Spring force dismounting tool for pneumatic actuating mechanism of pneumatic valve

The utility model belongs to the technical field of key maintenance, and particularly relates to a spring force dismounting tool for a pneumatic actuating mechanism of a pneumatic valve, which comprises a connecting push rod, a thrust disc, a hollow hydraulic jack and a hand-operated hydraulic pump, the lower end of the connecting push rod is connected with a hand wheel rod of the pneumatic actuating mechanism; a hollow hydraulic jack is arranged between the upper cylinder cover and the thrust disc, and the connecting push rod penetrates through the hollow hydraulic jack; the side face of the hollow hydraulic jack is connected with a hand-operated hydraulic pump, and the hand-operated hydraulic pump pressurizes the hollow hydraulic jack. The technology replaces the traditional method for disassembling the spring force of the pneumatic actuating mechanism by using a long bolt; the tool is simple in structure, suitable for single-person operation and convenient to disassemble and assemble, and valve overhauling
