Abstract

The invention discloses a method for weakening deformation of pressure vessel flap in storage and transportation states, and relates to the technical field of deformation prevention of the pressure vessel flaps. The method comprises the steps of 1, establishing a finite element model, designing an anti-deformation device, after the valve pieces are placed in the anti-deformation device, performinglocal mesh division on the flaps, and analyzing the stress of the valve pieces; step 2; carrying out optimization analysis on the outer surface constraint area of the flap; step 3; and performing optimization analysis on the constraint area of the inner surface of the flap. According to the method for weakening the deformation of the pressure vessel flap in the storage and transportation states,the pressure vessel petals are convenient to store and transport, and deformation is avoided.

Description

technical field [0001] The invention relates to the technical field of anti-deformation of pressure vessel flaps, in particular to a method for weakening the deformation of pressure vessel flaps during storage and transportation. Background technique [0002] With the development of petroleum, chemical industry, metallurgy and other industries, pressure vessels have been widely used in many fields. Container equipment has shown a trend of large-scale development in recent years, such as oil and gas storage tanks, nuclear power pressure vessels, etc. Large-scale container equipment helps manufacturing units increase output, reduce costs, and achieve economies of scale. Therefore, large-scale container equipment has broad application prospects. The overall processing and molding of many large-scale container equipment is difficult, requiring large-scale presses, molds and other equipment, and issues such as changes in wall thickness during the molding process and transportati...
