Abstract

The pressurizer safety valve is a nuclear primary over pressure protection device in the reactor coolant system, and is one of the important equipment to ensure the safe operation of nuclear power plants. This article analyzes the functional principles, structural components, and other key technologies of spring type pressurizer safety valves and pilot type pressurizer safety valves widely used in nuclear power plants, and deeply analyzes the surge mechanism of spring type pressurizer safety valves, as well as the cold and hot state schemes of pilot type pressurizer safety valves, The relevant conclusions can be effectively used for the research and design analysis of pressure regulator safety valves, providing important references for the selection and design, production research and development, and design optimization of pilot operated pressure regulator safety valves in nuclear power plants.
