction with urban tap water. Contents of the invention [0003] The purpose of the present invention is to provide a water supply method. With this method, the original water pressure can be fully utilized, and the efficient operation of the water pump can be maintained to achieve the purpose of energy saving and pollution-free. This method does not affect the water pressure of the tap water pipe network, and is not affected by th...
