Problems solved by technology

[0002] The direction of the water column ejected by the jetting head of the jetting device in the prior art is fixed, so the action range of the jetting sediment is distributed in a point line, and the jetting area is small, and it is impossible to quickly remove the adsorption of the seabed sediment to the outer surface of the spud can. Can not achieve the best rapid spray boost effect

Embodiment

[0017] The spray flushing device working process of the present invention is as follows:

[0018] The high-pressure water enters from the interface pipe, pushes the valve core to move down, the valve core moves down in conjunction with the valve stem, and the lower end of the valve stem protrudes from the end cover, and the high-pressure water enters the horizontal vortex water inlet hole in the middle of the valve core through the interface pipe, driving the valve core to rotate, After entering the vortex inlet hole, it enters the blind hole in the center of the valve stem, and then sprays out from the vortex injection hole at the lower end of the valve stem along the blind hole. Under the reaction of the vortex injection, the valve core and stem are further driven to rotate. After the water is turned off, the valve stem moves up with the spool, and the vortex injection hole at the lower end of the valve stem retracts upwards into the middle hole of the end cover, the vortex i...

Abstract

The present invention provides a double vortex-driven swirling device for spud shoe lifting of an offshore drilling platform. The structure includes a housing, a valve core, a valve stem, an end cover and a return spring. The upper end of the valve is provided with an interface pipe, the lumen of the interface pipe communicates with the valve cavity, the lower end of the valve cavity is connected with an end cover through threads, the center of the end cover is vertically opened with a through hole, the top of the valve core is provided with a turbine, and the bottom edge of the turbine It is connected with the lower nozzle of the interface pipe to form a valve structure. The lower end of the valve core is provided with a valve stem, and the center of the valve stem is opened with a blind hole. The water hole and the vortex spray hole communicate with the vortex water inlet hole through the blind hole. The outer circle of the lower end of the valve stem passes through the vertical through hole in the center of the end cover. The outer circle of the valve stem is covered with a return spring, and the lower end of the return spring It is connected with the upper end of the end cover, and the upper end of the return spring is connected with the thrust bearing at the bottom of the spool.

Description

technical field [0001] The invention relates to the technical field of offshore oil drilling platforms, in particular to a double vortex-driven swirling device for lifting boots of offshore drilling platforms. Background technique [0002] The direction of the water column sprayed out by the jetting head of the jetting device in the prior art is fixed, so the action range of the jetting sediment is distributed in a point line, and the jetting area is small, and it is impossible to quickly remove the adsorption of the seabed sediment on the outer surface of the spud can. Can not reach the best rapid spraying and boosting effect. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a double vortex drive swirling device for spud shoe lifting of an offshore drilling platform. [0004] The technical solution of the present invention is realized in the following manner. The rotary spray device ...
