Description

Filter detection pipeline of oil refueling truck

Technical Field

The utility model belongs to the technical field of the supply equipment of aviation fuel, concretely relates to filter of aviation fuel tank service truck detects pipeline.

Background

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. And the existing old-fashioned oil tanker is not provided with equipment for directly detecting the water filtering performance of the filter, and the potential safety hazard can occur because the common detection equipment is directly arranged in the filter.

This pipeline structure is through changing the cross-pipe structure, under the prerequisite that does not influence the normal blowdown of filter 1, can in time contact the discharge waste material of filter 1 to in time acquire the operating condition that the waste material moisture content reacts this filter 1, provide the maintenance reference for corresponding staff.

Example 2:

the present embodiment also discloses a detection pipeline of a filter 1 of a fuel tanker, which is the same as the above embodiment 1, and is also arranged at a sewage discharge pipe outlet at the lower part of the filter 1, and a water content detector 10 is butted through a sewage discharge multi-head pipe 2. But in order to further improve stability and security, blowdown bull pipe 2 in this embodiment is three-way pipe structure, increases a container that has certain volumetric on the normal pipeline of one side originally, piles up a certain amount with the exhaust waste material in this space, can avoid because of the discharge and be in the undulant great influence detection accuracy of material moisture content of mobile state.

Specifically, the drainage tube 3 shown in the figure is a hard tube structure and is communicated with a manual valve at one side of the blowdown manifold 2 through threads. And the drainage tube 3 is raised upwards in the right side and vertically extends upwards for a certain length to be connected to the lower end of the detection pot 4, and then a discharge pipe 5 extending downwards is arranged on one side of the detection pot 4 to discharge the waste accumulated in the detection pot 4.

Since the additional detection pot 4 and its piping structure have a certain mass, if it is directly fixed at the waste discharge manifold 2 and the weight is borne by the structure, it may cause structural damage to the connection. Then, a fixing structure is added in this embodiment to fix the whole added pipeline structure on other structures.

Specifically, the fixing structure comprises a clamping belt 6 and a fixing part 8, wherein the clamping belt 6 is fixed on a cylindrical structure at the lower part of the filter 1 in the figure, the fixing part 8 is connected with the clamping belt 6 and extends downwards to form a clamping ring 11 structure for supporting the whole detection kettle 4, and the detection kettle 4 is large in size, so that a supporting effect is provided for the drainage tube 3 and the drainage tube 5 by fixing the detection kettle 4.

As shown in fig. 9 and 10, the main structure of the fixing member 8 is attached to the cylindrical structure surface of the lower end of the filter 1, and the fixing member 8 is provided with a pull ring 8.2 at one side and a spline 8.1 at the front side. One end of the clamping strap 6 is sleeved on the pull ring 8.2 and can rotate around the pull ring 8.2. After winding the round with strap 6 around cylindric structure, with its other end taut back and make its tip have the surface laminating of a plurality of latches in the draw-in groove, thereby it compresses tightly and fixes this tip in the draw-in groove to have fastener 7 through buckling from the outside to thereby realize whole strap 6 and the fixed of mounting 8 with the bolt after fixing fastener 7.

Further, in order to improve the detection accuracy, as shown in fig. 10, the inner bottom of the detection pot 4 has a curved surface, which enables the liquid substance entering from the drainage tube 3 to be at the highest point after entering the detection pot 4 and spread outwards along the curved surface, and the lowest point is at the outer bottom of the detection pot 4, where there is an opening communicating with the drainage tube 5. And a moisture detector 10 is fixed on the top of the detection pot 4 in a threaded fit manner. The moisture detector 10 has two probes, which extend into the detection port of the drainage tube 3, and the detection port is expanded outwards, so that more liquid substances can be ensured to stay at the detection port as much as possible. The outer wall of one side of the detection pot 4 is hollowed, and a transparent window 4.1 structure is arranged at the hollowed part, so that a user can observe the discharge state from the outside.

Because solenoid valve 9 and moisture detector 10 are connected with outside detection circuitry's control module, are equipped with level sensor in detecting kettle 4 simultaneously, are controlled the material volume that gets into by control module, guarantee to have the contact of sufficient material water supply partial detector 10 in detecting kettle 4 to improve the accuracy.

The present invention is not limited to the above-mentioned alternative embodiments, and various other products can be obtained by anyone under the teaching of the present invention.
