Technical Field

[0001] This utility model belongs to the technical field of ball valve disassembly tools, and in particular relates to a ball valve disassembly and repair tool. Background Technology

[0002] Ball valves are a common type of valve. Their core component is a hollow ball, which is rotated to open and close the valve. The ball rotates 90 degrees around the axis of the valve stem, which can quickly cut off or connect the fluid in the pipeline. They are suitable for occasions that require frequent switching. Ball valves can not only effectively distribute media and change the flow direction, but also have excellent sealing performance to prevent media leakage. Due to their simple structure, convenient operation, good sealing performance and long service life, ball valves are widely used in various fields such as oil and gas pipelines, chemical industry, pharmaceutical industry, and municipal engineering.

[0003] Ball valves may be damaged during long-term operation, leading to a decline in sealing performance. Among these issues, aging of the sealing ring is the most common problem. During maintenance, the ball valve needs to be disassembled and the sealing ring replaced. However, due to long-term use, the sealing ring may adhere to the inner wall of the ball valve, making its removal difficult.

[0004] To address these issues, we provide a ball valve disassembly and repair tool. Utility Model Content

[0005] The purpose of this utility model is to provide a ball valve disassembly and repair tool. By moving a splitting blade in the gap between the ball valve and the sealing ring, the sealing ring is separated from the inner wall of the ball valve, which solves the problem that the internal sealing ring is not easy to remove when disassembling existing ball valves.
