A double position radial fracture test system for a safety break valve used in petrochemical industry

Abstract

A kind of double position radial fracture test system of safety pull-off valve for petrochemical industry, the middle part of the upper end of the chassis is provided with high-frequency high-pressure pulse air gun moving along the upper end between right end support assembly and left end support assembly, left end support assembly is connected with pressure increasing device, the shooting port of high-resolution image measurement and simulation optimization analysis system moves along the upper end between right end support assembly and left end support assembly, and safety pull-off valve to be measured is arranged between the upper end of right end support assembly and left end support assembly.The main advantages are: high-precision, high-resolution full-strain or instantaneous deformation fracture measurement is realized, the instantaneous shear fracture process of safety pull-off valve under sudden dragging process is accurately and effectively simulated and measured, the degree of automation is high, the measurement and analysis precision is high, the detection timeliness and accuracy are improved, the detection cost is reduced, and the product safety and quality are improved.
