Abstract
The utility model discloses a protective cover for a thermocouple, which relates to the technical field of protective devices for the thermocouple. The utility model comprises a metallic sleeve, wherein the metallic sleeve is sheathed with a plurality of segments of abrasion-resistance sleeves, and an adhesive layer is arranged between the metallic sleeve and the abrasion-resistance sleeves. Compared with the prior art, the utility model has the advantages of good abrasion resistance, long service life and good shock resistance. The utility model can be used for measuring temperature points such as chemical plants, smelting plants, heat-engine plants, etc.
Description
Technical field
The utility model relates to a kind of protective device technical field of thermopair.
Background technology
In industrial robot control system(RCS), thermopair is used widely as temperature sensor, and various wear-resisting type thermocouple protection covers adopt various antifriction alloy integral manufacturings to form usually in the life.At some special occasions; as in measuring point temperature height, the chemical plant that vibration, serious wear are arranged, smeltery, thermal power plant etc.; thermocouple protection overlaps the destruction that very easily is worn; as the point for measuring temperature of locating in an airduct of thermal power plant, coal pulverizer outlet etc.; general serviceable life is all very short; only be about 6 months, the longlyest also be no more than 10 months.
Summary of the invention
The utility model provides a kind of thermocouple protection cover, and it can solve, and the protective sleeve resistance to abrasion is not high in the prior art, serviceable life short, the problem of easy fracture.
In order to address the above problem, the scheme that the utility model adopts is: it comprises metal sleeve, and described metal sleeve is with the multistage wear-resistant sleeve outward.
Above-mentioned wear-resistant sleeve can be selected ceramic pipe for use; Can be provided with adhesive-layer between above-mentioned metal sleeve and the described wear-resistant sleeve; Above-mentioned metal sleeve lower end is provided with the plug of one end greater than described metal sleeve external diameter.
The utility model compared with prior art has following beneficial effect:
1, resistance to abrasion height, long service life, easy fracture not.Because metal tube is with the multistage porcelain bushing outward, its anti-wear performance is good, is more than 5 times of prior art, is squeezed, easy fracture not during flexural deformation.
2, shock resistance is good.Owing to be provided with adhesive-layer between metal sleeve and the wear-resistant sleeve, when being subjected to sharp pounding, play buffer action, lower the vibrations of metal sleeve and wear resistance ceramic tube.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
As Fig. 1, among the embodiment shown in Figure 2, it comprises terminal box 1 the utility model, metal sleeve 2 and joint 3, the metal sleeve 2 outer multistage wear resistance ceramic tubes 4 that are with, too high or when being squeezed in temperature, there is the space to expand with heat and contract with cold or flexural deformation for ceramic pipe 4 between wear-resistant ceramic pipeline section and the section, be provided with adhesive-layer 5 between metal sleeve 2 and the ceramic pipe 4, when being subjected to judder, adhesive-layer plays buffer action, reduce the vibrations of metal sleeve 2 and wear resistance ceramic tube 4, be provided with the T type plug 6 of one end greater than this metal sleeve external diameter in metal sleeve 2 lower ends, this plug plays position-limiting action, makes metal sleeve 2, combination between adhesive-layer 5 and the wear resistance ceramic tube 4 is tightr.
Claims (4)
