| Abstract: | Introduction The pressurizer proportional spray control valve is one of the key valves for PWR nuclear power plant and it is the only level 1 nuclear safety control valve in power station system. Mastering the technical characteristics of the valve has very important guiding significance for engineering and domestic research for the valve. Method Based on two typical structures used in domestic PWR nuclear power units - pneumatic V-ball proportional spray valve and solenoid angular proportional spray valve， this paper compared and analyzed them from structural design， working principle， operation and maintenance. Result Through analysis， it was concluded that the two types of proportional spray valves have different technical routes， but both can realize the spray control function required by the pressurizer system of nuclear power plant. Users can choose relatively suitable products according to the technical route and specific needs of nuclear power plant. Conclusion However， in the new nuclear power market in the future， the solenoid angle proportional spray valve was expected to have a broad application prospect. |
