Cabin 2, piston portion 3, gas abjection check valve 4, gas collection check valve 5, gas production bag 6, gas flowmeter 7 and supersonic generator
8.At least one end of cylinder 1 is closing.
Sample chamber 2 is arranged in cylinder 1, and sample chamber 2 is closed vacuum cavity.Piston portion 3 is arranged in cylinder 1, sample
The top in product cabin 2, the external diameter of piston portion 3 and the internal diameter of cylinder 1 are adapted.The external diameter and cylinder of piston portion described in the utility model
The internal diameter of body refers respectively to the external dimensions of piston portion and the inside dimension of cylinder, when cylinder 1 is cylinder, the also phase of piston portion 3
It should be circular, the external diameter of piston portion just refers to the external diameter of circle, and the internal diameter of cylinder just refers to the internal diameter of cylinder, when cylinder is square
Cylinder or during other polygon cylinders, piston portion also mutually should be square or other polygons, the external diameter of piston portion just refer to it is square or its
The external dimensions of his polygon, the internal diameter of cylinder just refer to square tube or the logical inside dimension of other polygons, i.e. piston portion 3
Shapes and sizes are identical with the shapes and sizes inside cylinder 1.Piston portion 3 can move back and forth up and down along the axis direction of cylinder 1,
Piston portion 3 can use motor or cylinder or Driven by Hydraulic Cylinder.
Gas deviates from check valve 4 and gas collection check valve 5 is arranged on the roof of sample chamber 2, wherein, gas abjection is single
It is arranged to valve 4 in connection sample chamber 2 and cylinder 1 between the roof of sample chamber 2 and piston portion 3 in the passage in space, gas collection
Check valve 5 is arranged in connection cylinder 1 between the roof of sample chamber 2 and piston portion 3 in the passage of space and flowline 9, gas production
Another termination gas production bag 6 of pipeline 9.Gas flowmeter 7 is arranged on flowline 9, can be adopted to flowing through the entrance of flowline 9
The flow of the gas of airbag 6 is counted.The roof of sample chamber 2 is actual to be arranged at the demarcation strip in cylinder 1, and demarcation strip is in cylinder
A closing space is separated out in body 1 as sample chamber, its complementary space in sample chamber and cylinder is isolated.
