The common regulating valve regulating mechanism of the steam turbine adopts a valve rod lifting mode to sequentially lift each valve core to regulate load. The valve rod is communicated with a steam chamber of the steam turbine, and in order to prevent steam from leaking outwards from a gap between the valve rod and the valve cover, the valve rod and the valve cover are sealed by using packing, and most of the existing valve rod sealing packing adopts graphite which is stable in chemical property, corrosion-resistant and high and low temperature resistant. When the unit is operated for a long time, the graphite packing is worn by load adjustment, and finally steam leakage occurs. Consequently must carry out the packing and change, but because the intracavity is high-pressure steam, pressure is big, and the temperature is high, and the filler overall length is 180mm, uses ordinary graphite to take out the instrument and can't take out fast, leads to the maintenance time to increase, and operating personnel has great risk of being scalded by the steam in the in-process of taking out graphite moreover.
