The design of the generator hydrogen bellows globe valve KHWJ50F1.6P in the hydrogen circulation system is centered on sealing reliability. It adopts a double sealing structure of stainless steel valve body and metal bellows to effectively block the penetration of hydrogen molecules. The valve body material is made of 1Cr18Ni9Ti stainless steel that is resistant to hydrogen embrittlement and corrosion, and is matched with a hard alloy sealing surface to ensure long-term stability under high pressure and high temperature conditions. The bellows is precisely matched with the valve stem through a multi-layer welding process to achieve zero leakage sealing. At the same time, the anti-rotation structure design prevents the bellows from twisting and deforming, extending the service life. The structural design takes into account installation adaptability, and the socket welding interface is seamlessly connected with the standard pipeline to simplify the complexity of system integration.

 

During installation, the safety specifications of the hydrogen system must be strictly followed to ensure that the bellows globe valve KHWJ50F1.6P valve body is installed vertically and aligned with the pipeline axis to avoid tilting and causing sealing failure. Before installation, the strength test of the pressure-bearing components and the bellows leakage test must be completed to verify that each component meets the design requirements. During the connection process, external impact or over-tightening should be avoided to damage the sealing surface. After installation, an overall pressure test is required. It can only be put into operation after confirming that there is no leakage. To prevent impurities from entering, it is recommended to install a high-precision filter at the air inlet end and check the dynamic range of the valve stem and the bellows to ensure smooth opening and closing without jamming.

 

During the maintenance phase, it is necessary to strengthen the management of sealing performance, regularly check the appearance of the bellows of the stop valve KHWJ50F1.6P and the integrity of the valve body connection to avoid leakage caused by hydrogen corrosion or stress fatigue. During operation, the valve opening and closing frequency and action time should be monitored to avoid frequent operation exceeding the fatigue life of the bellows. When the system is shut down for maintenance, it is necessary to disassemble and clean the sealing surface and re-calibrate the pressure parameters to ensure that the valve continues to maintain zero leakage and stable control performance in the hydrogen circulation system, and to ensure the safe and efficient operation of the generator cooling system.
