Abstract
Official abstract text for this publication.
A handle 13 is formed in a hollow shape. A displacement sensor 4 is fixed to an inner surface of the handle 13 . The target 5 includes: a target body 22 which is arranged at a position away from a valve stem by a predetermined distance in the handle 13 ; a detection-use inclined surface 23 which is formed on a surface of the target body 22 which faces the displacement sensor 4 in an opposed manner; and a downwardly projecting portion 25 which projects downward from the target body 22 . A lower surface of the downwardly projecting portion 25 of the target 5 is received by a valve body 11 b so that the target 5 is rotated together with the handle 13 but is not upwardly and downwardly moved with respect to the valve body 11 b.
First claim
Opening claim text (preview).
The invention claimed is: 1. An opening degree detection device for a manual valve which is mounted on a manual valve where a fluid flow path formed in the inside of a valve body is opened or closed along with the rotational operation of a handle, wherein the opening degree detection device comprises a displacement sensor and a target having a detection surface which is made so as to face the displacement sensor in an opposed manner, and the displacement sensor, the target are arra…
