| Abstract: | According to GB 50251-2003 ＂Design Requirements of Gas Transmission Pipeline Engineering＂, the analysis focuses on the gas-liquid linkage execution structure of route shut-off valves of SHEFER in America and LEDEEN in Italy. And then some problems of route shut-off valves in the real application are discussed based on the practical measurement data and simulated data. Finally some measures of solution and precaution are proposed, which are to take advantage of the present technologies. |
