Abstract

SE ELABORA UNA VALVULA MECANIZANDO UNA OBLEO DE SILICIO (18) ENLAZADA A UNA OBLEA DE VIDRIO (2). ESTE MECANIZADO FORMA UNA MEMBRANA (44) Y UN ANILLO OBTURADOR. PARTE DE LA SUPERFICIE DE LA MEMBRANA (44) Y OPCIONALMENTE EL ANILLO OBTURADOR SE OXIDAN PARA PROPORCIONAR UNA PRETENSION MECANICA A LA MEMBRANA QUE MANTIENE LA VALVULA EN UNA POSICION CERRADA. ADEMAS SE PUEDE LLEVAR A CABO LA CORROSION (52) DE TAL MANERA QUE EN AUSENCIA DE DICHA PRETENSION LA VALVULA ESTA EN POSICION ABIERTA EN REPOSO.
