| Abstract: | An experimental device of semi spherical head large opening inner extruded nozzle,with design pressure 5MPa,opening ratio d i/D i=0.6,length of inner extruded nozzle 20mm,was buiet.By means of electric measuring method,at the experimental pressuree of 3MPa,3.5MPa and 4MPa etc.The experimental stress of connection zone between head and inner extruded nozzle was analized.The results show that the maximum stress is the circumferential tension stress at the connection zone between head and nozzle. |
