Beschreibung
Zusammenfassung:	The utility model provides a steam turbine lubricating oil temperature regulating valve control device. The steam turbine lubricating oil temperature regulating valve control device comprises a selector, a threshold comparator, a NOR gate, a PID module, an AND gate and a function converter. And the threshold comparator is respectively connected with the selector and the NOR gate. And the selector is sequentially connected with the PID module, the function converter and the AND gate. Wherein the selector is provided with three channels including a channel I, a channel II and a channel III. The output end of the threshold comparator is connected with the input end of the first channel of the selector, the input end of the third channel of the selector and the input end of the NOR gate. And the output end of the NOR gate is connected with the input end of the selector channel II. According to the technical scheme, the influence of temperature disturbance or valve overshoot on the valve can be avoided, and the pr
