Abstract

A pipeline mending leakage device is provided with an arc-shaped upper shell body (1) and lower shell body (7), the upper shell body and the lower shell body are respectively welded with a guide baffle (2) and a guide baffle (8), one end of the upper shell body and the lower shell body is hinged with an axis pin (9), the other end is provided with a pull rod (3) with via-hole and a screw drawbar (5) with inner thread inside the circular tank formed by the upper shell body and the lower shell body. An inner hexagon screw (4) is screwed in the screw drawbar through the drawbar. The inner surface of the upper shell body and the lower shell body is provided with a sealed tube with incision. The utility model has a reasonable structure design, is widely applied, has good effects of mending leakage and sealing, is convenient, flexible, secure and reliable, and does not affect the normal work, with much practical value.

Description

The blocking Leakage device

The utility model relates to a kind of mending-leakage seal arrangement of fluid line.

Existing various pipes is in operation if leak, after general employing rubber plate or plastic film are wrapped, fixed with steel wire or sheet metal again or adopt clip that pipeline is clamped, between clip and pipeline, form cavity and in cavity, inject sealer then, or directly method such as weld, but these mending-leakage modes all exist sealing effect bad in leak, perhaps need to stop, cause delay work, time-consuming, and it is also very loaded down with trivial details to operate, the also more high shortcoming of cost.In recent years, relevant technologies personnel have developed the device that directly carries out blocking Leakage at work, as practical New Name be: a kind of pipe leakage clip of meeting an urgent need, the patent No. is: 98227222 and the model utility name be called: pipe leakage first aid folder, the patent No. is: 87,206,302 two patents, it all adopts the structure of establishing seal ring in the upper and lower casing, mounting board in leak in order to leak-stopping, but its shortcoming is, poor sealing performance, use inconvenience, the life-span is low etc., does not solve the problem of mending-leakage and sealing fully.

The purpose of this utility model is: a kind of good seal performance is provided, and easy to use, the novel pipeline bucket patch device that the life-span is long.

The purpose of this utility model is achieved in that the blocking Leakage device comprises the upper and lower casing of circular arc, the cross section of this upper and lower casing is " U " shape, axially there is aduncate edge at two ends, the height on edge is about half of its inner seal ring thickness, upper and lower casing one end is hinged with bearing pin, the other end respectively has a cylinder, the pull bar and the screw pull bar that can rotate in cylinder are housed respectively, and to through hole should be arranged, wherein the through hole on the screw pull bar can process internal thread on pull bar and the screw pull bar; On upper and lower casing, fix a deflector apron respectively, deflector apron be upper and lower casing along the outward extending arc of its camber line, its cross section also is " U " type, the internal surface of seal ring is made of rough circular arc camber, and vertically a kerf is arranged.

Owing to adopted technique scheme, at first since pull bar and screw pull bar can rotate, angle adjustable, align through hole, time saving and energy saving when spinning with screw, second, each fixes a deflector apron on the upper and lower casing, can make each position of seal ring stressed evenly, and can realize that a blocking Leakage device is used for the pipeline of different tube diameters, the 3rd, all there is aduncate edge on the upper and lower casing both sides, be used for preventing that seal ring from outwards moving, last because seal ring employing internal surface is that rough circular arc camber constitutes, can guarantee extraordinary sealability.

Below by embodiment and be described with reference to the accompanying drawings as follows:

Figure of description is the utility model structural representation

Referring to accompanying drawing: the utility model blocking Leakage device comprise circular arc on, lower shell body (1), (7), its cross section is " U " type, axially there is reclinate edge at two ends, the height on edge is approximately half of seal ring (6) thickness, on, lower shell body one end is hinged with bearing pin (9), the other end respectively has a cylinder, the pull bar (3) and the screw pull bar (5) that can rotate in cylinder are housed respectively, through hole on the screw pull bar (5) can be processed as internal thread, fastening piece (4) is a socket head screw, last, fix a deflector apron (2) in the lower shell body respectively, (8), deflector apron is last, lower shell body (1), (7) along the outward extending arc of its camber line, its cross section also is " U " type, on, in the lower shell body is sealing drum (6), the sealing drum internal surface is made of rough circular arc camber, and vertically a kerf is arranged.

When pipeline takes place to leak, at first select corresponding blocking Leakage device according to the size of outer diameter tube, open upper and lower casing (1) then, (7) open it, sealing drum (6) is pressed in the pipe leakage place upper and lower casing is closed to be screwed in the screw pull bar (5) by pull bar (3) with fastening piece (4) screws, just finished the mending-leakage work of pipeline this moment.
