Filed: 1983-07-27
Abstract: PURPOSE:To keep off any vibration in a valve plug, by installing an annular groove in the upside of an upper side valve seating part, while making up an inner through hole piercing into the inside of the plug from the side of this groove. CONSTITUTION:On an outer circumferential surface of a valve plug 6, and annular groove 21 is installed in the upside of an upper side valve seating part 8. An inner through hole 23 piercing into the inside of the valve plug 6 from the side of the annular groove 21 is made up in one side of a peripheral wall 24 of the valve plug 6. Part of a flow B running inside the valve plug 6 from a through hole 10 flows into a clearance 26 after passing through the inner through hole 23 by means of a pressure differential produced inside the valve plug 6 and the clearance 26. With this constitution, the pressure differential is produced in and around the valve plug 6 which is therefore made to act on one direction. Accordingly, any vibration in the valve plug 6 inside a cage 1 is thus preventable.
