Background technology
At present in deep sea drilling work progress, pouring valve is to one of capital equipment that drilling equipment and pipeline are protected, range of application is very extensive, but presently used pouring valve is in concrete use, what presently used marine riser pouring valve structurally often adopted is shift sleeve structure, and the hatch door of marine riser is slidably mounted on marine riser body interior, thus cause production technology relative complex, device structure is complicated heavy, and be in operation and also very easily normally open and closed because the foreign material such as mud in marine riser pouring valve affect marine riser hatch door, stable equipment operation is poor, simultaneously, the control mode of current marine riser pouring valve also mainly to rely on valve body equalizing valve external and internal pressure difference as control drive singal, realize controlling pouring valve, in use find, once equalizing valve because of the blocking of the foreign material such as mud impaired after, pouring valve then can be caused to control to lose efficacy, simultaneously when equalizing valve external and internal pressure difference is less, then also can cause and control to lose efficacy, thus cause the operational reliability of pouring valve poor further, for this problem, in the urgent need to developing a kind of novel marine riser pouring valve equipment, with the needs that satisfied reality uses.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of novel sea offshore boring island sleeve type marine riser pouring valve, this new structural design is reasonable, structure is simple, easy to use, operation energy consumption is cheap, fault-resistant ability is strong, good operation stability, thus improve equipment reliability of operation and stability on the one hand, extend application life, effectively solve the pouring valve control corresponding speed caused because equalizing valve pressure differential crosses in traditional control system on the other hand slow, perform the drawback that precision is low, thus greatly improve the control accuracy of marine riser pouring valve control system, improve operation stability and the accuracy of marine riser pouring valve.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of novel sea offshore boring island sleeve type marine riser pouring valve, comprise marine riser main body, marine riser hatch door, drive oil cylinder, equalizing valve, main control valve, locking-valve, switching valve and accumulator, wherein main control valve, locking-valve, switching valve and accumulator are all positioned on marine riser body outer surface, marine riser hatch door is coated on marine riser lower body part and is slidably connected, marine riser main body and marine riser hatch door coaxially distribute, marine riser main body lateral surface separately establishes the location-plate distributed ringwise, and location-plate and marine riser main body coaxially distribute, marine riser hatch door external surface is uniform at least two engaging lugs separately, oil cylinder is driven to be connected with marine riser main body and marine riser hatch door respectively by location-plate and engaging lug, and drive oil cylinder at least two, and it is uniform around marine riser main body axis, equalizing valve is separately embedded in marine riser main body, main control valve separately by oil pipe respectively with equalizing valve, locking-valve and switching valve are communicated with, switching valve another respectively with locking-valve, accumulator and driving oil cylinder are communicated with, described equalizing valve is separately communicated with locking-valve, main control valve separately establishes RCI, and be communicated with external control hydraulic power source by RCI.
Further, separately Controlling solenoid valve is established between described accumulator and switching valve.
Further, described equalizing valve, main control valve, locking-valve, switching valve all at least two, and with all in parallel between kind valve body.
This new structural design is reasonable, structure is simple, easy to use, operation energy consumption is cheap, fault-resistant ability is strong, good operation stability, thus improve equipment reliability of operation and stability on the one hand, extend application life, effectively solve the pouring valve control corresponding speed caused because equalizing valve pressure differential crosses in traditional control system on the other hand slow, perform the drawback that precision is low, thus greatly improve the control accuracy of marine riser pouring valve control system, improve operation stability and the accuracy of marine riser pouring valve.
