介绍 Summary

The SGF/C type accident pressure distribution valve is a multi channel plug-in reversing valve, which is used for the over speed protection system of hydroelectric generating sets in hydropower stations. When the speed is too high, the main pressure valve is closed, the governor refused to close the water guide mechanism of operation failure, SGF/C type emergency valve receives the overspeed protection signal and action, the governor main pressure valve is removed, the oil pressure in the oil system of the operation of relay device of water guide mechanism, emergency shut off water guide mechanism. To prevent over speed, to provide safe and reliable protection for the normal operation of hydroelectric generating units.
