Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tooling technology, specifically to an online disassembly and assembly tooling for a high-temperature ball valve. Background Technology

[0002] The main reasons for choosing ball valves during maintenance are: ball valves can achieve full-bore flow, which is beneficial for situations requiring rapid system evacuation or filling during maintenance; ball valves are easy to operate, open and close quickly, and are convenient for remote control, allowing for rapid system switching and adjustment, thus improving work efficiency; ball valves have excellent sealing performance, are tight and reliable, and are not prone to corrosion of the valve sealing surface, ensuring the system's tightness during maintenance and preventing leaks and other potential problems; ball valves are suitable for diameters ranging from a few millimeters to several meters, and are suitable for environments from high vacuum to high pressure, making them applicable in various maintenance scenarios.

[0003] However, ball valve maintenance also has its drawbacks, mainly in the following aspects: If a ball valve malfunctions or is damaged, it can easily lead to fluid leakage in the pipeline system, affecting the normal operation of the system and even potentially causing safety accidents; damage to the ball valve can result in inaccurate fluid control, with the valve unable to be fully closed or opened, affecting the normal operation of the pipeline system; ball valve malfunctions may cause the valve to jam, preventing it from opening or closing properly, further affecting the normal operation of the pipeline system; when the ball valve seat is not properly sealed or the ball and seat are severely worn, it can lead to air leakage, affecting the normal operation of the pipeline system.

[0004] In existing technologies, common methods for ball valve maintenance include replacing seals, cleaning and grinding the valve body and seat, and repairing or replacing parts. If the sealing surface or gasket of the ball valve is aged or damaged, it needs to be replaced to resolve leakage problems caused by poor sealing. After long-term use, the valve body and seat may wear or accumulate impurities, requiring cleaning and grinding to ensure proper valve operation and sealing. If the valve is stuck due to foreign object blockage, valve stem misalignment, or worn sealing surfaces, repair or replacement of relevant parts is necessary. This typically involves removing foreign objects, adjusting the valve stem, or replacing worn parts.

[0005] When a valve experiences internal leakage, removing it from the pipeline for maintenance is relatively difficult and time-consuming. Therefore, there is an urgent need to propose an online disassembly and assembly tool for top-mounted high-temperature ball valves to solve the problems of slow maintenance and difficult disassembly and assembly in existing technologies.
