Abstract
A purified water supply pipeline system is provided. Source water flows from a source water inlet to a front filtration module, an inlet solenoid valve, a booster pump, and a main filtration module and is separated into purified water and waste water. The purified water flows through a first one-way valve to a rear filtration module and then flows to a purified water pipeline, on which a water outlet faucet is mounted. The waste water flows to a waste water pipeline, on which a waste water throttling element and a waste water outlet are disposed. The purified water also reflows to the main filtration module through a switch solenoid valve and the booster pump, to form a reflow pipeline. The purified water supply pipeline system balances concentration difference on both sides of the main filtration module. Accordingly, quality of the purified water and user experience are improved.
