Abstract

Sistema di comando dell'attuatore di una valvola di regolazione della portata in cui la differenza misurata di pressione (SIMBOLO)p ai capi della valvola ed il valore QS di portata richiesta o di set vengono inviati in un blocco funzionale che realizza la relazione V(SIMBOLO)po.Qs/V(SIMBOLO)p = Cvs, ove (SIMBOLO)po è la caduta di pressione costante imposta ai capi della valvola per determinarne la curva caratteristica Cv in funzione delle diverse posizioni dell'otturatore della valvola stessa, detto valore di Cvs essendo inviato in un altro blocco funzionale che lo traduce in un valore di posizione del detto otturatore secondo la detta curva caratteristica, col quale comandare il detto attuatore della valvola.
