Abstract

PURPOSE: To eliminate bending moment by providing a ballance piston above the neck of each valve while interlocking between upper section of cylinder formed on valve chamber lid to contain the ballance piston and the post-valve through a piping.
CONSTITUTION: A ballance piston 12 having piston rings 9 is arranged on the top of neck 6 of a valve 2. Said piston 12 is contained slidably in the cylinder 8 formed in the valve chamber lid 1 and the piston rings 9 maintain air-tight between them. Down-stream section of a valve seat engaging with the valve 2 or the post-valve 10 is connected with the top of the cylinder 8 through a piping 11. Here the diameter t1 of ballance piston is same or slightly smaller than diameter t2 of the valve seat. Consequently the pressure at the post-valve 10 is the same with that of above the cylinder 8, thereby the steam force of the valve 2 is eliminated for any load variation. In result, no bending moment is produced on a valve lifting rod 3.
