Gaps in valves between the stems and boxes are a source of rather large steam and heat losses in power-generating steam turbines. A unique development of specialists employed by the Vserossiiskii Teplotekhnicheskii Institut — superairtight seals (SAS) with composite materials, which permit reliable sealing of valves with minimal friction within the system—is presented. Investigations conducted have indicated that the proposed type of SAS is capable of sealing gaps in valves with steam parameters of 29.75 MPa (300 kgf/cm2) and 600°C. [ABSTRACT FROM AUTHOR] |
