The invention discloses a manual split type multi-level water mixing softening valve which comprises an upper valve body and a lower valve body, wherein a valve body water inlet, a valve body water outlet and a valve body inner cavity are formed in the upper part of the upper valve body; the valve body inner cavity is provided with a valve core; the upper part of the valve core is connected with a rotating handle; a cavity is formed in the lower part of the valve core; one side of the cavity communicates with the valve body water inlet; a plurality of water mixing holes with different sizes are formed in the other side of the cavity; an inner water inlet and an inner water outlet are formed in the lower part of the upper valve body; the inner water inlet communicates with the valve body water inlet; the inner water outlet communicates with the valve body water outlet; the upper part of the lower valve body is connected with the lower part of the upper valve body; a central pipe and a softened water runner are arranged inside the lower valve body; the central pipe communicates with the inner water inlet; and the softened water runner communicates with the inner water outlet. According to the water mixing softening valve, a split type structure is adopted, the mounting and disassembly are convenient, and a resin tank is conveniently disassembled and changed; and the valve has a plurality of water mixing gears, so that the requirement of water mixing with different proportions is quite easy to meet.
