Abstract
The utility model provides a full anti-corrosion joint core, which belongs to the technical field of sealing a composite pipe joint and overcomes shortcomings that when a conventional anti-corrosion lining pipe is connected into a pipeline, a metal outer layer of the conventional anti-corrosion lining pipe is easily corroded to pollute fluid media in the pipeline and shorten service life of the pipeline. The full anti-corrosion joint core is characterized by comprising a pipe-shaped imbedded piece which is provided with an imbedded section and an extension section, wherein the outer surface of the imbedded section is a circular conical surface with a small front end and a big rear end, a seal ring is arranged on the imbedded section, and a gasket is arranged on the extension section. The full anti-corrosion joint core can seal the inside of a joint of an anti-corrosion lining pipe to prevent the same from being corroded by liquid media inside the anti-corrosion lining pipe, thereby ensuring that the liquid media inside the pipeline can not be polluted due to corrosion of the metal outer layer and prolonging service life of the pipeline.
Description
Technical field
The utility model relates to a kind of sealing of composite pipe interface, particularly a kind of interface fuse that the composite pipe interface connection that is used for systems such as draining, air feed, chemical industry, heating power is sealed.
Background technique
Mostly traditional running water pipe and pipe fitting are welding galvanized pipe and zinc-plated casting pipe, easily corrosion, therefore replaced by the plastic tube that connects by hot melt, composite metal-plastic pipe and plastic pipe gradually, but the intensity of the pipeline that connects into is relatively poor, it is easily impaired to be subjected to external force.
Using at present more is the plastics lined pipe that is composited by metal outer and inner plastic and the metal composite pipe that is composited by uncorruptible metal internal layers such as metal outer and stainless steel, copper, both are big because of having the metal outer join strength, stressed be difficult for impaired, has preferable antisepsis because of having uncorruptible internal layer (plastics, stainless steel and copper etc.) again, quite be subjected to market favor (for convenience of description, hereinafter with corrosion-proof lining pipe general designation plastics lined pipe and metal composite pipe).When connecting into pipeline by pipe fitting, no matter pipe fitting is any material, the metal outer of corrosion-proof lining pipe always can contact with the flowing medium in the pipe fitting and be corroded, especially under coupled condition, this metal outer has externally threaded appearance flowing medium inevitable with end face and in the inner chamber and contacts, this part becomes the starting point that whole metal outer is corroded, and then pollutes ducted flowing medium, also can shorten the working life of pipeline.
Summary of the invention
The purpose of this utility model is, a kind of complete anticorrosion interface fuse is provided, this complete anticorrosion interface fuse can seal the inside of the interface of corrosion-proof lining pipe, the defective that metal outer easily is corroded and pollutes ducted flowing medium and shorten the working life of pipeline when solving existing corrosion-proof lining pipe and connecting into pipeline.
The purpose of this utility model realizes by following technical proposal: a kind of complete anticorrosion interface fuse, it is characterized in that, this interface fuse comprises imbedding piece in a tubular form, this imbedding piece has the section of inserting and extension section, the outer surface of the described section of inserting is a conical surface and front end is little, the rear end is big, dispose seal ring on the described section of inserting, dispose sealing gasket on the described extension section.
This complete anticorrosion interface fuse is arranged in composite pipe and the pipe fitting, and the extension section with sealing gasket is inserted in the pipe fitting, and the section of inserting with seal ring is inserted in the corrosion-proof lining pipe.Because the outer surface of the section of inserting is a conical surface and front end is little, the rear end is big, the external diameter of the control section of inserting is slightly less than the internal diameter of corrosion-proof lining pipe as making its front end external diameter, make its rear end external diameter be slightly larger than the internal diameter of corrosion-proof lining pipe, then the section of inserting is inserted in the corrosion-proof lining pipe and can forms drive fit with the corrosion-proof lining pipe, seal ring is squeezed between the corrosion-proof lining pipe and the section of inserting, make corrosion-proof lining pipe and pipe fitting be connected when tightening by screw thread, imbedding piece can rotate with the corrosion-proof lining pipe, avoids damaging seal ring; Make the section of inserting and corrosion-proof lining pipe form sealing by seal ring, prevent that the flowing medium in the corrosion-proof lining pipe from touching metal outer.While corrosion-proof lining pipe can promote imbedding piece is pressed on the pipe fitting sealing gasket on the extension section, forms sealing, prevents that the flowing medium in the pipe fitting from touching the metal outer of corrosion-proof lining pipe.The comprehensive sealing of carrying out is carried out in being connected by two above-mentioned sealing configurations of corrosion-proof lining pipe and pipe fitting, prevents that metal outer is corroded.
In above-mentioned complete anticorrosion interface fuse, the adjoiner of described section of inserting and extension section has step.Be used for sealing gasket is formed support, guarantee good sealing effect.
In above-mentioned complete anticorrosion interface fuse, described extension section is provided with metallic shim, and this metallic shim is between sealing gasket and step.Metallic shim can rotate on the extension section, when tightening corrosion-proof lining pipe and pipe fitting, metallic shim forms sealing gasket and supports and rotate with respect to the extension section, make sealing gasket contact pipe fitting and remain static with respect to sealing gasket, thereby avoid sealing gasket is caused the rotation wearing and tearing even damages the assurance sealing effect.
In above-mentioned complete anticorrosion interface fuse, the described section of inserting is provided with groove, and above-mentioned seal ring is arranged in the groove.
In above-mentioned complete anticorrosion interface fuse, described imbedding piece adopts uncorruptible metallic material to make.
Compared with prior art, when the corrosion-proof lining pipe connects into pipeline by pipe fitting, complete anticorrosion interface fuse of the present utility model is connected in corrosion-proof lining pipe and the pipe fitting, thereby when connecting, make seal ring and corrosion-proof lining pipe on the section of inserting form sealing, sealing gasket on the extension section and pipe fitting form sealing, thereby the inner chamber of metal outer and pipe fitting and corrosion-proof lining pipe is isolated fully, avoid by wherein flowing medium corrosion, guarantee that thus ducted flowing medium can not polluted because of metal outer is corroded, and can also prolong the working life of pipeline.
