Description

Ball valve convenient to dismantle maintenance Technical Field The utility model relates to the technical field of valves, in particular to a ball valve convenient to detach and maintain. Background In an industrial fluid control system, a ball valve is used as a key cutting-off or adjusting device, is widely applied to the fields of petroleum, chemical industry, natural gas, water treatment and the like, and the core structure of the ball valve realizes the opening and closing of a flow passage through a rotary sphere, has the advantages of flexible operation, reliable sealing and the like, however, in the long-term operation process of the traditional ball valve, the problems of ageing of sealing elements, clamping stagnation of a valve rod, corrosion of a valve body and the like often occur due to medium corrosion, high-temperature and high-pressure environment or frequent opening and closing operation, so that the valve is leaked or cannot be normally opened and closed. Such faults not only affect production efficiency, but may also cause potential safety hazards; The maintenance of traditional ball valve usually needs whole dismantlement, even need cut off piping system, maintenance process is complicated and consuming time, for example, the valve body adopts flange or welding mode with the connection of pipeline more, need use specialized tool and destroy partial structure during the dismantlement, maintenance cost and downtime have been increased, in addition, partial ball valve inner structure is compact, the sealing member is changed difficultly, the maintenance personnel is difficult to accomplish the operation in limited space, further maintenance efficiency has been reduced, and among the current easy-to-detach's ball valve application, though dismantle through split type design convenient to carry out, but in whole use, the most important is sealed, although can guarantee convenient dismantlement in the constantly dismantlement and the installation of ball valve, still need guarantee certain leakproofness, and current easy-to-detach's ball valve leakproofness still seals with traditional sealing member, can lead to the leakproofness greatly reduced in continuous dismantlement and installation, for this reason, a ball valve convenient to dismantle maintenance is proposed.
