Description
Technical field
It the utility model is related to a kind of port enhancing ring inner lining plastic tube spigot-and-socket metal tube.
Background technology
Inner lining plastic tube spigot-and-socket metal tube, because of its good mechanical property, hygienic environment-protecting, energy consumption is low, emptying effectiveness is high, operation
The advantages that cost is low, service life is long, ambient adaptability is strong, is the pipeline being most suitable at present for tap water conveying.Lining plastic
The plastic layer of tubing both ends of the surface and metal bonding layer are firm after expects pipe spigot-and-socket metal tube completes, and the short time uses process
It is comparatively safe, but when tubing usage time is long or is stacked at outdoor for a long time, the metal layer of both ends of the surface can produce certain corrosion,
Cause the plastic layer of tubing both ends of the surface to produce with metal layer to separate, while the collective effect of the tension produced is shunk in plastic layer
When, plastic layer area separated with metal layer is increasing, and flange blocks under the action of plastic layer may finally be caused to have waterpower
Pipeline, influences pipeline normal water supply, and plastic layer produces the position of layering with metal layer, and water is directly contacted with metal, and water quality is produced
Life seriously affects.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of plastic tube and metal tube lamination problem of solving
Port strengthens ring inner lining plastic tube spigot-and-socket metal tube.
Technical solution is used by the utility model solves its technical problem：A kind of port enhancing ring inner lining plastic tube is held

Compared with prior art, the beneficial effects of the utility model are：
1. the structure solution plastic tube that inner lining plastic tube spigot-and-socket metal tube is generally adopted by hot melt adhesive is glued with metal tube
The problem of connecing, hot melt adhesive can reach the abundant Nian Jie of plastic tube and metal tube in a short time；But the time is grown, and is especially disliked
Bad environment, such as exposes to the sun and rain outside for a long time, or extremely cold or very hot area, containing soda acid or has other chemistry in pumped (conveying) medium
When corrosion, hot melt adhesive is easy to aging, causes plastic tube to be layered with metal tube, can thus block water pipe, also just make
The secondary pollution of Cheng Shui, strengthens ring using port, can be fully solved the problem of plastic tube is layered with metal tube.
2. inner lining plastic tube spigot-and-socket metal tube, its connection mode are bayonet joints, to the bellmouth and socket of tubing
Circularity it is more demanding, port increase enhancing ring, add the intensity of metal tube faucet and socket, can preferably solve metal
Pipe is easily deformed in the case where transportational process, cargo handling process, installation process etc. by external force because being acted on, cause installation difficulty compared with
Greatly, not the problem of or even not installing.
3. increase enhancing ring, can be fully solved the problem of plastic tube is layered with metal tube, it is possible to reduce hot melt adhesive
Usage amount, while the thickness of plastic tube also can accordingly be thinned, and more save material, reduce cost, be computed drawing saving
Material cost strengthens the cost difference of ring more than 60% with increase.
4. due to inner lining plastic tube spigot-and-socket metal tube because the metal wall thickness of bellmouth and socket is inconsistent, in tubing plus
The temperature of hot compound tense, bellmouth and socket is difficult control, so plastic tube difficulty maximum Nian Jie with metal tube is the two of tubing
Port, therefore product qualification rate is relatively low, cost is very high, and increase enhancing ring can be fully solved that pipe end is not bonding to cause plastics
Pipe and metal tube lamination problem, also substantially increase the product qualification rate of inner lining plastic tube spigot-and-socket metal tube, greatly reduce
Material cost and productive manpower cost.Also it is exactly that the substandard product of inner lining plastic tube spigot-and-socket metal tube is difficult processing, such as
Plastics and metal separation costs are very high, lose more than gain, generally take two methods, one kind is when old metal is sold by it
Fall, the method price is extremely low, and cost is higher；Two kinds are to burn its plastics, stay its metal tube to be continuing with, although the method into
This is low compared with first method, but environmental pollution is larger.So increase enhancing ring also rises while product qualification rate is improved
Energy-saving, environmental protection effect is arrived.
5. the utility model uses the technical solution that enhancing ring is installed to inner lining plastic tube spigot-and-socket metal tube two-port, prevent
Stop inner lining plastic tube spigot-and-socket metal tube ectonexine and produced layering, effectively maintain inner lining plastic tube spigot-and-socket metal pipe structure
Stability and integrality.
6. the utility model controls enhancing ring tensioner ring by controlling inner lining plastic tube spigot-and-socket metal pipe outside diameter deflection
Deflection, especially first passes through the expanding equipment of control or the automatic positioning of pipe expanding equipment pressure calculates inner lining plastic tube spigot-and-socket gold
Belong to bore or outside diameter, then set definite value is increased to by the tube expansion mould outside diameter of pipe expanding equipment or expanding equipment（Need to increase
The deflection of inner lining plastic tube spigot-and-socket metal tube body）And reach the technical solution of the deflection of stainless steel enhancing ring, both protected
It is firm, firm to have demonstrate,proved the installation of enhancing ring, and has prevented the excessive caused tubing cracking of inner lining plastic tube spigot-and-socket metal tube deformation
And tubing installation difficulty, while solve pipe expanding equipment or expanding equipment pressure size be unable to control wall thickness it is not of uniform size,
The non-round inner lining plastic tube spigot-and-socket metal pipe expanding annular strain amount size issue of tubing.
7. the utility model waits pipe expanding equipment or expanding equipment using metal tube enlarged outside diameter 1-2mm during enhancing ring tensioner ring
When being stopped, metal tube can bounce back rapidly, and strengthen ring expanded joint on plastic tube top layer, and plastic tube produces deformation 0.1mm-
1mm, so strengthens ring and utilizes compression firmly supporting plastic pipe port, so as to solve the problems, such as that plastic tube is layered with metal tube.
8. the utility model puts ring using manipulator, flattening device will strengthen ring and inner lining plastic tube spigot-and-socket metal pipe end opening
Concordant technical solution, production efficiency is high, and institute's converted products stable quality is reliable.
9. the utility model carries out the technical solution of preservative treatment using zinc rich paint to installing enhancing ring, liner can be improved
The interior antiseptic property of plastic tube spigot-and-socket metal tube, extends the service life of inner lining plastic tube spigot-and-socket metal tube, makes enhancing ring
Effect it is further notable.
