Description

Technical Field

[0001] This utility model relates to the field of aviation fuel quality monitoring technology, specifically a portable vehicle-mounted aviation fuel quality monitoring device. Background Technology

[0002] The development of aviation fuel has undergone a long historical process. During the same period, various types and models of fuel systems existed. However, in essence, each historical revolution in aero engines has brought about rapid development and innovation in aviation fuel. Improvements and changes in engine performance place higher performance demands on fuels, thus driving the development of aviation fuel. Aviation fuel mainly includes aviation gasoline for spark-ignition piston engines and jet fuel for gas turbine engines. Due to its special application, aviation fuel must ensure that its quality meets various requirements. During transportation, it is easy for the fuel to contain water or contain impurities that are substandard, seriously affecting the safe and stable operation of aircraft. To prevent the inability to accurately collect samples from the most unfavorable points, it is necessary to quickly and intuitively determine the color, water content, and impurity quality of the fuel.

[0003] Currently, there are three known methods for monitoring the quality of vehicle-mounted aviation fuel: one is to perform suspended sampling analysis from the manhole on the top of the tank; the second is to perform sampling analysis from the bottom sampling port; and the third is to perform sampling analysis from the unloading port. Some vehicle models do not have a bottom sampling port, while others have a sampling port designed on the top surface of the tank. Most of these methods can only collect fuel from the top layer and cannot collect fuel from the most unfavorable points in the tank. The sampling methods are varied and there are no unified regulations. There are also problems such as the lack of a suitable sampler or the sampling not conforming to the regulations, which fails to effectively collect fuel from the most unfavorable points and is prone to erroneous judgments. Therefore, we need to propose a portable vehicle-mounted aviation fuel quality monitoring device. Utility Model Content

[0004] The purpose of this invention is to provide a portable vehicle-mounted aviation fuel quality monitoring device. It connects to the unloading port of an aviation fuel transport vehicle via a standard connector. The device closes the discharge port ball valve, opens the transport vehicle's unloading valve, and then opens the connector's operating valve. Aviation fuel inside the vehicle flows into a liquid-filled glass sight glass tube. Once the sight glass tube is full of liquid, the device observes the color, water content, and impurities of the fuel. If no abnormalities are observed, the transport vehicle's unloading valve and the connector's operating valve are closed. Then, the discharge port ball valve is opened to allow the sample to flow into the sampling container, thus solving the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a portable vehicle-mounted aviation fuel quality monitoring device, such as... Figures 1-4 As shown, it includes a standard connector 2, a connector operating valve 3, and a front sealing pipe 4. A liquid inlet pipe 13 is sealed between the standard connector 2 and the connector operating valve 3. The front sealing pipe 4 is sealed on the side of the connector operating valve 3 away from the standard connector 2. The unloading ports of existing aviation fuel transport vehicles are mostly uniform connectors. By setting up a standard connector 2, it is possible to be compatible with all aviation fuel transport vehicles as much as possible. The connector operating valve 3 is set up to prevent the residual oil in the pipe after sampling from flowing back through the liquid inlet pipe 13 and being discharged from the standard connector 2. This ensures that the oil in the pipeline after the connector operating valve 3 can be discharged through the discharge bend 8, thus making it compatible with most aviation fuel transport vehicles. At the same time, the sample is taken from the most unfavorable point at the bottom of the tank, thereby ensuring the accuracy of monitoring.

[0024] Preferably, the front sealing tube 4 has an observation assembly on its side for convenient observation of the aviation fuel condition. The observation assembly includes a glass sight glass tube 6, a rear mounting base 9, a front mounting base 10, and a sampling module. The glass sight glass tube 6 is positioned between the rear mounting base 9 and the front mounting base 10. The front mounting base 10 is sealed to the front sealing tube 4 via a connecting pipe 5. The connecting pipe 5 passes through the front mounting base 10 and is sealed to the glass sight glass tube 6. Several sets of bolting rods 21 are bolted between the rear mounting base 9 and the front mounting base 10. The glass sight glass tube 6 is located between these sets of bolting rods 21. The sight glass tube 6 is placed between the rear mounting base 9 and the front mounting base 10. Then, by bolting several sets of bolting rods 21 between the rear mounting base 9 and the front mounting base 10, the distance between the rear mounting base 9 and the front mounting base 10 is controlled. At the same time, the sight glass tube 6 is protected by several sets of bolting rods 21 around it. The sight glass tube 6 is transparent and oil is put into the sight glass tube 6. After the liquid level inside the sight glass tube 6 is stable, the color, water content and impurity quality of aviation fuel in the glass tube can be observed. The operation is simple and the quality of the oil can be observed intuitively.

[0025] Furthermore, the sampling module includes a discharge ball valve 7, a discharge bend 8, and a discharge pipe 14. The discharge pipe 14 passes through the rear mounting base 9 and is sealed to the glass sight glass tube 6. The discharge ball valve 7 is sealed on the side of the discharge pipe 14 away from the glass sight glass tube 6, and the discharge bend 8 is sealed on the side of the discharge ball valve 7 away from the discharge pipe 14. The oil inside the glass sight glass tube 6 flows into the discharge ball valve 7 through the discharge pipe 14. When sampling is required, the discharge ball valve 7 is opened to discharge the oil from the inside of the discharge bend 8, thereby facilitating sampling while achieving quantitative sampling, avoiding waste or affecting the monitoring effect caused by excessive or insufficient sampling.

[0026] Furthermore, an installation ring 12 is fixedly installed on the outer arc surface of the front sealing tube 4, and two sets of operating rods 11 are symmetrically arranged on the outer arc surface of the installation ring 12; a standard connector protective cover 1 is threadedly connected to the side of the standard connector 2 away from the infusion tube 13, and a connecting rope 16 is fixedly connected to the outer arc surface of the standard connector protective cover 1, and the other end of the connecting rope 16 is fixedly connected to the installation ring 12; an internal thread 18 is opened on the inner arc surface of the standard connector protective cover 1, and an external thread 17 corresponding to the internal thread 18 is opened on the outer arc surface of the standard connector 2. The operating rods 11 are provided to facilitate the connection of the whole device to the transport vehicle, and the standard connector protective cover 1 is threadedly connected to the external thread 17 on the outer arc surface of the standard connector 2 through the internal thread 18, thereby preventing dust from entering the standard connector 2 when not in use. At the same time, it is connected to the installation ring 12 through the connecting rope 16 to prevent the standard connector protective cover 1 from being easily lost after being removed.

[0027] Specifically, the outer arc surface of the standard connector 2 is provided with a grounding wire 15, one end of which is connected to a grounding clamp 20. The outer arc surface of the standard connector 2 is also provided with a placement hook 19 corresponding to the grounding clamp 20. The grounding wire 15 and the grounding clamp 20 are used to ground the device to avoid static electricity affecting the safety of the operation process. At the same time, the placement hook 19 is provided to facilitate the placement of the grounding clamp 20 when it is not in use.

[0028] Working Principle: Utilizing the standard model of the unloading port for land-transported aviation fuel, this system adds a connector operating valve 3, a glass sight glass tube 6, a discharge ball valve 7, and a discharge elbow 8. When monitoring the aviation fuel inside the tank is required, the standard connector 2 is connected to the unloading port of the tank. Then, the grounding clamp 20 is grounded, and the unloading valve and connector operating valve 3 are opened. The aviation fuel at the bottom of the tank flows by gravity into the glass sight glass tube 6. After the liquid level stabilizes, the color, water content, and impurity quality of the aviation fuel inside the glass tube can be observed. If the color is normal, and there is no water or impurities, the system is closed. Close the unloading valve and connector operating valve 3, open the discharge port ball valve 7 to discharge the oil through the discharge bend 8, then close the connector operating valve 3 and disconnect the standard connector 2 from the unloading port of the vehicle tank. If it contains water or organic impurities, open the connector operating valve 3 to discharge the water and organic impurities from the vehicle tank through the discharge bend 8. During the operation, pay close attention to the oil condition in the glass sight glass tube 6. When the color is normal and there is no obvious water or organic impurities, close the discharge port ball valve 7. After the liquid level stabilizes, you can observe the color, water, and organic impurity quality of the aviation fuel in the glass sight glass tube 6. Repeat the above steps according to the water and organic impurity condition.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
