Diagnostic system and diagnostic method for a valve, particularly a closing valve or a control valve
Patent number: 8429951Abstract: A diagnostic system and a diagnostic method for a valve, particularly a closing valve or a control valve, which is actuatable by a drive and is installed in a pipeline. Using a sensor, the pressures in the inlet side of the pipeline are detected and compared with a first reference value in an evaluation device while the valve is closed. The solid-borne sound level is measured using a sensor, and compared with a second reference value in the evaluation device. A signal for displaying leakage exceeding the allowable amount is output if the sound level exceeds the second reference value and if the pressure in the inlet side is smaller than or equal to the first reference value. A characteristic curve field is used to determine the first reference value of the pressure, the parameters thereof being the Kv value and the leakage class of the valve.Type: GrantFiled: September 23, 2008Date of Patent: April 30, 2013Assignee: Siemens AGInventor: Alf Püttmer -
Patent number: 8418528Abstract: An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter.
