Abstract

PURPOSE: To provide sufficient sealing even for a large-sized valve or a valve for high pressures by forming contact faces opposed to the both ends of a valve body at the both ends of a valve axle transversely passing through a valve case, and supporting faces relatively in contact with the contact faces on the side of the valve case.
CONSTITUTION: In case of a butterfly valve, through holes 2, 3 at right angles to the axis of a valve case 1 is made on the both sides of it, with bearing metals 4, 5 plugged inside respectively. A valve axle 14 on which a disc valve body 7 is unitedly mounted is supported by the bearing metals 4, 5 and a drive is connected to a driving end 8 of the valve axle 6. Contact faces 15, 16 opposed to the both ends of the valve body 7 are formed by tapering partial areas of the valve axle 14. For positioning the valve shaft 14 or the valve body 7 with respect to the valve case 1, supporting faces 19, 20 on the side of the valve body 7 of end walls 17, 18 attached to the valve case 1 are fit to the contact faces 15, 16.
