When faucet is opened, pressure release electromagnetic valve is closed, it is to avoid waste water enters pure water passage；When pure water faucet is closed, pressure release electromagnetism
Valve is opened, and carries out pressure release.
Used as other preferred, pure water pipe end setting pure water faucet, pressure release electromagnetic valve is time-delay closing electromagnetic valve, is received
Pure water faucet closing motion drives to be opened.When pure water faucet is closed, pressure release electromagnetic valve moment opens, and time-delay closing,
Carry out pressure release.
Preferably, the pure water faucet front side is provided with high-voltage switch gear, it is provided between high-voltage switch gear and pure water faucet
Water flow sensor and water outlet TDS probes.
Preferably, being provided with post active carbon filter element on the DI on rear side of the check valve, the pressure release bypass sets
Put on front side of post active carbon filter element.
Preferably, the primary filter filter element includes being disposed with PP cotton filter cores, preposition activated charcoal along water (flow) direction
Filter element.
Preferably, being provided with into water TDS probes between primary filter element and entering water electromagnetic valve.
Preferably, the waste pipe be provided with adjust waste water ratio proportioner and scouring electromagnetic valve, the proportioner and
Scouring electromagnetic valve is parallel with one another, and is arranged on the rear side of pressure release bypass.
The present invention is coordinated using check valve and pressure release electromagnetic valve, and the back pressure produced when pure water faucet is closed into water outlet is from letting out
Pressure bypass is to waste pipe pressure release, it is to avoid impact RO membrane cartridges, extends the service life of RO membrane cartridges.
