Description

A kind of PE pipe fittings

Technical field

This utility model is related to PE pipe fitting technical fields, more particularly to a kind of PE pipe fittings.

Background technology

Pipe fitting is the general designation of the parts for playing the effects such as connection, control, break-in, shunting, sealing, support in tubing, It is, by the important component part of pipe connecting line, socket fitting, threaded fitting, flanged fitting can be divided into according to method of attachment With the class of weld-end fittings four.And PE pipe fittings are a kind of novel pipe fittings, it have high tenacity, it is corrosion-resistant, nontoxic the features such as, be difficult to let out Leakage, but existing connecting pipe intensity is not high, the yielding cracking of life-time service, and user then wishes that comprcssive strength is the bigger the better, Need to improve.

Utility model content

The purpose of this utility model is and a kind of PE pipe fittings for proposing in order to solve shortcoming present in prior art.

To achieve these goals, this utility model employs following technical scheme：

A kind of PE pipe fittings, including interior PE layers are designed, the outside of the interior PE layers is arranged with successively from inside to outside the first steel pipe Layer, the second steel pipe layer, the outside of first steel pipe layer is arranged at intervals with multiple first raised lines along its length direction, and described the The inside of two steel pipe layers is arranged at intervals with multiple second raised lines, first steel pipe layer and the second steel pipe layer along its length direction It is connected by the first raised line, the second raised line respectively, the outside of second steel pipe layer is arranged with serpentine pipe, the serpentine pipe Outside be arranged with outer PE layers.

Preferably, first raised line is equal in the outside of the second steel pipe layer in the inside of the second steel pipe layer and the second raised line It is circumferentially equidistant from arrangement along its.

Preferably, the outside of the outer PE layers is provided with insulating moulding coating layer.

Preferably, the two ends of the interior PE layers are provided with screw thread.

The utility model proposes a kind of PE pipe fittings, beneficial effect is：Two-layer is set between interior PE layers and outer PE layers Steel pipe can increase the overall intensity of pipe fitting, and be connected and can be played by raised line between the first steel pipe layer and the second steel pipe layer Certain bracing reinforcement effect, is arranged on the serpentine pipe outside the second steel pipe layer and has the second weight bracing reinforcement effect, Er Qie Pipe fitting overall weight is also mitigated while reinforcing to pipe fitting intensity, and also saves cost of manufacture.This practicality is new Type has the advantages that simple structure, reasonable in design, easy to use, and to pipe fitting multiple bracing reinforcement has been carried out, and can be effectively increased pipe Part overall intensity, it is to avoid the problem that long-time use can deform or ftracture.

Fig. 2 be the utility model proposes a kind of PE pipe fittings spiral tube structure schematic diagram.

In figure：Interior PE layers 1, the first steel pipe layer 2, the second raised line 3, the second steel pipe layer 4, serpentine pipe 5, the first raised line 6, outer PE Layer 7.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.

With reference to Fig. 1-2, a kind of PE pipe fittings, including interior PE layers 1, the two ends of the interior PE layers 1 are provided with screw thread, be easy to and The pipeline at two ends is attached, and the outside of interior PE layers 1 is arranged with successively from inside to outside the first steel pipe layer 2, the second steel pipe layer 4, the The outside of one steel pipe layer 2 is arranged at intervals with multiple first raised lines 6 along its length direction, and the inside of the second steel pipe layer 4 is along it Length direction is arranged at intervals with multiple second raised lines 3, and the first raised line 6 and the second raised line 3 have certain adding to pipe fitting body Gu effect.

First steel pipe layer 2 and the second steel pipe layer 4 are connected respectively by the first raised line 6, the second raised line 3, the first raised line 6 It is circumferentially equidistant from arrangement each along its in the outside of the second steel pipe layer 4 in the inside of the second steel pipe layer 4 and the second raised line 3, just Connection between the first steel pipe layer 2 and the second steel pipe layer 4, the outside of the second steel pipe layer 4 is arranged with serpentine pipe 5, and serpentine pipe 5 has There is certain bracing reinforcement effect, and it also avoid increasing the overall weight of pipe fitting, the outside of serpentine pipe 5 while reinforcing Outer PE layers 7 are arranged with, the outside of outer PE layers 7 is provided with insulating moulding coating layer, it is to avoid temperature is too high to impacting inside PE pipes.

Two-layer steel pipe is arranged between interior PE layers 1 and outer PE layers 7 can increase the overall intensity of pipe fitting, and the first steel pipe layer 2 And second be connected between steel pipe layer 4 by raised line and can play certain bracing reinforcement effect, the second steel pipe layer 4 is arranged on Outside serpentine pipe 5 has the second weight bracing reinforcement effect, and pipe is also mitigated while reinforcing to pipe fitting intensity The overall weight of part, and also save cost of manufacture.

The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality New technical scheme and its utility model design in addition equivalent or change, all should cover in protection model of the present utility model Within enclosing.
