Abstract

Essi consistono nella realizzazione di un foro o di un intaglio di comunicazione del fluido che riempie il passaggio a gomito dell'interno della sfera (3) della valvola, con l'esterno della stessa, nella zona opposta a quella dello sbocco del fluido, dove si trova un fermo (6) posto in posizione parallela rispetto ad una guarnizione (5). Quando la valvola è in posizione chiusa, la pressione del fluido fa aderire la sfera (3) alla guarnizione (5), eliminando le perdite.La comunicazione può essere raggiunta praticando un foro (13) nella parete della sfera (3), su un lato della sezione di sbocco del passaggio a gomito (7) della sfera (3).La detta comunicazione può essere raggiunta anche per mezzo di un foro o canale (15) ottenuto nello stesso fermo (6), oppure nella parete del corpo della valvola (1), sotto la zona della sede del fermo (6).Figura 1
