Abstract

PURPOSE: To minimize vibration of a valve body, by selecting the size and shape of the valve body and its valve seat such that the steam flow can be rendered stable.
CONSTITUTION: A valve body 1 is shaped to have a convex spherical surface of a curvature R1 covering the portion where it comes into contact with a valve seat 4 and to have a concave spherical surface of a curvature r1 extending said contact part toward the top. Providing that the diameter of the valve body 1 at the point where it is held in contact with the valve seat 4 is D0 and the curvature of the valve seat 4 is R2, curvatures R1, r1 are so selected as to satisfy the following relationships, R1=(1.0W1.2) D0, r1=(0.4W0.5)D0 and R2=(0.1W0.2)D0. Since, with such an arrangement, steam is allowed to flow smoothly through the steam passage defined between the valve body 1 and valve seat 4, steam flow can be rendered stable.
