AI Technical Summary
In the existing technology, when maintaining and repairing gate valves, it is necessary to manually disassemble the valve plate, which is inefficient and difficult to maintain a vertical position, easily leading to bending and damage to the valve plate.
A gate valve plate disassembly device including a drive mechanism and an adjustment mechanism was designed. By rotating the turntable, lead screw and clamping assembly, the valve plate can be stably clamped and pulled out, avoiding bending.
It improves the efficiency of valve plate disassembly, prevents valve plate damage, and enhances stability and practicality in use.
