UNIVERSAL THERMO-HYDRAULIC DISTRIBUTOR Russian patent published in 2018 - IPC F24D3/02 F24D3/00 

FIELD: machine building.

SUBSTANCE: universal thermohydraulic distributor comprises cylindrical body 1 made in the form of a distributing manifold 2 and collecting manifold 3 with identical diameters D1. Distribution manifold 2 comprises branch pipe for connection of the source 4 supply pipeline with diameter D2 and branch pipes for connection of the consumers' supply pipelines 5. Collecting manifold 3 comprises branch pipe for connection of the source 6 return pipeline with diameter D2 and branch pipes for connection of the consumers’ return pipelines 7, at that, the branch pipes diameters D2 for connection of the source supply pipeline 4 and for connection of the source 6 return pipeline are identical. At the distributing manifold 2 free end, the air removal branch pipe 8 is arranged, at the distributing manifold 2 connecting end the first connection branch pipe 9 is located. On the of the collecting manifold 3 free end the slurry removing branch pipe 10 is arranged. At the collecting manifold 3 connection end the second connecting branch pipe 11 is arranged. To the first connecting branch pipe 9 the pump 12 is connected with its suction side, the pump 12 pressure side is connected to the second connecting branch pipe 11. To the pump 12 variable frequency drive 13 is connected, connected to the electronic controller 14 output, which input is connected to the differential pressure sensor 15 output, which first input is connected to the branch pipe for the source 4 supply pipeline connection, and the second input is connected to the branch pipe for the source 6 return pipeline connection. At that, the branch pipe for the source 4 supply line connection, distributing manifold 2, first connection branch pipe 9, pump 12, second connection branch pipe 11, collecting manifold 3 and the branch pipe for the source 6 return pipeline connection form the source circuit. Nominal head at the pump 12 zero feed rate H_n0 and the pump 12 flow-through part nominal resistance S_n0 are chosen from the condition of equation fulfilling Δh₀=(S_UTGD+S_n0)∙G₀²-H_n0 and, at that, finding the piezometric marks difference value between the branch pipe for the source 4 supply pipeline connection and the branch pipe for the source 6 return pipeline connection Δh₀ in the range from 0 to 1.5 w.c.m., where S_UTGD is the universal thermohydraulic distributor source circuit nominal hydraulic resistance in the rated mode, m⋅s²/kg²; G₀ is the water flow rate through the pump at the nominal mode, kg/s. Distributing manifold 2 and the collecting manifold 3 diameter D1 does not exceed the diameter D2 for the source 4 supply pipeline connection and for the source 6 return pipeline connection.

EFFECT: disclosed is the universal thermohydraulic distributor.
