Abstract
The utility model discloses a kind of HDPE and be wound around bellows, comprise the pipeline being formed by heterotypic strip spiral winding, described heterotypic strip both sides are gap junction point, described gap junction point is provided with knitting layer, described heterotypic strip comprises inner-walls of duct, and described inner-walls of duct is provided with two hollow boss, and described two hollow boss form the ripple projection of pipeline, described two hollow boss are connected as one by changeover portion, and described two hollow boss inside are equipped with oblique stiffening rib.The utlity model has high ring stiffness, outer wall is made to bellows-shaped, alleviated the weight of tubing, simple and beautiful structure simultaneously.
Description
Technical field
The utility model relates to the technical field that bellows is relevant, more specifically, relates to a kind of HDPE and is wound around bellows.
Background technique
At present, the domestic steel plastic drain pipe as shown in Figure 1 that generally uses, its advantage is that ring stiffness is high, but Shortcomings part: the one, Young's modulus and the thermal expansion coefficient of plastics and steel have big difference, and easily cause tube wall cracking under interior External Force Acting; The 2nd, the poor corrosion resistance of steel, once that steel band is corroded is fragile, thereby affects the use of pipeline; The 3rd, complex forming technology.
And the particularly double-wall corrugated pipes as shown in Figure 2 of pure HDPE pipe that adopt on existing market, it is the mode through extruder for shaping by raw material, through mould and corrugated pipe forming machine, produces. moreBut the double-wall corrugated pipe that traditional mode of production is produced exists following shortcoming: 1, ring stiffness is good not, can not bear larger soil load forces; 2, manufacturing equipment is expensive, has high input; 3, be difficult to make large diameter pipeline.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of HDPE and is wound around bellows, solves traditional steel and moulds easily corrosion of pipe, and corrugated pipe ring rigidity is good not, and difficulty is made the problem of large diameter pipeline.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
HDPE is wound around a bellows, comprises the pipeline being formed by heterotypic strip spiral winding,
Described heterotypic strip both sides are gap junction point, described gap junction point is provided with knitting layer, described heterotypic strip comprises inner-walls of duct, described inner-walls of duct is provided with two hollow boss, described two hollow boss form the ripple projection of pipeline, described two hollow boss are connected as one by changeover portion, and described two hollow boss inside are equipped with oblique stiffening rib.
Preferably, described knitting layer is the stiffening rib perpendicular to inner-walls of duct surface, and it is face contact with contacting of adjacent hollow boss, this makes mating face between heterotypic strip that the utility model is adjacent be far longer than the winding structure bellows of all other types, it engages effect is best in all winding bellowss, thereby makes the product of the utility model method gained have higher intensity.
Preferably, described hollow boss sectional shape is fan-shaped, when two adjacent fan-shaped hollow boss are connected after joint by stiffening rib, make pipeline form bellows-shaped, or described hollow boss sectional shape is square with an arcuate segment, equally also can make pipeline form bellows-shaped, now above-mentioned changeover portion belongs to a part for inner-walls of duct.The shape of two kinds of hollow boss of the utility model all has arcuate structure to exist, so not only attractive in appearance in structure, and the pipeline forming is round and smooth, without corner angle, is difficult for hurting sb.'s feelings.
The beneficial effect that the utility model compared with prior art has: by added the stiffening rib of a vertical stiffening rib and two inclinations in the middle of bellows crest, improved the ring stiffness of bellows, outer wall is made to bellows-shaped, alleviated the weight of tubing, simple and beautiful structure simultaneously.
