Aviation fuel refers to a fuel variety specifically designed for aircraft, and has a higher quality than fuel used in heating systems and automobiles, and generally contains different additives to reduce the risk of icing and explosion due to high temperature. The aviation kerosene has the advantages of proper density, high heat value, good combustion performance, rapid, stable, continuous and complete combustion, small combustion area, less carbon deposition and difficult coking; the low-temperature fluidity is good, and the requirements of cold low-temperature areas and high-altitude flight on the fluidity of oil products can be met; the thermal stability and the anti-oxidation stability are good, and the requirement of supersonic high-altitude flight can be met; high cleanliness, no harmful substances such as mechanical impurities and water, low sulfur content, especially low mercaptan sulfur content, and less corrosion to machine parts.

Aviation fuel is typically carried by fuel trucks to a parked aircraft or helicopter. However, there are also airports that have gas stations to which the aircraft needs to taxi for refuelling. And underground oil pipes are laid in some large airports and are connected to all berths, and the airplane only needs to refuel through a pump truck. There are two ways of refueling, including above-wing and below-wing. Wing fueling is used on small aircraft, helicopters and all reciprocating engine aircraft, opening one or more fuel tanks and fueling with a conventional fuel pump, similar to automobile fueling. Under-wing refueling, also known as single-point refueling, is used on large aircraft using aviation kerosene and is connected with a refueling port by a high-pressure choke, and then an oil pump is used for pumping oil into a tank by a pressure pump of 50 PSI. Since there is only one refueling point, the fuel distribution between the tanks is controlled by the refueling point control panel or the cockpit.

Because aviation kerosene need refuel through the tank service truck when filling, no matter whether have the batch oil tank structure, all can set up the filter structure on the tank service truck, guarantee to pour into the oil in the aircraft and accord with the standard through the filter. However, the operation state of the filter cannot be checked on the old refueling truck, the filter can only be detached for maintenance and inspection regularly, and once the filter fails, the water content of kerosene injected into the aircraft is increased, so that the engine efficiency of the aircraft is affected, and meanwhile, serious potential safety hazards are brought.

Example 2:

the present embodiment also discloses a filter pipeline moisture detection module for a fuel tank truck, which is defined by optimizing the structure of the moisture filter based on the above embodiment 1, wherein as shown in fig. 5 to 10, the device is provided with a screw thread, and the device is screwed on the opening at the lower part of the four-way pipe, so that the device can be contacted with the internal fluid for detection in a state of ensuring the complete sealing of the pipeline.

In fig. 9, the probe 6, the insulating base, the insulating sleeve, the fixing base and the restraining member are arranged from top to bottom.

In fig. 10, the nut assembly for fixing the tail of the probe 6 can be seen, from left to right, as a tightening nut, two washers and a compression nut.

The main body part of the device is a fixed seat structure which is a pipe body, and an operable hexagonal nut structure is arranged outside the pipe body, so that the device can be conveniently screwed on a four-way pipe by using tools. The fixing seat is provided with a thread side connected with the four-way pipe, and the fixing seat is internally provided with an integrally formed fixing plate structure which divides the inside of the fixing seat into two parts through a fixing plate. Wherein, one side facing the four-way pipe is provided with a sinking groove, and two needle-shaped electrodes with parallel axes are arranged in the sinking groove.

The needle electrode is made of metal material, and the partial surface of the needle electrode existing in the detection area is coated with corresponding electrode material. And two jacks are arranged on the fixed plate, an external thread structure is arranged at the bottom of the needle-shaped electrode, one end provided with an external thread penetrates through the jacks, and the other end is screwed and fixed through a tension bolt arranged on the other side.

In fig. 9 and 10 it can be seen that for ease of fixation four small stop formations, i.e. locating pins, are provided on the surface of the needle electrode adjacent the externally threaded portion. When the tightening nut is screwed, the positioning pin can limit the needle-shaped electrode to completely pass through the jack, so that the needle-shaped electrode is fixed on the fixing plate.

Furthermore, in order to avoid the direct contact between the needle electrode and the metal fixing seat, a cylindrical insulating seat structure is arranged in the sinking groove. As can be seen, the insulating base is hollowed at one side and protrudes in the hollowed area to form two cylindrical structures, and a hole is formed in the inner part of each cylindrical structure, wherein the inner diameter of the hole is not larger than the section diameter of the needle-shaped electrode, so that the needle-shaped electrode is wrapped.
