safety valves
Overpressure release mechanisms
Safety valves are devices that automatically release pressure when it exceeds safe levels, preventing explosions in boilers, pressure cookers, and industrial equipment.
The term extends to any mechanism or practice that harmlessly releases tension before it becomes dangerous: Sports serve as a safety valve for aggression.
Institutions may tolerate minor dissent as a safety valve against revolution.
