Self-pressurized Cryogenic Vessel Trouble Shooting

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2017-09-05
         Self-pressurized Cryogenic Vessel Trouble Shooting
         (1) If there being any leakage phenomena in the joints such as valves and so on, it may caused because of the non-tight compression nut seal to the valve or the damaged gasket; it shall be screwed tightly by using the spanner or the gasket shall be replaced.
         (2) The ice blocking phenomenon may be occurred generally in the pressurization coil and sometimes may be occurred in the liquid discharging pipe because the moisture in the entering air may not be discharged fully and be condensed into ice under the low temperature so as to block the pipe; the corresponding solution may be to use the nitrogen cylinder (or the compressed air cylinder) at first to fill the vessel with nitrogen (or compressed air) through the relief valve; while the vessel internal pressure is increased to 0.05-0.09MPa, the liquid medium in the vessel shall be emptied (if the liquid supply pipeline is jammed, the liquid shall be discharged from the front end of the pressure increasing valve; If the pressure increasing pipeline is jammed, the liquid shall be discharged from the liquid supply pipe); then the hot nitrogen or the dry heated air may be used to purge the ice-blocking pipeline to blow out ice; then all valves shall be switched off.
         Features:
         *YDZ series are equipped with double safety auto-control valves and double protective measure, which are more safe to use.
         *This kind of products have the feature of increasing pressure and draining the liquid continuously, which helps to effectively fill the liquid .
         *The movable wheels with high carrying capacitymake it easily move.
         *The special ultra-low temperature cut-off valves are easier to operate.They are durable and elegant.
