Self-adaptive galvanostat

The invention provides a self-adaptive galvanostat which comprises a pipe body, a first backflow hook plate and a second backflow hook plate, the pipe body comprises a liquid inlet, a liquid outlet and two pipelines communicated with the liquid inlet and the liquid outlet, and an obtuse angle is formed between the flow direction of the confluence position of the first pipeline and the flow direction of the flow direction of the second pipeline; the first backflow hook plate is fixed to the pipe body and arranged at the flow dividing position of the first pipeline and the second pipeline, and the first backflow hook plate is bent towards the first pipeline. A second backflow hook plate is fixed to the pipe body and arranged in the first pipeline, the second backflow hook plate is bent towards the upper wall of the first pipeline, under the condition of the same system and multiple branches, part of pipeline flow and flow speed are large, certain resistance eddy current is generated under the action of the back
