Description

Technical Field

[0001] The utility model belongs to the technical field of thermocouple wires, in particular to a high-temperature resistant thermocouple compensation wire. Background Art

[0002] High temperature resistant thermocouple compensation wire is mainly used in thermocouple measurement system. High temperature resistant thermocouple compensation wire is usually made of copper, nickel or chromium-nickel alloy. These materials have good high temperature oxidation resistance and electrical conductivity, which can ensure the stability and accuracy of signal transmission in high temperature environment. It has excellent acid, alkali, wear resistance and non-flammability, and can be used in high temperature environment for a long time.

[0003] At present, in the actual application of high temperature resistant thermocouple compensation wires, as the ambient temperature rises, the temperature of the wire itself will also rise accordingly, which will increase the thermal expansion coefficient of the wire, and the wire material will expand due to heat, resulting in a decrease in the compensation effect and eventually damage the wire;

[0004] In order to solve the above problems, the present application proposes a high temperature resistant thermocouple compensation wire. Utility Model Content

[0005] The utility model aims to provide a high temperature resistant thermocouple compensation wire, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a high-temperature resistant thermocouple compensation conductor, comprising: a cable core and an inner coating layer and an outer coating layer on the outer side thereof; an inner arc pad for blocking the continuous inward transfer of temperature is arranged on the outer side of the inner coating layer, an outer arc pad for enhancing the external force resistance performance is arranged on the outer side of the inner arc pad, the inner arc pad and the outer arc pad are combined to form a storage cavity, which is used to fill phase change particles to absorb the heat transferred from the outside to the inside, and the phase change particles produce a phase change when the external environment temperature decreases to release the heat to the outside.

[0008] Furthermore, a blocking block is provided on one side of the outer arc-shaped pad, and side pads for bonding the outer arc-shaped pad are provided on both sides of the blocking block.

[0009] Furthermore, a partition for separating the storage cavity is arranged on the inner side of the outer arc-shaped pad.

[0010] Furthermore, the separator is provided with flow holes inside for the phase change particles to flow.

[0013] Furthermore, the phase change particles are filled inside the phase change particles by filling.

[0014] The utility model has the following beneficial effects:

[0015] The utility model combines the inner arc pad with the outer arc pad and utilizes phase change particles, which can block and adsorb the external high temperature, so that the phase change particles produce phase change to block the heat from being transferred inwards, and then when the external temperature decreases, the heat inside the phase change particles is released outwards and the phase change is restored, so that the external heat is blocked in the outer layer area, effectively preventing the cable from expanding and bulging due to heat, prolonging the service life of the cable, and also enhancing its stability during use;

[0016] The utility model assembles the inner arc pad and the outer arc pad into one body before the extrusion process, and then releases the blocking block to seal the blocking groove through the winding mechanism, and at the same time fills the interior of the storage cavity so that the phase change particles are filled inside, and finally releases the combined mechanism to the outside of the cable core to form a coating, and the coating operation can be carried out together with it. The combined structure also enhances the cable's resistance to external forces, adapts to external extrusion forces and prevents damage to the internal structure.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 As shown, the utility model is a high temperature resistant thermocouple compensation wire, comprising: a cable core 1 and an inner coating layer 2 and an outer coating layer 3 on the outer side thereof;

[0028] The outer side of the inner coating layer 2 is provided with an inner arc pad 4 for preventing the temperature from being continuously transferred inwards, and the outer side of the inner arc pad 4 is provided with an outer arc pad 5 for enhancing the external force resistance performance. The inner arc pad 4 and the outer arc pad 5 are combined to form a storage cavity 11, which is used to fill the phase change particles 12 to absorb the heat transferred from the outside to the inside. When the external environment temperature decreases, the phase change particles 12 produce a phase change to release the heat outwards;

[0029] The present embodiment provides a functional internal high-temperature cable structure. The phase change particles 12 can be filled inside through the combination of the inner arc pad 4 and the outer arc pad 5, and installed together inside the sheathing structure of the cable. The high temperature of the external environment can be intercepted in the outer area so that it cannot be continuously transmitted inward, thereby avoiding problems such as expansion and deformation caused by high temperature, and extending the service life of the cable conductor.

[0030] A blocking block 6 is disposed on one side of the outer arc-shaped pad 5 , and side pads 7 for bonding the outer arc-shaped pad 5 are disposed on both sides of the blocking block 6 . The blocking block 6 is also used to limit the phase change particles 12 to prevent overflow.

[0031] A partition 8 is provided on the inner side of the outer arc-shaped pad 5 to separate the storage cavity 11 . The partition 8 can resist the external squeezing force to prevent the cable conductor from being greatly deformed.

[0032] The separator 8 is provided with flow holes 9 for the phase change particles 12 to flow through, and the connection increases the occupied space and makes the phase change process more stable.

[0033] Among them, positioning protrusions 10 for fixing the outer arc-shaped pad 5 are arranged on the outer sides of the two ends of the inner arc-shaped pad 4, and are located on one side of the protruding plate body mechanism at the two ends of the inner arc-shaped pad 4.

[0034] The outer arc-shaped pad 5 has a plugging groove 13 inside for installing the blocking block 6 , which is also used as an inlet for filling the phase-change particles 12 .

[0035] The phase change particles 12 are filled into the interior of the phase change particles 12 by filling.

[0036] It can be understood that the utility model can effectively prevent the high temperature of the external environment from being continuously transmitted to the inside of the cable conductor, so as to prevent the cable conductor from expanding and deforming due to the high temperature, thereby ensuring the stable operation of the cable conductor, extending its service life and improving its practical effect.

[0037] A specific application of the operation process of this embodiment is: before the extrusion process of the cable, the inner arc pad 4 and the outer arc pad 5 are assembled into one by an external mechanism, and then the blocking block 6 is placed outside the winding mechanism to seal the blocking groove 13. At this time, the side pad 7 is adhered to the outer surface of the outer arc pad 5. At the same time, the storage cavity 11 is filled inside by an external filling machine, so that the phase change particles 12 are filled inside, and finally the assembled mechanism is placed outside the cable core 1 to form a coating, and the coating operation is performed together with it to form a functional cable conductor; at this time, the phase change particles 12 absorb the heat transferred from the outside to the inside to produce a phase change, and the heat is blocked by the inner arc pad 4 to prevent continuous inward transfer, and then when the temperature of the external environment drops, the phase change particles 12 produce a phase change recovery again, and release the accumulated heat to the outside, thereby effectively preventing the cable from being affected by the high temperature of the external environment and causing expansion and bulging, thereby ensuring the service life of the cable and improving its high temperature resistance.
