Abstract
The active gas method of sampling belongs to a kind of quick, active open space or confined space gas collection method with device.The device is to complete gas collection and the output programmable necessary device of flow velocity.Traditional gas collecting equipment have individual big, inconvenient to carry, gas collecting by environment and manual operation influenceed greatly, the defect such as gas output stability difference.The patent can more accurately gather target location gas by active compound collection capsule, and reaction type output interface ensures that the device can export reliable gas stream that is stable, meeting gas flow rate requirement in any condition.This method and apparatus structure letter are thin, easy to carry and transport, have after gassy and prevent puncturing protective layer, possess reliable protective capacities.The invention uses more novel design method, and new thinking and method is provided for the summary of various gas collectings and sensing equipment.
Description
Technical field
The present invention relates to a kind of active gas method of sampling and device, belong to gas collecting, transport and analysis application neck
Domain.
Background technology
Using plastic foil sampler bag conventional gas sampling at present more.The bag exists following when sampling is exported with gas
Problem, 1）Needed during gas sampling with the use of manually or electrically gas sampler, complex operation, and have the latent of gas permeation
In danger；2）Gas sample needs to be extracted by vavuum pump when exporting, and for corrosive gas or has explosion danger gas needs
Fulfiled assignment using the special pump housing, investment is big, and potential safety hazard is more；3）Airbag rupture should not be observed, and gas sample is preserved and had with transporting
It is potentially dangerous.Patent utilization dual structure of the present invention, fully solves this problem.Make device not by external equipment with regard to energy
Realize gas collecting, positive-pressure type gas output control enable the device to using conventional meanses be applied to any gas output,
The naked-eye observation of airbag leakage point is realized in the colour liquid filling that dual structure is designed with that can permit.

The content of the invention
It is an object of the invention to provide one kind can quickly, complete independently gas sample acquisition, but also with controllable gas export
A kind of technical method and device.
Technical scheme：
To achieve the above object, the technical solution adopted by the present invention is：
Gas collection method：
Firstth, airbag is original is in vacuum state, and airbag is stacked to flat, and gas I/O port and positive-pressure type gas are defeated
Go out control mouth and be in sealing state；
When the secondth, gathering gas sample, the sealing of gas I/O port is opened, sample lines are connected；
3rd, spring constraint folder, airbag automatic air-breathing under the action of the spring are opened；
4th, gas sampling is completed, gas I/O port is resealed.
Gas output intent：
Firstth, positive-pressure type gas output control mouthful, connecting fluid controlling pump are opened；
Secondth, gas I/O port is opened, gas flow rate controller is connected；
3rd, air bag is compressed under the control of injection fluid, and gas output is completed according to specific flow velocity according to sets requirement.
Beneficial effect：
Using such scheme, patent beneficial effect embodies as follows：
1st, this method and device gas collecting are without external equipment, with initiative；
2nd, the sample descending decay of air pressure, the patented method gas sampling process power existed different from vacuum sampling method
Learn characteristic output steady；
3rd, positive-pressure type gas output control is enabled the device to by controlling fluid injection rate to adjust output gas flow flow velocity, nothing
By any gas sample using the Common fluids transfer tube that form is simple, cheap, stability is high, the programmable stream of gas is realized
Speed output；
4th, dual structure designs the colored leak detection liquid filling with that can permit, can realize the naked-eye observation of airbag leakage point, allow
System air-leakage test is more convenient.
Advantage：
1st, the technical scheme coordinate during gas sampling without external equipment, and gas sampling operation can be completed alone；
2nd, positive-pressure type gas output control can realize programmable gas flow optimized；
3rd, positive-pressure type gas output intent can be applied to corrosive gas in addition to routinely gas, toxic and harmful gas, easily
Fire the collection and output of explosion hazard gases；
4th, dual structure ensure that the security of gas, and the colour liquid filling that can permit conveniently can with the naked eye find leakage
Point.
5th, small volume after device overlapping, is easy to carry.
