Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a repair tool for repairing a butterfly valve sealing ring. Background Art

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve features a disc-shaped closing element that rotates around a valve axis to open and close. The valve can be used to control the flow of various fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It primarily serves as a shutoff and throttling mechanism in pipelines. The opening and closing element of a butterfly valve is a disc-shaped disc that rotates around its axis within the valve body, achieving opening, closing, or regulating functions.

[0003] In the prior art, a butterfly valve is usually sealed with a sealing ring, which can improve the overall sealing performance of the butterfly valve.

[0004] However, after long-term use, the butterfly valve sealing ring is prone to aging and deformation. The butterfly valve sealing ring cannot fit tightly against the inside of the butterfly valve, which increases the leakage in the butterfly valve and reduces the reliability of the butterfly valve seal. The existing butterfly valve sealing ring repair tooling is difficult to repair butterfly valve sealing rings of different specifications, which is inconvenient for staff to actually operate and has low practicality.
