Description

Technical Field

[0001] The utility model relates to the technical field of sampling detection, in particular to a portable online sampling device for a natural gas pipeline. Background Art

[0002] Natural gas is a mixture of hydrocarbons that exists deep below the surface of the earth. It is formed from the remains of plants and animals that lived millions of years ago. Over time, high temperatures and pressures transform these organic materials into fossil fuels as we know them, namely natural gas. Natural gas is stored in porous rock formations underground, including oilfield gas, gas field gas, coalbed methane, mud volcano gas and biogenic gas, and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material.

[0003] Authorization announcement No. CN215256277U3 discloses a natural gas sampling device. This patented technology is conducive to achieving the effect of sampling in a natural gas pipeline by setting a connecting pipe and a connecting pipe. The connecting pipe is connected and installed in the middle of the natural gas pipeline through a connecting sleeve. When sampling, the sampling bottle is sleeved on the upper end of the connecting head, and the movable valve is opened at the same time to allow the natural gas to be discharged outward through the connecting pipe, which is conducive to the sampling of natural gas by the sampling bottle; however, the structural design of the natural gas sampling device in this scheme is not reasonable enough, and the layout is not scientific enough. Since the joint is fixedly connected to the sampling tank, each time the sampling is connected to the outlet pipe, the hose, sampling tank and other devices need to move together, which makes the operation difficult and cannot be operated independently by a single person. It takes a long time and requires a large operating space. At the same time, the overall volume of the sampling device is large and inconvenient to carry. Therefore, a portable online sampling device for a natural gas pipeline is needed to improve the above problems. Utility Model Content
