Description

Technical Field

[0001] This utility model relates to the field of thermocouples, and more specifically, to a high-temperature thermocouple with a wear-resistant mechanism. Background Technology

[0002] The primary function of a high-temperature thermocouple is to measure temperature in high-temperature environments. It operates based on the thermoelectric effect, forming a closed circuit between two different metal conductors. When a temperature gradient exists within the circuit, a thermoelectric electromotive force is generated, thereby measuring the temperature. It is suitable for temperature measurement in high-temperature and corrosive environments, ensuring control and quality in production processes.

[0003] However, most high-temperature thermocouples currently have the following problems:

[0004] I. Existing high-temperature thermocouples have poor wear resistance. In harsh working environments, their outer protective sleeves are easily worn, which may even lead to leakage of internal heat-conducting materials, seriously affecting testing and making wear protection inconvenient.

[0005] Second, most existing high-temperature thermocouples have their outer tubes fixed or connected to the equipment with multiple bolts. When the equipment is exposed to high temperatures for a long time, it is prone to slight deformation, which affects the subsequent use effect and makes it inconvenient to install or disassemble the outer tube.

[0006] Therefore, we have made improvements and proposed a high-temperature thermocouple with a wear-resistant mechanism. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in providing wear-resistant protection and inconvenience in installing and disassembling the outer tube.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The application is as follows:

[0011] The device includes an insulating tube and a positive electrode of a thermocouple wire.

[0012] As a preferred technical solution of this application, the insulating tube, the inner sleeve, and the bottom of the thermocouple are arc-shaped, and the bottom of the inner sleeve, the thermocouple, and the wear-resistant sleeve are provided with through holes.

[0013] As a preferred technical solution of this application, the wear-resistant sleeve includes a fixing tube, a reinforcing rib is fixedly connected to the fixing tube, and a wear-resistant layer is fixedly connected to the reinforcing rib.

[0015] As a preferred technical solution of this application, a locking block is fixedly connected to the limiting plate, and a pull rod is fixedly connected to the limiting plate, wherein the length of the locking block is less than the length of the pull rod.

[0016] As a preferred technical solution of this application, the mounting boxes are symmetrically distributed on the left and right sides of the threaded connection sleeve, and the mounting boxes correspond one-to-one with the locking blocks through the limiting plates.

[0018] In the scheme of this application:

[0019] 1.

[0035] like Figure 1-7 As shown, this embodiment proposes a high-temperature thermocouple with a wear-resistant mechanism, including an insulating tube 1 and a thermocouple wire positive electrode 2. The thermocouple wire positive electrode 2 is installed on the insulating tube 1, and the thermocouple wire negative electrode 3 is installed on the insulating tube 1. A terminal block 4 is installed on the thermocouple wire positive electrode 2 and the thermocouple wire negative electrode 3. A wire outlet 5 is fixedly connected to the terminal block 4. An inner sleeve 6 is provided on the insulating tube 1, and a thermocouple 7 is provided on the inner sleeve 6. A wear-resistant sleeve 8 is provided on the thermocouple 7. A threaded connecting sleeve 9 is fixedly connected to the wear-resistant sleeve 8. A mounting box 10 is fixedly connected to the threaded connecting sleeve 9. A spring 11 is fixedly connected inside the mounting box 10, and a limit plate 12 is fixedly connected to the other end of the spring 11.

[0036] Example 2:

[0037] The solution in Example 1 will be further described below with reference to its specific working method.

[0038] like Figure 2 As shown, in a preferred embodiment, based on the above method, the bottom of the insulating tube 1, the inner sleeve 6, and the thermocouple 7 are arc-shaped, and the bottom of the inner sleeve 6, the thermocouple 7, and the wear-resistant sleeve 8 are provided with through holes, which can ensure that the positive electrode 2 and the negative electrode 3 of the installed thermocouple wire can pass through the through holes on the inner sleeve 6, the thermocouple 7, and the wear-resistant sleeve 8.

[0039] like Figure 5 As shown, in a preferred embodiment, based on the above method, the wear-resistant sleeve 8 further includes a fixing tube 801, a reinforcing rib 802 fixedly connected to the fixing tube 801, and a wear-resistant layer 803 fixedly connected to the reinforcing rib 802, which can ensure that the installed wear-resistant sleeve 8 can play a wear-resistant protection role.

[0040] like Figure 6As shown, in a preferred embodiment, based on the above method, the cross-section of the reinforcing rib 802 is an interlaced triangle, and the side end face of the limiting plate 12 is in contact with the inner side of the mounting box 10, which can ensure that the connected reinforcing rib 802 can play a role in strengthening protection.

[0041] like Figure 3 As shown, in a preferred embodiment, based on the above method, a locking block 13 is fixedly connected to the limiting plate 12, and a pull rod 14 is fixedly connected to the limiting plate 12. The length of the locking block 13 is less than the length of the pull rod 14, which can ensure that the locking block 13 can be retracted into the mounting box 10 when the pull rod 14 is pulled.

[0042] like Figure 3 As shown, in a preferred embodiment, based on the above method, the mounting box 10 is symmetrically distributed on the left and right sides of the threaded connecting sleeve 9. The mounting box 10 corresponds one-to-one with the locking block 13 through the limiting plate 12, which can ensure that the locking blocks 13 on both sides can be locked in the thermocouple 7 and the wear-resistant sleeve 8 for limiting and fixing.

[0043] Specifically, when using a high-temperature thermocouple with a wear-resistant mechanism: [the following is a continuation of the previous sentence, likely due to an error in the original text] Figure 1-7 When using the equipment, the wear-resistant sleeve 8 on the outer layer can improve the wear resistance strength, and the fixing tube 801 is attached and fixed to the thermocouple 7. The reinforcing rib 802 installed in the middle can improve the wear resistance strength of the wear-resistant sleeve 8, and the wear-resistant layer 803 on the outer layer can improve the wear resistance effect and avoid wear affecting subsequent use.

[0044] When disassembling the wear-resistant sleeve 8 and the threaded connection sleeve 9, the pull rod 14 on both sides of the mounting box 10 can be pulled to move the limiting plate 12. The limiting plate 12 can squeeze the spring 11. At the same time, the limiting plate 12 can drive the locking block 13 to disengage from the thermocouple 7 and the wear-resistant sleeve 8 and return to the mounting box 10. After being unobstructed, the wear-resistant sleeve 8 and the threaded connection sleeve 9 on the thermocouple 7 can be disassembled. When fixing the wear-resistant sleeve 8, the pull rod 14 is released and the limiting plate 12 and the locking block 13 are reset under the push of the spring 11. The locking block 13 can be locked on the thermocouple 7 to fix the wear-resistant sleeve 8 and the threaded connection sleeve 9. The installed threaded connection sleeve 9 can be threaded to the position of use. The wire outlet 5 on the terminal block 4 can be connected to the positive electrode 2 and the negative electrode 3 of the thermocouple wire for subsequent use. The insulating tube 1 inside the inner sleeve 6 can play the role of insulation protection.
