Description
Technical field
The present invention relates to a kind of device that carries out the shutoff repairing when pipe-line is leaked, be specifically related to a kind of cock-type blocking device.
Background technique
Along with the development of China Petroleum, long distance pipeline has become the important way of oil transportation.The area is wide, with a varied topography, soil property varies, the pipeline configuration form is varied, fed sheet of a media character is different because the long distance pipeline of burying underground passes through, thereby causes long-distance transport pipes leakage accident to occur in large quantities.
At present adopt following means for the maintenance of pipe leakage: mend plate, hoop leak stopping, block leak stopping etc., this several method can not solve the problem of repairing leak stopping.
Summary of the invention
The purpose of this invention is to provide a kind of cock-type blocking device, can not affect in stopping transportation not and carry out quick blocking under the PRODUCTION STATUS, and plugging effect is good.
To achieve these goals, the present invention is by the following technical solutions:
A kind of cock-type blocking device comprises plug, bearing, chain wheel and a plurality of claw; Plug is tubular structure, and an end is uncovered, the other end sealing, and along the circumferential direction be provided with a plurality of through holes on the plug; Bearing is arranged on the bottom in the plug; Chain wheel is positioned at the bearing top, and has inner hexagonal hole and a plurality of chute; Claw is provided with a plurality of projections that cooperate with chute, and claw can pass through hole and link to each other with chain wheel.
Further, it also comprises connecting body, and connecting body comprises the cylindrical portion that cooperates with inner hexagonal hole and with externally threaded joint.
Further, chute is two circular grooves, and arranges along the chain wheel upper surface.
Further, through hole is uniform three, and claw is three.
Further, bearing is ball bearing.
Beneficial effect of the present invention:
Can not affect in stopping transportation not and carry out quick blocking under the PRODUCTION STATUS, plugging effect is good, and is safe and reliable.
Description of drawings
Fig. 1 is the main schematic representation of looking of the present invention.
Among the figure 1, joint, 2, joint, 3, plug, 4, through hole, 5, claw, 6, projection, 7, chute, 8, chain wheel, 9, inner hexagonal hole, 10, bearing.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done further in detail, so that those skilled in the art better understand the present invention.
With reference to the accompanying drawings 1, a kind of cock-type blocking device comprises plug 3, bearing 10, chain wheel 8 and a plurality of claw 5; Plug 3 is tubular structure, and an end is uncovered, the other end sealing, and along the circumferential direction be provided with a plurality of through holes 4 on the plug 3; Bearing 10 is arranged on the bottom in the plug 3; Chain wheel 8 is positioned at bearing 10 tops, and has inner hexagonal hole 9 and a plurality of chute 7; Claw 5 is provided with a plurality of projections 6 that cooperate with chute 7, and claw 5 can pass through hole 4 and link to each other with chain wheel 8.
Consider that installation is convenient, go back the cock-type blocking device and comprise connecting body that connecting body comprises the cylindrical portion 2 that cooperates with inner hexagonal hole 9 and with externally threaded joint 1.
In the present embodiment, chute 7 is two circular grooves, and along chain wheel 8 upper surface settings.Through hole 4 is uniform three, and claw 5 is three.Bearing 10 is ball bearing.
During use, link to each other with opener by joint in the connecting body 1, when opener rotates, cylindrical portion 2 matches with the inner hexagonal hole 9 of chain wheel 8, thereby band movable chain wheel 8 rotates, and chain wheel 8 rotates claw 5 is screwed, and blocks the stolen hole on the pipeline, remove redundance after the leak stopping of stolen hole, utilize the block method to implement again shutoff.
Basic principle of the present invention and advantage have more than been described.The present invention is not restricted to the described embodiments, and in the prerequisite that does not break away from the scope of the invention, those skilled in the art can do many changes and improvements as required.Protection domain of the present invention should be defined by appending claims and equivalent thereof.
