Abstract
A galvanized steel strip enhanced polyethylene helical bellows relates to a steel strip enhanced polyethylene helical bellows, in particular to a galvanized steel strip enhanced polyethylene helical bellows structure. The utility model provides the galvanized steel strip enhanced polyethylene helical bellows which is high in ring stiffness, external force shock resistance, bonding performance and corrosion resistance and low in bellows weight of every square meter and cost. The polyethylene helical bellows comprises an inner layer and an outer layer, wherein reinforcing steel strips are arranged between the inner layer and the outer layer; and the polyethylene helical bellows is characterized in that sections of the reinforcing steel strips are isosceles-trapezoid-shaped; the top length of each isosceles trapezoid is 40%-60% longer than the bottom length of the isosceles trapezoid; an included angle between two waists of the isosceles trapezoid is 20 to 30 degrees; the reinforcing steel strips are galvanized steel strips; and both the inner layer and the outer layer are made of an HDPE (high density polyethylene) material.
Description
Technical field
The utility model relates to a kind of steel band reinforced polyethylene spiral ripple pipe, and especially a kind of Galvanized Steel Strip strengthens the polyethylene helical bellows structure.
Background technique
At present, the steel band enhanced polyethylene of selling on the market (PE) helical bellows, cementability is poor, a little less than the anti-corrosion capability, ring stiffness is not high, and ring stiffness grade maximum can only reach SN16, crest is higher, last ripple is wide be down ripple wide 65%～75%, steel band reinforced polyethylene spiral ripple pipe crest number distributes more relatively, cause the outer wall thickness ununiformity even, not only the tubing ring stiffness is low, and external shock resistance ability is poor, anti-corrosion capability is poor, cementability is bad, and tubing rice is heavy bigger, the cost height.
In addition, at present inner wall material and outer layered material are all made with common steel band is compound, and itself and steel band bonding force are lower, and stress is big, and surperficial easy to crack, and quality of product is difficult to assurance.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of ring stiffness height is provided, and external shock resistance ability is strong, and cementability is strong, and corrosion resistance is strong, and tubing rice is heavily low, and the Galvanized Steel Strip that cost is low strengthens polyethylene helical bellows.
For realizing above-mentioned purpose of the present utility model, adopt following technological scheme, the utility model comprises internal layer and skin, be provided with the reinforcement steel band between internal layer and the skin, it is characterized in that: the cross section of strengthening steel band is isosceles trapezoid, the top length of isosceles trapezoid equals 40%～60% of end length, and angle is 20 °～30 ° between two waists of isosceles trapezoid; Described reinforcement steel band is Galvanized Steel Strip; Described internal layer and skin are high density polyethylene (HDPE) (HDPE) material.
As a kind of preferred version of the present utility model, the top length that described isosceles trapezoid is strengthened steel band equals 1/2nd of end length.
As another kind of preferred version of the present utility model, angle is 30 ° between reinforcement steel band two waists of described isosceles trapezoid.
The beneficial effects of the utility model: the top length that the utility model is strengthened steel band by isosceles trapezoid is set to 40%～60% of end length, angle is set to 20 °～30 ° between two waists of isosceles trapezoid reinforcement steel band, reduced the height of crest, thereby reach the purpose that improves ring stiffness, reduce rejection number, improved economic benefit.
Simultaneously, the utility model has also reduced the number of crest, and outer layer thickness is even, reaches to improve ability and the heavy purpose of reduction tubing rice that external force resistance impacts.
In addition, the utility model is simple in structure, and is with low cost.
Reinforcement steel band of the present utility model is Galvanized Steel Strip, and Galvanized Steel Strip can improve the bonding strength of strengthening between steel band and internal layer and the skin; Internal layer and outer compound with Galvanized Steel Strip can strengthen the corrosion resistance between internal layer and outer and the reinforcement steel band, and the stress that reduces steel band is concentrated, and in addition, the skin of high-density polyethylene material and internal layer also have advantage not easy to crack, good product quality.
Measure through check, when angle was 30 ° between 1/2nd, two waists that the top length of isosceles trapezoid reinforcement steel band equals to grow at the end, pipe ring rigidity was the highest, can reach 20kN/ ㎡.
