Description

A kind of plastics lined pipe
Technical field
Pipe-line equipment technical field is the utility model is related to, more specifically a kind of plastics lined pipe.
Background technology
Traditional running water pipe and other pipe fittings use metal tube mostly, the corrosion and metal tube gets rusty easily, therefore Progressively substituted by plastic pipe, but the problem of intensity is poor, easily deforms be present in plastic pipe, therefore people are increasingly Plastics lined pipe is used more.
Plastics lined pipe includes metal outer pipe and plastic inner pipe, and plastic inner pipe is adhered on metal outer pipe inwall.However, tradition lining It is not very firm that the plastic inner pipe of modeling pipe is connected with metal outer pipe, and under larger external force, plastic inner pipe is easily separated from outside metal Pipe, so that plastics lined pipe overall structure is destroyed.
Utility model content
In order to overcome above the deficiencies in the prior art, the utility model provides a kind of plastics lined pipe, its plastic inner pipe and metal Outer tube stable connection, avoid the situation that plastic inner pipe is easily separated from metal outer pipe.
To solve prior art problem, the technical solution adopted in the utility model is:
A kind of plastics lined pipe, including metal outer pipe and plastic inner pipe, the plastic inner pipe length are grown less than or equal to metal outer pipe Degree, and be installed on metal outer pipe inwall;The metal outer pipe both ends are arranged with adpting flange, and the adpting flange end face is fixed Limited bit architecture, the position limiting structure abut with plastic inner pipe end face.
Further, the metal outer pipe inwall is provided with plastics glue-line, and the plastic inner pipe is adhered to by plastics glue-line On metal outer pipe inwall.
Further, the plastic inner pipe is that PE is managed or EP is managed, and the thickness ratio of plastic inner pipe and metal outer pipe is 1:5.
Further, the position limiting structure includes the fixed block and limited block being connected with each other, and the fixed block is adhered to company Acting flange end face, the limited block are adhered on metal outer pipe inwall, and are abutted with plastic inner pipe end face;The thickness of limited block is big In both plastic inner pipe and plastics glue-line thickness sum.
Further, the adpting flange end face offers a plurality of annular groove, and the fixed block is relative with adpting flange A plurality of annular lug is installed with side, the annular lug is adapted with annular groove shape, and bonding is arranged on the annular In groove.
Further, annular groove is offered on the fixed block another side, sealing is installed in the annular groove Cushion rubber.
Further, worn between the fixed block and adpting flange and be connected to fixing bolt, the adpting flange is provided with and passed through Logical positioning hole, the positioning hole are located at fixing bolt periphery.
Compared with prior art, the utility model plastics lined pipe includes metal outer pipe and plastic inner pipe, and metal outer pipe both ends are set up separately There is adpting flange, adpting flange end face is installed with position limiting structure, and position limiting structure abuts with plastic inner pipe end face;Herein, due to Position limiting structure is connected to plastic inner pipe end face, and such plastic inner pipe is located between two position limiting structures at plastics lined pipe both ends, spacing knot Structure plays position-limiting action to plastic inner pipe, avoids plastic inner pipe from being subjected to displacement under external force, and then departs from metal outer pipe, protects It is more firm plastics lined pipe overall structure has been demonstrate,proved.

Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further:
As shown in figure 1, a kind of plastics lined pipe, including metal outer pipe 10 and plastic inner pipe 20, the length of plastic inner pipe 20 is less than etc. In the length of metal outer pipe 10, and it is installed on the inwall of metal outer pipe 10;The both ends of metal outer pipe 10 are arranged with adpting flange 11, connection The end face of flange 11 is installed with position limiting structure 40, and position limiting structure 40 abuts with the end face of plastic inner pipe 20.
The both ends of metal outer pipe 10 of the utility model plastics lined pipe are arranged with adpting flange 11, and the end face of adpting flange 11 is installed with Position limiting structure 40, position limiting structure 40 abut with the end face of plastic inner pipe 20;Herein, adpting flange 11 is used to connect different plastics lined pipes Pick up and;And because position limiting structure 40 is connected to the end face of plastic inner pipe 20, such plastic inner pipe 20 is located at the two of plastics lined pipe both ends Between position limiting structure 40, position limiting structure 40 plays position-limiting action to plastic inner pipe 20, avoids plastic inner pipe 20 under external force It is subjected to displacement, and then departs from metal outer pipe 10, ensure that plastics lined pipe overall structure is more firm.
In order to ensure that plastic inner pipe 20 can be arranged on the inwall of metal outer pipe 10, the inwall of metal outer pipe 10 is provided with plastic cement Layer 30, plastic inner pipe 20 is adhered on the inwall of metal outer pipe 10 by plastics glue-line 30.
Herein, plastic inner pipe 20 is that PE is managed or EP is managed, and in order to ensure that plastics lined pipe integrally has larger structural strength, The thickness ratio of plastic inner pipe 20 and metal outer pipe 10 is 1:5;So under external force, plastics lined pipe will not also become easily Shape.
Herein, position limiting structure 40 includes the fixed block 42 and limited block 41 being connected with each other, in order to ensure that position limiting structure 40 integral installations are fixed, and fixed block 42 is adhered to the end face of adpting flange 11, and limited block 41 is adhered on the inwall of metal outer pipe 10, and Abutted with the end face of plastic inner pipe 20;In addition, in order to ensure that limited block 41 plays good position-limiting action to plastic inner pipe 20 so that Plastic inner pipe 20 can not leave the inner chamber of metal outer pipe 10, and the thickness of limited block 41 is more than both plastic inner pipe 20 and plastics glue-line 30 Thickness sum, so, two limited blocks 41 clamp plastic inner pipe 20, it is not moved easily.
In order that fixed block 42 can be fixedly mounted on the end face of adpting flange 11, the end face of adpting flange 11 offers a plurality of ring Shape groove 14, a plurality of annular lug 43, annular lug 43 and annular are installed with the side relative with adpting flange 11 of fixed block 42 The shape of groove 14 is adapted, and is bonded and is arranged in annular groove 14;Herein, by setting a plurality of annular groove 14 and annular lug 43, the contact area of fixed block 42 and adpting flange 11 is significantly increased, so that fixed block 42 is more firmly mounted to The end face of adpting flange 11.In the present embodiment, three annular grooves 14 and annular lug 43 are provided with.
Herein, adpting flange 11 is used to connect different plastics lined pipes, in order to ensure the junction of different plastics lined pipes With good sealing property, annular groove 44 is offered on the another side of fixed block 42, sealing is installed in annular groove 44 Cushion rubber;Fixing bolt 13 is connected in addition, being worn between fixed block 42 and adpting flange 11, adpting flange 11 is provided with the positioning of insertion Hole 12, positioning hole 12 are located at the periphery of fixing bolt 13.So, will by positioning hole 12 when different plastics lined pipes are attached The position alignment of adpting flange 11 of different plastics lined pipes, while be fixedly connected with different plastics lined pipes by fixing bolt 13.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims Within the scope of.
