Description
Technical field
The utility model is related to a kind of portable gas sampler.
Background technology
Traditional gas sampling system is mostly by air intake duct 8, air pump 9, appendix 10, stop valve 11, gas-storing bag 12 etc.
Multiple independent part compositions, structural representation such as Fig. 1.Gas sampling field assembly and disassembly is all troublesome, and air pump
Also need to be equipped with corresponding external power supply 13, operate extremely inconvenience.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of portable gas sampler, simple structure, side
Convenient to operate, sampling precision is high, low cost.
To realize above-mentioned technical purpose, the scheme that the utility model is provided is：A kind of portable gas sampler, including phase
Intercommunicated vacuum noz(zle) and the sleeve pipe for gas storage, the vacuum noz(zle) are provided with valve, and the side wall of described sleeve pipe is telescopic joint, sleeve pipe
First end face connection vacuum noz(zle), second end face for outer face be provided with handle handle piston, the piston be in sleeve pipe in and its is big
Small cannula cavity size when being reduced to minimum with telescopic joint is consistent, and outer face and the pipe sleeve of piston are conjoined structure, telescopic joint
After stretching, the cavity as air storing cavity surrounded by sleeve pipe, sleeve first end face, piston inner face.
And, the flexible fold uniformity of the telescopic joint.
And, the piston is made with sleeve pipe using vinyon.
And, the valve is plug valve or check valve.
The beneficial effects of the utility model are：
1st, simple structure, complex environment that is easy to operate, being adapted to sampling location；
2nd, low cost, can single use, it is also possible to reuse, easy to clean；
3rd, after sleeve pipe purse up, the gap very little between piston, it is ensured that the residual quantity of gas is minimum, is adopted so as to improve
Sample precision；
4th, sleeve pipe is that stretching launches paragraph by paragraph, and every section of volume is consistent, and the tolerance of collection is controllable, measurable.
Brief description of the drawings
Fig. 1 is traditional gas sampling system structural representation.
Fig. 2 is structural representation when the utility model shrinks.
Fig. 3 is structural representation when the utility model is stretched.
Wherein, 1, vacuum noz(zle), 2, valve, 3, telescopic joint, 4, first end face, 5, piston, 6, handle handle, 7, air storing cavity, 8,
Air intake duct, 9, plug valve, 10, air pump, 11, pipe joint, 12, gas-storing bag, 13, power supply.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides a kind of portable gas sampler, as shown in Figures 2 and 3, including interconnected vacuum noz(zle) 1
With the sleeve pipe for gas storage, the vacuum noz(zle) 1 is provided with valve 2, and the side wall of described sleeve pipe is telescopic joint 3, the first end face 4 of sleeve pipe
Connection vacuum noz(zle) 1, second end face for outer face be provided with handle 6 piston 5, the piston 5 be in sleeve pipe in and its size with stretch
Cannula cavity size when casing coupling 3 is reduced to minimum is consistent, and outer face and the pipe sleeve of piston 5 are conjoined structures, and telescopic joint 3 is stretched
Afterwards, the cavity as air storing cavity 7 for being surrounded by sleeve pipe, sleeve first end face 4, the inner face of piston 5.
Further, the flexible fold uniformity of the telescopic joint 3, convenient metering.
Further, the piston 5 and sleeve pipe are made using vinyon, low cost, can single use, also may be used
It is easy to clean to reuse.
Further, the valve 2 is plug valve or check valve, prevents from managing interior gas effusion.
Principle of the present utility model is：Sleeve pipe is changed to telescoping tube, using the stretching of sleeve pipe, and parital vacuum is formed.
Here, piston 5 and sleeve pipe disjunctor, make of vinyon, similar with traditional pond drainage pipe structure.When with pulling work
When the handle of plug 5 is 6, sleeve pipe is just stretched paragraph by paragraph, completes gas sampling；When with the handle of hand pressure piston 56, sleeve pipe just by
Section is closed up, sample in discharge pipe, or air is prepared for lower sub-sampling in row's air storing cavity 7.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvement or deformation can also be made, these improve or
Deformation also should be regarded as protection domain of the present utility model.
