Abstract
The utility model discloses a conductive liquid leakage detection cable. The cable comprises a protective layer and electric core wires arranged inside the protective layer. The conductive liquid leakage detection cable is characterized in that the electric core wires which are arranged to form a straight line-shaped structure includes two alarm power source lines and two sensing lines, wherein the alarm power source lines are arranged in the middle of the cable, and the two sensing lines are respectively arranged at two sides of the alarm power source lines; and the protective layer is provided with grooves at two ends of the sensing lines so as to expose the sensing lines. The conductive liquid leakage detection cable has the following advantages that: through adopting copper conductors and conductive PVC layers, as well as a method in which the grooves are slotted on the protective layer to expose the sensing lines, the conductive liquid leakage detection cable can be laid at the periphery of a liquid storage device, as a result, any leakage point of the liquid storage device can be timely detected; and further, a problem of incapability of detecting leakage points of the whole liquid storage device caused by small detection points existing in a traditional method can be solved.
Description
Technical field
The utility model relates to the cable and wire field, is specifically related to a kind of conducting liquid and leaks the detecting cable.
Background technology
Fluid-carrying lines, hold-up tank, all kinds of plant equipment, due to installation and maintenance or extended active duty, the superpressure operation, the many reasons such as material corrosion and ageing, the run, drip, leak phenomenon is seen everywhere.Some lower boiling solvents, fuel leak, and are difficult to judge from the ground vestige, particularly basin exports the connection places such as first valve, flanged fitting, if leak untimely discovery, consequence is very dangerous, the event that fires that some are produced, storage unit occurs, multi-source is in leakage.To leak in order finding as early as possible, to win the time of speedily carrying out rescue work, people have invented multinomial warning device.
The method of testings that adopt sensor, change judgement by parameters such as pressure, flow velocity, flow, temperature more in the market; Judge by sound; Detect or add detection material etc. with laser imaging, conducting liquid being carried out leakproof detect.Adopt the method for testing of sensor, the leakage of the position liquid of placing a point of inductor can only be detected, and the leakage situation of a plurality of positions can't be detected, as will realize, need by a plurality of inductors are set, thereby improved testing cost.
The utility model content
The purpose of this utility model is for above-mentioned deficiency, provides a kind of reasonable in design, simple in structure, and production cost is low, and the conducting liquid that sensing range is large leaks the detecting cable.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of conducting liquid leaks the detecting cable, it comprises protective seam, and the battery core line that is positioned at protective seam inside, described battery core line is " one " word arrangement, comprise two warning power leads and two lines of induction, wherein two warning power leads are positioned in the middle of cable, and two lines of induction lay respectively at warning power lead both sides; Described protective seam is provided with groove at the two ends that the line of induction is arranged, and the line of induction is exposed.
Protective seam adopts linear low density polyethylene; have and bear dirty and the advantage of dust easy to clean; in addition in the recessing respectively of the both sides of the line of induction; the line of induction is exposed; can guarantee and the contacting of leakage liquid, when two lines of induction contacted with leakage liquid, two lines of induction were owing to being to consist of by conducting electricity the PVC Polyvinylchloride; so two the line of induction forms short circuit, connect alarm and send alerting signal and work.
After the cable covering extrusion is completed, then pass through twisting technique, after making conductive core line in "S" shape, the slot of protective seam recessing exceeds the line of induction, just in time can form the invasion that " dust shield cover " prevents dust at line of induction upper space.
Also be provided with locating slot on described protective seam.
Described line of induction center is at least two conductive monofilaments that tangle again and be combined each other, and conductive monofilament is coated with conduction PVC polyvinyl chloride layer; Described conduction PVC layer cross section is rounded, and the one side is exposed by the protective seam groove.
Described warning power lead center is at least two conductive monofilaments that tangle again and be combined each other, and conductive monofilament is coated with conduction PVC layer, and conduction PVC layer is coated with insulation course; Described insulation course and conduction PVC layer cross section are rounded.
Described protective seam and insulation course are made by the LLDPE material.
The beneficial effects of the utility model are: add conduction PVC layer by adopting copper conductor; protective seam is taked to slot and is exposed the mode of the line of induction; can be laid on the liquor storage device periphery; any one point of liquor storage device has leakage; can in time detect; avoid classic method detecting point little, and can't detect the phenomenon of whole liquor storage device leakage point.

Embodiment:
Embodiment: referring to Fig. 1, the present embodiment provides a kind of conducting liquid to leak the detecting cable, it comprises protective seam 1, and the battery core line that is positioned at protective seam 1 inside, described battery core line is " one " word arrangement, comprise two warning power leads 2 and two lines of induction 3, wherein two warning power leads 2 are positioned in the middle of cable, and two lines of induction 3 lay respectively at warning power lead 2 both sides; Described protective seam 1 is provided with groove 4 at the two ends that the line of induction 3 is arranged, and the line of induction 3 is exposed.
After cable covering 1 extrusion is completed, then pass through twisting technique, after making conductive core line in "S" shape, the slot of protective seam 1 recessing 4 exceeds the line of induction, just in time can form the invasion that " dust shield cover " prevents dust at the line of induction 3 upper spaces.
Also be provided with locating slot 5 on described protective seam 1.
The described line of induction 3 centers are at least two conductive monofilaments 6 that tangle again each other and be combined, and conductive monofilament is coated with conduction PVC layer 7; Described conduction PVC layer cross section is rounded, and the one side is exposed by protective seam 1 groove 4.
