Description
Technical field:
the utility model relates to the field of online operation valve positioners, in particular to an online operation valve debugging-free replacement positioner.
The background technology is as follows:
the positioner is a main accessory of the regulating valve, and is usually matched with the pneumatic regulating valve for use, and receives the output signal of the regulator, then uses the output signal to control the pneumatic regulating valve, after the regulating valve acts, the displacement of the valve rod is fed back to the positioner through a mechanical device, and the valve position state is transmitted to an upper system through an electric signal.
The positioner is a main accessory of the control valve, the valve rod displacement signal is used as an input feedback measurement signal, the controller output signal is used as a setting signal for comparison, when the valve rod displacement signal and the setting signal deviate, the output signal of the controller output signal to the actuating mechanism is changed, so that the actuating mechanism acts, and the one-to-one correspondence between the valve rod displacement multiple and the controller output signal is established. Therefore, the positioner constitutes a feedback control system with the valve stem displacement as a measurement signal and the controller output as a setting signal. The manipulated variable of the control system being the output signal of the positioner actuator
The most essential and common working principle of the localizer is basically the same in control rule, and the output signals are regulated after the input signals are compared with the position feedback signals. The object of the positioner control is the opening degree of the valve, the final expression form of the opening degree is that the feedback sensor of the valve position of the positioner detects the angle of the valve position, and the opening degree problem is converted into the angle problem, namely, the input signal of the positioner is related with the detection signal of the angle sensor of the positioner. The action process of the positioner is actually a closed-loop negative feedback regulation system. The key point of realizing online replacement and debugging-free of the positioner is to ensure that the angle characteristic of the newly replaced positioner is consistent with the angle characteristic of the positioner on the original valve.
In long-term industrial production, the positioner on the online operation valve is basically debugged integrally with the online valve after being replaced due to faults. In actual production, because some special conditions on site do not have the online debugging conditions of the valve positioner, the on-line debugging is needed to be stopped, and the working efficiency and the working production are affected.
The utility model comprises the following steps:
the utility model aims to provide a debugging-free replacement positioner for an online operation valve.
The utility model is implemented by the following technical scheme:
