Abstract
A kind of rapid abutting joint pipe of the utility model, there is body, the two ends mouth of pipe of body is all connected with flange, the mouth of pipe end face of flange plate end face all with corresponding of described two flanges is concordant, the flange plate end face of described body one side flange is provided with circular groove, one sealing gasket is provided with annular protrusion, the circular groove of flange plate and the annular protrusion of sealing gasket in mating connection, the neck flange tail end of described two flanges all welds with tube body wall; The utility model structure is simple, convenient and flexible operation, by paperback and single solder design of ductile iron pipe and flange, avoid the risk that the interaction of existing two pass weld residual stress produces weld metal crack, solve the seepy question that in weld seam, penetrability slag blister, microscopic crack cause, have manufacturing efficiency high, cost of production rises low, sealability is reliable, docks the features such as quick and convenient between tube and tube.
Description
Technical field
The utility model relates to ductile iron pipe manufacture field, in particular for a kind of rapid abutting joint pipe of tubing docking in cast tube industry.
Background technique
At present, in cast tube enterprise, traditional ductile iron pipe is all adopt flange plate to stretch out mouth of pipe assembling, again the sealing of two pass circumferential weld is carried out to flange head end and tail end after assembling, due to the interaction of two weld residual stress, very easily crack, cause pipe joint to leak, cause serious quality problems.
Summary of the invention
The purpose of this utility model is improved above shortcoming exactly, and provide a kind of flange plate of ductile iron pipe and the single solder design of nose end paperback, flange not easy-rupturing leaks, a kind of rapid abutting joint pipe of good airproof performance.
Concrete scheme of the present utility model is: a kind of rapid abutting joint pipe, there is body, the two ends mouth of pipe of body is all connected with flange, it is characterized in that: the mouth of pipe end face of flange plate end face all with corresponding of described two flanges is concordant, the flange plate end face of described body one side flange is provided with circular groove, one sealing gasket is provided with annular protrusion, the circular groove of flange plate and the annular protrusion of sealing gasket in mating connection, the neck flange tail end of described two flanges all welds with tube body wall.
The utility model structure is simple, convenient and flexible operation, by paperback and single solder design of ductile iron pipe and flange, avoid the risk that the interaction of existing two pass weld residual stress produces weld metal crack, solve the seepy question that in weld seam, penetrability slag blister, microscopic crack cause, have manufacturing efficiency high, cost of production rises low, sealability is reliable, docks the features such as quick and convenient between tube and tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is gasket structure schematic diagram of the present utility model.
In figure, 1-body, the 2-mouth of pipe, 3-flange, 4-flange plate end face, 5-sealing gasket, 6-circular groove, 7-annular protrusion, 8-neck flange.
Embodiment
See Fig. 1-2, a kind of rapid abutting joint pipe of the utility model, there is body 1, the two ends mouth of pipe 2 of body 1 is all connected with flange 3, the mouth of pipe 2 end face of flange plate end face 4 all with corresponding of described two flanges is concordant, and the flange plate end face 4 of described body 1 one side flange is provided with circular groove 6, and a sealing gasket 5 is provided with annular protrusion 7, the circular groove 6 of flange plate is in mating connection with the annular protrusion 7 of sealing gasket, and neck flange 8 tail end of described two flanges all welds with tube body wall.Making method: make wanted length ductile iron pipe according to customer requirement, again flange is carried out installing with ductile iron pipe interference fit after heating and flange plate end face is concordant with mouth of pipe end face, then neck flange tail end is welded, flange plate end face processing circular groove also mixes the sealing gasket being with annular protrusion, last according to requiring, the hydrostatic test, anticorrosive coat brushing, inspection, packaging warehouse-in are carried out to the ductile iron pipe processed.
