Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessel detection, in particular to a pressure vessel pressure resistance detection device. Background Art

[0002] As a closed device that can withstand a certain pressure, pressure vessels play an important role in industrial production. Their pressure resistance is directly related to their safety performance when used as storage carriers, and is directly related to the safe operation of the equipment and the safety of life and property of personnel. However, the existing pressure resistance test of pressure vessels cannot select the corresponding test mode according to the different adaptations of the pressure vessels. The traditional single method of injecting high-pressure gas into the interior for detection is inefficient and cannot quickly and directly simulate the effect of the container wall being subjected to high extrusion pressure or high extrusion pressure in a short period of time. The detection process is low in efficiency when the gas is injected into the interior, and the detection effect is poor. During the detection process, some equipment is difficult to accurately control the application and measurement of pressure, resulting in errors in the test results. The operating procedures of some detection equipment are cumbersome and require long-term training for professionals to master, which increases the detection cost and time.
