Specific embodiments:
Be adjusted to example to be applied to gaseous-pressure below,, button Long-distance Control and closed-loop control be elaborated in conjunction with accompanying drawing:
As shown in Figure 1; Loam cake (9) in common gases pressure regulator (1) is gone up fixed electrical machinery support (2); The reducing motor or the stepper motor (6) of band rotating are installed on the electric machine support (2), and the rotating torque transmission of motor shaft (5) is given by pin (7) and square axostylus axostyle (8) is connected and pressure regulator valve initial tension of spring set screw (4) is combined into scalable shaft coupling.When reducing motor axle (5) turns clockwise (just changeing); Initial tension of spring set screw (4) is rotation synchronously under the twisting force of square axostylus axostyle (8); Rely on the screw thread of gas pressure regulator, governor loam cake (9) to move down simultaneously; The pretightning force of pressure spring (3) is increased, and the pressure of the outlet (10) of common gases pressure regulator (1) increases.In like manner, when the reducing motor axle reversed, initial tension of spring set screw (4) was moved up by the acting force of pressure spring (3), and the pretightning force of pressure spring (3) reduces, and the pressure of the outlet (10) of common gases pressure regulator (1) reduces.
The motor (6) of band rotating is connected with power supply (11) shown in figure (2); Open switch (12), when the top hole pressure that needs pressure regulator increases, just pin and just changeing keyswitch (13); The reducing motor (6) just turn clockwise (just changeing) of band rotating; When needs reduce the pressure regulator valve top hole pressure, just pin reverse button switch (14), the reducing motor (6) of band rotating just is rotated counterclockwise.
Shown in Figure 3, switch (19) is when pushing manual position, and is basic identical shown in principle of work and the figure (2); Switch (13) presses & hold; Just changeing relay (15) energising, J1 is logical to close closing of contact synchronous motor (6) just changes the switch that presses & hold (14); Counter-rotating relay (16) energising, the logical closing of contact synchronous motor (6) that closes of J2 reverses; Switch (19) is when pushing automated location; Signal converter (20) is started working; The pressure transducer (17) that is installed in gas pressure regulating valve outlet (10) detects the pressure of actual pressure and setting when inconsistent, industrial computer (18) just automatically connection just changeing relay (15) or the relay (16) that reverses, synchronous motor is carried out rotating control moves; When gas pressure regulator, governor top hole pressure plate was adjusted within the error range of permission, synchronous motor was out of service.Accomplish and accurately set the pressure regulator top hole pressure.
The utility model is for only needing continuous adjustments of gas pressure; Perhaps only set several different pressure; At this moment only use the rotating reducing motor, can be through artificial monitor pressures table, by just changeing or invert button; Just can realize the remote pressure adjusting, not need servomotor and pressure transducer and converter; For need be to the setting of a lot of different pressures; Can use servomotor and pressure transducer and converter; The actual pressure signal that measures according to pressure transducer; Through having the industrial computer of comparer, form automatic feedback control (closed-loop control), thereby obtain various accurate gaseous tensions.If increase a switch again, then can realize pressure setting control (closed-loop control) and button Long-distance Control respectively.
