Description
Technical field
The utility model relates to the mechanical fitting of petroleum industry ocean platform, and particularly ocean platform shoe spray is used in the bottom of ocean platform shoe towards the silt particle device, for the pitching pile and the pile pulling of shoe are sprayed towards silt particle.
Background technology
Ocean, shallow sea pitching pile formula platform, when implementing pitching pile and pile pulling, in order to make shoe and spud leg insert under water in the dirty sand smoothly or from dirty sand, to extract smoothly, just must carry out hydraulic pressure spray before pitching pile and the pile pulling towards soft processing: the general hydraulic pressure system by platform during processing to dirty sand around the shoe, bring soft dirty sand towards valve to spraying with common jet pipe of installing in the shoe or spray, carry out pitching pile or pile pulling again after soft near the dirty sand of shoe.And common jet pipe in the shoe or spray be towards valve, one, owing to be not that special-purpose spray is towards soft device, so spray is low towards efficient, cause pitching pile and pile pulling time long; Two, when the platform pitching pile degree of depth during more deeply greater than 3 meters, the platform pile pulling is unusual difficulty just; Three, traditional common jet pipe or spray be towards valve, owing to be imbedded in the dirty sand for a long time, so it is blocked nozzle to occur through regular meeting, spray blockedly towards the valve valve opening, and spraying is corroded towards valve core, spring, screw thread causes spray towards faults such as defective valves.These drawbacks have caused the time of ocean platform pitching pile and pile pulling longer, prolong the sea displacement and the construction time limit in place of whole platform greatly, thereby make platform displacement and in place can not during the maritime safety meteorology of expection, finishing, the risk when having increased the platform displacement.
Summary of the invention
The purpose of this utility model provides ocean platform shoe spray towards the silt particle device, it is had prevent the function that spray-hole and water body runner stop up and prevent to spray function towards the connector and the movable part corrosion failure of valve.Ensure normally carrying out of Offshore Platform Construction, do not incur loss through delay platform construction towards the valve fault, the risk when reducing the platform displacement because of spray.
Technical solution of the present utility model is: ocean platform shoe spray comprises valve seat, valve body and spray towards valve towards the silt particle device, and spray is installed in the valve body towards valve, and valve body is connected with valve seat.Valve seat is equipped with filter screen, lubricating structure is housed on the valve body is communicated with the spring sealed chamber of spray towards valve, prevents corrosion.Spray is provided with the current governor motion towards valve, the starting pressure of regulated fluid and enhancing impact strength.
The beneficial effects of the utility model are: when platform plug pile driving construction, water body enters spool again behind strainer filtering, reduced the blocked chance of spool runner.Spray is towards the current governor motion of valve, and the starting pressure of adjustable throttle body also makes the current at shower nozzle place strengthen impact strength.Strengthen whole device the impact strength of dirty sand has been made softization of silt particle, improved the efficient of plug stake.The multiple-sealed circle of this device has strengthened the sealing performance of whole device, has reduced the corrosion of device internal part, structure.The lubricating structure of this device is communicated with towards the spring sealed chamber of valve with spray, can annotate into lubrication oil in the annular seal space by oil filler point, makes spring in domestic work of drip ring and preservation, the application life and the functional performance that have prolonged spring.This device can ensure normally carrying out of Offshore Platform Construction, do not incur loss through delay platform construction towards the valve fault because of spray, shortened marine displacement of platform and construction period in place, platform displacement construction can be finished during the maritime safety meteorology of expection, the risk when having reduced the platform displacement.
