Abstract

The utility model relates to an anti-leak plaster for a flexible pipe, which is used for blocking the broken steel pipe or vessel. The utility model is characterized in that strong magnetism blocks of effective quantity are arranged into a planar array according to the manner of staggered polar. The upper surface and the lower surface of the planar array are covered with a steel wire and a rubber pad, and the utmost outer layer is a spacer sleeve. An end surface of the planar array in the spacer sleeve is provided with a push plate which passes through the spacer sleeve to be exposed. The utility model is used for blocking the steel pipe or the vessel with various curvatures, and can effectively prevent the fluid flowing over. The operation is convenient and safe, and the effect is reliable. The utility model is an ideal emergency spare part for blocking the cracked pipeline or vessel.

Description

Anti-leak plaster for flexible pipe

The utility model relates to a kind of break spare part of leak stopping of steel pipeline or container that is used for.

Industrial department and civilian communal facility extensive use steel pipeline and container transport and fluid storage medium are as water, oil, gas body and chemical industry liquid etc.These fluids often have characteristics such as high pressure, inflammable, explosive, poisonous and corrosion.Being in operation sometimes, pipeline takes place in moment and container breaks, and fluid is excessive.This class burst accident often is related to that the country and people produces and the significant problem of life, must be fast, effectively, safety, handle in time.

The fluid that prevention causes because of pipeline or container break is excessive still not to have desirable solution so far.Existing measure has: 1) throttle down repair welding leak or replacing pipeline; 2) with jet cement or glued shutoff.Because of complicated operation, first intensity is low, and success rate is not high; 3) mechanical jig leak stopping has significant limitation, and as for irregular leak, or the narrow occasion of operating position is often powerless.

Chinese patent ZL90223741.1 model utility discloses a kind of emergency leakage blocking device that is used for ship shell, it is made up of adhesive flange, rubber gasket and the lid of settling effective quantity magnetic block, lean on magnetic force that the leak stopping device is adsorbed on the leak, thereby reach the effect of leak stopping.This leak stopping device is used for the leak stopping of ship shell tabular surface and has certain effect.But, there is following shortcoming: the one, pipeline or the vessel surface bigger for curvature changing can not fully contact; The 2nd, send in the process easily and the adhesion of environment steel and iron parts generation magnetic transporting, it is inconvenient to use; The 3rd, need very careful contraposition and mechanical fasteners during operation, operation easier is big, and mending-leakage speed is slow.

In addition, above-mentioned various craft leakage mending methods all require operator in nearby operation of breach, need close the valve cutout for systems such as pressure, combustion, quick-fried, malicious, erosion are arranged, and stop conveying, otherwise influence operator's safety, thereby can not be in system's leak stopping in service.

The purpose of this utility model provides a kind of leak stopping spare part, it can leak stopping under operation of pipeline or container or user mode, and do not need the operator in nearby operation of cut, and can adapt to the pipeline or the container of various curvature, have quick, effective, safe characteristics.

The purpose of this utility model is achieved in that it is to utilize the powerful ferromagnetic adsorptivity of strong magnet to realize leak stopping, its structural feature is: the mode that the magnetic block of effective quantity interlaces by polarity is arranged into a planar array, retainer of the equal overcoat of each magnetic block.The planar array top and bottom cover steel wire, rubber pad from inside to outside successively.Scribble sealer on the rubber pad.Outermost surface is a separation sleeve.An end face in separation sleeve inner plane battle array is laid push pedal, and the bar of push pedal passes separation sleeve and exposes outside.

The also available following manner of the utility model realizes:

Magnetic block is cylindrical, is made by ndfeb magnetic material.Retainer is the abacus bead shape, is made by plastics or timber.

Rubber pad is the foam-like rubber pad that has micropore.

Separation sleeve, push pedal are made by rubber-like plastics, timber or bamboo clappers.

The utlity model has following advantage and positive effect: 1) reliable plugging effect.(BH) m of strong permanent magnet material Nb--Fe--B is about 30MGOe, is equivalent to permanent magnet and can picks up 300 times of own wt.This numerical value is applicable value, far below theoretical value.For pressure is that the fluid line of 1MPa breaks area of fracture 20cm ²The fluid total pressure is 2000N, and the adsorption force that available as calculated Nb--Fe--B permanent-magnet material 0.67Kg promptly produces is enough to block, and safety coefficient is greater than 1, the adsorption force that is equivalent to 112 of the little magnetic patch of Nb--Fe--B of diameter 10mm, high 10mm it serves to show that flexible pipe leaks the reliability of pasting.2) can adapt to the pipeline and the container of various curvature, adsorb the steel body fully effectively, closely by touching the surface.3) can be in service away from the cut operation at pipeline fluid, neither influence is produced, and compares safety again.4) transport difficult generation magnetic adhesion in the process, easy and simple to handle, quick, send the position to align flexibly, and need not mechanical fasteners.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1: the utility model structural representation

Fig. 2: Fig. 1 is along the A-A sectional drawing

Magnetic block 1 is cylindrical, and N, S the two poles of the earth are represented with black and white respectively, are made by neodymium-iron-boron magnetic material.Magnetic block 1 is enclosed within the retainer 2 that resembles abacus bead shape, and retainer 2 can be made with plastics, timber or other Nonferromugnetic material.Magnetic block 1 should have enough strings to move surplus in retainer 2, is beneficial to adsorbed close, and making again simultaneously has enough attraction distances between the adjacent magnetic block.All magnetic block is arranged by the polarity mode of interlacing, and forms a stable planar array.Respectively paste layer of steel wire net 3 in the planar array top and bottom, generation slip and self-priming, steel wire 3 outsides are pasted one deck rubber pad 4 again when preventing bending, scribble sealer on the rubber pad 4, rubber pad 4 is pressed in it on leak by the strong suction of magnetic block and tube wall during use, thereby plays the sealing and plugging effect.Separation sleeve 5 wraps up planar array, and an end leaves outlet, and the other end on opposite is laid push pedal 6, and the bar of push pedal 6 passes separation sleeve and stretches out the outside.Separation sleeve 5 adopts plank, and bamboo clappers or plastics and other nonferromagnetic material are made, to prevent the magnetic adhesion.Push pedal 6 comprises the batten that places the planar array end face and is fixed together with it and stretches out the outer stock of separation sleeve 5 that its effect is that separation sleeve is partly released in the planar array leak stopping.

Using method: flexible pipe leak pasted to send put pipeline or container cut place, the operator holds the bar of push pedal planar array leak stopping part is released from separation sleeve, after magnetic block goes out cover, powerful magnetic force firmly adsorbs with steel wall matrix immediately, the push pedal of only need pulling back immediately can be taken separation sleeve out of, and flexible pipe leaks the leak stopping part of pasting and just is adsorbed on the steel wall surface fully, blocks cut, rubber pad is compacted, the cut of then further obturaging of the sealer on the rubber pad.
