Description

Technical Field

[0001] The invention relates to the technical field of valve maintenance, and in particular to valve maintenance and disassembly equipment for a thermal power plant. Background Art

[0002] As a kind of pipeline fittings that help to open and close pipelines and control the flow direction, valves are commonly used to regulate and control the medium delivery. They have many functions. Because valves are inconvenient to replace, it is necessary to ensure the sealing and firmness of each valve on each pipeline during production. When the valve is in use, different media will cause different damages to the valve. In order to ensure the service life of the valve itself, the valve needs to be inspected regularly to ensure the safety of the valve when in use. However, most of the current disassembly equipment has a relatively simple structure. When in use, tools are usually needed to assist the user in the disassembly work. Due to the simple structure of the disassembly structure equipment, it is usually impossible to adjust. When facing the disassembly of valves at different heights and angles, it is necessary to replace different tools and move to different positions to disassemble the valve, which takes more time. In addition, due to the long-term conveying of the medium, the surface of the valve will produce more dirt, which makes the disassembly equipment easy to slip during the maintenance and disassembly work, and the torque cannot be applied well. Special cleaning takes more time, which delays the progress of the disassembly work. Therefore, we propose a valve maintenance and disassembly equipment for thermal power plants.
