The utility model further improves 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 bimetallic tube.
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 is used for stopping that interior Polyurethane Wearing Ring is out of shape laterally, and outer baffle ring is used for stopping that outer Polyurethane Wearing Ring is out of shape to the inside, to ensure the effect of sealing.
On described inside and outside clamping flange ring and supported flange ring, be 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 and the inside and outside baffle ring of supported flange ring inner side on inside and outside clamping 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 inner tube periphery is provided with trapezoidal groove.
When the quick maintenance device of Underwater Two-layer oil transport pipeline of the present utility model uses, described inside and outside urethane seal ring by the space sealing between the inner and outer pipe of bimetallic tube, keeps the double layer construction of inner tube oil transportation outer tube insulation under the effect of turnbuckle and compression slips.Turnbuckle and compression slips are also by inside and outside clamping flange ring tension, and the slips of the inner tube periphery that is located at bimetallic tube is tightly fixed on inner tube periphery by outer, interior clamping flange ring.Because pipeline is double-skin duct, necessity outer tube excision in the time that inner tube is keeped in repair, inner tube is fixed rear outer tube and can not be recovered, and occurs two broken ends.Need to the utility model be installed at this broken end place, utilize this device that the space of the inner and outer pipes of other parts is separated, recycle this device suppress assembly and drain assembly squeezes out bimetallic tube inside ponding, to ensure the heat insulating ability of bimetallic tube.
The utlity model has structure tight rationally, it is convenient to install, easy to use, adjusts flexibly, makes the installation in double-layer oil delivery pipe road, maintenance and repair very convenient, and high efficient and reliable has improved the safety guarantee of Underwater Two-layer oil transport pipeline greatly.
