Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a schematic view of the cross-sectional structure of the central rubber block 4.
Detailed Description
Referring to fig. 1 and 2, the names of the components are as follows: the air bag comprises an annular air bag 1, a clamping plate 2, a bolt 3, a central rubber plug 4, a semicircular groove 5, a pipe body 6, a water hose 7, a lead-out hole 8, an inflating hose 9 and an annular air bag air inlet nozzle 10.
Referring to fig. 1 and 2, the special welding tool for blocking water leakage of a steel pipe comprises an annular air bag 1 (the cross section is circular), steel clamping plates 2 are arranged on two sides of the annular air bag 1, each clamping plate 2 is provided with a central hole (a water through hole), the clamping plates 2 are supported and positioned through bolts 3, a central rubber block 4 (for elastically clamping and sealing the clamping plates 2 and supporting the annular air bag 1) is clamped between the clamping plates 2, the center of the central rubber block 4 is provided with a central hole (a water through hole which is equivalent to the central hole of the clamping plate 2), a semicircular groove 5 (smaller than or equal to the radius of the cross section of the annular air bag) which is embedded with the annular air bag is processed on the outer circumference of the central rubber block 4 so as to be, one side of the clamping plate 2 is internally connected with a section of pipe body 6, and the other side of the clamping plate 2 is provided with a leading-out hole 8 of an annular air bag air inlet nozzle 10.
The tube body 6 is connected with a soft water band or a soft water tube 7.
The annular air bag air inlet nozzle 7 is connected with an inflating hose 9.
A splint 2: a stainless steel plate with the diameter of 180mm (outer diameter) -48 mm (inner hole) bottom cover is processed by a stainless steel plate with the diameter of 5mm, and 4 symmetrical holes with the diameter of 8mm are drilled. Pipe body 6: a stainless steel pipe is used for processing a central pipe with the diameter of 48-45 mm and the length of 150 mm. Center rubber block 4: see fig. 2, a central rubber plug of 60mm thickness is machined from rubber. The pipe body 6 is welded on the clamping plate 2, the central rubber plugging block 4 is arranged on the pipe body 6, and the annular air bag 1 is sleeved on the central rubber plugging block 4. The parts are firmly fixed by four phi 8 bolts 3. The flexible water pipe 7 with the diameter of 50 is connected to the pipe body 6 with the length of 48-45 mm with the diameter of 48-45 mm. The phi 10 inflation hose 9 is connected to the phi 8 annular bladder nozzle 10.
The implementation method comprises the following steps: the assembled sealing steel pipe without inflation, which leaks water, is placed into the steel pipe by a special welding tool, and after the position is determined, inflation is performed, so that the circular inflation ring is full of the air sealing pipeline, and the water in the pipe flows out of the central pipeline when the water amount in the pipe reaches a certain degree. The pipe wall has no water leakage phenomenon, and the two drift diameter pipelines are butted and welded. And (5) after welding. The rubber plug exhausts the gas. The steel pipe is blocked to leak water, so that a special welding tool can be conveniently pulled out of the steel pipe.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
