Abstract
An intelligent non-contact valve controller belongs to the technical field of control devices, and comprises a power supply start-stop device, a motor protector, a solid relay and a controller, wherein the power supply start-stop device is connected with the solid relay, the solid relay is connected with the motor, and the power supply start-stop device, the motor protector and the solid relay are connected with the controller. The power supply start-stop device comprises tripper optically-coupled silicon controlled rectifier and a bidirectional silicon controlled rectifier, wherein the tripper optically-coupled silicon controlled rectifier uses MOC3041, and the bidirectional silicon controlled rectifier uses BTA12. The motor protector comprises an inductance transmitter and a Schmitt trigger silicon controlled rectifier, wherein the Schmitt trigger silicon controlled rectifier uses HHD2-B/Z. The solid relay uses SSR380-25A. The controller comprises a singlechip, a liquid crystal display screen and a control element, wherein the singlechip uses STC89C58, and the liquid crystal display screen uses JM12864-J. The intelligent non-contact valve controller has the characteristics of reasonable design, simple structure and excellent control effect, which eliminates the production of sparks from sources.
Description
Technical field
The utility model relates to a kind of intelligent contactless valve positioner, belongs to the control gear technical field.
Background technique
At industrial control field, generally be by operational order action, the process of action and result can't visual expressions, though the demonstration of high-grade numerical control system is perfect, cost an arm and a leg, and are unable to reach.Mostly electric valve control field is the mode of relay control, but use occasion is restricted, and for flammable, explosive occasion just can not adapt to.With the raising of usage requirement, though the making of no-spark controller is also arranged, but still can not accomplish that really still there is hidden danger in definite no-spark.
Summary of the invention
At the defective of prior art, the utility model provide a kind of reasonable in design, simple in structure, control is respond well, intelligent contactless valve positioner that arc control produces from the source.
A kind of intelligent contactless valve positioner; form by power supply start and stop device, motor protecter, solid-state relay and controller; power supply start and stop device is connected with solid-state relay, and solid-state relay is connected with motor, and power supply start and stop device, motor protecter, solid-state relay all are connected with controller.
Described power supply start and stop device is by trigger optocoupler controllable silicon, and bidirectional triode thyristor is formed, trigger optocoupler controllable silicon MOC3041, bidirectional triode thyristor BTA12.
Described motor protecter is by inductive pick-up, and this schmitt trigger controllable silicon is formed, this schmitt trigger controllable silicon HHD2-B/Z.
Described solid-state relay SSR380-25A.
Described controller is made up of single-chip microcomputer, liquid crystal display panel and control unit, single-chip microcomputer STC89C58, liquid crystal display panel JM12864-J.
The contactless valve positioner of the utility model intelligent control, outstanding being embodied in " intelligence " and " contactless ".It comprises contactless on/off, motor positive and inverse control, and the protection of motor all is contactless control.Intelligence points out you to press operating procedure with liquid crystal screen exactly, and display action process and the result of the action have been realized human-computer dialogue, allows the operator come into plain view.
The utlity model has reasonable in design, simple in structure, control is respond well, characteristics that arc control produces from the source.
