Abstract

The invention relates to a lower sealing valve overhauling tool and method, and belongs to the field of blast furnace equipment. The overhauling tool comprises a frame body, an overhauling unit is arranged at the front end of the frame body and comprises an arc-shaped supporting plate and a panel, the arc-shaped supporting plate is vertically connected to the front end of the frame body, and the panel is horizontally connected to the arc-shaped supporting plate and the upper end of the frame body. The panel covers the partial area of the upper end of the frame body. Supporting arms are connected to the arc-shaped supporting plate, the number and distribution of the supporting arms are matched with those of valve plate replacing holes in a valve plate of a lower sealing valve, valve plate replacing shafts are arranged at the front ends of the supporting arms and used for being inserted into the valve plate replacing holes, check rings are installed on the valve plate replacing shafts, and through holes are formed in the ends of the valve plate replacing shafts and used for installing cotter pins. Bolt holes corresponding to threaded holes in a valve seat are formed in the panel. The overhauling tool has the two functions of dismounting and mounting the valve seat and the valve plate at the same time, solves the problems of overhauling and replacement of the valve seat and the valve plate, enables operation to be standardized, improves working efficiency, and provides safety guarantee for overhauling personnel.

Description

technical field [0001] The invention belongs to the field of blast furnace equipment and relates to a maintenance tool and a maintenance method for a lower sealing valve. Background technique [0002] The modern large-scale blast furnace charging system basically uses a bellless top charging system, and the lower sealing valve is one of the important equipment of the blast furnace bellless top charging system. [0003] During use, due to the harsh working environment of the lower sealing valve, the valve seat and valve plate of the lower sealing valve are parts that are relatively easy to wear and tear. During use, they need to be disassembled for repair and then restored or directly replaced with new spare parts. Prior to this, maintenance or replacement of valve seats and valve plates generally required maintenance personnel to use temporary spreaders and other tools to complete the relevant work according to the site conditions. The maintenance work was not standardized, ...
