| description | The utility model relates to a lifting device for the lifting height of a valve rod of a safety valve. The lifting device comprises a lifting fastening piece, a support piece and at least three support columns, wherein the lifting fastening piece is matched with the upper end of the valve rod of the to-be-tested safety valve; the support piece comprises a guide hole and a propping surface, wherein the guide hole is provided for the valve rod of the to-be-tested safety valve to be inserted, and the propping surface is arranged at the upper side of the support piece and is propped against the lifting fastening piece. The support columns are supported between the valve body of the to-be-tested safety valve and the support piece, so as to form a triangular support to the support piece and keep the guide hole axially vertical to a horizontal plane. According to the lifting device, the valve rod is lifted by a mechanical method, and the structure is simple and practical, therefore the lifting height of the valve ro |
