High-pressure bursting test system for pressure vessels

Abstract

The invention discloses a high-pressure bursting test system for pressure vessels. The high-pressure bursting test system comprises a high-pressure bursting sample vessel, a high-pressure power source module, a vessel installing and sealing protection device module, a pressure relief device module, and a pressure / flow signal measuring and displaying module, wherein the high-pressure power source module is hermetically connected with the high-pressure bursting sample vessel by the vessel installing and sealing protection device module, the pressure / flow signal measuring and displaying module is arranged on an airflow path / liquid flow path of the high-pressure power source module, and the pressure relief device module is connected between the high-pressure power source module and the high-pressure bursting sample vessel. By using the high-pressure bursting test system for pressure vessels disclosed by the invention, a pressure-liquid feed amount change curve can be measured and recorded in real time, and through analysis on the curve, the volume expansibility, yield pressure, ultimate load, bursting pressure and safety margin of the vessel can be obtained; and the high-pressure bursting test system is high in measurement accuracy and comprehensive in data and can provide more useful information for scientific researches.

Description

technical field [0001] The invention relates to the field of testing, in particular to a pressure and flow testing system, in particular to a pressure vessel high-pressure burst testing system. Background technique [0002] The blasting experiment of the pressure vessel is very necessary to study the whole process of the pressure vessel from elastic deformation to plastic deformation to final failure, to understand its failure mode, and to verify the theoretical calculation. [0003] For safety reasons, small container blasting experiment techniques with low blasting energy are generally used in laboratories. [0004] Usually, most of the blasting experimental devices only record the change of pressure, and finally record the burst pressure of the container, but the parameters of the deformation of the reaction container, such as the radial displacement of the container or the liquid inflow of the container, are not recorded, let alone real-time information. Therefore, it c...

[0004] Usually, most of the blasting experimental devices only record the change of pressure, and finally record the burst pressure of the container, but the parameters of the deformation of the reaction container, such as the radial displacement of the container or the liquid inflow of the container, are not recorded, let alone real-time information. The change of the outlet pressure-inlet volume curve, so it cannot reflect the whole process of the container from elastic deformation to plastic deformation to burst failure
