Claims

[Scope of utility model registration request]

Main steam is transferred to the high pressure stage of the turbine through a main steam line equipped with a main steam stop valve and a main steam control valve, and low pressure steam is transferred to the turbine high pressure stage through a low pressure steam line provided with a low pressure steam stop valve and a low pressure steam control valve. In a mixed pressure turbine configured to lead to an intermediate stage of the turbine, both ends of a pipe in which a steam stop valve and a check valve are installed are connected to the main steam stop valve and the main steam control valve. and between the low-pressure steam stop valve and the low-pressure steam control valve, and the low-pressure steam bypasses the low-pressure steam control valve and flows from the low-pressure steam pipe side to the main steam pipe through the pipe line. A steam supply pipe for a mixed pressure turbine, characterized in that the steam flows to the roadside and is supplied to the mixed pressure turbine via a main steam control valve.
