Abstract
The utility model relates to engineering pipelines, in particular to a connecting structure of a steel wire gauze framework polyethylene composite pipe. The connecting structure comprises a pipe body, a metal flange plate and a metal casing pipe, wherein an outward-expanding check ring is arranged at the end portion of the metal casing pipe and is connected with the metal casing pipe into a whole, a 90-degree outward-overturning edge is machined at the end portion of the pipe body, the outer diameter of the 90-degree outward-overturning edge is coincident with the outer diameter of the check ring, a ferrule connects the 90-degree outward-overturning edge with the metal casing pipe, one end of the ferrule is bent inwards, and a sealing rubber ring is arranged in the space between the end face of the pipe body and the inward-folding edge of the ferrule. The connecting structure has the advantages that connection is firm, the pressure borne by the connecting portion is even larger than the limiting pressure borne by the pipe body, and long-term safe operation of the pipe can be ensured; the connecting structure is economical and feasible, accessories are easy to manufacture, and assembling is easy.
Description
Affiliated technical field
The utility model relates to engineering pipeline, is specially a kind of steel wire mesh frame polyethylene compound pipe linkage structure, and the pipeline that is used for fields such as steel wire mesh frame polyethylene compound pipe plumbing connects.
Background technique
At present, known steel wire mesh frame polyethylene compound pipe linkage structure is that electrothermal smelting tube connects and metal button pressure pipe part connects.The problem that exists is, it is poor that condenser type connects high voltage performance, and metal button pressure pipe part connects to exist for large diameter pipeline withholds that equipment investment is huge, to withhold the mould cost too high, connects to have boss in the pipeline of back and influence problem such as liquid conveying.
The model utility content
The purpose of this utility model is to overcome the prior art deficiency, a kind of linkage structure of new steel wire mesh frame polyethylene compound pipe is provided, the one, it is firm to connect, and the pressure that the joint potential energy bears even the ultimate pressure that can bear greater than the tubing body can be guaranteed the long-term safety operation of pipeline; The 2nd, economically feasible comparatively, accessory is easily made, and assembling is easier to.
The technological scheme that the utility model technical solution problem adopts is: a kind of linkage structure of steel wire mesh frame polyethylene compound pipe, comprise tubing body, metal flange dish, metal sleeve, there is the abduction baffle ring that is connected as a single entity described metal sleeve end, the tubing body end has the 90 ° of flangings that of processing, 90 ° of flanging external diameters are consistent with the baffle ring external diameter, the metal ferrules of the inside flanging of an end that 90 ° of flangings of handlebar and metal sleeve connect together, in the space in tubing body end face and metal ferrules between the flanging, the sealer packing ring is arranged.
On the described metal sleeve inwall ripple pawl is arranged.
Described metal ferrules inwall is provided with pawl.
Described metal flange dish Placement is that bolt connects.
The external diameter of described sealer packing ring is identical with the interior circular diameter of flanging in the metal ferrules.
Because the external diameter of the sealer packing ring between the pipe end is identical with the metal ferrules minimum diameter, after pipeline connects by bolt and iron flange dish, the sealing rubber gasket is pressed on two pipe end faces and metal ferrules is limit within the space, the effect of flanging in the metal ferrules can prevent that the sealer packing ring from outwards running out of under high pressure conditions.
90 ° of flangings of tube end cooperate the join strength that has strengthened between tubing and the metal sleeve with metal ferrules, metal ferrules has also strengthened the intensity that connects sealer packing ring between the end face.After pipeline was connected by bolt and metal flange dish, the joint potential energy bore the pressure higher than tubing body, can guarantee the long-term safety operation of tubing.
The beneficial effects of the utility model: the one, it is firm to connect, and the pressure that the joint potential energy bears even the ultimate pressure that can bear greater than the tubing body can be guaranteed the long-term safety operation of tubing; The 2nd, economically feasible comparatively, accessory is easily made, and assembling is easier to.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that structural representation cuts open in the utility model Placement office;
Fig. 2 is tube end sectional structure schematic representation in the utility model Placement.
Among the figure, 1. tubing body, 2. metal sleeve, 3. flange plate, 4. bolt, 5. metal ferrules, 6. sealer packing ring, 7. nut, 8. pawl, 9. in flanging.
Embodiment
Embodiment: in Fig. 1, earlier flange plate 3 is enclosed within on the tubing body 1, tubing body 1 is connected as a single entity by the 90 ° of flangings in end and metal sleeve 2, and metal sleeve 2 is after withholding processing, and the pawl 8 of its internal surface is pressed into tubing body 1 inside.On the metal sleeve 2 end cylindricals groove is arranged.Utilize external force metal ferrules 5 is terminal in the pawls of circle be pressed in the groove on metal sleeve 2 cylindricals, 90 ° of flangings of tubing body 1 end and metal sleeve 2 are close together.The external diameter of sealer packing ring 6 is slightly less than the internal diameter of metal ferrules 5 end faces.During connection, earlier sealer packing ring 6 is placed between the internal diameter of two tubing body 1 end faces and metal ferrules 5 end faces, is tightened to one with bolt 4 and nut 7 again.
In Fig. 2, the 90 ° of flangings in tubing body 1 end and metal sleeve 2 end faces stick together, and metal sleeve 2 rear portions are through withholding processing, and the tooth of its internal surface is pressed into tubing body 1 inside.Metal ferrules 5 connects as one the 90 ° of flangings in tubing body 1 end and metal sleeve 2 end faces.The space that forms between 90 ° of flangings that metal ferrules 5 ends are inside and the tubing body end face is used for placing sealer packing ring 6.
Claims (5)
1. the linkage structure of a steel wire mesh frame polyethylene compound pipe, comprise tubing body, metal flange dish, metal sleeve, it is characterized in that there is the abduction baffle ring that is connected as a single entity described metal sleeve end, the tubing body end has the 90 ° of flangings that of processing, 90 ° of flanging external diameters are consistent with the baffle ring external diameter, the metal ferrules of the inside flanging of an end that 90 ° of flangings of handlebar and metal sleeve connect together in the space in tubing body end face and metal ferrules between the flanging, has the sealer packing ring.
