Zusammenfassung:	The invention discloses an anti-dead volume pipe and a water flow control method. The anti-dead volume pipe comprises a mixing tank liquid inlet pipe (2), a Y-shaped tee (3), a first liquid outlet pipe (42), a first liquid outlet one-way valve (44), a second liquid outlet pipe (52) and a second liquid outlet one-way valve (54). The water flow control method comprises the following steps: firstly,controlling a second liquid to flow to the Y-shaped tee (3) through the second liquid outlet one-way valve (54); after the second liquid flows into the mixing tank liquid inlet pipe (2), controlling first liquid to flow to the Y-shaped tee (3) through the first liquid outlet one-way valve (44); when injection of the first liquid is completed, continuously controlling the second liquid to flow intothe mixing tank liquid inlet pipe (2). Through the anti-dead volume pipe and the water flow control method, the dead volume can be effectively reduced, influence of residual liquid is prevented, anda prepared solution has hig
