Description

Technical Field

[0001] This invention relates to the field of temperature calibrators, specifically a novel portable high-precision temperature calibration device. Background Technology

[0002] Portable temperature calibrators are widely used in industrial and mining enterprises, power transformers, military industries, metrology departments, etc., and are mainly used to calibrate temperature elements (thermocouples, platinum resistance thermometers, thermometers), temperature transmitters (sensors), temperature switches and temperature instruments. After a period of use, the detection accuracy of portable temperature calibrators is prone to decline due to external factors. Therefore, a new type of portable high-precision temperature calibration device is needed to calibrate them.

[0003] Most existing calibration equipment has limited functionality, using only a single gas or liquid phase for monitoring. This makes it difficult to perform corresponding temperature source detection for inductor components with different sensitivity sources, thus hindering the ability to meet operational requirements. Furthermore, most existing calibration equipment uses a single cavity for monitoring, making it difficult to simultaneously perform temperature detection on multiple detectors at different temperatures. Additionally, existing devices lack leak prevention monitoring for the gas phase during calibration, which can lead to decreased detection performance and create safety hazards in the working environment.

[0035] Please see Figure 7This invention discloses a novel portable high-precision temperature calibration device. The detection mechanism 5 includes a limiting rotating seat 51 installed on the bottom side of the flip cover of the detection box 1 to limit the rotation of a rotating shaft 53. A limiting key 52 is slidably disposed in a groove on the inner side of the limiting rotating seat 51, and the rotating shaft 53 is rotatably disposed within the limiting rotating seat 51, providing a limiting effect for the rotation of the rotating shaft 53.

The inner side of the limit rotating seat 51 is provided with a limit inner groove with an opening angle of 150 degrees, and the adjustment angle of the support frame 54 is 150 degrees, which provides a limit effect for the limit key 52.

[0036] This invention provides a novel portable high-precision temperature verification and calibration device through improvements, the working principle of which is as follows;

[0037] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0038] Secondly, during temperature calibration, the electromagnetic limiting plate 42 provides a fixing effect for the installation of the plug-in plate 41. At the same time, the electromagnetic adsorption effect of the electromagnetic limiting plate 42 allows for the rapid disassembly of the plug-in plate 41, enabling quick disassembly and maintenance of the plug-in plate 41 and the detection mechanism 46. Meanwhile, the plug-in plate 41 provides protection and limiting effect for the detection mechanism 46. When inserting the temperature calibration component, the operator first controls the single-group first reversing valve 44 through the control panel 6 to reduce the air pressure of the single-group sealing airbag 43. At this time, the operator inserts the detection head of the detection component into the sealing airbag 43, and then controls the air pump 45 and the first reversing valve 44 to introduce airflow into the sealing airbag 43. This allows the sealing airbag 43 to seal the inner through hole of the plug-in plate 41 while providing a limiting effect for the detection and calibration component, which helps to improve the limiting effect of the temperature calibration component.

[0039] Third, the heat transfer oil or gas inside the storage tank 4861 is sent into the temperature control box 4862 by controlling the air pump 484 and the liquid pump 485, and heated by the heating wire 4863. Then, the air pump 484 and the liquid pump 485 send the heat transfer oil into the first metering valve 482 for metering and then into the heat transfer oil tank 461. The oil then flows back into the storage tank 4861 through the second metering valve 483. This helps to improve the heating and flow effect of the single-channel heat transfer oil and can also recover the heat used for detection.

[0040] Fourth, at this time, the heat transfer oil enters the heat transfer oil tank 461 through the sealed side plate 463 and is guided by the miniature guide wheel 464, which helps to disrupt the overall flow direction of the liquid or gas, allowing it to flow fully inside the heat transfer oil tank 461. Then, the high-precision thermometer 465 and the single-pass controller 466 provide temperature detection and control for the heat transfer oil. At this time, the temperature data changes of both the high-precision thermometer 465 and the tested component can be observed, and the temperature accuracy of the tested component can be judged and calibrated based on this data, which helps to improve the detection effect of the tested component. At the same time, the limit key 52 slides inside the limit rotating seat 51 to provide a limit effect for the rotation of the rotating shaft 53, and the rotating shaft 53 provides an angle adjustment effect for the thermal imaging detector 56. The thermal imaging detector 56 detects leakage at the sealing airbag 43 on the top side of the plug plate 41, and then the buzzer 55 provides an alarm, which helps to improve the leak prevention detection effect of the tested component.

[0041] This invention provides a novel portable high-precision temperature calibration device through improvements. An electromagnetic limiting plate 42 and a plug-in plate 41 provide protection and limiting effects for the detection mechanism 46. Simultaneously, by controlling the air pump 45 and the first reversing valve 44, airflow is directed into multiple sets of sealing airbags 43. These airbags 43 seal the inner through-holes of the plug-in plate 41 or limit the detection and calibration components, thus improving the limiting effect on the temperature calibration components. Heat transfer oil enters the heat transfer oil tank 461 through the sealing side plate 463 and is guided by the rotation of the miniature guide wheel 464. Then, a high-precision thermometer 465 and a single-pass controller 466 provide temperature detection and control for the heat transfer oil. The flow is further controlled by the flow-guiding air pump 484 and the flow-guiding liquid pump 485. The heat transfer oil inside the storage tank 4861 is sent into the temperature control box 4862 for heating. After being metered by the flow pump 484 and the flow pump 485, the heat transfer oil is sent into the heat transfer oil tank 461 and forms a return flow back to the storage tank 4861. This helps to improve the heating and flow effect of the single-channel heat transfer oil. The limit key 52 slides inside the limit rotating seat 51 to provide a limit effect for the rotation of the rotating shaft 53. At this time, the rotating shaft 53 provides an angle adjustment effect for the thermal imaging detector 56. The thermal imaging detector 56 detects leakage at the sealing airbag 43 on the top side of the plug plate 41 and issues a warning through the buzzer 55, which helps to improve the leakage detection effect of the detection component.
