Abstract
A digital-type electronically controlled valve with step motor and speed reducer, including angular stroke type and straight stroke type, is composed of main body, connecting frame, speed-reducing mechanism, step motor, handwheel, electronic valve position indicator, mechanical indicator for valve's open condition and screw lifter. It can directly receive digital pulse signals from computer, so having simplified control and higher response speed and control precision.
Description
The invention belongs to the valve control field of pipeline control system, specifically is a kind of with the direct digital-type electronically controlled valve that drives of stepper motor.
In the pipeline control system, generally adopt motor regulated valve and pneumatic regulating valve, motor regulated valve is big owing to inertia, and precision is low, and fault is many, poor reliability, thereby generally only be used for remote switch adjusting usefulness, be unsuitable for the frequent system that regulates.Generally adopt the pneumatic control valve door in the frequent system that regulates, but the pneumatic control valve door need be provided with independent source of compressed air, pressurized air brings noise, pollution and stops up easily, thereby increases maintenance difficulties.Control signal need be carried out electricity-gas shift, forms one by pneumatic baffle, film servovalve, film servo cylinder, feedback mechanism, valve etc. again and regulates closed-loop system automatically.Because gas has compressive characteristics, thereby degree of regulation is low, speed of response is slow, can not satisfy high-caliber regulating system requirement.For this reason, Japan has released the digital intelligent regulating valve (having applied for six state's patents) of collection mechanical-electrical-hydraulic integration, this patent is to use the step motor drive oil pump, through special oil circuit and selector valve driving oil cylinder or the oil motor of a cover, driving valve again finishes elevating movement or rotatablely moves the realization adjusting.Though this new technology has adopted stepper motor, not direct drive valve, but by oil pump, selector valve, hydraulic oil indirect drive, complex structure, owing to let out in having, the stroke of oil cylinder can not be corresponding one by one with the stepper motor pulse.And, owing to increased the hydraulic system of a cover closed cycle, not only improved cost, also increased maintenance difficulties greatly.
Continuous development along with computer technology and microelectronic technology, actuator in the pipeline control system is badly in need of a kind of complete receiving computer digital signal and drives, its displacement distance is digital-type electronically controlled valve one to one, and the present invention promptly finishes this purpose.
This digital-type electronically controlled valve that the present invention releases adopts the direct transmission of stepper motor, need not through the hydraulic pressure conversion, have simple in structure, advantage such as debugging is convenient, safeguards easily, and price is cheap.And valve moves (rotation) distance and pulse signal---corresponding.
The present invention will be further described below in conjunction with accompanying drawing.
Figure (1) is a structural representation of the present invention.
Wherein (1) is valve body, and it is various regulating valves such as butterfly valve, ball valve, stopcock, gate valve, seat valve or the like; (2) for connecting support, it is to play the effect that valve is partly linked with step motor drive, and an end is fixed on the valve, and the other end is fixed on drive part; (3) be reducing gear, play the effect that increases stepper motor strength, but for the valvelet no this item; (4) be stepper motor, play the angular displacement signal that the digital pulse signal of computer is converted to stepper motor; (5) be handwheel, play the effect of manual manual tune; (6) be valve regulated position electronic director; (7) be the valve opening mechanical display devices; The present invention is work like this: the digital signal of computer is given stepper motor (4) after power amplification, stepper motor is according to the angle of a correspondence of number of pulses rotation of digital signal, the input shaft of speed reducer (3) is passed in this angular displacement through connecting sleeve, after slowing down, export from lower velocity shaft, the rotatingshaft of regulating valve (1) is passed in this output shaft angular displacement through connecting sleeve, thereby make angle of regulating valve rotation, reach the purpose of once regulating.More than be the working principle of angular displacement regulating valve, if the straight journey regulating valve, speed reducer (3) output shaft then links to each other with spiral lifting mechanism (8), produces axial motion, moves so regulating valve produces on axial position.Its principle is all seen shown in pair figure:
Claims (6)
1. the digital regulated valve with stepping machine, speed reducer comprises valve body (1), connects support (2).It is characterized in that this digital regulated valve has adopted stepper motor (4) to drive.
2. stepper motor according to claim 1 is the various stepper motors that can receive digital pulse signal, comprises reaction equation, hybrid, magneto or the like stepper motor.
3. speed reducer according to claim 1 can be various speed reducer, also can omit this device when the strength of stepper motor is enough.
4. regulating valve according to claim 1 can be various regulating valves, comprising angular stroke control valve door and straight journey regulating valve such as butterfly valve, ball valve, stopcock, gate valve, seat valve or the like.
5. regulating valve according to claim 1 also has the handwheel controlling mechanism, can be with this handwheel switch valve when having a power failure.
6. regulating valve according to claim 1 also is provided with machinery and electronics valve indicator of opening, can show on the spot and long-range demonstration.
