Description

Technical Field

[0001] This utility model relates to the field of ball valve disassembly and assembly technology, and in particular to a two-piece ball valve that is easy to disassemble and assemble. Background Technology

[0002] In industrial pipeline systems, ball valves are widely used as key components for controlling the flow of media in fields such as water supply and drainage, chemical industry, HVAC, and oil and gas transportation. Traditional ball valves (such as one-piece or multi-piece structures) require regular maintenance, repair, or replacement of internal components (such as valve seats, balls, and gaskets) due to problems such as media erosion, seal aging, and component wear during long-term use. As industrial production continues to increase its requirements for equipment maintenance efficiency and cost control, the market urgently needs a ball valve design that balances sealing performance, structural stability, and ease of disassembly and assembly. Against this backdrop, the two-piece ball valve, which is easy to disassemble and assemble, has emerged.

[0003] However, early integrated ball valves, due to their integral valve body structure, required complete disassembly from the pipeline system during assembly and disassembly. This was not only time-consuming and labor-intensive, but also potentially led to extended downtime due to complex pipeline fixing methods (such as welding or large flange connections), severely impacting production efficiency.

[0004] Therefore, we provide a two-piece ball valve that is easy to disassemble and assemble to solve the above problems. Utility Model Content
