Abstract

The utility model discloses a 90-degree elbow joint. The 90-degree elbow joint comprises a hollow body; ports are respectively arranged at both ends of the hollow body; moreover, an annular bushing block and an annular sleeve copper component are coaxially connected to at least one port; each port is arranged on the sleeve copper component in a sleeving way; and the bushing block is arranged on each port in the sleeve way. The hollow body, the bushing block and the annular sleeve copper component are integrally arranged preferably. The 90-degree elbow joint disclosed by the utility model is simple and compact in structure, has the capacity of being firmly combined with pipeline systems of various types and leaks no liquid to the outside; and moreover, the 90-degree elbow joint is simple, convenient and quick in processing, high in production efficiency, low in production cost and applicable to various pipeline systems with buckling parts.

Description

90 ° of elbows

Technical field

The utility model relates to the joint mechanism of a kind of pipe-line system bending place, relates in particular to the structure improved 90 ° of elbows of a kind of tool.

Background technique

Generally all can have a large amount of bendings in all types of complex pipeline system that commonly sees, if directly pipeline is processed, and integrally formed bending, then not only manufacturing efficiency is low, and pipeline inconvenience deposits and transport, and is with high costs.So, people generally adopt and set up the joint with certain bent angle in pipe-line systems at present, in order to each road pipeline is connected to form pipe-line system, but existing pipe joint is usually by supports such as metal or engineering plastics, its inconvenient manufacturing, cost is high, and can't adapt to the firmness joint to the various material pipeline, and tends to cause pipe-line system the problems such as fluid leakage to occur.

The model utility content

The purpose of this utility model is to propose a kind of simple in structure, and is with low cost, is easy to 90 ° of elbows of large-scale production, to overcome deficiency of the prior art.

For realizing above-mentioned model utility purpose, the utility model has adopted following technological scheme:

A kind of 90 ° of elbows, comprise hollow body, described hollow body two ends are respectively equipped with a joining part, and wherein coaxial connection one ring bush and an annular cover copper spare at least one joining part, described joining part is set on the copper spare, and described lining is set on the joining part.

Preferably, described hollow body, lining and annular cover copper spare are integrated the structure of setting.

The annular end face of each joining part is all coated by lining.

Described lining preferably adopts stainless steel component, and described hollow body preferably adopts plastic parts.

Coaxially on the described cover copper spare outer wall be distributed with an above O type groove, in the described O type groove O type ring be installed.

Preferably, be distributed with worm structure on the described cover copper spare inwall.

The assembling procedure of these 90 ° of elbows is as follows: O type ring 3 is installed in the O type annular groove 5 that overlaps on the copper 2, and inserts in the mould with stainless steel lining 4, insert when injection molding and penetrate stroke in the mould.

Compared with prior art, the utility model has following advantage at least: this joint structure is simply fastening, with the equal energy of various types of pipe-line systems strong bonded, the anxiety that leaks without fluid, and its processing procedure is simple and efficient, manufacturing efficiency is high, and cost of production is low, is suitable for being applied in all kinds of pipe-line systems with kink.

Description of drawings

Fig. 1 is the stereogram of the utility model one preferred embodiment;

Fig. 2 is the cross-sectional view of the utility model one preferred embodiment shown in Figure 1;

Fig. 3 is the decomposition texture schematic representation of the utility model one preferred embodiment shown in Figure 2;

Each assembly and reference character thereof are respectively among the figure: comprise: body 1, cover copper spare 2, O type ring 3, stainless steel lining 4, O type annular groove 5.

Embodiment

Below in conjunction with accompanying drawing and a preferred embodiment content of the present utility model is further described.

Consult Fig. 1-3, these 90 ° of elbows comprise body 1, cover copper spare 2 and the stainless steel lining 4 of plastic cement material.Wherein, these hollow body two ends are respectively equipped with a joining part, and wherein coaxial connection one ring bush and an annular cover copper spare at least one joining part, and this joining part is set on the copper spare, and this lining is set on the joining part.Preferred distribution has the internal thread that cooperates with outside thread on the pipeline outer wall to be accessed on these cover copper spare 2 inwalls, simultaneously, also is distributed with vertically some O type annular grooves 5 on these cover copper spare 2 outer walls, is used for packing into O type seal ring 3, with the lift-off seal performance.

The assembling procedure of these 90 ° of elbows is as follows: O type ring 3 is installed in the O type annular groove 5 that overlaps on the copper spare 2, and inserts in the mould with stainless steel lining 4, insert when injection molding and penetrate stroke in the mould.

These 90 ° of elbow preparation procesies are simple and efficient, easy to implement, manufacturing efficiency exceeds the manufacture method of existing various elbows far away, and cost of production significantly reduces, simultaneously, these 90 ° of elbow structures are more simple firmly, with various types of pipe-line systems all can fastening combination, the anxiety that leaks without fluid.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
