Embodiment Construction
[0014] The specific implementation mode of the present invention is: see figure 1 and figure 2 , including a heat-shrinkable tube and a fixing strip. The heat-shrinkable tube 3 has a long opening 5 in the axial direction. The heat-shrinkable tube 3 is usually made of polymer materials through radiation cross-linking and expansion processes, and has Shape memory, long life and insulation, anti-corrosion effect, split the heat shrinkable tube 3 along the long opening 5, put it on the armored thermocouple 2 on the high pressure cylinder 1 and adjust its position, the heat shrinkable tube 3 is in the opening 5 There may be a seam in the overlapping state, and there may be hot melt glue on the fixing strip 4, and the fixing strip 4 cooperates with the long opening 5 of the heat shrinkable tube 3, so that the heat shrinkable tube 3 becomes a closed whole ; refer to figure 2 , Figure 4 , the inner wall of the heat-shrinkable tube 3 is coated with a hot-melt adhesive layer 6, an...
