Abstract
The utility model discloses a compound high pressure air bottle with orthogonal winding. The external surface of the liner of the bottle body is wound with reinforced fiber, and the reinforced fiber is wound along the shaft of the external surface of the liner of the bottle body to form the shaft direction ply. The reinforced fiber is still wound along the circumferential direction of the external surface of the liner of the bottle body with cylinder shape to form the circumferential direction ply. The winding directions of the strengthen fiber of the two plies are orthogonal; The semi-ball shape sealing heads at the two ends of the liner of the bottle body are provided with an upper and lower button covers, and concave surface of inner side of the upper and lower button cover is connected with the convex shape external surface of the liner semi-ball shape sealing head of the bottle body; The upper and lower button covers are cut with gaps with groove shape to form the inverted hooks with corresponding number, and the reinforced fiber forms a return winding through the inverted hooks to form the shaft direction ply. The utility model has advantages of light weight and anti-high pressure.
Description
The utility model relates to gas cylinder, the composite high pressure gas cylinder that specifically a kind of quadrature twines.
In the prior art, gas cylinder fills gas or gas-liquid mixed material, and has very big internal pressure.The suffered internal pressure of gas cylinder can be decomposed into two-part: the one, along the circumferential direction distribute perpendicular to the bottle inwall, and the 2nd, distributing vertically applies pressure to the internal surface at bottle two end part.General gas cylinder adopts steel material, though firm weight is big, and the employing aluminum alloy material that has, intensity is not good enough again.So people are at the composite cylinder of seeking lightweight material and tolerance high pressure.Common composite cylinder adopts, and to be reinforcing fiber walk around two ends and twine with axis oblique overlapping at an angle along the bottle outer wall, adds the circumference winding method of upper edge bottle outer wall.Because what this fiber twined that the structure that strengthens exists oblique extension and fiber is stacked with phenomenon repeatedly, not only wasted fiber, increased own wt, and failed to give full play to the high potentiality of tensile strength of fiber, so the bottle withstand voltage properties is undesirable.
The purpose of this utility model provides the composite high pressure gas cylinder that a kind of light-duty, high voltage bearing quadrature twines.
To achieve these goals, the technical solution of the utility model is: have tubular bottle liner, bottle liner outer surface is fiber-reinforced wrapped, it is characterized in that: described reinforcing fiber axially twines along tubular bottle liner appearance, constitute axially shop layer, described reinforcing fiber also twines along the circumferencial direction of bottle liner outer surface, constitutes circumferentially shop layer, and the direction that described two shop layer reinforcing fiber twine is a quadrature; The hemispherical head at described bottle liner two ends is provided with the upper and lower buckle closure of two High Strength Steel materials, the closely connected connection of convex external surface of the inboard recessed surface of upper and lower buckle closure and bottle liner hemispherical head; Cut the flute profile breach on the upper and lower buckle closure, and formed the barb of respective number, the reinforcing fiber that is stained with resin is back and forth twined by barb and is constituted axial shop layer;
Described reinforcing fiber is carbon fiber, glass fibre or aramid fibre; Described bottle liner (1) is aluminum alloy or titanium alloy material.
The utlity model has following advantage:
1. own wt is light.The bottle liner that the utility model adopts light alloy material (being generally aluminum alloy) to make has played the supporting effect that prevents gas leakage and twining when in composite high pressure gas cylinder.Owing to adopt the quadrature of reinforcing fiber to twine, the suffered stress of bottle liner almost completely is delivered on the buckle closure that fiber with humidification and high-strength material make, therefore, and concerning high-pressure bottle, the wall thickness of bottle liner can attenuate, can alleviate own wt significantly.
2. high-voltage resistance capability is strong.The utility model is structurally fiber-reinforced wrapped from the circumferential and axial quadrature of bottle liner outer surface, canoe is more optimized, after tubular bottle liner bears the internal pressure of gas, stress is vertically born by the fiber of axial shop layer and the shop layer fiber of circumferencial direction respectively with stress along the circumferential direction, given full play to the humidification of fiber, so have high voltage bearing characteristics.
Fig. 1 is the utility model structural representation.
Fig. 2 is the section of structure of buckle closure under the utility model.
Below in conjunction with accompanying drawing the utility model structure and working principle are described in further detail.
As shown in Figure 1, 2, has tubular bottle liner, bottle liner outer surface is fiber-reinforced wrapped, described reinforcing fiber axially twines along bottle liner 1 appearance, constitute axially shop layer 4, described reinforcing fiber also twines along the circumferencial direction of tubular bottle liner 1 outer surface, constitutes circumferentially shop layer 3, and the direction that described two shop layer reinforcing fiber twine is a quadrature; The hemispherical head at described bottle liner 1 two ends is provided with the upper and lower buckle closure 2,5 of two High Strength Steel materials, the closely connected connection of convex external surface of the inboard recessed surface of upper and lower buckle closure 2,5 and bottle liner 1 hemispherical head; Cut the flute profile breach on the upper and lower buckle closure 2,5, and formed the barb of respective number, the reinforcing fiber that is stained with resin is back and forth twined by barb and is constituted axial shop layer; The described bottle liner 1 of present embodiment adopts aluminum alloy material, and described reinforcing fiber is a carbon fiber.
The utility model working principle is: after tubular bottle liner 1 bore the internal pressure of gas or liquid, stress vertically and stress were along the circumferential direction born by the reinforcing fiber of the shop layer 3 of the reinforcing fiber of axial shop layer 4 and circumferencial direction respectively; The shop layer 3 that the reinforcing fiber that twines along bottle liner 1 circumferencial direction constitutes is used to bear owing to press the circumferential stress that causes in the cylindrical shell, because the circumferential stress along the cylindrical shell diverse location distributes different, the thickness that twines shop layer 3 can correspondingly thicken or attenuate, effectively utilize fiber and alleviate the bottle own wt thereby reach, by upper and lower buckle closure 2,5 reinforcement of two High Strength Steel materials, the convex external surface of the recessed surface of upper and lower buckle closure 2,5 and bottle liner 1 hemispherical head is closely connected to transmit stress respectively for the hemispherical head at bottle liner 1 two ends.
Tubular bottle liner 1 described in the utility model also can be light alloy materials such as titanium alloy; Described fiber also can adopt glass fibre, aramid fibre; Described bottle liner 1 bottom also can be flat bottom cover, and following buckle closure 5 is also established flat cooperation with it.
