Compared with the prior art, its beneficial effect is embodied in:
1, the enlarging parts among the present invention are because employing independently is provided with the injection moulding member, make full use of the relative stability of moulding size, also can utilize simultaneously injection moulding member independence machining characteristics, can require that according to the difference of functional part corresponding construction is set and satisfy usage requirement, guarantee the Watertightness energy of tubing socket joint.
2, Placement of the present invention can effectively reduce the product link cost by alleviating the use amount of product weight and minimizing auxiliary equipment.
3, the present invention is on the mounting type that straight tube connects, and is convenient and swift, is easy to adjust.
4, the present invention passes through at injection moulding enlarging outer installment stiffening rib, and the thickening of enlarging tube wall is provided with, and can effectively guarantee the intensity of enlarging functional part.
5, the present invention is by enforcement and through closed-water test, and the result meets country about the requirement of closing the water test stone among " water and wastewater piping engineering construction and acceptance specification " GB50268-1997.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an injection moulding flared pipe fitting structural representation of the present invention.
Fig. 3 is the single-ended welding schematic representation of the invention process.
Fig. 4 is single-ended welding schematic representation for the present invention finishes.
Number in the figure: 1 left end straight length, 2 right-hand member straight lengths, 3 injection moulding flared pipe fittings, 4 end mouths, 5 enlargings, 6 hoop stiffening ribs, 7 walings, 8 ring-type chassis, 9 bayonet sockets, 10 thickened wall, 11 weldering plates.
Below by embodiment, the invention will be further described in conjunction with the accompanying drawings:
Embodiment:
Referring to Fig. 1, Fig. 2, in the present embodiment, the material of being taken over that is positioned at two ends is straight length, be left end straight length 1 and right-hand member straight length 2, be connected between the straight length of two ends is the independent injection moulding flared pipe fitting 3 that is provided with, the heat that forms between the end mouth 4 of injection moulding flared pipe fitting 3 and the left end straight length on the end face is melted welding, is connected with the socket joint formation socket joint of right-hand member straight length 2 in enlarging 5 between the enlarging 5 of injection moulding flared pipe fitting 3 and the right-hand member straight length 2.
In concrete the enforcement, the corresponding structure setting also comprises:
Injection moulding flared pipe fitting 3 is a material of the same race with right-hand member straight length 1 and right-hand member straight length 2.
Shown in Figure 2, be the counterface welding, on the end of injection moulding flared pipe fitting 3 mouth end face, the ring-type chassis 8 that the double-wall corrugated pipe end face of setting and left end straight length 1 matches cooperates the welding end surface of double-wall corrugated pipe madial wall to be provided with bayonet socket 9 on the welding end surface on ring-type chassis 8.
