Abstract
The connection pipe fitting of macromolecule material tubing includes the flange unit, is placed on the distolateral annular unit of the flange mouth of pipe and makes it compress connection structure connecting mutually.Wherein the flange nose end periphery that is used for matching with mouth of pipe inwall is the tapering shape, and is provided with the first anti-slip structure, is used in the annular unit matching with mouth of pipe outer wall merging the inner peripheral surface place with the tapering that adapts and being provided with the second anti-slip structure.This connection pipe fitting can adopt mechanical external pressure compact form to be engaged in macromolecule material tubing mouth end, can have the excellent performance of bearing axial tension.
Description
Technical field
The utility model relates to a kind of for comprising between the macromolecular material pipe of plastic tube or it is connected the connection pipe fitting of usefulness with metal tube.
Background technique
In many fields such as industrial, civilian, very extensive to the use of the macromolecule material pipe of all types of plastic pipe and other form.With all types of plastic tubing (or compound plastic pipe) is example, pressure-resistant plastic tubing is when interconnecting, to at present general hot melts butt joint or the electrothermal smelting tube modes such as (flanges) of adopting of its connector portions more, make the mutual fusion of outer wall plastics of the inwall plastics of pipe fitting and tubing end and link together.This Placement often is difficult to bear the tubing axial tension that causes because of distortion in construction and using process, thereby the pipeline connection part was lost efficacy.And the tubing of unlike material, the difficulty of construction when interconnecting as plastic tube and metal tube will be bigger, and will be also more difficult.
The model utility content
At above-mentioned situation, it is a kind of for comprising between all kinds of macromolecule material pipes of plastic tube or unlike material tubing such as itself and metal pipe interconnect the connection pipe fitting of usefulness that the utility model will provide.
The connection pipe fitting of macromolecule material tubing of the present utility model, based on flange modular construction commonly used, as include seal washer between flange (dish), flange and the clamping bolt between relative flange etc., be provided with in addition and be placed on the distolateral annular unit of the flange mouth of pipe and make it compress connection structure connecting mutually.Wherein, the periphery that this flange nose end is used for matching with mouth of pipe inwall is the tapering shape, and is provided with the first anti-slip structure; Be used in the annular unit matching and merge inner peripheral surface place and be provided with the second anti-slip structure with the tapering that adapts with mouth of pipe outer wall.
Above-mentioned connection pipe fitting is when construction, can earlier the annular unit be enclosed within the connecting end oral area of macromolecule tubing, after then the connecting end oral area of tubing being carried out the enlarging of appropriate amount, it is inserted in the nose end that flange is the tapering shape, with suitable linkage structures such as bolts the tube wall of pipe end is compressed mutually between this annular unit and flange nose end again, and guaranteed the tight reliability of its connection by the anti-slip structure between the relative side face of annular unit and flange nose end.Another tubing interconnective with it, no matter be the identical material or the tubing of unlike material, for example common plastics tube, band metal strengthen between the plastic tube of structure, or its with metal between being connected of pipe, only need the spout part of its connecting end to have the interconnective flange modular construction of energy, can easily it be interconnected, thereby can have extensive applicability.
Test shows that the mechanical external pressure compact form of this employing of the present utility model is engaged in macromolecule material tubing mouth end, connects reliable for effectly, can have the performance of bearing axial tension of excellence.
In above-mentioned connection pipe fitting, said this first anti-slip structure and/or the second anti-slip structure can be adopted as along the place side face generally speaking around simple forms such as the dentation structures that is provided with.
For further improving the sealability of above-mentioned said connection pipe fitting and macromolecule tubing connection part, on the basis of said structure, can also be provided with the corresponding cooperation annular groove that is used to put suitable seal ring in the increase of the outer circumferential face place of said flange nose end.
Below, foregoing of the present utility model is described in further detail again by embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
Description of drawings
Fig. 1 is a kind of structural representation of the connection pipe fitting of the utility model macromolecule material tubing.
Fig. 2 is the structure for amplifying schematic representation of the clamping sleeve of ring-type among Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the structure of the connection pipe fitting of this macromolecule material tubing, comprise by flange 1, connecting bolt 3 and seal washer 6 isostructural flange unit, at the distolateral clamping sleeve 2 that is equipped with a ring-type of the mouth of pipe of flange 1, it is with 1 of flange and be provided with and be used to make it to compress the bolt 4 that is connected mutually.The periphery that the nose end of flange 1 is used for matching with tubing 9 port inner walls is the tapering shape, and is provided with the cooperation annular groove that is used to put seal ring 5, also is provided with the first anti-skidding decylization toothing 8 on this outer circumferential face; Being used for port outer wall with tubing 9 in the annular cover 2 matches and merges the inner peripheral surface place with the tapering that adapts and also be provided with the second anti-skidding decylization toothing 7.
Shown among the figure, the plastic tube 9 that is two sections identical materials is through the interconnective state of above-mentioned connection pipe fitting.Wherein the tubing of these connection pipe fitting both sides also can be unlike material, and for example a side is for adopting the plastic tube of said structure form pipe fitting, and opposite side is the metal pipe with the interconnective conventional flange arrangement of energy.
