Abstract
The utility model discloses a jackup rig bored pile valve which comprises a valve body, wherein, the valve body is provided with a water inlet and a water outlet; the valve body is arranged on a pile shoe bottom plate; the water outlet is connected with a bored pile pipe; the water inlet is connected with a bored pile pipeline; and a valve core which controls the water inlet and the water outlet to be in open or close state is also arranged in the valve body. The utility model is provided with a controllable valve body structure between the bored pile pipeline and the bored pile pipe, controls the valve to be opened to bore, controls the valve to be closed when the boring is over, thus preventing the stoppage of the pipeline caused by that silt goes into the bored pile pipeline from the bored pile pipe during the pile inserting and boring operation process.
Description
Technical field
The utility model relates to a kind of Pilot operated check valve, particularly a kind of self-elevating drilling platform pile punching valve.
Background technique
Self-elevating drilling platform is to use at present very wide offshore drilling unit, is characterized in utilizing the landing of spud leg implementation platform that can lifting.In order to adapt to seafloor soil soft, that bearing capacity is low, increase operating water depth, bearing capacity and the stability of platform simultaneously, under each spud leg, shoe is set usually.But all there is the problem of dashing stake, pile pulling difficulty in the self-elevating drilling platform of most band shoe at present, and this is because a mode of dashing that adopts at present all is directly to apply high-pressure water flow toward dashing in the stake pipe by jetting pipeline.
Yet, all be straight-through type because these dash the stake pipe, therefore be easy to generate following problem: at first earth can enter and dash stake pipe and fixed in pipe in the pitching pile process; Secondly shoe is after going into the mud certain depth, and the soil body back-silts in drilling operation course, under the effect of seawater stream and hydraulic pressure, dashes will be full of silt in stake pipe and the jetting pipeline and form and hardens.Therefore at present when pile pulling is washed by water, at first must wash mud fixed in the jetting pipeline open with high pressure water.But because the degree varies sample that silt hardens in each jetting pipeline, when high-pressure flush, indivedual water outlet resistances are little, washed open earlier, water is pipe outflow from then on all, and hydraulic pressure descends in the pipeline, other jetting pipeline still blocks, cause having only individual pipelines to spray water, it is obviously not enough to dash the stake ability, platform can not safe pile pulling or pile pulling time of needing very long.Therefore self-elevating drilling platform should dash be provided with on the stake pipe can control, reliability is high dashes an equipment.
All be not applicable at present both at home and abroad the band shoe self-elevating drilling platform dash an equipment.
The model utility content
The technical problems to be solved in the utility model provides a kind of self-elevating drilling platform pile punching valve, can prevent that in pitching pile and drilling operation course silt from entering jetting pipeline and causing pipeline to block.
In order to address the above problem, the utility model provides a kind of self-elevating drilling platform pile punching valve to comprise: valve body, valve body are provided with water intake and water outlet, and valve body is installed on the shoe base plate, water outlet with dash the stake pipe and link to each other, water intake links to each other with jetting pipeline; In described valve body, also be provided with the spool that control water intake and water outlet are in conducting or off state.
Preferably, in described valve body, also be provided with the Returnning spring that the described spool of control is in normal off status.
Preferably, also be provided with hydraulic port on described valve body, the cross section of described spool is a T shape, and hydraulic port communicates with the step surface of described spool.
The utility model is provided with controllable valve body structure by jetting pipeline with between the stake pipe, when therefore dashing stake, control valve body is opened to dash stake, and dash stake when finishing, then control valve body is closed, thereby has prevented that in pitching pile and drilling operation course silt is deep in the jetting pipeline and causes pipeline to block by dashing a stake pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model self-elevating drilling platform pile punching valve.
In the drawings, the 1-valve body, the 2-Returnning spring, the 3-spool, the 4-seal ring, 5-hydraulic pressure mouthpart, the 6-intermediate plate, 7-shoe base plate, 8-dash the stake pipe, and 9-safety cover, 10-dash the stake water intake.
Embodiment
Below in conjunction with Figure of description the utility model is further described.
As shown in Figure 1, the utility model comprises: valve body 1, valve body 1 are provided with water intake 10 and water outlet 11, and valve body 1 is installed in shoe base plate 7 by intermediate plate 6.Water outlet 11 with dash stake pipe 8 and link to each other, water intake 10 links to each other with jetting pipeline 12.Intermediate plate 6 can be fixed on the shoe base plate 7 by welding manner, and its upper surface is a working surface, can be tightly connected by seal ring and thread connecting mode and valve body 1.In valve body 1, also be provided with the spool 3 that control water intake 10 and water outlet 11 are in conducting or off state.
In order to make spool 3 can be in normally off, even water intake 10 and water outlet 11 are in the state that normal off is opened, in valve body 1, also be provided with Returnning spring 2, Returnning spring 2 can adopt metal spring as shown in Figure 1, also can adopt other structure, make spool 3 be in normally off as long as can play.When operating water depth was big, Returnning spring 2 can use compressed-gas springs; If the use metal spring can be provided with the aperture of being with filter on valve body 1 top, the interior water body of valve body 1 epicoele and shoe is communicated with.By in conjunction with hydraulic pressure,, also can play the effect that spool 3 can be resetted even reduce the design size of the spring thread of metal spring.
As shown in Figure 1, can make water intake 10 and water outlet 11 be in the state of conducting in order to control spool 3, promptly dash the stake working state, also be provided with hydraulic port 5 on valve body 1, the cross section of spool 3 is a T shape, and hydraulic port 5 communicates with the step surface 31 of spool 3.Like this, when when hydraulic port 5 pumps into high-pressure medium, high pressure oil heads on step surface 31 spool 3 is moved up, thereby opens valve body 1, makes water intake 10 and water outlet 11 be in the state of conducting.When with the medium pressure release in the hydraulic port 5, spool 3 just falls under the effect of Returnning spring 2, makes water intake 10 and water outlet 11 be in closed condition.The inner chamber of valve body 1 should be the step cylinder mutually, between the inner chamber of valve body 1 and the spool 3 seal ring 4 can also be set.
At platform pitching pile and drillng operation state, dash stake water intake 10 and hydraulic port 5 no impressed pressures, spool 3 forms sealing with valve body 1 under Returnning spring 2 effects, prevent that seafloor soil from entering valve body 1 and jetting pipeline 12; When before pile pulling, needing to dash stake, pumping into high-pressure medium from hydraulic port 5 on platform moves spool 3, on platform, pump into towards a stake seawater from dashing stake water intake 10, wash each open and manage 8 interior silts towards stake, then according to dashing the bath of stake program required pressure and discharge capacity, destroy the adhesive force of shoe and seafloor soil, be convenient to pile pulling.When dashing the stake end of job, control is rushed down pressure from hydraulic port 5 on platform, and spool 3 is moved down, and dashes the stake valve and is in closed condition again.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
