Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention includes at least one connector unit A, each connector unit A comprises a connecting cylinder 1, what be bolted to connection a tubular at the top of connecting cylinder 1 decides ring 2, surely encircle 2 outside by bearing 3 and seal ring 4 rotating ring 5 that is rotationally connected, deciding after the connection forms a ring cavity 6 between ring 2 and the rotating ring 5.At the inwall that encircles 2 surely the one fixed tube joint 7 that is communicated with ring cavity 6 is set, the outlet end of fixed tube joint 7 is located in downwards in the connecting cylinder 1, and its end is provided with a flange 8, is used to connect the pipeline in static place.For easy to connect, on the wall of connecting cylinder 1, offer one or more gathering holes 9, can carry out pipeline by gathering hole 9 and connect.But the rotating pipe joint 10 that a follow-up ring rotates together is set outside the wall of rotating ring 5, and an end of rotating pipe joint 10 connects ring cavity 4, and the other end connects the pipeline of single point mooring unit.
In the foregoing description, be connected rotating ring 5 and encircle the bearing that bearing 3 between 2 can adopt prior art surely, " three row's roller type floating bearings " such as sky, Xuzhou dragon pivoting support Co., Ltd produces is provided with protective housing 11 in the outside of bearing 3, enters with waterproof or foreign matter.The seal ring 4 that is connected rotating ring 5 and encircles surely between 2 also can adopt prior art, such as be symmetrical arranged the seal ring 4 (as shown in Figure 3) that the twice top has v-seal lip 12 joint upper and lower, in the four road seal rings 4, near inner twice are primary seal circles 4, twice near the outer end are reserve seal rings, and they just afforded the important task of sealing after the proximal seal circle loses efficacy for some reason.Seal ring 4 is contained in the seal groove of rotating ring 5 inwalls, the sealing lip at seal ring 4 tops 12 with encircle the 2 outer surfaces sealing pair that partners surely, assurance device is trouble free service under design conditions.With seal ring 4 be connected decide ring 2 outer rings and can be provided with and adopt built-up welding and form a coating, reach wear-resistant and corrosion resistant purpose.Per pass seal ring 4 should have its leak detecting device mutually, such as: be furnished with leak detection pipeline radially in rotating ring 5, these pipelines have threaded coupling 14 to be communicated with drain container at rotating ring 5 cylindrical places, and this road seal ring 4 then can be found immediately if any leaking.At the top of encircling 2 surely a connection piece 14 can also be set, in order to connect the equipment of other needs.
As Fig. 4, shown in Figure 5, liquid rotating joint of the present invention can be connector unit A, B, the C that is stacked together by a plurality of ..., form a passage jointly, in same passage, just multiple pipeline can be set like this.Such as: decide ring 2 tops with what the connecting cylinder 1 of first connector unit A was connected second connector unit B, decide ring 2 tops with what the connecting cylinder 1 of second connector unit B was connected second connector unit C, with the fixed tube joint 7 of three connector unit A, B, the C angle that staggers mutually, being arranged in the same passage, and do not influence adjacent fixed pipe joint 7.The connecting cylinder 1 of nethermost connector unit C is connected on the pedestal 15, and uppermost connector unit A decides ring 2 tops link 14 can be set, to connect miscellaneous equipment.
The present invention can be provided with three or four pipelines in a passage, be two such as three liquid lines and be used for conveying crude oil or well stream (one of them can be used as standby), and one is used to carry water filling water etc.
