Abstract

Un obturador de tubo incluye dos o más cabezas de obturación conectadas de manera pivotante que funcionan en combinación para duplicar el bloque y purgar un tubo. Por lo menos una de las cabezas de obturación tiene un elemento de sellado expansible que se encuentra en comunicación con una fuente de inflación. El elemento de sellado puede ser un elemento de sellado inflable o un elemento de sellado de filtro de compresión. Una sección de pasaje puede pasar a través de la conexión de pivote y hacia la cabeza de obturación de la cual lleva el medio de inflación desde la fuente hasta el elemento de sellado. También se proporciona un pasaje de lumbrera de purga que pasa a través de la cabeza de obturación. La cabeza de obturación delantera puede incluir un elemento de limpieza para limpiar los restos delante del obturador. Las cabezas de obturación también pueden incluir una placa deslizable que acopla de manera deslizable la superficie interior del tubo para orientar de manera adecuada las cabezas de obturación dentro del tubo.
