Device for detecting the operation of a valve
First Claim
1. Device for detecting the operation of a valve, comprising(a) a movable detection member connected to a movable part of said valve solid with a closure member of said valve and in direct contact with said movable part, so that said detection member and said movable part move simultaneously and proportionally;
- and(b) a displacement and position detector for monitoring the displacements and position of said detection member, said detector comprising at least one breakable part having a predetermined breaking point permitting the connection between said detection member and said movable part to be interrupted through the breaking of said breakable part in the event of jamming and blockage of said detection member.

Abstract
Device for detecting the operation of a valve, comprising a movable member (15) connected kinematically to a movable part (6) fastened to the closure member of the valve. A detector (24, 25, 26) makes it possible to monitor the displacements or the position of the detection member (15). The detection member (15) has at least one part provided with a predetermined breaking point (20). The kinematic connection between the valve and the detection member (15) can thus be interrupted by the breaking of the member (15) in the event of the jamming of the latter. The invention is in particular applicable to safety valves in nuclear power stations.
