 The safety valve 4.5A25 is used for the hydrogen control system of the generator. The function of the generator hydrogen cooling system is to cool the stator core and rotor of the generator, and carbon dioxide is used as the replacement medium. The generator hydrogen cooling system adopts a closed hydrogen circulation system, and hot hydrogen is cooled by cooling water through the hydrogen gas cooler of the generator. The hydrogen control system of the generator is used for hydrogen cooled steam turbine generators. The safety relief valve of the hydrogen supply device is a zero leakage safety valve used to ensure that the hydrogen pipeline system does not experience accidents due to high pressure on hydrogen equipment. Good sealing, high safety, and long service life.
