Abstract
A reinforced electro-fused pipe fitting with a thermoplastic fiber prepreg tape belongs to the technical field of electro-fused pipe fittings. The reinforced electro-fused pipe fitting comprises a pipe fitting body, wherein a heating wire which is integrally molded with the pipe fitting body is arranged on the inner surface of the pipe fitting body, the two ends of the heating wire are respectively connected with binding posts arranged on the pipe fitting body, the thermoplastic fiber prepreg tape is arranged outside the pipe fitting body, and the thermoplastic fiber prepreg tape consists of a high-strength fiber layer and thermoplastic matrix resin arranged on the two sides of the high-strength fiber layer. As the thermoplastic fiber prepreg tape is directly combined with the pipe fitting body in a thermal fusion mode, the use of an adhesive is avoided, the manufacture technology of the fiber-reinforced pipe fitting is simplified, the cost is lowered, and the performance is reliable. Besides, as the two sides of the high-strength fiber layer in the thermoplastic fiber prepreg tape are protected by the thermoplastic matrix resin made of the same materials with the pipe fitting body, the strength of the electro-fused pipe fitting is increased, and meanwhile, the fiber layer is protected from damage in the transport, installation and use processes of the pipe fitting. The pipe fitting with more reliable and stable performance is suitable for popularization and application.
Description
Technical field
The utility model belongs to the electric melting pipe fittings technical field, is specifically related to a kind of intensity raising, stable performance, the simple thermoplastic fiber preimpregnation of technology band enhancing electric melting pipe fittings.
Background technique
In the prior art, in bigbore plastic composition pipeline be connected to the master with electrothermal smelting tube, along with the development of mesohigh plastic composition pipeline, tubing is more and more higher to the requirement of strength of electric melting pipe fittings in recent years.For realizing the intensity enhancing with traditional electric melting pipe fittings, it mainly is the mode that relies on Steel Skeleton to strengthen, there is interface problem between the plastics that its problem of bringing is Steel Skeleton and electric melting pipe fittings, in the pipe fitting using process, very easily cause enhancement layer to lose efficacy, and because the existence of metal, in use pipe fitting corrodes easily.(application number: 201120348673.8) mention the outside coating reinforced fiber of a kind of body, reinforcing fiber is by the bonding enhancement mode electric melting pipe fittings of binding resin and body for Chinese patent " a kind of fiber reinforcement type electric melting pipe fittings ".The problem of this kind electric melting pipe fittings is: stick with glue knot between fiber and the body, higher to technological requirement, the pipe fitting cost increases; All may exist compound by different materials or interlaminar resin between body and glue, glue and the enhancement layer and interface that produce, the existence at interface may make enhancement layer not bring into play maximum effect or inefficacy; Reinforcing fiber exposes on the pipe fitting surface, and fiber-reinforced layer is worn easily and damages in transportation installation and using process, causes enhancement layer to lose efficacy.
The model utility content
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of intensity raising, stable performance, the simple thermoplastic fiber preimpregnation of technology band to strengthen electric melting pipe fittings.
Described a kind of thermoplastic fiber preimpregnation band strengthens electric melting pipe fittings, comprise the pipe fitting body, described pipe fitting body internal surface arranges electric heating wire integrated with it, the electric heating wire two ends respectively be arranged on the pipe fitting body on wiring terminal link to each other, it is characterized in that described pipe fitting body arranges thermoplastic fiber preimpregnation band outward, described thermoplastic fiber preimpregnation band is made of high strength fibre layer and the thermoplastic matrix resin that is arranged on high strength fibre layer both sides, and the thermoplastic matrix resin is identical with pipe fitting body material.
Described a kind of thermoplastic fiber preimpregnation band strengthens electric melting pipe fittings, it is characterized in that being equipped with the welding peep hole on the described pipe fitting body.
Above-mentioned a kind of thermoplastic fiber preimpregnation band strengthens electric melting pipe fittings, comprise the pipe fitting body, described pipe fitting body internal surface arranges electric heating wire integrated with it, the electric heating wire two ends respectively be arranged on the pipe fitting body on wiring terminal link to each other, the pipe fitting body arranges thermoplastic fiber preimpregnation band outward, and described thermoplastic fiber preimpregnation band is by the high strength fibre layer and be arranged on the high strength fibre layer both sides thermoplastic matrix resin identical with pipe fitting body material and constitute.The utility model has been avoided the use of adhesive by thermoplastic fiber preimpregnation band and pipe fitting body is directly compound by hot melting way, makes that fiber reinforcement pipe fitting intensity improves, simplified manufacturing process, saves cost; And there is the matrix resin layers protection identical with pipe fitting body material the middle high strength fibre layer both sides in the thermoplastic fiber preimpregnation band; therefore fiber preimpregnation band is when having improved electric melting pipe fittings hoop intensity; also having avoided pipe fitting fiber-reinforced layer in transportation installation and using process to be subjected to external environment destroys; make its performance reliable more and stable, be suitable for applying.

Embodiment
The utility model will be further described below in conjunction with Figure of description:
Shown in Fig. 1-2, a kind of thermoplastic fiber preimpregnation band strengthens electric melting pipe fittings, comprise pipe fitting body 1, described pipe fitting body 1 internal surface setting electric heating wire 5 integrated with it, electric heating wire 5 two ends respectively be arranged on pipe fitting body 1 on wiring terminal 4 link to each other, be used for heating, make tubing and pipe fitting body of the present utility model 1 fusion, the described pipe fitting body 1 outer thermoplastic fiber preimpregnation band 2 that arranges, described thermoplastic fiber preimpregnation band 2 is made of high strength fibre layer 7 and the thermoplastic matrix resin 6 identical with the pipe fitting bulk material that be arranged on high strength fibre layer 7 both sides.
For the ease of observing the fusion situation of tubing and pipe fitting body 1, the utility model is equipped with welding peep hole 3 at pipe fitting body 1, in tubing and pipe fitting body 1 alloying process of the present utility model, after 1 fusing of pipe fitting body, the molten slurry of part is packed into the welding peep hole 3 from welding peep hole 3 the inners, is used for observing both fusion states.
As shown in Figure 2, thermoplastic fiber preimpregnation band 2 of the present utility model is made of high strength fibre layer 7 and the thermoplastic matrix resin 6 that is arranged on high strength fibre layer 7 both sides, high strength fibre layer 7 can be glass fibre, aramid fibre etc., thermoplastic matrix resin 6 is identical with the material of pipe fitting body 1, the outer surface of thermoplastic fiber preimpregnation band 2 by its thermoplastic matrix resin identical with the pipe fitting bulk material 6 and pipe fitting body 1 is bonded as one after by heating and melting, avoided binding resin, when improving pipe fitting intensity, simplify manufacturing process, saved cost; And because thermoplastic matrix resin 6 is identical with the material of pipe fitting body 1,1 of thermoplastic fiber preimpregnation band 2 and pipe fitting body do not exist because the interface problem of the compound generation of different materials, thereby when having strengthened the electric melting pipe fittings performance, make it reliable more and stable.
