Automatic gas sample retention device

Abstract

The invention discloses a full-automatic gas sample retention device. The full-automatic gas sample retention device is characterized by comprising a sample gas retention pump, wherein the input end of the sample gas retention pump is used for connecting with a sample gas pipeline, the output end of the sample gas retention pump is connected with a sampling pipe via a flowmeter, and an evacuation valve for evacuating gas in an evacuation pipe is arranged at the tail end of the sampling pipe; a gas bag connection zone is arranged on the sampling pipe between the flowmeter and the evacuation valve, a plurality of gas bags are connected on the gas bag connection zone through branch pipes, and a communicating valve is arranged on each branch pipe; and the full-automatic gas sample retention device further comprises a controller, and the sample gas retention pump, the flowmeter, the evacuation valve and the communicating valves are electrically connected with the controller. The full-automatic gas sample retention device can be used for realizing automatic precise sample retention of gas, improving the production efficiency and saving the labor cost; and meanwhile, the full-automatic gas sample retention device can be used for ensuring that the gas has no pollution and no loss during the whole process and improving the accuracy in follow-up gas sample verification analysis.

Description

technical field [0001] The invention relates to a fully automatic gas sample retention device. Background technique [0002] Gas sample retention is an important link in the process of gas production and detection. For gases that do not meet the standards (such as the polytetrafluoroethylene gas currently produced by the company, it has chemical stability, non-stickiness, lubricity, electrical insulation, and aging resistance. And many advantages of radiation resistance, usually used as lining materials, which need to be tested before leaving the factory), must be extracted and stored in one or more air bags for subsequent verification, analysis and verification. [0003] The current conventional practice relies on manual sample retention, which not only takes time and effort, but also makes the company bear a lot of labor costs. For gas samples that exceed the standard, it is difficult for workers to control when to retain samples and how much to retain. It is very likely ...

Problems solved by technology

[0003]Current conventional methods rely on manual sample retention, which not only takes time and effort, but also makes the company bear a lot of labor costs. Control when the sample should be retained, and how much to retain, it is very likely that the most representative sample gas will be missed or the amount of gas required for the verification will not be retained, which will bring inconvenience to future research and verification

[0004]In addition, the existing artificial gas sample retention process can easily cause pollution and loss of the reserved gas due to improper operation, resulting in inaccurate subsequent verification and analysis results , not reaching the intended purpose
