Abstract
The invention discloses a metal insert used for an embedded type plastic pipe and provided with a sealing ring. The metal insert comprises a metal insert body, the surface of the metal insert body is provided with a sealing groove, and the sealing ring is installed in the sealing groove. Due to the fact that the sealing groove internally provided with the sealing ring is formed in the surface of the metal insert body, when connection between the metal insert and the plastic pipe loosens, the sealing ring will deform correspondingly and fill the looseness space, and then leakage can be avoided. The metal insert is applicable to embedded type plastic pipes.
Description
Technical field
The present invention relates to a kind of metal insert for embedded plastic pipe, particularly relate to a kind of embedded plastic pipe metal insert with seal ring.
Background technique
Embedded plastic pipe (plastic pipe of full name embedded metal part) manufacturing technology is that a kind of Shooting Technique that adopts is embedded in the plastic pipe production method in plastic pipe by metal insert, because it can reduce cost of material significantly, so embedded plastic pipe is applied widely.
At present, embedded plastic pipe generally comprises the plastic pipe body and is embedded in the intrinsic metal insert of plastic pipe.For preventing that metal insert from rotating with respect to the plastic pipe body, mostly can double wedge along the circumferential direction be set on the metal insert surface, but often there will be following problem in actual use:
Double wedge can only play the effect that prevents that metal insert from rotating with respect to the plastic pipe body to a certain extent, be subject to larger external force or fluid temperature variations when larger at embedded plastic pipe, the binding site of metal insert and plastic pipe body easily occurs loosening, thereby seepage occurs.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned background technology, provide a kind of simple in structure and can effectively prevent the embedded plastic pipe metal insert with seal ring of seepage.
In order to realize above purpose, a kind of embedded plastic pipe metal insert with seal ring provided by the invention, comprise the metal insert body, and described metal insert body surface is provided with sealed groove, in described sealed groove, seal ring is installed.By add the sealed groove of built-in seal ring at described metal insert body surface, like this, when occurring to become flexible between metal insert and plastic pipe body, described seal ring can deform thereupon and fill loosening space, thereby has avoided the generation of seepage.
In such scheme, described metal insert body surface along the circumferential direction is provided with dovetail groove, and this dovetail groove can prevent that metal insert from deviating from the plastic pipe body effectively.
In such scheme, the dovetail angle [alpha] of described dovetail groove is 45～85 °.
In such scheme, the dovetail groove width D >=5.7mm of described dovetail groove.
In such scheme, the end face of described metal insert body built-in end along the circumferential direction is provided with annular groove.During injection moulding, plastics can be filled completely described annular groove, and the plastics that are filled in described annular groove are equivalent to a seal ring, thereby have avoided further the generation of seepage.
In such scheme, described metal insert body surface along the circumferential direction at least is provided with two circle anti-rotation boss, and this anti-rotation boss can prevent from relatively rotating between described metal insert and plastic pipe body effectively.
In such scheme, the described anti-rotation boss of every circle at least comprises three anti-rotation boss, and described anti-rotation boss is evenly arranged along the circumferencial direction of described metal insert body surface.
In such scheme, described dovetail groove is arranged between described two circle anti-rotation boss.
In such scheme, described sealed groove is arranged between described dovetail groove and annular groove.
In such scheme, described seal ring is the fluorine rubber material.Certainly, also can adopt other heatproof flexible barrier materials.
One aspect of the present invention, by add the sealed groove of built-in seal ring at described metal insert body surface, like this, when occurring to become flexible between metal insert and plastic pipe body, described seal ring can deform thereupon and fill loosening space, thereby has avoided the generation of seepage; On the other hand, the dovetail groove added at described metal insert body surface can prevent that metal insert from deviating from the plastic pipe body effectively; Finally, the annular groove added at the end face of described metal insert body built-in end has been avoided the generation of seepage further.
The present invention is compared with the prior art, and fully show that its superiority is: simple in structure, leakage proof is effective etc.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The structural representation of looking up that Fig. 2 is Fig. 1;
Fig. 3 is the structural representation after molding and forming of the present invention.
In figure: metal insert body 1, sealed groove 2, seal ring 3, dovetail groove 4, annular groove 5, anti-rotation boss 6, plastic pipe body 7.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed as limitation of the present invention.
As shown in Figure 1: the present embodiment provides a kind of embedded plastic pipe metal insert with seal ring, comprises metal insert body 1, and described metal insert body 1 surface is provided with sealed groove 2, in described sealed groove 2, seal ring 3 is installed.By add the sealed groove 2 of built-in seal ring 3 on described metal insert body 1 surface, like this, when occurring to become flexible between metal insert 1 and plastic pipe body 7, described seal ring 3 can deform thereupon and fill loosening space, thereby has avoided the generation of seepage.During concrete production, also can design the sealed groove 2 of the built-in seal ring 3 of multi-turn.Certainly, also can adopt the sealing configuration of other structures.Described seal ring 3 is the fluorine rubber material.Certainly, also can adopt other heatproof flexible barrier materials.
Above-mentioned metal insert body 1 surface along the circumferential direction is provided with dovetail groove 4, during injection moulding, plastics can be filled completely described dovetail groove 4, the plastics and the described dovetail grooves 4 that are filled in described dovetail groove 4 form radially interface arrangment, can effectively prevent that metal insert 1 from deviating from plastic pipe body 7.During concrete production, also can design multi-turn dovetail groove 4.Certainly, also can adopt the radially interface arrangment of other structures.The dovetail angle [alpha] of described dovetail groove 4 is 45～85 °.The dovetail groove width D >=5.7mm of described dovetail groove 4.
The end face of above-mentioned metal insert body 1 built-in end along the circumferential direction is provided with annular groove 5.During injection moulding, plastics can be filled completely described annular groove 5, and the plastics that are filled in described annular groove 5 are equivalent to a seal ring, thereby have avoided further the generation of seepage.The socket end of described metal insert body 1 is provided with screw thread.
Above-mentioned metal insert body 1 surface along the circumferential direction at least is provided with two circle anti-rotation boss 6, and this anti-rotation boss 6 can prevent from relatively rotating between described metal insert 1 and plastic pipe body 7 effectively.Certainly, for cost-saving, also can only design a circle anti-rotation boss 6.The described anti-rotation boss 6 of every circle at least comprises three anti-rotation boss 6, and described anti-rotation boss 6 is evenly arranged along the circumferencial direction on described metal insert body 1 surface.Described anti-rotation boss 6 is trapezium structure, and the rotatory force that described like this anti-rotation boss 6 can bear is larger.
