detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.

As shown in Fig. 1, the utility model embodiment comprises gas inlet 1, sampler 3, air extraction pipeline 5, tee 2, base 6 and sample collecting bottle 4; Gas inlet 4 passes and tee 2 and air extraction pipeline 5 The remaining end of the tee 2 is provided with a gas circulation pipe 3-3.

The sampler 3 includes a sliding sampling bottle 3-1 and a condenser 3-2, the sliding sampling bottle 3-1 is sleeved in the condenser 3-2, and the sliding sampling bottle can slide up and down along the inner wall of the condenser; the gas flow pipe 3-3 Placed in the sliding sampling bottle 3-1; overflow pipe 3-4 is installed on the side wall of the sliding sampling bottle 3-1;

The base 6 is arranged under the sliding sampling bottle 3-1, and the base 6 is fixed with a spring 3-8 and a sample collection bottle 4; the upper part of the sample collection bottle 4 is equipped with a pipe 3-7. When the sliding sampling bottle 3-1 sinks, the outlet 3-5 of the overflow pipe 3-4 corresponds to the inlet 3-6 of the pipeline 3-7 to discharge the condensed liquid in the sliding sampling bottle 3-1 to the collection bottle 4. The sliding sampling bottle 3-1 is connected with the base through the lower vertical spring 3-8.

In order to ensure the use effect, the overflow pipe 3-4 and the pipe 3-7 are all L-shaped hollow pipes;

The lower end of the gas flow pipe 3-3 is placed on the inner bottom of the sliding sampling bottle 3-1, and the overflow pipe 3-4 is placed on the lower bottom side of the sliding sampling bottle 3-1;

Described condenser 3-2 is made of circular shell and the condensing tube that shell is installed, covers the outside of sliding sampling bottle 3-1.

The working condition of the present utility model is that the gas inlet 1 flows into the bottom end of the sliding sampling bottle 3-1 through the three-way valve 2, and becomes liquid under the cooling effect of the condenser 3-2, and the liquid is left in the bottom end of the sliding sampling bottle 3-1 ; When the liquid sample in the sampling bottle is enriched to the upper port of the L-shaped overflow pipe 3-4, the sample flows into the L-shaped overflow pipe 3-4 to retain, and due to the change of gravity, the spring connected to the bottom of the sliding sampling bottle 3-1 3-2 is compressed and sinks, when the L-shaped overflow pipe outlet 3-5 at the bottom of the side wall of the sliding sampling bottle 3-1 is connected to the inlet 3-6 at the bottom of the inner wall of the condenser 3-2, the sliding sampling bottle 3 The liquid sample inside -1 flows into the sample collection bottle 4 along the pipeline 3-7. When the sample flows out, the gravity decreases, the spring 3-2 resumes elastic deformation, the position of the sliding sampling bottle 3-1 rises, the outlet 3-5 of the L-shaped overflow pipe is staggered from the inlet 3-6, the sample no longer flows out, and the sample is realized. Automatic collection, no need to turn off the vacuum pump and manual sampling, thus saving sampling time, improving work efficiency and ensuring the continuity and accuracy of the experiment, which has good economic and social benefits.
