At present, when water leak accident occurring under coal mine, connecting tube carries out draining to the permeable security incident that occurs and speedily carries out rescue work rapidly, and the personnel in the pit is implemented rescue.Existing flange connects the draining pipeline of speedily carrying out rescue work, because connecting through hole is too many on the flange plate, the bolt connection in the installation process can spend the plenty of time, and it is slow to make pipeline that the speed that connects is installed, and is unfavorable for carrying out smoothly fast of draining rescue pipe fitting.
The model utility content
Technical problem to be solved in the utility model is: a kind of plastic lining composite steel pipe of using in the draining rescue operation be convenient to is provided.
For solving the problems of the technologies described above the technological scheme that adopts be: a kind of plastic lining composite steel pipe, comprise lining plastic compound steel tube body and the connecting head that is welded on described plastic lining composite steel pipe body end, also comprise rubber seal and the fast joint structure that the described connecting head of adjacent two plastic lining composite steel pipe body end is linked together fast, described rubber seal is between two connecting heads that link together by described fast joint structure.
Further be, described fast joint structure is two semicircular ring that cross section is trench structure, and described connecting head is connected in the described trench structure.
Further be, be provided with the connecting bolt hole in the end of the ring-like fast joint structure of each described semicircle, two ring-like fast joint structures of described semicircle connect as a whole by the connecting bolt that is installed in the described connecting bolt hole.
Further be, the radially-outer surface that described connecting head is positioned at lining plastic compound steel tube body one side is provided with quick connection inclined-plane, and described fast joint structure links together fast by the described connecting head of described quick connection inclined-plane with adjacent two plastic lining composite steel pipe body end.
Further be, be provided with rubber seal in the side relative with described quick connection inclined-plane of described connecting head and hold half chamber, after the described connecting head of adjacent two plastic lining composite steel pipe body end linked together by described fast joint structure, described rubber seal was crimped on adjacent two described glue seal rings and holds in the receiving cavity of half chamber formation.
Further be, the cross section of described rubber seal is V-type, and its axial thickness is greater than the axial thickness of described receiving cavity.
Further be between described rubber seal and described connecting head, also to be furnished with the polyvinyl plastics anticorrosive coat.
The beneficial effects of the utility model are: by a described fast joint structure is set, and when needs link together adjacent two described lining plastic compound steel tube bodies, earlier described rubber seal is placed between the connecting head of described two lining plastic compound steel tube bodies, and then adopts described fast joint structure that described connecting head is coupled together fast.Like this, described lining plastic composited pipe is convenient to use in the draining rescue operation that needs connect fast, in order to save the connect hours, improves rescue efficient; Also be fit to simultaneously be convenient to use in the quick fluid-transporting tubing that connects of other field needs.
