Description

Technical Field

[0001] The utility model relates to the technical field of petroleum sampling, in particular to a petroleum sampling device which is easy to store. Background Art

[0002] Liquefied petroleum gas is a mixture of various gases, including propane, butane, isobutane, n-pentane, etc. Their content and proportion have a great influence on the properties and uses of petroleum gas. Sampling technology can help separate, purify and measure these gas components to determine the composition and characteristics of petroleum gas.

[0003] According to a disclosed oil sampling device with cleaning function (publication number: CN219757809U), in the above application, during the use of oil sampling, the winding wheel is driven by rotating the plug handle to release the line, so that the sampling tube falls in the oil storage tank. When it reaches the specified scale position, it stays for a period of time and then reels in the line to sample the oil.

[0004] However, during actual use of the above-mentioned equipment, oil is sampled through a sampling tube, but the oil cannot be preserved after sampling. After the oil is sampled, if the oil is not used for subsequent processes for a long time, the oil temporarily stored in the sampling tube cannot be well preserved, which increases the contact time of the oil with the air and increases evaporation. At the same time, the oil cannot be placed at a relatively low temperature when stored, thereby increasing the evaporation of the oil. In view of this, we propose an oil sampling device that is easy to preserve. Utility Model Content
