Description

Technical Field

[0001] This invention relates to the field of nuclear energy engineering technology, and in particular to a conductivity probe device and a system for measuring local parameters of liquid metal two-phase flow. Background Technology

[0002] Currently, there are many methods for measuring two-phase flow of gas in water. However, due to the high temperature, corrosiveness, and opacity of liquid metals, most traditional gas-water two-phase flow measurement methods are not applicable to the measurement of high-temperature liquid metal gas-liquid two-phase flow. The technologies for measuring liquid metal two-phase flow currently available in the literature are mainly neutron imaging and conductivity probes. Neutron imaging technology has insufficient spatial resolution, making it difficult to measure interfacial area concentration, and its high cost limits its widespread application in industrial production and scientific research. Therefore, at present, conductivity probe measurement systems are mostly used, offering advantages such as fast response speed, high measurement accuracy, and low manufacturing cost.

[0003] Because conductivity probes are invasive, meaning the measuring end of the probe extends into the test section (test pipe), and because liquid metal two-phase flow experiments are not visual, the exact location of the measuring end of the conductivity probe within the test section cannot be seen from the outside. To collect multiple sets of data, the experiment requires measuring the conductivity probe at multiple locations on the same horizontal cross-section. However, the current common method for adjusting the conductivity probe position is to manually adjust the measurement point before testing by manually pulling the end of the conductivity probe outside the test section horizontally. Therefore, the accuracy of existing conductivity probe adjustment methods is limited, easily leading to errors in experimental measurement parameters.

[0004] Therefore, the existing technology still needs to be improved and enhanced. Summary of the Invention

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In gas-liquid two-phase flow testing experiments, the common method for adjusting the position of the conductivity probe is to manually adjust the measurement point before the test. This is done by manually pulling the end of the conductivity probe located outside the test section horizontally, thus moving the measuring end of the conductivity probe located in the test section. This adjustment method has limited accuracy and is prone to errors in the experimental measurement parameters. Therefore, the present invention provides the following embodiments to solve the above-mentioned technical problems.

[0021] Example 1: Please see Figures 1-3 The conductivity probe device includes: a base 1; a lead screw 2 rotatably mounted on the base 1; a motor 3 mounted on the base 1 and connected to one end of the lead screw 2 for driving the lead screw 2 to rotate; a slide 4 through which the lead screw 2 passes and is threadedly connected to the slide 4 to drive the slide 4 to slide; and a conductivity probe 5 mounted on the slide 4 to move with the slide 4.

[0022] like Figure 1 As shown, in this embodiment, the conductivity probe device includes a base 1, a lead screw 2, a motor 3, a slide 4, and a conductivity probe 5. The base 1 is rectangular in shape. The lead screw 2 is located above the slide rail 101 and is rotatably mounted on the base 1. The motor 3 is located at the left end of the base 1, and its shaft is connected to the lead screw 2 to drive the lead screw 2 to rotate. The slide 4 is slidably mounted on the base 1. The lead screw 2 passes through the slide 4 and is threadedly connected to it. When the lead screw 2 rotates, it drives the slide 4 to slide on the base 1. The left end of the conductivity probe 5 is fixedly connected to the slide 4, and the conductivity probe 5 is horizontally mounted on the slide 4. When the slide 4 slides along the lead screw 2, it drives the conductivity probe 5 to move laterally left and right along the horizontal plane. After moving laterally left and right along the horizontal plane, the conductivity probe 5 will measure multiple points on the same horizontal cross-section in the test section. In this embodiment, the motor 3 drives the lead screw 2 to slide the slide block 4. During the sliding process, the slide block 4 will move the conductivity probe 5. Controlling the movement distance of the conductivity probe 5 through the motor 3, lead screw 2, and slide block 4 is more precise than manual adjustment, thereby reducing the error of experimental measurement parameters. At the same time, a scale is also provided on the side of the slide rail 101 along its length to facilitate direct observation of the movement distance of the conductivity probe 5.

[0023] As a further embodiment, the conductivity probe device also includes a first tensioning component 6, the connecting end of the first tensioning component 6 being detachably connected to the slide 4, the conductivity probe 5 passing through the first tensioning component 6 and the slide 4, and the adjusting end of the first tensioning component 6 being used to clamp or loosen the conductivity probe 5 assembly. Specifically, the right end of the first tensioning component 6 is threadedly connected to the slide block 4, that is, the slide block 4 has a threaded hole, and the right end of the first tensioning component 6 has an external thread. The first tensioning component 6 is threadedly connected to the threaded hole of the slide block 4 through the external thread, so as to facilitate the disassembly or assembly of the first tensioning component 6 and the slide block 4. The conductivity probe 5 passes through the first tensioning component 6 and the slide block 4, and the left end of the first tensioning component 6 can clamp or loosen the conductivity probe 5, so that the conductivity probe 5 is detachable, and the conductivity probe 5 can be angled before the experiment. In this embodiment, the right end of the conductivity probe 5 is L-shaped. The right end of the conductivity probe 5 needs to be kept perpendicular to the horizontal plane before the experiment. Therefore, when adjusting the angle of the conductivity probe 5, the left end of the first tensioning component 6 loosens the conductivity probe 5. After the angle is adjusted, the left end of the first tensioning component 6 clamps and fixes the conductivity probe 5 to prevent it from deviating during the experiment. At this time, the slide block 4 can move the conductivity probe 5 together through the first tensioning component 6.

[0024] like Figure 2 and Figure 3 As shown, as a further embodiment, the first tensioning assembly 6 includes a sleeve 601, an adjusting nut 602, a washer 603, and a tensioning ring 604. One end of the sleeve 601 is threaded to the slide block 4, and the other end of the sleeve 601 has an axially tapered hole 6011. One end of the adjusting nut 602 is threaded to the other end of the sleeve 601. The washer 603 is disposed inside the adjusting nut 602, and one end abuts against the inner end face of the adjusting nut 602. The tensioning ring 601... 4 is frustum-shaped and disposed within the conical hole 6011, with the larger end of the tension ring 604 abutting against the other end of the gasket 603; the conductivity probe 5 sequentially passes through the adjusting nut 602, gasket 603, tension ring 604 and sleeve 601, with the smaller end of the tension ring 604 fitting against the outer side of the conductivity probe 5, and the adjusting nut 602 used to push the gasket 603 and the tension ring 604 so that the smaller end of the tension ring 604 clamps the conductivity probe 5.

[0025] Specifically, the sleeve 601 has external threads at both ends, one end of which is used for threaded connection with the slide block 4. The sleeve 601 also has a hexagonal connector on its outer side for easy tightening with a wrench. The adjusting nut 602 is threaded to the other end of the sleeve 601. The sleeve 601 has a tapered hole 6011 at the end facing the adjusting nut 602, with the opening of the tapered hole 6011 closer to the adjusting nut 602 being larger than the opening at the end further away from the adjusting nut 602. A washer 603 is disposed inside the adjusting nut 602, with one end of the washer 603 abutting against the inner end face of the adjusting nut 602. The tightening / loosening... The ring 604 is frustum-shaped, and the slope of the tension ring 604 is the same as the slope of the conical hole 6011. The smaller end of the tension ring 604 is located inside the conical hole 6011, and the larger end of the tension ring 604 abuts against the other end of the washer 603. When the adjusting nut 602 is rotated clockwise to move towards the sleeve 601, the end face inside the adjusting nut 602 pushes the washer 603 and the tension ring 604 to move. At this time, the tension ring 604 is squeezed by the conical hole 6011 and slightly deformed. The smaller end of the tension ring 604 converges inward and clamps the conductivity probe 5, thereby fixing the conductivity probe 5. When the adjusting nut 602 is reversed and moves away from the sleeve 601, the tensioning ring 604 is no longer compressed and returns to its original shape. At this time, the tensioning ring 604 releases the conductivity probe 5, and the conductivity probe 5 can be detached or its angle can be adjusted.

[0026] In this embodiment, the conductivity probe device further includes a first support plate 7 and a second support plate 8. A slide rail 101 is provided on the base 1, and the slide block 4 is slidably connected to the slide rail 101. The first support plate 7 is disposed on the base 1 and close to one end of the slide rail 101. The motor 3 is disposed on one side of the first support plate 7, and one end of the lead screw 2 passes through the first support plate 7 and is connected to the motor 3. The second support plate 8 is disposed on the base 1 and close to the other end of the slide rail 101, and is opposite to the first support plate 7. The other end of the lead screw 2 is rotatably connected to the second support plate 8. Specifically, a slide rail 101 distributed along the length of the base 1 is provided on the top side of the base 1. The bottom side of the slide block 4 is clamped on the slide rail 101 and can slide on the slide rail 101. A rotating hole or bearing can be provided on the second support plate 8, allowing the other end of the lead screw to be rotatably connected to the rotating hole or bearing. The first support plate 7 and the second support plate 8 can limit the movement of the slide block 4.

[0027] As a further embodiment, the slide block 4 includes a slider 401 and a support base 402. The slider 401 is slidably mounted on the slide rail 101; the support base 402 is mounted on the slider 401, and one end of the sleeve 601 is threadedly connected to the support base 402. The conductivity probe 5 passes through the support base 402. Specifically, the support base 402 supports the conductivity probe 5, one end of the conductivity probe 5 passes through the sleeve 601 and the support base 402, and the support base 402 is detachably connected to the slider 401 by screws.

[0028] As a further embodiment, the conductivity probe device also includes a connecting plate 9 and a sealing insert 10. The connecting plate 9 is disposed at one end of the base 1; the sealing insert 10 is disposed on the side of the connecting plate 9 opposite to the slide 4, and the conductivity probe 5 passes through the connecting plate 9 and the sealing insert 10. Specifically, the connecting plate 9 and the sealing insert 10 are respectively provided with through holes for the conductivity probe 5 to pass through, and the sealing insert 10 is used to connect to the test section 12 and seal the connection point with the test section 12, thereby preventing liquid metal from flowing out of the test section 12.

[0029] In this embodiment, the conductivity probe device further includes a second tensioning component 11. The connecting end of the second tensioning component 11 passes through the connecting plate 9 and is detachably connected to the sealing insert 10. The conductivity probe 5 passes through the second tensioning component 11 and the sealing insert 10. The adjusting end of the second tensioning component 11 is used to clamp or loosen the conductivity probe 5 assembly.

[0030] Specifically, the structure of the second tensioning component is the same as that of the first tensioning component. One end of the sleeve in the second tensioning component passes through the connecting plate 9 and is threadedly connected to the sealing insert 10 to enhance the sealing effect on the liquid metal in the test section 12. The adjusting nut in the second tensioning component is located at the end of the second tensioning component away from the connecting plate 9, and is also used for adjustment to adjust the tightness of the tensioning ring in the second tensioning component, thereby fixing the conductivity probe 5. In this embodiment, when the conductivity probe 5 is adjusted in the experiment, the second tensioning component needs to be loosened first, and then the motor 3 is started to drive the conductivity probe 5 to move through the cooperation of the lead screw 2 and the slide 4. After the position of the conductivity probe 5 is adjusted, the second tensioning component is tightened.

[0031] Example 2: Please see Figures 4-6This invention also provides a local parameter measurement system for liquid metal two-phase flow, which includes the aforementioned conductivity probe device and a test section 12. A fitting portion 13 is provided on the outer side of the test section 12, and an embedding hole 1301 is provided on the fitting portion 13. The embedding hole 1301 penetrates the sidewall of the test section 12. A sealing block 10, on the side opposite to the connecting plate 9, is disposed within the embedding hole 1301 and is sealed to the fitting portion 13. The measuring end of the conductivity probe 5 penetrates the embedding hole 1301 and extends into the test section 12.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, the embedding hole 1301 is elongated to allow the L-shaped measuring end of the conductivity probe 5 to extend into the test section 12. A sealing ring can also be provided between the sealing insert 10 and the fitting part 13 to enhance the sealing performance between the sealing insert 10 and the fitting part 13.

[0033] like Figure 6 As shown, as a further embodiment, the liquid metal two-phase flow local parameter measurement system further includes a differential pressure measurement component 14. The differential pressure measurement component 14 has a first measuring end 1401 and a second measuring end 1402. The first measuring end 1401 and the second measuring end 1402 are respectively set at different height positions within the test section 12 to form a measurement interval.

[0034] Specifically, in this embodiment, the test section 12 is provided with multiple conductivity probe devices on its side. Each conductivity probe 5 is arranged in a row along the height direction of the test section 12 and spaced apart. In this embodiment, there are three conductivity probes 5, which are arranged vertically in a column along the height direction of the test section 12 with uniform spacing. The highest conductivity probe 5 is aligned with the first measuring end 1401, and the lowest conductivity probe 5 is aligned with the second measuring end 1402. That is, the measurement range of the conductivity probe 5 assembly is consistent with that of the differential pressure measurement assembly 14. The three (or more) conductivity probes 5 evenly arranged along the height direction of the test section 12 can simultaneously collect the local cavitation fraction at different heights on the same vertical line of the test section 12 (such as the upper, middle, and lower parts of the vertical pipe). Compared with the differential pressure measurement assembly 14, which can only obtain the interval average cavitation fraction (overall average), the conductivity probe 5 assembly supplements the local details.

[0035] As a further improvement, the liquid metal two-phase flow local parameter measurement system also includes a gas injection device 15, a gas delivery pipe 16, a high-pressure gas cylinder 17, and a gas valve 18. The gas injection device 15 is located within the test section 12, and its inlet pipe 1501 extends through the test section 12 to the outside. One end of the gas delivery pipe 16 is connected to the inlet pipe 1501, and the high-pressure gas cylinder 17 is connected to the other end of the gas delivery pipe 16. The gas valve 18 is located on the gas delivery pipe 16 to control the gas flow. At the start of the experiment, opening the gas valve 18 allows the high-pressure gas cylinder 17 to inject gas into the gas delivery pipe 16. The gas delivery pipe 16 then transports the internal gas to the test section 12 through the inlet pipe 1501 and the gas injection device 15.

[0036] In this embodiment, the liquid metal two-phase flow local parameter measurement system also includes a central control console 22. The motors 3 in each of the conductivity probe devices are electrically connected to the central control console 22. The central control console 22 is used to control the start or stop of each of the motors 3.

[0037] As a further embodiment, the liquid metal two-phase flow local parameter measurement system further includes a liquid flow meter 20 and a gas flow meter 21. A metal injection pipe 19 is provided on the side of the test section 12. The liquid flow meter 20 is installed inside the metal injection pipe 19 to measure the mass of liquid metal entering the test section 12 per unit time. The gas flow meter 21 is installed in the gas delivery pipe 16 to measure the mass of gas entering the test section 12 per unit time, providing direct basis for calculating relevant parameters of the gas-liquid two-phase flow.

[0038] In summary, this invention provides a conductivity probe device, comprising: a base 1 with a slide rail 101 mounted on it; a lead screw 2 rotatably mounted on the base 1; a motor 3 mounted on the base 1 and connected to one end of the lead screw 2 for driving the lead screw 2 to rotate; a slide block 4 slidably connected to the slide rail 101, with the lead screw 2 passing through the slide block 4 and threadedly connected to it to drive the slide block 4 to slide; and a conductivity probe 5 mounted on the slide block 4 and moved by the slide block 4. In this invention, the motor 3 drives the lead screw 2 to slide the slide block 4, and the sliding of the slide block 4 causes the conductivity probe 5 to move. Controlling the movement distance of the conductivity probe 5 using the motor 3, lead screw 2, and slide block 4 is more precise than manual adjustment, thereby reducing errors in experimental measurement parameters.
