4.5A25 Hydrogen system brass safety release valve

Short Description:

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.

Hydrogen system brass safety release valve

The safety valve 4.5A25 is a special valve which is normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises beyond the specified value, the medium pressure in the pipeline or equipment can be prevented from exceeding the specified value by discharging the medium to the outside of the system. Safety valve is an automatic valve, which is mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Injection safety valve can only be used after pressure test.

The safety valve 4.5A25 plays a protective role in the generator hydrogen control system. When the system pressure exceeds the specified value, the safety valve will be opened to discharge part of the gas / fluid in the system into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system will not have accidents due to too high pressure.
