Abstract

The invention discloses a heat-resistant explosion-proof temperature thermocouple structure which comprises a shell assembly, a connecting wire, a thermocouple wire and a fixing agent. A supporting assembly comprises supporting rods, jacking columns and a first spring. A plurality of jacking columns are fixedly connected with the support rods; the shell assembly comprises a sliding rod, locking pieces and a protective sleeve. The sliding rod is slidably connected with the supporting rod; a plurality of locking pieces are rotationally connected with the sliding rod and close to the jacking columns, the first spring is mounted between the sliding rod and the supporting rod; when the sliding rod is impacted by high pressure, the first spring contracts to absorb impact, the jacking columns contact with the locking pieces so that the locking pieces are opened to contact with the wall of the to-be-detected container to prevent the sliding rod from continuously moving outwards; the protectivesleeve is fixedly connected with the sliding rod, the thermocouple wire is located in the protective sleeve, the connecting wire penetrates through the supporting rod, the sliding rod and the protective sleeve and is electrically connected with the thermocouple wire, and the protective sleeve is filled with a high-temperature-resistant fixing agent so that the thermocouple can work normally in ahigh-temperature and high-pressure environment.

Description

technical field [0001] The invention relates to the field of thermocouples, in particular to a heat-resistant and explosion-proof temperature-measuring thermocouple structure. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). [0003] In the chemical industry, with the development of science and technology, the control of the manufacturing process is becoming more and more refined, and it is necessary to continuously measure the temperature and other parameters in the manufacturing process. However, the chemical production process is often accompanied by various flammable Explosive chemical gases, high-temperature environment and severe impact can easily damage therm...
