Abstract

Abstract: From two aspects of the faults of thermal electrical signals or electro hydraulic converter and the mechanical jam of valve spindle, the reasons of jam fault of the highpressure main stop valve in a 300MW steam turbine were analyzed. The solution and preventive measures were put forward.
