Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
As a valve type, diaphragm valves inherit the generic flow control function - they are designed to control fluid flow through a conduit. This function is shared with all valve types and is already established in the enriched valve class.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
Both source definitions clearly identify diaphragm valve as a type of valve (ISO 15926 states it's a MEMBRANE VALVE, which is itself a valve type). The parent_candidates list includes 'manual valve' which is already enriched, but 'Valve' is the more appropriate direct genus as it's the broader valve category. Valve is already enriched in our ontology with FlowControlFunction.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.ResilientDiaphragm ⊓ ∃hasComponentPartAtAllTimes.Port ⊓ ∃participatesIn.DiaphragmClosureProcess

Has a resilient diaphragm as closure member that is forced against a port to control flow.

The differentia captures the unique structural mechanism: a resilient (flexible) diaphragm that serves as the closure member and is forced against a port. This is the minimal condition that distinguishes diaphragm valves from all other valve types, which use different closure mechanisms.

These parts constitute the essential mechanism that defines a diaphragm valve: the diaphragm itself, the port it seals against, and the actuating mechanism that forces them together.

TransformationTransformação
flow rate modification through variable restriction
Like other valves, diaphragm valves have a single inlet and outlet with the same fluid, but the flow rate is controlled by the position of the diaphragm against the port, creating variable restriction.
Disjoint WithDisjunto com
BallValve GateValve ButterflyValve GlobeValve PlugValve
C1: BallValve, GateValve, ButterflyValve, GlobeValve, PlugValve. Disjoint with other valve types that use incompatible closure mechanisms - a valve cannot simultaneously use a diaphragm closure and a ball, gate, butterfly, globe, or plug closure mechanism.
