Abstract

The utility model discloses a tee joint. The tee joint comprises a hollow body (1); at least three interface parts are arranged on the hollow body; a liner bushing (4) is coaxially sheathed on each interface part; an annular bushing copper piece (2) is also coaxially arranged in each interface part; and the outer wall of the annular bushing copper piece (2) is glued to the inner wall of the hollow body (1). Preferably, the annular end surface of each interface part is coated by the liner bushing (4). Moreover, more than one O-shaped groove (5) is coaxially distributed on the outer wall of the annular bushing copper piece (2); and each O-shaped groove is internally provided with an O-shaped ring (3). The tee joint has the advantages of being simple and firm in structure, capable of firmly combining with various pipelines without fluid leakage, easy to manufacture, low in cost and suitable for being applied in various complex pipeline systems.

Description

Tee union

Technical field

The utility model relates to a kind of joint mechanism of pipe-line system, relates in particular to the structure improved tee union of a kind of tool.

Background technique

Generally can have a large amount of branch roads in the complex fluid pipe-line system, for reaching purposes such as simplifying pipeline structure, people can set up tee union etc. usually in pipe-line system.But existing tee union forms by metal or engineering plastics etc. are whole usually, itself or with high costs, or a little less than the bearing capacity, can't adapt to the firmness joint to the various material pipeline, and tend 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 the tee union 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 tee union is characterized in that it comprises hollow body, described hollow body is provided with at least three joining part, and a coaxial sheathed lining on each joining part, and the interior also coaxial annular cover copper spare that arranges of each joining part, described annular is overlapped copper spare outer wall and the applying of hollow body inwall.

Preferably, all coated by lining on the annular end face of each joining part.

Described lining preferably adopts stainless steel component.

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.

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

The assembling procedure of this tee union is as follows: O type ring is installed in the O type annular groove of cover on the copper spare, and again in lining is inserted mould, inserts 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 various types of pipe-line systems all can strong bonded, the anxiety that leaks without fluid, and be easy to preparation, cost is low, is suitable for being applied in all kinds of complicated pipe-line systems.

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 diagram 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, this tee union comprises hollow body 1, cover copper spare 2 and the stainless steel lining 4 of plastic cement material, this hollow body is provided with three joining part, a coaxial sheathed lining on each joining part, and the interior also coaxial annular cover copper spare that arranges of each joining part, this annular cover copper spare outer wall and hollow body inwall are fitted.

Preferred distribution has the internal thread that cooperates with outside thread on the pipeline outer wall to be accessed on these cover copper 2 inwalls, simultaneously, also is distributed with vertically some O type annular grooves 5 on these cover copper 2 outer walls, is used for packing into O type seal ring, with the lift-off seal performance.

The assembling procedure of this tee union 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.

Preparation process is simple and efficient for this tee union, easy to implement, manufacturing efficiency exceeds the manufacturing process of existing various tee unions far away, and cost of production significantly reduces, simultaneously, this tee union structure is 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.
