Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the partial sectional view of pipeline in the present invention;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the partial sectional view of pipeline in the present invention; Fig. 2 is the A portion enlarged view of Fig. 1.As depicted in figs. 1 and 2, pipeline 100 of the present invention at least comprises interconnective the first pipe section 101 and second pipe section 102, only shows in the drawings two pipe sections, but can comprise in other embodiments plural pipe section.The internal diameter of each pipe section 101,102 is identical, can be plastic pipe or the multiple tube that accompanies steel band, but the internal surface of each pipe section is plastic interior surfaces.
The internal surface of the adjacent end portion of first, second pipe section 101,102 forms join domain 103 jointly.For fear of the impact of temperature, between the adjacent end portion of first, second pipe section 101,102, the reserved flexible gap that is not less than 30mm.Thereby pipeline 100 also comprise by foamed glue 104 be bonded in the PE(polyethylene that the internal surface of first, second pipe section 101,102 links together two pipe sections 101,102) connecting band 105.This PE connecting band 105 is annular perpendicular to the axial cross section of pipeline 100.According to the caliber of pipeline 100, can select the PE connecting band 105 of different size specification.When bonding, first spray foamed glue 104 at the join domain 103 of first, second pipe section 101,102 internal surfaces, afterwards PE connecting band 105 is held round and is fitted on the internal surface that is sprayed with foamed glue 104.
Pipeline 100 also comprises for auxiliary PE connecting band 105 is fixed to the link 106 on first, second pipe section 101,102 inwalls, and this link 106 can be tapping screw, and its quantity is multiple, to be equidistantly arranged on PE connecting band 105.
Because pipeline 100 is usually used in carrying the liquid such as potable water, these liquid inevitably can be interior to exosmosis from pipeline 100.In the time that liquid infiltrates into foamed glue 104 by the gap between for example link 106 and PE connecting band 105, foamed glue 104 meeting imbibitions, fully fill gap, thereby strengthen the water-proof performance of pipeline 100.
Between the two ends and first, second pipe section 101,102 internal surfaces of PE connecting band 105, may there is small gap, in order to strengthen waterproof, the two ends of PE connecting band 105 are welded on respectively the internal surface of first, second pipe section 101,102 by PE scolder 107.
The connecting means of pipeline 100 of the present invention is below described.This connecting means mainly comprises the following steps:
Inspection before S0, connection, whether the tubing inner and outer surface that first checks first, second pipe section 101,102 smooth, have or not breakage, have no concave-convex or steel band exposed (for the multiple tube that accompanies steel band), if there is steel band exposed, whether repair welding is smooth to prevent PE scolder that steel band is exposed.Foreign material in first, second pipe section 101,102 are removed to the pipe end join domain of clean first, second pipe section 101,102;
S1, the pipe end of first, second pipe section 101,102 is aligned, make both axis straight and be located along the same line, and reserve the flexible gap that is not less than 30mm.
S2, at the internal surface mark foamed glue spray regime terminated line of first, second pipe section 101,102, this foamed glue spray regime is advisable than the little 15-20mm of the lay length of actual PE connecting band 105, to reserve the follow-up welding job district that PE connecting band 105 is welded.Afterwards, use the foam gun through cleaning that foamed glue 104 is injected in the join domain of first, second pipe section 101,102 internal surfaces equably along circumferencial direction, spray regime must not exceed foamed glue spray regime terminated line.In practice of construction process, can as required, regulate the flow control valve of foam gun, thereby adjust the colloid flow of foamed glue.
S3, use supporting facility hold round PE connecting band 105 exert pressure, make it be fitted in the join domain 103 of first, second pipe section 101,102 internal surfaces that spray foamed glue 104, use rubber mallet to knock the internal surface of PE connecting band 105, knock dynamics appropriateness, guarantee PE connecting band 105 is evenly fitted with foamed glue 104, thereby first, second pipe section 101,102 is linked together.PE connecting band 105 and foamed glue 104 bonding operates in 20 minutes and completes with interior, cannot fit avoiding after foamed glue 104 dry tack frees.
S4, spacing to be scheduled to, adopt link 106 that first, second pipe section 101,102 internal surfaces are locked and be fixed on to PE connecting band 105 along circumferencial direction.In order to improve speed of application and to reduce labor intensity, in the situation that link 106 be tapping screw, can adopt electric screwdriver or fixed criticize, the operation tool such as square pneumatic screwdriver tightens tapping screw.Because first, second pipe section 101,102 internal surfaces are frosting, PE connecting band 105 is PE material, the gear control of operation tool is preferably controlled at low and middle-grade, then the moment of torsion of adjusting gradually screw as initial value using 1.5-1.6Nm is to desired value, to prevent first, second pipe section 101,102 or PE connecting band 105 ftractures and the sliding teeth of link 106.
S5, with icroextrusion machine or EVA welding gun, use end and first, second pipe section 101, the 102 inwall joints of PE scolder to PE connecting band 105 to carry out circumference soldering and sealing sealing.Complete the connection of first, second pipe section 101,102.
Compared with prior art, pipeline 100 of the present invention does not need special energising equipment, has exempted the hard works such as carrying, and the connection between each pipe section is very convenient, easy to operate, and the pipeline 100 obtaining has good water-tight performance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
