Pressure-superposed water supply device

Abstract

Provided is a pressure-superposed water supply device. When the device is used, firstly, compressed gas is filled in an air pressure chamber by an air charging device of an air pressure adjusting tank. When the device works, a water pump comes into operation, superposed pressurization is carried out on the basic of pressure of tap pressure, and pressure requirements of water are satisfied. Meanwhile, part of water enters a high-pressure water storage cavity of the air pressure adjusting tank through a water supply pipe and is stored. When water supply volume is decreased or the water is stopped, reserve water in the high-pressure water storage cavity returns to a water outlet main pipe from the water supply pipe through an air pressure principle, so that a system can retain needed pressure. When water intake pressure flow is not enough in the use of the device, the device adjusts flowing water flow of the water pump through a control cabinet, so that stability of the water intake pressure of the tap water is ensured. Meanwhile, the reserve water in the high-pressure water storage cavity automatically returns to the water outlet main pipe from the water supply pipe, water demands of users are satisfied, and the device is enabled to operate in an energy-saving mode. The purposes of automatically supplying the water and reducing labor installing intensity are achieved.

Description

technical field [0001] The invention relates to a laminated water supply equipment used in a water supply and drainage system, in particular to a pneumatic pressurized water supply equipment. Background technique [0002] The stacked water supply equipment in the prior art is generally equipped with a pressure tank on the water outlet main pipe of the water pump in order to save energy. The sub-chamber type stacked water supply equipment in the prior art is very troublesome to install and maintain, which increases the labor intensity of the equipment installation workers. When the tap water intake is insufficient, the water pump is used to pressurize the water supply from the adjustment tank configured by the equipment, which leads to a large power consumption of the equipment and poor energy-saving effect. Contents of the invention [0003] The purpose of the present invention is to design a pneumatic pressure-type superimposed water supply equipment, so that its regulati...
