High-safety gas cylinder body

Abstract

The invention relates to a gas cylinder, and particularly relates to a high-safety gas cylinder body. The high-safety gas cylinder body is characterized by comprising an upper half cylinder body and a lower half cylinder body, each half cylinder body comprises a head part and a ring part connected with the head part, the cross section of each ring part is annularly arranged, the axial end of each ring part is integrally connected with the head part, the ring part of one half cylinder body comprises a cone diameter section extending in the axis direction, and the inner diameter of the cone diameter section is gradually increased from close to the head part to far away from the head part. The high-safety gas cylinder body has the advantages that higher internal pressure can be borne, and the use safety can be improved.

Description

technical field [0001] The invention relates to a gas cylinder, in particular to a high-safety gas cylinder body. Background technique [0002] Gas cylinders are often used to fill medium with pressure. Gas cylinders generally include upper and lower half bottles that are welded and fixed together. The upper and lower half of the bottle body is generally stamped into a disc with a steel plate, and then stretched into an open-shaped structure through the die. The thickness of the half-bottle close to the arc transition section of the closed end will become thinner due to drawing, and the thickness of the half-bottle close to the open end will become thicker due to drawing. After the welding of the upper and lower half cylinders of the gas cylinder is completed, a filling test is required. Since the arc transition section at the upper and lower ends of the gas cylinder becomes thinner due to drawing, the final internal pressure that the gas cylinder can withstand will become ...

AI Technical Summary

Problems solved by technology

After the welding of the upper and lower half cylinders of the gas cylinder is completed, a filling test is required. Since the arc transition section at the upper and lower ends of the gas cylinder becomes thinner due to drawing, the final internal pressure that the gas cylinder can withstand will become smaller , the safety of gas cylinders becomes lower

Moreover, the stretching manufacture of the above-mentioned bottle body has certain requirements on the performance of the steel material, and the cost of the steel material is relatively high
