Abstract

L'involucro della valvola a farfalla di strozzamento è costituito da un primo anello d'involucro (28), da un secondo anello d'involucro (29) e da un morsetto d'involucro (43), che fa presa tutt'intorno a questi due anelli d'involucro. Il morsetto d'involucro (43) è in due pezzi e comprende degli adatti mezzi di chiusura (48, 49), per collegare l'una all'altra con un accoppiamento dinamico le singole parti d'involucro. Una delle metà di morsetto d'involucro (46, 47) porta integralmente una mensola (44) per un servoelemento (9). Una forma d'esecuzione preferito comprende degli elementi di supporto a chiavistello girevole (34, 35), con i quali il primo anello d'involucro (28) e il secondo anello d'involucro (29) possono venire bloccati l'uno su l'altro.
