Abstract
The utility model relates to a plugging device which is used for the construction of the pipeline (particularly a petroleum pipeline), particularly a large caliber pipeline plugging device. The utility model is composed of an expansion block (1), expansion arms (2) and (7), a pin shaft (3), a motive power screw nut (4), ear plates (5) and (13), an expansion screw rod (6), wear-resistant rubber (8), a pin (9), a strengthening shaft sleeve (10), a retaining ring (11), a key pin (12), a sealing ring (14) and a plugging plate (15). The large caliber pipeline plugging device can be conveniently applied to the welding construction of the pipelines with all kinds of calibers (particularly the large caliber), and the large caliber pipeline plugging device which can be used for different pipe calibers with a specification has the advantages of simple structure, light weight and flexible operation.
Description
The utility model relates to a kind of blocking device that is used for pipeline (particularly petroleum pipeline) construction: the large-diameter pipe pipeline packer.
In the pipe-line construction work progress, usefulness as the interim shutoff of pipeline, existing pipeline plug mainly adopts the inner tube wall sealing, because its structural restriction makes it accommodation less (generally being used in the small-bore pipeline of φ below 159), and the pipeline plug of every kind of specification can only be applicable to a kind of caliber.In the shutoff of large diameter pipeline, generally adopt blind plate spot welding, adopt not only waste material of this method for blocking, construction trouble, and the very difficult recycling in blind plate dismounting back have increased construction cost.
Task of the present utility model is to provide a kind of large-diameter pipe pipeline packer, adopts this kind device can replace used blind plate shutoff construction process, conveniently finishes the interim shutoff in the pipeline welding frugally.
The utility model be achieved in that it by expanding block (1), expanding arm (2), (7), bearing pin (3), power nut (4), otic placode (5), (13), swelling leading screw (6), abrasive rubber (8), pin (9), set upright axle sleeve (10), back-up ring (11), key pin nail (12), seal ring (14) and shutoff plate (15) and form.Its structure and assembling feature are: shutoff plate (15) is inboard to be gluedd joint has seal ring (14), central position to be welded to set upright axle sleeve (10); Radially there is key pin nail (12) swelling leading screw (6) lower end in the circular hole, the leading screw bottom is installed in back-up ring (11) and pin (9) and sets upright in the axle sleeve (10), leading screw top is set with power nut (4), sets upright axle sleeve (10) and power nut (4) outside be welded respectively otic placode (13), (5); Otic placode (13), (5) both sides use bearing pin (3) to link to each other with expanding arm (7), (2) respectively, also adopt bearing pin (3) to link to each other between expanding arm (7), (2) both wings respectively, expanding arm (7) both wings front end also is connected with an expanding block (1) separately with bearing pin, is bonded with one deck abrasive rubber (8) on the expanding block (1).During use, this plugging device is placed in the pipeline, with special spanner rotation swelling leading screw (6), drive power nut (4), make expanding arm (2), (7) distending of its both sides, expanding block (1) is compressed tube wall, continue rotating threaded shaft, then shutoff plate (15) compresses pipe end, can reach plugging effect.Construction finishes, and unscrews the swelling leading screw, makes the expanding arm retraction, this plugging device can be taken off.
The utlity model has simple in structure, in light weight, use flexible, a kind of specification to can be used for characteristics such as different tube diameters, this device can be conveniently used in being suitable for extensive employing in the pipeline welding of various bores (particularly heavy caliber).
Accompanying drawing is a general structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, expanding block (1) is the rectangular plate, and the circular hole of a device bearing pin (3) is arranged on it; Expanding arm (2), (7) are the lath-shaped of two ends semicircular in shape, thick 4mm, and the end all has the circular hole of device bearing pin, and institute does not exist together and is, and arm (2) is a lineal shape, the circular hole that arm (7) one end band turnings, flex point place also have a dress bearing pin to use; Swelling leading screw (6) top is leading screw, and the bottom is a polished rod, leaves two radially circular holes that insert pin (9) and key pin nail (12) usefulness on it, and has a place to place the step of back-up ring (11) usefulness; Otic placode (5) and (13) are all central zone circular hole, up-small and down-big disc, and its both sides have the circular hole of device bearing pin (3) usefulness respectively; Shutoff plate (15) is the plectane of center band circular hole.
