Abstract
The invention discloses a direct head improved structure which comprises a straight pipe type body, wherein at least one end of the straight pipe type body is provided with an interface part, and the interface part is coaxially connected with an annular lining and an annular sleeve copper piece; the interface part is sleeved on the sleeve copper piece, and the lining sleeve is arranged on the interface part; and preferably, the straight pipe type body, the lining and the annular sleeve copper piece are arranged in an integrate manner. The direct head improved structure provided by the invention has the advantages that the structure is simple and firm, the direct head improved structure can be firmly combined with pipeline systems of different types, the fluid is not discharged, the manufacturing process is simple, convenient and rapid, the production efficiency is high, the manufacturing cost is low, and the direct head improved structure is especially applicable to a pipeline system formed by a metal pipeline and a plastic pipeline through connecting.
Description
Technical field
The present invention relates to a kind of joint mechanism of pipe-line system, relate in particular to the structure improved straight joint of a kind of tool.
Background technique
In all types of complex pipeline system that commonly sees, pipe joint is usually by supports such as metal or engineering plastics, its inconvenient manufacturing, and cost is high, and 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.
Summary of the invention
The object of the invention is to propose a kind of simple in structure, with low cost, be easy to the straight joint structure-improved of large-scale production, to overcome deficiency of the prior art.
For achieving the above object, the present invention has adopted following technological scheme:
A kind of straight joint structure-improved, it comprises a straight pipe type body, and at least one end of described straight pipe type body is provided with a joining part, a coaxial sheathed ring bush on the described joining part, and described joining part coaxial sleeve is located on the annular cover copper spare.
Preferably, described straight pipe type 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 straight pipe type 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 structure improved assembling procedure of this straight joint is as follows: O type ring is installed in the O type annular groove that overlaps on the copper, and inserts in the mould with the stainless steel lining, insert when injection molding 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 energy of various types of pipe-line systems strong bonded, the anxiety that leaks without fluid, and its processing procedure is simple and efficient, and manufacturing efficiency is high, and cost of production is low, be suitable for being applied in the various pipes system, in the pipe-line system that particularly is connected to form by metallic conduit and plastic pipe.
Description of drawings
Fig. 1 is the stereogram of a preferred embodiment of the present invention;
Fig. 2 is the cross-sectional view of a preferred embodiment of the present invention shown in Figure 1;
Fig. 3 is the decomposition texture schematic diagram of a preferred embodiment of the present invention shown in Figure 2;
Each assembly and reference character thereof are respectively among the figure: 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 invention is further described.
Consult Fig. 1-3, this straight joint structure-improved comprises straight pipe type body 1, cover copper spare 2 and the stainless steel lining 4 of plastic cement material.Wherein, at least one end of this straight pipe type body is provided with a joining part, coaxial connection one ring bush and an annular cover copper spare on this 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 structure improved assembling procedure of this straight joint 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 straight joint structure-improved, easy to implement, manufacturing efficiency exceeds the manufacture method of existing various straight joints far away, and cost of production significantly reduces, simultaneously, this straight joint structure-improved 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 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.
