Embodiment
Fig. 1-2 and following description describe Alternate embodiments of the present utility model and how to implement to instruct those skilled in the art and to reproduce the utility model.In order to instruct technical solutions of the utility model, simplifying or having eliminated some conventional aspects.Those skilled in the art should understand that the modification that is derived from these embodiments or replace will in scope of the present utility model.Those skilled in the art should understand that following characteristics can combine to form multiple modification of the present utility model in every way.Thus, the utility model is not limited to following Alternate embodiments, and only by claim and their equivalents.
Embodiment 1:
Fig. 1 schematically illustrates the structure diagram of the sampling apparatus of the utility model embodiment, and be applied in the formula sampling in place of flue gas monitoring, as shown in Figure 1, described sampling apparatus comprises:
Sampling pipe, filter chamber 11, sampling pipe is arranged on the side of filter chamber, arranges filtrator 21 in described filter chamber; Sampling pipe and filtrator, filter chamber are the state of the art, do not repeat them here;
Body 31, described body is fixed on the side of described filter chamber;
First passage 32, described first passage runs through described body, and two ends are communicated with filter interior and the external world respectively, and source purge gas is by first passage described in pipeline communication;
Second channel 33, described second channel is arranged in described body, has and is communicated with extraneous internal diameter major part 331 and the internal diameter smaller portions 332 being communicated with described first passage; Described internal diameter major part has ring-shaped step 333, and the end of described internal diameter smaller portions has open circles taper; Described source purge gas is by second channel described in pipeline communication;
Fig. 2 schematically illustrates the cut-open view of the separator of the utility model embodiment, and as shown in Figure 2, separator 41 is overall cylindrical, and bus is zigzag; Described separator is fixed on described ring-shaped step, thus second channel is isolated into two spaces; The area at separator top is greater than the sectional area of internal diameter smaller portions; Separator adopts stainless steel to make, thus makes separator that elastic deformation (being similar to spring) can occur, and achieves the function of elastic component;
Plug 42, one end of described plug is turbination, mates with the end of described internal diameter smaller portions, thus realizes sealing.The maximum outside diameter of plug is greater than the internal diameter of described internal diameter smaller portions, is between described separator and internal diameter smaller portions, and connects described elastic component;
