Description

The plug formula that rises blocking device
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 plug formula blocking device that rises.
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 plug formula blocking device that rises comprises bolt, nut, seal and closeouts, and bolt comprises head and axial region, and the head of bolt arranges seal, is set with closeouts on the axial region of bolt, and closeouts and bolt pass through fastening nuts.
Preferably, it also comprises wrench body, and wrench body comprises spanner section and joint, and spanner section has the groove that cooperates with nut, and the joint surface has the outside thread that is connected with opener.
Preferably, be placed with magnet for the attaching nut in the groove.
Preferably, closeouts comprises the first plunger, the first partition, the second plunger and the second partition, and near an end of head to setting gradually away from head one end.
Preferably, the first plunger and the second plunger are cylindric, and are axially arranged with through hole along it, and this through hole internal diameter is consistent with the axial region diameter.
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 be carried out shutoff to the stolen valve port, can not affect in stopping transportation not to carry out quick blocking under the PRODUCTION STATUS, and plugging effect are good, safe and reliable.
Description of drawings
Fig. 1 is the main schematic representation of looking of the present invention.
Among the figure 1, spanner section, 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, axial region, 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 the accompanying drawings 1, a kind of plug formula blocking device that rises comprises bolt 9, nut 4, seal 10 and closeouts, bolt 9 comprises head 901 and axial region 902, on the head 901 of bolt 9 seal 10 is set, is set with closeouts on the axial region 902 of bolt 9, closeouts and bolt 9 are fastening by nut 4.
Consider that installation is convenient, the plug formula that rises blocking device also comprises wrench body, and wrench body comprises spanner section 1 and joint 11, and spanner section 1 has the groove 2 that cooperates with nut 4, be placed with the magnet 3 for attaching nut 4 in this groove 2, joint 11 surfaces have the outside thread that is connected with opener.
In the present embodiment, closeouts comprises the first plunger 8, the first partition 7, the second plunger 6 and the second partition 5, and near an end of head 901 to setting gradually away from head 901 1 ends.
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 axial region 902 diameter.
In the present embodiment, the first plunger 8 and the second plunger 6 are quality of rubber materials; The first partition 7 and the second partition 5 are iron.
During use, link to each other with opener by wrench body, when opener rotates, spanner section 1 matches with nut 4, thereby drive the position that bolt and upper closeouts and Sealing move to the stolen hole, finally block 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.
