The Reheat Main Steam Valve is a type of control valve used in steam turbines, which is mainly used to control and regulate the steam flow in the reheat valve. The role of the reheat main valve in the steam turbine system is very important, it can ensure the accurate flow and pressure of the reheat steam, so as to ensure the normal operation and performance of the steam turbine.

10.3tThe reheat main steam valve is a multi-stage control valve, which is usually composed of a valve body, a valve core, a valve stem, a valve disc and other components. The valve body is the main shell of the valve, which is usually made of cast iron or steel with good strength and tightness. The valve core and the valve disc are installed inside the valve body, and the valve core is connected with the driving mechanism through the valve stem, which can realize the opening and closing of the valve.
The working principle of the reheat main steam valve is as follows: when the steam turbine is in operation, steam enters the main steam valve from the boiler, and after further heating through the reheater, the steam enters the reheat main steam valve. The position of the valve core and valve disc is controlled by the driving mechanism, which drives the valve core to rise or fall according to the signal of the control system, and adjusts the opening of the valve to control the flow and pressure of steam.
