YDZ-30 Self-pressurization Liquid Oxygen/Nitrogen/Argon Cylinder is mainly used in the transportation and storage of liquid medium (liquid nitrogen, liquid oxygen, and liquid argon), also can be used for cold source of other refrigeration device. This cylinder consists of inner tank, shell, meter and valve, etc. On the top, there is pressure meter, which is expediently to observe inner tank’s pressure. In order to enhance thesafety of using this cylinder, this cylinder is equipped with two safety valves

2. Application:
1) Liquid inlet: Liquid inlet from inlet/discharge valves. When perfuse liquid into liquid nitrogen cylinder, please firstly open air release valve, then connect metallic hose of transfusion to the inlet/discharge valve, open the inlet/discharge valve, then start to add liquid medium through the inlet/discharge valve, after finishing perfusion, close the inlet/discharge valve.
2) Storage:When you store liquid medium in this liquid nitrogen cylinder, please close the inlet/discharge valve and pressure charging valve, the air release valve must be open;
3) Transportation: When you transport liquid medium by this liquid nitrogen cylinder, all valve must be kept in the same status as its storage,
4) Transfusion:When you want to output liquid from this cylinder, please strictly abide by the following steps:
(1)close air release valve
(2)open pressure charging valve
(3)observe the pressure meter
(4)When the pressure rise to 0.05MPa (0.5kg/cm2), open discharge valve, then can have continuous transfusion.
3. Instruction:
When we delivery this cylinder to you, all valves are closed except safety valve.
