Description of drawings
Fig. 1 be the utility model critical piece main sectional view.
The figure number explanation:
Flange-1, mark post-2, outer cylinder body-3, annular piston-5, auxiliary piston-9, base-11, metallic packing ring-12, latch segment-14, well head head or axle-15, sealing 4,6,7,8,10,13.
The specific embodiment
As shown in drawings, the hydraulically powered connector of a kind of adaptation ocean deepwater operation, it mainly is made of flange 1, mark post 2, outer cylinder body 3, annular piston 5, auxiliary piston 9, base 11, metallic packing ring 12, locking block 14 and sealing component such as (4,6,7,8,10,13).Annular piston 5 is positioned at the hydraulic cavities that outer cylinder body 3, base 11, locking block 14, flange 1 surround for hydraulic piston and annular piston 5, and annular piston 5 adopts the taper seat with self-locking performance with locking block 14 contact surfaces.Flange 1 exterior bottom is connected with outer cylinder body 3, outer cylinder body 3 bottoms are connected with base 11, base 11 is that round table-like structure and locking block 14 are positioned at the round platform top, well head head or axle 15 are set on base 11 centers, the boss of flange 1 inboard leans locking block 14 upper surfaces, and flange 1 medial surface is connected with well head head or axle 15 upper surfaces by metallic packing ring 12 simultaneously.Auxiliary piston 9 also is housed below annular piston 5, and auxiliary piston 9 is " L " shape structure.Annular piston 5 adopts annular monolithic or a plurality of independently oil cylinder.At annular piston 5 mark post 2 that locking or disengagement for connector provide visual effect is housed.Locking block 14 is made up of the fritter of a plurality of annular spread, is connected by spring between piece and the piece.Locking block 14 adopts the teeth groove engaging structure with well head head or axle 15, is rectangle or triangle or alternate manner.
This hydraulic connector adopts hydraulic-driven, top is that flange 1 connects, it is to be used for meshing with the appropriate section of connector locking piece that four alveolus are arranged on well head head or axle 15 outer circumference surfaces, all adopt bolt to be connected between urceolus 3 and flange 1 and the base 11, formed the external structure of connector, annular piston 5 is housed in their inside, auxiliary piston 9 and locking block 14, this connector has three hydraulic circuits, is respectively locking liquid road, throws off liquid road and auxiliary liquid road.(annotate: locking loop oil closed cavity is made up of outer cylinder body 3, annular piston 5 and joint ring 4,7, throw off the loop oil closed cavity and be made up of outer cylinder body 3, annular piston 5, auxiliary piston 9 and joint ring 8,7, the subsidiary loop oil closed cavity is made up of outer cylinder body 3, auxiliary piston 9, base 11 and joint ring 8,10).In the time of in working order, locking liquid road just is injected into hydraulic oil, drives annular piston 7 then and moves downward, extruding by the inclined-plane promotes to lock radially inwardly motion of block 14, with the alveolar surface engagement, then well head head or axle and connector just are locked together, and have guaranteed normal duty; In a single day if run into emergency at sea in the operation process, such as when in construction, running into typhoon and need withdraw, just need connector can in time throw off well head head or axle, reclaim, throw off the liquid road and mainly realize this function, there is hydraulic oil to inject in case throw off the liquid road, annular piston 5 just moves upward under the promotion of hydraulic oil, stopped squeezing action to locking block 14, and locking block 14 is not an integral body, it is made up of the fritter of many annular spread, be connected by spring between piece and the piece, when annular piston 5 has stopped relying on the restoring force of spring to locking the squeezing action of block 14, lock the teeth groove that block 14 is just thrown off well head head or axle 15; If move on to suitable position not but the hydraulic coupling that joint ring 7,8 lost efficacy or annular piston 5 is subjected to is too little, at this moment just require immediately to auxiliary liquid road fuel feeding, and the hydraulic coupling that requires auxiliary liquid road will be far longer than the hydraulic coupling of throwing off the liquid road, hydraulic coupling promotes annular piston 5 again by auxiliary piston 9 and moves upward, so not working at ordinary times in auxiliary liquid road, just is used in the emergency.
