AI Technical Summary
In environments with poor gas quality at the end of the pipeline network, carbon black easily adheres to the valve stem and valve port of the gas pressure regulator, causing the valve port to not close tightly. If it is not cleaned for a long time, it will be damaged. Existing disassembly tools are inefficient and may raise carbon black, which is harmful to health.
A valve stem nut disassembly device was designed, including a rotating drum and a positioning rod. The bottom of the rotating drum has a disassembly hole that is adapted to the shape of the nut. The bottom end of the positioning rod has a positioning groove that matches the top of the valve stem. The top of the rotating drum has an adsorption component for adsorbing carbon black. The nut is disassembled by combining a handle and a sleeve structure.
It enables efficient nut removal in confined spaces, preventing carbon black from being blown out and protecting the health of workers.
