Abstract
The utility model discloses a natural gas pipeline compensator in the technical field of pipeline connecting device, which comprises a stainless steel waveform pipe, an integral flange and a pulling rod nut. A section of connecting pipe is welded at the two ends of the waveform pipe; a section of draft tube is welded in the cavity of the connecting pipe; the connecting pipe then is welded with the two integral flanges; adjusting nut and screw stem are adopted to adjust the length of the waveform pipe. As a compensator directly arranged in the natural gas pipeline, this utility model can be used to compensate the coaxial flexibility of the natural gas pipe due to temperature change and the installation difference resulted during the installation of the pipeline, valve and other pipe elements. It has the advantages of small volume, great compensation amount, high safety coefficient and convenient installation.
Description
Technical field
The utility model belongs to assembling pipe joint, particularly a kind of natural gas line compensator.
Background technique
Existing pipe joint all connects firmly, does not have stretchability, during installation, if the connecting tube cutoff length is improper, can only cut suitable length again, causes waste, or connects by force, and joint is fragile or seal bad.Be connected with stretchability with singel-ply bellows, but because of the ripple tube wall is thin, easy stretched crack causes defect such as leakage, may cause accident to take place, cause any property loss or life safety.
Summary of the invention
The purpose of this utility model provides a kind of natural gas line compensator, it is characterized in that bellows 3 two ends are respectively welded one section and taken over 6, take over 6 and weld with two integral (type) flanges 1 respectively again, in four jiaos of otic placode holes of integral (type) flange 1, respectively wear a screw rod 5, fixing by adjusting nut 2; Take over one section guide shell 4 of inner chamber welding of 6 at one section of bellows 3 two ends.
The internal diameter cunning of the external diameter of described guide shell and bellows 3 is joined, and has only an end and take over 6 welding.
Described bellows is two-layer at least structure.
The thickness of described otic placode is consistent with integral (type) flange.
The beneficial effects of the utility model are that the natural gas line compensator is a kind of compensator that is directly installed among the natural gas line, are used to compensate the alignment error that axial stretching that natural gas line produces owing to temperature variation and pipeline produce with pipe fittings such as valves when mounted.It is little to have volume, and compensation rate is big, and the safety coefficient height is convenient to characteristics such as installation.Be specifically designed among the conveyance conduit that rock gas is a medium.Critical component bellows in the rock gas dedicated compensator is bilayer or multi-layer structure, can adapt to the seal request of any pipeline.And, more significantly improved leakage prevention capability again owing to be multi-layer structure, be that the pipeline operation is more safe and reliable.Flange and otic placode are processed into overall structure, and the thickness of otic placode and the consistency of thickness of flange have improved the flex resistance of otic placode greatly.Can guarantee not pulled during to limit position, thereby the Security of whole pipe network operation is improved greatly in its work.Rock gas dedicated compensator Applicable temperature-40 in particular cases can reach 350 ℃ ℃ to 150 ℃.Guarantee that medium is not revealed in the pipe.
Description of drawings
Fig. 1 is a natural gas line compensator structure schematic representation.
Fig. 2 is the side view of Fig. 1.
Embodiment
The utility model provides a kind of natural gas line compensator.In Fig. 1, the natural gas line compensator structure schematic representation shown in Figure 2, respectively weld one section at bellows 3 two ends and take over 6, take over 6 more respectively with 1 welding of two integral (type) flanges, in four jiaos of otic placode holes of integral (type) flange 1, respectively wear a screw rod 5, fixing by adjusting nut 2; Take over one section guide shell 4 of inner chamber welding of 6 at one section of bellows 3 two ends.The internal diameter cunning of the external diameter of described guide shell and bellows 3 is joined, and have only an end and take over 6 welding, like this when pipe laying, when regulating the length of bellows 3 with adjusting nut 2, can not cause 3 bendings of line pipe, be not easy to crack the seal request that can adapt to any pipeline, and again owing to be multi-layer structure, more significantly having improved leakage prevention capability, is that the pipeline operation is more safe and reliable.Flange and otic placode are processed into overall structure, and the thickness of otic placode and the consistency of thickness of flange have improved the flex resistance of otic placode greatly.Can guarantee not pulled during to limit position, thereby the Security of whole pipe network operation is improved greatly in its work.
