Abstract

The invention discloses a tee joint, which comprises a hollow body (1), wherein at least three connector parts are arranged on the hollow body; a bush (4) is sleeved on each connector part coaxially; an annular sleeve copper piece (2) is coaxially arranged in each connector part; and an outer wall of the annular sleeve copper piece (2) is fit with an inner wall of the hollow body (1). Preferably, an annular end face of each connector part is covered by the bush (4). More than one O-shaped slot (5) is coaxially distributed on the outer wall of the annular sleeve copper piece (2); and an O-shaped ring (3) is arranged in each O-shaped slot. The tee joint has a simple and compact structure, can be firmly combined with various pipeline systems, has no trouble of fluid leakage, is easy to prepare, has low cost, and is applied to various complex pipeline systems.

Description

Tee union

Technical field

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

Background technique

In the complex fluid pipe-line system, generally can have a large amount of branch roads, 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 firmness joint, and tend to cause pipe-line system problems such as fluid leakage to occur the various material pipeline.

Summary of the invention

The objective of the invention is to propose a kind of simple in structure, with low cost, be easy to the tee union of large-scale production, to overcome deficiency of the prior art.

For realizing the foregoing invention purpose, the present invention has adopted following technological scheme:

A kind of tee union is characterized in that it comprises hollow body; Said hollow body is provided with at least three joining part; And a coaxial sheathed lining on each joining part, and the also coaxial annular cover copper spare that is provided with in each joining part, said annular cover copper spare outer wall and hollow body inwall are fitted.

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

Said lining preferably adopts stainless steel component.

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

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

Particularly preferred, said hollow body, lining and annular cover copper spare are the structure that is wholely set.

The assembling procedure of this tee union is following: O type ring is installed in the O type annular groove of cover on the copper spare, and again in lining is inserted mould, when injection molding, inserts and penetrate stroke in the mould.

Compared with prior art, the present invention has following advantage at least: this joint structure is simply fastening, with the equal ability of various types of pipe-line systems strong bonded, the anxiety that no fluid leaks, and is easy to preparation, and 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 present invention's one preferred embodiment;

Fig. 2 is the cross-sectional view of the present invention's one preferred embodiment shown in Figure 1;

Fig. 3 is the decomposition texture schematic representation of the present invention's 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 an accompanying drawing and a preferred embodiment content of the present invention 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 also coaxial annular cover copper spare that is provided with in each joining part, this annular cover copper spare outer wall and hollow body inwall are fitted.

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

The assembling procedure of this tee union is following: O type ring 3 is installed in the O type annular groove 5 on the cover copper spare 2, and inserts in the mould with stainless steel lining 4, when injection molding, insert 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 fastening combination of equal ability, the anxiety that no fluid leaks.

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