A kind of composite metal-plastic pipe port enhancing face seals and preparation method thereof, the composite metal-plastic pipe port enhancing face seals include metal enhancing ring and sealing ring, metal enhancing ring one end is equipped with flange, and the sealing snare is in the metal enhancing ring outer wall and is close to metal enhancing ring flange inner wall.The invention also includes the production methods of composite metal-plastic pipe port enhancing face seals.Utilize the present invention, it can be achieved that the sealing of composite metal-plastic pipe port enhancing and end face is prevented composite metal-plastic pipe port surface and directly contacted with water, it can be ensured that in the case where composite metal-plastic pipe long-term water flowing, plastic inner lining is not removed with inner wall of metal tube, is not cracked.
Description
Technical field
The present invention relates to a kind of composite metal-plastic pipe port enhancing face seals and preparation method thereof.
Background technique
Composite metal-plastic pipe because of it with good mechanical property, hygienic environment-protecting, low energy consumption, emptying effectiveness is high, operating cost
The features such as low, combines the advantage that metal tube and plastic tube share, and is widely used in the neck such as water supply, draining, blowdown, chemical industry
Domain.But composite metal-plastic pipe is under long-term water flowing environment, on the one hand, influence of the end face vulnerable to corrosion of metal, inner wall of metal tube
It will be slow and separate with plastic layer；On the other hand, the hot melt adhesive that composite metal-plastic pipe manufacturing process uses is in endface meeting
It reacts with water, is easy to lose adhesive property, and this influence will be promoted gradually into pipe, will also result in inner wall of metal tube
It is slowly separated with plastic layer.In spite of composite metal-plastic pipe be provided with port enhance ring, tube end face is protected
Shield, but still contact of the metal layer with plastic layer faying face with water near composite metal-plastic pipe end face can not so be blocked by appointing, and be passed through
Very long process and separate, after pipe network operation continues for some time, it may occur however that plastic inner lining falls off, and leads to line clogging,
Influence water flowing；Especially, after plastic inner lining falls off, inner wall of metal tube corrodes, when being applied to tap water conveying, corrosion
Metal tube is directly contacted with water, will seriously affect water supply quality.
Summary of the invention
The technical problems to be solved by the present invention are: in view of the above shortcomings of the prior art, it is multiple to provide a kind of metallo-plastic
Close pipe port enhancing face seals and preparation method thereof.
The technical solution adopted by the present invention to solve the technical problems is: a kind of composite metal-plastic pipe port enhancing end face
Sealing device, including metal enhance ring, are additionally provided with sealing ring, and the metal enhancing ring includes metal enhancing ring body, the gold
The one end for belonging to enhancing ring body is equipped with flange, and the sealing snare enhances ring outer wall and be close to metal enhancing ring in the metal to be turned over
Side inner wall.
Further, the section of the flange is the straight flange for enhancing ring body section perpendicular to metal, and the two constitutes L shape；
Alternatively, the section of the flange is the flanging for enhancing ring body section perpendicular to metal, the two constitutes class " u "-shaped.
Further, the metal enhancing ring body outer wall is equipped with embossing.
Further, the width of metal enhancing ring body is at least 10mm.
Further, the thickness of metal enhancing ring body is at least 0.5mm.
Further, the height of the flange is consistent with the wall thickness of composite metal-plastic pipe end face, or wraps metallo-plastic
The outer wall of compound pipe port.
Further, the sealing ring is rubber seal.
Further, the section configuration of the rubber seal is round, rectangle or trapezoidal；Or other shapes.
Further, the metal enhancing ring is that stainless steel enhances ring.
The production method of enhancing face seals in composite metal-plastic pipe port of the present invention, specifically includes the following steps:
S1, production metal enhance ring；
