Double-tank adjustable pipe network pressure-superposed water supply device

Abstract

The invention discloses a double-tank adjustable pipe network pressure-superposed water supply device which mainly consists of a filter, a backflow preventer, two bag type flow stabilization tanks, a water pump, a flow meter and a control cabinet. The two bag type flow stabilization tanks are connected in parallel, a tap water inlet pipe is connected with inlets of the flow stabilization tanks, each flow stabilization tank comprises a tank body and a rubber bag, the rubber bags are arranged inside tank bodies, breathers are arranged in the tank bodies and used for being in communication with outside air, the outer walls of the rubber bags are in contact with the air, the inner walls of the rubber bags are in contact with taper water, the tap water is completely isolated from the outside through the rubber bags, and the water amount is adjusted by utilizing the expandable-contractible performance of the rubber bags. The double-tank adjustable pipe network pressure-superposed water supply device has the advantages that the double-tank adjustable pipe network pressure-superposed water supply device can be directly and serially connected to a tap water pipe network to achieve supercharged water supply and energy-saving purpose, the arranged rubber bags enable the tap water to be completely isolated from the outside air, and the double-tank adjustable pipe network pressure-superposed water supply device has an intake water amount adjusting function, can eliminate the hidden danger of air pollution and has good using effect.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a double-tank adjustable pipe network superimposed water supply equipment. Background technique [0002] Pipe network superimposed water supply equipment does not need to set up pools, water tanks and can make full use of the pressure of the tap water pipe network, so it has the advantages of flexible and convenient installation, small footprint, energy saving and convenient management and maintenance, so it is widely used in residences, offices, shopping malls, schools, etc. Secondary water supply systems in other fields, but most of the pipe network superimposed water supply equipment on the market currently adopts the working principle of air supplementation to eliminate the negative pressure of the pipe network, which will cause negative pressure to supplement air and external dirt to be sucked in Polluted water quality is a potential safety hazard, and it is p...
