In the description of creating at the utility model, it should be noted that, unless separately had clear and definite regulation and limitFixed, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be fixingConnecting, can be also to removably connect, or connects integratedly; Can be mechanical connection, can be also electricityConnect; Can be to be directly connected, also can indirectly be connected by intermediary, can be in two elementsThe connection of portion. For the ordinary skill in the art, can understand above-mentioned art by concrete conditionThe concrete meaning of language in the utility model is created.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, the utility model is refrigeration piping detection alarming line, comprise external protection 1,Ground wire 3 and two alarming lines 2, ground wire and two alarming lines 2 are arranged in external protection 1 and parallel establishingPut, two alarming lines 2 be located at the both sides of ground wire 3, alarming line one end connects outside detecting instrument,The other end connects outside central data processing unit, and ground wire 3 ground connection arrange, and external protection 1 material isCrosslinked polyethylene, external protection 1 is syllogic calabash shape, increases external protection 1, by two alarming lines2 and ground wire 3 be arranged in parallel, effectively and external environment condition isolate, effectively prevent condensed steam or coldSolidifying water brings adverse effect to detecting; External protection 1 adopts the crosslinked polyethylene material of insulation, conveniently willIt is pasting steel pipe and is laying, and in the time that steel pipe occurs to leak, degree of reaction is also than being placed on traditionally in the middle of heat-insulation layerThat structure is sensitiveer; Two alarming lines 2 are integrated and be arranged in parallel, lay convenient, andAnd impedance, in the time there is small leakage, the situation of impulse wave reflection all can clearly show, and carriesRise certainty of measurement; External protection 1 adopts syllogic calabash shape, can be effectively by two alarming lines 2 and groundLine 3 is separated, and can ensure the depth of parallelism between three; Ground wire 3 is set and can promotes security; ExcellentSelection of land, the thickness of external protection 1 is 0.5mm, thickness is all with consistent, easily one in manufacture processBe shaped, and intensity is good.
Preferably, the diameter of alarming line is 1mm, and traditional bare copper wire diameter is 1.38mm, and 1mm ensures pulseMaterial has been saved in the transmission of signal again relative structure before; More preferably, alarming line is by 7 strands of copper wiresComposition, copper wire current-carrying capacity of cable is large: because resistivity is low, with the copper cabling in cross section than aluminium core electricityHigh 30% left and right of current-carrying capacity that cable allows; The copper cabling loss of voltage is low: due to the resistivity of copper cablingLow, the in the situation that of flowing through same current in same cross section, the voltage drop of copper cabling is little, therefore, sameTransmission distance, can ensure higher quality of voltage, in other words, allow voltage drop condition under,Copper cabling transmission of electricity can reach larger distance, and the area coverage of powering is large, is conducive to the planning of network,Reduce the magnitude setting of supply terminals; Copper cabling heating temp is low, makes to move safer; Copper cash byResistivity in copper is low, and energy consumption is low; Copper cabling is anti-oxidant, corrosion-resistant, and the company of copper cablingJoint performance is stable, can be because oxidation has an accident; Copper cash is flexible, and easy construction allowsCamber radius little, so turn round conveniently, poling is easy, due to copper cash antifatigue, bending is not repeatedlyEasy fracture, so easy-to-connect; Because the mechanical strength of copper cash is high, can bear larger machinery and draw againPower.
Preferably, external protection 1 comprises first area 13 and second area 12, and first area 13 is coatedIn alarming line outside, second area 12 is coated on ground wire 3 outsides, and first area 13 is red, and secondRegion 12 is black, and external protection arranges color, when distinguishing alarming line and ground wire, has promoted againAesthetic property; More preferably, first area 13 is provided with knuckle 11 with the junction of second area 12,Facilitate one-body moldedly, time attractive in appearance, also avoid in integrally formed process stress to concentrate, promote intensity.
In actual tubing production process or installation process, in foam, can enter moisture, when opening in pipelineBegin supply when cold water, and these moistures will be met cold and condensation is got off, and traditional alarming line may because exposedWill cause because of condensed water the short circuit in loop, cannot normally measure, it is cold that external protection 1 can be avoidedSolidifying water vapour or condensed water bring to detecting adverse influence, two of this structure alarming lines 2 are flat in additionRow degree arranges, and two traditional alarming lines are laid by people in process of production completely by hand, and the depth of parallelism is notBe high especially, two alarming lines 2 are very even to the impedance between ground wire 3, and impedance, when small letting out occursWhen dew, the situation of impulse wave reflection all can clearly show, improving measurement accuracy, in addition because of outsideProtective layer 1 is insulation material, can directly paste steel pipe, in the time that steel pipe occurs to leak, degree of reaction also thanBe placed on traditionally the middle that structure of heat-insulation layer sensitiveer, total is simple, falls to greatest extentLow cost, can effectively prevent condensed water or condensed steam, and accuracy of detection is high.
Above an embodiment of the present utility model is had been described in detail, but described content is only this realityWith novel preferred embodiment, can not be considered to for limiting practical range of the present utility model. Fan YibenEqualization variation and improvement etc. that utility model application scope is done, all should still belong to of the present utility model specialWithin profit covering scope.
