Description
Technical field
The utility model relates to a kind of fuel gas transportation pipeline, is specifically related to a kind of PE composite fuel gas pipe.
Background technique
At present, the combustion gas such as rock gas, coal gas, liquefied petroleum gas (LPG) has been widely used in resident living and industrial production.Along with the continuous progress of new material technology, novel PE fuel tube has that density is low, good fluidity, tightness are good, chemical resistance is strong, the aspect advantages such as simple and reliable, easy processing and installation of constructing, progressively instead of traditional metallic gas transport pipe, fuel gas transmission is used widely.But, due to restrictions such as PE fuel tube material, structures, there are some shortcomings in PE fuel tube: impact resistance is poor, compressive strength is not high, be subject to climate temperature impact, reveal cannot Timeliness coverage, not easily detection of leaks point, be subject to by the insect such as termite moth erosion, not sun-resistant etc.
China's application number is the patent of 2014201627010, a kind of PE fuel tube is disclosed, the inside liner of described tubing adopts flame retardant rubber to make, inside liner is coated with metal net layer, be provided with outer layer of polyethene outside metal net layer, be provided with insect repellent outside outer layer of polyethene, pipe end is provided with connecting groove, connecting groove is connected with metal net layer by plain conductor, and connecting groove connects alarm by connecting wire.Although this model utility arranges metal net layer, insect repellent and alarm, improve the anti-pressure ability of body, prevent insect eat into erosion while improve safety precaution, but have the following disadvantages: one, PE fuel tube is subject to climate temperature impact with not sun-resistant, and this tubing does not arrange the protective layers such as relevant heat insulation, insulation, body is easily out of shape with aging, affects working life; Its two, tubing only arranges alarm in end, conveniently detects relevant configuration when not arranging leakage, not easily checks gas leakage point, maintenance difficulty; In addition, tubing only arranges flame retardant rubber internal layer, does not arrange associated closure containment measures, and Safety performance is not high.
Model utility content
For the deficiencies in the prior art, the utility model provides that a kind of compressive strength is high, Safety performance good, the PE composite fuel gas pipe of long service life.
In order to achieve the above object, the technological scheme that the utility model is taked is:
A kind of PE composite fuel gas pipe, comprise body, described body is lumarith, basic unit, combustion gas special (purpose) rubber layer from outside to inside; Described lumarith is made up of matrix resin and modified additive material; Described basic unit comprises PE skin, wire netting sandwich layer, PE internal layer, many axially extend to body two ends wire along body is provided with between PE skin and wire netting sandwich layer, described wire is uniformly distributed in the circumferential outer surface of wire netting sandwich layer, and wire one end is connected with the detector alarm of body end; Described combustion gas special (purpose) rubber layer outer surface is laid with latex layer.
As optimal technical scheme, in order to prevent fuel tube by the aging and bending deflection caused at sunshine and ambient temperature, described PE skin and PE internal layer are all be made up of thermoplastic elastomer polythene material.
As optimal technical scheme, in order to improve the crushing resistance of body, avoid body to be subject to greater impact power and bending deflection or break, described combustion gas special (purpose) rubber layer is by making by pliable and tough telescopic material.
The beneficial effect that the utility model has:
1, body is provided with detector alarm, wire, in time the convenient leak point detecting body while reflection body leakage situation.
2, body is provided with latex layer, improves the tightness of body in case stopping leak reveals the security incident caused, improves the Safety performance of body.
3, select thermoplastic elastomer polythene material, effectively prevent body by the aging and bending deflection caused at sunshine and ambient temperature, improve the working life of body.
4, be provided with lumarith, effectively avoid body by the damage such as termite, mouse, increase the service life while both improving Safety performance.
5, pipe structure simple, be easy to manufacture, cost is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section view of the present utility model;
Drawing reference numeral: 1, body, 2, lumarith, 3, basic unit, 3-1, PE are outer, 3-2, wire netting sandwich layer, 3-3, PE internal layer, 3-4, wire, and 4, combustion gas special (purpose) rubber layer, 4-1, latex layer, 5, detector alarm.
Embodiment
As depicted in figs. 1 and 2, propose specific embodiment of the utility model, a kind of PE composite fuel gas pipe, comprises body 1, and described body 1 is lumarith 2, basic unit 3, combustion gas special (purpose) rubber layer 4 from outside to inside; Described lumarith 2 is made up of matrix resin and modified additive material.
As shown in Figure 1, described basic unit 3 comprises PE outer 3-1, wire netting sandwich layer 3-2, PE internal layer 3-3, many axially extend to body 1 two ends wire 3-4 along body 1 is provided with between the outer 3-1 and wire netting sandwich layer 3-2 of PE, described wire 3-4 is uniformly distributed in the circumferential outer surface of wire netting sandwich layer 3-2, and wire 3-4 mono-end is connected with the detector alarm 5 of body 1 end; The present embodiment preferably arranges PE outer 3-1 and PE internal layer 3-3 and is made up of thermoplastic elastomer polythene material, and fuel tube can be prevented by the aging and bending deflection caused at sunshine and ambient temperature.
As depicted in figs. 1 and 2, described combustion gas special (purpose) rubber layer 4 outer surface is laid with latex layer 4-1, it is by making by pliable and tough telescopic material that the present embodiment preferably arranges combustion gas special (purpose) rubber layer 4, when fuel tube basic unit 3 can be avoided to be subject to greater impact power, having flexible combustion gas special (purpose) rubber layer 4 can provide buffering and avoid body 1 bending deflection or break.
When fuel tube uses: when fuel tube is worn or ftractures, combustion gas is once reveal contacting metal sandwich layer 3-2, and the detector alarm 5 of body 1 end reflects warning in time, avoids the security incident generations such as poisoning; Can detect body 1 leak point by many one metal wires 3-4 is convenient, maintenance saves time easy simultaneously.
