Abstract
Uno sconnettore idraulico con valvola automatica di presa d'aria. Lo sconnettore comprende un corpo cavo avente un raccordo di entrata ed un raccordo di uscita provvisti di rispettive valvole di ritegno; una membrana elastica soggetta ad una pressione differenziale è collegata ad un'asta di azionamento dell'otturatore di una valvola di scarico sul fondo dello sconnettore. Lo stelo della valvola di scarico è provvisto di un condotto che si apre in una camera di presa d'aria formata all'estremità dello stelo opposta a quella della valvola di scarico; la camera di presa d'aria comunica con l'esterno mediante una valvola automatica azionata in chiusura dallo stesso fluido in pressione.A hydraulic backflow preventer with automatic air intake valve. The backflow preventer comprises a hollow body having an inlet and an outlet fitting provided with respective check valves; an elastic membrane subjected to a differential pressure is connected to a shutter operating rod of a discharge valve on the bottom of the backflow preventer. The stem of the drain valve is provided with a duct that opens into an air intake chamber formed at the end of the stem opposite to that of the drain valve; the air intake chamber communicates with the outside through an automatic valve activated by the same fluid under pressure.
