Problems solved by technology

Sometimes the buildup of material becomes so pronounced that the plug 16 becomes completely stuck in one position or fails to open fully and the valve 10 fails to function properly
A lengthy operational shutdown and maintenance procedure must then be performed to clean the plug 16 and sleeve 20

Abstract

A process control valve comprises a. valve body having an inlet and an outlet and a plug. The plug selectively restricts fluid communication between the inlet and the outlet. The plug can have a plugbody and a plurality of fins extending radially outward from the plug body between a first end of the plug and a second end of the plug. Each one of the plurality of tins can have a tapered section proximate the second end of the plug. The tapered section can taper radially inward toward the second end of the plug.

Description

Background technique [0001] Process control valves are widely used in chemical processing plants. As shown in FIG. 1 , a conventional process control valve 10 operates to selectively allow fluid to flow between an inlet 12 and an outlet 14 along a flow path. The plug 16 opens or closes the valve 10 by axially translating within the guide sleeve 20 between the closed position and the open position. In the closed position, the head 18 of the plug 16 blocks the narrow bore 22 and engages the valve seat 26 to block the flow path, thereby preventing flow through the valve 10 . In the open position, the head 18 of the plug 16 is positioned away from the narrow bore 22 and the valve seat 26 . In the open position, fluid passes through the cylindrical channel 24 defining the narrow bore 22 and through the outlet 14 . The user pushes or pulls on the valve stem 28 to move the plug 16 axially within the sleeve 20 . [0002] The process control valve 10 is sometimes used to selectivel...
