Abstract
The utility model discloses a plastic corrugated pipe with a flaring, which solves the problems of low speed, poor rigidity and easiness in leakage of a connecting section caused by the adoption of an online production mode in a flaring section of the conventional dual-wall corrugated pipe. A flaring section can only be formed at the interval of more than or equal to 6 meters, and a pipe with the length of 6 meters can only be cut for using when a pipe with the length of less than 6 meters is used, so that the pipe is wasted. A special pipe-expanding machine is still at the experiment stage due to memory effects and size instability of polypropylene (PP) and polyethylene (PE) materials. The plastic corrugated pipe comprises a flaring and a straight section corrugated pipe, the inner circumferential face of the flaring is tightly coated on the outer circumferential face of the straight section corrugated pipe; the outer circumferential face of the flaring is provided with a plurality of annular bumps; and the longitudinal sections of the annular bumps can be rectangular or trapezoidal. By adopting the plastic corrugated pipe with the flaring, the memory effect of plastic is eliminated, size stability, high rigidity and reliable connection are realized, and the using length can be flexibly changed according to practical production requirements, so that the conventional production line is fully utilized without investing additional equipment or labor force.
Description
Technical fieldThe utility model relates to a kind of engineering plastic film capicitor.
Background techniquePP, PE double-wall bellow flare section generally adopt two kinds of modes of production in the market, and a kind of is online production, and another kind is to adopt special-purpose flaring machine production.Speed of production is slow because the enlarging of online production exists, poor rigidity, easily cause linkage section to leak, simultaneously owing to can only make flared section of 6 meters long or more longer intervallums, 6 meters long tube can only be cut off when needing to use the pipe that is lower than 6 meter half length aborning and use, cause the waste of tubing.And there is memory effect in professional flaring machine owing to PP, PE material, and the size instability is in the experiment operational phase at present.
The model utility contentThe purpose of this utility model is to utilize existing production line, and employing method of injection molding tube joint on straight bellows is made the plastic film capicitor of band enlarging.For reaching above purpose, the utility model has adopted following technological scheme:. a kind of plastic film capicitor with enlarging, comprise enlarging and flat segments bellows, its feature is: the inner peripheral surface of enlarging closely coats the outer peripheral surface of flat segments bellows.The outer peripheral surface of enlarging is provided with many annular projections.It is trapezoidal that the longitudinal cross-section of annular projection can be that rectangle also can be made as.
Adopt the plastic film capicitor of the band enlarging of above technological scheme, eliminated the memory effect of plastics, have dimensionally stable, rigidity big, connect reliably, use length to change flexibly according to demand of practical production, thereby make full use of existing production line, do not need other used device with artificial.
Description of drawingsFig. 1 is a kind of plastic film capicitor structural representation with enlarging of the utility model.
Fig. 2 is a kind of plastic film capicitor structure shaft side figure with enlarging of the utility model.
EmbodimentAt first production flat segments bellows 1, bellows 1 is not with enlarging 2, and bellows 1 can cut into different length as required.Adopt special injection mould to outpour enlarging 2 then in the one or both ends of bellows 1.Many annular projections 3 are arranged in the enlarging 2.The effect of projection 3 is the rigidity that strengthen enlarging 2, to reach the purpose of saving material.Because bellows 1 is to fuse into one under the injecting condition of high temperature, high pressure with enlarging 2, eliminated as defectives such as welding, do not have and leak, can improve the voltage withstand class when using.
