Description
Technical field
It the utility model is related to a kind of pipeline rehabilitation equipment, and in particular to a kind of outer fixed ring type HDPE Flanges connection
Device.
Background technology
Pipeline HDPE no-dig technique insertion lining recovery techniques have been widely used at home, after liner process terminates
The artificial flange of generally use adds rubber seal connecting pipe, and this technology is only used for below 1.6MPa pressure pipeline, and
Because HDPE materials have dilatancy, sealing gasket installation specification is high, and the more difficult assurance of workmen is close during long-term use
Also easily there is leakage problem in packing, therefore pipeline connection technology limitation pressure piping can not use HDPE inner lining repairing techniques.
The content of the invention
The purpose of this utility model is that providing a kind of outer fixed ring type HDPE for problems of the prior art turns over
Side flange connecting apparatus, the attachment means can be used for the pressure pipeline no more than 10MPa, meet that most of pressure pipings repair need
Will, promoted for HDPE recovery techniques and play power-assisted effect.
The technical solution of the utility model is：
A kind of outer fixed ring type HDPE Flange attachment means, including, nonstandard flat flange, stainless steel retainer ring,
HDPE Flanges, fluted on the nonstandard flat flange, the stainless steel retainer ring is arranged on the outer of HDPE Flanges
Side is simultaneously fixed in the groove of nonstandard flat flange, sets bolt to be clamped using its screwing force on the outside of the nonstandard flat flange
HDPE Flanges.
Specifically, the HDPE Flanges have two, and two HDPE Flanges faces directly contact.
Specifically, the nonstandard flat flange fovea superior groove depth is 3mm-5mm.
Specifically, gap is less than 1mm between DHPE Flanges and stainless steel retainer ring.
The beneficial effects of the utility model are：The attachment means assembling structure is simple, and processing cost is low；It is simple to operate, can
It is strong, easy to maintenance by property.The nonstandard flat flange used in the utility model processes a groove on conventional panel flange, tool
Body position is on flange sealing surface, and near the inner side of bolt hole, effect is fixed stainless steel retainer ring, and depth of groove exists
3mm-5mm, stainless steel retainer ring is arranged on the outside of HDPE Flanges during assembling, and in the groove of steel flanges,
Gap should be less than 1mm between DHPE Flanges and retainer ring, and stainless steel, which fixes ring width, should not influence assembly technology, stainless steel
Fixed ring thickness is in 4mm-6mm.Stainless steel retainer ring has the advantages of anticorrosion, high intensity, and effect is that limitation HDPE flanges are swollen
It is swollen, it can also protect HDPE flange sealing flanges.Using HDPE Flanges, the dilatancy of itself makes HDPE flanges to the utility model
Sealing surface is brought into close contact, and reaches pressure piping seal request, and the HDPE liners that this utility model is applied to pressure piping connect head, can
Meet pipeline of the pressure in below 10MPa.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The HDPE Flanges of 13 stainless steel retainer ring of nonstandard 2 bolt of flat flange 4
5 recovery pipelines to be repaired.
Embodiment
It as shown is a kind of structural representation of outer fixed ring type HDPE Flange attachment means, including nonstandard flat board
Flange 1, stainless steel retainer ring 3, HDPE Flanges 4, fluted, the stainless steel retainer ring on the nonstandard flat flange 1
3 are arranged on the outside of HDPE Flanges 4 and are fixed in the groove of nonstandard flat flange 1, the nonstandard outside of flat flange 1
Bolt 2 is set to clamp HDPE Flanges 4 using its screwing force.The HDPE Flanges 4 have two, and two HDPE
The face of Flange 4 directly contacts.The fovea superior groove depth of nonstandard flat flange 1 is 3mm-5mm.DHPE Flanges 4 with it is stainless
Gap is less than 1mm between steel retainer ring 3.
When carrying out assembling even head, first HDPE Flanges 4 are made according to steel flanges size, it is desirable to HDPE Flanges
4 is cylindrical and sealing surface is clean, smooth, and two sealing surfaces of HDPE Flanges 4 are brought into close contact during assembling, and centre can not have debris,
A small amount of fluid sealant can be smeared if necessary, and stainless steel retainer ring 3 is arranged on the outside of HDPE Flanges 4, and is arranged on nonstandard flat board
In the groove of flange 1, the gap between nonstandard flat flange 1 and stainless steel retainer ring 3 not should be greater than 1mm, finally tighten bolt
2.During the pipeline normal operation repaired, pipeline internal medium pressure can expand HDPE Flanges 4, now stainless steel retainer ring
3 limitation HDPE Flanges 4 expand, and the sealing surface of two HDPE flanges 4 is closely fit together, play high pressure
The effect of sealing.Pressure can be met no more than the requirement of 10MPa pipeline rehabilitations.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
