Distributing valve for concrete pump and the concrete pump

A distributing valve for a concrete pump, the distributing valve comprising:

• a valve body (200) and a valve core (300), and a delivering cavity (213) is internally formed in the valve body (200) and the valve body (200) is provided with a material outlet (212), a material inlet and a first material suction opening (251), wherein the material outlet (212) is communicated with a delivery pipe and the first material suction opening (251) is communicated with a delivery cylinder, characterized in that, the valve core (300) is a pipe structure formed by a first pipe section (310) and a second pipe section (320) in the delivery cavity;
• the first pipe section (310) extends vertically, and is rotatably fitted with the material inlet;
• the second pipe section (320) extends transversely in the delivery cavity and its inner end is connected to the lower end of the first pipe section (310), and a revolution fitting surface is formed between the end face of the outer end and the inner wall surface of the delivery cavity (213);
• the fitting between the first (310) and second (320) pipe sections and the valve body (200) is seal fitting;
• the valve core (300) is driven by a driving mechanism (400) to be switched between a first position where the outer end of the second pipe section (320) is in communication with the first material suction opening (251) and a second position where the first material suction opening (251) is in communication with the material outlet (212) via the delivering cavity (213).
