Description

Technical Field

[0001] This utility model relates to the field of gas cylinder support technology, and in particular to a special support for dual-channel gas cylinder sampling. Background Technology

[0002] Petrochemical companies' laboratories use a large number of gas sampling cylinders, which vary in type, shape, and size, commonly 500mL, 1500mL, and 2500mL; some are approximately 30cm, 68cm, and 75cm in length; and diameters are approximately 7cm, 9cm, and 10cm. When using sampling cylinders for analysis, personnel expend considerable effort holding the cylinders, and there is a risk of the cylinders falling or tipping over. Furthermore, for continuous composition analysis and water content analysis of samples such as liquefied petroleum gas and propylene, the gas in the cylinder needs to accumulate at a slope to the bottom to ensure sample homogeneity and analytical repeatability. The placement of the sampling cylinder and the sampling speed directly affect the analytical results. The correct placement of the gas cylinder for sampling is to maintain a certain tilt angle and a fixed flow rate. However, this is often impossible for laboratory personnel when manually sampling by hand, firstly because the cylinder is heavy, and secondly because the tilt angle is often inconsistent, inevitably affecting sample homogeneity and thus the analytical results. This dual-channel gas cylinder sampling support is suitable for sampling commonly used gas cylinders in laboratories. It is simple to manufacture, highly practical, safe and labor-saving, and provides good repeatability of analytical results.

[0003] In petrochemical industry laboratories, gas cylinder sampling during gas analysis presents challenges. Holding the cylinder by hand requires considerable effort and carries the risk of it falling or tipping over. Furthermore, when analyzing the composition and water content of gases such as liquefied petroleum gas and propylene, the gas needs to accumulate at a slope at the bottom of the cylinder to ensure sample homogeneity and repeatability of results; however, maintaining a consistent tilt angle when holding the cylinder is often impossible.

[0004] Therefore, there is an urgent need for a support that can be used for sampling all types of gas cylinders, maintain a fixed tilt angle, and support the weight of the gas cylinders. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where handheld gas cylinders often cannot be fixed at a fixed tilt angle, and to propose a special sampling bracket for dual-channel gas cylinders.
