| 103 | The method of calibration system that is automatically controlled by a valve | JP19247989 | 1989-07-25 | JP2747526B2 | 1998-05-06 | EDOWAADO YUNGUUCHAN FUWANGU; CHIMOSHII DEIIN TOOMASU |
| In a method for automatically calibrating a controller for a governor valve controlled system the controller is placed in a calibration mode, then the valve settings are modified over a full range of operation. At predetermined levels of operation, the valve settings are maintained at preset values while system performance is measured. After the full range of valve operation has been covered, adjustments are made to make changes to valve characteristic curves corresponding to different modes of operation such as single valve and sequential valve modes. Other control parameters may be adjusted by evaluating system performance during normal operation. | ||||||

| PURPOSE:To prevent an adjusting valve from changing its valve lift, by providing a signal delaying device between an abnormality diagnostic device and a selector valve while a shut off valve, blocking the air pressure, between an air pressure control device and the selector valve, in the case of a control device of valve opening in the pneumatically operated adjusting valve. CONSTITUTION:A signal delaying device 41 is provided between an abnormality diagnostic device 17 and a selector valve 13, outputting a switching signal with a delay. While a shut off valve 40, being interposed between an air pressure control device 20 and the selector valve 13, is operated when the switching signal is received from the abnormality diagnostic device 17. Accordingly, an adjusting valve can be prevented from decreasing its valve lift by enabling pressurized air in a diaphragm chamber to be maintained. | ||||||

| PURPOSE:To correctly open and close a valve and supervise leakage with an acoustic sensor by providing a supervisory device with a densitometer for discriminating water from vapor and opening and closing a valve and supervising leakage on the basis of a decision signal and an acoustic sensor output. CONSTITUTION:An acoustic sensor 2 detects an acoustic signal generated when a fluid passes a valve 1, and an output signal is input to a preliminary processing circuit 4. After processings such as amplifying, removing noise and so on, the signal is input to a signal processing portion 6. A densitometer 3 and the processing device 5 examine whether a fluid flowing through the valve 1 is water or vapor, and an output signal is input to the processing device 5 to be compared with a preset value, thereby deciding whether the fluid is water or vapor. The decision signal is sent with an acoustic signal to the signal processing portion 6. The processing portion 6 is adapted to detect opening and closing of the valve 1 and a leakage condition on the basis of the scale of the acoustic signal and the decision signal indicating the kind of fluid. In this arrangement, even if a fluid is water or vapor, the opening and closing of the valve 1 and leakage condition can be detected with high accuracy. | ||||||
