Design scheme research on key technologies of portable and efficient grinding equipment for high dose stop valves in the primary circuit of nuclear power plants

In the high-dose radiation environment of the primary circuit of nuclear power plants, there are problems such as low grinding efficiency and low automation level in the grinding and repair process of the sealing surface of the stop valve seat. Using the working principle of grinding repair and manual grinding technology experience, we extracted the key process parameters for automation control. We researched the design scheme of key technologies for automated grinding equipment. In addition, we provided a detailed description of the equipment’s performance, purpose, structure, and function.
