Description

A kind of water supply and sewerage pipeline connecting structure

Technical field

This utility model relates to plumbing technical field, particularly relates to a kind of water supply and sewerage pipeline connecting structure.

Background technology

Presently used water supply and sewerage pipeline (including industrial and civilian) has steel pipe, galvanized pipe, pure plastic pipe (to include substantially PVC, PP, PPR, PE etc.), cast iron pipe, pipe of cement and multiple tube, rubber-lined pipe and spray pipe etc..And galvanized pipe and pipe of cement are existing The most being impermissible for use, steel pipe is only used in the special occasions such as High Temperature High Pressure substantially because of the reason such as cost and anticorrosion, as The lowest but the same with the pipe of cement percolation ratio high pollution environment of cast iron pipe cost of draining also reduce use, line with rubber and spray pipe because of Technique and cost reason are seldom seen, and connect by feat of natural antiseptic power and modern science and technology and producing Progressing greatly of technique, the stable raising of properties of product and the reduction of cost, plastic pipe particularly steel-plastics composite pipe obtains greatly in recent years The popularization of area, in the substantial amounts of water supply and sewerage pipeline being applied to productive life.

It is known that the plastic cement such as PE, PP, PVC, PPR the most used are antiseptical good materials, same is the most all electric Insulator, although steel-plastics composite pipe has metal reinforcement in the centre of tubing, but most metals reinforcement is with holes or spiral shell Rotation shape and netted, it is ensured that the not all standing to plastic layer, and metal reinforcement predominantly strengthens pipeline rigidity, to conduction Property no requirement (NR).

In order to realize the damage Fast nondestructive evaluation to plastic cement and compound pipeline complex pipeline, early stage breakage early warning particularly can be realized, Preventing plumbing from leaking pollution environment, it is achieved online monitoring in real time and detection, applicant proposes to increase in existing tubing one Layer conducting film so that supplying drainage carries out damage testing and early warning by electric method and algorithm, accomplish to pinpoint the problems in time and Time safeguard.Effectively prevent from oozing, leaking, economize on resources, protect environment, also can prevent secondary disaster.

Secondly, corresponding with the function that existing pipeline is only used as plumbing effect, existing pure plastic pipe or the connection of multiple tube Mode is substantially that glue is bonding and two kinds of methods of electric heating melting. and in both methods of attachment, the purest plastic pipe fitting still adds The pipe fitting of reinforcement all can only realize the effective connection between two tubing, without realizing the demand of electric connection between tubing.

With material behavior and the structure present situation of existing tubing, the real-time damage testing of water supply and sewerage pipeline to be realized is very difficult 's.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, with Under in conjunction with the accompanying drawings and embodiments, this utility model is further elaborated.Should be appreciated that concrete reality described herein Execute example only in order to explain this utility model, be not used to limit this utility model.

Embodiment one

This utility model first embodiment provides a kind of water supply and sewerage pipeline connecting structure, as depicted in figs. 1 and 2, comprises the One pipeline 10, second pipe 20 and pipe joint 30, socket pipe joint 30 outside the first pipeline 10 and second pipe 20, then manage Joint 30 is bonding with one end glue of one end of the first pipeline 10 and second pipe 20 or hot-melt adhesive paste, so that the first pipeline 10 couple together with second pipe 20；As it is shown in figure 1, the first pipeline 10 comprises inner insulating layer 11 and is arranged at outside inner insulating layer 11 Conductive layer 12, second pipe 20 comprises inner insulating layer 21 and is arranged on the conductive layer 22 outside inner insulating layer 21；Pipe joint 30 comprise insulating barrier.Conductive layer in described first pipeline or second pipe is conducting metal or conductive film, described insulation Internal layer and insulating barrier be PE, PP, PVC, PPR any one.Axially disposed at least gold in the insulating barrier of described pipe joint Belong to bus 31, the metal conductive strips of 2,4,6 etc. quantity can be arranged as required to, when arranging many metal conductive strips Time, in the range of each bus is evenly distributed on the tube wall of pipe joint.Metal conductive strips is one-body molded with described pipe joint insulating barrier In described insulating barrier, or length more than insulating barrier isometric with insulating barrier or less than the length of insulating barrier.Described metallic conduction Bar is provided with connection end 32 at the two ends of pipe joint, in the present embodiment, as in figure 2 it is shown, described insulating barrier arranges groove in end, Make described connection end 32 be exposed to the end of pipe joint, be conveniently connected with the conductive layer of the first pipeline or second pipe.Such as Fig. 1 Shown in, the end 32 that connects of the metal conductive strips of pipe joint 30 is overlapped with the conductive layer of corresponding pipeline by wire 1, makes the first pipeline 10 keep electric connection with the conductive layer of second pipe 20 by metal conductive strips.

In order to make pipe joint part can realize the detection of full tube wall, described pipe joint 30 outer wrapping conductive film layer is (in figure not Illustrate), and make metal conductive strips and conductive film layer electric connection, now, metal conductive strips can not be through tube joint total length, this The full tube wall of sample pipe joint can pass through current detection signal, when generator tube joint breakage, in that context it may be convenient to breakage detected Place.When pipeline or pipe joint rupture, the conducting liquid such as the water in pipeline and the conductive layers make contact in pipeline, cause inspection Survey device to test to the signal of telecommunication change, the judgement of pipeline breaking can be made.

This programme goes for more pipeline configuration, such as, at the first pipeline with second pipe at conductive layer peripheral hardware Put insulating outer layer, form the water supply and sewerage pipeline of three-decker.Or between inner insulating layer and insulating outer layer, also set up enhancement Layer, Described enhancement Layer is arranged on inner side or the outside of conductive layer, and described enhancement Layer is grid or mesh or screw-like.

The water supply and sewerage pipeline connecting structure of implementation above, by arranging metal conductive strips on pipe joint, then metal is led The conductive layer of two pipelines that pipe joint is connected by electricity bar couples together, so that two pipelines connected by pipe joint can be same Time receive the detection electric current of damage detection device, thus simplify the damage testing program of whole water supply and sewerage pipeline, significantly drop The low cost of water supply and sewerage pipeline damage testing, accomplishes to pinpoint the problems in time, safeguard in time.Effectively prevent from oozing, leaking, save money Source, protection environment, also can prevent secondary disaster.
