Accompanying drawing explanation
Fig. 1 is the structural representation of the device of oxygen in the removal mixed gas in the utility model.
Embodiment
Below in conjunction with Fig. 1, describe a preferred embodiment of the present utility model in detail.
As shown in Figure 1, be the device of oxygen in removal mixed gas provided by the utility model, it comprises: degassed cylinder 1, and it is for hollow circuit cylinder body structure and both side ends arranges opening, and deoxidizer 2 is filled in the inside of this degassed cylinder 1; Seal assembly, is separately positioned on the both side ends opening part of described degassed cylinder 1; Gas conduit, is each passed through the inside that corresponding seal assembly stretches into degassed cylinder 1.
Described degassed cylinder 1 adopts stainless steel material to make.
The outer wall of the both side ends of described degassed cylinder 1 is provided with external thread.
Described seal assembly comprises: nut 31, and the external thread that the end outer wall of its internal thread and described degassed cylinder 1 is arranged matches, and tightens this nut 31 and makes it be fixedly mounted on the open-ended place of described degassed cylinder 1; Packing ring 32, it is arranged between described nut 31 and the end of degassed cylinder 1, plays sealing function.
Described packing ring 32 is O type rubber washer.
Described seal assembly also comprises metal spacer 33, and it is arranged between described packing ring 32 and the end of degassed cylinder 1; This metal spacer 33 plays buffer action, prevents the deoxidizer 2 in fine particle shape from exporting in follow-up detecting instrument together along with mixed gas, prevents deoxidizer 2 from spilling in the filling process simultaneously.
Described metal spacer 33, in reticulate texture, while isolation deoxidizer 2, makes mixed gas to flow out smoothly.
Described nut 31 is provided with through hole.
Described gas conduit comprises: draft tube 41, and gas, through the through hole be arranged on the nut 31 at degassed cylinder 1 wherein open-ended place, side, is inputted degassed cylinder 1 by it; Escape pipe 42, it is through the through hole be arranged on the nut 31 of degassed cylinder 1 end side opening part, is exported by the gas in degassed cylinder 1.
The internal diameter of the through hole on described draft tube 41 and the external diameter of escape pipe 42 and described nut 31 matches.
The device of oxygen in removal mixed gas provided by the utility model, send in degassed cylinder 1 by needing the mixed gas comprising oxygen argon component carrying out sample detection by draft tube 41, deoxidizer 2 in degassed cylinder 1 is by the oxygen absorption in mixed gas, therefore, the mixed gas of finally deriving from escape pipe 42 is exactly the oxygen components eliminated wherein, and remains the component that other all needs carry out detecting.Now, then mixed gas is inputted in sampling valve, can normally detect.That is, the utility model is exactly the oxygen for removing in the oxygen argon gas component that cannot be separated in chromatographic column, and retains the gas composition that other needs detect.
