[0002] As an important fluid control device, butterfly valves are widely used in petroleum, chemical industry, water treatment, food processing and other industries. One of the core components is the sealing ring, which plays a key sealing role when the butterfly valve is closed, ensuring that the medium does not leak. The sealing performance of the butterfly valve is directly related to the safety and operating efficiency of the entire system. However, as a component that directly contacts fluid media for a long time, the sealing ring is prone to damage due to friction, high temperature or corrosion by corrosive media, and needs to be replaced regularly.

[0003] The existing butterfly valve sealing ring and butterfly valve with publication number CN221665305U includes a butterfly valve body, a through hole for installing a valve plate is provided in the butterfly valve body, and an embedded groove for installing a sealing ring assembly is provided at both ends of the butterfly valve body. The sealing ring assembly is fixed at both ends of the butterfly valve body through the embedded groove, and the combination design of rubber ring, gasket and self-tapping screw improves the fixing performance and sealing performance of the butterfly valve sealing ring. However, the device also has deficiencies in actual application. For example, the sealing ring directly contacts the liquid medium during use, which causes the sealing ring to be easily damaged. When the sealing ring is damaged, it must be replaced in time. However, the existing device usually needs to be disassembled from the pipeline as a whole before the sealing ring can be replaced. This process is complex, time-consuming and significantly increases the workload of the workers.

[0004] Especially in high-load scenarios where the sealing ring needs to be replaced frequently, the existing design of the butterfly valve is not flexible enough to meet the needs of quick assembly and disassembly and efficient maintenance. In addition, the current butterfly valve lacks adjustable flexibility in the assembly and disassembly of the connecting piece, limiting its adaptability in various installation conditions and further reducing maintenance efficiency.
