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.Manufacturing method of the French globe valve applying forging where a flow inlet and a valve base are formed within the French single seat valve; In the French double seat valve, a flow inlet, a valve base, a control base and a water outlet are formed, and they simultaneously have a central hole, the section of each neck is formed by a friction molten section, and the thickness of each section cast by friction is the same. With respect to molten convexities caused by friction melting, they can be eliminated. Procedure that allows to reduce the time of manufacture and save the cost of materials, in addition, decrease the percentage of defects and maintain the intensity of forging.
