Document Type and Number:
WIPO Patent Application WO/2020/091037
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an extremely low-temperature globe valve which, despite having a simple structure, is capable of maintaining high sealing property and safety with respect to extremely low-temperature fluids even after a large number of openings and closings, and which is easy to maintain. The extremely low-temperature globe valve comprises a body through which an axial shaft cylinder of long-neck structure extends. A resin valve body having a conical surface tapering with decreasing diameter is attached to the lower end of an elongate stem in such a way that the resin valve body is 3-dimensionally operable relative to the stem even under an extremely low-temperature condition.
