液体的储存 liquid storage
液体二氧化碳的储存属于带压（压力不低于0.8Mpa）储存。储存期间除压力表、液位计、安全阀应投入使用外，其他阀门应处于关闭状态。当储罐压力超过2.1Mpa时，开启V7排气阀降压。但应注意：内罐的压力不得降至低于0.8Mpa，否则将引起液体二氧化碳转变为干冰。
Liquid carbon dioxide storage with pressure (pressure not less than 0.8Mpa) storage. During the storage, the pressure gauge,level gauge, safety valve should be put into use, the other valves should be closed. When the tank pressure exceeds 2.1Mpa, open the V7 exhaust valve buck. However, it should be noted that the pressure inside the tank must not drop below 0.8Mpa, otherwise liquid carbon dioxide will be converted to dry ice.
