DISTRIBUTING VALVE FOR CONCRETE PUMP AND THE CONCRETE PUMP

摘要

A distributing valve for a concrete pump and the concrete pump are provided, the distributing valve comprises a valve body (200) and a valve core (300), and a delivering cavity (213) is internally formed in the valve body (200) and is provided with a material inlet, a material outlet (212) and material suction openings (251,252). The material outlet (212) is communicated with a delivery pipe and the material suction opening (251,252) is communicated with a delivery cylinder (500). The valve core (300) is a L-shaped pipe formed by a first pipe section (310) and a second pipe section (320), and one end of the L-shaped pipe is connected with a hopper (600) and a revolution fitting surface is formed between the end face of the other end of the L-shaped pipe and the internal face of the valve body (200). The valve core (300) is driven by a driving mechanism (400) and can be switched between a first position and a second position. Compared with the prior art, the distributing valve enjoys the technical effects of simple structure, high reliability, long service life and low manufacturing cost and can meet the demand of delivering concrete slurry under high pressure while reducing power consumption and retaining fine suction capability.
