Abstract

The utility model relates to a quick leakage stoppage node for pipelines. The utility model is composed of a rubber sealing cushion, an omega-shaped upper clamp and an omega-shaped lower clamp. The omega-shaped upper clamp and the omega-shaped lower clamp are fixedly connected with the pipeline through screw bolts. The lower end surface of the omega-shaped upper clamp is level with the horizontal central axis plane of the pipeline. The upper end surface of the omega-shaped lower clamp and the lower end surface of the omega-shaped upper clamp are provided with a gap. One surface of the rubber sealing cushion is made into a plurality of water lines with delta-shaped sealing strips, and the water lines form a plurality of squares along the wrap direction and the weft direction. The utility model solves that when the pipeline is damaged and ruptured, the leakage of the pipeline is quickly stopped under the condition of non-stop medium conveying. The utility model is widely suitable for the quick leakage stoppage of the pipelines with different materials and different pipe diameters. The utility model has the advantages of simple and convenient use and good sealing effect.

Description

Pipeline instantaneous leaking-stopping joint

The utility model relates to the repairing leak stopping of a kind of direct piping damage rupture place and pipe plugging saves fast.

At present, on carrying direct pipings such as tap water, coal gas, oil, be damaged when breaking (damage rupture among a small circle), generally there is dual mode to solve, the firstth, stop the conveying of pipeline internal medium, the damage rupture place is cut off, change pipeline again, like this, it is long in time limit not only to rush to repair pipeline, and the recondition expense height, complicated operation.The secondth, do not stop the conveying of pipeline internal medium, adopt the Hough of mechanical flexibility opposite opened to save fast, Hough joint fast is made up of last card, following card, Hough seal ring, sealing rubber strip etc., upper and lower card is through the damage rupture place of Bolt Connection wrapping at pipeline, ducted medium, because the seal action of the Hough seal ring on the Hough face in rubber weather strip and the two end part dovetail groove, hermetically sealed at pipeline damage rupture place, can reach the purpose of quick reparation at the cavity perfusion jet cement between Hough joint and the tube wall.The deficiency of its existence is, because rubber weather strip is that face contacts with pipeline, can produce poor sealing because of pipeline is uneven, easily produces and leaks; Next upper and lower card easily produces problems such as connecting not tight or distortion for splitting straight connection type in case pipeline loses the garden, influences sealing effect.

Its purpose of the utility model just is to provide a kind of pipeline instantaneous leaking-stopping joint, and the leak stopping good sealing effect is not subjected to the influence of pipeline mistake garden or distortion, and is simple, convenient.

The technological scheme that realizes above-mentioned purpose and take comprises, by rubber gasket,

On the shape card and

Shape card is down formed, and upper and lower card is fixed on the pipeline through Bolt Connection, The card lower end surface flushes with the pipe level central axis plane on the shape,

Shape down the card upper-end surface with There is a gap card lower end surface on the shape.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is this apparatus structure schematic representation;

Fig. 2 is the structural representation of this rubber gasket;

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

When pipeline damage rupture (crack length is less than half garden week) occurs when needing leak stopping, as shown in Figure 1, rubber gasket 4 is placed pipeline 5 outer wall rents, its outer installation Card 2 on the shape, on block 2 corresponding parts and install

Shape is card 1 down, and upper and lower card is connected and fixed on pipeline 5 through bolt 3, Card 2 lower end surfaces flush with the pipe level central axis plane on the shape

Shape down card 1 upper-end surface with There is a gap card 2 lower end surfaces on the shape, tight a bolt 3, utilize the gap displacement of upper and lower card connection end face, and rubber gasket 4 is close to the damage rupture place of pipeline 5 firmly, have played leak stopping, prevent the effect that pipeline internal medium is excessive.

Owing to be to utilize rubber gasket 4 to be close to pipeline damage rupture place, thereby its structure has just played important function to sealing effect, present embodiment, see shown in Fig. 2,3, rubber gasket 4 one sides are the plane, are close to card 2, and another side is some waterlines 6 that have △ shape Stamping Steel Ribbon, Stamping Steel Ribbon waterline 6 constitutes plurality of square through broadwise, and rubber gasket 4 two long limits are some △ shape serrated edges.The pressure at run-down place is dispersed in some little square sealing blocks,, does not also influence the sealing effect of whole sealing gasket, played seal action well in case there is a square sealing block to damage.When crack length is longer along conduit axis, the rubber gasket lengthening can be used, because of its two long limit is provided with serrated edge, lengthening is convenient in butt joint.In addition, when pipeline lost the garden, this rubber gasket can solve sealing problem effectively because of being provided with several little square sealing blocks.

Compared with prior art the utlity model has following advantage

1, since this to install upper and lower card connection place gapped, utilize bolt Screwing force, can implement the pressurization to rubber gasket, thereby have Good sealing effect, connect easily characteristics.

2, because the rubber gasket sealing surface of this device seals water by △ shape Line consists of some square sealings through broadwise, if whole sealing surface is separated into Do a little sealing, even a little bad seals does not affect whole sealing yet, Thereby have excellent characteristics of sealing effectiveness.

3, owing to use rubber gasket to place between card inner arc and the pipeline outer wall, only use a monoblock sealing gasket, reasonable in design, optimization, thereby structure more becomes simply, easy to use, quick.

4, be provided with serrated edge by dry rubber substance sealing gasket both sides, be convenient to lengthening and use, thereby its using scope be wide.

5, because rubber gasket is provided with the plurality of square sealing block, thus effective to the seal for pipe joints of losing the garden, can solve the problem of mistake garden seal for pipe joints effectively.
