Abstract

PURPOSE: To automatically eliminate the vibration of a steam valve, by adding a steam valve operating mechanism for minutely manipulating the steam valve by the signals of a system apart from an operating mechanism by means of a governor.
CONSTITUTION: When the output value of a vibroscope 4 exceeds a set point 6, the output of a comparator 5 enters a contact 14 while making it a condition that a push-button 9 for starting the control of vibration is depressed, and a steam regulating valve 1 is operated in the opening direction. When the steam regulating valve 1 is operated in the opening direction and an upper-limit limit switch is in ON, the contact 14 is OFF, the output of a limiter 8 stops the output of a pulse generator 15 and the variation of the valve lift of the steam regulating valve 1 is stopped. Meanwhile, the push-button 9 for starting the control of vibration is OFF when a push-button 10 for stopping the control of vibration is ON, and the steam regulating valve 1 stops at a fixed position.
