Continue to Section 3, the motor in this product can be connected to the rotor through a transmission device, especially a multi-stage transmission device. The electromechanical actuator is provided with an oil reservoir, and the electromagnetic clutch is connected to a damping device, wherein the damping device is at least partially immersed in the oil reservoir, and the damping device may be a damping disc connected to a cylindrical element, or a preferred implementation In the example, the cylindrical element itself forms a damping device. In particular, the outer surface of the cylindrical element is at least partially immersed in the oil reservoir. A damping disc or a cylindrical element may be provided with an element such as a fin on its outer circumference to increase the damping coefficient. Preferably, the motor and the crank disc are provided outside the oil reservoir, which is preferably provided with non-pressure-bearing oil, and the damping device provides a damping, which is particularly useful for protecting the valve seat from injuries in the event of the valve closing suddenly. advantageous. Because of this damping, even in the case of a valve closing suddenly, the valve piston will reduce the operating speed near the valve seat before touching the valve seat.
According to another technical feature of the product, the electromechanical actuator includes a rocker arm, one side of the rocker arm is connected to the push rod, and the other side can be connected to the valve piston. The use of the rocker arm can save the space for the actuator and the valve. In addition, by selecting rocker rods with different arm lengths, the valve piston can be overcome by applying a small force on the corresponding rocker rod through the actuator. The valve spring moves with a large spring force, which is generated by the valve spring being compressed.
Another technical feature of this product. The electromechanical actuator is connected to a valve provided with a valve piston. Due to the force of the valve spring, the valve is in the closed position, and the valve can be opened against the spring force of the valve spring. The valve is preferably a turbine valve, especially steam Turbine valve, the actuator connected to the valve is effective for both normal operation and sudden interruption of turbine steam supply, said normal operation means closing and opening the valve to regulate steam flow during normal operation of the turbine. In order to meet the technical requirements, we provide a turbine, in particular a steam turbine provided with a valve for regulating the flow of a fluid. The valve is provided with a valve piston and is connected with the electromechanical actuator.
In the embodiment shown and described, the product includes: an electromagnetic radiating plate clutch, an electromechanical actuator for a valve having a valve piston, an electric motor, and an electromagnetic radiating plate clutch especially for a steam turbine , And a turbine, especially a steam turbine. However, this does not mean that the product is limited to the embodiment shown, because various improved structural changes can be made to the product, but not beyond the essence of the product.
