The invention provides a high-pressure gas bottle which is used for storing high-pressure fluids. The high-pressure gas bottle comprises an inner container and an effective prestressed steel wire winding layer, wherein the effective prestressed steel wire winding layer winds around the external surface of the inner container and is formed by winding steel wires with preset rated value of tension around the inner container, and the preset rated value is controlled to enable the calculation stress of all parts of the inner container to be approximately the same under the idle condition and the full load condition. Because the wound steel wires have high strength value and creeping threshold value, the strength of the steel wire layer is ensured. Meanwhile, because the steel wire winding layer and the inner container are parallel structures made of materials with the same elastic modulus, the fatigue life is prolonged, and the danger that the gas bottle burst suddenly due to the rapid crack propagation of the inner container is eliminated. Thus, the high-pressure gas cylinder can furthest reduce the usage amount of the materials, and the safety performance of the high-pressure gas cylinder is improved at the same time.
Description
technical field [0001] The invention relates to a high-pressure container, in particular to a high-pressure gas cylinder for storing and transporting compressed natural gas (CNG), hydrogen and other high-pressure gases. Background technique [0002] Large-scale high-pressure gas cylinders, especially CNG large-scale high-pressure gas cylinders (with a water volume of more than 450 liters), are currently still seamless containers of integral structure made of alloy seamless steel pipes through spinning and quenching and tempering. When fully loaded, the tangential tensile stress on the inner surface is very large: the calculated stress (such as mises stress) has reached the allowable engineering stress; and at the parts far away from the two ends of the cylinder, the axial stress is very small, so the mises stress is only Reaching 1 / 2 of the allowable stress, even the mises stress at both ends of the cylinder is only 2 / 3 of the allowable stress. In different parts of the gas...
