Abstract

Un sistema di lubrificazione per la sede di valvola di bloccaggio e trafilamento di una valvola a saracinesca. La lubrificazione è realizzata sulla sede attraverso un tubo che comunica con l'esterno della valvola a saracinesca onde alimentare il lubrificante e i canali interni della sede di valvola. Gli elementi di tenuta della sede di valvola mantengono il lubrificante entro i canali interni della sede. Il sistema di lubrificazione consente all'utilizzatore di controllare l'integrità di ogni sede senza esporre l'intera valvola all'atmosferica aumentando la pressione del lubrificante attraverso la sede di valvola.
