Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, and in particular to an intelligent control ball valve based on data analysis. Background Art

[0002] A ball valve is a valve whose spherical opening and closing member is driven by the valve stem and rotates around the axis of the ball valve. It can be used for fluid regulation and control. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It only needs a 90-degree rotation and a very small torque to close tightly. Ball valves are most suitable for use as switches and cut-off valves.

[0003] When the ball valve is in use, the valve stem is usually driven by a motor to rotate 90 degrees to achieve the switching effect. After long-term use, a large amount of scale may adhere to the outer surface of the ball opening and closing part inside the ball valve. These dirt or impurities will increase the volume of the ball valve core, resulting in difficulty or inability to rotate the ball valve. On this basis, the load on the motor when switching the ball valve increases, and it may be damaged after long-term use. Therefore, in order to avoid this situation, users will formulate a fixed maintenance and cleaning cycle for the ball valve according to its service life, so as to avoid dirt or impurities on the outer surface of the ball opening and closing part clogging the sealing surface of the ball valve, thereby increasing the service life of the motor.

[0004] In order to ensure the normal rotation of the ball valve in the prior art, a fixed maintenance and cleaning cycle is usually set for the ball valve based on past experience. However, the scale attached to the outer surface of the ball opening and closing member is related to the water quality. If the water quality is good for a period of time, a large amount of scale will not be generated. At this time, if the maintenance and cleaning is performed according to the fixed maintenance and cleaning cycle, the cleaning benefits will be small. On the contrary, if the water quality is poor for a period of time, the scale formation speed will be accelerated, and the ball valve may become difficult to rotate before the set maintenance and cleaning day, thereby affecting the normal use of the ball valve and even the service life of the motor.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 As shown, in one embodiment, the present application provides an intelligent control ball valve based on data analysis, including a valve body 1, a mounting seat 2 is fixedly connected to the top of the valve body 1, a connecting hole is opened at the bottom of the mounting seat 2, the connecting hole penetrates the interior of the valve body 1, a valve stem 31 is rotatably connected to the connecting hole through a sealing O-ring, and a ball valve core 36 is fixedly connected to the bottom of the valve stem 31;

[0041] The top of the mounting seat 2 is fixedly connected with a shell 3, and a first driving component is arranged in the mounting seat 2, and the first driving component is used to drive the valve stem 31 to rotate. The top of the valve body 1 and both sides of the ball valve core 36 are provided with mounting grooves 4, and connecting rods 42 are slidably connected in two groups of the mounting grooves 4. The outer wall of one side of the two groups of connecting rods 42 close to the ball valve core 36 is fixedly connected with a first arc-shaped grinding brush 43, and a second driving member is arranged in the mounting groove 4, and the second driving member is used to drive the connecting rod 42 to move in the mounting groove 4;

[0042] A communication module is provided in the housing 3, and the communication module is electrically connected to the management end. A remote monitoring module is provided in the housing 3, and the remote monitoring module is used to detect the state information of the first driving component when it is working, and transmit it to the management end through the communication module;

[0043] The management end includes a data processing module and a data analysis module. The data processing module is used to calculate the risk value of the operating state of the first drive component according to the data detected by the remote monitoring module, and to analyze and judge the operating state of the ball valve according to the calculation result through the data analysis module, and to decide whether to use the first arc-shaped grinding brush 43 to clean the ball valve core 36 according to the analysis result;

[0044] Through the above technical solution, when the ball valve is used, the valve stem 31 is first driven to rotate by the first drive component. During the rotation of the valve stem 31, the ball valve core 36 at the bottom thereof will be driven to rotate synchronously, thereby realizing the opening and closing of the ball valve. During this process, the remote monitoring module will collect the state information of the first drive component when it is working, and transmit it to the management end through the module. Subsequently, the data processing module in the management end calculates the risk value of the operating state of the first drive component according to the collected information, and then compares the risk value of the operating state of the first drive component with the preset risk value threshold of the operating state through the data analysis module, and judges the operating state of the ball valve according to the comparison result.

[0045] If the ball valve is judged to be in good operating condition, no cleaning operation will be performed on it. If the ball valve is judged to be in poor operating condition, it means that there may be a lot of scale or impurities on the outer surface of the ball valve core 36. At this time, the management end will issue an instruction to the second drive component to drive the two groups of connecting rods 42 to move through the second drive component. During the movement of the two groups of connecting rods 42, the first arc-shaped grinding brush 43 on the outer wall thereof will clean the scale and impurities on the outer surface of the ball valve core 36;

[0046] By such arrangement, during the use of the ball valve, by calculating the risk value of the operating state of the first drive component when the ball valve is switched, and by comparing the risk value of the operating state of the first drive component with the preset risk value threshold of the operating state through the data analysis module, the operating state of the ball valve can be analyzed and judged, thereby accurately judging whether the ball valve needs to be cleaned, and when the operating state of the ball valve is poor, the scale and impurities on the outer surface of the ball valve core 36 are cleaned by the first arc-shaped grinding brush 43 as soon as possible, thereby improving the benefits of cleaning the ball valve and ensuring the normal use of the ball valve, thereby avoiding affecting the service life of the first drive component;

[0047] It should be noted that the above data acquisition process can be obtained by connecting the management end to relevant sensors, and the data acquisition methods can be completed through existing technologies and will not be described in detail here.

[0048] See also Figure 2As shown, the first driving assembly includes a first gear 32 fixedly connected to the upper end of the outer wall of the valve stem 31, a driving motor 34 is fixedly connected to the top of the mounting seat 2 and located on one side of the valve stem 31, a second gear 33 is fixedly connected to the output end of the driving motor 34, the second gear 33 is meshed and connected with the first gear 32, and a plurality of groups of temperature sensors 35 are fixedly connected to the outer wall of the driving motor 34;

[0049] Through the above technical solution, when using the ball valve, the drive motor 34 is first turned on, and the output shaft of the drive motor 34 will drive the second gear 33 to rotate. Since the second gear 33 is in a meshing state with the first gear 32, when the second gear 33 rotates, it will drive the first gear 32 and the valve stem 31 to rotate synchronously, thereby realizing the rotation of the ball valve core 36 to ensure the normal use of the ball valve. In addition, the automatic control characteristics of the drive motor 34 help to accurately change the passage and flow of the fluid medium in the pipeline. This precise control enables the electric ball valve to respond quickly and adjust the pipeline medium flow in time.

[0050] See also Figure 1 , Figure 2 As shown, the second driving member includes screw rods 41 rotatably connected to the two groups of mounting grooves 4, the connecting rod 42 is threadedly connected to the screw rod 41, and the end of the screw rod 41 is fixedly connected to the output end of the embedded motor;

[0051] Through the above technical solution, when the data analysis module determines that the operating state of the ball valve is poor, the management end will start the embedded motor, and the output shaft of the embedded motor will drive the screw rod 41 to rotate. When the screw rod 41 rotates, it will drive the connecting rod 42 on its outer wall to move in the installation groove 4 through threaded transmission. During the movement of the connecting rod 42, the first arc-shaped grinding brush 43 on its outer wall will clean the scale and impurities on the outer surface of the ball valve core 36, thereby preventing these dirt or impurities from increasing the volume of the ball valve core 36, resulting in difficulty or inability to rotate the ball valve, thereby ensuring the normal use of the ball valve.

[0052] See also Figure 3 As shown, the two groups of the first arc-shaped grinding brushes 43 are provided with connecting grooves, each of which is fixedly connected to a partition 45, and the outer walls of both sides of each partition 45 are fixedly connected to a spring 46, and one end of each spring 46 away from the partition 45 is fixedly connected to a second arc-shaped grinding brush 44, and the second arc-shaped grinding brush 44 is slidably installed in the connecting groove;

[0053] In the initial state, the spring 46 is in a compressed state, the second arc-shaped grinding brush 44 is located inside the connecting groove, and one end of the second arc-shaped grinding brush 44 outside the connecting groove contacts the inner wall of the valve body 1. When the connecting rod 42 moves under the cooperation between the embedded motor and the screw rod 41, it will gradually move toward the center of the valve core channel. During this process, the second arc-shaped grinding brush 44 will gradually move outward under the elastic restoring force of the spring 46, thereby increasing the contact area with the ball valve core 36 and improving the cleaning effect of the ball valve core 36. By such a setting, it can be ensured that during the entire cleaning process, the first arc-shaped grinding brush 43 and the second arc-shaped grinding brush 44 can contact all positions of the outer surface of the ball valve, thereby improving the cleaning effect.

[0054] It should be noted that a large number of brushes (not shown in the figure) are disposed on the outer walls of the first arc-shaped grinding brush 43 and the second arc-shaped grinding brush 44. When the second arc-shaped grinding brush 44 enters the connecting groove, the brushes may be squeezed.

[0055] The calculation process of the data processing module includes:

[0056] By formula Calculate the risk value θ of the operating state of the drive motor 34 when the ball valve is switched on and off for the i-th time i ;

[0057] Where i is the opening and closing of any ball valve, GL i is the power of the driving motor 34 when the ball valve is switched on and off for the i-th time, GL0 is the standard power of the driving motor 34 when the ball valve is switched on and off, and W i is the temperature of the ath position of the driving motor 34 when the ball valve is switched on and off for the ith time, W0 is the standard temperature of the driving motor 34 when the ball valve is switched on and off, and f A is the water quality impact function. The water quality impact function can be set based on the test fitting of the impact of water quality parameters on the risk value of the motor operation state. i is the water quality parameter when the ball valve is switched on and off for the i-th time, f L To define a function, if SJ i -SJ0>0,f L =SJ i -SJ0, if SJ i -SJ0<0, then f L =0, SJ i is the time used for the i-th opening and closing of the ball valve, SJ0 is the standard time used for opening and closing the ball valve, X1 and X2 are weight coefficients, which can be set according to experience fitting, SJ1 is SJ i The standard value of the above standard value can be selected and set according to the allowable error in the empirical data;

[0058] Through the above technical solution, this embodiment provides the risk value θ of the operating state of the drive motor 34 when the ball valve is switched on and off for the i-th time. i , can be obtained by formula It is calculated that, obviously, when the ball valve is switched on and off for the i-th time, the higher the operating temperature and power of the drive motor 34, and the longer the time of switching the ball valve, the higher the risk value of the operating state of the drive motor 34, indicating that the valve stem 31 and the ball valve core 36 are difficult to rotate at this time, and a large amount of scale may be attached to the outer surface of the ball valve core 36. These dirt or impurities will increase the volume of the ball valve core 36, and need to be cleaned. On the contrary, when the operating temperature and power of the drive motor 34 are lower, and the time of switching the ball valve is shorter, the risk value of the operating state of the drive motor 34 is lower, indicating that the valve stem 31 and the ball valve core 36 are easy to rotate at this time;

[0059] Through such a setting, the operating state of the ball valve can be determined according to the risk value of the operating state of the driving motor 34 when the ball valve is switched on and off for the i-th time, and whether scale or impurities are attached to the outer surface of the ball valve core 36 can be determined according to the operating state, and whether the ball valve core 36 should be cleaned can be decided according to the judgment result, thereby improving the benefits of cleaning the ball valve and ensuring the normal use of the ball valve, thereby avoiding affecting the service life of the driving motor 34.

[0060] The process of analysis and judgment by the data analysis module includes:

[0061] By calculating the risk value θ of the operating state of the driving motor 34 when the ball valve is switched for the i-th time i and the preset risk value θ of the drive motor 34 A Make a comparison;

[0062] If θ i ≤θ A , judging that the risk value of the operating state of the driving motor 34 when the ball valve is switched on and off for the i-th time is low, and judging that the operating state of the ball valve is good when the ball valve is switched on and off for the i-th time, and estimating the subsequent operating state of the subsequent ball valve by calculating the discrete coefficient of the risk value of the operating state of the driving motor 34;

[0063] If θ i >θ A , judging that the risk value of the operating state of the driving motor 34 is high when the ball valve is switched on and off for the i-th time, judging that the operating state of the ball valve is poor when the ball valve is switched on and off for the i-th time, and cleaning the ball valve core 36 by the first arc-shaped grinding brush 43 and the second arc-shaped grinding brush 44;

[0064] Through the above technical solution, this embodiment calculates the risk value θ of the operating state of the driving motor 34 when the ball valve is switched for the i-th time. i and the preset risk value θ of the drive motor 34 A For comparison, if θ i ≤θA , it is judged that the risk value of the operating state of the driving motor 34 is low when the ball valve is switched on and off for the i-th time, and it is judged that the operating state of the ball valve is good when the ball valve is switched on and off for the i-th time, and there is no scale and impurities attached to the outer surface of the ball valve core 36. If θ i >θ A , it is judged that the risk value of the operating state of the driving motor 34 is high when the ball valve is switched on and off for the i-th time, and it is judged that the operating state of the ball valve is poor when the ball valve is switched on and off for the i-th time. At this time, there may be a large amount of scale and impurities on the outer surface of the ball valve core 36. Then, the embedded motor is driven by the management end, and the connecting rod 42 is driven to move in the installation groove 4 under the cooperation of the embedded motor and the screw rod 41, so as to realize the cleaning of the ball valve core 36 by the first arc-shaped grinding brush 43 and the second arc-shaped grinding brush 44. At this time, the two sets of the first arc-shaped grinding brush 43 and the second arc-shaped grinding brush 44 will clean the outer surfaces on both sides of the ball valve core 36, so as to remove the scale and impurities on its outer surface, and ensure the normal use of the subsequent ball valve;

[0065] Through this judgment method, the operating state of the ball valve can be accurately judged, so as to make an accurate judgment on whether the ball valve core 36 needs to be cleaned at the first time, and when the operating state of the ball valve is poor, the scale and impurities on the outer surface of the ball valve core 36 are cleaned by the first arc-shaped grinding brush 43 at the first time, thereby improving the benefits of cleaning the ball valve and ensuring the normal use of the ball valve, thereby avoiding affecting the service life of the first drive component.

[0066] The calculation process of the data processing module also includes:

[0067] By formula Calculate and obtain the coefficient of dispersion S of the risk value of the drive motor 34;

[0068] Among them, n is the total number of times the ball valve is opened and closed, is θ i The average value, f c is the adjustment coefficient comparison table function. The above adjustment coefficient comparison table function can be based on The influence of the value range of on the risk value is obtained based on the test data. is θ i The maximum value of

[0069] Through the above technical solution, this embodiment provides a discrete coefficient S of the risk value of the drive motor 34, which can be expressed by the formula It is calculated that, obviously, when the dispersion coefficient of the risk value of the drive motor 34 is higher, it means that the risk value fluctuation of the drive motor 34 is larger, then the operation state of the ball valve may deteriorate in the future. On the contrary, when the dispersion coefficient of the risk value of the drive motor 34 is lower, it means that the risk value fluctuation of the drive motor 34 is smaller, then the operation state of the ball valve will be relatively stable in the future and can be used normally.

[0070] The process of analysis and judgment by the data analysis module further includes:

[0071] By comparing the coefficient of variation S of the risk value of the drive motor 34 with the preset coefficient of variation threshold S1 of the risk value of the drive motor 34;

[0072] If S < S1, it is judged that the fluctuation state of the risk value of the drive motor 34 is small;

[0073] Otherwise, it is judged that the fluctuation state of the risk value of the drive motor 34 is large;

[0074] Through the above technical solution, in this embodiment, by comparing the coefficient of variation S of the risk value of the drive motor 34 with the preset coefficient of variation threshold S1 of the risk value of the drive motor 34, if S < S1, it is judged that the fluctuation state of the risk value of the drive motor 34 is small, which indicates that the future operating state of the ball valve is relatively stable and can be used normally. Otherwise, it is judged that the fluctuation state of the risk value of the drive motor 34 is large, which indicates that the future operating state of the ball valve may deteriorate. By setting like this, the future operating state of the ball valve can be analyzed, so as to give an early warning in advance. And by calculating the risk value of the operating state of the drive motor 34, the operating state of the ball valve can be monitored in real time. When the operating state of the ball valve is poor, the scale and impurities on the outer surface of the ball valve spool 36 are cleaned by the first arc-shaped grinding brush 43 in the first time, which improves the benefit of cleaning the ball valve and ensures the normal use of the ball valve, thereby avoiding affecting the service life of the first driving component.
