ール弁における弁座押圧装置。[Claims for Utility Model Registration] A trapezoidal tooth row is provided on the inner end of the liquid flow path of a top entry type ball valve, which is fixedly fitted in a non-rotatable manner and has a continuous convex surface, inclined surface, and concave surface on the inner end surface. a fixed ring, and a trapezoid that fits into the fixed ring and the liquid flow path from the inside and that can mesh with the trapezoidal tooth row of the fixed ring at any position on the outer surface of the flange facing the fixed ring on the flange connected to the inner end. When the pressing cylinder provided with a tooth row and the convex surfaces of both tooth rows are overlapped, it becomes a rotation stopper of the pressing cylinder that can be inserted into the gap hole formed by the concave surface and the inclined surface of both tooth rows, and both After meshing the tooth rows and assembling the ball and valve seat into the valve case, rotate the press cylinder and bring the convex surfaces of both tooth rows into contact with each other, thereby pressing the valve seat against the ball with appropriate pressure. A valve seat pressing device for a top entry type ball valve, in which a rotation stopper is inserted into a gap hole between concave surfaces.
