Tap water conversion valve

Abstract

The invention discloses a water purification change-over valve for a water tap. The water purification change-over valve comprises a connecting structure and an upper valve body, wherein the connecting structure is arranged inside a mounting hole formed in the upper end; the upper valve body can be hermetically butted with the water tap; a transition pipeline is arranged inside the upper valve body, wherein a water inlet of the transition pipeline communicates with the mounting hole; a water outlet of the transition pipeline communicates with the bottom surface of the upper valve body; the upper valve body is rotationally connected with a lower valve body; the lower valve body is internally provided with a purified water charging pipeline, a purified water discharging pipeline and a directwater discharging pipeline; the water inlets of the purified water charging pipeline and the direct water discharging pipeline communicate with the top surface of the lower valve body; when the lowervalve body rotates, the transition pipeline realizes butting and switching with the purified water charging pipeline and the direct water discharging pipeline; the water outlet of the purified watercharging pipeline and the water inlet of the purified water discharging pipeline communicate with the sidewall of the lower valve body; and the water outlet of the purified water discharging pipelineand the water outlet of the direct water discharging pipeline communicate with the bottom surface of the lower valve body. The water purification change-over valve for the water tap, provided by the invention, is simple in structure, low in fault rate and convenient to use and has the characteristics of ingenious design, simple production, low production and the like.

Description
