Description

Special tool for disassembling high-pressure regulating valve and combining valve seats Technical Field The utility model relates to the technical field of high-pressure valve disassembling tools, in particular to a special tool for high-pressure valve adjusting disassembly and valve seat combination. Background The valve is a pipeline accessory for opening and closing a pipeline, controlling flow direction, adjusting and controlling parameters of a conveying medium, and the importance of the valve in the power industry of China is increasingly prominent along with the annual increase of the installed capacity of the gas turbine, so that the safe and stable operation of the gas turbine unit is a key for ensuring the healthy development of the power industry, and the gas turbine unit needs to be overhauled regularly in order to ensure the reliability of the gas turbine and the steam turbine. The valve core door rod of the existing main steam valve is an original inlet, and is pressed and disassembled by bolts or clamping pieces, so that the defects that damage can be caused by pressing by the bolts exist, and particularly the damage per se of the valve core and the door rod pressed by the bolts can be improved when the valve core and the door rod run for a long time under vibration and alternating load. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a special tool for disassembling a high-pressure regulating valve and combining a valve seat, which can realize the disassembly of a valve core and a valve rod and prevent the disassembly caused by the clamping of a bolt or a clamping piece. In order to solve the technical problems, the utility model adopts the following technical scheme that the special tool for disassembling the high-pressure regulating valve and combining the valve seat comprises: The bearing part is arranged on the supporting seat and is provided with a clamping cavity which is sleeved on the valve core and used for fixedly clamping the valve core; The twisting disassembly part is arranged on the bearing part and is provided with a fixing hole which is clamped and sleeved on the valve rod, and the twisting disassembly part is used for twisting the valve rod to disassemble the valve core and the valve rod; the valve core is clamped and fixed with the bearing part through heating expansion; the valve rod is clamped and fixed with the twisting disassembly part through heating expansion. Further, the bearing part is provided with a plurality of holes near the bottom. Further, the support base comprises a support plate and a groove for installing the bearing part. Further, the device also comprises a fixing seat for installing the supporting seat; the fixing seat is fixedly installed with the supporting plate through bolts.
