YDZ-15 Self-pressurization Liquid Oxygen/Nitrogen/Argon Cylinderis mainly used in the transportation and storage of liquid medium(liquid nitrogen, liquid oxygen, and liquid argon), also can beused for cold source of other refrigeration device. This cylinderconsists of inner tank, shell, meter and valve, etc. On the top,there is pressure meter, which is expediently to observe innertank’s pressure. In order to enhance thesafety of using thiscylinder, this cylinder is equipped with two safety valves

2.Application:    
1) Liquidinlet:  Liquid inlet from inlet/dischargevalves. When perfuse liquid into liquid nitrogen cylinder, pleasefirstly open air release valve, then connect metallic hose oftransfusion to the inlet/discharge valve, open the inlet/dischargevalve, then start to add liquid medium through the inlet/dischargevalve, after finishing perfusion, close the inlet/dischargevalve.       
2)Storage:When you store liquid medium in this liquidnitrogen cylinder, please close the inlet/discharge valve andpressure charging valve, the air release valve must beopen;    
3)Transportation: When you transport liquid medium bythis liquid nitrogen cylinder, all valve must be kept in the samestatus as its storage,   
4)Transfusion:When you want to output liquid fromthis 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 dischargevalve, then can have continuoustransfusion.    
3.Instruction:    
When we delivery this cylinder to you, all valves are closed exceptsafety valve.
