The bellows stop valve WJ10F-1.6P achieves high sealing performance and zero leakage through its special dual sealing structure. This is also one of the reasons why it can be used in the hydrogen cooling system of generators.

The hydrogen cooling system of the generator is a special cooling system, and the main reasons for using bellows shut-off valves WJ10F-1.6P in its pipelines are as follows:

• 1. High pressure sealing performance: As a high-pressure medium, hydrogen usually has a high working pressure in the cooling system of the generator. The shut-off valve WJ10F-1.6P has good high-pressure sealing performance and can effectively prevent hydrogen leakage.
• 2. Thermal expansion compensation: The bellows structure of the bellows stop valve WJ10F-1.6P has a certain degree of elasticity and compressibility, which can compensate for the deformation and displacement of the pipeline during the thermal expansion process. In high-temperature and high-pressure environments, the pipelines in the generator cooling system will undergo certain deformation and displacement due to thermal expansion. The use of bellows shut-off valves can reduce the stress and damage caused by the influence of thermal expansion on the pipelines.
• 3. Vibration absorption: During the operation of the generator, it will be subjected to certain vibrations and impacts, which will also have an impact on the pipes of the cooling system. The corrugated structure of the bellows globe valve WJ10F-1.6P can absorb and slow down the vibration and impact of the pipeline, reduce damage to the pipeline and valve, and improve the reliability and durability of the equipment.
• 4. Ultra low temperature adaptability: The hydrogen gas in the generator hydrogen cooling system is usually in a low-temperature state, and may even reach ultra-low temperatures. The bellows shut-off valve WJ10F-1.6P can still maintain good sealing performance and flexibility in low-temperature environments, adapt to the requirements of low-temperature environments, and effectively prevent leakage of cooling media.

It can be seen that the use of bellows globe valves in the hydrogen cooling system of generators is mainly to meet special needs such as high-pressure sealing performance, thermal expansion compensation, vibration absorption, and ultra-low temperature adaptability. This can ensure the stable operation of the cooling system and effectively protect the safety of the equipment.
