Abstract: A volume liquid fixed-ratio multi-batch mixing valve includes a valve body, including a first inlet liquid chamber, a second inlet liquid chamber and a mixing chamber; a first valve core, controlling liquid inflow into the first inlet liquid chamber; a second valve core, controlling liquid inflow into the second inlet liquid chamber; a liquid drainage valve core, controlling liquid drainage; a rotary shaft includes a first impeller and a second impeller. The first impeller and the second impeller alternately control flow to the first inlet liquid chamber and the second inlet liquid chamber and to the second inlet liquid chamber and the mixing chamber. The first impeller and the second impeller are symmetrically about the rotary shaft; when the first inlet liquid chamber and the second inlet liquid chamber are communicated, the second valve core closes the second inlet liquid chamber and the mixing chamber.
