Abstract
A novel steel band reinforced polyethylene spiral bellows structure comprises a plastic inner tube, a finished steel band with outer flanges on both sides, and an outer plastic layer, wherein the finished steel band is equidistantly wound on the outer surface of the plastic inner tube and is coated with the outer plastic layer. A thickened layer is arranged on the contact portion of the plastic inner tube with the finished steel band. The interspace portions of presser feet of the outer flanges of adjacent two circles of the finished steel band are bonded through the outer plastic layer and the inner wall of the inner plastic tube. The combined stress cracking resistance of the outer flanges of the finished steel band can be improved by increasing the thickness between the plastic inner tube and the presser feet of the outer flanges of the finished steel band, so that the cracking resistance of the inner wall can be enhanced, and the service life of bellows can be prolonged.
Description
Technical field
The utility model relates to tubing technical field, particularly relates to a kind of steel band reinforced polyethylene spiral ripple pipe structure.
Background technique
Ring stiffness is high, easy to connect, low cost and other advantages owing to having for steel band reinforced polyethylene spiral ripple pipe, is used as more and more buried draining, the blow-off line in the fields such as urban construction at present.At present, the mode of production of existing steel band reinforced polyethylene spiral ripple pipe is by production line, PE being expected and the moulding of steel band melting composite winding.What mainly play rigidity effect is shaped-steel strip, and shaped-steel strip and plastic inner pipe bond locations need to reach certain thickness requirement just can support steel band, makes tubing reach certain ring stiffness.Because plastic inner pipe material bonding place thickness is not enough, easily cause pipe material inner wall cracking, tubing is declined working life.
Notification number CN 202109107 U disclose a kind of steel band reinforced polyethylene spiral ripple pipe, this model utility by shaped-steel strip flanging be connected mutually laminating of steel band, to increase the thickness of shaped-steel strip and plastic inner pipe bond locations.This model utility complex structure, and on the thickness of bonding place to shaped-steel strip be connected laminating of steel band and require too high.
Model utility content
The purpose of this utility model is to address the above problem and is not enough, provides a kind of and can improve pipe intensity, and inwall is not easy to crack, non-leakage, the steel band reinforced polyethylene spiral ripple pipe of long service life.
The technical solution of the utility model is, a kind of new steel belt enhanced polyethylene helical corrugation tubular construction, comprise plastic inner pipe, shaped-steel strip and outer plastic layer, the equidistant outer surface that is wound in plastic inner pipe of shaped-steel strip, shaped-steel strip outer cladding outer plastic layer, the position that plastic inner pipe contacts with shaped-steel strip is provided with thickening layer.This thickening layer can avoid shaped-steel strip in the past directly to contact with plastic inner pipe outer surface, thereby by increasing the thickness at plastic inner pipe and shaped-steel strip flange presser feet place, improve the ability of the resistance to combined stress cracking in shaped-steel strip flange place, make the working life of inwall raising tubing not easy to crack.
Further, the outside of shaped-steel strip is coated outer plastic layer, bonds together with the inwall of plastic inner pipe.Thereby the effect of outer plastic layer is to carry out bonding fixedly steel band by the inwall with plastic inner pipe, makes it not yielding.
Further, the position, space between the flanging presser feet of two adjacent rings shaped-steel strip, the inwall by plastic outer layer and plastic inner pipe is bonded together.Effect is to prevent strip deformation.
Further, shaped-steel strip be sectional shape be both sides with the U-shaped profiled strip of flanging, and be coated with adhering resin outward at this shaped-steel strip.Between steel band and outer plastic layer, there is a transition layer, at steel band, apply adhering resin outward, steel band and plastics are closely bonded, prevent the corrosion of water and air to steel band simultaneously.
The utility model has the advantage of: only need, by the appropriate steel band presser feet of tubing and the PE thickness at plastic inner pipe link position place of increasing, can improve the certain ring stiffness of tubing, improve the stability of pipe workpiece quality.The maintenance cost that minimizing causes because of inwall cracking, and after thickness increase, greatly increase the working life of tubing.
Accompanying drawing explanation
Fig. 1: be longitudinal sectional drawing of the present utility model.
Fig. 2: the sectional drawing thickening for two adjacent rings shaped-steel strip presser feet place.
In figure, be labeled as: 1, plastic inner pipe, 2, shaped-steel strip, 3, outer plastic layer, 4, thickening layer.
Specific embodiments
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment as shown in Figure 1, the utility model adopts hot extrusion winding shaping process to make.By internal layer molding port mould, hot extrusion goes out the structure of plastic inner pipe 1, then on the equidistant both sides that are wound with of outer surface of plastic inner pipe 1 with the shaped-steel strip of flanging, as shown in Figure 2, it is the enlarged view of A part in Fig. 1, shaped-steel strip flange presser feet is pressed and to be fallen within on the outer surface that plastic inner pipe 1 thickens, then at shaped-steel strip outer cladding outer plastic layer 3, plastic inner pipe 1 connects together with outer plastic layer 3 cementations simultaneously.
Before the description of better case study on implementation is provided so that any technician of related domain uses or utilize the utility model better, institute it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to the utility model.To this better case study on implementation; those skilled in the art are not departing from the basis of the utility model principle; can make various modifications or conversion, any modification of making, be equal to replacement, improvement etc., be interpreted as these modifications or conversion does not depart from protection domain of the present utility model.
