The butt end of the draw-in groove 5 that described two symmetrical semi-circular shape parts are formed, what be provided with traction action buckles 7 and link.
Described gas outlet 9, its upper port exceeds cover 2 upper surface, and lower port is concordant with cover 2 inside surface.
The utility model, relative to prior art, has following advantage and effect:
The utility model, arranges the liquid that fluid cylinder holds in tank body, absorb the shale gas of sample solution sucking-off, coal-seam gas, reduces the gas concentration in tank interior space (namely around sample) in time, realizes the fast desorption of shale gas, coal-seam gas.
The connection of the utility model cover and tank body, adopt the draw-in groove that two symmetrical semi-circular shape parts are formed, the inner side of draw-in groove has groove, tank body upper port has an outer rim, the periphery of cover has an outward flange, the outer rim of tank body and the outward flange of cover embed in the groove of draw-in groove, and are provided with O-ring seal in groove.There is the advantages such as convenient disassembly, good sealing effect, technological means be easy.
The utility model is the fast desorption of a large amount of sample, and the testing efficiency improving shale air content provides technical support.
