Abstract

La presente invención se refiere a una válvula de mariposa, que comprende un cuerpo que incluye un cubo anular que tiene extremos opuestos disponibles entre extremos espaciados de una línea de flujo y un cuello que se extiende del lado del cubo y teniendo una perforación a su través cuyo extremo externo está ampliado, un asiento de material elástico que tiene una pared interna sobre el lado interno del cubo, un disco que tiene una periferia externa para vincular estrechamente el asiento, un vástago que tiene un extremo interno que encaja estrechamente a través del asiento y hacia un agujero en el cubo, un extremo externo que encaja estrechamente a través del asiento y la perforación a través del cuello, y una porción entre sus extremos que se extiende a través del disco e incluyendo una parte no circular que encaja estrechamente dentro de una parte no circular del disco, con lo cual el disco puede girarse con el vástago entre posiciones abierta y cerrada por medio de un accionador conectado al extremo externo del vástago, el vástago siendo movible axialmente hacia y fuera de la posición de encaje estrecho dentro del cubo, asiento y disco, y medios que retienen el vástago en la posición mencionada, incluyendo una ranura alrededor del extremo externo de la perforación, una ranura alrededor del vástago, un primer anillo dividido que tienen bordes internos dispuestos de manera liberable dentro de la ranura alrededor del vástago y los bordes externos encajando estrechamente dentro del extremo externo de la perforación, y un segundo anillo dividido dispuesto de manera liberable en la ranura alrededor del extremo externo de la perforación y vinculando los lados externos del primer anillo dividido, el segundo anillo estando dividido en un lugar alrededor de su circunferencia para permitirle entrar y salir en forma de resorte de la ranura en la perforación.
