IPC: F03C1/38
Filed: 2003-12-01
Abstract: <P>PROBLEM TO BE SOLVED: To allow a sealing member enclosed in a pressure chamber of a rotary valve of a rotating fluid machine, to exhibit sufficient sealing function even when the pressure chamber has low pressure.  <P>SOLUTION: The pressure chamber 84 into which high-temperature and high-pressure steam is introduced, is opened to a mating surface 83 of a valve body part 72 of the rotary valve 71 with a fixed side valve plate 73. A leakage of steam to the mating surface 83 is prevented by a V-packing 88 enclosed in the pressure chamber 84, and the fixed side valve plate 73 and a movable side valve plate 74 are brought into close contact at a sliding surface 77 by the pressure applied to the pressure chamber 84. The V-packing 88 is pressed at least to the radial outside by a backup ring 90 provided at the back face of the V-packing 88. Consequently, even when it is hard for the V-packing 88 to exhibit the sealing function because the pressure chamber 84 is in a low pressure state, a seal lip S2 of the V-packing 88 is pressed to the inner peripheral surface 84a of the pressure chamber 84 by the pressing force of the backup ring 90 to secure the sealing function. The leakage of the high-temperature and high-pressure steam can thereby be prevented.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
