In this paper, on the basis of the existing hydrothermal sampling equipment has devised a new hydrothermal sampler. Using Ansys Workbench software to analyze the valve core and valve seat sealing, the valve core half cone Angle is obtained on the influence law of sealing performance. Cavity of hot fluid into the sampling moment of impact piston is analyzed, the analysis shows that the strength of the piston to meet requirements and the impact piston vibration does not affect the o-rings seal performance.
