Definitions
- the invention relates to an open / close valve actuator comprising a pneumatic actuator which is ventilated or vented in response to the presence or absence of a control voltage that is available from a control system and moves the valve to a safety position when vented to an operating position and vented. and with an electro-pneumatic positioner, which moves the valve briefly to a desired position over a part of its travel to perform a partial stroke test, while the actual position of the valve detected and as a function of the actual position and the target position generates a pneumatic manipulated variable for the pneumatic drive.
- ESD emergency shut down
- a solenoid valve which is controlled by a control voltage supplied by a control system, connects the pneumatic drive to a compressed air supply. In an emergency, the control voltage is switched off in order to vent the pneumatic drive via the solenoid valve, so that the valve is moved from the operating position to the safety position.
- an additional positioner is mounted on the pneumatic drive.
- the valve In the partial stroke test, the valve is moved from the operating position over part of its travel by means of the positioner and then returned again. emotional. The position change is so small that the ongoing operation of the system in which the control valve is installed, must not be interrupted and is only slightly disturbed.
- the positioning motion is detected and stored.
- the positioner is mounted next to the solenoid valve as a further unit with corresponding wiring and piping to the fitting consisting of valve and actuator.
- an analog output module must be provided in the control system for the control of the positioner, the z. B. provides a 4-20 mA signal to transmit the setpoint for the valve control. This is a great additional expense both materially and financially.
- the solenoid valve requires a further test procedure.
- the problem is solved in that in the adjusting device of the type specified the positioner is connected to the power supply side of the control system available voltage and is designed to vent the pneumatic drive in case of power failure, and that in the positioner Routine for performing the partial stroke test and a value for the desired position of the valve are stored in the operating position.
- the solenoid valve completely eliminated, the positioner takes over its function.
- the positioner carries out the partial stroke test autonomously in order to detect a stiffness or blockage of the valve at an early stage. In this case, the positioner does not require a setpoint specification, for example in the form of a 4-20 mA signal, so that in this case the control system no longer requires an expensive analog output module.
- the value for the desired position of the valve is stored in its operating position in the positioner (programmed).
- This setpoint is preferably smaller by a small amount than the end stop of the valve in the operating position and is z. B. 97% of the end stop.
- the positioner will attempt to regulate the valve position to meet the setpoint until a partial stroke test is requested or, in an emergency, the pneumatic actuator is vented to move the valve to the safety position.
- known diagnostic functions of the positioner such as the monitoring of the pneumatic leakage or the stiffness of the valve can be used, whereby the safety is further increased, because the permanent Ausregelvorrud permanently with the partial Stroke test comparable test is done in the small signal range.
- the positioner is supplied with the same control voltage, usually a 24 V signal, which is at the state of the
- the positioner is therefore a complete replacement for this solenoid valve.
- the solenoid valve does.
- the positioner is required, which at the same time assumes the solenoid valve function. This simplifies the piping as well as the attachment to the valve, because only one unit to grow and connect.
- the cable originally required for the solenoid valve and the power supply for it can be reused for the positioner.
- the partial stroke test can be performed manually via a control element on the positioner, by a binary signal, the z. B. is sent from the control system via a digital output to a binary input of the positioner, or automatically triggered by the positioner at regular intervals by a timer contained in the positioner.
- the partial stroke test can also be started via a HART command (4-20 mA) from the control system, but this would require an analog output module there.
- the evaluation of the partial stroke test can be carried out independently by the positioner, wherein the actual positions of the valve recorded during the partial stroke test are stored in a memory of the positioner for diagnostic purposes.
- the curve of the actual positions can then z. B. locally via a notebook with z. B. PDM (Process Device Manager) read and compared with a reference curve.
- the test result can be reported via a preferably binary signal output to the control system.
- the message of the actual position reached in the partial stroke test can also be reported via a position detector with contacts or in the form of a proximity switch (eg slot initiator).
- the feedback can be sent to the control system via the communication interfaces.
- the test result can also be displayed on a display of the positioner.
- the availability of the adjusting device according to the invention can be further improved in an advantageous manner by connecting a pressure monitor arranged in the compressed air supply for the positioner with a signal input of the positioner and that the positioner is designed to adjust the regulation when a pressure falls below a minimum pressure to shut off the ventilation of the pneumatic drive.
- a pressure monitor arranged in the compressed air supply for the positioner with a signal input of the positioner and that the positioner is designed to adjust the regulation when a pressure falls below a minimum pressure to shut off the ventilation of the pneumatic drive.
- Position limit indicator for reporting a deviating from the operating position actual position of the valve are connected to a signal input of the positioner and the positioner to be configured to adjust when exceeding the position deviation, the control and shut off the ventilation of the pneumatic actuator.
- the pneumatic output valves of the positioner are closed so that the positioner no longer tries in vain to readjust the valve position, but instead locks the existing compressed air in the pneumatic drive and thus releases a white - tere change position of the valve away from the operating position prevents.
- Figure 2 shows an embodiment of the adjusting device according to the invention.
- the adjusting device according to the prior art shown in Figure 1 has an open / close valve 1, by means of a pneumatic actuator 2 via an actuating element 3, here in the form of a lifting rod, either in an operating position, for. B. “on”, or a security position, eg. B. "to”, can be brought.
- a solenoid valve 4 which is controlled by a control voltage V s supplied by a control system 5, connects the pneumatic drive 2 to a compressed air supply 6.
- V s supplied by a control system 5
- the control voltage V s is switched off in order to vent the pneumatic drive 2 via the solenoid valve 4 ,
- the pneumatic actuator 2 is then depressurized and moves the actuator 3 with the valve 1, for example, under the action of a spring 7, from the operating position to the safety position.
- an additional positioner 8 is pneumatically connected between the solenoid valve 3 and the compressed air supply 6.
- a position sensor 9 detects the actual position of the valve 1 on the control element 3 and feeds it to the positioner 8, which sets a variable output pressure as a control variable as a function of the actual position and a predefinable desired position Drive 2 to move the valve 1 in the desired position.
- the positioner 8 via a communication link 10, z. A 4-20 mA line, with an analogue output module 11 of the control system 5 connected.
- the valve 1 is moved by means of the positioner 8 from the operating position over part of its travel and then moved back again. The position change is so low that the current
- the illustrated in Figure 2 embodiment of the adjusting device according to the invention differs from the device shown in Figure 1 according to the prior art, characterized in that the positioner 8 also takes over the function of the here dropped solenoid valve and is connected without interposition of the solenoid valve with the pneumatic drive 2.
- the value s so n for the desired position of the valve 1 in its operating position is stored in the positioner 8, so that no setpoint input by the control system 5 is required.
- the positioner 8 is fed by the control system 5 with the control voltage V s . If the control voltage V s fails or is switched off, the positioner 8 vents the pneumatic drive 2 via its pneumatic output stage 13, so that the valve 1 moves into the safety position.
- the positioner 8 then terminates its control function and blocks instead the ventilation of the pneumatic drive 2 from.
- a position limit indicator 16 can be provided, which signals the position controller 8 via the signal input 15 when the actual position of the valve 1, too much so s n deviates from the target value.
- the partial stroke test can optionally be triggered manually via a control element 17, by a binary signal at a signal input 18 of the positioner 8 or at regular intervals by a timer 19 contained in the positioner 8.
