Abstract

Un cierre de dos etapas, tal como un cierre de anillo, para su utilización en una línea de proceso presurizada, que tiene un miembro de cierre dinámico y un miembro de cierre estático. El miembro de cierre dinámico está configurado para acoplarse herméticamente de manera continua contra una superficie de cierre que se desliza a lo largo del miembro de cierre dinámico. El miembro de cierre estático está configurado para acoplarse herméticamente contra la superficie de cierre en respuesta a un aumento en la presión de fluido de proceso dentro de la línea de fluido de proceso, para aumentar la presión de cierre estático contra la superficie de cierre. El miembro de cierre estático también está configurado para liberarse de la superficie de cierre para minimizar la fricción con la superficie de cierre cuando la presión del fluido de proceso baja y/o en respuesta al movimiento de la superficie de cierre. El cierre de dos etapas puede usarse en configuraciones que requieren tanto un cierre dinámico como un cierre estático, tal como en algunas válvulas de control de proceso. Se describe una válvula de control de proceso que tiene el cierre de dos etapas.
