Valve opening or closing speed, and a pressure difference between valve opening and valve closing in various kinds of points along stroke are monitored by the micro processor 42, and a maintenance information is commanded when the valve opening rate is slid for a prescribed rate or more, for closing the valve in the case where the valve opening rate is excessively, in a prescribed stroke.

| 80 | POSITION INDICATOR FOR SUBMERGED VALVE | EP00948031.0 | 2000-07-27 | EP1209396A1 | 2002-05-29 | SANUDO TOFINO, José Luis; Bonnin Barcelo, Gerardo |
The position indicator is applicable to submerged valves forming part of hydraulic systems for the transfer of liquids or gas, based on that the corresponding signal which is obtained as a consequence of the state or position (open or closed) of the valve is transmitted by hydraulic pressure, from a long distance and transformed into an analog or digital signal which can be viewed on a display screen. The position of the valve (2) is set by the position of an actuator shaft (3') to which are secured cams (11) so that the rotation of the shaft causes the cams (11) to act on hydraulic cartridges (12), thereby regulating the position of said cartridges, and as a consequence, regulating the pressure of a secondary hydraulic system to provide said pressure signal which can be converted to any type of reliable indication, corresponding to the real position of the valve (2). |
