High-speed double-circulation dialysate supply device

The utility model discloses a high-speed double-circulation dialysate supply device which solves the technical problems that a U-shaped connector of a dialysate supply device in the prior art is complex in manufacturing process, high in cost, inconvenient in pipeline disassembly and low in flow speed. The device comprises a T-shaped cavity connector, a pipeline cavity in the T-shaped cavity connector is distributed in a T shape, and a concentrated liquid supply system output port, a dialysis machine input port, a concentrated liquid supply system liquid return port and a dialysis machine small circulation port are formed in the four side faces of the T-shaped cavity connector respectively. A first pipeline between the output port of the centralized liquid supply system and the input port of the dialysis machine is in a transverse horn shape; the second pipeline from the output port of the centralized liquid supply system to the liquid return port of the centralized liquid supply system is in a vertical trumpe
