Description
Technical field
The present invention relates to a kind of Inspection and monitoring system regulating valve, specifically a kind of regulation valve Intelligent Measurement monitoring is
System.
Background technology
Various regulation valve is widely used in modern petrochemical, and the running status of regulation valve directly affects the matter of chemical products
Amount and safety.Regulation valve is the most electronic or pneumatic, is all that control system controls electric current (4-20mA), localizer root to localizer
Driving actuator according to controlling electric current, actuator promotes the upper and lower motion of valve rod, thus reaches to control the position of valve spool of valve,
To reach to regulate the function of flow (pressure).
Traditionally, its operation principle all, provides control given value of current position device, positioner feedback signal by control system
Electric current is to control system, it can be seen that, the signal input in this circulation, output are all that localizer is given, but if location
There is error in device, it is impossible to the position of accurate feedback valve rod, then bring hidden danger to whole control system, even bring safety problem.
Summary of the invention
The technical problem to be solved in the present invention be to provide one can accurate response valve rod duty, detection reliability is high
And the regulation valve Intelligent Measurement monitoring system that precision is high.
In order to solve above-mentioned technical problem, the regulation valve Intelligent Measurement monitoring system of the present invention, including being connected on valve rod
Connecting rod and the sensor that is connected with connecting rod, sensor at least include displacement transducer, angular transducer, temperature sensor,
One in pressure transducer, flow transducer and gas sensor, described sensor connects one by analog-to-digital conversion module
Individual processor module, sensor can detect the various data messages of valve in real time and be exported everywhere by the data message detected
In reason device module, processor module connects control output module and signal output module, processor die by D/A converter module
The data message received can be processed and output to control in output module and signal output module by block.
Described control output module includes voltage output module and current output module.
Described signal output module at least includes WIFI signal output module, Bluetooth signal output module and USB interface
In one.
Described processor module connects display module.
Described processor module connects power module.
Reference current input module it is also associated with on described connecting rod.
After using above-mentioned structure, can directly detect valve rod, measure the misalignment of valve rod, and receive with localizer
Control signal electric current compares, and compares positioner feedback to the signal code of control system, thus anti-fastening
The error of position device, thus substantially increases accuracy of detection, by processor module, the data collected is analyzed, is counted simultaneously
Calculate, thus search out regulation valve duty in systems, feed back to control system, such that it is able to obtain each regulation valve quality
State trend, in order to control system carries out early warning to contingent fault, and detection reliability is improved.
Accompanying drawing explanation
Fig. 1 is the theory diagram that the present invention regulates valve Intelligent Measurement monitoring system.
Detailed description of the invention
