Abstract
The utility model relates to a gas sampling device which reduces the whole size, simplifies structure and improves gas tightness of sampling equipment. The gas sampling device comprises a gas inlet pipe and a barrel, wherein the gas inlet pipe is sleeved in the barrel. A gas inlet device is positioned at the combination position between the gas inlet pipe and the barrel, and the gas inlet device is matched with a gas hole II in the gas inlet pipe.
Description
Technical field
The utility model relates to a kind of gas sampling device.
Background technology
In the detection of packing container composition of gases within, the gas in container residual volume often seldom causes sampling inconvenient, requires higher to the impermeability of gas sampling device simultaneously.And the sampler complex structure of legacy equipment, impermeability is lower, inconvenient operation.
Summary of the invention
The purpose of this utility model for overcoming above problem, provides a kind of gas sampling device exactly, and it not only can dwindle cumulative volume, simplified structure, and improved the impermeability of sampling equipment.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of gas sampling device, it comprises draft tube and swivel nut, and draft tube is sleeved in the swivel nut, is provided with admission gear in both junctions, and the pore II in admission gear and the draft tube cooperates.
Described admission gear is admission piece, and admission piece is provided with pore I, and pore I cooperates with pore II, and the admission piece upper end is passed swivel nut and is connected with sample feeding pipe, and the bottom then is embedded in the draft tube.
Described admission piece and draft tube joint are provided with O-ring seal.
Described admission gear comprises the pore I in the swivel nut, and pore I lower end cooperates with pore II, and pore I upper end is provided with an inverted hydraucone with the swivel nut connectivity part, is provided with rubber plug between swivel nut and draft tube, with pore I and pore II isolating seal.
Described pore I cooperates with syringe, and syringe needle stretches among the pore II after passing pore I, rubber plug.
The beneficial effects of the utility model are: 1, good seal performance.2, change conveniently.3, simple to operate.
Description of drawings
Fig. 1 is the structural drawing of gas sampling device the first case study on implementation.
Fig. 2 is the structural drawing of gas sampling device the second case study on implementation.
Wherein, 1. swivel nut, 2. draft tube, 3. O-ring seal, 4. admission piece, 5. sample feeding pipe, 6. pore I, 7. pore II, 8. connecting thread, 9. rubber plug, 10. hydraucone, 11. syringes.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
Among Fig. 1, establish pore I6 in the admission piece 4, establish pore II7 in the draft tube 2, the corresponding connection with pore II7 of pore I6.Swivel nut 1 is connected by connecting thread 8 with draft tube 2.Admission piece 4 upper ends are passed swivel nut 1 and are received sample feeding pipe 5, and the lower end is embedded in the draft tube 2, and seal with O-ring seal 3.Sample air enters pore I 6 successively by sample feeding pipe 5, and pore II7 finishes gas sample.
Embodiment 2:
Among Fig. 2, swivel nut 1 is provided with hydraucone 10 and pore I 6, is provided with rubber plug 9 between swivel nut 1 and the draft tube 2.Syringe 11 passes pore I 6 and rubber plug 9 is inserted on the pore II7, and the sample air in the syringe 11 enters draft tube 2 by pore I6.
