Abstract
A steel plastic transitional pipe fitting comprises a stainless steel pipe, a locking ring and a plastic pipe fitting, wherein a flaring plug is arranged at one end of the stainless steel pipe; a through hole and a convex groove are radially formed in the pipe wall of the flaring plug; the flaring plug is inserted into the pipe wall of the plastic pipe fitting formed by injection molding and is fixedly connected with the pipe wall of the plastic pipe fitting in an embedded way; and the locking ring corresponds to the flaring plug of the stainless steel pipe in a plastic pipe fitting hole and is tightly and fixedly connected with the inner wall of the pipe hole. According to the steel plastic transitional pipe fitting, pipes made of two different materials, namely the stainless steel pipe and the plastic pipe are connected, so that favorable pulling and falling resistance and bending resistance are obtained; and a transitional interface retains excellent air-tightness.
Description
Technical field
The present invention relates to a kind of Stainless Steel Tube and the pipeline parts that connects is refuted in the plastic tube transition, particularly a kind of steel is moulded transition fitting.
Background technique
Stainless Steel Tube has obtained in the combustion gas transmission and distribution network to use in building.And to a large amount of use of the Urban Buried Pipeline Network of building delivery of fuel gas polyethylene (PE) tubing.At present, the problem of connecing is refuted in the transition that does not also have a kind of reliable element to solve Stainless Steel Tube and buried polyethylene pipe.Become problem demanding prompt solution in the application.
Summary of the invention
The purpose of the utility model is to design a kind of steel and moulds transition fitting, uses this pipe fitting that the tubing of two kinds of different materials of Stainless Steel Tube and plastic tube is connected to have that good tension is taken off, counter-bending ability and transition interface good air-tightness.
The technological scheme of the utility model is: a kind of steel is moulded transition fitting, by Stainless Steel Tube, and locking ring; Plastic pipe constitutes; It is characterized in that: an end of Stainless Steel Tube is the reaming plug, radially is provided with through hole and emboss pit on the tube wall of reaming plug, and the reaming plug is embedded affixed in the tube wall of the plastic pipe of molding and forming; Locking ring reaming plug with Stainless Steel Tube in the plastic pipe pore is corresponding, closely is connected with the pore inwall.
Present technique has designed special ports with the Stainless Steel Tube end, rabbets in length and breadth with the pipe fitting of molding and forming, has formed good tension and has taken off and counter-bending ability, and the locking ring that the interference state embeds has down guaranteed the tightness of transition interface.It is as shown in Figure 1 that the plastic tube connecting end can be designed to hot melt butt joint form, or the electric smelting Connecting format is as shown in Figure 2.

Fig. 1 moulds the transition fitting structural representation for the steel of hot melt dock.
Fig. 2 moulds the transition fitting structural representation for the steel of electric smelting jointing type.
Fig. 1 plastic pipe, 2 locking rings, 3 through holes, 4 emboss pits, 5 Stainless Steel Tubes.
Embodiment
Steel is moulded transition fitting, by Stainless Steel Tube 5, and locking ring 2; Plastic pipe 1 constitutes, and an end of Stainless Steel Tube is processed into the reaming plug, radially is processed with through hole 3 and emboss pit 4 on the tube wall of reaming plug; The reaming end is put into the plastic pipe 1 of ability of injection mould molding and forming and polyethylene (PE) pipe welding, and Stainless Steel Tube 5 and plastic pipe 1 have improved the reliability that connects in joint interlocking in length and breadth each other; Durability; Locking ring 2 adopts the stainless-steel pipe processing of same specification, and locking ring embeds pore by the polyethylene tube end under the interference state, constitutes with the pore inwall closely to be connected; Locking ring reaming end with Stainless Steel Tube in the plastic pipe pore is corresponding, so locking ring has guaranteed the tightness of transition interface.It is as shown in Figure 1 that the plastic pipe connecting end can be designed to hot melt butt joint form, or the electric smelting Connecting format is as shown in Figure 2.
