Abstract
Disclosed is a constant voltage gas collection metering device. The constant voltage gas collection metering device is composed of a gas collection bottle, a water tank, a gas inlet pipe and a fixing frame. The gas collection bottle is placed in the water tank reversely. A bottle body is provided with degree scales. A hollow clamping sleeve is fixed below the degree scales of the bottle body. The gas inlet pipe is arranged on the bottom portion of the water tank and communicated with the gas collection bottle. Gas can be filled in the clamping sleeve, the liquid level in the bottle and the liquid level outside the bottle are parallel, and therefore buoyancy generated by the clamping sleeve is equal to the total gravity of the bottle body and the clamping sleeve, air pressure in the bottle is equal to atmospheric pressure of the external world, and constant voltage gas collection is achieved.
Description
Technical field
The utility model relates to a kind of gas extractor, especially makes collected gaseous tension and external atmosphere pressure keep the gas collection recorder jar that equates.
Background technology
At present, the most frequently used draining water gathering of gas law of the metering method of gas volume.The draining gas extractor is comprised of gas bottle and the liquid meter of good airproof performance usually.The draining gas bottle has gas feed and liquid outlet, and all the other position sealings are intact.During the metering gas volume, gas is entered in the bottle by the gas bottle air intake opening, and liquid in the bottle is discharged in the liquid meter by liquid outlet, discharges liquid volume and is gas volume in the bottle.But, because liquid exists liquid level poor when gas bottle enters liquid meter, thereby cause the interior gaseous tension of gas bottle to be not equal to external atmosphere pressure, the gas volume that obtains not is the volume under the atmospheric pressure.
Summary of the invention
In order to overcome the deficiency that gaseous tension and external atmosphere pressure do not wait in the gas bottle, the utility model provides a kind of novel gas extractor, this device can not only measure the volume of the gas of collection, and can also make in the whole gas collection process that gaseous tension equates with external atmosphere pressure in the gas bottle, thereby make the gas volume that obtains equal volume under its normal pressure.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of constant voltage gas collection measuring apparatus, consisted of by gas bottle, tank, draft tube and fixed mount, gas bottle is inverted in the tank, scale is arranged on the body, draft tube is positioned at bottom of gullet, pass in the gas bottle, be fixed with hollow jacket below the gas bottle scale mark, air intake opening and freeing port are arranged on the hollow jacket.
The beneficial effects of the utility model are, can guarantee that whole gas collection process bottle internal gas pressure and external atmosphere pressure equate, gas bottle is simultaneously as meter, and is simple in structure.
Description of drawings
Accompanying drawing is structural representation of the present utility model, wherein:
1. fixed mount; 2. gas bottle exhausr port; 3. tank liquid level; 4. tank; 5. gas bottle; 6. scale; 7. hollow jacket; 8. liquid level in the chuck; 9. chuck air intake opening; 10. chuck freeing port; 11. draft tube; 12. liquid level in the gas bottle.
Embodiment
In order to further specify the utility model, below in conjunction with accompanying drawing examples of implementation of the present utility model are further described, described embodiment does not cause restriction to the utility model.
Example: take water as the liquid collection methane gas as example;
Collect before the gas, make in gas bottle 5 and the hollow jacket 7 and fill water, sealing gas bottle exhausr port 2 passes into a small amount of gas by air intake opening 11 in gas bottle 5.Inject air in from chuck air intake opening 9 to chuck, until liquid level 12 is concordant with tank liquid level 3 in the gas bottle, closure clamp cover air intake opening 9 and chuck freeing port 10.From gas bottle exhausr port 2 gas in the bottle is discharged, sealing gas bottle exhausr port 2 can begin gas collection.During gas collection, methane gas enters from draft tube 11, can learn a bottle interior gas volume by tank liquid level 3 indicated scales.Liquid level 8 is answered held stationary in the chuck in the gas collection process, vertically suspends to guarantee whole gas bottle 5.
Because the effect of chuck air intake opening 9 is that gas is entered in the chuck 7, thus in the situation that does not affect use, chuck air intake opening 9 can be on hollow jacket 7 optional position.
The employed liquid of the utility model should be selected flexibly according to the character of collected gas.
Claims (2)
1. a constant voltage gas collection measuring apparatus is made of gas bottle, tank, draft tube and fixed mount, and gas bottle is inverted in the tank, scale is arranged on the body, draft tube is positioned at bottom of gullet, passes in the gas bottle, it is characterized in that: be fixed with hollow jacket below the gas bottle scale mark.
2. constant voltage gas collection measuring apparatus according to claim 1 is characterized in that: air intake opening and freeing port are arranged on the hollow jacket.
