Description

Technical Field

[0001] This utility model belongs to the field of oil sampling technology, specifically an oil sampling device for testing. Background Technology

[0002] Aviation fuel refers to the fuel used to propel aircraft engines. It is also known as aviation fuel or aviation oil. It is a general term for the working fluid in aircraft systems. Since the advent of airplanes, with the upgrading of aircraft models, aviation fuel has also developed significantly. Aviation fuel is mainly used to provide power for aircraft engines and to provide the necessary fuel for aircraft auxiliary systems.

[0003] To ensure flight safety, it is necessary to regularly sample and test the oil in the tanks. However, the tanks are generally sealed with inert gas, and the gas phase space inside the tank is filled with a mixture of inert gas and oil. If the sampling port is opened for a long time to sample the oil, some gas will be lost. Furthermore, it is difficult to accurately extract the oil from the bottom side of the tank when directly extracting and testing the oil inside the tank, which makes the oil detection structure inside the tank prone to deviation.

[0004] To address this issue, those skilled in the art have proposed a sampling device for oil detection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sampling device for fuel testing, thereby solving the problem of inconvenient sampling of aviation fuel in the prior art.

[0006] A sampling device for oil testing includes: a receiving plate for limiting and engaging with the sampling port of an oil tank; a connecting mechanism disposed on the receiving plate for limiting and connecting the receiving plate; a sampling mechanism engaged within the receiving plate for sampling oil from the oil tank; and a sealing mechanism rotatably disposed on the sampling mechanism for sealing the oil sampling of the sampling mechanism.

[0007] Preferably, the connecting mechanism includes a connecting groove located at the top center of the receiving plate, and a limiting cylinder is engaged with the receiving plate through the connecting groove; a plurality of limiting grooves are provided on the inner wall of the connecting groove, and a plurality of limiting strips are fixedly provided on the outer wall of the limiting cylinder, and the limiting grooves and limiting strips are engaged with each other.

[0008] Preferably, the connecting mechanism further includes a sealing sleeve fixedly disposed at the bottom of the receiving plate, and the sealing sleeve is connected to the connecting groove; a plurality of handles are fixedly disposed at the top of the receiving plate, and a plurality of limiting baffles are fixedly disposed on the side wall of the receiving plate.

[0009] Preferably, the sampling mechanism includes a sampling tube rotatably disposed inside the limiting cylinder, and the sampling tube has a liquid inlet on its side wall.

[0010] Preferably, the sampling mechanism further includes a sealing cap first screwed onto the top of the sampling tube, and a sealing cap second screwed onto the bottom of the sampling tube.

[0011] Preferably, the sealing mechanism includes a sealing tube rotatably disposed between the sampling tube and the limiting cylinder, the sealing tube having a connecting hole on its side wall; a connecting cylinder is fixedly disposed on the top of the sealing tube, and a sealing gasket is fixedly disposed on the inner wall of the sealing tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features a receiving plate that, when sampling oil from aviation fuel tanks, engages with the sampling port via a sealing sleeve, preventing the volatilization of the inert gas and oil mixture within the tank. A sampling tube and a sealing tube are connected via a limiting sleeve, allowing the inlet on the side wall of the sampling tube to easily penetrate the tank. The sealing tube, with its connecting hole on the side wall, can then be rotated to open and sample the oil. This facilitates sampling of oil from the bottom of the tank and improves the accuracy of oil detection. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example 1:

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a sampling device for oil testing, comprising: a receiving plate 5 for limiting and engaging with the sampling port of an oil tank; a connecting mechanism disposed on the receiving plate 5 for limiting and connecting the receiving plate 5; a sampling mechanism engaged within the receiving plate 5 for sampling oil from the oil tank; and a sealing mechanism rotatably disposed on the sampling mechanism for sealing the oil sampling of the sampling mechanism.

[0025] By incorporating a receiving plate 5, when sampling the fuel in the aviation fuel tank, the receiving plate 5 can be locked in place at the sampling port by the sealing sleeve 6, preventing the volatilization of the mixture of inert gas and oil vapor inside the tank. The sampling tube 1 and the sealing tube 7 are connected by a limiting cylinder 4, allowing the liquid inlet 14 on the side wall of the sampling tube 1 to easily penetrate into the tank. The connecting hole 15 on the side wall of the sealing tube 7 can then be rotated open to sample the fuel, thus facilitating sampling of the fuel at the bottom of the tank and improving the accuracy of fuel testing.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting mechanism includes a receiving plate 5, a sealing sleeve 6, and a limiting cylinder 4;

[0027] By providing a receiving plate 5, when sampling oil from the tank, the receiving plate 5 can be locked and engaged at the sampling port. A sealing sleeve 6 is fixedly connected to the bottom of the receiving plate 5, so that when the receiving plate 5 is engaged at the sampling port, the sealing sleeve 6 can directly seal the outer wall of the receiving plate 5 and the inner wall of the sampling port. A connecting groove 10 is provided at the top of the receiving plate 5, so that the receiving plate 5 can be easily engaged and engaged with the limiting cylinder 4 through the connecting groove 10, thereby facilitating the sampling mechanism to be engaged and engaged within the receiving plate 5 through the limiting cylinder 4.

[0028] Meanwhile, several limiting strips 13 are fixedly connected to the outer wall of the limiting cylinder 4, and several limiting grooves 11 are opened on the inner wall of the connecting groove 10. The limiting strips 13 and the limiting grooves 11 are engaged with each other, so that the limiting cylinder 4 can easily limit and engage the sampling mechanism inside the receiving plate 5 through several limiting strips 13 and limiting grooves 11, thereby facilitating the sampling mechanism to sample the oil in the oil tank.

[0029] Secondly, several handles 9 are fixedly connected to the top of the receiving plate 5, so that the receiving plate 5 can be easily held and used by the several handles 9 during installation and disassembly. Several limiting baffles 12 are fixedly connected to the side wall of the receiving plate 5, so that the receiving plate 5 can be limited and blocked by the several limiting baffles 12 during installation and use, preventing the receiving plate 5 from going deep into the sampling port.

[0030] Example 2:

[0031] refer to Figure 1 and Figure 4 The sampling mechanism includes a sampling tube 1, a liquid inlet 14, a sealing cap 1 2, and a sealing cap 2 8;

[0032] By rotating a sampling tube 1 inside the limiting cylinder 4 and opening a liquid inlet 14 on the side wall of the sampling tube 1, the sampling tube 1 can penetrate the inside of the receiving plate 5 and enter the oil tank to sample the oil through the liquid inlet 14 during use. This can reduce the volatilization of the mixture of inert gas and oil gas in the oil tank and avoid affecting the oil tank. In addition, the liquid inlet 14 on the side wall of the sampling tube 1 can easily enter the oil tank and directly sample, avoiding the problem of difficulty in sampling the oil at the bottom of the oil tank when extracting oil.

[0033] Meanwhile, a sealing cap 1 2 is screwed onto the top of the sampling tube 1, and a sealing cap 2 8 is screwed onto the bottom of the sampling tube 1. This allows the sealing cap 1 2 and the sealing cap 2 8 to be closed during sampling to prevent external air from entering the sampling tube 1. After sampling, the sealing cap 2 8 and the sealing cap 1 2 can be opened to facilitate the export of the sampled oil for testing.

[0034] refer to Figure 1 , Figure 4 and Figure 5 The sealing mechanism includes a sealing tube 7, a connecting cylinder 3, a connecting hole 15, and a sealing gasket 16;

[0035] A sealing tube 7 is rotatably connected between the sampling tube 1 and the limiting cylinder 4, and a connecting cylinder 3 is fixedly connected to the top of the sealing tube 7. This allows the sealing tube 7 to be rotated by the connecting cylinder 3 during use, sealing and protecting the inlet 14 on the outer wall of the sampling tube 1, and opening for oil sampling. A connecting hole 15 is provided on the side wall of the sealing tube 7, so that oil sampling can be performed when the inlet 14 and the connecting hole 15 correspond, and the sampling tube 1 is sealed and protected when the inlet 14 and the connecting hole 15 do not correspond. At the same time, a sealing gasket 16 is fixedly connected to the inner wall of the sealing tube 7, so that the sealing gasket 16 can improve the sealing effect of the sealing tube 7.

[0036] Working principle: The receiving plate 5 is designed to lock and engage with the sampling port when sampling oil from the tank. A sealing sleeve 6 is fixedly connected to the bottom of the receiving plate 5, allowing the sealing sleeve 6 to directly seal the outer wall of the receiving plate 5 against the inner wall of the sampling port when the receiving plate 5 is engaged. A connecting groove 10 is provided at the top of the receiving plate 5, facilitating the connection of the limiting cylinder 4. This allows the sampling mechanism to be engaged and connected to the receiving plate 5 via the limiting cylinder 4. Meanwhile, a sampling tube 1 is rotatably connected inside the limiting cylinder 4, and an inlet 14 is provided on the side wall of the sampling tube 1. This allows the sampling tube 1 to penetrate the inside of the receiving plate 5 and enter the oil tank to sample the oil through the inlet 14 during use. This reduces the volatilization of the mixture of inert gas and oil vapor in the oil tank and avoids affecting the oil tank. In addition, the inlet 14 on the side wall of the sampling tube 1 makes it easy to enter the oil tank and sample directly, avoiding the problem of difficulty in sampling the oil at the bottom of the oil tank when extracting oil.
