[0002] In the operation of nuclear power plants, valves are one of the key components, and their performance stability is directly related to the safe operation of the entire nuclear power plant. As a result, modern industry has become increasingly strict in controlling the production quality of valves.

[0003] The existing nuclear power valve production measurement and control system mainly relies on traditional automated control technology. It controls the production process by setting fixed production equipment working parameters, production processes and production environment parameters.
