Abstract

PURPOSE: To raise the durability of a valve by easing the concentration of stress on the valve for blocking the flow of a fluid by allowing the contact seat of a small- circular plug to touch with a circular seat of the inner hole of a seat ring.
CONSTITUTION: When the control part 12a of the plug 12 is inserted into the inner hole 13a of a seat ring 13, the plug 12 and the seat ring 13 contact with each other at P to block the flow of fluid. Since the contact P is biased toward the large-diameter direction of a contact seat face 12b, but not at the inflection point of the plug where stress concentration occurs most liably due to external or thermal stress, no breakdown occurs in the plug 12. Also, the flow characteristic of fluid can be made better because the control part 12a abruptly comes near the wall surface of the inner hole 13a when passing through a linear contact part P by making the radius r1 of circle on the plug 12 side small, and also the effect of preventing the breakage of the plug 12 can be raised.
