Abstract
The invention relates to a leakage repairing device of a bolt group gas pipeline. The leakage repairing device comprises a welding nut, a blowing screw and a sealing screw, wherein the welding nut is welded at a gas pipeline leakage part; a through hole is formed on the blowing screw; one end of the through hole is connected with a nitrogen input device; a blowing connector is installed at the other end of the through hole; the blowing connector is connected with the welding nut so as to perform blowing operation; and after being welded, the blowing connector is taken down and the sealing screw is installed on the welding nut. With the adoption of the leakage repairing device of the bolt group gas pipeline, the potential safety hazard during working is reduced effectively, the working intensity of working personnel during working is reduced, the effectiveness on leakage repairing is improved, and the cost on leakage repairing is reduced.
Description
Technical field
The present invention relates to a kind of gas pipe line bucket patch device, be specifically related to a kind of device that utilizes the bolt group to carry out coal gas management mending-leakage.
Background technique
The method of making the can identical with pipeline circular arc degree is adopted in gas pipe line mending-leakage at present mostly, perhaps adopts the method for relevant adhesive material cooperation auxiliary material, still; These two kinds of method mending-leakages are untimely; Can cause medium leakage in the gas pipe line, bring bigger potential safety hazard, the personnel that will cause poison and death by accident when serious; And labor intensity is big, often duplicates the phenomenon of mending-leakage.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of existing technology, provides a kind of mending-leakage timely, effectively reduces the bolt group gas pipe line bucket patch device of labor intensity and potential safety hazard.
In order to solve above technical problem, the present invention provides a kind of bolt group gas pipe line bucket patch device, comprises welded nut, purges screw rod and sealing screw rod; Said welded nut is welded on the gas pipeline leakage place; Have through hole on the said purging screw rod, said through hole one end is connected with the nitrogen input device, and the said through hole the other end is equipped with the purging joint; Said purging joint is connected with said welded nut and purges; Welding after accomplishing is taken off said purging joint, and said sealing screw rod is installed on the welded nut.
The technological scheme that the present invention further limits is: be equipped with in 4 minutes on the through hole of said purging screw rod and connect.
The invention has the beneficial effects as follows: the potential safety hazard that a kind of bolt group gas pipe line bucket patch device disclosed by the invention brings when reducing operation effectively, when alleviating operation the work personnel labor intensity and improve the validity of mending-leakage and reduce the mending-leakage cost; And; Simple in structure; Safe and reliable during operation, the processing ease applicability is strong.

Embodiment
Embodiment 1
A kind of bolt group gas pipe line bucket patch device that present embodiment provides, structure is as shown in Figure 1, comprises welded nut 2, purges screw rod 4 and sealing screw rod 6.
Welded nut 2 is welded on the gas pipeline leakage place, and the leak point of gas pipe line is welded.
Purge screw rod 4 and be used with welded nut 2, have through hole on it, said through hole one end is connected with nitrogen input device 6, and the said through hole the other end is equipped with and purges joint 3, purges joint 3 and is connected with said welded nut 2, purges behind the logical nitrogen.
Sealing screw rod 6 is used for welded nut 2 is sealed, and blocks the leakage of coal gas.Purge screw rod 4 purge accomplish after, said purging joint is taken off, said sealing screw rod be installed on the welded nut get final product.
When a kind of bolt group gas pipe line bucket patch device of the present invention is worked; After revealing appears in gas pipe line 1; Welded nut 2 is used with purging screw rod 4, welded nut 2 is welded on gas pipe line 1 leakage place, and use nitrogen to purge through the purging joint 3 that purges screw rod 4.After welded nut welding finishes, take off and purge screw rod 4, will seal screw rod 6 and be installed on the welded nut 2 and block gas leakage.
The potential safety hazard that a kind of bolt group gas pipe line bucket patch device disclosed by the invention brings when reducing operation effectively, when alleviating operation the work personnel labor intensity and improve the validity of mending-leakage and reduce the mending-leakage cost; And; Simple in structure, safe and reliable during operation, the processing ease applicability is strong.
Except that the foregoing description, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
Claims (2)
1. a bolt group gas pipe line bucket patch device is characterized in that, comprises welded nut, purges screw rod and sealing screw rod; Said welded nut is welded on the gas pipeline leakage place, has through hole on the said purging screw rod, and said through hole one end is connected with the nitrogen input device; The said through hole the other end is equipped with the purging joint, and said purging joint is connected with said welded nut and purges, after welding is accomplished; Said purging joint is taken off, said sealing screw rod is installed on the welded nut.
