Bypass current breaker of double flow battery

The utility model discloses a bypass current interrupter for a double-flow battery, which comprises a cutoff mechanism and a temporary liquid storage mechanism, and the cutoff mechanism is arranged in a liquid storage tank, is positioned below a liquid inlet of the liquid storage tank and is used for receiving electrolyte; the temporary liquid storage mechanism is arranged below the cutoff mechanism and is used for receiving the electrolyte flowing out of the cutoff mechanism; the cutoff mechanism is further used for intermittently pouring the electrolyte in the cutoff mechanism into the temporary liquid storage mechanism, the cutoff mechanism is in a receiving state when the electrolyte is not poured into the temporary liquid storage mechanism, and the cutoff mechanism is in a pouring state when the electrolyte is poured into the temporary liquid storage mechanism; and the temporary liquid storage mechanism discharges the electrolyte in the temporary liquid storage mechanism to the liquid storage tank when t
