The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Fig. 1 is the quantitative mixed gas compounding apparatus structure of absolute pressure value of the present utility model schematic diagram.
As shown in Figure 1, the utility model provides a kind of absolute pressure value quantitative mixed gas compounding device, comprise that some unstripped gas pipeline 1, a road spirit pipeline 2, a road system vacuum pipeline 3, pressure adjusting cylinders 5, absolute pressure sensor 4, a quantity tube 8 and a mist collect cylinder 12, after each pipeline parallel connection, be connected with one end of quantity tube 8, the other end exit of quantity tube 8 connects mist and collects cylinder 12, and pressure adjusting cylinders 5 and absolute pressure sensor 4 are arranged between pipeline and quantity tube 8.
Device arranges some magnetic valves.Magnetic valve has five, is respectively magnetic valve 1, magnetic valve 27, magnetic valve 39, magnetic valve 4 10, magnetic valve 5 11; Magnetic valve 1 is positioned at pressure adjusting cylinders 5 ports, magnetic valve 27 is positioned at the port of quantity tube 8 and pipeline one end, and magnetic valve 39, magnetic valve 4 10, magnetic valve 5 11 lay respectively at quantity tube 8 one end, exit and mist is collected on three branch roads of cylinder 12 junctions.
The utility model course of work is as follows:
1) system vacuum extracts: close all unstripped gas valves, open magnetic valve 1, magnetic valve 27, magnetic valve 39, magnetic valve 5 11, by vacuum drawn valve, system is vacuumized, then close all valves;
2) calculation in quantity pipe pressure: the pressure of calculating the interior needed raw material gas of quantity tube 8 according to the outlet pressure of the concentration of unstripped gas, unstripped gas, the concentration of required each component of mixed gas compounding and the stereometer of quantity tube;
3) unstripped gas quantitatively and shift: the outlet pressure that unstripped gas is set is fixed value P
0, by calculating the pressure of this gaseous mixture quantity tube needed raw material gas of preparation, be P
1, work as P
1> P
0time, open unstripped gas valve, magnetic valve 27, unstripped gas is filled with quantity tube, now P
1=P
0, shut electromagnetic valve 27, opens magnetic valve 1, by unstripped gas charged pressure adjusting cylinders 5, closes unstripped gas valve, again opens magnetic valve 27, by 5 pairs of quantity tubes of pressure adjusting cylinders 8, carries out pressure compensation, and the pressure demonstration on absolute pressure sensor 4 reaches P
1time, shut electromagnetic valve 1, magnetic valve 27, open magnetic valve 39, magnetic valve 5 11, the gas in quantity tube 8 is transferred to mist and collects cylinder 12; Work as P
1> P
0time, open unstripped gas valve, magnetic valve 27, unstripped gas is filled with quantity tube 8, now P
1=P
0, close unstripped gas valve, open magnetic valve 1, by pressure adjusting cylinders 5, regulate, the pressure demonstration on absolute pressure sensor 4 reaches P
1time, shut electromagnetic valve 1, magnetic valve 27, open magnetic valve 39, magnetic valve 5 11, the gas in quantity tube 8 is transferred to mist and collects cylinder 12, completes the collection of unstripped gas simultaneously;
