[0001] The present application relates to the field of reaction vessels, in particular to a thermometer nozzle structure that can adapt to different process measurement point requirements.

[0002] A reaction vessel refers to a vessel used to complete the physical reaction and chemical reaction of a medium. In industrial production, especially in the chemical, pharmaceutical, fertilizer, and refining industries, reaction vessels are widely used as pressure-bearing equipment due to process requirements.

[0003] In order to measure the temperature inside the reaction vessel, a thermometer nozzle needs to be provided on the reaction vessel. The temperature of some media inside the reaction vessel can reach several hundred degrees. Therefore, a sleeve is provided outside the thermometer to protect the thermometer. Please refer to the prior art (ZL202021413882.1), which discloses a detachable thermometer nozzle structure, including a connecting flange, a connecting pipe flange, a thermometer sleeve, and a cap. The defect of this kind of thermometer nozzle structure is that the insertion depth of the thermometer cannot be adjusted after it is inserted into the thermometer sleeve, so it cannot adapt to different process measurement point requirements.
