Description

A kind of circular intelligent valve positioner

Technical field

The present invention relates to a kind of detent mechanism, more particularly, refers to a kind of circular intelligent valve positioner.It is to pass through control External air source flow processed is driven come the stroke of the cylinder to valve actuator, realizes and adjustment type valve or switch valve are opened The locator of the control of degree.

Background technology

Production process automatically controls abbreviation process control, and it occupies extremely important status in the industrial production.Process The quality of control is largely determined by Controlling Apparatus for Processes, and it includes transmitter, adjuster, actuator and various auxiliary Control device etc..One kind auxiliary control instrument is called valve positioner, is the object that various countries are competitively studied, it is to a certain extent The regulation quality of process control is determined, and with the horizontal development of process control, locator must be also continued to develop to meet Requirement of the modern production to process control.

Valve positioner, divide pneumatic positioner valve, electropneumatic valve positioner and intelligent valve positioner by structure, be to adjust The main accessories of valve are saved, are generally supported the use with pneumatic control valve, it receives the output signal of adjuster, then with its output Signal goes to control pneumatic control valve, and after valve events are adjusted, the displacement of valve rod feeds back to valve positioner further through mechanical device, Valve position situation is transmitted to Upper system by electric signal.

Before more than 50 years, control (or automatic feedback process) loop is all gas-powered, transmitter, adjuster and last Control unit (such as a regulating valve) is joined together and mutually communicated by 20-l00KPa pneumatic signal, this Individual signal also is used for driving the executing agency of last control unit as a power source.In many aspects, this is still just True.But in some cases, for example, the position reaction of valve or change speed it is too slow, the execution machine required for the valve of large-size When structure is too big, reuses low air pressure signal as 20-100KPa and be just unable to reach expected control purpose and control accuracy. In order to solve this problem, pneumatic positioner valve is developed.Pneumatic positioner valve is in adjuster output and valve location Between play the part of the role of volume regulator, signal amplifier and relationship controller.Air pressure signal to locator operates a gas Body relay, gas relay are operated sequentially a guiding valve or nozzle-baffle mechanism.In locator, position pass through one Cam determines.Why spring is applied in last control unit, to ensure executing agency when air pressure reduces Back reaction.

The input signal of electropneumatic valve positioner is 0~10mA DC signal, is exported as air pressure signal.It can rise To the two kinds of effects of electropneumatic transducer and pneumatic positioner valve.It receives the signal of electric controller, it and pneumatic control valve Support the use.Electropneumatic valve positioner can be used for controlling pneumatic Direct Travel or angular stroke control valve；Bullet has been also applied for it simultaneously The single-acting state of spring executing agency and the double acting situation without spring acuator；It is alternatively blast resistance construction and non-explosion-proof knot Structure.It is worked by principle of moment balance, and its maximum difference with pneumatic positioner valve is that it positions operated pneumatic valve The bellows of device changes torque-motor into.When signal code is passed into the coil both ends of torque-motor, it is acted on permanent-magnet steel Afterwards, a torque is produced to main lever, then for baffle plate close to nozzle, the output pressure after amplifier amplifies is passed into execution machine The cylinder of structure, feedback spring is stretched by feeding back cam, spring acts on main thick stick to the feedback moment of main lever with input current When torque on bar balances each other, instrument reaches poised state.Now, certain input current just corresponds to certain valve location.

70~beginning of the eighties, such a locator account for 85%~90% in China's use range, and mechanical force balanced structure lacks Putting is:Environment resistant difference, easily influenceed by temperature, extraneous vibration, it is easy to wear, manually adjust time-consuming and need to interrupt control loop. But because its is cheap, still used in the traditional forms of enterprises.

Electronic positioner for electric valve starts to move towards market at the beginning of the eighties, and technological means was constantly updated in recent years.Line Property potentiometer stem position is converted into electric signal and initial set value compares, by the adjustment of PI controllers and signal amplification output To piezoelectric micro valve, output pressure is controlled, is exported through pneumatic amplifier.When input signal and feedback signal balance, pneumatically put The stable pressure signal of big device output, ensures that regulating valve is accurately positioned.As can be seen here, control principle is totally different from past machine The comparison of tool force balance principle, set-point and actual feedback is entirely electric signal, is no longer dynamic balance, reduces intermediate transfer Link, some problems in power transmission and transfer process are eliminated, improve antijamming capability.Wherein electric conversion element is using pressure Electric miniature valve, piezo electric valve have outstanding advantages of small quick action, quality, long lifespan, complete while gas circuit balance is realized Accurate transformation into electric signal to gas signal.

With the continuous development of microelectric technique, the integrated level more and more higher of microprocessor chip can be in one piece of core CPU, memory, timer/counter, even parallel and serial interface, A/D converter etc. are integrated on piece simultaneously.People are this Kind VLSI chip is referred to as " single chip microcontroller ", referred to as single-chip microcomputer.The appearance of single-chip microcomputer, causes instrument The fundamental change of instrument structure, the conventional electrical circuit of traditional instrument instrument is substituted using single-chip microcomputer as main body, can be easy Computer technology and survey control technology are combined together, formed so-called " the intelligent measuring control instrument " of a new generation.This Kind new intelligence instrument is in the automation of process, the variation aspect of data processing and function, all achieves and huge enters Exhibition.

It is the VALTEK companies proposition intelligent supervisor IVM (IntelligentValve in his outstanding state of the U.S. earliest Manager novel concept), present locator self diagnosis and communication etc. function constantly strengthen, intelligent valve positioner into For the focus of the research of instrument and meter company of various countries, exploitation.Intelligent Electrical Valve Positioner is with microprocessor (MCU) for core control Device processed, complete to be accurately positioned operated pneumatic valve using advanced digital control algorithm, and a system is carried out to it on this basis The Function Extension of row and enhancing, the wider valve positioner of application is intellectual valve positioner mostly at present, it and common valve Door holder has been compared significant advantage in performance, service condition, the ratio of performance to price etc..

The study hotspot of locator essentially consists in intelligent valve positioner at present, what the electropneumatic valve positioner used used It is mechanical force balance principle, comes with some shortcomings and can not meet the needs of process control development.Intelligent valve positioner collection Machinery, electronics, communication and control theory knowledge and related software knowledge have been closed, has been an intelligent artifact interdisciplinary.Changing The Military and civil fields such as work, pharmacy, electric power, material, scientific research, life science, mechanical industry, electronics industry have very extensive Application prospect.
