Abstract

The utility model provides a device used for the leak plugging of pipelines, particularly a leak plug pitch hoop. The leak plug pitch hoop is provided with a pair of pitch hoops which are connected by a joint or a hinge, and the diameters of the pitch hoops are identical with the diameter of a duct needed to be repaired or slightly bigger than the diameter of the duct needed to be repaired; each inner surface of the pitch hoop is provided with a sealing ring, and each outer surface of the pitch hoop is provided with a pair of clamping ears and a fastening bolt. The utility model has the advantages of high speed, simple operation, wide application range, and convenient and practical working process; an ordinary technician can operate the leak plug pitch hoop; manpower, material resources and financial resources can be saved largely.

Description

Leak plug pitch hoop

The device that the utility model provides a kind of pipeline mending-leakage to use belongs in the pipeline supplementary equipment technical field.

At present, various pipelines are because aging, the leakage of small size takes place in corrosion, the mending-leakage mode that great majority adopt is: with the steel pipe of the same diameter dimension of a joint, sever with gas cutting, wrap various oil resistant packings, punch then and fix with screw, sometimes the transportation work that needs to stop leakage line being repaired, thereby reduce its work output, in fire warden, need employ fire protection equipment, working strength is big and inconvenient, and needs technical professional operation, from look for steel pipe small opening-gas cutting sever-punch-screw is fastening-several procedures such as draining rust cleaning, under the situation that local condition is for example prevented fires and condition such as machine maintenance does not possess, can not in time finish its mending-leakage work.

The purpose of this utility model is to overcome above-mentioned defective and provide a kind of easy for operation, Leak plug pitch hoop simple in structure.

The purpose of this utility model realizes in the following way: connect into a pair of clip with diameter identical or slightly bigger with the pipe diameter of required repairing with hinge or hinge, the internal surface of this clip has sticked with glue or has posted a seal ring, by a pair of card ear is arranged, Leak plug pitch hoop is clamped on the purpose that reaches mending-leakage on the steel pipe by fastening screw then on the outer surface of this clip.

The utility model is compared with existing blocking Leakage equipment has following advantage: mending-leakage speed is fast, does not delay the duration; Can be adapted to the repairing of various breaches; Simple to operate, safety can save fire personnel and vehicle, required power supply and the rust cleaning draining supervisor of electric welding machine in fire warden; Adapt to widely, those of ordinary skill just can be operated, and its working procedure is convenient and practical, can save human and material resources, financial resources in large quantities.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is embodiment's schematic perspective view of the present utility model;

Fig. 2 is another embodiment's schematic perspective view of the present utility model;

Fig. 3 is the side view of Fig. 2;

Fig. 4 is Fig. 1,2 A-A sectional structure chart;

Fig. 5 is another example structure figure of the present utility model;

Referring to Fig. 1, Fig. 4, Leak plug pitch hoop of the present utility model by the internal surface that connects into a pair of clip 1 with the identical or slightly bigger diameter of pipe diameter with required repairing, this clip 1 with hinge or hinge 4 stick with glue by or post and be equipped with a pair of card ear 2 on the outer surface of a seal ring 3, this clip 1 and clamping bolt is formed, on clip 1 and the seal ring 3 opening is arranged, clamping bolt comprises a nut 6 and a double-screw bolt 5.

From Fig. 4, Fig. 5 as seen, Leak plug pitch hoop of the present utility model is stained with the seal ring 3 of an opening on the internal surface of clip, the internal diameter of a pair of clip 1 that is connected by hinge or hinge 4 is decided by the line size of required repairing, the clip 1 that hinge or hinge 4 connect can be opened to 180 degree, can successfully repair, accomplish easy to operate simple.Clip among Fig. 4 is two accessories with the card ear, welds together regularly.Clip among Fig. 5 is structure as a whole with the card ear.On the card ear fastening screw keyhole is arranged.

Fig. 1 and Fig. 2 are the Leak plug pitch hoop of different length, and its length dimension as required can also extend arbitrarily.

Leak plug pitch hoop of the present utility model can be made into a series of products according to the size of the pipe diameter of the required repairing leak of reality, is 3,4,6,8 inches etc. as the inner diameter of clip.The length of whole Leak plug pitch hoop can be selected different sizes such as 25cm, 50cm for use, and its seal ring can be selected the corrosion resisting elastic rubber ring that has opening for use.

The utility model can be applied to the repairing of various oil line pipes, also can be used to repair leak in various pipelines.
