Patent

CA 2619482

The present invention provides more efficient, cost effective coke drum isolation valve devices and system as well as more efficient, cost effective methods for isolating the flow of matter from location to another in the delayed coker unit operation where the valve comprises a first seat; a second seat aligned with said first seat; a blind; a main body having an orifice dimensioned to align with an orifice in said line; wherein said main body is coupled to said line; an upper and lower bonnet coupled to said main body, wherein said bonnets may be removed in order to replace valve parts without separating the main body from the line; and a plate located inside a bonnet, wherein the plate comprises a planar surface that contacts a surface of the blind.

La présente invention concerne des dispositifs et un système de vannes d'isolation plus efficaces et plus économiques pour unités de cokéfaction ainsi que des méthodes plus efficaces et plus économiques d'isolation du flux de matériau d'un point à un autre dans l'unité de cokéfaction différée. La vanne comprend un premier siège; un second siège aligné sur le premier; un obturateur; un corps principal dont l'ajutage est dimensionné pour s'aligner sur un ajutage de la canalisation, ledit corps principal étant raccordé à ladite canalisation; des coiffes supérieure et inférieure raccordées au corps principal qui peuvent être déposées pour le remplacement de pièces de vanne sans séparation du corps principal de la ligne; et une plaque située à l'intérieur de la coiffe dont la surface plane est en contact avec l'obturateur.
