Abstract
PURPOSE: To effectively prevent leakage of a high-pressure fluid by such arrangement that, of the dimensions of the gap between the rotary support shaft of a valve body and a bearing portion which is on the side of a valve box and fitted around the shaft, the dimension in the flow direction (under the condition where the valve body is in the closing position) is reduced.
CONSTITUTION: In a rotary valve, a rotary support shaft 4 in connection with a valve body 3 is supported in a valve box 2 through a bearing portion 5, and the valve body 3 is added on its periphery with a metal seat 7 opposed to a tapered metal seat 6 arranged on the inside peripheral portion of the box 2. A shaft hole 22 of the bearing portion 5 including a bush 13 for bearing the shaft 4 is elliptic in cross section, while the shaft 4 is circular in cross section. Of the dimensions of the gap S between the shaft 4 and the bearing portion 5, the dimension in the direction toward the seat 6 (under the condition where the valve body 3 is in the closing position) is set larger than that in the direction perpendicular to the former direction. By this, creation of gap between the seats 6 and 7 on valve opening can be avoided.
