Converging nozzle for vanadium redox flow battery

The utility model discloses a confluence nozzle for a vanadium redox flow battery, which belongs to the technical field of vanadium redox flow batteries, and comprises a fixed seat, a connecting pipe is fixedly connected to the upper surface of the fixed seat, a shell is sleeved on the surface of the connecting pipe, two movable boxes are fixedly connected to the surface of the shell, and the two movable boxes are fixedly connected to the upper surface of the fixed seat. According to the confluence nozzle for the vanadium redox flow battery, by arranging a sliding rod, a spring, a fixing ring and a first clamping groove, when the shell is fixed, a user pulls a handle to drive the sliding rod to move, meanwhile, the spring is compressed, then the shell is connected to the surface of a connecting pipe in a sleeving mode, and the connecting pipe is connected with the sliding rod in a sleeving mode; and after the first clamping groove corresponds to the sliding rod, the handle is loosened, so that the sliding rod
