Abstract
The utility model relates to a steel-plastic connector for pipe, in particular to a connector for pipe used for connecting a steel pipe and a PE pipe. The utility model comprises a steel flange having a male thread, a PE flange and a steel sleeve having a female thread. The steel sleeve having an inner protruded edge is arranged at one end to engage with an outer protruded edge of the PE flange, and connected with the male thread of the steel flange at the other end. For further improving the sealed performance of the connection, a sealed gasket is provided between the steel flange and the PE flange. The utility model has the advantages of achieving pipe connection quickly, greatly enhancing the sealed performance of the connection, and satisfying the use demand of pipe with various diameters.
Description
One, technical field: the utility model relates to a kind of steel for pipe and moulds link, is specially adapted to the pipe joint that metallic conduit is connected with the PE pipeline.
Two, background technique: in plastic pipe and metallic conduit connection procedure, use steel to mould transition piece usually.For small-bore plastic tube (DN≤63), generally adopt the integral type steel to mould transition piece; For bigbore plastic tube (DN＞63), generally adopt steel-plastic flange to connect.Above-mentioned two kinds of steel are moulded the transition Placement, leak case often occurs at apposition position, have a strong impact on the normal use of pipeline.
Three, summary of the invention: the purpose of this utility model is exactly the defective that exists at prior art, provides a kind of and can connect fast, the steel for pipe of high-seal moulds link.
Its technological scheme is: comprise the steel bushing composition that has externally threaded steel flange, PE flange and have internal thread, wherein an end of steel bushing is provided with interior convex edge, cooperates with the outer convex edge of PE flange, and the other end of steel bushing is connected cooperation with the outside thread of steel flange.In order further to improve the sealing of apposition position, be provided with seal washer at the involutory surface of steel flange and PE flange.
Effect of the present utility model is to realize fast that pipeline connects, and the sealing of pipeline apposition position greatly improves simultaneously, can satisfy the general usage requirement of large and small bore pipe fitting.
Four, description of drawings: accompanying drawing is an a kind of embodiment's of the present utility model sectional structure chart.
Five, specific embodiment:
With reference to accompanying drawing, have externally threaded steel flange 1 and adopt stainless steel or plain carbon steel material, its involutory surface is provided with the convex edge, is processed with screw thread outside the convex edge, and removes the screw design of common flange plate.PE flange 3 adopts other plastic pipes such as polyethylene or PVC, is provided with the convex edge at its involutory surface, and removes the screw design of common flange plate.Steel bushing 2 adopts stainless steel or plain carbon steel material, and an end is provided with interior convex edge, cooperates with the outer convex edge of PE flange, and the other end is provided with internal thread and is connected cooperation with the outside thread of steel flange.In order further to improve the sealing of apposition position, be provided with seal washer (not drawing among the figure) at the involutory surface of steel flange 1 and PE flange 3.
The material that need to prove seal washer is selected can to select nitrile rubber class, ethylene propylene rubber class or other according to the material composition of line transportation.
For the ease of construction, be designed to circle or prismatic at steel flange, PE flange or steel bushing outer wall, so that be used with pipe wrench or spanner.
Claims (2)
