Embodiment 1

[0075] The pressure sampling device in the present embodiment comprises: a first airtight container 10; a sampling bottle 20, the sampling bottle 20 is placed in the first airtight container 10; a first pipeline 31, and one end of the first pipeline 31 passes through the first airtight container After 10, it is opposite to the bottleneck of the sampling bottle 20, and the other end of the first pipeline 31 is connected with the experimental container to be sampled; the second pipeline 32, one end of the second pipeline 32 is connected with the first airtight container 10, and the second pipeline The second end of 32 is the gas outlet; wherein, the first airtight container 10 includes a first bottle body 11 and a first sealing plug 12, and the bottle mouth of the first bottle body 11 is sealed by the first sealing plug 12.

[0076] Pass gas into the first airtight container 10 in this embodiment, keep a certain pressure in it, and make the first pipeline 31 in this embodiment be...

Abstract

The present invention provides a pressure sampling device comprising a first closed vessel; a sample bottle, a first conduit and a second conduit, the sample bottle is placed in the first closed vessel; one end of the first conduit passes through the first closed vessel, and then faces an opening of the sampling bottle, the other end of the first conduit is connected with a to-be-sampled test vessel, one end of the second conduit is connected with the first closed vessel, and a second end of the second conduit is an air outlet end. Since during an experiment, the first closed vessel maintains a certain pressure, pressure in the test vessel drops slowly, the pressure loss of the first closed vessel is slowed, the normal operation of the experiment is ensured, and then an experiment product in the test vessel is sampled in real time.

Description

technical field [0001] The invention relates to the field of experimental sampling, in particular to a pressure sampling device. Background technique [0002] In the fire flooding experiment, the sampling of its products should meet the following sampling requirements: [0003] (1), real-time measurement; [0004] (2), withstand a certain pressure (0.5MPa); [0005] (3) Observable; [0006] (4), gas-liquid separation; [0007] (5) The system pressure and gas-liquid flow measurement will not be affected when the sampling bottle is replaced. [0008] At present, none of the sampling methods of the fire flooding device can realize multiple consecutive closed sampling during the experiment, and can only be sampled after the experiment is over, so that the mixed sample obtained after the experiment is terminated. [0009] In addition, if the sampling cylinder is replaced during the experiment, it will seriously affect the gas-liquid measurement, system pressure, etc., and th...
