Description
Technical field
The utility model belongs to measuring for materials field, more particularly to a kind of sample cell for gas absorption instrument.
Background technology
Current people place sample more than carry out when gas absorption is tested using caliber U-tube equal everywhere, due to
Caliber with adsorption instrument Interface Matching, therefore need to cannot place larger sample.And in order to adsorption instrument Interface Matching, only increase U-shaped
The caliber in a part of region in pipe setting-out side simultaneously sets injection port at the position, then the heating of adsorption experiment is in due to the position
, there is poor air-tightness in area.
Utility model content
The purpose of this utility model is to provide a kind of sample cell for gas absorption instrument, i.e., one kind is carrying out gas absorption
Ensure that sample is contacted with experimental gas and ensures the device for placing sample of air-tightness during experiment, concrete technical scheme is as follows：
A kind of sample cell for gas absorption instrument, including a U-tube and a connecting tube, the U-tube is divided into be put
Sample side, bottom and connecting side, the connecting tube are connected by nut with U-tube setting-out side, the connecting tube and nut and U-tube
Between compressed sealing gasket and sleeve pipe.
Wherein, the interior caliber of U-tube setting-out side is more than bottom and the interior caliber of connecting side.
Connecting tube is divided into two sections by outer tube diameter, and thick outer tube diameter section and thin outer tube diameter section are followed successively by from lower to upper；Connecting tube is pressed
Interior caliber is divided into three sections, and caliber section in thick, interior caliber converging transition and thin interior caliber section are followed successively by from lower to upper.Connecting tube it is thick in
The interior caliber of caliber section is identical with the outer tube diameter of sleeve pipe, more than the outer tube diameter of U-tube setting-out side；In thick interior caliber section and interior caliber
The intersection of converging transition, interior caliber is identical with the interior caliber of U-tube setting-out side by the outer tube diameter identical mutation with sleeve pipe；Up
It is interior caliber converging transition, interior caliber is tapered to the outer tube diameter less than U-tube connecting side and no longer changes；It is up thin interior caliber
Section.The outer tube diameter of the thin outer tube diameter section of connecting tube is identical with the outer tube diameter of U-tube connecting side, so as to guarantee to insert adsorption instrument
Interface.
Connecting tube has screw thread on the outside of the one end being connected with U-tube, is constituted between nut and is threadedly coupled.
The material of connecting tube, sleeve pipe and nut is metal, and the material of U-tube is quartz glass, and gasket material is selected
Rubber.
The application of sample cell as described above：Sample is loaded into U-tube by setting-out side, using nut by connecting tube and U
Shape pipe links together, tightening nuts so that sleeve pipe compress sealing gasket, so as to ensure air-tightness；Connecting tube upper end, U-tube are connected
Connect side upper end to be connected with gas absorption instrument respectively, you can carry out related experiment.
In the utility model, air-tightness ensure that by sleeve pipe and sealing gasket；Simultaneously because connecting tube is located at the upper of U-tube
End, connection member can individually carry out cooling treatment away from heating zone during heating, reduce the temperature of junction, preferably protect
Air-tightness is demonstrate,proved.
The utility model U-tube both sides caliber is different, and setting-out side uses big caliber, so as to meet placement compared with large sample
Demand；Bottom and connecting side use small caliber, match corresponding gas absorption instrument, and reduce the volume of non-sample section.
The beneficial effects of the utility model are：Sample cell air-tightness is good, and can place large-sized sample.
Brief description of the drawings
Fig. 1 is sample cell described in the utility model longitudinal sectional drawing when in use；
Fig. 2 is the partial enlarged drawing of sample cell described in the utility model；
Wherein, 1- connecting tubes, 2- sealing gaskets, 3- sleeve pipes, 4- nuts, 5-U shape pipes.
Specific embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings, but does not therefore limit this
The protection domain of utility model.
Embodiment 1
A kind of sample cell for gas absorption instrument as depicted in figs. 1 and 2, including a U-tube 5 and a connecting tube
1,5 points of the U-tube is setting-out side, bottom and connecting side, and the connecting tube 1 is connected by nut 4 with the setting-out side of U-tube 5, institute
State and sealing gasket 2 and sleeve pipe 3 have been compressed between connecting tube 1 and nut 4 and U-tube 5.
Wherein, the interior caliber of the setting-out side of U-tube 5 is more than bottom and the interior caliber of connecting side.
Connecting tube 1 is divided into two sections by outer tube diameter, and thick outer tube diameter section and thin outer tube diameter section are followed successively by from lower to upper；Connecting tube 1
