Abstract

Un dispositivo de regulacion de fluido incluye un disco de válvula y un puerto de válvula adaptados para suministrar un sello secundario durante una operacion de cierre por obstruccion, con el cual el disco de la válvula se vincula directamente conun componente de carcasa del puerto de la válvula para maximizar la integridad del sello secundario y ventajosamente reducir el tamano y complejidad de los puertos de válvula existentes. El puerto de válvula comprende una carcasa y un cartuchodispuesto de manera deslizable en la carcasa. El disco de la válvula se vincula directamente con un asiento primario dispuesto en el cartucho durante le operacion de cierre normal. Durante una operacion de cierre por obstruccion, sin embargo, elcartucho es empujado al interior de la carcasa de modo que el disco de la válvula calza directamente en el asiento secundario que se encuentra en la carcasa en una ubicacion aguas abajo del cartucho.
