Control valve with displacement-compensating seal.

摘要

An apparatus for controlling the blowdown slurry from a wet oxidation reactor includes a pressure control valve (10) with a valve seat (44) and support assembly (46) which extends beyond the valve body (14) to prevent erosion by the blowdown slurry. The apparatus also includes a displacement-compensating seal (52-68) between the valve (10) and receiving vessel (38) to allow for thermal expansion and contraction during the blowdown cycle while maintaining the integrity of the seal.
