英语单词gas sample tube的用法讲解

Gas sample tube, also known as sample tube, is a kind of sample container used to collect and store gas samples. It is widely used in various fields such as petrochemical, chemical, power plant and environmental protection for sample analysis and teaching demonstration.

Gas sample tube is mainly composed of two parts, namely cylinder tube and end cap. The cylinder tube is made of stainless steel and has a fixed length. The cylinder tube is sealed at one end and the other end is connected with a valve. The valve can be opened or closed to control the gas flow in or out of the tube. The end cap is connected to the cylinder tube and is used to connect the tube and the external pipes, valves and other equipment.

The main function of the gas sample tube is to collect and store samples. It is usually used to collect and store air samples for analysis of oxygen, carbon dioxide, sulfur dioxide and other components, in order to monitor and control the air quality in industrial areas. In addition, it can also be used to detect the content of carbon monoxide and other flammable and explosive gas components in gas pipelines.

In operation, the tube should be installed upright on the sampling point, and the valve should be opened to normal operation pressure until the gas flows into the tube. The valve should then be closed and the sample can then be collected for analysis. In order to maintain the consistency and accuracy of the collected sample, the valve should not be opened and closed frequently. After use, the sample tube should be cleaned and dried thoroughly and stored in a cool, dry and dust-free environment.

Gas sample tube is an important sampling device, therefore, it is necessary to pay attention to its maintenance in daily use, and check it regularly to ensure its normal operation. In addition, the sample tube should not be subjected to strong impact and vibration, and it should be operated properly to avoid accidents.
