Method for monitoring a pipeline and position regulator for a control valve
The invention relates to a method for monitoring a pipeline in order to detect the slow reduction of the free inner cross-section by means of the position of a control valve in the pipeline. When the flow rate is essentially constant, a first position is determined and stored at a first moment. Acco...

| description | The invention relates to a method for monitoring a pipeline in order to detect the slow reduction of the free inner cross-section by means of the position of a control valve in the pipeline. When the flow rate is essentially constant, a first position is determined and stored at a first moment. According to at least one second position of the control valve, determined at a second, subsequent moment, the point at which the position of the valve exceeds a pre-deterrninable threshold value for a valve opening is determined, and optionally a signal is emitted to indicate that the threshold value has been exceeded and/or the time at which it was exceeded. As a result, suitable maintenance measures can be introduced, before faults occur in the process system. |
