Abstract
Un anillo de cierre perfeccionado para uso como asiento de válvula con margen de temperaturas ampliado, teniendo al anillo de cierre un cuerpo de metal duro formado con una parte de resalto cilíndrico, estando la parte de resalto definida por una superficie frontal circunferencial, una superficie trasera circunferencial opuesta, y dos extremos, un par de pestañas circunferenciales que se extienden desde la superficie trasera del resalto en cada uno de los extremos respectivos , temiendo cada pestaña un borde circunferencial radialmente espaciado de la superficie trasera de la parte de resalto, un nervio circunferencial que se extiende desde la cara frontal de la parte de resalto entre los extremos y que termina en una superficie de asiento circunferencial, siendo la anchura del nervio menor que la distancia existente entre dichos extremos de la parte de resalto, estando el anillo de cierre destinado a ajustar dentro de una garganta circunferencial socavada en una región de asiento de una válvula, teniendo tal garganta lados sustancialmente paralelos espaciados en una distancia mayor que la distancia que existe entre los extremos de la parte de resalto del anillo y una abertura más estrecha que la distancia existente entre los lados de dicha garganta, y estando el nervio del anillo de cierre destinado a extenderse a través de tal abertura de la garganta para aplicación de coincidencia móvil de la superficie de asiento del nervio con una superficie de cierre complementaria de tal valvular, cuyo perfeccionamientos comprenden: una garganta circunferencial que está formada en la superficie de asiento de dicho nervio, teniendo la garganta una abertura mas estrecha que la anchura de una parte interior de la misma y un anillo de asiento de material más blando que el metal del anillo de cierre, ajustando el anillo de asiento apretadamente dentro de la garganta del nervio y extendiéndose a través de la abertura de la garganta del nervio y más alla de la superficie de asiento del nervio para determinar en una superficie de asiento de válvula principal , estando dicha superficie de asiento de válvula principal de dicho anillo de asiento destinada a proporcionar la única aplicación de cierre con tal superficie de cierre de válvula complementaria, a no ser que la temperatura dentro de dicha válvula supere la temperatura de destrucción del material del anillo de asiento.
