Embodiment
Embodiment 1
As shown in Figure 1, air mix facilities of the present invention comprises water sample case 1, zero sample case 2, little gauge line 3, exhausted bath box 4, liquid testing device 5, metering pond 6, suction pump 7, the water sample case is used to deposit detected sample liquid, zero sample case is used to deposit dilution, little gauge line 3 is little metering pipeline, the upper end connects first passage 9, the lower end connects second channel 10, one end of first passage 9 is provided with first valve 11, the head piece of going into of first valve 11 is connected with first passage 9, going out family status is connected with exhausted bath box 4, first passage 9 other ends set gradually liquid testing device 5, metering pond 6, suction pump 7, one end of second channel 10 is provided with second valve 12, the head piece of going into that the other end is provided with the 3rd valve 13, the second valves 12 is connected with water sample case 1, goes out head piece and is connected with the left side port of second channel 10, the head piece of going into of the 3rd valve 13 is connected with zero sample case 2, goes out head piece and is connected with the right side port of second channel 10.
Be the capacity of water sample on the metering pond that can accurately and timely read and/or zero sample, metering also is provided with containing mark on the pond; Safe and reliable for ease of what operate and install, valve adopts solenoid valve.
In addition, the present invention also comprises a control device 19, is used for the work of whole by-pass valve control, suction pump.
Principle of work:
Before the startup, first valve 11, second valve 12, the 3rd valve 13 all are in closed condition.
Open second valve 12, open suction pump 7, under the suction pump suction, the water sample in the water sample bucket 1 by the road 21, after being detected by detector of liquid 5, the suction pump stall.This moment, liquid resided in the pipeline, as shown in Figure 3.
Close second valve 12, open first valve 11, suction pump 7 counter-rotatings (blowing in pipeline) are driven into waste liquid barrel 4 with the water sample that resides in the first passage 9, suction pump 7 stalls.The residue water sample resides in little gauge line 3 and the second channel 10, as shown in Figure 4.
Close first valve 11, open the 3rd valve 13, suction pump 7 is just being changeed, and at this moment, the water sample in little gauge line 3 enters metering pond 6 by the road, thereupon, zero sample in the zero sample bucket also enters metering pond 6 by the road, obtains the water sample dilution at last, sends into analytic system 22 by suction pump 7 again, analyze, as shown in Figure 5.
Above-mentioned each link operation is finished automatically by control device 19.
Adopt the computing formula of dilution ratio of the present invention to be: to suppose that it is that (suction pump has the ability of quantitative extraction liquid to the A milliliter that volume is extracted in suction pump, extracting volume can obtain by observing metering tankage scale), the volume of little gauge line 3 is the B milliliter, and so, dilution ratio is: (A-B)/and B.In view of the volume B of little gauge line 3 can do very little, it is very big that dilution ratio also just can be done.Traditional relatively air mix facilities, this device does not need expensive flow measurement device, as long as just can accurately calculate dilution ratio by the volume of gauge line 3 and the volume in metering pond, does not need very big diluting tank yet, by changing little gauge line 3 volumes, it is very little that the metering pond also can be done.
As shown in Figure 2, the present invention further optimization scheme, also be provided with a pedestal 14, be wholely set little gauge line 3 by pedestal 14, first passage 9, second channel 10, third channel 15, four-way 16, five-way road 17, described first valve 11, second valve 12, going into of the 3rd valve 13, go out head piece and first passage 9, second channel 10, third channel 15, four-way 16, one side ports in five-way road 17 is corresponding to connect exhausted bath box 4, water sample case 1, zero sample case 2 and the liquid testing device 5 that sets gradually, metering pond 6, suction pump 7 is by flexible pipe 18 and third channel 15, four-way 16, the opposite side port in five-way road 17 is corresponding to be connected.
The work of present embodiment is original identical with embodiment 1, the improvement advantage of embodiment 1 is relatively: because general water sample has very strong corrosivity, can can produce harmful effect to device, each passage and pedestal are wholely set, can increase the service life, each valve can be fixed on the pedestal 14 in addition, is convenient to Unit Installation and maintenance, be connected with each passage, liquid case by flexible pipe, equally also make things convenient for the installation and the replacing of each accessory of device.
