Abstract
The safety valve is a common safety discharge device in natural gas station and pipeline
which plays an important role on overpressure prevention in gas supply systems. Based on the working principle and classification of current safety valves
some basic performance requirements for safety valves in the field of gas engineering were analyzed
taking into account the specific characteristics of natural gas. Finally
some questions and precautions in the selection and design of safety valves were discussed.
