Latest Patents

Jianwei Li holds a patent for a "Press fit valve adaptation for top entry valve in cryogenic service." This invention involves a press-fit in situ retrofit assembly designed for a top entry valve. The assembly includes an annular conduit with a segment of reduced outside diameter and a shoulder on the exterior surface at the proximal end. It is configured to conform with the interior surface of a valve seat at the distal end. The design also features a valve body extension with an interior annular region and an inlet port fluidically connected to the annular region. Additionally, a gland packing push plate allows the annular conduit to pass through, forming an outlet port. A thrust plate is attached to the thrust screws, enabling the segment of reduced outside diameter at the proximal end of the annular conduit to pass through while seating on the shoulder. This assembly and method facilitate the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.
