Water supply device and water supply method

Abstract

The invention relates to the technical field of municipal water supply and drainage, in particular to a water supply device and a water supply method. The water supply device comprises a water tank and a liquid level sensor, wherein the liquid level sensor is used for measuring the liquid level change in the water tank, the water tank communicates with a water supply pipeline through a water conveying pipeline, and a control valve is arranged on the water conveying pipeline. According to the water supply device, the liquid level change in the water tank is determined by the liquid level sensor, a control valve is controlled so as to provide different water supply modes in the peak water supply time and the idle water supply time, when the water supply time is idle, the amount of secondary water supply is small, intermittent water supply is performed on the water tank by controlling the control valve, additionally, the water tank is replenished to the preset liquid level in the set time period before the water supply peak time, then water supply is stopped, the water storage capacity of the water tank is fully utilized, and the problem that water supply of the water tank is cut off due to serious pressure relief of a pressure relief area of the water tank because the liquid level in the water tank is low due to large water amount of secondary water supply at the water supply peak time is solved.

Description

technical field [0001] The invention relates to the technical field of municipal water supply and drainage, in particular to a water supply device and a water supply method. Background technique [0002] Secondary water supply refers to the form that units or individuals store and pressurize urban public water supply or water supply from self-built facilities, and then supply it to users or for their own use through pipelines. The secondary water supply is mainly established to compensate for the lack of pressure in the municipal water supply pipeline and to ensure the water use of people living in high-rise buildings. It is closely related to the normal and stable life of the people. Whether the secondary water supply facilities are constructed, designed and constructed in accordance with the regulations is directly related to the secondary water supply. Water quality, water pressure and water supply safety, compared with the urban raw water supply, the water quality of the...

Problems solved by technology

[0005] The purpose of the present invention is to provide a water supply device and a water supply method to solve the problem that the water inlet valve of the existing water storage tank is in the normally open mode. On the one hand, the water storage volume of the water tank cannot be fully utilized; The liquid level in the water tank is low, causing severe pressure relief in the direct supply area, and even leading to water cutoffs
