Abstract

Le dispositif de mesure du différentiel de pression de la présente invention est généralement déployé sous la forme d'un limiteur de flux placé dans l'entrée de valve, de façon à créer une pression différentielle souhaitée pour signaler une valve pilote, par exemple, qui commande la valve principale, afin de limiter le débit à travers ladite valve. Le dispositif de mesure du différentiel de pression de la présente invention est déployé à travers l'orifice d'entrée de la valve, son axe central étant perpendiculaire à la direction d'écoulement du fluide. L'élément de restriction de flux de la présente invention peut être configuré dans une variété de tailles, afin de créer une section transversale restrictive souhaitée par rapport au flux, en créant ainsi les signaux de pression différentielle requis pour l'instrumentation et le contrôle de la valve. L'élément de restriction de flux est configuré avec des ouvertures en amont et en aval qui sont les ouvertures vers des passages menant aux orifices d'extrémité correspondants en amont et en aval. Les orifices d'extrémité fournissent des agencements de connexion pour le système de commande de l'instrumentation de la valve principale.
