    摘要： Le robinet présente une structure qui le rend particulièrement bien adapté à une utilisation dans les circuits primaires de réacteurs nucléaires PWR.
    Un joint d'étanchéité 20 est interposé entre le corps 12 et un siège amovible 28. Le siège 28 est maintenu en place par un empilage comprenant une cage 36, des garnitures d'étanchéité 4, un fouloir 50, des rondelles élastiques 56, et une bride de fouloir 60. Le chapeau et la bride de fouloir 60 sont solidarisés avec le corps 12 par des tirants 130 et 132. La rotation de la tige 70 dans le sens anti-horaire permet l'extraction des garnitures d'étanchéité.

    摘要： @ A valve has a body (12) with a valve chamber (14) therein, an inlet (16) into the valve chamber, an outlet (18) from the valve chamber and an opening to the valve chamber aligned with the outlet, and a bonnet (20) secured to the body covering the opening, the bonnet having a tubular projection (24). A valve seat insert (34) having a valve seat (60) is positioned in the outlet, and a valve member (58) is movable toward and away from the valve seat to control flow through the valve. The valve seat insert (34) is releasably secured to the bonnet tubular projection (24). The insert is removable from the body with the bonnet (20) making it easy to replace.

    摘要： A cartridge packing assembly to seal a valve stem in a control valve assembly, the cartridge packing assembly comprising a seal assembly having a seal component to provide a fluid seal around the valve stem and at least a first anti-extrusion component to substantially prevent extrusion of the seal member about the valve stem. A loading assembly having a loading means to provide a predetermined packing stress upon the seal assembly and at least one spacer to couple the loading means to the seal assembly and a packing retainer adapted to be disposed in an outboard packing box of the control valve assembly, the packing retainer defining a packing bore receiving the seal assembly and the loading assembly wherein the packing retainer includes a predetermined length between a retainer shoulder and a loading means seating surface to control a loading assembly force that defines the predetermined packing stress in the control valve assembly.

    摘要： A valve with an integral bleed passage includes a valve body ( 12 ) including a threaded bore ( 14 ), a bonnet ( 18 ) having a first threaded portion ( 22 ) arranged to be securable to the bore of the valve body and having a second portion ( 24 ) disposed outside the valve body, and a cavity ( 26 ) defined between the val ve body and the first portion of the threaded bonnet. A bleed passage ( 28 ) is formed in the bonnet and includes an entrance aperture ( 30 ) formed in the first portion of the bonnet and in flow communication with the cavity, the passage including an exit aperture formed in the second portion of the bonnet, and a main portion providing flow communication between the entrance aperture and the exit aperture ( 31 ). The cavity and the entrance aperture are positioned to expose the passage to an interior portion of the valve prior to removal of the bonnet from engagement with the valve body.
