Go out path, the filter layer to connect to form the connection sample tube space filled below barred body and described with the jackscrew
Fill the gas passage of the sample cell exterior space above barred body.
The utility model embodiment also provides a kind of high temperature and high pressure gas adsorption instrument, including：Sample cell and it is located at the sample
Filler rod in pipe, the filler rod uses filler rod described in the utility model.
As seen from the above technical solution provided by the invention, filler rod provided in an embodiment of the present invention, by filling out
Fill on the turnover path of the gas in barred body and filter layer is set, and the sample cell to be formed below the connection filling barred body is set
The gas passage of sample cell exterior space above space and the filling barred body so that the filler rod has filtering function, from
And can thoroughly prevent pollution of the sample to instrument interior structure on the premise of gas flux is not influenceed, and the filler rod can be with
Repeat practical, the use cost in reduction test process, and it is possible to effectively reduce the dead volume in test process, is improved and surveyed
Try precision.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, required in being described below to embodiment
The accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present utility model
Example, on the premise of not paying creative work, can also be according to these accompanying drawings for one of ordinary skill in the art

The structural representation for the filler rod with filtering function that Fig. 1 provides for the utility model embodiment.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belongs to protection domain of the present utility model.
The utility model embodiment provides a kind of filler rod with filtering function of high temperature and high pressure gas adsorption instrument, and it is special
Levy and be, including：
Fill barred body, filter layer, jackscrew and sealing ring；Wherein,
Pass in and out and be provided with path, the gas turnover path of the filling barred body provided with gas in the filling barred body upper end
Be provided with the jackscrew filter layer being fixed in the gas turnover path of the filling barred body above filtering layer, the filter layer；
Sealing ring is arranged with outside the upper end of the filling barred body, is sealed by the sealing ring between sample inside pipe wall
Space；
Space is provided between the filling barred body bottom outer wall and the sample inside pipe wall, the space is entered with the gas
Go out path, the filter layer to connect to form the connection sample tube space filled below barred body and described with the jackscrew
