Abstract
The utility model is a kind of steel wire polyethylene compound pipe fast joint structure part, there is the metal sleeve withheld on pipe shaft oral area periphery, pipe shaft two ends, metal sleeve port has the flange back-up ring of radial abduction, flange back-up ring end face indent, interior recess has 90 ° of flangings of body, annular groove is formed between flanging edge and flange back-up ring, the O-ring seal matched is had in groove, have kink steel flange inside metal sleeve outward flange back-up ring, steel flange internal diameter is greater than the outer warp of metal sleeve and is less than metal sleeve outward flange back-up ring external diameter.Effect is: tubing connection part intensity is high, avoids the corrosive action of managing interior acid-base medium, guarantees the long-term safety of tubing.
Description
Art
The utility model relates to the connection in polyethylene compound pipe road, is specially a kind of steel wire polyethylene compound pipe fast joint structure part.
Background technique
At present, the connecting means of known steel-wire carcass polyethylene compound pipe is that electrothermal smelting tube connects and withholds pipe fitting connection, is generally not suitable for field and connects fast.
Model utility content
The purpose of this utility model is to provide the quick connector element of a kind of steel wire mesh frame polyethylene compound pipe, by arranging the flange alive of metalloid pipeline at body end portion, connects with bolt, simple and quick, and good seal compressive strength is high.
The technological scheme that the utility model technical solution problem adopts is: a kind of steel wire polyethylene compound pipe fast joint structure part, the pipe shaft related to comprises inner plastic, steel wire mesh frame layer, outer plastic layer, there is the metal sleeve withheld on pipe shaft oral area periphery, pipe shaft two ends, metal sleeve port has the flange back-up ring of radial abduction, flange back-up ring end face indent, interior recess has 90 ° of flangings of body, annular groove is formed between flanging edge and flange back-up ring, the O-ring seal matched is had in groove, kink steel flange is had inside metal sleeve outward flange back-up ring, steel flange internal diameter is greater than the outer warp of metal sleeve and is less than metal sleeve outward flange back-up ring external diameter, described steel flange has connecting bolt supporting with it.
Described connecting bolt is self-fastening bolt.
The cross-sectional configuration of seal rubber pad used is "T"-shaped.
The course of working of tube connection piece: first above-mentioned iron flange and metal sleeve are enclosed within pipe end, tubing exposes metal sleeve one segment length, utilizes press machine to be pressed on tubing cylindrical by metal sleeve.Then, will expose the pipe end heating of metal sleeve, afterwards, utilize mould, tube end maching is gone out 90 ° of flange, the end face of 90 ° of flange and metal sleeve fits together.Meanwhile, outside the end face of 90 ° of flange and between metal sleeve cylindrical, process and within one week, place the groove that cross section is "T"-shaped seal rubber pad.The physical dimension of "T"-shaped seal rubber pad coordinates with the physical dimension of 90 ° of flange, and its outward edge is just placed in the groove outside 90 ° of flange end faces and between metal sleeve cylindrical.
It is advantageous that, by processing 90 ° of flange of pipe end, the steel wire in tube wall is made to create the corner of 90 ° in the corner, inner side of metal sleeve end face, join strength between steel wire and metal sleeve improves greatly, after two tubing connect, steel wire in flange end face, by two metal sleeves pressing together tightly, adds the reinforing function of metal sleeve butt joint position tubing, makes the intensity of joint area much larger than the intensity of tubing body.
The beneficial effects of the utility model are, tubing connection part intensity is high, even much larger than tubing bulk strength.Meanwhile, steel wire is closed by pipe material inner wall plastics and seal rubber pad, can not cause medium " string water " phenomenon along steel wire to tube wall internal penetration.Avoid the corrosive action of managing interior acid-base medium, can not impact the steel wire of tube wall inside, guarantee the long-term safety of tubing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is that structure enlarged diagram is partly cutd open in local of the present utility model;
Fig. 2 is the structural representation of supporting T-shape cross section cushion rubber.
In figure, 1. pipe shaft, 2. metal sleeve, 3. flange plate, 4. 90 ° of flange of body end, 5. place the groove of seal rubber pad, 6. flange back-up ring.
Specifically execute real mode
A kind of steel wire polyethylene compound pipe fast joint structure part, the pipe shaft related to comprises inner plastic, steel wire mesh frame layer, outer plastic layer, there is the metal sleeve 2 withheld on pipe shaft oral area periphery, pipe shaft 1 two ends, metal sleeve port has the flange back-up ring of radial abduction, flange back-up ring 6 end face indent, interior recess has 90 ° of flangings of body, annular groove 5 is formed between flanging edge and flange back-up ring, the O-ring seal matched is had in groove 5, kink steel flange is had inside metal sleeve outward flange back-up ring, steel flange internal diameter is greater than the outer warp of metal sleeve and is less than metal sleeve outward flange back-up ring 6 external diameter.Described steel flange has connecting bolt supporting with it, and bolt adopts plain bolt or self-fastening to connect bolt soon can.
First flange plate 3 is enclosed within tubing body 1, afterwards metal sleeve 2 is placed into tubing body 1 end, and make tubing body 1 pipe end expose metal sleeve 2 certain length.By crimping equipment, metal sleeve 2 and tubing body 1 are pressed together.Then, the part tubing body 1 exposing metal sleeve 2 is heated to uniform temperature, then by mould and press machine, processes 90 ° of flange 4 of pipe end in the end of tubing body 1 and place the groove 5 of seal rubber pad.When connecting tubing, the T-shape cross section rubber cushion supporting with tubing being placed into and placing in the groove 5 of seal rubber pad, then with bolt, two tubing being fastened as a whole.
In Fig. 2, show the structure of the T-shape cross section rubber cushion supporting with tubing body 1.Its outward edge protrudes certain size to both sides vertically.
