Description
Technical field
The utility model and experiment field, be specifically related to a kind of vacuum extractor of gas cylinders for gathering Soil Trace Gases.
Background technology
As the important emission source of global warming gas, soil CH
4, CO
2and N
2the monitoring of O isothermal chamber gas discharging is widely paid close attention to, and needs to gather associated gas and measures.Before mensuration, generally by the airbag of certain volume (as the sampler bag that Dalian De Lin gas packed packaging company limited produces) or little gas production bottle, gas collection is got up.Before gas production, need to vacuumize process to airbag or gas production bottle, in order to avoid assorted gas pollutes associated gas.Compared with gas cylinder, airbag volume is comparatively large, and the gas flow of needs is more.At present, the work carrying out Soil Trace Gases mensuration is mainly carried out in laboratory examination and field in-situ test, and the generation of both gases differs greatly.Laboratory cultures is tested, device in order to measure greenhouse gases is relatively little, as volume be the triangular flask of 100-250mL as culture apparatus, the gas generated of extraction may be not enough to Filling air bag, cause laboratory cultures test soil gas effectively can not be collected and measured.By equipment such as " a kind of mancarried device for collecting wheatland greenhouse gases " (number of patent applications 201320241810), field acquisition gas in enormous quantities, available airbag is as airbag gathering-device, but transport inconvenience or impermeability are preserved poor.As gas conserver, it is particularly necessary that gas production bottle substitutes airbag, and precondition is that before sampling, gas cylinder should be vacuum.At present gas production bottle is vacuumized in the following way: the rubber plug being sealed in bottleneck by the needle pierces of syringe, then by pull piston rod, the air in gas production bottle is extracted out, make gas production bottle reach the state of vacuum.Aforesaid operations can not make the state reaching vacuum in gas production bottle completely on the one hand, causes the gas of collection impure and the accuracy of impact experiment; Extracted out by air in gas production bottle additionally by pull piston rod, work efficiency is not high.
Utility model content
In sum, in order to solve existing technical matters, technical problem to be solved in the utility model is to provide a kind of vacuum extractor of gas cylinders for gathering Soil Trace Gases.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of vacuum extractor of gas cylinders for gathering Soil Trace Gases, comprise lid and hollow and the cylindrical shell of upper opening, the dismountable upper opening place being sealed in described cylindrical shell of described lid, described inner barrel forms evacuated chamber;
Described lid is provided with screw rod, and the lower end of described screw rod is in described evacuated chamber, and the lower end of described screw rod is connected with platen, and the upper end of described screw rod is through connecting the revolving part that can regulate described platen position after described lid;
What described cylindrical shell was provided with connection vacuum pump vacuumizes connector and air intake opening, and on described air intake opening, be provided with the valve of opening or closing described air intake opening.
Further, described lid is provided with the tensimeter of the air pressure measuring described evacuated chamber.
Further, the periphery on described covered body wall is provided with a circle flange.
The beneficial effects of the utility model are: the vacuum extractor that the utility model provides, vacuumizing for gas production bottle under vacuum pump External Force Acting, complete the bottleneck while vacuumizing, rubber bottle holder being sealed up gas production bottle, after vacuumizing end, rotary screw, with the bottle holder making platen push down gas production bottleneck, opens air intake opening valve with ventilation, opening cover, take out gas production bottle, the threaded lid of gas production bottleneck is screwed, ensure vacuum tightness in gas production bottle; Work efficiency is greatly improved additionally by vacuum pump evacuation.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In accompanying drawing, the list of parts representated by each label is as follows:
1, lid, 2, cylindrical shell, 3, evacuated chamber, 4, screw rod, 5, platen, 6, revolving part, 7, connector, 8, air intake opening, 9, valve, 10, flange.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of vacuum extractor of gas cylinders for gathering Soil Trace Gases, comprises lid 1 and hollow and the cylindrical shell 2 of upper opening, the dismountable upper opening place being sealed in described cylindrical shell 2 of described lid 1, and described cylindrical shell 2 inside forms evacuated chamber 3.What described cylindrical shell 2 was provided with connection vacuum pump vacuumizes connector 7 and air intake opening 8, and on described air intake opening 8, be provided with the valve 9 of opening or closing described air intake opening 8.
When gas production bottle is vacuumized, the rubber bottle holder semi-closure corresponding with bottleneck is placed in bottleneck, vacuum pump evacuation is opened after valve-off 9, after vacuumizing and continuing for some time, can reach certain vacuum tightness in evacuated chamber 3, namely also reach vacuum state in gas production bottle, semi-closure is in the rubber plug of bottleneck, can be pressed in bottleneck completely in the process that above-mentioned air pressure converts, realize sealing up gas production bottle after gas production bottle reaches vacuum state.
Described lid 1 is provided with screw rod 4, and the lower end of described screw rod 4 is in described evacuated chamber 3, and the lower end of described screw rod 4 is connected with platen 5, and the upper end of described screw rod 4 is through connecting the revolving part 6 that can regulate described platen 5 position after described lid 1.After stopping vacuum piping operations, rotate revolving part 6, drive platen 5 to move downward by screw rod 4, until platen 5 pushes down the rubber bottle holder of gas production bottle top bottleneck, time namely rotation revolving part 6 is subject to resistance, now rotates revolving part 6 more a little and just can.Aforesaid operations is to prevent some rubber plug not sometimes to be pressed in bottleneck completely due to extraneous factor, again pressing down rubber plug, ensure to adopt in gas bottle the sealing after reaching vacuum state.Finally the valve 9 of air intake opening 8 is opened, air enters in evacuated chamber 3 from air intake opening 8, when air pressure in evacuated chamber 3 is consistent with atmospheric pressure, just can opening cover 1, take out in evacuated chamber 3 and complete the gas production bottle vacuumized, the threaded lid of gas production bottleneck is screwed, ensures vacuum tightness in gas production bottle.
Described lid 1 is provided with the tensimeter 10 of the air pressure measuring described evacuated chamber 3, judges the vacuum state in evacuated chamber 3 by the reading of tensimeter 10, determine whether vacuum pump continues to vacuumize.The periphery of described lid 1 is provided with a circle flange 11, and hand-held flange 11 is to be more prone to transfer or to install lid 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
