    • A press-fit in situ retrofit assembly for a top entry valve and a method thereof are disclosed. The assembly includes an annular conduit (201) including a segment (202) of reduced outside diameter and a shoulder (203) on the exterior surface at the proximal end (204), and is configured to conform with an interior surface (205) of a valve seat (206) at the distal end (207). A valve body extension (208) with an interior annular region (301), and an inlet port (209) fluidically connected to the annular region (301). A gland packing push plate (211) is configured to allow the annular conduit (201) to pass through thereby forming an outlet port (212). And a thrust plate (403) is attached to the thrust screws (401). The thrust plate (403) allows the segment (202) of reduced outside diameter at the proximal end (204) of the annular conduit (201) to pass through, with the thrust plate (403) seating on the shoulder (203). The assembly and the method allow the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.
    • 公开了一种用于顶部进入阀的压配合现场改装组件及其方法。 该组件包括环形导管(201),该环形导管(201)包括外径减小的节段(202)和在近端(204)处的外表面上的肩部(203),并且构造成与 在远端(207)处的阀座(206)。 具有内部环形区域(301)的阀体延伸部(208)以及流体连接到环形区域(301)的入口端口(209)。 压盖填料推动板(211)构造成允许环形导管(201)穿过,由此形成出口端口(212)。 并且止推板(403)连接到止推螺钉(401)。 止推板(403)允许环形导管(201)的近端(204)处外径减小的节段(202)穿过,其中止推板(403)安置在肩部(203)上。 该组件和方法允许根据需要从冷箱中取出一部分流体用于下游处理或操作。
