弁の弁座装置。In a butterfly valve, a disc-shaped main valve, in which a pole-shaped sub-valve with a water passage hole fits into the center, is rotatably supported in a valve box by both valve shafts. A vertical sub-valve drive shaft is fixed at the upper center of the sub-valve having a water passage hole, and within the central hole of the main valve, a small amount of shaft is attached to the outer periphery of both sides of the sub-valve in the horizontal direction. A valve seat device for a sub-valve, characterized in that ring-shaped valve seats on both sides that can make spherical contact within a certain range are loosely fitted so that they can move slightly in the water flow direction.
