Abstract

PURPOSE: To improve accuracy of initial flexion applied to a valve member in a valve device where the initial flexion is previously applied to the valve member consisting of many flexible plate materials, by forming the free end side of a divided flexible plate material to thicker dimension.
CONSTITUTION: A divided flexible plate material 34a" is formed in such length that its lower end is placed adjacently to an upper end 37 of a plate material 34a' further its upper end is situated almost in a same position as top ends of the other plate materials 34b, 34c. Thickness D1 of the plate material 34a" at the side of its free end 36 is larger than thickness D2 of the plate material 34a' at a base end side 35. In a seated face 38 of a seat body 32, a relief portion 39 is formed in a part at a face-to-face position to an end part of the plate material 34a". In this way, plate materials 34a, 34b in valve member 33 are warped by a difference between the thickness D1 of the plate material 34a" and the thickness D2 of the similar plate material 34a', that is, D1WD2, and applied with initial flexion. That is, the initial flexion can be decided only by the difference of plate thickness between the plate materials 34a' and 34a".
