Title (EN) TORQUE REDUCING VALVE SEAT
(FR) SIÈGE DE SOUPAPE DE RÉDUCTION DE COUPLE
Abstract:
(EN) A valve seat includes an annular sealing surface comprising a rubber-lubricant mixture; and a seat body. A valve includes a valve body; a valve element disposed within the valve body; and a valve seat comprising a rubber-lubricant mixture, the valve element configured to seal against the valve seat. A method for forming a valve seat includes mixing a raw rubber with a lubricant to form a rubber-lubricant mixture; placing the rubber-lubricant mixture into a mold configured to form a valve seat; and curing the rubber-lubricant mixture.
(FR) L'invention concerne un siège de soupape comprenant une surface d'étanchéité annulaire comprenant un mélange caoutchouc-lubrifiant ; et un corps de siège. Une soupape comprend un corps de soupape ; un élément de soupape disposé à l'intérieur du corps de soupape ; et un siège de soupape comprenant un mélange caoutchouc-lubrifiant, l'élément de soupape étant conçu pour se fermer hermétiquement contre le siège de soupape. Un procédé de formation d'un siège de soupape consiste à mélanger un caoutchouc brut avec un lubrifiant pour former un mélange caoutchouc-lubrifiant ; placer le mélange caoutchouc-lubrifiant dans un moule conçu pour former un siège de soupape ; et durcir le mélange caoutchouc-lubrifiant.
