Technical field
The present invention relates to a kind of mortor operated valve, especially a kind of novel mortor operated valve valve position automatic control tegulatingdevice.
Background technique
Electric control valve is widely used in the adjustment to pipeline liquid, gas etc., mortor operated valve valve position domestic at present regulates and generally adopts motors of electric valves axle to drive multiturn potentiometer with display, the size of valve seat opening reflects the change of potentiometer resistance, be equipped with vision-control instrument to show the aperture of valve position and to carry out the automatic adjustment of valve position, because potentiometer is in long term wear state, its life-span is often very short, has a strong impact on the use of product.
Summary of the invention
For solving an above existing difficult problem, the invention discloses a kind of novel mortor operated valve valve position automatic control tegulatingdevice.
A kind of novel mortor operated valve valve position automatic control tegulatingdevice, described automatic control tegulatingdevice comprises angular displacement sensor, thermal resistor, temperature digital display regulation meter and electric servo amplifier, described thermal resistor electrical connection temperature digital display regulation meter, described temperature digital display regulation meter electrical connection electric servo amplifier, described electric servo amplifier electrical connection angular displacement sensor.
Further, described thermal resistor half embeds in pipeline.
Further, described electric servo amplifier is DF-1 electric servo amplifier, and described temperature digital display regulation meter is XMT-192 temperature digital display regulation meter.
Beneficial effect: the angular displacement sensor in the present invention replaces the potentiometer of contact-type, coordinate electric servo amplifier, mortor operated valve valve position is controlled automatically, mechanical angle displacement is turned to electrical signal, non-contact measurement, there is resolution high, temperature stability is good, and reliability is high, close to the infinite rotational life-span, solve the impact because life of equipment, problem caused product, fill up the blank of domestic like product, to increase productivity and domestic automatic production quality serves important function.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is control of valve position theory diagram.
Wherein, 1, angular displacement sensor, 2, thermal resistor, 3, temperature digital display regulation meter, 4, electric servo amplifier.
Embodiment
By reference to the accompanying drawings, the present invention is described in further details.
As shown in the figure, a kind of novel mortor operated valve valve position automatic control tegulatingdevice, described automatic control tegulatingdevice comprises angular displacement sensor 1, thermal resistor 2, temperature digital display regulation meter 3 and electric servo amplifier 4, described thermal resistor 2 is electrically connected temperature digital display regulation meter 3, described temperature digital display regulation meter 3 is electrically connected electric servo amplifier 4, described electric servo amplifier 4 is electrically connected angular displacement sensor 1, described thermal resistor 2 half embeds in pipeline, described electric servo amplifier 4 is DF-1 electric servo amplifier, described temperature digital display regulation meter 3 is XMT-192 temperature digital display regulation meter.
Embodiment: when pipeline water temperature is lower than setting value, records pipeline water temperature lower than setting value by thermal resistor 2, and temperature digital display regulation meter 3 sends instruction to electric servo amplifier 4, electric control valve valve position is increased, steam flow increases, and pipe temperature rises, and temperature is controlled at desirable value; When pipeline water temperature is higher than setting value, record pipeline water temperature higher than setting value by thermal resistor 2, temperature digital display regulation meter 3 sends instruction to electric servo amplifier 4, electric control valve valve position is reduced, steam flow reduces, and pipe temperature declines, and controls temperature at desirable value.
