2 儲罐的操作Tank operation
【產品詳情圖片】
儲罐的操作分為充液、貯存、增壓、排液等過程，每個過程必須做到：V6三通截止閥（連接安全閥）和V8液位計組合閥始終處于全開狀態(tài)。罐內壓力不應高于2.16Mpa，壓力不應低于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.

液體的排放 liquid discharge
【產品詳情圖片】
2.4.1液體二氧化碳的正常排放是在儲罐增壓后，開啟V2排液閥，V3回氣閥，液體二氧化碳便流入汽化器汽化，供使用點使用。
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為滿足排液過程的穩(wěn)定壓力，應按“儲罐的增壓”操作方法進行增壓。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".
