High-pressure helium and argon purifying device

The utility model discloses a high-pressure helium and argon purifying device, relating to the field of gas purifying devices and aiming at solving the problems that different gas sources can not be switched with each other and the impurity content of purified gas can not be ensured. The high-pressure helium and argon purifying device disclosed by the utility model comprises an argon purifier, an helium purifier, a plurality of valves and a plurality of pipelines, wherein the first pipeline provided with the argon purifier is provided with a plurality of stop valves; the second pipeline provided with the helium purifier is provided with a plurality of stop valves; a third pipeline connected in parallel with the first pipeline is arranged on the inlet of the first pipeline, a fourth pipeline connected in parallel with the second pipeline is arranged on the inlet of the second pipeline, and the third pipeline and the fourth pipeline are both provided with the stop valves. The high-pressure helium and argon purifying device disclosed by the utility model can realize the switching of different gas sources, reduce the disturbance of most of residual gas before normally working, ensure that the purified gas meet the requirement and be freely moved and locked.
