The further technological scheme of the utility model is: the degree of depth of described step is 2 ~ 3mm.
Further, the diameter of the hollow structure of described pad is equal with the aperture of nut.
Further, the distance of nut given prominence to by described pad is 1 ~ 3mm.
Further, described pad is that rubber material or silica gel material processing and fabricating form.
Further, the specification of described nut is M16 ~ M42.
Further, the leakage hole place of described pipeline is also provided with a dismountable honeycomb duct, and the external diameter of honeycomb duct is not more than the aperture of nut.
Further, the quantity of described step is two, and two steps are symmetrical along nut center line, and arcuate structure is that front and back are symmetrical along nut center line, has part step to be in arcuate structure.
The utility model compared with prior art has following features:
(1) the low pressure steel pipe bucket patch device that the utility model provides adopts the mating reaction of pad, nuts and bolt, the Rapid leakage repairing realizing pipe leakage mouth place while not closing duct can be realized, and sealing is higher, structure is simple, easy to operate, and pad effectively can stop liquid runs down tube wall stream, ensure that welding quality is higher;
(2) the low pressure steel pipe bucket patch device that the utility model provides can realize the Rapid leakage repairing of the leak source directly over vertical tube and horizontal pipe, during leakage point directly over repairing, only need by honeycomb duct by liquid guide flow to nut side, simple and convenient;
(3) the low pressure steel pipe bucket patch device that the utility model provides utilizes the nut of common, easy purchase, bolt is transformed slightly, does not need additional processing screw thread, saves time, laborsaving;
(4) the large I of low pressure steel pipe bucket patch device nut that provides of the utility model is from M16 to M42, and scope is comparatively large, can realize the mending-leakage of different leakage hole.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of nut in the utility model.
Embodiment
As shown in drawings: a kind of low pressure steel pipe bucket patch device, comprise pipeline 1, nut 3, bolt 5, leakage hole in the screw align with tube 1 of nut 3 is together with pipeline welding, bolt 5 to extend in nut 3 and welds together, one end of nut 3 is provided with a step 3-1, is provided with soft pad 2 in step 3-1, and pad 2 is hollow structure, object allows liquid pass through in the middle of pad 2, ensures that nut 3 and pipeline 1 wall weld are anhydrous; Bolt 5 is wound with the flax silk 4 soaked, improves the sealing between bolt 5 and nut 3; Part nut 3 having step 3-1 one end end face is arcuate structure 3-2, and the radian of arcuate structure 3-2 and pipeline 1 outer wall matches, and the stickiness be convenient between nut 3 and pipeline 1 is better, has both been beneficial to raising sealability, and has conveniently welded again.
The degree of depth of step 3-1 is 2mm; The quantity of step 3-1 is two, and two step 3-1 are symmetrical along nut 3 center line, and arcuate structure 3-2 is that front and back are symmetrical along nut 3 center line, has part step 3-1 to be in arcuate structure 3-2.
The diameter of the hollow structure of pad 2 is equal with the aperture of nut 3, and conveniently water flows out from hole; The distance that nut 3 given prominence to by pad 2 is 2mm, pad 2 is first contacted with pipeline 1, and then nut 3 and pipeline 1 is welded together, pad 2 is welded on inside, reduces liquid and flows out along pipeline 1 outer wall, affect welding quality; Pad 2 forms for rubber material processing and fabricating, has certain elasticity, can ensure that the sealing between pad 2 and pipeline 1 is better, but also be not easy to skid.
The specification of nut 3 can be M16 ~ M42, specifically carries out the size of choose reasonable nut 3 according to the size of leakage hole.
The leakage hole place of pipeline 1 is also provided with a dismountable honeycomb duct (for illustrating in figure), the external diameter of honeycomb duct is not more than the aperture of nut 3, when repairing the leakage point directly over horizontal pipe, first by honeycomb duct insert nut 3 aperture in by the side of a part of liquid drain to nut 3, the impact of fluid pressure welding quality can be reduced.
Working principle of the present utility model and using method are: first determine nut 3 used according to the size of leakage hole size, one end of nut 3 is processed two step 3-1, pad 2 is put in the step 3-1 in nut 3, then according to the shape of pipeline 1, the corresponding position, one end of step 3-1 is had by nut 3 to be processed into the arcuate structure 3-2 with pipeline 1 mating shapes, pad 2 is close to pipeline 1 outer wall, and the screw of nut 3 is aimed at leakage hole compression, ensure that the matching of arcuate structure 3-2 and pipeline 1 is better simultaneously, then adopt the mode of built-up welding that nut 3 and pipeline 1 are welded together, then be screwed in nut 3 after the bolt 5 supporting with nut 3 being twined the flax silk 4 soaked, finally nut 3 and bolt 5 are welded together, for the situation that hydraulic pressure strengthens, make as leakage hole is positioned at directly over pipeline 1, before nut 3 compresses pipeline 1, first welding nut 3 with pipeline 1 is carried out again in one end that a part of liquid rotating to be moved on to nut 3 through nut 3 aperture by honeycomb duct, after having welded, honeycomb duct is extracted out, the bolt 5 being tied with and soaking flax silk 4 is screwed into again in nut 3.
