Abstract

2.1 Con il dispositivo di bloccaggio, lo stelo della valvola può venire bloccato in una posizione terminale, per impedire un involontario azionamento della valvola. Una nota realizzazione presenta un dado a vite per il bloccaggio, il quale non si è confermato in condizioni di impiego ruvide, sporche. La nuova valvola non può essere adatta per tali condizioni di impiego.2.2 Un elemento a slitta (14) mobile trasversalmente allo stelo della valvola (4) serve come elemento di bloccaggio. Per il bloccaggio esso viene spinto tra una superficie di controsupporto (8) dal lato dell'involucro ed una superficie di applicazione (10) sullo stelo della valvola (4). L'elemento a slitta (14) porta un eccentrico (15) in una estremità. Con esso, l'elemento a slitta (14) può venire arrestato in una posizione di bloccaggio.2.3 Valvola per condizioni di impiego ruvide, sporche.
