Problems solved by technology

[0004] However, since the waste water plug or waste water solenoid valve has a fixed pore size, when the pressure in front of the reverse osmosis membrane changes, the discharge of concentrated water and pure water cannot be proportionally changed with the pressure in front of the membrane.
This will lead to an increase in the concentration polarization of the membrane surface or an increase in the discharge of concentrated water, reducing the life of the reverse osmosis membrane or the efficiency of water production

Abstract

The invention discloses a regulating valve which comprises a shell, a diaphragm and an elastic component. A channel is formed in the shell, wherein the first end of the inner wall of the channel is provided with a first flange, the second end of the inner wall of the channel is provided with a second flange, the inner wall of the channel is provided with a flow guiding groove which extends from the second flange to the first flange, and the flow guiding groove and the first flange are arranged in a spaced mode. The diaphragm is movably arranged in the channel. The elastic component is located between the diaphragm and the second flange to push the diaphragm to move towards the first flange. According to the regulating valve, the through-flow sectional area of the regulating valve changes along with change of water pressure. When the regulating valve is arranged in a water purifier, the regulating valve can regulate flow automatically according to the pressure on the front portion of an RO membrane, and therefore the water production efficiency and the service life of the RO membrane are guaranteed. The invention further discloses the water purifier provided with the regulating valve.

Description

technical field [0001] The invention relates to the technical field of household appliance manufacturing, in particular to a concentrated water regulator for a water purifier and a water purifier with the concentrated water regulator. Background technique [0002] With the improvement of people's living standards, the quality requirements for drinking water are getting higher and higher. Existing water purifying equipment all has better water purifying effect, improves people's quality of life. [0003] Existing water purification equipment is a lot, and the water purification effect of reverse osmosis water purifier is best especially. Traditional household reverse osmosis water purifiers all use the form of waste water plugs or waste water solenoid valves to control the discharge of concentrated water from the reverse osmosis water purifier. [0004] However, since the wastewater plug or wastewater solenoid valve has a fixed pore size, when the pressure in front of the r...
