Description
Technical field
The present invention relates to a kind of machinery technology, specifically a kind of device for the installation of Underwater Two-layer oil transport pipeline, maintenance and repair, the quick maintenance device that the leak stopping being specially adapted to Underwater Two-layer oil transport pipeline is repaired.
Background technique
The quick maintenance of Underwater Two-layer oil transport pipeline is a very difficult operation, and the use in double-layer oil delivery pipe road is extremely important and general.Owing to soaking in the seawater for a long time, external pipe is very easy to be corroded and damaged, and then the safety of pipe oil transportation in impact.For a long time, when after the breakage of double-layer oil delivery pipe road, can only be interrupt oil transportation, block transport pipe, very difficulty carry out the replacing of pipeline.Cause the interruption of producing the long period, cause very large loss to production.And due to damaged pipe change not in time or plugging effect bad, also often cause the leakage of oil, large losses oil, makes seawater pollution, causes very large environmental protection accident and economic loss.Therefore, be necessary very much to propose one rational in infrastructure, easy for installation, change double-layer oil delivery pipe quick, the quick maintenance device of the Underwater Two-layer oil transport pipeline that plugging effect is good.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, propose the quick maintenance device of a kind of Underwater Two-layer oil transport pipeline, this device is provided with plug members and fixed component, and novel structure is quick for installation, flexible adjustment, and shutoff and maintenance effects very good.Not only can use when repairing double-layer oil delivery pipe way, can also use when initial installation double-layer oil delivery pipe way.
The object of the invention is to be achieved through the following technical solutions:
The quick maintenance device of Underwater Two-layer oil transport pipeline, it is characterized in that: be provided with outer clamping flange ring, interior clamping flange ring, the diameter of this interior clamping flange ring is less than the outer tube inner diameter in double-layer oil delivery pipe road, be arranged between inner and outer pipes, the outer circumference diameter of described outer clamping flange ring is greater than the outer tube diameter in double-layer oil delivery pipe road, and this outer clamping flange ring is arranged on the outer tube termination in double-layer oil delivery pipe road; Or the outer circumference diameter of described outer clamping flange ring is less than the inner diameter of the outer tube in double-layer oil delivery pipe road, described inside and outside clamping flange ring is all fixed between the inner and outer pipe in double-layer oil delivery pipe road; Be provided with the slips wrapping in interior pipe periphery between this outer, interior clamping flange ring, slips is clamped on pipe periphery in double-layer oil delivery pipe road from slips both sides by described outer, interior clamping flange ring; Polyurethane Wearing Ring and outer Polyurethane Wearing Ring is in one plane provided with in the outside of described interior clamping flange ring, multiple turnbuckle is provided with between this inside and outside Polyurethane Wearing Ring, this turnbuckle is through described outer clamping flange ring and interior clamping flange ring, the outer end of turnbuckle is fixed on outer clamping flange ring, inner end is threaded with the supported flange ring be arranged on outside inside and outside Polyurethane Wearing Ring, and this turnbuckle and supported flange ring are by inside and outside Polyurethane Wearing Ring and the tension of inside and outside clamping flange ring.
The present invention improves further and the additional project of enforcement is:
The outer side surface of described supported flange ring is narrower than inner side surface, is convenient to enter between double-layer oil delivery pipe road.
The inner side surface of described supported flange ring is provided with a cylindric inner baffle ring and a cylindric outer baffle ring.Inner baffle ring for stopping that interior Polyurethane Wearing Ring is out of shape laterally, outer baffle ring for stopping that outer Polyurethane Wearing Ring is out of shape to the inside, with ensure seal effect.
Described inside and outside clamping flange ring and supported flange ring are provided with one and suppress assembly and a drain assembly, these two assemblies are respectively equipped with a siphunculus, are provided with a sealing rotary interface in the inner end of siphunculus, and the outer end of siphunculus is provided with a valve; Described siphunculus penetrates between the open-work on inside and outside clamping flange ring and the inside and outside baffle ring inside supported flange ring, the sealing rotary sealing joint of described inner end is screwed in the open-work inboard of described supported flange ring, is arranged on the outside of outer clamping flange ring at the valve of the outer end of siphunculus.
The slips inner side surface of described interior pipe periphery is provided with trapezoidal groove.
When the quick maintenance device of Underwater Two-layer oil transport pipeline of the present invention uses, described inside and outside Polyurethane Wearing Ring turnbuckle and compress slips effect under space sealing by managing in double-layer oil delivery pipe road, between outer tube, the double layer construction of pipe oil transportation outer tube insulation in keeping.Turnbuckle and compression slips are also by inside and outside clamping flange ring tension, and the slips being located at pipe periphery in double-layer oil delivery pipe road is tightly fixed on interior pipe periphery by outer, interior clamping flange ring.Because pipeline is double-layer oil delivery pipe way, when interior pipe maintenance, necessity excises outer tube, and interior pipe is fixed rear outer tube and can not be recovered, and occurs two broken ends.Need to install the utility model at this broken end place, utilize this device the spaced apart of the inner and outer pipes of other parts, suppress assembly and the drain assembly that recycle this device squeeze out, inner for double-layer oil delivery pipe road ponding to ensure the heat insulating ability in double-layer oil delivery pipe road.
It is rationally tight that the present invention has structure, and it is convenient to install, easy to use, and flexibly, make the installation in double-layer oil delivery pipe road, maintenance and repair very convenient, high efficient and reliable, substantially increases the safety guarantee of Underwater Two-layer oil transport pipeline in adjustment.
