Abstract
The utility model relates to a novel hot melt socket connection plastic pipe fitting. At least one end of the pipe fitting is provided with an annular socket port, which is provided with an outer ring and an inner ring. The outer ring adopts the same material as the pipe fitting, and an inner diameter of the outer ring is equal to an inner diameter of the socket port of the hot melt socket connection plastic pipe fitting having the same specification. An inner side of an end port of the outer ring is provided with a chamfering toward the outer side of the pipe fitting. The inner ring is a thin-wall copper ring, and an outer diameter of the inner ring is equal to an inner diameter of the plastic pipe having the same specification. An outer side of an end port of the inner ring is provided with a chamfering toward the inner side of the pipe fitting. An axial length of an upper segment of the inner ring is exposed out of an end port of the outer ring by 1 to 2mm. On a bottom part of the socket port, 2 to 4 exhaust holes are uniformly disposed on the inner ring along the axial direction, and two observation holes arranged relatively to the exhaust holes in a staggered manner are symmetrically disposed in the outer ring along the axial direction. The utility model is advantageous in that the connection part between the pipe fitting and the pipeline has no inner flange, and no head loss is generated, when the water flows through the connection part; when the pipe fitting and the pipeline are in a hot melt socket connection, the air in the socket port can be exhausted by the exhaust holes, no inveracious soldering can be generated on the bottom part of the socket port, and no bubbles can be formed on the welding connection surface of the pipe wall, therefore the welding quality can not be affected.
Description
Affiliated technical field
The utility model relates to a kind of plastic pipe that prevents and is making the novel plastic pipe fitting that forms in-flanges when thermofusible spigot connects.
Background technique
Existing plastic pipe can cause loss of head doing the in-flanges that forms when thermofusible spigot connects.Especially be in the terminal life of the city planting ductwork pipe of registering one's residence; The plastic water supply pipes that adopt more, wherein a large amount of all employings thermofusible spigot Placements connect, and the in-flanges that the joint forms when thermofusible spigot connects has had a strong impact on terminal use's hydraulic pressure; In order to guarantee terminal use's hydraulic pressure; Just must pressurize, improve energy consumption thus, strengthen the cost of water undertaking to city planting ductwork.
Summary of the invention
In order to address the above problem, the utility model provides a kind of plastic pipe that prevents making the novel plastic pipe fitting that forms in-flanges when thermofusible spigot connects.
The utility model realizes that the technological scheme that above imagination is adopted is: the end that has at least adopting heat to melt the plastic pipe that the socket joint mode connects has an annular socket, and bellmouth is provided with outer shroud and interior ring.Outer shroud is and the ring of pipeline with material, and bore diameter of outer ring equals the internal diameter that the same specification thermofusible spigot connects the plastic pipe bellmouth, and inboard, outer central port has towards the chamfering in the pipe fitting outside; Interior ring is the thin-walled copper ring, and its external diameter equals the internal diameter of same specification plastic tube, and the outside, interior central port has towards the inboard chamfering of pipe fitting.Interior ring epimere axial length slightly is longer than outer shroud, and interior ring hypomere firmly is connected with the pipe fitting plastic liner.The degree of depth of annular socket is consistent with the bellmouth degree of depth of existing same specification plastic pipe.In bellmouth bottom, on interior ring, radially evenly be provided with 2-4 exhaust port, staggering radially and with the exhaust port position at outer shroud is arranged with 2 peep holes.
Adopt the plastic pipe of the utility model manufacturing to have following remarkable result: ring is the thin-walled copper ring in the pipe fitting, can not produce the loss of flood peak because of the heating and melting undergauge; Pipe fitting and pipeline junction can not form in-flanges, and water flows through does not have the head loss here; Pipe fitting and pipeline are carrying out hot melt spigot-and-socket when being connected, and the air in the bellmouth is discharged by steam vent, can make the welding of plastic tube end face and bellmouth bottom good, can not produce rosin joint in the bellmouth bottom and at tube wall solder side formation bubble, thereby influence welding quality; Can be observed when doing hot melt spigot-and-socket and connecting from peep hole, whether pipeline is inserted into the position, thereby guarantees welding quality.
Description of drawings
Fig. 1 passes through the sectional view of the section of bellmouth medial axis and peep hole medial axis simultaneously for the utility model.
Encircle ring chamfering 9. peep holes in the hypomere 7. outer shroud chamferings 8. in ring epimere 4. exhaust ports 5. bellmouths 6. in 1. pipe fittings, 2. outer shrouds 3. among the figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, have an annular socket (5) at the end that has at least that adopts heat to melt the plastic pipe (1) that the socket joint mode connects, bellmouth (5) is provided with outer shroud (2) and interior ring.Outer shroud (2) is and the ring of pipeline with material, and outer shroud (2) internal diameter equals the internal diameter that the same specification thermofusible spigot connects the plastic pipe bellmouth, and outer shroud (2) port inboard has towards the chamfering (7) in pipe fitting (1) outside; Interior ring is the thin-walled copper ring, and its external diameter equals the internal diameter of same specification plastic tube, and the outside, interior central port has towards the inboard chamfering (8) of pipe fitting (1).Interior ring epimere (3) axial length grows outer shroud port one-2mm, and interior ring hypomere (6) firmly is connected with pipe fitting (1) plastic liner.The degree of depth of annular socket (5) is consistent with the bellmouth degree of depth of existing same specification plastic pipe.In bellmouth (5) bottom, on interior ring, radially evenly be provided with 2-4 exhaust port (4), staggering radially and with exhaust port (4) position at outer shroud (2) is arranged with 2 peep holes (9).
Pipe fitting (1) and pipeline are carrying out thermofusible spigot when being connected, and the air in the bellmouth (5) is discharged through exhaust port (4).The joint can not form in-flanges, just can therefore not produce loss of head yet.
Claims (2)
