Abstract
The utility model relates to a flexible thermocouple which comprises a plurality of flexible thermocouples, and the plurality of the flexible thermocouples are integrated and fixed together by a sealing component. The sealing component comprises a connecting part with external threads at two ends, a screw cap in threaded fit with the upper end of the connecting part, a tapered rubber seal ring and a gasket, wherein the tapered rubber seal ring is placed in a tapered hole which is arranged at the upper end of the connecting part and matched with the tapered rubber seal ring, the gasket is placed in a space of the connecting part on the tapered rubber seal ring, which is combined with the screw cap, the tapered rubber seal ring is provided with a plurality of holes matched with the outer diameter of the flexible thermocouples, and the connecting part, the screw cap and the gasket respectively comprise through holes for leading the plurality of the flexible thermocouples to pass through. The plurality of the thermocouples are sealed and fixed together through the sealing component, when the thermocouples need to be replaced, only the screw cap needs to be loosened, then the seal ring can be recovered to the original shape naturally, and the thermocouples can be extracted one by one, and the flexible thermocouple has the advantages of being good in sealing performance, being convenient for maintenance and replacement, being compact in structure and the like.
Description
Technical field
The utility model relates to a kind of flexible thermal galvanic couple, and it is integrated to relate in particular to a kind of flexible thermal galvanic couple that contains many flexible thermal galvanic couples.
Background technology
In the enterprises such as petrochemical industry, electric power, metallurgy large-scale machinery and equipment such as steam turbine, compressor, generator, fan blower and pump are arranged all now, and these machinery and equipment main shafts all are to want long-term high-speed rotation, will make damage of bearings easily in case temperature is for a long time too high, so the bearing shell in the machinery and equipment, the temperature of bearing need monitoring in real time, could guarantee the long-term normal operation of plant equipment.
The method that present stage is measured bearing shell, bearing temperature all is perforate on bearing seat, and boring is related to its intensity on the bearing seat, so a bearing seat is only offered a threaded hole usually; And a large amount of lubricating oil or cold oil are arranged in the bearing seat, so when being installed, thermometer also needs to accomplish sealing.And a general threaded hole can only inject a thermometer, could guarantee its sealing; Multi-point temperature measurement then needs many thermopairs to be fixed together earlier with glue or welding in this way, and then installs with screw thread, or directly directly seals fixing seal with glue on the threaded hole of bearing seat, is not easy to maintain and replace like this.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of to have a flexible thermal galvanic couple that contains many flexible thermal galvanic couples integrated, use the defective that exists to overcome existing many flexible thermal galvanic couples that are provided with that separate.
The technical scheme that the utility model adopted is: a kind of flexible thermal galvanic couple, comprise many flexible thermal galvanic couples, and described many flexible thermal galvanic couples are fixed together by seal assembly is integrated.
The further technical scheme of the utility model is: described seal assembly is provided with externally threaded web member, is formed with nut, cone rubber O-ring seal and the packing ring of web member upper end threaded engagement by two ends, the bellmouth that described cone rubber O-ring seal places the web member upper end to cooperate with it, packing ring places in the space of web member above the cone rubber O-ring seal and nut combination, described cone rubber O-ring seal is provided with a plurality of holes of matching with flexible thermal galvanic couple external diameter, and described web member, nut and packing ring all have allows many through holes that the flexible thermal galvanic couple passes.
The beneficial effects of the utility model: the seal assembly by having the cone rubber O-ring seal with many thermopair sealing and fixing together, pass through tightening nuts, packing ring can push the taper rubber seal, make the cone rubber O-ring seal between bellmouth and thermopair, produce compression deformation, thereby reach sealing effectiveness; When needs are changed thermopair, only need nut is unclamped, O-ring seal can restore to the original state by nature, and thermopair can singly prop up extraction; Has good seal performance, convenient maintenance and replacement, advantages such as compact conformation.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 is example structure synoptic diagram of the utility model.
Embodiment
Embodiment illustrated in fig. 1, comprise many flexible thermal galvanic couples 1 and with the integrated fixing seal assembly together of many flexible thermal galvanic couples 1.Described seal assembly is provided with externally threaded web member 2, is formed with nut 5, cone rubber O-ring seal 3 and the packing ring 4 of web member 2 upper end threaded engagement by two ends, the bellmouth that cone rubber O-ring seal 3 places web member 2 upper ends to cooperate with it, packing ring 4 places in the space of web member 2 above the cone rubber O-ring seal 3 and nut 5 combinations, cone rubber O-ring seal 3 is provided with a plurality of holes of matching with flexible thermal galvanic couple 1 external diameter, the quantity in hole is suitable with thermopair quantity, thermopair quantity is generally 2-8 and props up, 2-8 hole of cone rubber O-ring seal corresponding configuration; Described web member 2, nut 5 and packing ring 4 all have allows many through holes that flexible thermal galvanic couple 1 passes.Seal assembly is fixed on flexible thermocouple cold junction position.
During use, the threaded hole on seal assembly and the equipment axis bearing is fixed, the flexible thermal galvanic couple can be turned adherent thermometric around bearing shell, bearing.When needs are changed thermopair, only need nut is unclamped, O-ring seal can restore to the original state by nature, and thermopair can singly prop up to extract out and change.
