Description of drawings
Accompanying drawing is the control flow chart of rotation cleaning unit of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, specifically describe embodiments of the present invention.
Automatic heating control device of the present invention, be installed on the hot duct, comprise main control unit, timer, control motor, motor current detection device, heat supply valve, valve positioner etc., main control unit can be single-chip microcomputer or other logic control circuits, control motor by control program, motor can be direct current generator or stepper motor, the unlatching of motor-driven heat supply valve or close, and then realize the automatic switch of heating installation; Electric Machine Control heating valve opening angle influences the heating agent flow, realizes the automatic adjusting of heating temperature.Similar automatic heating control device is used more in practice, and for example Chinese patent CN200620018228.4 has just disclosed a kind of like this heating control device.
But because China heating water quality is relatively poor, is installed in the heat supply valve of the automaton on the heat supply pipeline and impurity such as incrustation scale, scale can often occur, cause the control accuracy of control heating control device to descend, even can not normally move.Therefore, the present invention makes full use of the characteristics of existing automatic heating control device, has increased the rotation cleaning unit, comprises following steps:
1, device is provided with valve rotation period of time T;
Heating control device can be in advance valve-embedded the numerical value of rotation period of time T, also can pass through input equipment, as input T values such as external keyboard.According to the difference of heat supply water quality condition, the T value is generally during 5-7 days.
2, with T be time-count cycle, timer picked up counting from the current time;
Installing built-in software or hardware timer is time-count cycle with T, picks up counting from the current time.
3, when the automatic heating control device is in running order, per blanking time T, main control unit sends the instruction of valve rotation cleaning, the certain cleaning angle T of control motor-driven heat supply valve rotation on the basis of current opening angle Φ, return current opening angle.
For spherical by-pass valve control, it is 360 degree angles from circling, and two weeks of rotation then are 720 degree angles, by that analogy.Therefore, if select rotation cleaning angle value T ΦIt is the integral multiple of 360 degree, then valve is circling or N (N=1 after week certainly, 2,3 ... natural number), will get back to the current opening angle value before rotation begins again, and for main control unit, send the control instruction of a certain preset parameter, making valve rotate a week (360 degree) is unusual nothing the matter feelings, can obtain the control corresponding parameter value by prior experiment easily.Therefore, selecting the rotation angle of the integral multiple of 360 degree, is to select eaily for spherical by-pass valve control.
But in actual application, consider factors such as valve thermal expansion influence, pipeline fluid pressure, may cause the heat supply valve departure of certain limit to occur, valve not necessarily can accurately be got back to current initial opening angle position after acquiescence is rotated the N*360 degree under the main control unit control.
Therefore, as the further improvement of the technical program, main control unit is noted current valve opening angle, as the corrected value after the rotation when the rotation instruction is sent.Need the heat supply valve to have positioner simultaneously, can be continuously or the opening angle position of discreteness location valve, and feed back corresponding framing signal and give main control unit.Main control unit is adjusted opening angle according to the feedback signal of valve positioner, to reach the purpose of accurate by-pass valve control rotation and opening angle.
Similarly the valve positioner also has multiple application type in practice, in one embodiment of the invention, adopted the positioner of a kind of Weight and disk type heat supply valve of Chinese patent ZL200620166356.3, comprise fixed head and code-disc, this code-disc comprises fan-shaped substrate, be provided with even spaced apart rectangle double wedge and groove on its circular arc limit, be provided with described detent mechanism, be provided with at the center of circle of fan-shaped substrate end and be used for the installation sleeve that is connected with valve rod on a double wedge top at edge; Be separately installed with initial position alignment sensor and sensor for countering at fixed head with respect to the detent mechanism on fan-shaped substrate one side and the double wedge part of another side, utilize two optoelectronic switches under the cutting of fluted disc, the received signal of light sensation is determined the position at valve place, the location, position of heat supply valve can be provided accurately, thereby determine the accuracy of valve opening angle, improve the degree of reliability of product.
4, after the heat supply valve is got back to current opening angle, main control unit is with the timer zero clearing, the timing of a beginning new round, promptly reach time-count cycle once more during T when timer, main control unit is noted current valve opening angle, send valve rotation cleaning instruction simultaneously, control motor-driven heat supply valve certain cleaning angle T of rotation once more on the basis of current opening angle Φ, and then get back to current opening angle.
When 5, the rotation cleaning unit of this heating automaton started, control motor-driven heating valve rotation certain angle was with impurity such as the incrustation scale in the cleanser conduit, dirts.If but impurity is too much or other reasons sometimes; may cause the heating valve because resistance too greatly can not normal rotation; the electric current that control motor this moment will strengthen; in case detecting motor current value, motor current detection device surpasses default current parameters value; showing that the heating valve rotates is obstructed, and then main control unit will control the motor counter-rotating, reverse thereby drive the heating valve; with the protection motor, and realize the purpose that rotation is cleaned.The heat supply valve comes back to current opening angle after carrying out reverse turn operation.
The current sensing means here can adopt existing current detection circuit, current detecting chip etc.
