The knowledge of safety valve

Safety valves are automatic protective valves that exceed safe pressure in combustion or non-combustion pressure vessels and piping systems.

Relief or relief valves should be used in closed vessels or devices where the pressure is not atmospheric, and where, in some cases, the system pressure may exceed the design pressure.In some processes,such as media flow rate imbalance or energy input or output process can lead to equipment pressure over the operating pressure.If,for these or other reasons,the pressure exceeds the specified limit,it must be reduced through a relief valve or relief valve.
