Description
Technical field
The utility model relates to a kind of shoe spray flushing system.
Background technology
Self-elevating drilling platform is when soft sea bed carries out drilling operation, and shoe spud leg inevitably will embed in the silt in seabed, shallow then several meters, deeply then reaches twenties meters.Be displaced to other region job when this operation is finished, need to carry out pile pulling operation.Need to carry out punching to shoe during pile pulling to sweep, to overcome the absorption affinity on stratum and to be beneficial to pile pulling, in this operation process, find to there are some drawbacks, rushing stake plug valve is worm gear type, and switch needs the time long; Rush stake hose length and only have 8 meters, need frequently to dismantle from spud leg, greatly waste the time; There is no pressure relief valve and pipeline, the time nature relieving pressure that dismounting pipeline needs etc. are longer; Line size is excessive to be caused overweight, needs a large amount of manpowers to carry.These drawbacks reduce work limitation, waste a large amount of manpowers, add potential safety hazard.
Utility model content
The utility model provides a kind of shoe to spray flushing system, comprise inlet line 1 and connecting hose 6, it is characterized in that: also comprise imported valve 2, pressure release flexible pipe 3, pressure relief valve 4, flexible pipe connect union 5 be connected union 7 with spud leg, the port of export of wherein said inlet line 1 connects the arrival end of imported valve 2, the port of export of described imported valve 2 connects pressure relief valve 4 respectively arrival end by tee branch is connected union 5 with flexible pipe, the arrival end of described connecting hose 6 is connected union 5 and connects with flexible pipe, the port of export of connecting hose 6 is connected union 7 and connects with spud leg; The port of export of described pressure relief valve 4 connects pressure release flexible pipe 3.
In an embodiment of the present utility model, described connecting hose 6 for length be greater than 8 meters and the flexible pipe of less than 20 meters.
In an embodiment of the present utility model, the arrival end of described inlet line 1 connects water under high pressure or gases at high pressure feedway.
In an embodiment of the present utility model, described spud leg is connected union 7 and is connected with the screwed hole on spud leg by a crossover sub.
The utility model tool has the following advantages:
The utility model provides pressure fluid or gas to go directly shoe bottom when carrying out pile pulling operation, to destroy the absorption affinity of shoe and stratum, thus is beneficial to carrying out smoothly of pile pulling operation.The utility model reduces the switch time of valve, improves the rate of release of internal pressure, reduces the frequency of dismounting pipeline, reduces the size of pipeline thus reduces lifting capacity, playing and increase work efficiency, be beneficial to the object that pile pulling operation is carried out smoothly.The utility model structure is simple, easy to operate, operating efficiency is high and safety and stability, has saved a large amount of time, has improve operating efficiency, drastically reduce the area the labour intensity of workman by the use of mud configuration aid, reduces labour's expenditure.Native system is the shoe spray flushing system being applicable to all jack-up units.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
As shown in the figure, 1-inlet line, 2-imported valve, 3-pressure release flexible pipe, 4-pressure relief valve, 5-flexible pipe connect union, 6-connecting hose, 7-spud leg connection union.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of shoe spray flushing system, comprise inlet line 1 and connecting hose 6, it is characterized in that: also comprise imported valve 2, pressure release flexible pipe 3, pressure relief valve 4, flexible pipe connect union 5 be connected union 7 with spud leg, the port of export of wherein said inlet line 1 connects the arrival end of imported valve 2, the port of export of described imported valve 2 connects pressure relief valve 4 respectively arrival end by tee branch is connected union 5 with flexible pipe, the arrival end of described connecting hose 6 is connected union 5 and connects with flexible pipe, the port of export of connecting hose 6 is connected union 7 and connects with spud leg; The port of export of described pressure relief valve 4 connects pressure release flexible pipe 3.
In an embodiment of the present utility model, described connecting hose 6 for length be greater than 8 meters and the flexible pipe of less than 20 meters.
In an embodiment of the present utility model, the arrival end of described inlet line 1 connects water under high pressure or gases at high pressure feedway.
In an embodiment of the present utility model, described spud leg is connected union 7 and is connected with the screwed hole on spud leg by a crossover sub.
The use procedure of this device is as follows:
Before work, first spud leg is connected union 7 and be connected with spud leg screwed hole, open imported valve 2, the water of high pressure or gas, through inlet line 1, to be connected union 5 via connecting hose 6 and to go directly bottom shoe with regard to the piping entering spud leg inside with flexible pipe.Thus, the pressure fluid provided or gas go directly the bottom of shoe, to destroy the absorption affinity of shoe and stratum, reduce the switch time of valve, improve the rate of release of internal pressure, reduce the frequency of dismounting pipeline, thus increase work efficiency, be beneficial to carrying out smoothly of pile pulling operation.When reach certain pressure top logical after, the water of high pressure or gas are cut off, then pile pulling operation, when spud leg can freedom of movement time, then relief valve 4 is opened by pressure release flexible pipe 3 pressure release, close imported valve 2, by the time when pressure release flexible pipe 3 place stops steam spraying, when the interface of connecting hose 6 and spud leg can be got at, spud leg is connected union 7 to remove from spud leg, union 5 can be connected from flexible pipe pull down if cannot get at, leave connecting hose 6 up together with spud leg, be pulled down again during pitching pile operation by the time.
