Description

초저온용 밸브Cryogenic Valve

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 본 발명의 구조 단면도.1 is a structural cross-sectional view of the present invention.

제 2 도의 (가)(나)(다)는 제 1도중 후렉시블 디스크의 구조설명도.2A and 2B are structural explanatory diagrams of the flexible disk in FIG.

제 4 도는 초저온 밸브 소재에서 충격특성이 델타-페라이트 함량 변화에 따라 달라지는 양상을 보여주는 그래프.4 is a graph showing how the impact characteristics in the cryogenic valve material depends on the delta-ferrite content change.
