Description

A kind of rectangle intelligent valve positioner

Technical field

The present invention relates to a kind of detent mechanism, more particularly, refers to a kind of rectangle intelligent valve positioner.It is to utilize External air source is driven come the stroke of the cylinder to promotion valve actuator, realizes to adjustment type valve or switch valve opening Control locator.

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.

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.

2. 2. rectangle intelligent valve positioner according to claim 1, it is characterised in that：In the cavity (1C) of upper lid (1) Surface is coated with electro-magnetic screen layer.
3. 3. rectangle intelligent valve positioner according to claim 1, it is characterised in that：The inner wall surface plating of base (2) There is electro-magnetic screen layer.
4. 4. rectangle intelligent valve positioner according to claim 1, it is characterised in that：Displacement measuring device (6) is connecing After the angular displacement S for receiving external feedback, main shaft (6D) rotates, then drives rotating disk (6A) to rotate；The motion of rotating disk (6A) Drive angle stroke gear wheel (6B) servo-actuated；In the outer sliding tooth (6B2A) and interior sliding tooth (6B1A) point of angle stroke gear wheel (6B) Lower driven tooth (8F3A), upper driven tooth (8F12) not with gear shaft (8F) engage down, and it is 0.5 to realize modulus, outer sliding tooth (6B2A) is 1 with lower driven tooth gearratio:3rd, interior sliding tooth (6B1A) and upper driven tooth (8F12) 4:33 transmission；Gear shaft The motion of (8F) drives potentiometer (81) to rotate, and causes angular displacement to export an electric signal through potentiometer (81)；Gearratio Conversion controlled by transposition cam (8C), when around A axis clockwise rolling transposition cams (8C) to extreme position when, shift gears support (8D) rotates around B axle line clockwise, makes the lower driven tooth (8F3A) of gear shaft (8F) and the outer driving of angle stroke gear wheel (6B) Tooth (6B2A) engages, gearratio 1:3；Conversely, the upper driven tooth (8F12) of gear shaft (8F) and angle stroke gear wheel (6B) Interior sliding tooth (6B1A) engagement, gearratio 4:33.
