In sum; owing to having adopted technique scheme; the utility model has effectively been avoided instrument temperature element to be subject to the temperature element that strong current and gas shock cause damaging; by transition conduit and protective sleeve are installed on temperature element, stress concentration point is transferred on protective sleeve and temperature element machinery rivets tightly a little, and machinery is riveted tightly and can not be damaged temperature element.
Brief description of the drawings
Fig. 1 is the structural representation of the weld seam protection structure of the utility model core level instrument temperature element.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the weld seam protection structure of the utility model core level instrument temperature element, refers to Fig. 1, and a kind of weld seam protection structure of core level instrument temperature element 1, wherein, comprises a temperature element, and on temperature element 1, Laser Welding (LBW) is connected to a transition conduit 2; The two ends of transition conduit 2 are welded on temperature element 1 by laser bonding; the pad at two ends is stress concentration point; on temperature element, be also arranged with one first protective sleeve 31, one second protective sleeve 32; the first protective sleeve 31 is arranged on a side of transition conduit 2 and welds with transition conduit 2, and the second protective sleeve 32 is arranged on the opposite side of transition conduit 2 and welds with transition conduit 2.The first protective sleeve 31 of the present utility model, the second protective sleeve 32 are riveted tightly on temperature element.Employing rivet tightly structure can by stressed be transferred to rivet tightly a little upper, thereby protection temperature element 1.The utility model is as armoured thermocouple and transition conduit 2 laser bonding, and the wall thickness of armoured thermocouple is about armoured thermocouple diameter 1/10, and fusion penetration is about 2/3 of wall thickness, and weld seam is stress concentration point, is subject to be easy to fracture under external impacts.For the intensity of protection weld seam, adopt more protection pipe.
The two ends of transition conduit 2 of the present utility model have two transition conduit 2 hollow round table structures, the outside of transition conduit 2 is all pointed in two less one end of transition conduit 2 hollow round table diameter of movements, temperature element 1 is through the hollow space of hollow round table structure, and the inwall of the lateral wall of temperature element 1 and hollow round table structure hollow part is close to, the first protective sleeve 31, the second protective sleeve 32 are equipped with the cavity of accommodating two transition conduit 2 hollow round table structures near a side of transition conduit 2; Two transition conduit 2 hollow round table structures are placed in the cavity of the first protective sleeve 31, the second protective sleeve 32 separately.
Further, the two ends of transition conduit 2 of the present utility model can have multistage hollow round table structure, from extending laterally near the part of transition conduit 2 inner sides, diameter diminishes step by step, form the frustum cone structure that the multistage diameter of more than one groups constantly diminishes, so that carry out not destroying the original effect of transition conduit after laser bonding.
