Description

Technical Field

[0001] The utility model relates to the technical field of aviation fuel detection, in particular to a detection device for aviation fuel. Background Art

[0002] Aviation fuel refers to some fuel varieties specially designed for aircraft. It is of higher quality than the fuel used in heating systems and cars, and usually contains different additives to reduce the risk of icing and explosion due to high temperature. Aviation kerosene has appropriate density, high calorific value, good combustion performance, can burn quickly, stably, continuously and completely, and has a small combustion area, less carbon deposits, and is not easy to coke; it has good low-temperature fluidity and can meet the requirements of oil fluidity in cold and low-temperature areas and high-altitude flights; it has good thermal stability and antioxidant stability and can meet the needs of supersonic high-altitude flights; it has high cleanliness, no mechanical impurities and harmful substances such as moisture, and low sulfur content, especially mercaptan sulfur content, and little corrosion to mechanical parts.

[0003] When water is mixed into aviation kerosene, its freezing point will increase. If the aircraft flies in cold weather for a long time, the water in the fuel will easily freeze into ice, causing the engine to interrupt or completely stop fuel supply, endangering flight safety.

[0004] Therefore, in order to ensure flight safety, aviation fuel is generally extracted for testing. When testing aviation fuel, existing test bottles only consider how to extract aviation fuel, but do not consider how to facilitate the staff to clean the test bottles after the test is completed to ensure that subsequent staff can use the test bottles to conduct aviation fuel testing again without affecting the accuracy of the test.
