Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
SafetyReliefFunction ⊑ DesignedFunction
Realized in
SafetyReliefProcess ⊑ PlannedProcess
The identity-giving function combines both safety valve function (protection against overpressure) and relief valve function (pressure relief). This dual function distinguishes it from valves that provide only one of these capabilities.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
Safety relief valve is a specialized type of valve. While the ISO definition mentions it inherits from both SAFETY VALVE and RELIEF VALVE, the more fundamental genus is Valve since both safety valves and relief valves are valve subtypes. Valve is already enriched in our ontology.
3 Differentia SpecificaDiferença Específica
∃bearerOf.SafetyReliefFunction

Bears a safety relief function that combines both safety protection and pressure relief capabilities.

The SafetyReliefFunction is the minimal differentiating condition that captures the dual nature specified in the ISO definition - it must perform both safety and relief functions, distinguishing it from valves that perform only one of these functions.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Safety relief valves require specialized internal mechanisms to perform dual functions of safety protection and pressure relief, beyond the basic valve components.

pressure reduction through controlled discharge for safety protection
