Pipe and insulator steel bushing, described interior steel pipe one end are tightly connected insulator steel bushing, and the other end is tightly connected pipe shaft.
The insulating joint also includes outer rim, and the outer rim is connected to one end of interior fastener for connection pipe shaft, the pipe shaft
End part seal be folded between interior steel pipe and outer rim.
The end of the pipe shaft is folded between outer rim and interior steel pipe by y-type seal ring.
One end of the interior fastener for connection outer rim is provided with the thread segment with the cooperation of pipe shaft.
The insulator steel bushing sealing shroud is located at interior steel pipe periphery.
Sealed between the insulator steel bushing and interior steel pipe by insulating seal and insulated enclosure circle.
The pipe shaft is sequentially provided with interior steel wire, intermediate layer and outer steel wire from inside to outside, and the intermediate layer is from inside to outside successively
Include tensile layer, sealant and wear-resistant layer.
The utility model connects the pipe shaft and flange of composite soft tube by insulating joint, and the insulating joint can avoid compound
Stray electrical current caused by different potentials between flexible pipe pipe shaft and flange be present, and then avoid the fire triggered by stray electrical current
Calamity is dangerous, and the insulating joint can also avoid the fire hazard caused by electrostatic, ensure that the security of liquid handling operation.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
For the technology contents of detailed the utility model, architectural feature, institute's reached purpose and effect, embodiment will be enumerated below
And Figure of description is coordinated to be described in detail.
Shown in reference picture 1, the utility model discloses a kind of insulated compound flexible pipe, and it includes pipe shaft 20 and insulating joint
30, the insulating joint 30 includes interior steel pipe 2, outer rim 4 and insulator steel bushing 8, wherein, interior one end of steel pipe 2 is tightly connected insulation
Body steel bushing 8, other end connection outer rim 4.One end that interior steel pipe 2 connects outer rim 4 is provided with the thread segment coordinated with pipe shaft 20, on
The end part seal for stating pipe shaft 20 is folded between interior steel pipe 2 and outer rim 4.
Insulated compound flexible pipe is typically connected by flange 1 with other oil-stocking equipments or container, and the utility model is compound
An insulating joint 30 is set up between the pipe shaft 20 and flange 1 of flexible pipe, avoids stray electrical caused by electrostatic or different potentials
The triggered fire hazard of stream, it ensure that the security of the liquid handling operation relevant with the device such as ship.
The medial surface of above-mentioned interior steel pipe 2 could be arranged to insulating barrier, further ensure the exhausted of interior steel pipe 2 and its interior liquid
Edge.
Above-mentioned pipe shaft 20 is sequentially provided with interior steel wire 6, intermediate layer 5 and outer steel wire 7 from inside to outside, wherein, intermediate layer 5 is by introversion
Tensile layer, sealant and wear-resistant layer are included successively outside.The end of the pipe shaft 20 can be folded in outer rim 4 by y-type seal ring 3
Between interior steel pipe 2, the thread segment of the interior steel wire 6 of the end of pipe shaft 20 and interior steel pipe 2 coordinates, and the extension of intermediate layer 5 is interposed in Y
Between two branchs of type sealing ring 3.The y-type seal ring 3 ensure that the sealing between the end of pipe shaft 20 and interior steel pipe 2,
The sealing between the end of pipe shaft 20 and outer rim 4 is ensure that, further ensures that the liquid in pipe shaft 20 will not be from interior steel pipe
2nd, the junction leakage between pipe shaft 20 and outer rim 4.
The above-mentioned one end adpting flange 1 of insulator steel bushing 8, other end sealing shroud are located at the interior periphery of steel pipe 2, insulator steel bushing 8
It can be sealed between interior steel pipe 2 by insulating seal 9 and insulated ring 10.Insulating seal 9 and insulated ring 10 are being protected
Sealing between steel pipe 2 and insulator steel bushing 8 in card, avoids the liquid in interior steel pipe 2 from leaking it from junction between the two
Outside, it also effectively ensure that the insulating properties of the insulating joint 30.
It is of the present utility model it is critical that the utility model pass through insulating joint 30 connect composite soft tube pipe shaft 20 and method
Orchid 1, the insulating joint 30 can avoid stray electrical caused by different potentials between composite soft tube pipe shaft 20 and flange 1 being present
