Description

Technical Field

[0001] This utility model relates to the field of instrument manufacturing, and in particular to an improved level gauge for radioactive media. Background Technology

[0002] An improved level gauge for radioactive media solves the problems of measurement failure and equipment damage of traditional level gauges in radioactive environments. By optimizing the accuracy of X-ray detection and radiation-resistant design, it achieves safe and accurate monitoring of the level of radioactive media, ensuring production safety in high-risk scenarios such as nuclear energy and chemical industry, and reducing maintenance costs and personnel radiation exposure risks.

[0003] The liquid level gauge utilizes the fact that the intensity of the rays emitted by a radioactive isotope decreases as the thickness of the medium changes. The ray source and detector are installed on both sides of the container. When the liquid level rises or falls, the intensity of the rays received by the detector changes. The signal processing circuit converts the intensity change into an electrical signal, which is then converted into the liquid level height through a calibration algorithm.

[0004] In existing technologies, some level gauges do not have easily disassembled components during installation and later replacement. This inconvenience in installation and replacement leads to extended construction periods and increased costs. Difficulty in later replacement increases maintenance time and long-term equipment downtime, resulting in economic losses. Therefore, an improved level gauge specifically for radioactive media is proposed to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The sealing assembly includes a pressure-sensing tube, one end of which is fixedly connected to the outer wall of the range adjustment module. A connecting ring is fixedly connected to one end of the pressure-sensing tube. Two fixing blocks are fixedly connected to the outer wall of the connecting ring.

A pressure ring is fixedly connected to the outer wall of the connecting rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the connecting ring is rotatably connected to a quick connector, and the outer wall of the quick connector is provided with a sliding groove.

[0012] As a further description of the above technical solution:

[0013] A limit block is fixedly connected to the outer wall of the quick connector, and a rotating block is fixedly connected to the outer wall of the quick connector;

[0014] As a further description of the above technical solution:

[0015] A capillary tube is fixedly connected to the inner wall of the rotating block, and a flange diaphragm is fixedly connected to one end of the capillary tube.

[0016] As a further description of the above technical solution:

[0017] A fixing ring is fixedly connected to the bottom of the limiting ring, and a display module is fixedly connected to the top of the range adjustment module;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the pressure plate is tightened by the movement of bolts.

This prevents the construction cycle from being extended and costs from being increased due to inconvenient installation and replacement, and prevents the economic losses caused by long-term equipment downtime due to the difficulty of later replacement and increased maintenance time.

[0024] 2. In this utility model, by using the pressure ring to press the surface of the quick connector, after the pressure ring is tightened, one end of the quick connector is fixed to one side of the sealing ring, so that the sealing ring is pressed between the quick connector and the pressure tube, thus completing the seal. This prevents the increase of downtime and the reduction of production efficiency due to insufficient sealing, and also avoids material waste caused by the loss of medium and extends the service life of the equipment.

[0034] Reference Figures 3 to 4 The sealing assembly includes a pressure-sensing tube 12, which is used to transmit signals. One end of the pressure-sensing tube 12 is fixedly connected to the outer wall of the range adjustment module 2. A connecting ring 13 is fixedly connected to one end of the pressure-sensing tube 12. The connecting ring 13 is used to connect the seal. Two fixing blocks 14 are fixedly connected to the outer wall of the connecting ring 13. The fixing blocks 14 are used to fix the round rod 15. The inner walls of the two fixing blocks 14 are fixedly connected to the round rod 15. The round rod 15 is used to provide a movement trajectory for the connecting rod 16. The outer wall of the round rod 15 is rotatably connected to the connecting rod 16. The connecting rod 16 is used to drive the pressure ring 17. The outer wall of the connecting rod 16 is fixedly connected to the pressure ring 17. The pressure ring 17 is used to press the quick connector 18. The inner wall of the connecting ring 13 is rotatably connected to the quick connector 18. The quick connector 18 is used to press the sealing ring 11. The outer wall of the quick connector 18 has a sliding groove 19, which is used to facilitate the installation of the quick connector 18. A limit block 20 is fixedly connected to the outer wall of the quick connector 18. The limit block 20 is used to prevent excessive pressure from damaging the sealing ring 11. A rotating block 21 is fixedly connected to the outer wall of the quick connector 18. The rotating block 21 is used to rotate the quick connector 18.

[0035] Working principle: When installing a level gauge for easy replacement later, first slowly lower the capillary tube 22 into the liquid. The flange diaphragm 23 fixed to one end of the capillary tube 22 will also slowly contact the liquid surface. When it reaches the designated position, insert the fixing rod 4 into the inner wall of the nut 9. Then rotate the bolt 10. The rotation of the bolt 10 presses the pressure plate 5, causing it to tighten inwards. The fixing rod 4 is then fixed in place. When replacement is needed, pull the capillary tube 22 upwards. The flange diaphragm 23 fixed to one end of the capillary tube 22 will also be pulled away from the liquid surface. Then rotate the bolt 10. The rotation of the bolt 10 loosens the pressure on the pressure plate 5, causing it to loosen to both sides. The fixing rod 4 can then be pulled out for replacement. This avoids extending the construction period and increasing labor and time costs.

[0036] When a good seal is required for the level gauge, fix the connecting ring 13 to one end of the pressure inlet tube 12. Then lift the connecting rod 16, and the pressure ring 17 will also be lifted. Insert the slide groove 19 of the quick connector 18 along the pressure ring 17. Then rotate the quick connector 18. When the limiting block 20 is parallel to the connecting rod 16, reset the connecting rod 16. The pressure ring 17 will then contact the surface of the quick connector 18. At this time, the bottom of the quick connector 18 will press on the sealing ring 11, and the seal of the level gauge will be completed, thus avoiding the risk of leakage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
