Abstract

The utility model discloses a strenghthened type plastics pipe fittings, including pipe end and main part, the pipe end with the inner wall is smooth transition connection between the main part. The utility model discloses exchange piece under the overall leadership and carry out the institutional advancement for stress dispersion has improved extra strength and has supported, has strengthened PE plastics pipe fittings's the anti impact resistance of falling, avoids the pipe fitting in the easy breakage of stress concentration department, improves the security performance of pipe fitting mechanical properties and use. Compare with traditional pipe fitting, the utility model discloses the pipe fitting adopts injection moulding, and its advantage lies in: A, anti fall impact resistance and obviously improve, structure after b, the reinforcing does not influence pipe connections and uses, C, cost -push few, the price / performance ratio improves.

Description

Reinforced plastic pipe

Technical field

This utility model relates to municipal drainage pipe fitting technical field, especially a kind of reinforced plastic pipe, it is achieved pipe fitting anti-impact drop resistant performance improves, for municipal water supply and sewerage pipeline, building water supply and drainage and the pipe fitting of all kinds of protecting pipe of PVC/PE material.

Background technology

In recent years, along with infrastructure construction is increased input by deepening continuously of China's reform with national, the domestic demand to plastic conduit is always maintained at the speedup of average annual more than 15%, and especially in terms of the water supply and sewage pipeline network construction of city, plastic conduit plays the most important effect.

Compared with traditional cast-iron pipe, plastic conduit weight is lighter, and service life is longer, and in general the service life of plastic conduit is more than 50 years, has basically reached the service life equal with building.When having benefited from PVC/PE plastic pipe many advantages, also occur in that the pipe fitting matched does not has the high tenacity of tubing, resistance to impact and good scratch-resistant ability, so that whole pipe network exists hidden danger and deficiency, especially in special environment.

Utility model content

This utility model, for the deficiencies in the prior art, proposes a kind of reinforced plastic pipe, and structure is ingenious, and dispersive stress and offer extra force support, it is to avoid pipe fitting is broken at stress raiser, improves pipe fitting mechanical property and the security performance of use.

In order to realize above-mentioned utility model purpose, this utility model provides techniques below scheme: a kind of reinforced plastic pipe, including pipe end and main body, between described pipe end with described main body, inwall is that rounding off is connected.

Further, described main body wall thickness is more than the wall thickness of pipe end.

Further, described pipe end is provided with reinforcement with the junction outer wall of described main body.

Compared with prior art, this utility model has the advantage that and tradition pipe fitting is carried out structure improvement, stress is disperseed, improve extra force to support, enhance the drop resistant impact resistance of PE plastic pipe, avoid pipe fitting broken at stress raiser, improve pipe fitting mechanical property and the security performance of use.

Compared with tradition pipe fitting, this utility model pipe fitting uses injection mo(u)lding, has an advantage in that: a, drop resistant impact resistance significantly improve；B, enhanced structure have no effect on pipe fitting and connect use；C, cost increase seldom, and cost performance improves.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is sectional structure schematic diagram of the present utility model.

Detailed description of the invention

Being described in detail this utility model below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not have any restriction effect to protection domain of the present utility model.

A kind of reinforced plastic pipe as illustrated in fig. 1 and 2, including pipe end 1 and main body 2, in traditional structure, the inwall of pipe end 1 and main body 2 is tapering transition, in this product, the inwall of pipe end 1 and main body 2 is rounding off, the most not only enhance the mechanical property of pipe end 1 and main body 2, the stress having disperseed junction is concentrated, and makes the simple demoulding of processing easy, does not produce overlap.

As indicated by shading in figure 1, the outer layer of main body 2 thickeies, and strengthens the impact resistance at the broken position of pipe fitting.

The junction outer wall of pipe end 1 and main body 2 is equipped with reinforcement 3, and the internal stress not only making pipe fitting self is more dispersed, and protects and make pipe fitting the most easy to crack or broken when by external force.

This utility model is improved by structure, makes the drop resistant erosion-resisting characteristics of plastic pipe be greatly improved, so that pipe fitting safety durable performance when using installation improves.This pipe fitting is to be molded by PVC or HDPE raw material, mainly applies with collateral branch and the pipe fitting having camber, and the most all kinds of threeways, four-way, P is curved, S is curved.Because this kind of pipe fitting is easily concentrated at body junction or corner stress, it it is the place that is easily broken of pipe fitting.Not only solve, by this utility model, the problem that plastic pipe is breakable, and under the circumstances not improving cost, improve safety and the service life of pipe network, have the biggest economic worth and promotional value.

The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.

Claims

1. a reinforced plastic pipe, including pipe end and main body, it is characterised in that: between described pipe end with described main body, inwall is that rounding off is connected；Described pipe end is provided with reinforcement with the junction outer wall of described main body.

2. reinforced plastic pipe as claimed in claim 1, it is characterised in that: described main body wall thickness is more than the wall thickness of pipe end.
