4.5A25 Hydrogen system brass safety release valve
The safety valve 4.5A25 is used in the generator hydrogen control system, which is used for hydrogen cooling steam turbine 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. The hot hydrogen is cooled by cooling water through the hydrogen cooler of the generator. The safety relief valve of the hydrogen supply device is a zero leakage safety valve, It is used for hydrogen equipment to ensure that the hydrogen pipeline system will not have accidents due to high pressure. Good sealing, high safety and long service life. -
YSF series pressure relief valve for transformer
YSF series relief valve is a pressure relief device developed by our company, which is used to protect the safe operation of the oil tank and can monitor the pressure change inside the oil tank in real time. It is mainly used in oil-immersed power transformers, power capacitors, reactors, etc. On power equipment, it can also be used to release the pressure when the oil tank of the on-load switch is over pressured. -
DN80 Sealing oil vacuum tank floating valve
DN80 floating valve uses mechanical ball-float liquid-level controller. It uses automatic oil- tank or other containers to supply the oil, so that the oil tank is kept within the liquid-level range. It is mainly used in the single-circuit oil sealing control system vacuum oil-tank of the hydrogen cooling turbo-generator for liquid-level control. It also can be used in the oil-tank supply or the water-tank supply. -
FY-40 floating valve of Generator seal oil float tank
FY-40 floating valve uses the actuator of the ball-float lever to control the conical needle plug installed in the valve plug According to the hydraulic amplification principle, the valve plug is opened to drain the oil as the needle plug moves, in order to control the liquid-level in the oil tank. The valve system is mainly used to control the liquid-level of the sealing oil tank in the turbo generator, so that the oil is kept in the liquid-level range. It can also be used in the oil-drain valve of the single circuit seal oil tank
