The air bag sampler comprises a collection device, a power device and a collection box, wherein the collection device is positioned in the collection box, and the power device is communicated with the interior of the collection box through a guide pipe; the collection box consists of a box cover and a box body, the collection device consists of an air inlet valve, a tee joint, an air outlet valve, a nozzle and an air bag; the air inlet valve and the air outlet valve are arranged on a box body, and are communicated with two opening ends, facing towards the box body, of the tee joint arranged in the box body, another opening end, deviating away from the box body, of the tee joint is communicated with the air bag through a guide pipe; the air bag is arranged at the bottom of the box body, the nozzle is arranged on the box body, and the external power device is communicated with the inner side of the box body. The air bag sampler has the beneficial effects of being simple in structure, convenient to operate, and capable of improving the working efficiency.
Description
Technical field
The utility model relates to a kind of vacuum tank airbag sampling thief, belongs to environmental monitoring field.
Background technology
Air quality for monitoring environment, need to gather sampling to the air of monitoring point, existing collection gas sample is generally vacuum tank, on it, there is dismountable gland bonnet, two pipe adapters on gland bonnet, connect respectively vacuum pump and tested scene, but complicated for the cleaning of collection bag, need to constantly tear pipe, tubulature open, very time-consuming and inconvenient.
Utility model CN200986501Y discloses a kind of portable gas vacuum sampling instrument bag over-sampling part, vasculum, power section of the changeable flow direction, it is characterized in that power section is that on direct current generator gland bonnet, one end is provided with left and right draft tube, the other end is provided with reversal valve.This device can be dismantled exchange tube head just can be just can clean the collection with tested gas to bladder tank, but its complex structure, inconvenience operates.
Utility model content
The deficiency existing for prior art, technical problem to be solved in the utility model is, a kind of vacuum tank airbag sampling thief is provided, it is simple in structure, convenient to operation, can increase work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of vacuum tank airbag sampling thief, comprises harvester, propulsion system and vasculum, and harvester is positioned at vasculum, and propulsion system are connected with vasculum inside by conduit; Vasculum is comprised of case lid, casing, and described harvester is comprised of gas admittance valve, threeway, vent valve, valve and airbag; Gas admittance valve, vent valve are arranged on casing, and are connected with two openends towards casing of threeway in being arranged on casing by conduit, and the openend that another of threeway deviates from casing is connected with airbag by conduit; Airbag is placed in the bottom of casing, and valve is placed on casing, and external propulsion system are connected with box inside.
Described gas admittance valve, vent valve are retaining valve.
Described gas admittance valve, vent valve, threeway all communicate with airbag, are positioned over box house or outside use.
The beneficial effects of the utility model are: the utility model, due to simple in structure, operates convenient, can increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of vacuum tank airbag of the utility model sampling thief comprises harvester 1, propulsion system 2 and vasculum 3, and harvester 1 is positioned at vasculum 3, and propulsion system 2 are connected with vasculum 3 inside by conduit; Vasculum 3 is comprised of case lid 4, casing 5, and described harvester 1 is comprised of gas admittance valve 6, threeway 7, vent valve 8, valve 9 and airbag 10; Gas admittance valve 6, vent valve 8 are arranged on casing 5, and are connected with two openends towards casing 5 of threeway 7 in being arranged on casing 5 by conduit, and the openend that another of threeway 7 deviates from casing 5 is connected with airbag 10 by conduit; Airbag 10 is placed in the bottom of casing 5, and valve 9 is placed on casing 5, and external propulsion system 2 are connected with casing 5 inner sides.
Described gas admittance valve 6, vent valve 8 are retaining valve.Gas admittance valve 6, vent valve 8, threeway 7 all communicate with airbag 10, are positioned over the inner or outside use of casing 5.
During sampling thief sampling, first airbag 10 is placed in casing 5, and the thief hatch of airbag 10 and threeway 7 are joined, again case lid 4 and casing 5 are closed and be connected and sealed, then operation power plant 2, now propulsion system 2 are by valve 9 make to be evacuated in vasculum 3 (case internal pressure is lower than environment atmospheric pressure), meanwhile, gas admittance valve 6 is opened, vent valve 8 is closed, in the collected airbag 10 of gaseous sample, during residual gas in need to replacing airbag 10, first gas admittance valve 6 is connected and washed away with nitrogen, or connection clean environment atmosphere, start propulsion system 2, to the interior inflation of vasculum 3, vent valve 8 is opened, meanwhile gas admittance valve 6 cuts out, gas in airbag 10 is discharged from, then, restart propulsion system 2, in making airbag 10, gas admittance valve 6 is filled with clean gas, and repeatedly carry out, in airbag, residual gas is replaced to airbag clean.
