The invention aims to provide a pile shoe spraying and flushing device for an ocean drilling platform, comprising a valve body, a screw plug and an end cover, wherein a high-pressure water pipe joint is arranged in the center of the upper part of the valve body, a valve cavity is arranged in the center of the lower part of the high-pressure water pipe joint, the high-pressure water pipe joint is downwards communicated with a cavity at the lower part, the lower at the outer circle of the valve body is welded on the pile shoe, the valve core is fixed in the valve body by an end cover, and the phenomenon that the valve is blocked and cannot operate due to silt deposited in the valve cavity; the valve core can rotate at least in 30 degrees through the adjustment of pump pressure, the spraying effect is more sufficient, the resources can be utilized most efficiently, and the optimal use effect is achieved.
Description
Technical field
The invention belongs to the shoe of Yu Haiyang brill well ﹑ working platform and help down device for assisting in lifting.
Background technique
Existing technology is too general, can not accurately utilize resource, can not reach most powerful spray towards effect, has only single size such as the size of valve, and the size and the quantity of the water outlet of valve are single; Existing more numerous and diverse like patent 200910256406.5 product structures, the processing difficulty, installation and maintenance convenience causes and needn't waste; Must take the valve pocket space owing to being designed with the valve port valve pocket, valve pocket is diminished, stop up spool because of the sedimentation in seawater and the back with water inlet line at valve pocket easily, valve is not worked, making troubles to platform work production causes damage.
Summary of the invention
The object of the invention is to provide a kind of efficiently marine drilling platform shoe spray of production and processing Jian Dan ﹑ installation and maintenance Jian Bian ﹑ using effect flushing device.
The technological scheme that the present invention taked is: a kind of marine drilling platform shoe spray flushing device, comprise compositions such as valve body, plug, end cap, and valve body is provided with the high-pressure water pipe interface; Valve body and high-pressure water pipe are welded together, and the bottom and the flange of valve body cylindrical weld together, and are fixed in the shoe through flange; Spool is fixed in the valve body through end cap, and the spool upper end-hole is provided with plug sealing, and level has the water inlet below the plug; The spool bottom level has hole for water spraying, and the cylindrical of below, spool water inlet is provided with a bulge loop, and the bulge loop top is provided with a back-up ring; On valve body, the back-up ring bottom becomes the wave dentation to back-up ring through screw, and the bulge loop top also becomes the wave dentation; Just coincide with back-up ring wave dentation, the angle of each tooth is 30 °, that is to say that angle of spool transposing is exactly 30 °.The inwall that bulge loop is provided with seal ring and valve body is slidingly connected, and the mud groove is scraped in the bulge loop bottom, and the bulge loop below is provided with Returnning spring between spool and end cap, and the inwall that the spool bottom is provided with seal ring and end cap is slidingly connected; Link to each other through screw thread between end cap and the valve body, end cap top has between seal ring and the valve body realizes static seal.
The invention has the beneficial effects as follows and avoided valve pocket to stop up idle phenomenon generation because of the seawater sedimentation causes valve; Spool can make spray more abundant towards scope through translation-angle (30 ° of each conversion), can most powerfully utilize resource, reaches optimized using effect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Wherein 1 is valve body, and 2 is plug, and 3 is block, and 4 is water intake, and 5 is screw, and 6 are the screw sealing, and 7 is spool, and 8 is seal ring, and 9 is seal ring, and 10 for scraping the mud groove, and 11 is spring, 12 seal rings, and 13 is end cap, 14 seal rings, 15 seal rings.
Embodiment
Be described in detail embodiments of the invention below in conjunction with accompanying drawing.
A kind of marine drilling platform shoe spray flushing device comprises compositions such as valve body 1, plug 2, end cap 13, and valve body 1 is provided with the high-pressure water pipe interface; Valve body 1 and high-pressure water pipe are welded together, and the bottom and the flange of valve body 1 cylindrical weld together, and are fixed in the shoe through flange; Spool 7 is fixed in the valve body 1 through end cap 13, and spool 7 upper end-hole are provided with plug 2 sealings, and plug 2 following levels have water inlet 3; Spool 7 bottom levels have hole for water spraying 15; The cylindrical of spool 3 water inlets belows is provided with a bulge loop, bulge loop be provided with seal ring 8 and 9 and the inwall of valve body 1 be slidingly connected, the bulge loop top is provided with back-up ring 4; Back-up ring 4 is fixed on the valve body 1 through screw 5 and screw seal ring 6; Mud groove 10 is scraped in the bulge loop bottom, and bulge loop below is provided with Returnning spring 11 between spool 7 and end cap 13, spool 7 bottoms be provided with seal ring 8 and 9 and the inwall of end cap 13 be slidingly connected; Link to each other through screw thread between end cap 13 and the valve body 1, end cap 13 tops have between seal ring 14 and the valve body 1 realizes static seal.
When high-pressure water pipe supplies water,, thereby spool 7 is moved down because the pressure of water acts on the plug 2; Cavity between spool 7 and the valve body 1 is opened, and at this moment, water flows into spool 7 inside from the water inlet at spool 7 tops; Hydraulic pressure continues to promote spool 7 and moves down, and when the hole for water spraying of spool 7 bottoms exposed end cap 13, high pressure water was just inner through the hole for water spraying ejection from spool 7; The lowering position of spool 7 is controlled by end cap 13 and the positioning step on the spool 7, thereby can not make spool 7 move down too many distance; When high-pressure water pipe stops to supply water, because the restoring force of Returnning spring 11, with spool 7 origin-location of rebounding.
To pressing down, the restoring force of Returnning spring 11 upspringed spool 7 to the pressure of water with spool 7 when high-pressure water pipe supplied water, and spool 7 will move up and down when pressure of supply water changes, and the bulge loop on the spool scrapes spool with silt scraping the mud groove, thereby avoids silt obstruction valve body.
When the pump pressure spring 11 that diminishes sets back; Wave tooth on spool 7 bulge loops will coincide with the wave tooth on the back-up ring 4; Because will the conversion several angle when active force spool of spool water outlet 15 7 coincide with back-up ring 4; Spool 7 will be forced out once more and begin water spray when increasing pump pressure, thereby reach conversion spray angle of attack degree, and spray angle of attack degree is more extensively sprayed towards better effects if.
