Description
Technical field
This utility model is related to pipeline connection area, more particularly to a kind of anti-corrosion attaching type RTP pipe fitting.
Background technology
Reinforced thermoplastics pipe (Rein-forced Thermoplastic Pipe, abbreviation RTP) it is generally main by
Three layers of composition, i.e., inside and outside plastic layer and be arranged on the enhancement layer that is composited by reinforcing material of centre.RTP is held due to which
Pressure energy power is high, equal caliber cost performance is high, linear expansion coefficient is little, it is flexible the features such as, application constantly expands.Get at present
To be applied to more the industries such as hot spring water delivery, high pressure water injection, due to the particularity of application scenario, thus to its necessary
Requirement is often higher than common pipe fitting, and wherein, how to improve pipe fitting antiseptic property and reduces cost is that such pipe fitting is used
Key point.
Prior art is typically with strengthening electric melting sleeve or attaching type for the connection strengthened between thermoplastic composite tube
What pipe fitting was carried out.Electric melting sleeve itself by plastics bonding forming connection and sealing, there is intensity is relatively low, construction infection is big etc.
Shortcoming, is generally used for the mesolow occasion such as hot spring water delivery, and connection of the using fresh herb between high pressure water injection reinforced pipe.With electric smelting
Sleeve is compared, and attaching fitting is that the outer surface to tubing is extruded and formed sealing, this connected mode good reliability, energy
Enough to form preferably sealing to end face, bearing capacity is high, and construction affects little to bonding strength, thus range of application is wider.
At present, the anti-corrosion measure of prior art attaching fitting be mostly by the way of lining plastic, such as plastic-coated malleable cast iron pipe fitting,
Lining plastic malleable cast iron pipe fitting, but this kind of pipe fitting typically do not used at relatively high temperatures, and in work progress, the plastics that lining is gone due to because
For the difference of thermophysical property, cause As time goes on, bonding portion gradually decrease and be difficult to make metal and plastics this two
Plant material to be integrated, be susceptible to obscission, along with the distinctive creep propertieses of plastics, therefore in delivery and water filling
Using central, the drawbacks described above of prior art attaching fitting then becomes apparent from.So that people are to produced by its life-time service
Interfacial separation phenomenon is worried, so as to have impact on the use of line plastic-steel tube system to a certain extent.It is especially high in fluid
Under the conditions of frictional force, plastic lining pipe fitting is more difficult to the connection of competent pipeline.Additionally, prior art also adopts all steel
Pipe fitting and coating enamel pipe fitting.But all steel pipe fitting cost is at a relatively high, most of day for being simply applied to pipe with small pipe diameter
The connection of conventional water plastic tube or stainless-steel pipe;And the technology of enamel is coated, as enamel is to having high demands during use
Feature, thus it is only limitted to the connection of socket pipe member, clasp pipe fitting etc., it is impossible to outer for attaching fitting puts, and limits
The further genralrlization application of the technology.

Further, the lateral surface of the core pipe is provided with back-off tooth, and the inwall of the overcoat is provided with groove and and core
The back-off tooth correspondence of pipe.
Further, the end face of the connection end of the core pipe is provided with sealing ring.
The beneficial effects of the utility model are:The rubber hot melt layer on surface can effective protection internal structure, make metal with
Air exclusion, and frictional force can be provided, convenient to install, rubber is adopted outside hot-melt technology coating outer cover and core pipe, with reference to tight
It is close, and as rubber itself has retractility, be not readily separated during temperature change and come off, the zinc coat on sleeve pipe and core pipe can be replaced
It is lost for interior metal, increases pressure welding pipe fittings service life, core pipe inwall is provided with enamel layer, forms comprehensive anticorrosion structure, and
Reduce the surface roughness of core pipe inwall, fine heat-resisting performance.
