The utility model discloses under the unchangeable condition of assurance pressure bottle maximum internal diameter, reduce the internal diameter of head and section of thick bamboo portion junction through setting up annular interior concave section to the internal diameter size that makes head and section of thick bamboo portion junction changes gradually, enables head and section of thick bamboo portion junction atress more even, with the internal pressure that further improves head and section of thick bamboo portion junction and can bear. The utility model discloses a pressure bottle can change the internal diameter after drawing the punching press, can improve tensile properties, reduces the elongation requirement to the material, reduces the steel requirement, can reduce tensile attenuate volume, can improve the thickness of head and section of thick bamboo portion junction to further improve the security performance, the physical stamina bears higher internal pressure. When filling the inspection to the pressure bottle, along with the increase of internal pressure, the volume of pressure bottle can warp to the biggest to slow down the rise of pressure, when internal pressure exceeded a definite value, the pressure bottle volume can not change because of non-plastic deformation, can avoid filling too much, can effectively reduce the filling coefficient of bottle so that the bottle is in safe state. The annular concave section can be obtained by cold working, the strength of the pressure bottle can be further improved, and the pressure bottle can bear higher internal pressure. Wherein the inner circle is used for installing the valve.
Preferably, a first arc-shaped transition section is formed between two adjacent annular concave sections, and the plurality of annular concave sections and the plurality of first arc-shaped transition sections form a wavy structure. The arrangement makes the stress on all parts of the outer ring part more uniform.
Preferably, the annular concave section closest to the cylindrical portion is smoothly connected with the cylindrical portion and forms a second arc-shaped transition section, and the annular concave section closest to the inner circle portion is smoothly connected with the inner circle portion and forms a third arc-shaped transition section. The arrangement makes the stress on the connecting part of the inner circle part and the outer circle part more uniform.
Preferably, the heights of the plurality of annular concave sections gradually increase from the cylinder portion side to the inner circle portion side. The arrangement facilitates the processing and manufacturing of the annular concave section. The thickness of the outer ring part from the inner circle part to the cylinder part side is gradually reduced, the height (depth) of the annular inner concave section is gradually increased from the cylinder part side to the inner circle part side, and the stress of the outer ring part can be balanced, so that the outer ring part bears more uniform pressure.
Preferably, the curvature of the annular concave sections is larger from the cylinder part side to the inner circular part side. The annular concave section is convenient to process and manufacture, and the stress of the outer ring part can be balanced, so that the pressure of the outer ring part is more uniform.
Preferably, the axis of the annular concave section is coaxial with the axis of the cylinder part. The arrangement can balance the stress of all parts of the outer ring part, so that all parts of the outer ring part bear more uniform pressure.
