Abstract
The invention discloses an intelligent valve positioner which comprises an intelligent controller, an electric control valve, an actuator and a valve position sensor. The actuator is a pneumatic actuator. The valve position sensor is a split non-contact sensor, a valve is installed on the actuator, the electric control valve is used for receiving order signals sent by the intelligent controller, the actuator is used for receiving the order signals sent by the electric control valve, and the valve position sensor is used for transmitting detected practical valve position signals to the intelligent controller. The intelligent valve positioner is simple in structure, reasonable in design, high in control precision, and suitable for severe environments, and the split non-contact sensor is good in heat-resistance effect.
Description
Technical field
The present invention relates to a kind of intelligent valve positioner.
Background technique
At present, the general adoption rate valve of the core component of known intelligent valve positioner and nozzle baffle type equilibrium valve.Proportional valve generally comprises a main valve body and adds a pilot valve, the spool of pilot valve inside is made with certain taper, then with integrated displacement monitor, drive unit, control instantaneous flow, reach the object of indirect control main valve flow, its complex structure, requirement on machining accuracy is high, and cost of production is high, expensive, its applied environment is comparatively harsh; Nozzle baffle type equilibrium valve adopts mechanical torque balanced controls, and component of machine quantity is many, maintenance and maintenance inconvenience.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, a kind of intelligent valve positioner is provided, simple in structure, reasonable in design, control accuracy is high.
For achieving the above object, technological scheme of the present invention has been to provide a kind of intelligent valve positioner, comprise intelligent controller, electrically-controlled valve, actuator, valve position sensor, described actuator is pneumatic actuator, described valve position sensor is split noncontacting proximity sensor, valve installation is in actuator, electrically-controlled valve is for receiving the command signal that intelligent controller sends, actuator is for receiving the command signal that electrically-controlled valve is sent, valve position sensor is transferred to intelligent controller by the actual valve position signal detecting, described intelligent controller is accepted the duty setting signal of 4-20mA, the actual valve place value of feeding back with described valve position sensor compares, if the deviation of detecting, according to automatically controlled instruction of size and Orientation output of deviation, give described electrically-controlled valve, the air mass flow of the actuator's air chamber described in described electrically-controlled valve and then adjusting turnover.
As preferably, described electrically-controlled valve comprises manifold valve, valve plate and baffler.
As preferably, on described valve position sensor, be connected with valve position warning device.
