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.

2 储罐的操作Tank operation
【产品详情图片】
储罐的操作分为充液、贮存、增压、排液等过程，每个过程必须做到：V6三通截止阀（连接安全阀）和V8液位计组合阀始终处于全开状态。罐内压力不应高于2.16Mpa，压力不应低于0.8Mpa .
The operation of the tank is divided into filling, storage, pressurization, drainage and other processes, each process must be: V6 three-way valve (connecting safety valve) and V8 level gauge combination valve is always in the fully open state. Tank maximum pressure should not exceed 2.16Mpa, the minimum pressure should not be less than 0.8Mpa.

液体的排放 liquid discharge
【产品详情图片】
2.4.1液体二氧化碳的正常排放是在储罐增压后，开启V2排液阀，V3回气阀，液体二氧化碳便流入汽化器汽化，供使用点使用。
The normal discharge of liquid carbon dioxide is after pressurization of the tank, open the V2 drain valve, V3 return valve, the liquid carbon dioxide will flow into the vaporizer vaporization for use point.
2.4.2为满足排液过程的稳定压力，应按“储罐的增压”操作方法进行增压。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".
