る。A small hole 7 is bored in the tube wall of the object to be measured 1 such as a heat receiving tube, a thermocouple source 2 including the end of the thermocouple is inserted, and the thermocouple portion extending from this extends in the longitudinal direction of the tube and a sheath cover 3 is inserted. It is covered and pulled out of the device. Inside this sheath cover 3, if necessary, there is a device to pass cooling air etc. to prevent burnout due to high temperature gas etc.
1 | When installing the thermocouple source 2 by extension, cut grooves in an arc shape in the circumferential direction of the pipe wall as shown in Figure 2.
and cover it with arc-shaped thin plate 3, welding part 3A.
Attach this to the pipe wall by welding. However, during this welding operation, the sheath may be overheated, and depending on the material of the pipe, there may be an opportunity for cracks to occur if the pipe is left welded, which is undesirable. Furthermore, the installation work of thermocouples also requires time and effort. It is an object of the present invention to eliminate such drawbacks and to propose a thermocouple fixing means that does not affect the quality of the pipe material and is easy to install.

り説明する。In short, this invention is characterized in that a welded protrusion of a certain length is provided on the surface of the object to be measured, a cut groove is provided in the longitudinal direction, and the thermocouple source is inserted into the protrusion and then fixed by caulking. do. This invention will be explained with reference to FIGS. 4 to 6.

ものである。In FIG. 4, a protrusion 5 is formed on the half circumference of the outer surface of the pipe IA by welding. Then, a groove 8 is formed approximately in the center of the protrusion using a cylinder cutter or the like, so that the depth of the groove reaches a part of the tube wall thickness. Then, the end of the thermocouple source 2 is inserted into the hole 7 made in the tube wall, and then, as shown in FIG. Hold. Next, the sheath cover 3 is attached by welding in the same manner as in FIG. FIG. 7 shows another embodiment of the present invention in which a thermocouple sheath is attached to the fin portion 9. FIG. 8 shows a case where a groove 8 is machined in the fin portion of a finned tube and a thermocouple sheath 2 is embedded and attached thereto. By carrying out this invention, there is no damage to the thermocouple sheath due to heat during the installation and welding work of the cover 31 as shown in FIG.
The formation of protrusions and processing of grooves can be done in advance at the factory, making it easy to install the thermocut pull sheath on site.
This provides various effects such as accurate display of tube wall temperature.
