Abstract
The utility model discloses a kind of anti-leak natural gas line for pipe network monitor system, comprising: interior conduit, Outer Tube, dunnage, pipe of reporting to the police, film, cloche; Interior conduit is used for delivery of fuel gas; Outer Tube is enclosed within the outside of interior conduit by the dunnage being arranged on interior conduit two ends; The inwall of Outer Tube, the outer wall of interior conduit and dunnage form enclosed space, are full of nitrogen in enclosed space; Warning pipe is vertically installed in one end near dunnage, outside of Outer Tube, and pipe of reporting to the police is communicated with enclosed space; Warning pipe is divided into cavity of resorption and epicoele, the powder of the solid redness of epicoele by the film being arranged at middle part; It is outside that transparent cloche is arranged at warning pipe.The utility model solves that existing gas pipeline monitoring means are single, and cost is high, the technical problem that the life-span is low.
Description
Technical field
The utility model relates to Supervisory control field, particularly a kind of anti-leak natural gas line for pipe network monitor system.
Background technique
Town gas pipe is embedded in the underground of the high risk zone such as densely populated place and traffic prosperity more; because pipeline is subject to the corrosion function of the soil solution and town gas pipe user is numerous for a long time; cannot add cathodic protection, the tube wall of pipeline can thinning, perforation gradually, causes gas leakage.The pressure range of current city gas steam line is mostly 0.2-0.4MPa, belong to middle pressure pipeline, pipe leakage mostly is underground corrosion perforation and leaks, leakage rate is relatively little, gas leakage can not be diffused into ground at short notice, and due to the complexity of surrounding enviroment factor, often there is serious phenomenon of collaborating in gas leakage, gather in nigh cable channel and cable sheath, or diffuse to the adjunct such as periphery rain row, dirty row, horse cucurbit to come out, range of scatter is comparatively large, finds to there is hysteresis quality, the more difficult identification of leakage point.Simultaneously because the startup of earth's surface vehicular traffic, people are that the uncontrollable factor such as smoking, the sparking of electricity consumption facility is more, easily there is Fire explosion after gas leakage, cause great casualties, economic loss and social influence.
Model utility content
The utility model object is to provide a kind of anti-leak natural gas line for pipe network monitor system, and solving existing gas pipeline, to carry out the means of anti-leak monitoring single, and cost is high, the technical problem that the life-span is low.
The technical solution adopted in the utility model is: a kind of anti-leak natural gas line for pipe network monitor system, comprising:
Interior conduit, Outer Tube, dunnage, pipe of reporting to the police, film, cloche;
Interior conduit is used for delivery of fuel gas;
Outer Tube is enclosed within the outside of interior conduit by the dunnage being arranged on interior conduit two ends; The inwall of Outer Tube, the outer wall of interior conduit and dunnage form enclosed space, are full of nitrogen in enclosed space;
Warning pipe is vertically installed in one end near dunnage, outside of Outer Tube, and pipe of reporting to the police is communicated with enclosed space; Warning pipe is divided into cavity of resorption and epicoele, the powder of the solid redness of epicoele by the film being arranged at middle part;
It is outside that transparent cloche is arranged at warning pipe.
Further, Outer Tube arranged outside has corrosion-resistant coating.
Further, cloche and Outer Tube are welded to connect.
Further, warning pipe is positioned in the middle part of cloche.
Further, cloche inwall is provided with rough projection.
The utility model provides a kind of anti-leak natural gas line for pipe network monitor system, when generation gas leakage, maintenance man can position it easily, with tradition by compared with electronic monitoring means, has that cost is low, the life-span long, broad-spectrum advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-leak natural gas line for pipe network monitor system in the utility model.
Embodiment
As shown in Figure 1, a kind of anti-leak natural gas line for pipe network monitor system, comprising:
Interior conduit 2, Outer Tube 1, dunnage 3, warning pipe 6, film 8, cloche 7;
Interior conduit 2 is for delivery of fuel gas;
Outer Tube 1 is enclosed within the outside of interior conduit 2 by the dunnage 3 being arranged on interior conduit 2 two ends; The inwall of Outer Tube 1, the outer wall of interior conduit 2 and dunnage 3 form enclosed space 9, are full of nitrogen in enclosed space 9;
Warning pipe 6 is vertically installed in the outside of Outer Tube 1 near one end of dunnage 3, and warning pipe 6 is communicated with enclosed space 9; Warning pipe 6 is divided into cavity of resorption 4 and epicoele 5, the powder of the solid redness of epicoele 5 by the film 8 being arranged at middle part;
It is outside that transparent cloche 7 is arranged at warning pipe 6.
Outer Tube 1 arranged outside has corrosion-resistant coating.Cloche 7 and Outer Tube are welded to connect.Warning pipe 6 is positioned in the middle part of cloche 7.Cloche 7 inwall is provided with rough projection.
It should be noted that, the pressure reduction that in the utility model, film 8 bears is 0.1-0.2MPa, when exceeding this scope, should break.Therefore, when the pressure difference of warning pipe 6 epicoele and cavity of resorption maintains 0.1-0.2MPa, pipeline is considered as normal.
Below principle of the present utility model is described: the nitrogen being first full of certain pressure in enclosed space 9, the pressure of this alarm pipe 6 cavity of resorption equals the pressure of nitrogen, when interior conduit 2 occurs to leak, cause the pressure increase in enclosed space 9, the pressure difference that film bears also increases thereupon.When film can not bear this pressure difference, break, then the red powder of placing in warning pipe 6 epicoele sprays cloche 7 because of gas from bottom to top.It is red that monitor staff finds that cloche 7 is dyed to, and occurred leakage accident with regard to witness tube road, needs to keep in repair.
The utility model provides a kind of anti-leak natural gas line for pipe network monitor system, when generation gas leakage, maintenance man can position it easily, with tradition by compared with electronic monitoring means, has that cost is low, the life-span long, broad-spectrum advantage.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
