The cock type blocking device comprises a plug, a bearing, a chain wheel and a plurality of jaws; the plug has a cylindrical structure; one end of the plug is open, and the other end of the plug is enclosed; a plurality of through holes are formed in the plug along a circumferential direction; the bearing is arranged at the bottom in the plug; the chain heel is positioned above the bearing, and is provided with an inner hexagonal hole and a plurality of sliding chutes; the jaws are provided with a plurality of bumps matched with the sliding chutes; the jaws can be connected with the chain wheel by passing through the through holes.
Description
Technical field
The utility model relates to a kind of device that carries out the shutoff repairing when pipe-line is leaked, and is 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.Because the long distance pipeline of burying underground passes through, area is wide, with a varied topography, soil property varies, the pipeline configuration form is varied, fed sheet of a media character is different, thereby causes long-distance transport pipes leakage accident to occur in large quantities.
Maintenance for pipe leakage at present adopts following means: mend plate, hoop leak stopping, block leak stopping etc., this several method can not solve the problem of repairing leak stopping.
The model utility content
The purpose of this utility model is to provide a kind of cock-type blocking device, can not affect under PRODUCTION STATUS and carry out quick blocking in stopping transportation not, and plugging effect is good.
To achieve these goals, the utility model is by the following technical solutions:
A kind of cock-type blocking device, comprise 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 plug; Bearing is arranged on the bottom in 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 coordinate with chute, and claw can be connected with chain wheel through through hole.
Further, it also comprises connecting body, and connecting body comprises the cylindrical portion that coordinates 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.
The beneficial effects of the utility model:
Can not affect under PRODUCTION STATUS and carry out quick blocking in stopping transportation not, plugging effect be good, safe and reliable.
The accompanying drawing explanation
Fig. 1 is that the utility model master looks schematic diagram.
In 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 utility model is done further in detail, so that those skilled in the art better understand the utility model.
With reference to accompanying drawing 1, a kind of cock-type blocking device, comprise 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 plug 3; Bearing 10 is arranged on the bottom in 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 coordinate with chute 7, and claw 5 can be connected with chain wheel 8 through through hole 4.
Consider that installation is convenient, go back the cock-type blocking device and comprise connecting body, connecting body comprises the cylindrical portion 2 that coordinates 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, by joint in connecting body 1, with opener, be connected, when opener rotates, cylindrical portion 2 matches with the inner hexagonal hole 9 of chain wheel 8, thereby band movable chain wheel 8 rotates, chain wheel 8 rotates claw 5 is screwed, and blocks the stolen hole on pipeline, remove redundance after the leak stopping of stolen hole, utilize the block method to implement again shutoff.
Basic principle of the present utility model and advantage have more than been described.The utility model is not restricted to the described embodiments, and in the prerequisite that does not break away from the utility model scope, those skilled in the art can do many changes and improvements as required.The utility model protection domain should be defined by appending claims and equivalent thereof.
