Water purification system

Abstract

The invention provides a water purification system. The water purification system comprises a pretreatment unit, a water outlet device, a first water purification branch and a second water purification branch, wherein the first water purification branch and the second water purification branch are respectively connected with the water outlet end of the pretreatment unit, and the water outlet end of the first water purification branch and the water outlet end of the second water purification branch are respectively communicated with the water outlet device. A water inlet solenoid valve, a pressure stabilizing pump and a reverse osmosis treatment unit are successively arranged on the second water purification branch in a serial connection mode. The water purification system further comprises a concentrated water backflow branch, wherein the first end of the concentrated water backflow branch is connected with a concentrated water outlet of the reverse osmosis treatment unit, and the second end of the concentrated water backflow branch is communicated with a water inlet of the pressure stabilizing pump by a tee joint. A one-way valve is arranged between the tee joint and the water inlet solenoid valve in a serial connection mode. The water purification system ensures that water can only flow from the water inlet solenoid valve to the pressure stabilizing pump through the one-way valve arranged between the tee joint of the concentrated water backflow branch and the water inlet solenoid valve in the serial connection mode, prevents the water inlet solenoid valve from suffering from frequent impact of fluctuating water pressure and prolongs the service life of the water inlet solenoid valve and the pressure stabilizing pump.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purification system. Background technique [0002] In the existing technology, during the working process of the water purification system, due to the pumping disturbance of the stabilizing pump or other abnormal fluctuations, it may cause the water inlet solenoid valve to emit an abnormal signal due to the pumping disturbance of the stabilizing pump or other abnormal fluctuations. The sound will affect the operating life of the water inlet solenoid valve and the regulator pump, and also affect the product experience. Contents of the invention [0003] The invention aims to provide a water purification system with an anti-impact water inlet solenoid valve. [0004] The invention provides a water purification system, comprising a pretreatment unit, a water outlet device, and a first water purification branch and a second water purification branch respectively connected...
