摘要： It is the objective of the present invention to enable smooth rotation of the grid plate and normal operation of the bypass valve, regardless of the operational state of the gas turbine. The bypass valve according to the present invention is provided with a frame, which is disposed to cover a plurality of compressed air introduction ports that are arrayed in ring, and in which there are formed a plurality of first openings that communicate with a combustion chamber tail pipe; a grid plate which has a ring shape identical to that formed by the plurality of combustion chamber tail pipes and in which there are formed a plurality of second openings that are positioned opposite the first openings, this grid plate being supported in a manner to enable rotation in its circumferential direction; an inner rail and an outer rail that are provided to the inside surface and the outside surface of the grid plate and are formed in a unitary manner with the frame; and a plurality of guide rollers that are provided to the grid plate, and that come into contact with either the inner rail or the outer rail depending on the circumstances and assist in the rotation of the grid plate.
