Description
The utility model relates to a kind of multi-functional valve position signal generator to the valve opening and closing working state monitoring.
Valve is widely used visual plant parts in the industries such as industrial and mining enterprise, petrochemical industry, communications and transportation; along with computer application and development; in a lot of industrial control occasions; for realizing concentrated controling management; Monitoring and Controlling to the valve working state is the important step of whole process of production, technological process, safety protection, and is annual according to statistics in the control valve process, because the valve that staggers; and often have an accident, cause great personnel and property loss.The various in recent years solenoid valves that can control, pneumatic valve, mortor operated valve, extraordinary valve is constantly come out one after another, and valve position is accurately controlled in developing into single-chip microcomputer of having.But defective such as exist poor reliability, cost an arm and a leg can only small lot be used on the critical process position, can not replace to account for the various manually-operated gates of utilization rate more than 90%.And many electromagnetism, pneumatic, mortor operated valve all do not have the state signal of keying feedback yet, can't adapt to modern industry requirement valve centralized detecting or control.
The utility model purpose is on the valve basis of original use, does not change former valve mechanism, and the signal-transmitting machine that high concentration monitoring valve working state is convenient in a kind of non-contact is set.
The utility model is by being positioned at the signal generator on the valve body handwheel and being positioned at signal receiver on the valve body, the signal receiver circuit is formed, signal receiver is installed on the valve rod supporting sleeve, the inside top of Receiver shell is equipped with probe, the signal receiver circuit is installed in middle part in the Receiver frame, the Receiver frame is installed on the base, base is fixed on the valve body by support, the Receiver frame is provided with display lamp and reset signal indicator, signal inserts current amplification circuit by the end output of hall detection component, the emitter of current amplification circuit inserts secondary meter control processing circuit, be connected to the demonstration light emitting diode in the collector circuit, working signal indicating circuit and sound light alarming circuit insert the secondary meter control circuit respectively, and the signal transmitter of being made up of little magnet steel or shading sheet is installed in the below of valve handle.
The utility model structural principle is simple, adapt to wide, reliable performance, easy for installation, can directly the valve position mechanical motion be changed into digital signal output.Can single direct control performance element, also can tens, up to a hundred carry out high concentration through secondary meter and carry out control processing.Because the utility model all adopts the intrinsically safe circuit design, not only satisfies the needs that the general environment occasion is used, and satisfies the needs that chemical industry, oil etc. contain explosive gas mixture particular surroundings occasion.
Accompanying drawing 1 is the utility model structure sectional view.
Accompanying drawing 2 is the utility model detector electronics schematic diagram.
Accompanying drawing 3 is the utility model mounting point schematic representation.
Below in conjunction with accompanying drawing the utility model is further described, the utility model is by the valve position signal generator, and the Receiver two large divisions forms.Receiver is a cylindrical structure, be installed on the valve rod supporting sleeve 1, in be equipped with and detect sensing element and control circuit 4, as a whole with the epoxy resin glue envelope, output line is afterbody at the bottom of cylinder, the inside top of Receiver shell 2 is equipped with control 3, frame is installed on the base 5, and base is fixed on the valve body 7 by support 6, and receptor surface is provided with LED modules with different colors electronics display lamp 8 and reset signal indicator 9, carry out valve position work clothes attitude, misoperation shows.Signal generator 15 is made up of little magnet steel or shading sheet.During work Receiver can be fixed on the valve body or valve body near certain benchmark fixed position on, the valve position signal generator can be installed in according to the requirement of various valve position detection in valve handle, valve rod or other opening-closing processes on the back and forth movement machinery position.Because the photoelectricity in the Receiver, the responsive Detecting element of magnetoelectricity are by the top that is placed in the Receiver.When valve when opening work, the valve position signal generator is because positive hour hands of handwheel, counterclockwise.About the valve rod, or operative section presses several angle and comes and goes, and other modes are when moving near Receiver, produces light, magnetic signal is done and is used for Receiver.Detecting element 10 in the Receiver, the valve position signal of surveying is transformed into current signal, write down, store, pass through transmission line, pass to secondary meter processing circuit 12 at a distance in the electric current loop mode, or actuator's processing, when the needs accuracy detection, signal generator can be provided with a plurality of according to actual needs.Thereby realize the valve position detection to all types of valves, working signal indicating circuit 13 and sound light alarming circuit 14 insert the secondary meter control circuit respectively.The utility model working principle is such, the valve position signal generator is installed in below the gate valve handwheel as shown in the figure, Receiver is installed between valve body and the handwheel, when the operator drives valve, rotate handwheel, positive hour hands are opened or are closed when doing the angular displacement campaign photoelectricity that signal generator sends or magnetoelectricity signal counterclockwise, the sensing element that is accepted in the device is accepted to amplify processing, directly the position, angle is converted to corresponding digital signal.Export to secondary meter or carry out control mechanism by transmission line on the one hand,, will directly demonstrate the valve position working state in receptor surface on the other hand, be convenient to operator and observe so that the control personnel carry out manual intervention.
Secondary meter is held to determine valve position open amount size state by ABC.D holds the given order end of exporting to valve for secondary meter, and when opening and closing valve, under manual intervention, the valve order is left in the output of secondary meter circuit, all will produce acoustooptic alarm if stagger or forget closing valve, till artificial throttle down.
The utility model not only is applicable to gate valve, is applicable to that also the valve of other types such as stop valve, ball valve, dish valve is installed and used.
