Water tank adjustment and storage variable voltage transformation pipe network pressure-superposed water supply device

Abstract

The invention discloses a water tank adjustment and storage variable voltage transformation pipe network pressure-superposed water supply device which mainly consists of a stainless steel water tank, a water level sensor, a water pump, a flow meter, an air pressure water tank and a control cabinet. The stainless steel water tank is arranged in front of a water suction header pipe of the water pump, a tap water inlet pipe is connected with a water inlet of the stainless steel water tank through a water tank control valve, a water outlet header pipe of the water pump is connected to a water using point for water supply through the flow meter and a user pipe network, the flow meter is used for detecting water using amount and feeds the water using amount back to the control cabinet, the control cabinet determines a corresponding pressure value according to a characteristic curve model of the user pipe network and uses the pressure value to conduct pressure control of the water outlet header pipe of the water pump. The water tank adjustment and storage variable voltage transformation pipe network pressure-superposed water supply device has the advantages of being large in adjusting flow, good in water supply safety, efficient in operation, capable of saving energy, low in cost and the like and being suitable for the occasions of long user pipe network or often insufficient pressure of a tap water pipe network or interrupted or insufficient flow.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a water tank storage variable pressure variable pressure pipe network superimposed water supply equipment. Background technique [0002] With the development of social science and technology and the improvement of people's living standards, the safety and energy saving of secondary water supply has become an issue of increasing concern to the society. The adjustment volume is small, and the safety of water supply is low. When the pressure of the tap water pipe network is often insufficient or the flow is intermittently insufficient, it will not work normally and affect the use. Contents of the invention [0003] The purpose of the present invention is to provide a water tank with large adjustment capacity, energy saving and safe water supply, which is a variable pressure variable pressure pipe network superimposed water supply equipment. [0004] The technical s...
