Specific embodiment
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the signal of simplification
Figure, only illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention in a schematic way.
As shown in Figure 1 and Figure 2, a kind of gas sampling assembly, including containment housing 2, sampling ball 4, the upper end of containment housing 2
Be provided with through hole 6, clamp assembly, in through hole 6, be provided with sealing ring 8, clamp assembly include L-shaped clamping plate 10, backward L-shaped clamping plate 12 with
And two jig arm 14 fixing with L-shaped clamping plate 10, backward L-shaped clamping plate 12 respectively, two jig arm 14 respectively with L-shaped clamping plate 10, backward L-shaped
The outer end of clamping plate 12 is fixed, and two jig arm 14 are arranged in a crossed manner, is respectively arranged with spring 16, kelly 20, bullet between two jig arm 14
Spring 16 is in extended state, and kelly 20 is fixed with the first drawstring 22, and a bearing pin 24 passes perpendicularly through two jig arm 14 and is fixed on
In containment housing 2, two jig arm 14 can lower end close to each other around bearing pin 24 or away from, containment housing 2 be provided with the body of rod 26,
Inflation inlet 28, the first drawstring 22 is fixing with the body of rod 26, the body of rod 26 is fixed with the second drawstring 30, is provided with keying at inflation inlet 28
Part 32, opening and closing element 32 is used for sealing up inflation inlet 28 or so that inflation inlet 28 is in communication with the outside, opening and closing element 32 and the second drawstring 30
Fixing, sampling ball 4 is included bladders 34 and is connected with bladders 34 and integrally formed sampling tube 36, and sampling tube 36 is flexible pipe, bladders 34
In containment housing 2, sampling tube 36 partially passes through sealing ring 8, and the setting of sealing ring 8 avoids outside air to enter containment housing
In 2, prevent from disturbing, sampling tube 36 is located between L-shaped clamping plate 10 and backward L-shaped clamping plate 12, and after kelly 20 comes loose, spring 16 is received
Contracting, drives L-shaped clamping plate 10 close to each other with backward L-shaped clamping plate 12, sampling tube 36 is clamped, it is to avoid gas leakage.After being collected gas,
Containment housing 2 shields to sampling ball 4, it is to avoid sampling ball 4 is placed on Bao Nei and is extruded gas leakage it is ensured that sampling quantity.
