Abstract
The utility model discloses a hard and soft PVC composite co-extruded corrugated flexible pipe, mainly consisting of a pipe body. The inner wall of the pipe body along the axial direction is a soft PVC layer, and the corrugation outside the pipe body is a hard PVC reinforcing rib; the hard PVC rib is provided with a bottom surface which is connected with the welded material in the mold of the outer surface of the soft PVC layer. Compared with common corrugated pipes, the utility model has the advantages of high internal and external pressure bearing, good strength, long service life, a smooth inner diameter, less pollution of products manufacture, and low equipment investment for large caliber production.
Description
Technical field
The utility model relates to a kind of corrugated flexible hose, mainly is a kind of hard soft pvc composite co-extruding corrugated flexible hose.
Background technique
Common bellows adopts the plastic bonding kinking to form, and perhaps a kind of raw material is extruded, perhaps plastics sucking moulding; Its deficiency is: pressure ratio is more common inside and outside bearing, intensity is general.
Summary of the invention
The utility model will solve the defective of above-mentioned prior art, and a kind of hard soft pvc composite co-extruding corrugated flexible hose is provided.
The utility model solves the technological scheme that its technical problem adopts.This hard soft pvc composite co-extruding corrugated flexible hose mainly comprises body, and inboard wall of tube body is the flexible PVC layer vertically, and the outer ripple of its body is the hard PVC stiffening rib; Described hard PVC stiffening rib has the interior fusion of the appearance face mould of bottom surface and flexible PVC layer to link together.
The effect that the utility model is useful is: adopt this structure, it than common bellows have bear in external pressure height, intensity good, long service life, internal diameter is smooth, pollutes fewly when product is made, equipment investment was low when heavy caliber was produced.

Fig. 1 is main TV structure schematic representation of the utility model embodiment 1;
Fig. 2 is that the TV structure schematic representation is amplified in the utility model embodiment 1 part;
Fig. 3 is main TV structure schematic representation of the utility model embodiment 2;
Fig. 4 is that the TV structure schematic representation is amplified in the utility model embodiment 2 part;
Description of drawings: body 1, flexible PVC layer 1-1, hard PVC stiffening rib 2, cavity 2-1;
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment 1: this hard soft pvc composite co-extruding corrugated flexible hose, mainly comprise body 1, and body 1 inwall is flexible PVC layer 1-1 vertically, its body 1 outer ripple is a hard PVC stiffening rib 2; Fusion links together in described hard PVC stiffening rib 2 bottom surfaces and the flexible PVC layer 1-1 appearance face mould.The cross section of described hard PVC stiffening rib 2 is a hollow tubular, and being shaped as of hollow tubular is trapezoidal, includes a cavity 2-1 in it.
During use, do not lose under the round situation at the pipe endoporus, can be crooked arbitrarily, bending radius is little, can be widely used in fields such as ventilation, mass transport (powdery, granule), flow of fluid.
Embodiment 2: the cross section of described hard PVC stiffening rib 2 is solid half round post.
