Abstract

Se describen válvulas de retención que tienen un sello primario y un sello secundario, en donde los sellos primarios y secundarios resisten el movimiento de un fluido a través de la válvula de retención y el sello secundario puede proveer un sello de respaldo en un caso en donde la válvula de retención no funciona como se pretende. Los sellos primarios y secundarios pueden ser formados por primeras y segundas aristas de sellado, respectivamente y un cuerpo de válvula se puede colocar dentro de la válvula de retención, entre un soporte de válvula, la primera arista de sellado y una segunda arista de sellado. El cuerpo de válvula es configurado para moverse con respecto a las primeras y segundas aristas de sellado y puede tener una posición en donde una porción del cuerpo de válvula se acopla contra cualquiera de las primeras y segundas aristas de sellado.
