Description

Technical Field

[0001] This utility model relates to the field of detection and sampling technology, specifically a Milliphone interface device for a closed-circuit sampler that facilitates water testing. Background Technology

[0002] In aviation fuel refueling operations, accurate detection of water content in fuel is crucial, as it directly relates to flight safety. The core function of the closed-circuit sampler with a Millimeter interface device, which facilitates water detection, is to solve various problems existing in the traditional Millimeter interface when detecting water in fuel, ensuring that the water detection process is efficient, safe, and the test results are accurate and reliable.

[0003] The device mainly consists of an interface body, adapter components, a dust cover, and a connection structure. The interface body adopts a special design and achieves a tight connection with various water sampler syringes through a precise internal structure. The adapter components can be finely adjusted according to different models of water sampler syringes to ensure compatibility. The dust cover is made of plexiglass, which not only allows for direct observation of the interface cleanliness but also provides excellent sealing performance, effectively preventing dust and rainwater intrusion. The connection structure is designed with two different mounting thread hole diameters, facilitating installation on different models of closed-circuit samplers.

[0004] However, in actual use, most of the standard closed-circuit samplers mentioned above only have interfaces that are compatible with the syringes that came with early imported water testers, and are not compatible with various new models of syringes. In addition, since oil samples can only be obtained from the top of the closed-circuit sampler, the accuracy of oil testing is questionable, and the results can no longer fully represent the overall oil quality. In view of this, we propose a Millibo interface device for closed-circuit samplers that is convenient for water testing. Utility Model Content

[0034] In one embodiment of this utility model, a sampling component 5 is provided on the circular plate 4. The sampling component 5 includes a glass tube 51. One end of the glass tube 51 is snapped onto the circular plate 4, and a cover 52 is snapped onto the other end of the glass tube 51. A funnel groove 53 and an inclined groove 54 are provided on the circular plate 4. One end of a connecting pipe 55 is fixedly installed at the bottom of the circular plate 4. One end of a three-way pipe 56 is fixedly installed on the circular plate 4. A snap-fit ​​connector 57 is fixedly installed at the other end of the three-way pipe 56. One end of a closed-loop pipe 58 is snapped onto the snap-fit ​​connector 57. A connector 59 is fixedly installed on the three-way pipe 56. A threaded cylinder 510 is fixedly installed on the connector 59. A nut 511 is fixedly installed on the connector 59. A fastening knob 512 is threaded onto the nut 511. A first-order long bracket 513 is threaded onto the threaded cylinder 510. A sampling syringe 514 is snapped onto the upper part of the 13. An adjustment switch 517 is provided on the circular plate 4. A second short bracket 515 is threaded onto the threaded cylinder 510 as a replacement for the first long bracket 513. A second sampling syringe 516 is snapped onto the second short bracket 515. Rubber rings 61 are fixedly installed on the first long bracket 513 and the second short bracket 515. Dust covers 62 are snapped onto the first long bracket 513 and the second short bracket 515. A scale mark 63 is fixedly installed on the glass cylinder 51. Nuts 511 and fastening knobs 512 are located above the first sampling syringe 514 and the second sampling syringe 516. The bottom of the funnel groove 53 is connected to the connecting pipe 55. The inclined groove 54 is connected to the three-way pipe 56, the clamping connector 57, and the closed-loop pipe 58. The other end of the connecting pipe 55 is connected to the other end of the closed-loop pipe 58 and the circulating pump.

[0035] In this embodiment, before using the device, firstly, the entire device is fixed in a suitable position using the support plate 1. The support plate 1 provides a stable support foundation for the device. The square plate 2 is fixed on the support plate 1, and the right-angle bracket 3 is fixed to the square plate 2, thereby supporting the circular plate 4 and ensuring that the circular plate 4 is stably installed. For the sampling component 5, if the first sampling syringe 514 is to be used, the first long bracket 513 is threaded onto the threaded cylinder 510. The rubber ring 61 on the first long bracket 513 is tightly fitted to the first sampling syringe 514 to enhance the connection stability. Then, the first sampling syringe 514 is snapped onto the first long bracket 513. If the second sampling syringe 516 is to be used, the first long bracket 513 is replaced with the second short bracket 515, similarly using the rubber ring 61. 1. Securely connect the second sampling syringe 516. Simultaneously, ensure the dust cover 62 is securely fastened to the first long bracket 513 or the second short bracket 515 to prevent dust from entering the sampling syringe and affecting the test results. After preparation, begin the sampling operation. Open the cap 52 and inject the oil sample through the funnel groove 53. The bottom of the funnel groove 53 is connected to the connecting pipe 55, allowing the oil sample to flow smoothly into the glass cylinder 51. The glass cylinder 51 holds the oil sample, and its graduation markings 63 allow the operator to visually observe the oil sample volume and easily control the injection volume. When it is necessary to obtain an oil sample from another location, control the adjusting switch 517 to allow the oil sample to enter through the inclined groove 54. The inclined groove 54 is connected to the three-way pipe 56, the clamp connector 57, and the closed-loop pipe 58. The oil sample flows through this closed pipeline system. The tee pipe 56 plays a crucial role in connecting different components, ensuring smooth sample transfer. The clamp connector 57 and the closed-loop pipe 58 guarantee a closed environment for the oil sample during transfer, preventing contamination from external impurities and ensuring accurate test results. After sampling, close the cap 52 and adjust the device to the testing state. If using sampling syringe 514 (No. 1) or sampling syringe 516 (No. 2) for water testing, first loosen the fastening knob 512. Adjust the position of the sampling syringe using the long bracket 513 (No. 1) or short bracket 515 (No. 2) so that the needle is aligned with the oil sample inside the glass tube 51. Then, rotate the fastening knob 512 and use the nut 511 to fix the sampling syringe in the appropriate position, ensuring accurate sampling. The sample syringe is stable, facilitating accurate oil sample extraction for testing. After testing, the cap 52 is opened again, and the oil sample discharge is controlled by the adjustment switch 517. The oil sample can be discharged through the connecting pipe 55 or the inclined groove 54, the three-way pipe 56, the clamp connector 57, and the closed-loop pipe 58. The other end of the connecting pipe 55 is connected to the other end of the closed-loop pipe 58, which is connected to the circulation pump for convenient subsequent processing of the oil sample. After processing the oil sample, the sampling syringe is removed from the bracket for cleaning or replacement. At the same time, check whether there is dust accumulation on the dust cover 62. If so, it needs to be cleaned or replaced to ensure the cleanliness of the device for the next use. If residual impurities or blurred scale markings 63 are found in the glass cylinder 51, it needs to be cleaned or replaced to ensure that the device is always in good working condition.

[0036] In one embodiment of this utility model, an auxiliary component 7 is provided on the circular plate 4. The auxiliary component 7 includes a lower mounting block 71. The lower mounting block 71 is fixedly mounted on the circular plate 4. A ring 73 is fixedly mounted on the glass tube 51. An upper mounting block 74 is fixedly mounted on the ring 73. One end of a reinforcing rod 72 is rotatably mounted on the upper mounting block 74. Multiple sets of lower mounting blocks 71, reinforcing rods 72 and upper mounting blocks 74 are provided. The other end of the reinforcing rod 72 is threaded and threaded onto the lower mounting block 71.

[0037] In this embodiment, when installing the glass cylinder 51, one end of the reinforcing rod 72 is rotatably mounted on the upper mounting block 74, and the other end is threaded onto the lower mounting block 71. By rotating the reinforcing rod 72, its length is adjusted to ensure a tight connection between the glass cylinder 51 and the circular plate 4, thus ensuring the stability of the glass cylinder 51 during subsequent use. During the testing process, the auxiliary component 7 continues to function, with the reinforcing rod 72 tightly connecting the glass cylinder 51 and the circular plate 4 to prevent the glass cylinder 51 from shaking or shifting. Even in environments with vibration or external interference, the reinforcing rod 72 can effectively reduce the impact on the glass cylinder 51, preventing oil sample spillage or affecting testing accuracy due to the shaking of the glass cylinder 51, ensuring a stable testing process, and improving the reliability of the test results.
