Description

Technical Field

[0002] Diesel is a light petroleum product, a mixture of complex hydrocarbons (with about 10 - 22 carbon atoms), and is a fuel for diesel engines. It is mainly prepared by blending diesel fractions produced from processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced from shale oil processing and coal liquefaction. It is divided into two categories: light diesel (boiling point range of about 180 - 370 °C) and heavy diesel (boiling point range of about 350 - 410 °C). When sampling diesel for inspection, a sampling device is required, and the operation of traditional sampling devices is relatively cumbersome.

[0003] Chinese Patent CN211904771U discloses a rapid sampling device for adulterated diesel, including a sampling tube. One end of the sampling tube is an open end, and the other end is a closed end. A connection cover is screwed to the open end of the sampling tube. One end of the connection cover is connected and fixed with a suction pipe, and the other end of the suction pipe is connected and fixed with a suction head. A screwed sealing cover is screwed and fixed to the closed end of the sampling tube. A blocking block is arranged inside the sampling tube. At the top of the sampling tube near the closed end side, there is a branch pipe, and the branch pipe is connected and fixed with a rubber tube. A stop clip is clamped in the middle of the rubber tube, and the other end of the rubber tube is connected and fixed with a negative pressure pipe.
