In described single straight-through liquid in rotation passage, the mode that described rotation pipeline section end and described rotation pipeline section end and described pivoting support all can be with bolts is carried out mechanical type and is connected.
In described single straight-through liquid in rotation passage, sealed by seal ring between described rotation pipeline section end and described fixing pipeline section end.
In described single straight-through liquid in rotation passage, described seal ring is arranged in the groove of described rotation pipeline section end outer wall, the size of described groove designs according to the installation requirement of described seal ring, and then the outer ratio described seal ring being located at described rotation pipeline section end is convenient to processing and control accuracy.
In described single straight-through liquid in rotation passage, described seal ring comprises several Glais rings be evenly arranged;
Leak hunting joint is provided with between adjacent two described Glais rings, and described leak hunting joint extends to outside described fixing pipeline section end, shutoff (only taking off when leaking hunting and detecting) is carried out by plug screw, namely in the circumference of described fixing pipeline section end, several described leak hunting joint is evenly equipped with, realize the timely prevention to seal failure, avoid leaking and cause larger loss.
When using the single straight-through liquid in rotation passage of the utility model, by described connecting panel single for the utility model straight-through liquid in rotation passage utilized and be bolted on the framing member of erection joint on FPSO, distortion and the destruction of oil hose can be reduced.
The single straight-through liquid in rotation passage tool that the utility model is applicable to the outer communication system of spread mooring FPSO has the following advantages:
The utility model adopts technique scheme, by adopting pivoting support as the connection of revolving part, solves rotation and the irregular movement problem of flexible pipe; By adopting the sealing of multilayer Glais ring, single straight-through liquid in rotation passage is made can be effectively applicable to rotary motion and crank motion; By being provided with leakage measuring instrumentation point between seal ring, realize, to the timely prevention of seal failure, avoiding leaking and causing larger loss.The utility model structure is simple, and be convenient to installation, dismounting, safeguard, applicability is strong.
Accompanying drawing explanation
Fig. 1 is the generalized section of the single straight-through liquid in rotation passage of the utility model.
In figure, each mark is as follows:
1 rotates pipeline section end, 2 connecting panels, 3 pivoting supports, 4 seal rings, 5 fixing pipeline section end, 6 leak hunting joints, 7 metal plug screws.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model be confined to following examples.
As shown in Figure 1, be applicable to the generalized section of the single straight-through liquid in rotation passage of the outer communication system of spread mooring FPSO for the utility model, it rotates pipeline section end 1, fixing pipeline section end 5, pivoting support 3 and connecting panel 2.Wherein, rotating pipeline section end 1 adopts bolt to be connected with the inner ring face of pivoting support 3, fixing pipeline section end 5 all adopts bolt to be connected with the face, outer ring of pivoting support 3 with connecting panel 2, and connecting panel 2 is positioned at the same side of pivoting support with rotation pipeline section end 1, and fixing pipeline section end 5 is positioned at the opposite side of pivoting support 3.Rotating pipeline section end 1 extends in the tube chamber of fixing pipeline section end 5, and be sealed and matched by seal ring 4 between rotation pipeline section end 1 and fixing pipeline section end 5, in the utility model, seal ring 4 is Glais ring, and seal ring 4 is arranged in the groove rotated on pipeline section end 5 outer wall, and for being evenly arranged.And being provided with leak hunting joint 6 between adjacent two seal rings 4, leak hunting joint 6 extends to outside fixing pipeline section end 5, namely in the circumference of fixing pipeline section end 5, is evenly equipped with several leak hunting joint 6, realizes, to the timely prevention of seal failure, avoiding leaking and causing larger loss.Leak hunting joint 6 metal plug screw 7 carries out shutoff, takes off when needs do Leak Detection.
