Abstract

The invention provides a concentrated water discharge solenoid valve with a washing function. The concentrated water discharge solenoid valve comprises a valve seat, an action unit and a coil unit, and further comprises a washing needle, wherein a restriction hole is formed in the valve seat; the action unit is mounted on the valve seat; the coil unit is respectively connected with the valve seat and the action unit; the washing needle is arranged at the tail end of the action unit; and the washing needle penetrates through the restriction hole. The fouling and plugging resistant solenoid valve disclosed by the invention can automatically clean the restriction hole, and is especially suitable for being applied to a high scale forming tendency and a high fouling and plugging tendency.

Description

technical field [0001] The invention relates to a water treatment unit for concentrated water discharge, in particular to a concentrated water discharge solenoid valve with flushing function. Background technique [0002] Due to the need to limit the flow of wastewater, the flow limiting aperture of the concentrated water discharge solenoid valve of the water treatment unit is very small. During the long-term operation of the pure water machine, impurities in the wastewater will block the flow limiting hole of the solenoid valve, causing the wastewater to fail. Emissions seriously affect the normal operation of the unit. Since the flushing solenoid valve for reverse osmosis concentrated water flow has the structural characteristics of the above-mentioned extremely small restrictor, it often occurs that the concentrated water discharge resistance increases due to scaling, and the insufficient membrane surface flow rate caused by the increased discharge resistance causes the m...
