The unloading device was used in the manual high-pressure cut-off valve to reduce the operating hand moment. However, the existing unloading device has the problems such as the poor unloading efficiency, or the hard manual operation. In this paper, a kind of unloading device was offered to solve the mentioned problems. The function principle of the unloading device was offered and a kind of optimization design method was applied to have reasonable matching parameters of the unloading device. The cut-off valve applying the unloading device was verified to have a more reliable performance and flexible operation.
