Abstract
The utility model discloses a plastic -coated compound steel pipes is inserted to flexible straight mouthpiece of two rubber rings of double flute, including the steel pipe, the inner wall coating has thermoset epoxy, and the outer wall cladding has the thermoplasticity polyethylene. The utility model has the advantages of it is following: hold the external pressure than cast iron pipe and other socket joint type tubular product, interior pressure energy power is stronger, and is littleer to the geology influence of topography. The sealing performance that still can remain valid below 10% at the moulding deflection under the special circumstances exogenic action when the bell and spigot and not becoming invalid.
Description
Technical field
The utility model is related to steel pipe technical field, and the flexible straight mouthpiece of the double cushion rubber of especially a kind of double flute inserts plastic coated composite steel
Pipe.
Background technology
In order that spirally welded steel pipe, ERW, no seam welded tube and other class steel pipes, extend multi-field range of application, shadow
Ring the preservative treatment that the main link point one of metal welded tube application is steel pipe, second is the installation connected mode of steel pipe.
Utility model content
The utility model is directed to the deficiencies in the prior art, proposes a kind of flexible straight mouthpiece of the double cushion rubber of double flute and inserts plastic coated composite steel
Pipe, clever structure, easy to use.
In order to realize above-mentioned utility model purpose, the utility model provides technical scheme below：A kind of double cushion rubber of double flute is soft
Property straight mouthpiece insert plastic coated composite steel pipe, including steel pipe, inwall is coated with thermosetting epoxy resin, and outer wall is coated with thermoplastic poly second
Alkene.
Further, a termination is socket, and outer wall is provided with twice ring flat-bottom slot.
Further, a termination is the bellmouth mating grafting with socket, and bellmouth side wall is provided with two through holes, two through holes
Between twice ring flat-bottom slot.
Further, two through holes are 90 degree of potential difference settings of difference.
Compared with prior art, the utility model has advantages below：It is outer than cast iron pipe and other socket joint type tubing hold
Pressure, internal pressure capability are higher, and the matter influence of topography is less over the ground.When plastic deformation amount under the effect of special circumstances external force for the bell and spigot
Less than 10% still can keep effective sealing property not lose efficacy.
Brief description
Fig. 1 is the structural representation that the flexible straight mouthpiece of the double cushion rubber of the utility model double flute inserts plastic coated composite steel pipe.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in detail, the description of this part is only exemplary and explanatory,
Should not there is any restriction effect to protection domain of the present utility model.
As shown in figure 1, a kind of flexible straight mouthpiece of the double cushion rubber of double flute inserts plastic coated composite steel pipe, using plastic-coated mode, in steel pipe
Spray thermosetting epoxy resin powder macromolecular material, outer painting thermoplastic polyethylene's PE polymeric powder.Inside and outside anticorrosive coating is nontoxic, no
Evil, environmental protection and energy saving, serviceability is safe and reliable, and long perfomance life is reliable.
The installation connected mode design research and development of steel pipe are that the flexible straight mouthpiece of the double cushion rubber of double flute is inserted.Make the faster convenience of installation,
Improve installation effectiveness, save installation cost.Possess the anti-internal pressure of welded tube, external pressure by contrast it is adaptable to various topography work
Run under condition and use, be provided simultaneously with the feature performance benefit of other socket joint connection type tubing again.Can be widely applied to drinking water conveying,
The every field such as agricultural, chemical industry, cities and towns plumbing.
A kind of flexible straight mouthpiece of the double cushion rubber of double flute inserts plastic coated composite steel pipe novel tube, can be using spirally welded steel pipe, straight
Seam welded tube, seamless steel pipe are base tube, steel pipe body 1 two ends have been respectively adopted and have horizontally or vertically utilized diffusion of mould,
Or the socket joint connector of roll-forming.
Bellmouth adopts the expanding mold section of bellmouth, by the expanding shaping in wherein one end of 6 meters or 12 meters of length welded tubes or pipe fitting
For female end.Bellmouth form after expanding is as follows（Socket joint connection diagram）Shown；The other end adopts socket internal model, external mold, consolidates
Fixed circle, hydraulic jack move back the die assemblies such as mould accessory system, and disposable diffusion is shaped to socket end.
Socket form after diffusion, then be that the external diameter of socket 12 is matched with bellmouth 11 internal diameter, between for gap cooperation.Insert
Mouth 12 flat segments diffusions shaping twice ring flat-bottom slots are used for installing, position profile seal cushion rubber.As follows（Socket joint connection signal
Figure）Shown.Because being molded with diffusion using mould is expanding, can guarantee that the socket joint port fit clearance of every steel pipe is consistent, finally
The sealing property of energy each socket joint connector of effective guarantee.
It is provided with two screwed holes 111 in bellmouth 11 two seals groove center position, the top screwed hole is steam vent, side
Face screwed hole is pressurizing port.Achievable single port suppresses sealing property and the installation quality that socket joint connector is often located in inspection, ensures
The fixing quality control of whole piece pipeline.
Mould diffusion can guarantee that the profile and dimensional uniformity, standardization that bellmouth 11 is coupled with socket 12 and cushion rubber 2, has
Effect ensures bellmouth 11, socket 12, the compressed fit gap of profile seal cushion rubber 2, can guarantee that profile seal rubber sealing performance is pacified
Entirely reliable.
Anti-corrosion mode adopts plastic-coated mode, and the flexible straight mouthpiece of the double cushion rubber of double flute inserts interior spray heat after naked pipe preheats 260 ° 300 °
Thermoset epoxy resin powder macromolecular material, outer painting thermoplastic polyethylene's PE polymeric powder.Inside and outside anticorrosive coating all employs height
Molecular material, supporting advanced steel pipe inside and outside wall impeller blasting equipment and efficient coating equipment, the therefore inside and outside coating after application,
Possess good adhesion property and decay resistance；Inside and outside coating is nontoxic, harmless, environmental protection and energy saving, and serviceability is safe and reliable, makes
It is 30-50 with the life-span.
Research and development trial production seals single port bulge test by three groups of random sampling socket joints, and three groups of random sampling pipelines are overall
Water filling bulge test.Test pressure is 2.5Mpa, and 24 hours dwell times no revealed.
Can be suitable for common fluid pumped (conveying) medium pipeline, compare over traditional welded and installed, flange installation more can be significantly
Improve installation effectiveness, save installation cost cost, reduce the overall cost of pipeline.The straight mouthpiece of every flexibility is inserted port of steel pipe and is gone out
Before factory, prefabricated two liftings, hydraulic jack engaging lug is installed, construction and installation adopt Remote Mobile hydraulic station, oil cylinder, remote
The mode that journey straighforward operation controls, improves traditional manual cucurbit or euphroe mounting means.Have that installation rate is quick, peace
The advantage that packing quality is guaranteed, reduces labour intensity, save manpower financial capacity.
The flexible straight mouthpiece of the double cushion rubber of this double flute is inserted steel pipe corrosion-proof mode and is adopted plastic-coated mode, interior spray thermosetting epoxy resin
