Description
Technical field
The utility model is related to a kind of underwater connector, and in particular to a kind of underwater connector.
Background technology
Underwater connector is important connection equipment between underwater production facility, be mainly used in jumper pipe and subsea manifold,
Subsea production tree, between subsea production tree and underwater well head, and connection between marine riser and subsea blowout preventer etc..
In with high investment, excessive risk deepwater oil-gas development, underwater connector is to ensureing that deep water hydrocarbon safety in production is significant.
At present, widely used underwater connector has jack catchs type connector and hydraulic pressure lock block type connector.
Jack catchs type connector is will to need the bridging tube end of connection（Upper hub）With production tree or the interface of manifold（Lower hub
Seat）Flange be buckled together with 10 to 20 identical claws, using hydraulic power drive drive sleeve（Driving ring）Along claw
Outside glides, and will surround all claw bandings of a circumference, realizes locking.The connector advantage is non-threaded connection, reliably
Property it is high.It is disadvantageous in that the installation tool, it is necessary to complex.
Hydraulic pressure lock block type connector is generally the H4 connectors of Vetco Gray companies and the DX type hydraulic pressure of Dril-Quip companies
Connector.
H4 lock block types connector realizes unblock using multigroup hydraulic cylinder combination drive mechanism or locked that bottom is designed with guiding
Mechanism, which ensure that, is connected equipment automatic centering with bottom.When being connected between facilities and equipments, piston driving driving ring passes through liquid
Force feed is moved down, and driving ring extruding locking block makes it be engaged with the teeth groove of connected piece, to realize between equipment interface
Linkage function.On the contrary, when needing to implement normal disengagement or promptly disengage, hydraulic oil passes through in remote control driving hydraulic cylinder
Piston upwards, make driving ring depart from the closing piece field of conjugate action, complete to unlock and ensure to disengage with connector.
The work of DX types hydraulic connector includes locking process, releasing process and secondary unlocking process.The connector closing piece
On be designed with skewed slot, when hydraulic pressure drives driving ring to be moved, driving ring is driven by the attachment means that can be slided on skewed slot
Closing piece is engaged or departed from.Secondary unlocking function is Redundancy Design, it is ensured that in case of emergency or once unlock the feelings of failure
The secondary emergent unblock piston of auxiliary promotes unblock piston upwards under condition, forces closing piece to be disengaged at lower attachment, completes
It is vertically connected with the separation between equipment.
H4 and DX connectors common trait is to drive the upper and lower motion of piston by hydraulic oil, closing piece is set with being connected
Standby engagement is separated to realize the locking or unblock of equipment, and this 2 kinds of connectors are respectively provided with that compact conformation, bearing capacity be strong, property
Can reliably it wait.It is disadvantageous in that, H4 connectors have asking for many fluid cylinder co-ordination poor synchronizations due to taking multi-cylinder to drive
Topic；DX connectors entirety fluid cylinder is heavier, and structure is complex.
For a long time, by underwater connector research and development and manufacturing technology are monopolized by foreign oil equipment company, China
Offshore and gas development construction can only rely on equipment importation, and the domestic research to underwater connector technology is still immature.Therefore, independently
Research and development deep water underwater connector supported with to accelerate China's deepwater oil-gas development offers technology and equipment be we urgently to be resolved hurrily
Business.
