Description

[Technical Field]

[0001] This utility model relates to the field of reaction vessels, and in particular to a thermometer nozzle structure that can adapt to the needs of different process measurement points. [Background Technology]

[0002] A reaction vessel is a container used to carry out physical or chemical reactions in 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] To measure the temperature inside a reaction vessel, a thermometer port needs to be installed on the vessel. In some reaction vessels, the temperature of the medium can reach several hundred degrees Celsius. Therefore, to protect the thermometer, a sleeve is fitted over it. Please refer to the prior art (ZL202021413882.1), which discloses a detachable thermometer port structure, including a connecting flange, a connecting flange, a thermometer sleeve, and a cap. The drawback of this type of thermometer port is that the insertion depth of the thermometer after it is placed inside the thermometer sleeve cannot be adjusted, thus making it unsuitable for different process measurement points.

[0004] Therefore, we need to improve the thermometer tube structure in the existing technology so that the insertion depth of the thermometer can be adjusted after it is inserted into the sleeve. [Utility Model Content]

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a thermometer nozzle structure that can adapt to the needs of different process measurement points.

The top of the inner extension tube is welded to the connecting flange. The flange cover and the connecting flange are connected by a first fixing member. The connecting flange and the connecting flange are connected by a second fixing member. The bottom of the inner extension tube is provided with a threaded adjustment mechanism. The threaded adjustment mechanism includes: a base plate, a sleeve, a sealing plate, a stud, a nut, and a threaded connector. The sleeve is welded to the top of the base plate, and the sealing plate is welded to the top of the sleeve. The sealing plate has a through hole in its center. The lower end of the stud passes through the through hole of the sealing plate and engages with the nut. The upper end of the stud is welded to the threaded connector. The threaded connector has a recessed receiving cavity from top to bottom. The bottom of the inner tube is received in the receiving cavity. The bottom of the inner tube has an external thread. The receiving cavity of the threaded connector has an internal thread that engages with the external thread at the bottom of the inner tube.
