In the description of the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the invention can be understood by concrete condition.
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, the present invention 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 to be arranged in external protection 1 and to be arranged in parallel, 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, ground wire 3 ground connection is arranged, external protection 1 material is crosslinked polyethylene, external protection 1 is syllogic calabash shape, increase external protection 1, two alarming lines 2 and ground wire 3 are be arranged in parallel, effective and external environment condition is isolated, effectively prevent condensed steam or condensed water from bringing adverse effect to detection, external protection 1 adopts the crosslinked polyethylene material of insulation, and the convenient steel pipe that against is laid, and when steel pipe occurs to leak, degree of reaction is also sensitiveer than that structure be placed on traditionally in the middle of heat-insulation layer, two alarming lines 2 integration and be arrangeding in parallel, lays convenient, and impedance, and when there is small leakages, the situation that impulse wave reflects all can clearly show, improving measurement accuracy, external protection 1 adopts syllogic calabash shape, effectively two alarming lines 2 and ground wire 3 can be separated, and can ensure the depth of parallelism between three, ground wire 3 is set and can promotes fail safe, preferably, the thickness of external protection 1 is 0.5mm, and thickness is all with consistent, easily integrally formed in the fabrication process, and intensity is good.
Preferably, the diameter of alarming line is 1mm, traditional bare copper wire diameter be 1.38mm, 1mm ensure pulse signal transmission again relatively before structure save material; More preferably, alarming line is made up of 7 strands of copper wires, and copper wire current-carrying capacity of cable is large: because resistivity is low, and the ampacity that the copper cabling with cross section allows than aluminium cable is high by about 30%; The copper cabling loss of voltage is low: because the resistivity of copper cabling is low, when same current is flow through in same cross section, the voltage drop of copper cabling is little, therefore, same transmission distance, higher quality of voltage can be ensured, in other words, under the voltage drop condition allowed, copper cabling transmission of electricity can reach larger distance, namely area coverage of powering is large, is conducive to the planning of network, reduces the magnitude setting of supply terminals; Copper cabling heating temp is low, makes operation safer; Copper cash due to the resistivity of copper low, energy consumption is low; Copper cabling is anti-oxidant, corrosion-resistant, and the connector stable performance of copper cabling, can not have an accident due to oxidation; Copper cash is flexible, easy construction, and the camber radius of permission is little, so turn round conveniently, poling is easy, due to copper cash antifatigue, repeatedly bending not easy fracture, so easy-to-connect; Mechanical strength again due to copper cash is high, can bear larger mechanical tensile forces.
Preferably, external protection 1 comprises first area 13 and second area 12, first area 13 is coated on outside alarming line, second area 12 is coated on outside ground wire 3, first area 13 is red, and second area 12 is black, and external protection arranges color, while distinguishing alarming line and ground wire, improve aesthetic property again; More preferably, first area 13 is provided with knuckle 11 with the junction of second area 12, facilitates one-body molded, also avoids stress in integrally formed process to concentrate, promote intensity while attractive in appearance.
In the tubing production process or installation process of reality, moisture can be entered in foam, when starting in pipeline to supply cold water, these moistures will be met cold and condensation is got off, traditional alarming line is because the exposed short circuit that may will cause loop because of condensed water, cannot normally measure, external protection 1 condensed steam or condensed water can be avoided to bring to detection adverse influence, two alarming line 2 depth of parallelisms of this structure are arranged in addition, and traditional two alarming lines are laid by people in process of production completely by hand, the depth of parallelism is not high especially, impedance between two alarming lines, 2 pairs of ground wires 3 is very even, impedance, when there is small leakage, the situation of impulse wave reflection all can clearly show, improving measurement accuracy, in addition because external protection 1 is isolation material, steel pipe can be directly against, when steel pipe occurs to leak, degree of reaction is also sensitiveer than that structure be placed on traditionally in the middle of heat-insulation layer, total is simple, reduce cost to greatest extent, can effectively prevent condensed water or condensed steam, and accuracy of detection is high.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
