According to pipeline described in the utility model, described pipeline also comprises for the link on the auxiliary inwall that described PE connecting band is fixed to described first, second pipe section.
According to pipeline described in the utility model, described link is tapping screw.
According to pipeline described in the utility model, described link is with equidistant arrangement.
According to pipeline described in the utility model, the two ends of described PE connecting band are welded on described first, second side opposite by the PE scolder respectively.
Implement pipeline of the present utility model, have following beneficial effect: pipeline of the present utility model does not need special-purpose energising equipment, has exempted hard works such as carrying, and the connection between each pipe section is very convenient, easy to operate, and the pipeline that obtains has good water-tight performance.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the partial sectional view of pipeline in the utility model;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 is the partial sectional view of pipeline in the utility model; Fig. 2 is the A portion enlarged view of Fig. 1.As depicted in figs. 1 and 2, pipeline 100 of the present utility model comprises interconnective first pipe section 101 and second pipe section 102 at least, only shows two pipe sections in the drawings, but can comprise plural pipe section in other embodiments.Each pipe section 101,102 internal diameter are identical, can be plastic pipe or the multiple tube that accompanies steel band, but the internal surface of each pipe section are plastic interior surfaces.
The internal surface of first, second pipe section 101,102 adjacent end portion forms join domain 103 jointly.For fear of Temperature Influence, between first, second pipe section 101,102 adjacent end portion, reserve the flexible gap that is not less than 30mm.Thereby pipeline 100 also comprise by foamed glue 104 be bonded in the PE(polyethylene that first, second pipe section 101,102 internal surface link together two pipe sections 101,102) connecting band 105.This PE connecting band 105 is annular perpendicular to pipeline 100 axial cross sections.According to the caliber of pipeline 100, can select the PE connecting band 105 of different size specification.When bonding, at the join domain 103 spray foamed glues 104 of first, second pipe section 101,102 internal surfaces, afterwards PE connecting band 105 held round and is fitted on the internal surface that is sprayed with foamed glue 104 earlier.
Because pipeline 100 is usually used in carrying liquid such as potable water, these liquid inevitably can be interior to exosmosis from pipeline 100.When liquid infiltrated into foamed glue 104 by the gap between for example link 106 and the PE connecting band 105, foamed glue 104 meeting imbibitions were fully filled the gap, thereby are strengthened the water-proof performance of pipeline 100.
Between the two ends of PE connecting band 105 and first, second pipe section 101,102 internal surfaces, may there be small gap, in order to strengthen waterproof, the two ends of PE connecting band 105 are welded on first, second pipe section 101,102 internal surface by PE scolder 107 respectively.
The below connecting means of explanation pipeline 100 of the present utility model.This connecting means mainly may further comprise the steps:
Inspection before S0, the connection, check earlier whether first, second pipe section 101,102 tubing inner and outer surface be smooth, have or not breakage, no concave-convex or steel band exposed (for the multiple tube that accompanies steel band) are arranged, if there is steel band exposed, whether repair welding is smooth then to prevent the exposed PE scolder of steel band.First, second pipe section 101, foreign material in 102 are removed, cleaned first, second pipe section 101,102 pipe end join domain;
S1, first, second pipe section 101,102 pipe end are 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 first, second pipe section 101,102 internal surface mark foamed glue spray regime terminated line, this foamed glue spray regime is advisable than the little 15-20mm of 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 join domain with first, second pipe section 101,102 internal surfaces equably along circumferencial direction, spray regime must not surpass foamed glue spray regime terminated line.In the practice of construction process, can regulate the flow control valve of foam gun as required, thereby adjust the colloid flow of foamed glue.
S3, use supporting facility hold round PE connecting band 105 and exert pressure, make it be fitted in first, second pipe section 101 that sprays foamed glue 104, the join domain 103 of 102 internal surfaces, use rubber mallet to knock the internal surface of PE connecting band 105, knock the dynamics appropriateness, assurance 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 finishes with interior, can't fit after foamed glue 104 dry tack frees avoiding.
S4, with predetermined spacing, adopt link 106 with PE connecting band 105 along circumferencial direction locking and be fixed on first, second pipe section 101,102 internal surfaces.In order to improve speed of application and to reduce labor intensity, be under the situation of tapping screw at link 106, can adopt electric screwdriver or criticize surely, 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 the PE material, the gear control of operation tool is preferably controlled low and middle-grade, the moment of torsion of adjusting screw gradually then as initial value with 1.5-1.6Nm is to desired value, to prevent first, second pipe section 101,102 or PE connecting band 105 crackings and link 106 sliding teeth.
S5, with miniature extruder or EVA welding gun, use the PE scolder that circumference soldering and sealing is carried out with first, second pipe section 101,102 inwall joints in the end of PE connecting band 105 to seal.Finish first, second pipe section 101,102 connection.
Compared with prior art, pipeline 100 of the present utility model does not need special-purpose energising equipment, has exempted hard works such as carrying, and the connection between each pipe section is very convenient, and is easy to operate, and the pipeline 100 that obtains has good water-tight performance.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
