Description

Technical Field

[0001] This utility model relates to the field of thermocouple technology, and more specifically, to a novel thermocouple resistant to corrosion in reducing atmospheres. Background Technology

[0002] Thermocouples are commonly used temperature-sensing elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium by an electrical instrument (secondary instrument). The shapes of various thermocouples often differ greatly depending on the application, but their basic structure is roughly the same. They typically consist of thermocouples, insulating sheaths, protective tubes, and junction boxes, and are usually used in conjunction with display instruments, recording instruments, and electronic controllers.

[0003] A search revealed a novel thermocouple resistant to reducing atmosphere corrosion, with publication number CN204649323U. This thermocouple comprises a positive electrode thermocouple lead, a negative electrode thermocouple lead, a junction box and display device, an outer protective tube, and an inner core. Its distinguishing feature is that the outer protective tube has a diameter of 22mm or 20mm, is lined with a 99.2% corundum tube, and contains an inner core with a diameter of 8mm. The solid inner core, due to its compact structure, minimizes the amount of residual air, significantly reducing the selective oxidation of Cr at the positive electrode and thus improving the long-term stability of the thermocouple. The armored core provides vibration resistance, rapid temperature measurement, and a long service life.

[0004] For commonly used thermocouple elements, after installation, their outer shell and base lack protective structures, making them prone to wear and corrosion during use, thus shortening their service life. Therefore, we propose a new type of thermocouple resistant to reducing atmosphere corrosion to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a novel thermocouple resistant to reducing atmosphere corrosion. A protective component is installed on the outside of the cover plate. When assembling the protective plate relative to the cover plate, the positioning post at the bottom of the protective plate is engaged inside the positioning groove, and pressure is continuously applied to the protective plate. The limiting rubber ring on the outside of the positioning post is attached to the surface of the cover plate. The protective plate extends to the outside of the cover plate, providing shielding and protection for the cover plate and the base at the bottom, and has a good sunshade and rainproof effect. A heat insulation gasket is bonded to the inner surface of the protective plate. The heat insulation gasket has good heat insulation performance and reduces the corrosion of the cover plate by external sunlight.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] (1) The protective components are installed on the outside of the cover plate in this solution. When assembling the protective plate relative to the cover plate, the positioning post at the bottom of the protective plate is engaged in the inside of the positioning groove, and pressure is applied to the protective plate. The limiting rubber ring on the outside of the positioning post is attached to the surface of the cover plate. The protective plate extends to the outside of the cover plate and provides shielding and protection for the cover plate and the base at the bottom. It has a good sunshade and rainproof effect. The inner surface of the protective plate is bonded with a heat insulation pad. The heat insulation pad has a good heat insulation performance and reduces the corrosion of the cover plate by external light.

[0021] (2) The reinforcement component of this solution includes a protective ring. The inner surface of the protective ring is fixedly connected to the reinforcement ring through a rubber seat. The protective ring of the reinforcement component is mounted on the outside of the base. The protective ring has a good isolation and protection effect. When a collision occurs, the protective ring squeezes the rubber seat on the surface of the reinforcement ring, and the rubber seat undergoes elastic deformation, which effectively reduces the impact force and is not easily damaged.
