Abstract
The invention relates to a connecting method of polyethylene composite tubes of a steel wire gauze framework. The method comprises the following steps of: processing a turnup at 90 degrees at the end of a pipeline and adding a metal sleeve on the outer surface at the pipe end; buckling the two integrally; and connecting the turnup at 90 degrees and the metal sleeve by a metal hoop to enhance the strength of the turnup at 90 degrees. In addition, when the pipelines are connected, the metal hoop further has the effect of enhancing the strength of sealing gaskets among the pipe ends, so that the pressure bearing capacity in the connecting part is improved, and the pressure bearing capacity in the connecting part is greater than that of the tube product.
Description
Affiliated technical field
The present invention relates to engineering pipeline, be specially the connecting means of a kind of steel wire mesh frame polyethylene compound pipe, be used for the connection in fields such as steel wire mesh frame polyethylene compound pipe plumbing.
Background technique
At present, the connecting means of known steel wire mesh frame polyethylene compound pipe 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 the liquid conveying.
Summary of the invention
The objective of the invention is to overcome the prior art deficiency, a kind of connecting means of new steel wire mesh frame polyethylene compound pipe is provided, this method one is that connection is firm, pressure that the joint potential energy bears even the ultimate pressure that can be born 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 technical solution problem of the present invention is adopted is: a kind of connecting means of steel wire mesh frame polyethylene compound pipe, comprise the steps: to be inserted in prefabricated metal flange and metal sleeve in the tubing body end earlier, there is the abduction baffle ring that is connected as a single entity this metal sleeve end, with metal sleeve by withholding the equipment fastening on the tubing body, then the tubing body end is processed 90 ° of flangings, the flanging external diameter is consistent with the baffle ring external diameter, by the metal ferrules of withholding the inside flanging in an end at 90 ° of flanging cylindricals and baffle ring cylindrical, 90 ° of flangings and metal sleeve are connected together, placing the sealer packing ring in the space between the flanging, links together 2-section pipe material body by flange connection in tubing body end face and metal ferrules at last.
On the described metal sleeve inwall ripple pawl is arranged.
Described metal ferrules inwall is provided with pawl.
Described flange connection 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, 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 have strengthened the join strength between tubing and the metal sleeve, and metal ferrules has strengthened the intensity that connects sealer packing ring between the end face.After pipeline was connected by bolt and iron flange, the joint potential energy bore the pressure higher than tubing body, can guarantee the long-term safety operation of tubing.
Beneficial effect of the present invention: the one, it is firm to connect, and pressure that the joint potential energy bears even the ultimate pressure that can be born 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is that structural representation cuts open in Placement of the present invention office;
Fig. 2 is a tube end sectional structure schematic representation in the Placement of the present invention.
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-flanges.
Specifically execute real mode
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 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 with metal ferrules 5 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. 2,90 ° 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 90 ° of flangings in tubing body 1 end and metal sleeve 2 end faces.The space that forms between 90 ° of in-flangess 9 that metal ferrules 5 ends are inside and the tubing body end face is used to place sealer packing ring circle 6.
