EASY-FIT HEAT SCREENING DEVICE FOR CONNECTING COOLING PIPE AND THROUGH-HOLE FORMED IN NOZZLE SUPPORT RING OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide an easy-fit heat screening device for connecting a cooling pipe 112 and a through-hole 114 formed in a nozzle support ring 116 of a gas turbine.;SOLUTION: This heat screening device is the type comprising a tubular structure 118 which has an outer diameter smaller than the diameter of the through-hole 114 and into which the cooling pipe 112 extends. The tubular structure body 118 has at the top a shaped annular end 126 which is inserted inside a groove 130 formed in the through-hole 114. The insertion is performed by bending the shaped annular end 126.;COPYRIGHT: (C)2004,JPO
