Description
Technical field
The utility model relates to natural gas pipeline field of engineering technology, and especially a kind of natural gas pipeline ripple connectsConnect device.
Background technology
Existing natural gas tube pipe connecting adopts hard connection mostly, if the cutting of tube connector length is inaccurate, justNeed to again cut suitable length, cause waste; Or jointing by force, can cause joint to damage like thisBad or seal badly, cause pipeline internal medium to be revealed causing causing any property loss security incident, serious alsoCan life-threatening safety. In recent years also occurred that using compensation device connects, but existing connector welds on flangeJournal stirrup and tube connector, tube connector again with bellows-welding, there is the journal stirrup insufficient strength of welding in this series products,Easily break, add to take over and be welded into highly, flange, by tube connector and bellows-welding, has increased the weldering of productRoad, the increase of welding bead certainly will affect the security performance of product comparatively speaking, also increases in the time producing product simultaneouslyHuman cost and material cost.
Utility model content
The utility model embodiment provides a kind of natural gas pipeline corrugated connector, for solving existing companyConnect the too much technological deficiency of welding bead in device.
In order to address the above problem, the utility model provides a kind of natural gas pipeline corrugated connector, comprises rippleLine pipe, described bellows two ends are directly welded with respectively integrally-built adpting flange, one of described bellowsThe inner radius of end is welded with stainless steel diversion cylinder, and the journal stirrup of described adpting flange is provided with mounting condition screw rodInstalling hole, fixes by screw rod and adjusting nut between two described adpting flanges.
The natural gas pipeline corrugated connector that the utility model embodiment provides also has following technical characterictic:
Further, described guide shell is welded on the inlet end of described bellows, the external diameter of described guide shell withThe internal diameter of described bellows is slidably matched.
Further, the two ends of described bellows have vertical section, one end of described guide shell and described rippleOne end welding of pipe, the other end of described guide shell is another along extending axially to described bellows of described bellowsVertical section of one end.
Further, the one end being slidably matched at described guide shell and described bellows, outside described mozzleBetween the internal diameter of vertical section of footpath and described bellows, be provided with sealing ring.
Further, described adpting flange is overall sheet material excision forming, described journal stirrup and described adpting flangeBody thickness is identical.
Further, described bellows adopts thin wall multi-layer structure, and described thin wall multi-layer structure is at least 3 layers,Described thin wall multi-layer structure adopts stainless steel material.
The utlity model has following beneficial effect: by adopting integrally-built adpting flange, bellows twoHold direct and adpting flange welding, reduced the welding bead in product, sealing and the safety of connector is providedProperty; One end of inside diameter of bel is welded with stainless steel diversion cylinder, and the gas componant in reduction natural gas is to connectingThe corrosion of device, has improved the security performance of product.
Brief description of the drawings
Fig. 1 is the structural representation of the natural gas pipeline corrugated connector of the utility model embodiment;
Fig. 2 is the structural representation of the adpting flange in Fig. 1.
Detailed description of the invention
Hereinafter also describe the utility model in detail with reference to accompanying drawing in conjunction with the embodiments. It should be noted that,In the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.
In an embodiment of natural gas pipeline corrugated connector of the present utility model as shown in Figure 1, this skyFuel gas pipeline corrugated connector, comprises bellows 2, and bellows 2 two ends are directly welded with respectively overall structureAdpting flange 1, the inner radius of one end of bellows 2 is welded with stainless steel diversion cylinder 3, adpting flange 1Journal stirrup be provided with between 12, two adpting flanges 1 of installing hole of mounting condition screw rod 4 by screw rod 4 HesAdjusting nut 5 is fixing. Natural gas pipeline corrugated connector in this embodiment, integrally-built by adoptingAdpting flange, bellows two ends directly with adpting flange welding, reduced the welding bead in product, company is providedConnect sealing and the security of device; One end of inside diameter of bel is welded with stainless steel diversion cylinder, reduces natural gasIn the corrosion of gas componant to connector, improved the security performance of product.
The natural gas pipeline corrugated connector that above-described embodiment provides also has following technical characterictic: guide shell 3Be welded on the inlet end of bellows 2, the internal diameter of the external diameter of guide shell 3 and bellows 2 is slidably matched, thusCan be regulating when connector free axis to activity, and can not cause bellows 2 flexural deformations, improve and connectedConnect the perpendicularity of device, better adapt to seal for pipe joints requirement. Further, the two ends of bellows 2 have verticallySection, weld one end of one end of guide shell 3 and bellows 2, and the other end of guide shell 3 is along bellows 2Extend axially to vertical section of bellows 2 other ends, make thus gas enter and lead by the inlet end of connectorStream cylinder 3 is rear directly discharges by guide shell 3, avoids gas to contact with bellows and causes bellows corrosion. ?One end that guide shell 3 and bellows 2 are slidably matched, the external diameter of mozzle 3 and bellows 2 vertical sectionBetween internal diameter, be provided with sealing ring, avoid thus gas to contact with bellows 2 and cause bellows corrosion, improve and produceThe security of product. Adpting flange 1 is overall sheet material excision forming, journal stirrup 14 and adpting flange body thickness phaseTogether, strengthen thus the intensity of journal stirrup, ensured not to be pulled off in its work, improved the use of connectorLife-span. Bellows 2 adopts thin wall multi-layer structure, and thin wall multi-layer structure is at least 3 layers, thin wall multi-layer structureAdopt stainless steel material, reduced thus the rigidity of connector, improved significantly the leakproof energy of connectorPower, makes pipeline operation more safe and reliable. Natural gas pipeline corrugated connector in this embodiment, when naturalFlexible can directly the tune with the realization of pipeline corrugated connector of axial displacement that air pipe produces due to variations in temperatureWhole, when pipeline is at mounted valve or other pipe fittings and while having produced alignment error, can adjust by adjusting nutThe length of joint connector compensates alignment error, has compensation rate large, and safety coefficient is high, is convenient to peaceThe features such as dress.
Finally it should be noted that: above embodiment is only in order to the technical solution of the utility model to be described, but not rightIts restriction; Although the utility model is had been described in detail with reference to previous embodiment, this area commonTechnical staff is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified,Or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make corresponding skillThe essence of art scheme departs from the spirit and scope of the each embodiment technical scheme of the utility model.
