Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make clear and definite definitions of the protection scope of the present invention.
Referring to fig. 1 to 3, an embodiment of the present invention includes:
a multipoint temperature measuring device for an inner wall of a metal pipeline comprises: one section or multistage cylinder 1 and armor thermocouple 2, the axial is provided with the mounting hole 10 with 3 inner wall measuring points of metal heating pipe corresponding quantity on the cylinder 1, is equipped with armor thermocouple 2 in the mounting hole 10, and the diameter of mounting hole 10 is unanimous with the diameter of armor thermocouple 2, and the mounting hole 10 is unanimous with the measuring point angle, for example set for a certain hole and be 0 degree, next hole is 30 degrees, next hole is 60 degrees angles again, expand in proper order, as shown in fig. 1 and 2, the processing of bending backward after the measuring end of armor thermocouple 2 stretches out mounting hole 10.
In a low-temperature environment, the cylinder 1 is made of a teflon insulating material, and in a high-temperature environment, the cylinder 1 is made of a corundum ceramic insulating material.
The diameter of the armored thermocouple 2 is 0.5 mm-1 mm, the thin armored thermocouple 2 ensures quick response of measurement, and the thin armored thermocouple 2 is turned out from the cylinder 1 to be more convenient to bend, so that the armored thermocouple can be contacted with the metal heating pipe 3 to adhere to the wall.
The diameter of the cylinder 1 and the diameters of the two armored thermocouples 2 are consistent with the diameter of the inner hole of the metal heating pipe 3.
When the multipoint temperature measuring device for the inner wall of the metal pipeline works, a thin-diameter armored thermocouple 2 wire penetrates into a plurality of mounting holes 10 of machined multi-hollow insulating cylinders 1, 10mm of the front section of a thermocouple probe 2 stretches out of the mounting holes 10 and then is bent at a position needing to be measured, the insulating cylinders 1 are turned out and fully contact with the inner wall of a metal heating pipe 3, and therefore the temperature of the corresponding height (depth) and angle of the inner wall of the metal heater 3 is accurately measured.
The utility model relates to a multiple spot temperature measuring device for metal pipeline inner wall, the modern design, simple structure, exquisiteness, performance safe and reliable, and easily installation can be used for the inside not co-altitude not temperature measurement of different angles adherence of tubular metal resonator heater.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
