고압가스 입출구(121a)에 나사홀(121b)이 형성된 목부(121)를 갖도록 금속 라이너로 제작된 용기본체(12)와, 용기본체(12)의 외면에 목부(121)의 일부를 노출시킨 상태에서 탄소유리섬유 복합재로 접합시킨 용기본체 외피층(14)과 다층단열층(15)으로 이루어지되,
용기본체(12)의 목부(121)에서 외부로 노출되는 부분을 감싸서 급격한 열손실을 방지하기 위해 GFRP(유리섬유복합재)로 제작된 목부단열캡(16)이 목부(121)에 나사 결합되어 있고,
상기 용기본체(12)의 목부(121) 내면에는 저온에서도 금속탄성력을 발휘하여 극저온 고압가스 용기(10)에 접속되는 고압유출입튜브(20)와의 실링기능을 유지하는 에너자이즈드링(18)이 설치되고, 고압유출입튜브(20)의 외면에 목부(121)를 벗어난 구간으로 유리섬유 50중량부 이상이 포함된 유리섬유복합재로 피복된 복합단열층(201)이 형성되어 있는 것을 특징으로 하는 목부에 단열구조를 갖는 극저온 고압가스 용기. - 제 1항에 있어서,
상기 목부단열캡(16)은 목부(121)의 노출된 외주면을 감싸는 원통형의 목부견착부(161), 목부견착부(161)에서 절곡 연장되어 목부(121)의 선단에 밀착되는 목부링판(162), 목부링판(162)에서 고압가스 입출구(121a)를 향해 절곡되어 외면에 수나사부를 형성하는 목부체결부(163)를 이루는 것을 특징으로 하는 목부에 단열구조를 갖는 극저온 고압가스 용기. - 삭제
- 제 1항에 있어서,
상기 다층단열층(15)은 슈퍼 단열 매트(Super insulation mat), 에어로젤(Aerogel), 진공단열패널(Vaccum insulation pannel) 중 어느 하나로 이루어진 것을 특징으로 하는 목부에 단열구조를 갖는 극저온 고압가스 용기. - 삭제
