A water purifier controlled by a four-way valve

Abstract

The invention discloses a water purifier controlled by four-side valves. The water purifier comprises an RO filter element and a pressure barrel. The pressure barrel is divided into a pure water area and a waste water area through a partition film of a flexible structure. Pressure is transmitted between the pure water area and the waste water area. The water inlet end of the RO filter element is connected with the first four-side valve. The water outlet end of the RO filter element is connected with the pure water area of the pressure barrel through a first check valve. The waste water end of the RO filter element is connected with the waste water area of the pressure barrel through the second four-side valve. The outlet water of the pure water area of the pressure barrel is connected with a water outlet faucet after sequentially passing through the first four-side valve, the second check valve and the second four-side valve. The waste water area of the pressure barrel is connected with a waste water ratio control valve. A power supply is omitted, energy is saved, the water purifier is suitable for outdoors or other places with water but no power, and the limit of sites is reduced; meanwhile, a pressure barrel gas bag is omitted, and the storage water volume of the pressure barrel is large; pure water is pressed out by waste water, and the water outlet stable flow is little changed.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, in particular to a water purification machine controlled by a four-sided valve. Background technique [0002] At present, RO water purifiers on the market are generally divided into charged RO machines and uncharged RO machines. Since the commonly used RO membrane needs to provide a pressure above 0.42MPa to operate water production, the charged RO machine generally has a booster pump to provide pressure, and other control valves that use electricity as energy. The live RO machine must be installed in a place with a socket, and the use site is limited. Since the whole machine is powered on, it needs to consume energy, and water and electricity run in the whole machine at the same time, there is a risk of water leakage. The uncharged RO machine is generally controlled by a four-sided valve or an electric booster mechanism. Since the four-sided valve needs pressure control, th...

The live RO machine must be installed in a place with a socket, and the use site is limited. Since the whole machine is powered on, it needs to consume energy, and water and electricity run in the whole machine at the same time, there is a risk of water leakage

The uncharged RO machine is generally controlled by a four-sided valve or an electric booster mechanism. Since the four-sided valve needs pressure control, the water volume of this RO mechanism is very small, and the pressure difference between the front and rear ends is too small when the tap water pressure is low, and the water production time is very long. It is not suitable for ordinary users, and when the water source pressure is less than 0.2MPa, it is basically impossible to produce water; when using a booster mechanism, due to the complexity of the booster mechanism, it is easy to cause water leakage, and the pressure tank is an inflatable tank, and the water source pressure is too small. The amount is too small
