Abstract

The utility model provides an expansion-type plugging device, which can realize quick plugging without stopping transportation and influencing production and has a good plugging effect. The expansion-type plugging device comprises a bolt, a nut, a sealing body and a plugging part. The bolt comprises a head and a shaft part. The sealing body is arranged at the head of the bolt. The plugging part is sheathed on the shaft part of the bolt. The plugging part and the bolt are tightly fixed through the nut.

Description

The plug formula that rises blocking device
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 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.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 plug formula blocking device that rises, comprise bolt, nut, seal and closeouts, and bolt comprises head and axial region, and the head of bolt arranges seal, on the axial region 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 section and joint, and spanner section has the groove coordinated with nut, and the joint surface has the outside thread be connected with opener.
Preferably, be placed with the magnet for the attaching nut in groove.
Preferably, closeouts comprises the first plunger, the first partition, the second plunger and the second partition, and from the end near 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.
The beneficial effects of the utility model:
Seal and closeouts can be carried out shutoff to the stolen valve port, can not affect under PRODUCTION STATUS and carry out quick blocking in stopping transportation not, and plugging effect is good, safe and reliable.
The accompanying drawing explanation
Fig. 1 is that the utility model master looks schematic diagram.
In 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 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 plug formula blocking device that rises, comprise 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, on the axial region 902 of bolt 9, is set with closeouts, 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 coordinated with nut 4, be placed with the magnet 3 for attaching nut 4 in this groove 2, joint 11 surfaces have the outside thread be 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 from the end near 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, by wrench body, with opener, be connected, 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 pipeline, after the leak stopping of stolen hole, remove redundance, 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.
