Abstract

La presente invención se refiere a mejoras en válvula operada por fluido para dispositivos de control de flujo que tiene un cuerpo de válvula que incluye un pasaje de flujo y un anillo de asiento anular duro montado dentro del cuerpo de válvula alrededor del pasaje de flujo; un miembro de válvula reciprocable montado dentro del cuerpo de válvula para tener movimiento entre las posiciones abierta y cerrada relativas al pasaje de flujo y adaptado para asentar en posición cerrada sobre el anillo de asiento duro y para ejercer una fuerza de impacto contra el asiento duro cuando se asienta sobre el mismo, en respuesta a los cambios de presión de flúido; caracterizadas las mejoras en que el miembro de válvula comprende: un cubo central; un anillo de sello anular exterior duro que tiene superficies periféricas externa y radialmente internas que están radialmente separadas del cubo central para asentar en relación de contacto cara a cara con el anillo de asiento en la posición cerrada del miembro de válvula; y un miembro de conexión flexible que se extiende en una dirección generalmente radial entre el cubo y la superficie periférica radialmente interna del anillo de sello; el miembro de conexión se flexiona entre el cubo y la superficie periférica interna del anillo de sellamiento exterior después del contacto inicial del anillo de sello duro con el anillo de asiento duro para absorber las cargas de impacto que resultan del contacto del anillo de sello duro contra el anillo de asiento duro, sin movimiento substancial del anillo de sello duro.
