[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By arranging the flange, mounting hole, temperature dial, lower mounting sleeve, lower limit ring, upper connecting sleeve, upper limit ring, glass tube, lower connecting sleeve, bottom sleeve and probe, a conical bottom sleeve is provided at the bottom to facilitate the insertion of the probe. In addition, the lower connecting sleeve and the bottom sleeve are made of high-strength ceramic, which not only has high hardness, strong corrosion resistance and wear resistance, but also greatly improves the service life of the flange thermometer. The probe can also be completely retracted into the lower connecting sleeve when not in use, which is safer.

[0014] 2. By setting up branches, valves and connectors, the connector can be used to connect to an external air pump. When the air inside the lower connecting sleeve is evacuated, the fluid in the pipeline can enter the lower connecting sleeve, so that the fluid completely wraps the probe, thereby making the temperature measurement more accurate.

The bottom of the glass tube 11 is fixedly connected to a lower connecting sleeve 12, and the bottom of the lower connecting sleeve 12 is fixedly connected to a bottom sleeve 13. The bottom sleeve 13 is conical, and the cone mouth faces downward, which is convenient for the lower connecting sleeve 12 to be inserted into the measuring pipe during installation. The bottom of the flange 1 is fixedly connected to a probe 14, which is located inside the lower mounting sleeve 4, the upper connecting sleeve 6 and the lower connecting sleeve 12.

[0024] The lower connecting sleeve 12 and the bottom sleeve 13 are both made of silicon nitride ceramic. Silicon nitride ceramic is a high-temperature ceramic with high high-temperature strength, high hardness, wear resistance, corrosion resistance and self-lubrication.
