Abstract

The utility model discloses a device for covering leakage from an outside pipeline. With the purposes that no influence to a pipeline, media can be continuous to be conveyed, and pipeline leakage points can be repaired rapidly and safely, a device for covering leakage from the outside pipeline is adopted. The utility model comprises a tile for covering leakage and a clamping device which leads the tile for covering leakage to be pressed on the pipeline leak points. A lifting lug is arranged on the upper surface of the tile for covering leakage, and a sealing cushion is arranged on the lower surface of the tile for covering leakage. The utility model can not influence normal production and can strictly separate the media in the pipeline from the outside. Then, safe repair can be achieved. The utility model is suitable for the occasions where pipelines with conveying gas, liquid, inflammable media, explosive media, strong corrosion media, and toxic media leaks and needs repairing.

Description

A kind of pipe plugging watt device

The utility model discloses a kind of pipe plugging watt device.

When various flowing mediums such as line transportation water, gas, oil, acid, alkali, salt, compound, polymer, because material defectives such as the sand holes that pipeline exists in manufacture process, pore, slag inclusion, perhaps the intensification of the pit of pipeline internal pitting in use is so that penetrate or artificial damage all will cause the leakage of fed sheet of a media, and this is the thing that often occurs in pipe network.

When leakage situation takes place when, even for aperture that has only 1mm or the crackle that only is in the seepage state, also must close the valve that leaks the pipeline section two ends, emit medium wherein, to change then or repair, this will bring loss to production certainly.If the medium of not emitting wherein promptly directly welds mending-leakage, when the medium of carrying is inflammable, explosive gas, liquid or strong acid, highly basic, poisonous medium, must cause serious accidents such as burning, blast to take place, or make the maintenance man be subjected to the grievous injury of medium.

The purpose of this utility model is to provide a kind of pipeline that can neither influence when leaking appears in pipeline to continue the pipe plugging watt device that fed sheet of a media can be realized quick and safe reparation leakage pipe again.

The purpose of this utility model is achieved in that a pipe plugging watt device comprises leak stopping watts 6 and leak stopping watts 6 is pressed on the locational holding device of pipe leakage, there is hanger 9 at the centre of form place of leak stopping watt 6 upper surfaces, leak stopping watt 6 lower surfaces are stained with sealing gasket 10, sealing gasket 10 is rubber pad, plastic mattress, rubber plastic pad or graphite pads, the edge of sealing gasket 10 is apart from the outer rim 3-10mm of leak stopping watts 6, and the thickness of sealing gasket 10 is 1-5mm.

Holding device comprises dismountable stay bolt 1, crossbeam 2, clamping screw rod 4 and base 8, end near clamping screw rod 4 has along circumferential annular groove, it inserts in the hanger 9, from the pair of holes of hanger 9, insert the annular groove that passes clamping screw rod 4 with U type latch 5, again passing the pair of holes in addition from hanger 9.Base 8 is V-shaped or be the circular arc type that matches with the pipeline external form with the contact position of leakage pipe 7.

The utility model has the advantages that when pipeline because of holes, when leaking appears in the crack, do not stopping the line transportation medium, do not emitting under the situation of its medium, available holding device watt tightly is pressed in leak stopping on the leakage position of pipeline, by sealing gasket leakage point is blocked, medium in the pipeline and extraneous strictness are kept apart, again the periphery and the pipeline welding of leak stopping watt are got up, even what carry in the pipeline is the situation that combustion explosion also can not take place inflammable, explosive medium, this obviously is a kind of easy, quick, safe Pipe leakage stopper that does not influence production again.

Fig. 1 is a pipe plugging watt installation drawing.

Fig. 2 is the structural drawing of leak stopping watt.

The utility model is described in further detail below in conjunction with embodiment.

The through-wall crack of long 18mm appears in Ф 100mm gas pipe line, causes gas leakage.On plate bending rolls, steel plate is rolled into Ф 115mm, cut off 100 * 60mm and do leak stopping watts 6, with the steel pipe of Ф 32 * 30 * 3mm apart from lower end 10mm be in respectively bore Ф 6mm in 12mm place, diameter both sides through hole as shown in Figure 2, again it is welded in leak stopping watt 6 a upper surface centre of form places and makes hanger 9, the flexible graphite paper of 90 * 50 * 2mm is bonded on the lower surface of leak stopping watts 6 and makes sealing gasket 10.Place pipeline 7 to leak the opposite of side base 8, the fourth head of two stay bolts 1 is put into the T type groove of base 8, and the nut 3 of screwing on is put packing ring, clamping screw rod 4 is screwed on the crossbeam 2, install to leak stopping watts 6 on the clamping screw rod 4 and insert U type latch 5, again with crossbeam 2 through on the studdle 1, put packing ring and screw nut 3, rotation clamping screw rod 4 is pressed on the centre of form of leak stopping watts 6 and leaks the center, leak stopping watt 6 peripheries are welded on the pipeline 7, extract U type latch 5 out, unload holding device.
