Abstract
Official abstract text for this publication.
A switchbox for monitoring the position of a manual quarter-turn valve has a housing mountable to the valve to be monitored/controlled. A handle-driven shaft extends through the housing, with one end of the shaft couplable to the valve stem such that movement of the shaft moves the valve stem. One or more shaft position sensor switches interact with a cam on the shaft to signal shaft position and/or provide control signals. A plate coupled to the shaft articulates within a recess on the surface of the switchbox to limit motion of the valve to an operable range, such as between full ON and full OFF. The switchbox has a pair of lock tabs with lock apertures. A lock aperture in the plate is alignable with the lock tab apertures to receive a pin or padlock for locking the valve in a selected position. A potentiometer can be utilized in place of a switch as a shaft position sensor. The switchbox may be used with an original or new handle and may feature detents to allow a range of valve settings.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a manually operated valve having a body, a passageway through the body, an articulable member mounted to a valve stem and positioned within the passageway, the position of the articulable member determining the degree of openness of the passageway and an original handle attachable to the valve stem to facilitate turning the valve stem, comprises the steps of: (A) removing the original handle; (B) installing a switchbox on the valve,…
