1. Disassembly Safety When disassembling control valves, the maintenance manufacturer should formulate the correct sequence of operations in advance to avoid caused by improper operation, such as sudden detachment of parts. Use the appropriate tools, such as wrenches that match the size of nuts or bolts, to avoid damage tools or injury to personnel due to excessive force. For larger and heavier control valve components, such as valve bodies and actuators, use the appropriate lifting equipment for ho, and it is strictly forbidden to carry them by hand. During the hoisting process, Jiangyin Ouresi attaches great importance to the safety of lifting equipment such as the strength and reliability of hooks and lifting slings, and there should be a dedicated person to direct to ensure that the hoisting process is stable and accurate During the disassembly process, if you encounter parts that are difficult to disassemble, it is strictly forbidden to use brute force to disassemble them. You can use loosening agents or heating methods, but be sure to control the heating temperature to prevent parts from deforming or being damaged due to excessive heat. At the same time pay attention to ventilation to avoid harm to the human body from harmful gases produced by the evaporation of loosening agents.
