Electromagnetic three-path four-way valve for zero-discharge water purifier

Abstract

The invention belongs to the field of a water purifier and especially relates to a zero-discharge electromagnetic three-path four-way valve. An electromagnetic three-path four-way valve, a solenoid directional valve and a return water pressure tank are arranged as core components of a zero-discharge automatic washing water purifier. The electromagnetic three-path four-way valve is serially connected between a user water meter pipe and a domestic water pipe; under an electrifying water-making state, the solenoid directional valve is opened, the electromagnetic three-path four-way valve is closed and the electromagnetic three-path four-way valve is formed into a path A and a path B which are not communicated with each other; the path A is connected with the user water meter pipe and is used for supplying raw water to the water purifier; the water-making return water and automatic washing return water gathered in the return water pressure tank are communicated with the domestic water pipe through a return water supply pipe and are recycled as the domestic water by the path B; a check valve which has a shape of Chinese character 'Quan' and can be randomly arranged in flow direction and assembled is arranged in the electromagnetic three-path four-way valve, so that the path design according to different demands can be met; according to the technique of the electromagnetic three-path four-way valve and the solenoid directional valve, the one-pump multipurpose water purifier is realized and the problems of return water treatment and film blocking which puzzle the industry for a long time are solved.

Description

technical field [0001] The invention belongs to the field of water purifiers, in particular to an electromagnetic three-way four-way valve for non-discharge water purifiers. Background technique [0002] In the water purifier process, there is a lot of residual water after treatment. Because this residual water has been treated by three filter elements, it is very good domestic water. It is a great waste to discard it, and it is also difficult to recycle. Such as repeated filtration, increasing the water production rate, setting up another container for storage... In short, the troublesomeness of backwater treatment is self-evident. If it is directly discharged into the sewer, it is not a national policy to waste precious water. [0003] Purpose of the present invention, solve above-mentioned difficult problem exactly, open a kind of water purifier with non-emission and multi-purpose function of a pump to the society. Contents of the invention [0004] The invention belon...
