Waste water valve and water purification equipment

Abstract

The invention relates to the technical field of water purification equipment, in particular to a waste water valve and water purification equipment. The waste water valve comprises a valve body, an adjusting piece and multiple valve needles; the valve body is provided with a water inlet cavity, a plurality of water distribution cavities, a water outlet cavity and a plurality of waste water holes, and one water distribution cavity communicates with the water outlet cavity through at least one waste water hole; the adjusting piece is arranged on the valve body to communicate the water inlet cavity with the at least one water distribution cavity; the valve needles are movably arranged in the corresponding water distribution cavities, the valve needles and the waste water holes are arranged in a pluggable mode, the valve needles have the closed state of being inserted into the waste water holes and the open state of being pulled out of the waste water holes, and the waste water ratio is adjusted by switching the water distribution cavities through the adjusting piece. The water distribution cavities are switched through the adjusting piece, different waste water ratios can be achieved, and the equipment can adapt to water quality differences in different areas; the valve needles are inserted into the waste water holes to clean dirt in the waste water holes, so that the purpose of self-cleaning is achieved, and the waste water holes are prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a waste water valve and water purification equipment. Background technique [0002] Due to the differences in the composition of groundwater quality, there are differences in water quality across the country. At present, the wastewater ratio of the water purifier is fixed, which cannot adapt to the differences in water quality across the country, which leads to the failure of the RO membrane to achieve normal life in areas with poor water quality and rapid pollution failure; while in places with good water quality, the same wastewater ratio is also There will be too much waste of fresh water resources. In addition, in areas with poor water quality, after long-term operation of the wastewater solenoid valve, it is easy to precipitate crystalline scale on the wastewater branch parts and block the wastewater hole, and the RO membrane will also be blocked and qu...
