Abstract

The application discloses heavy-calibre polyolefin pipe fitting, including two straight tubes and an return bend, two the straight tube concatenation sets up at the both ends of return bend, two the outer wall of straight tube and return bend is moulded plastics jointly and is had the fusion wall. This pipe fitting moulds plastics the plastic layer again on the body after the concatenation to reduce the single volume of moulding plastics, the production of being convenient for reduces the equipment requirement, and the plastic layer of parcel reduces the risk that the weld splits simultaneously, improves the pipe fitting quality.

Description

Large-diameter polyolefin pipe fitting
Technical Field
The application relates to the field of pipe fittings, in particular to a large-caliber polyolefin pipe fitting.
Background
At present, plastic pipe fittings become the leading force in the field of building drainage pipelines, and particularly the popularization and application of PE materials. Its advantages are light weight, high anticorrosion nature and convenient construction. The traditional cast iron pipe fittings are basically eliminated. The pipeline can not be installed away from the pipe fittings, and the most common pipe fittings comprise elbows, tee joints and the like.
In the prior art, a pipe fitting is generally integrally formed by injection molding, and in the production process of a large-caliber pipe fitting, the required injection molding capacity requirement is high due to the large mass of the pipe fitting, so that the production requirement cannot be met; and the large-caliber pipe is easy to crack in the using process.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a heavy-calibre polyolefin pipe fitting to overcome not enough among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme:
the embodiment of the application discloses heavy-calibre polyolefin pipe fitting which characterized in that: the fusion welding device comprises two straight pipes and an elbow, wherein the straight pipes are spliced at two ends of the elbow, and fusion walls are jointly molded on the outer walls of the straight pipes and the elbow.
Preferably, in the above-mentioned one large-caliber polyolefin pipe, the thickness of the fused wall is the same as that of the straight pipe.
Preferably, in the above-mentioned polyolefin pipe with a large diameter, the wall thickness of the bent pipe is the same as that of the straight pipe.
Preferably, in one of the above-mentioned polyolefin pipes with large caliber, the fusion wall is PE.
Compared with the prior art, the utility model has the advantages of:
this pipe fitting moulds plastics the plastic layer again on the body after the concatenation to reduce the single volume of moulding plastics, the production of being convenient for reduces the equipment requirement, and the plastic layer of parcel reduces the risk that the weld splits simultaneously, improves the pipe fitting quality.
Drawings
In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present application, and it is obvious for those skilled in the art to obtain other drawings based on the drawings without creative efforts.
Fig. 1 is a schematic structural diagram of a large-diameter polyolefin pipe according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the large-caliber polyolefin pipe fitting in this embodiment includes two straight pipes 1 and an elbow pipe 2, the two straight pipes 1 are spliced at two ends of the elbow pipe 2, and the outer walls of the two straight pipes 1 and the elbow pipe 2 are jointly molded with a fusion wall 3.
Further, the thickness of the fusion wall 3 is the same as that of the straight pipe.
Further, the wall thickness of the bent pipe 2 is the same as that of the straight pipe 1.
Further, the fusion wall 3 is PE.
In this technical scheme, the plastic layer of moulding plastics again on the body of this pipe fitting after the concatenation to reduce the single volume of moulding plastics, the production of being convenient for reduces the equipment requirement, and the plastic layer of parcel reduces the risk that the weld splits simultaneously, improves the pipe fitting quality.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The foregoing is merely a detailed description of the present application, and it should be noted that modifications and embellishments could be made by those skilled in the art without departing from the principle of the present application, and these should also be considered as the protection scope of the present application.
