Description

Intelligent gas valve adjusting method and adjusting system used by same
Technical Field
The invention belongs to the technical field of valve control, and particularly relates to an intelligent gas valve adjusting method and an adjusting system used by the same.
Background
In production and life, the use of gas cannot be separated from corresponding valves, and the precise control of the valves has direct influence on the improvement of the quality of products or services. The handle for directly and manually controlling the opening of the valve is generally provided with a rotating structure, but the relationship between the rotating angle and the gas flow, namely the firepower is generally nonlinear. Taking the use of a household gas stove as an example, one handle rotating interval corresponds to the maximum firepower, the firepower change is not obvious when the handle is rotated in the interval, and two handle rotating intervals are provided, and the firepower change is too fast when the handle is rotated in the intervals;
specifically, the handle rotation angle range is divided into three parts according to the dotted line position and the solid line position of the handle in fig. 1: the area between the handle solid line position and the closed position (home position) is referred to as a first angle interval, corresponding to the interval a1 in fig. 2; the area between the solid line position and the dashed line position of the handle is referred to as a second angular interval, corresponding to the interval a2 in fig. 2; the region between the dotted line position of the handle and the maximum rotation angle is called a third angle section, corresponding to the section a3 in fig. 2.
When the control handle is in the second angle interval (a2 interval), the combustion effect of the prior art direct control general gas valve is as shown in fig. 5, the air supply amount of the inner and outer fire dividers of the cooking range is near the maximum value, and the length of the arrow line in fig. 5 is long, which indicates that the fire power is uniform and maximum. Obviously, the change of the rotation angle of the control handle in the second angle interval has a remarkable nonlinear relation with the change of the firepower, which is equal to the waste of the angle interval, thereby occupying other angle intervals and forcing the gas flow to change too fast when the handle rotates in other angle intervals. When the control handle is in the first angle interval (a1 interval), the combustion effect of the conventional direct control general gas valve is as shown in fig. 6, the air supply amount of the inner and outer fire distributors of the cooking stove is significantly reduced, and the length of the arrow line in fig. 6 is significantly shorter than that in fig. 5, indicating that the fire is uniform and smaller. When the handle angle is in the first angle interval, the change of firepower is more acute to the change of the handle rotation angle. When the control handle is in the third angle interval, the combustion effect of the existing direct control general gas valve is as shown in fig. 7, the gas flow of the fire distributor in the cooking range is basically unchanged, and the gas supply rate of the outer fire distributor is too high along with the change speed of the rotation angle of the handle. Therefore, the existing gas valve has the defect that the opening of a valve flow passage is difficult to accurately control.
In addition, current gas valve when the handle rotates less or maximum position, takes place easily because of the gas flow undersize leads to unable problem of catching a fire or extinguishing easily, and then brings the risk that the gas leaked.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example one
As shown in fig. 4, the intelligent gas valve control system comprises a firepower control handle 2 (including an angular displacement sensor), an AD module 3, a controller 4, a motor driving module 5 and an electric regulating valve. The valve core 7 in the electric regulating valve is driven by a motor 6. Two valve body runners in the electric regulating valve respectively correspond to the inner fire distributor and the outer fire distributor; the opening degree of two valve body flow passages is through oneThe valve core is adjusted. The stroke of the valve core is divided into a synchronous control section and an asynchronous control section. The positions of the critical points of the synchronous control section and the asynchronous control section correspond to the internal and external separation critical value x of the rotation degree of the firepower control handle 2b. In the synchronous control section, the gas flow of the inner fire distributor and the gas flow of the outer fire distributor are changed synchronously; in the asynchronous control section, the gas flow of the outer fire distributor changes along with the movement of the valve core, and the gas flow of the inner fire distributor is kept constant. The shape of the firepower control handle 2 is the same as that of the adjusting handle of the existing gas stove. The firepower control handle 2 is fixed with an input shaft of the angular displacement sensor. A signal output line of the angular displacement sensor is connected with an analog signal input line of the AD module 3; the digital signal output line of the AD module 3 is connected to the controller 4. The controller 4 controls the rotation angle of the motor through the motor driving module 5 respectively and independently, thereby controlling the opening degree of the valve core 7 in the electric regulating valve. The two electric regulating valves respectively control an inner fire distributor and an outer fire distributor of the gas stove. The inner fire distributor and the outer fire distributor of the gas stove respectively form inner ring flame and outer ring flame of the gas stove.
The valve opening adjusting method of the intelligent gas valve control system comprises the following specific steps:
step one, a user rotates a firepower control handle 2 to control firepower of a gas stove, and an angular displacement sensor detects a rotation angle theta of the control handle 2 relative to an initial positionsAnd calculating the degree of rotation
Figure BDA0002675364710000051
θmaxThe maximum rotation angle of the fire control handle 2.
And step two, converting the rotation degree x into a digital signal through the AD module 3 and transmitting the digital signal to the controller 4. The controller 4 respectively controls the opening degree y of the valve body flow channel corresponding to the inner fire divider1＝sinα(π. x); valve body runner opening corresponding to external fire distributor
Figure BDA0002675364710000052
ηsThe value is the opening degree of a valve flow channel when the inner flame arrester is in constant fire, and is more than or equal to 0.3. Alpha is an adjusting parameter and takes a value of 2. x is the number ofbThe handle rotation degree corresponding to the boundary points of the synchronous adjusting area and the asynchronous adjusting area of the inner fire divider and the outer fire divider is 0.7 in the embodiment; when x is more than or equal to 0 and less than or equal to xbWhen y is1、y2Synchronous regulation when x>xbTime y1、y2Asynchronous regulation is carried out; y is1And y2The values are all a certain value between 0 and 1, the value of 0 represents that the valve body flow passage is closed, and the value of 1 represents that the opening degree of the valve body flow passage is maximum; opening y1And y2In the interval [0, x ]b]In the interval [ x ] ofb,1]Separating; the relationship between the valve flow and the fire power control handle rotation angle of the inner and outer fire dividers in this embodiment is shown in fig. 5.
Comparing the solid line and the dotted line in fig. 2 and 5, it can be seen that the second angle interval (a2 interval) in the rotation interval of the fire control handle 2 of the gas stove is compressed, and the first and third angle intervals (a1 and A3 intervals) are widened, thereby avoiding the defects that the fire of the existing gas valve is too sensitive to the change of the fire along with the rotation angle of the handle when the handle is in the a1 and A3 interval, and the fire is too slow to the change of the fire along with the rotation angle of the handle when the handle is in the a2 interval, and further making the control of the medium opening of the valve more linear when the handle rotates in the first and third angle intervals (a1 and A3 intervals), and the control of the small opening of the valve more fine and smooth.
Example 2
This example differs from example 1 in that: in the second step, the opening y of the valve body flow passage corresponding to the external fire distributor1Valve body runner opening y corresponding to inner flame separator2The magnitude of (d) is determined in table 1 based on the numerical value of the rotation degree x of the fire power control handle 2. For example, when the value of the rotation degree x is 0-0.10, the valve opening y corresponding to the inner and outer fire dividers1、y2Are all 0.03.
TABLE 1
Figure BDA0002675364710000061
It can be seen from the embodiments 1 and 2 that the compensation algorithm expressed by one analytic expression is difficult to achieve the ideal effect, and if a plurality of analytic expressions are used for expressing the compensation algorithm, the compensation algorithm is cumbersome, and has higher requirements on the controller. In addition, the fire demand level of the household gas stove is not too much, and 10 to 20 fire levels can meet the common cooking requirement. Therefore, the control system designed in this embodiment does not need to calculate any input angle of the control handle according to an analytical formula, but divides the input angle into a plurality of sections, assigns a valve opening value to each section and stores the valve opening value as a table, and the microcontroller only needs to judge which angle section the current handle is located in, and then queries the table to obtain the valve opening value. Thereby improving control efficiency and reducing the requirements on the controller.
Example 3
This example differs from example 1 in that: the rotation range of the fire power control handle 2 is divided into six sections which are respectively the initial constant closing section (0, theta)1]Initial constant current interval (theta)1，θ2]Inner and outer synchronous regulation interval (theta)2，θb]Internal and external asynchronous regulation interval (theta)b，θ3]Terminating the constant current interval (theta)3，θ4]Ending the constant closing interval (theta)4，θmax]。θ1、θ2、θ3、θ4Four corner demarcation thresholds are provided respectively. Theta1＝x1·θmax，θ2＝x2·θmax，θ3＝x3·θmax，θ4＝x4·θmax；θmaxThe maximum rotation angle of the fire control handle 2. x is the number of1、x2、x3、x4Four rotation degree demarcation threshold values respectively; in this example, x1＝10/160、x2＝15/160、x3＝130/160、x4＝135/160。
In the second step, the opening degree of the valve body flow passage corresponding to the external fire distributor
Figure BDA0002675364710000062
Opening degree of valve body flow channel corresponding to internal flame arrester
Figure BDA0002675364710000063
ηTHThe lower limit of the valve opening is 0.01 to 0.15. x is the number ofbThe meaning is the same as that of the first embodiment, and the value in the first embodiment is 0.7; opening y1And y2In the interval [0, x ]b]In the interval [ x ] ofb,1]Separating; the relationship between the valve flow and the fire power control handle rotation angle of the inner fire distributor and the outer fire distributor corresponding to the embodiment is shown in fig. 6.
This embodiment adds a means for preventing gas leakage to the technique of embodiment 1. In the conventional gas valve control method or the control method of example 1, the value is (0, θ)1]In the interval, the opening degree of the gas valve is very small, and the mixed concentration of the released gas and air is not enough to burn; at (theta)1，θ2]In the interval, the air supply quantity of the inner fire distributor and the outer fire distributor is small, the flame on the inner fire distributor and the outer fire distributor is also small, the phenomenon of flame jumping caused by burning and extinguishing alternately can occur, and at the moment, if the flame is blown out by wind, the fuel gas can leak. At (theta)3，θ4]In the interval, if the kitchen range is in the cold state, the mixed concentration of gas and air after the gas is escaped through the outer ring distributor is lower, probably can not be ignited by spark or the flame of inner distributor, so the gas can leak, or weak flame is not reburnt after being blown out by wind, and the gas still can leak. At (theta)4，θmax]In the interval, the mixed concentration of the gas released by the outer ring distributor and the air is lower than the combustion threshold, and the gas is leaked certainly. Although the actual gas range has a flameout protection device, the device is set at (theta)3，θ4]The sum of the intervals (theta)4，θmax]In the interval, because the gas flow of the inner distributor is sufficient enough to enable the flame detector (generally a thermocouple) to judge normal combustion, a small amount of gas escaping from the outer distributor is ignored and cannot trigger the action of the flameout protection device. Therefore, the valve opening control mode of the tappet is safer and more energy-saving.
Example 4
As shown in FIG. 7, the present embodiment is different from embodiments 1 to 3 in that: intelligence gas valve control system still includes the display screen9 and a display driving module 8; the controller 4 controls the display screen 9 through the display driving module 8. A display content generation module is arranged in the controller 4; the display content generation module generates a display content according to the opening y of the valve1And y2The current firepower degree is displayed on the display screen 9; the display content on the display screen 9 can be X minutes of fire (such as 10 minutes of fire and 5 minutes of fire) or real-time heating power. Compare in embodiment 1 ~ 3, this embodiment not only provides the gas-cooker safer, that change control firepower, still provides the support for exchanging the duration and degree of heating control method among the culinary art.
Example 5
The present embodiment is different from embodiments 1 to 3 in that: y is2、y1The opening degree of the valve body flow passage corresponding to the outer igniter and the inner igniter is not shown; but rather, the corresponding gas flow rates of the outer and inner igniters. The gas flow is adjusted through the opening of the valve; the corresponding relation between the gas flow and the valve opening is obtained through test calibration.
