High strength corrugated pressure bottle

Abstract

The invention relates to a pressure vessel, in particular to a high-strength corrugated pressure bottle. A high-strength corrugated pressure bottle is characterized in that it includes a bottle body, the bottle body includes a sealing head located at the end and a bottle body with the same cross-sectional shape and size everywhere, and the sealing head is formed with a body facing the bottle. A groove-shaped structure on the side, the sealing head is composed of an inner circular part and an outer ring part, the axis of the bottle body part is located on the inner circular part, and the outer ring part is connected to the outer circumferential side of the inner circular part, so The outer ring portion is connected with the bottle body portion, and the outer ring portion has a plurality of inner concave ring segments adjacent to the bottle body portion. The outer ring portion is concave to form the inner concave ring segment, and the inner concave ring segment surrounds the outer ring portion once. The invention has the advantages of being able to withstand higher internal pressure and improving the safety of use.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a high-strength corrugated pressure bottle. Background technique [0002] The pressure bottle is often used for filling the medium with pressure. The pressure bottle generally includes two upper and lower half-bottles that are welded and fixed together. The upper and lower half of the bottle body is generally punched from a steel plate into a round sheet by a die, and then stretched into an open structure through the die. The thickness of the arc transition section near the closed end of the half bottle body will become thinner due to drawing, and the thickness of the half bottle body near the open end will become thicker due to drawing. After the welding of the upper and lower half-bottles of the pressure bottle is completed, a filling test is required. Since the arc transition sections at the upper and lower ends of the pressure bottle become thinner due to drawing, the final internal pres...

AI Technical Summary

Problems solved by technology

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