Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model preferred embodiment；
Fig. 2 is another angle schematic diagram of the utility model preferred embodiment；
Fig. 3 is the schematic diagram of the thermometric circle of the utility model preferred embodiment.
Specific embodiment
The utility model will be further described with reference to embodiments.
As shown in Figure 1 and Figure 2, a kind of integral type nuclear power Special temperature measurement suit, including gathering tube 1, fixing pipe 2, thermocouple 3,
Thermometric circle 4, thermocouple intermediate plate 5, support column 6, connection buckle；Gathering tube 1 is fixed on one end outer surface of fixing pipe 2, thermometric circle 4
One end be fixed on the inner surface of fixing pipe 2；The other end of fixing pipe 2 is respectively provided with the other end of thermometric circle 4 and connect
Fixed connection buckle；The circumferentially spaced several thermocouple intermediate plates 5 of arrangement in 4 outer surface of thermometric circle, thermocouple intermediate plate 5 are fixed
It compresses thermocouple 3 and thermocouple 3 is made to be adjacent to 4 surface of thermometric circle；The circumferentially spaced fixation of the inner surface of fixing pipe 2 is several
The other end of dagger 6, support column 6 is supported on tested pipeline.The structure of the utility model guarantee its when being vibrated influence,
Be not in the case where integral support is rotated with tube wall, guarantee the accurate of measurement point.
Connection buckle includes that locking hooks 7, locking button 8, and locking hooks 7 other ends for being mounted on fixing pipe 2,8 installation of locking button
In the other end of thermometric circle 4；When fixed, the button tongue of locking button 8 hooks tight locking and hooks 7.
As shown in figure 3, one end that thermometric circle 4 is fixed on 2 inner surface of fixing pipe is equipped with fixation spring tab 41, thermometric circle 4
The other end is equipped with locking button 8.Convenient for the opening of bracket when fixation spring tab 41 is except installation, elastic slice can also effectively be played vibration
Buffer function.Elastic connection effectively reduces or remits bracket aging caused by pipeline long-term vibration.
As shown in figure 3, the linkage section reflexed on fixation spring tab 41 with 2 inner surface of fixing pipe.Fixation spring tab 41 and fixing pipe 2
Fixed face is more wide, and fixing intensity increases.
Locking button 8 is elasticity locking button, and spring 0~10mm of adjustable range improves tube wall error fault-tolerance.Using bullet
Spring hasp locks link, and spring effectively can play buffer function to vibration.Elastic connection effectively reduces or remits pipeline long-term vibration
Caused bracket aging.
Since thermocouple requires the right half-turn for being distributed in bracket, it must guarantee the right half-turn of bracket thermometric circle as far as possible
