Fig. 1 is the structural representation of the sampling detecting device of bleeding of the present utility model.
Embodiment
As shown in Figure 1, the sampling detecting device of bleeding of the present utility model comprises bleed sampling system and gas detection part, and the gas detection part is made of the gas sensor 25 with air inlet/outlet.
The sampling system of bleeding comprise first and second the group bleed-off passage 110,111 and with corresponding respectively first and second aspiration pump 112,113 that communicates of every group of bleed-off passage, every group of bleed-off passage includes the many exhaust tubes that have air inlet sampling head 21, each exhaust tube on the same group crosses by two three-way electromagnetic valves 22 and snorkel and is communicated to the air intake opening of corresponding aspiration pump, each exhaust tube of first group of bleed-off passage 110 is the 1st, 3,5,7,9,11 exhaust tubes, and each exhaust tube of second group of bleed-off passage 111 is the 2nd, 4,6,8,10,12 exhaust tubes.
The outlet side of first aspiration pump 112 is communicated with downtake pipe 14 and first respectively by threeway and treats stopple coupon 15, the outlet side of second aspiration pump 113 is communicated with second exhaust pipe 16 and second respectively by threeway and treats stopple coupon 17, is respectively equipped with two three-way electromagnetic valves 24,28 that are used to control the exhausr port break-make on first and second gas outlet 14,16.First and second treats that stopple coupon 15,17 communicates with two air intake openings of two-position three way magnetic valve 26 respectively, and single gas outlet of two-position three way magnetic valve 26 communicates with the air intake opening of gas sensor 25 by total stopple coupon 29.
Concrete workflow of the present utility model is as follows: two three-way electromagnetic valves of inlet end of opening the 2nd exhaust tube of the 1st exhaust tube of first group of bleed-off passage 110 and second group of bleed-off passage 111 simultaneously, two-way gas enters first respectively by two three-way electromagnetic valves separately, second aspiration pump 112,113, two three-way electromagnetic valves 24 that system controls on the downtake pipe 14 of first group of bleed-off passage 110 are closed, two three-way electromagnetic valves 28 on the second exhaust pipe 16 of second group of bleed-off passage 111 are opened, and two-position three way magnetic valve 26 carries out gating control, first treats that the stopple coupon 15 and the gas outlet of two-position three way magnetic valve 26 are switched on, second treats that stopple coupon 17 and being communicated with of two-position three way magnetic valve 26 are turned off, the 1st exhaust tube of such first group of bleed-off passage 110 just enters gas sensor 25 by two-position three way magnetic valve 26, and the gas of second group of bleed-off passage 111 just directly passes through two three-way electromagnetic valves, 28 outflows of the outlet of second exhaust pipe 16, also flows into simultaneously and treats that stopple coupon 17 enters state to be measured.
After the gas detection of the 1st exhaust tube of first group of bleed-off passage 110 finishes, two three-way electromagnetic valves 24 of downtake pipe 14 outlets of first group of bleed-off passage 10 are opened, the gas of the 1st bleed-off passage is discharged from, two three-way electromagnetic valves 28 of second exhaust pipe 16 outlets of second group of bleed-off passage 111 are closed, and two-position three way magnetic valve 26 carries out gating control, first treats that stopple coupon 15 and being communicated with of two-position three way magnetic valve 26 are turned off, second treats that the stopple coupon 17 and the gas outlet of two-position three way magnetic valve 26 are switched on, and the gas of the 2nd exhaust tube of second group of bleed-off passage 111 enters gas sensor 25 by two-position three way magnetic valve 26 after treating stopple coupon 17.Meanwhile gas access two three-way electromagnetic valves of the 3rd exhaust tube of first group of bleed-off passage 110 are opened, this channel gas enters the measurement state of preparing, after the gas detection for the treatment of the 2nd exhaust tube of second group of bleed-off passage 111 finishes, two three-way electromagnetic valves 28 of the second exhaust pipe 16 of second group of bleed-off passage 111 are opened, and two three-way electromagnetic valves 24 of the second exhaust pipe 14 of first group of bleed-off passage 110 are closed, and the gas of the 3rd exhaust tube of such first group of bleed-off passage 110 just enters gas sensor 25 by two-position three way magnetic valve 26.Gas in two groups of bleed-off passages is so cycle alternation sampling of bleeding like this.
Bleed-off passage in the foregoing description is two groups, and supporting two-position three way magnetic valve carries out two groups of gating operations for the treatment of stopple coupon that bleed-off passage connected.The how logical operation valve group that can certainly constitute with the many valves of how logical operation valve or multitube road of two-position three way magnetic valve other kinds commonly used unexpectedly, commercially available.And those of ordinary skill in the art, be not difficult to determine to have the technical scheme of the exhaust tube more than three groups according to the disclosed content of the utility model, the technical scheme of three groups of above exhaust tubes can become the exhaust tube man-made division more than three groups according to actual needs, at this moment need to carry out the how logical operation valve of any gating to the sampling pipe for the treatment of more than three according to the grouping situation of exhaust tube is next supporting, the how logical operation valve group that constitutes of the many valves in multidigit various way solenoid valve or multitube road is for example carried out each only logical one and the gating of closing other stopple coupons to be measured is controlled by many logical operation valves or valve group to the total stopple coupon on all stopple coupons to be measured and its gas outlet; The Comprehensive Control of the line arrangement mode of above various feasible programs and each valve or valve group all is prior aries that the general field technician is grasped, and describes in detail no longer one by one herein.
In addition, the link position of the inlet end for the treatment of stopple coupon in the foregoing description in the single channel tracheae of bleed-off passage is the side of giving vent to anger of the aspiration pump that communicates with gas outlet after aspiration pump, before the exhausr port, because the position of aspiration pump on the single channel tracheae is general relatively near exhausr port generally speaking, such layout purpose is to enter stopple coupon to be measured in order to reduce the length for the treatment of stopple coupon and to be convenient to gas.But; such layout is not got rid of in some cases; the link position of inlet end in the single channel tracheae of bleed-off passage for the treatment of stopple coupon is on the unipath tracheae of the aspiration pump air inlet side before the aspiration pump; when not considering that duct length and aspiration pump are a plurality of; such arrangement is feasible; but such variation belongs to the technical characterictic that is equal to replacement; compare with the technical solution of the utility model, only have to be equal to and replace the different technical scheme of feature and must belong to protection domain of the present utility model.
