Abstract
A kind of anti-gas-leak sample body sampling bag, belongs to gas sampling field of containers.Because conventional gas sampling bag does not have anti-drip valve, because the pressure of bag intracavity gas is higher than environment atmospheric pressure in button mouth lid process, therefore the gas sample in bag chamber can inevitably flow out, and even also has air and is mixed in sampling bag, causes gas sample deficiency or distortion.The utility model is not when changing the essential structure of raw-gas sampling bag, by setting up an anti-drip valve at bag mouth towards bag chamber end, reach the effect preventing gas sampled from leaking, mix releasing-joint simultaneously, reach convenient and sample gas in sampling bag is taken out the object carrying out chemically examining.This gas sampling bag has simple structure, easy to operate, can effectively prevent from causing the problem such as undersampling or distortion because sample gas leaks in sampling process, to avoid again in Sample preservation and transportation, because of the leakage accident that careless manipulation causes, being convenient to the advantages such as procedure release.
Description
Technical field
The utility model relates to a kind of leakproof gas sampling bag, belongs to gas sampling field of containers.
Background technology
Current existing gas sampling collecting bag is made up of bag, bag chamber, bag mouth and mouth lid mostly.Before sampling, bag chamber is in vacuum state.First open mouth lid during sampling, by bag mouth, gas sample is pressed into bag chamber, then buckle mouth lid.Because conventional gas sampling bag does not have anti-drip valve, because the pressure of bag intracavity gas is higher than environment atmospheric pressure in button mouth lid process, therefore the gas sample in bag chamber inevitably flows out, and even also has air and is mixed into sampling bag chamber, causes gas sample deficiency or distortion.
Summary of the invention
The defect that in its sampling process, gas sample easily leaks is improved on the basis that the utility model is intended to original gas sampling bag, improves convenience and the reliability of gas sample.
A kind of anti-gas-leak sample body sampling bag, comprise bag (1), bag chamber (2), bag mouth (4), mouth lid (5), it is characterized in that: the one end being also included in the bag mouth (4) in a bag chamber (2) is provided with anti-drip valve (3).
Further, in bag mouth (4), releasing-joint (6) is also set.
Further, wherein releasing-joint (6) one end diameter is large, and other end diameter is little,
Further, one end that wherein releasing-joint (6) diameter is large is flat mouth, and one end that diameter is little is groove.
Further, wherein said groove is seen as one section of outwardly camber line from side view.
More specifically scheme is:
Gas sampling bag of the present utility model is made up of bag (1), bag chamber (2), anti-drip valve (3), bag mouth (4), mouth lid (5) and releasing-joint (6).See Fig. 2, wherein to connect (6) first end diameter bigger in release, and other end diameter is smaller, and one end that diameter is large is flat mouth, and one end that diameter is little is groove, wherein groove height H, long L, and H≤L≤2H; Note initial 2 of groove is A, B, and groove sideline is through A, B 2 and outwardly circular arc.By increasing a movable leak proof valve (3) at bag mouth (4) towards the one end of bag chamber (2), and configure a sample releasing-joint (6), both prevented the leakage of gas sample in sampling process, convenient taking-up by gas sample is tested again.The utility model is applicable to all kinds of gas sample such as medical chemical examination and gas environmental monitoring.
The utility model has the advantage of: when not changing the essential structure of raw-gas sampling bag, by setting up an anti-drip valve (3) at bag mouth (4) towards bag chamber (2) end, reach and prevent gas sampled leakage effect, mix releasing-joint (6), reach convenient object of sample gas in sampling bag being taken out chemical examination.The utility model gas sampling bag has simple structure, easy to operate, can effectively prevent from causing the problem such as undersampling or distortion because sample gas leaks in sampling process, can avoid again because of the leakage accident that careless manipulation causes in Sample preservation and transportation, also be convenient to the advantages such as procedure release simultaneously.
Accompanying drawing explanation

Fig. 2: releasing-joint enlarged drawing
Fig. 3: inflation sampling process figure
Fig. 4: inflated figure
Fig. 5: sample gas dispose procedure figure
In figure: 1 bag; 2 bags of chambeies; 3 anti-drip valve; 4 bags of mouths; 5 gland bonnets; 6 releasing-joints; 7 assay apparatus receiving ports.
Embodiment
Gas sample is generally be pressed in bag chamber (2) by certain pressure by gas sample, pressure now in bag mouth (4) is greater than the pressure in a bag chamber (2), anti-drip valve (3) is pressed towards a bag chamber (2), and sample gas enters a bag chamber (2).When after gassy sample in bag chamber (2), pressure in bag chamber (2) is greater than a bag mouth (4), anti-drip valve (3) is pressed towards a bag mouth (4) and is closed, and then plays and prevent the sample gas in a bag chamber (2) from exposing.Guaranteeing not leak in preservation or transportation at gas sample, need at the upper fastening sealing lid (5) of bag mouth (4).The utility model can prevent the leakage situation of gas when sampling effectively, and then reaches the effect of convenient sampling.When carrying out chemical examination and measuring, the flat mouth end of releasing-joint (6) is enclosed within assay apparatus receiving port (7), then take off the gland bonnet (5) of sampling bag, the bag mouth (4) of sampling bag is inserted on releasing-joint (6).Diameter due to releasing-joint (6) is that one end is large, one end is little, when releasing-joint (6) is about to be formed closely connected between bag mouth (4), the bevel end of releasing-joint (6) backs down anti-drip valve (3), and sample gas is released in assay apparatus.
Based on this, the technical solution adopted in the utility model is a kind of leakproof gas collecting bag, this leakproof gas collecting bag
The above; it is only essential characteristic of the present utility model; not any pro forma restriction is done to the utility model; anyly do not depart from technical solutions of the utility model content; according to technical spirit of the present utility model; do within thought of the present utility model and principle any amendment, equivalent variations and modification, all should be considered as the technology category of the utility model scheme, all should be included in protection domain of the present utility model.
