Abstract
PURPOSE: To improve sealingness of a valve, by disposing a spherical valve element at a position facing a nozzle connected to the process line for processing gas containing dust of nuclear fuel or the like, in the manner that centering of them can be achieved automatically.
CONSTITUTION: Nozzle 3 connected to process line L is fixed in a hole 2 formed in the upper end of casing 1, and passage 21 is formed at the bottom 1a of casing 1. Valve seat member 9 is mounted on guide rail 7 such that it can be moved vertically toward and away from opening 30 of said nozzle 3. Upwardly of the valve seat member 9, valve element 16 is provided in the manner that its spherical surface 17 faces the opening 30. Cleaning means 20 is inserted into casing 1 through hatch 4, and cover 19 is applied over the valve element 16 and valve seat member 9 for prohibiting intrusion of dust of nuclear fuel contained in gas introduced from nozzle 3. Valve element 16 is urged upward into tight contact with opening 30 by the drive of actuator rod 10a, and in doing so it is centered automatically to the nozzle 3, so that it is enabled to tightly close the opening 30.
