摘要：Safety valves, as major safety accessories of pressure systems, play a very important role in ensuring safe operation of chemical and energy installations. More precision and strict requirements have been put forward on the performance of safety valves as the result of harsher condition such as increased pressure and temperature. In order to develop advanced design, manufacturing and maintenance technology for safety valves, the state-of-the-art of safety valves was reviewed and key science and technology progresses were summarized, which include precision design of action and displacement, sealing design, seismic design, reliability design, high temperature mock-up testing verification and structural integrity and health monitoring and so on. On this basis, several future technical challenges were identified, including computer simulation of dynamic responses of safety valves under extreme fluid flows (higher temperature, higher pressure, earthquake, fire), testing setup and methods under extreme conditions, multi-scaling methods for determining the coefficient of flow, smart safety valve technology and structural integrity assessment of safety valves under extreme conditions. ? 2019, Chemical Industry Press.
