Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, a kind of etchant gas sampling apparatus, comprising: a sampling bottle 100, lays respectively at the first T-valve 200 and second T-valve 300 of sampling bottle 100 both sides;
Wherein the first port 210 of the first tee ball valve 200 is by the inlet end of the first pipeline 410 access rapid-acting coupling 400, the second port 220 access second pipes 600, the entrance point 110 of the 3rd port 230 access sampling bottles 100;
Wherein the first port 310 of the second tee ball valve 300 is equipped with the absorption cell of absorption liquid, the endpiece of the second port access 320 access second pipes 600, the endpiece 120 of the 3rd port 330 access sampling bottles 110 by the 3rd pipeline 510 accesses;
In actual production technique, the first port 210 of the first tee ball valve 200 and the 3rd pipeline 510 of the second tee ball valve 300 are the common port of tee ball valve separately.
In addition, between the 3rd port 230 of the inlet end 110 of sampling bottle 100 and described the first tee ball valve, the first valve 130 is set as required, between the 6th port 330 of the endpiece 120 of described sampling bottle 100 and described the second tee ball valve, the second valve 140 is set; This first valve 130 and the second valve 140 are for controlling the break-make of sampling bottle inside.
While gathering corrosive gas, the first step purges system with nitrogen, and second step purges system with etchant gas, and the 3rd step gathers corrosive gas, and the 4th step purges pipeline with nitrogen.
Concrete operations are as follows:
The first step purges system with nitrogen: first rapid-acting coupling 400 is connected to nitrogen pipeline, again by regulating the first tee ball valve 200 that the first pipeline 410 is connected with sampling bottle 100, open sampling bottle valve 130 and 140, regulate the second tee ball valve 300 that the 3rd pipeline 510 is connected with sampling bottle 100, open nitrogen system is purged;
