Abstract

Método de manufactura de la válvula de globo francesa aplicando forjadura donde dentro de la válvula francesa de asiento sencillo, se forman una entrada de flujo y una base de válvula; en la válvula francesa de asiento doble, se forman una entrada de flujo, una base de válvula, una base de control y una salida de agua, y tienen simultáneamente un agujero central, la sección de cada cuello se forma una sección fundida por rozamiento, y el espesor de cada sección fundida por rozamiento es el mismo. Con respecto a las convexidades fundidas causadas por la fusión por rozamiento se pueden eliminar. Procedimiento que permite a reducir el tiempo de manufactura y ahorrar el costo de materias, además, disminuir el porcentaje de defectos y mantener la intensidad de forjadura.
