To improve the reliability of deep-sea hydrothermal sampler, a new type hydrothermal sampler controlled by hydraulic valve was introduced. A high-temperature high-pressure water hydraulic solenoid valve was adopted in the flow control part of the hydrothermal sampler. The key technologies of the water hydraulic valve involved the aspect of seal, lubrication structure, cavitations resistance and materials. The mechanical structure of the deep-sea electro-magnet and the deep-sea solenoid valve were designed to fit the high temperature and high pressure operation environment. The detailed operational process of the hydrothermal sampler was described. The experiment results show that compared with the valve driven by a step motor, the deep sea solenoid valve is more reliable because of its simplified mechanical structure. The hydrothermal sampler is suitable for the deep-sea exploration.
