The expansion plugging device comprises a bolt, a nut, a sealing body and a plugging element, wherein the bolt comprises a head part and a shaft part, the sealing body is arranged at the head part of the bolt, the plugging element is sleeved on the shaft part of the bolt, and the plugging element and the bolt are fastened by the nut.
Description
Technical field
The present invention relates to a kind of for leaking pipe-line time carry out the device of shutoff repairing, be specifically related to one and rise plug blocking device.
Background technique
Along with the development of China Petroleum, long distance pipeline has become the important way of petroleum transportation.Because the long distance pipeline buried underground passes through, area is wide, with a varied topography, soil property varies, pipeline configuration form is varied, fed sheet of a media is distinct, thus causes long-distance transport pipes to occur leakage accident in large quantities.
Maintenance at present for pipe leakage adopts following means: 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 object of this invention is to provide a kind of cock-type blocking device, quick blocking can be carried out under on-line production does not affect PRODUCTION STATUS, and plugging effect is good.
To achieve these goals, the present invention is by the following technical solutions:
One rises plug blocking device, and comprise bolt, nut, seal and closeouts, bolt comprises head and axle portion, and the head of bolt arranges seal, and the axle portion of bolt is set with closeouts, and closeouts and bolt pass through fastening nuts.
Preferably, it also comprises wrench body, and wrench body comprises spanner portion and joint, and spanner portion has the groove with nut screw connection, and joint surface has the outside thread be connected with opener.
Preferably, the magnet for attaching nut is placed with in groove.
Preferably, closeouts comprises the first plunger, the first partition, the second plunger and the second partition, and sets gradually from the one end near head to away from head one end.
Preferably, the first plunger and the second plunger are cylindric, and are axially arranged with through hole along it, this through hole internal diameter and shaft portion diameter in the same size.
Preferably, the first plunger and the second plunger are quality of rubber materials.
Preferably, the first partition and the second partition are iron.
Beneficial effect of the present invention:
Seal and closeouts can carry out shutoff to stolen valve port, can carry out quick blocking, and plugging effect are good, safe and reliable under on-line production does not affect PRODUCTION STATUS.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present invention.
In figure 1, spanner portion, 2, groove, 3, magnet, 4, nut, the 5, second partition, the 6, second plunger, the 7, first partition, the 8, first plunger, 9, bolt, 901, head, 902, axle portion, 10, seal, 11, joint.
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 accompanying drawing 1, one rises plug blocking device, comprises bolt 9, nut 4, seal 10 and closeouts, bolt 9 comprises head 901 and axle portion 902, the head 901 of bolt 9 arranges seal 10, the axle portion 902 of bolt 9 is set with closeouts, it is fastening that closeouts and bolt 9 pass through nut 4.
Consider that installation is convenient, the plug that rises blocking device also comprises wrench body, and wrench body comprises spanner portion 1 and joint 11, and spanner portion 1 has the groove 2 coordinated with nut 4, be placed with the magnet 3 for attaching nut 4 in this groove 2, joint 11 surface has the outside thread be connected with opener.
In the present embodiment, closeouts comprises the first plunger 8, first partition 7, second plunger 6 and the second partition 5, and sets gradually from the one end near head 901 to away from head 901 one end.
In the present embodiment, the first plunger 8 and the second plunger 6 are cylindric, and are axially arranged with through hole along it, and this through hole internal diameter is consistent with axle portion 902 diameter.
In the present embodiment, the first plunger 8 and the second plunger 6 are quality of rubber materials; First partition 7 and the second partition 5 are iron.
During use, be connected with opener by wrench body, when opener rotates, spanner portion 1 matches with nut 4, thus drive bolt and upper closeouts and Sealing to move to the position in stolen hole, finally block the stolen hole on pipeline, after the leak stopping of stolen hole, remove redundance, utilize block method to implement shutoff again.
The foregoing describe basic principle of the present invention and advantage.The present invention is not restricted to the described embodiments, and is not departing from the prerequisite of the scope of the invention, and those skilled in the art can do many changes and improvements as required.Scope should be defined by appending claims and equivalent thereof.
