摘　　要：提出了低温液体贮罐在真空规管损坏的情况下的两种解决方案,并对在V6真空隔离阀法兰下方加装带真空规管真空阀的方案进行现场实施,最后测量真空度在相关规程规定的范围之内,结果表明:在真空隔离阀法兰下方加装带真空规管真空阀的方案可行,解决了在用低温液体贮罐由于真空规管损坏情况下更换规管需要的停产放空、焊接和抽真空等问题。Cryogenic liquid storage tank under vacuum gauge damaged two kinds of solutions, and with the installation of the gauge at the bottom of the isolation valve V6 vacuum tube vacuum valve flange-site program implementation, measuring the degree of vacuum in the range of the relevant provisions of the regulations, the results show that under the vacuum isola- tion valve flange installation with vacuum gauge vacuum valve is feasible to solve it with cryogenic liquid storage tank damage due under regulatory vacuum replace regulatory needs discontinued venting, vacuum welding and other issues.
