Description

Technical Field

[0001] The utility model relates to the field of the liquid inlet and outlet structure of a vanadium redox flow battery, in particular to a liquid inlet and outlet structure of a vanadium redox flow battery. Background Art

[0002] A vanadium redox flow battery is usually a device that can store and release electric energy. At the same time, a vanadium redox flow battery is an efficient electric energy conversion and storage device. When a vanadium redox flow battery is in use, a liquid inlet and outlet structure will be used.

[0003] In the patent application No. 202321547291.7, a corrosion-proof liquid inlet and outlet structure of a vanadium redox flow battery is mentioned, which includes a liquid flow frame, a bipolar plate installed on one side of the liquid flow frame, an insulating sleeve and an annular sealing gasket. A liquid through hole is axially drilled through the liquid flow frame in the thickness direction. A plurality of liquid through ports are radially drilled in the inner wall of the liquid through hole. A plate hole is drilled in the bipolar plate corresponding to the position of the liquid through hole. The insulating sleeve is sleeved on the inner wall of the liquid through hole. The insulating sleeve is respectively provided with liquid through small holes corresponding to each liquid through port. The annular sealing gasket is clamped between the liquid through hole and the plate hole.

[0004] Among them, the liquid inlet and outlet operation of the vanadium redox flow battery is carried out by using the liquid through hole, the liquid through port and the liquid through small hole. At the same time, the annular sealing gasket is used to seal between the liquid through hole and the plate hole. The sealing plate is located on the side of the liquid flow frame. The plate hole is drilled on the sealing plate. Then, the sealing plate squeezes the annular sealing gasket to seal the liquid through hole. The sealing plate is usually connected to the liquid flow frame by a plurality of bolts. However, after the annular sealing gasket is used for a long time, it will age and corrode. Therefore, it is necessary to replace the annular sealing gasket. Usually, a plurality of bolts need to be unscrewed, then the sealing plate is separated from the liquid flow frame, and then the annular sealing gasket is removed. At the same time, the insulating sleeve inside the liquid through hole is maintained. However, this method has the situation of disassembling and installing a plurality of bolts and using special tools, which leads to low disassembly efficiency of the sealing plate and affects the replacement efficiency of the annular sealing gasket. It is not convenient to remove and replace the annular sealing gasket, and there are certain limitations. Summary of the Utility Model
