Description

Technical Field

[0001] The present invention relates to the field of valves, and specifically to an Internet of Things intelligent valve positioner. Background Art

[0002] A valve positioner, classified by structure into a pneumatic valve positioner, an electric valve positioner, and an intelligent valve positioner, is a main accessory of a control valve and is usually used in conjunction with a pneumatic control valve. It receives the output signal of a regulator and then uses its output signal to control the pneumatic control valve. After the control valve acts, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position condition is transmitted to the upper-level system through an electric signal.

[0003] However, for the current intelligent valve positioner, since it does not require human control during use, which is an easily overlooked point, the positioner is extremely vulnerable to water and moisture erosion during use and is damaged. At the same time, its outer shell will also become loose. Once it becomes loose, it is easier for water, moisture, and dust to enter the interior of the positioner, thus greatly reducing the service life of the positioner. And when it becomes loose, it is already too late when the problem is discovered, and the positioner needs to be replaced, resulting in a relatively high cost. Summary of the Invention

[0004] The purpose of the present invention is to provide an Internet of Things intelligent valve positioner to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An Internet of Things intelligent valve positioner includes a positioner main body and an outer protection cover. A bottom plate is fixedly provided on the lower end surface of the outer protection cover. An inner cavity is formed between the bottom plate and the outer protection cover. The positioner main body is placed in the inner cavity and fixedly installed on the bottom plate. A signal module is fixedly installed at the upper left corner of the outer protection cover. A hard rubber block is fixedly installed at the upper left corner position in the inner cavity. The upper left corner edge of the positioner main body is embedded in the hard rubber block. The hard rubber block closely adheres to the upper end surface and the left end surface edge of the positioner main body. An inductor is provided on the upper end surface of the hard rubber block. The inductor is embedded in the outer protection cover. An induction plate is slidably arranged in the hard rubber block. The upper end surface of the induction plate abuts against the inductor.

[0006] Preferably, the locator body is composed of a front protective case located on the front side and a rear protective case located on the rear side. The front protective case and the rear protective case are provided with an arc-shaped groove at the joint line on the upper end face. The lower end face of the induction plate abuts against the joint line in the arc-shaped groove. The provided arc-shaped groove facilitates people to exert force by pinching with their fingers when disassembling the locator body. At the same time, when the locator body becomes loose, the rear protective case and the front protective case will separate, resulting in a gap at the joint line position, so that the induction plate will be inserted into the gap, and the inductor will be induced.

[0007] Preferably, the middle section of the induction plate is elastically telescopic, and the lower end of the induction plate is a triangular tip.

[0008] Preferably, a drying plate is fixedly installed in the outer protective cover. The lower end face of the drying plate is equidistantly distributed and fixedly provided with silica gel mesh bags. The lower end face of each silica gel mesh bag respectively penetrates and extends into the inner cavity, so that the water vapor generated above the locator body can be absorbed through the silica gel mesh bags, thereby ensuring the dryness of the working environment of the locator body.

[0009] Preferably, a notch strip-shaped groove with an opening forward is provided on the left side of the outer protective cover. A first connecting pipe head is provided on the left end face of the locator body, and the first connecting pipe head is embedded in the notch strip-shaped groove to form a positioning.

[0010] Preferably, a display screen is provided on the front end face of the locator body. Four buttons are equidistantly distributed at the lower side position of the display screen. Two second connecting pipe heads are provided at the right end of the locator body, and a dashboard is distributed in front of each second connecting pipe head.

[0011] Preferably, the signal module is electrically connected to the inductor. A storage unit is provided in the signal module. The storage unit stores the time point when the induction plate is inserted when the front protective case and the rear protective case become loose, and the inductor emits an induction signal. Thus, the time record in the signal module can be retrieved every once in a while to compare and analyze the flow rate, pressure, etc. at the corresponding valve position, so as to analyze the specific reason for the loosening of the locator, and then adjustments can be made to reduce the number of its loosening times.

[0012] Preferably, a warning light is fixedly installed on the upper end face of the outer protective cover. The warning light is electrically connected to the signal module. Thus, during the use of the locator, once loosening occurs and a gap appears between the front protective case and the rear protective case, the induction signal emitted by the inductor is transmitted to the signal module. The signal module analyzes and processes the induction signal, so that the warning light is activated to emit an alarm, enabling people to perform maintenance on it.

[0013] Preferably, a Bluetooth module is provided in the signal module, which can be connected to a mobile device to retrieve data, so as to facilitate workers to retrieve information for viewing during inspections or maintenance.

[0014] In summary, the beneficial effects of the present invention are as follows:

[0015] First, the present invention protects the locator by providing an outer protective cover outside the locator to prevent the intrusion of impurities and dust. At the same time, moisture absorption is provided inside to effectively ensure the working environment of the locator and prevent it from being eroded by moisture, thereby effectively increasing its service life. During use, the joint of the locator body can be continuously sensed. Once the locator body loosens during operation, the rear protective shell and the front protective shell will separate, causing a gap at the joint line. At this time, the sensing plate will insert into the gap, causing the sensor to be sensed. This can not only remind people to perform maintenance but also record the loosening time point. Then, the time records in the signal module can be retrieved at regular intervals and compared with the flow rate, pressure, etc. at the corresponding valve position for analysis, so as to analyze the specific reasons for the loosening of the locator and make adjustments to reduce the number of loosening times.

That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0024] The following combines Figures 1 - 4 to elaborate on the present invention in detail. For the sake of convenience in narration, the orientations mentioned below are defined as follows: The up-down, left-right, front-back directions mentioned below are the same as the front-back, left-right, up-down directions of the Figure 1 viewing direction, Figure 1 which is the front view of the device of the present invention, Figure 1 and the directions shown are the same as the front-back, left-right, up-down directions of the front view direction of the device of the present invention.

[0025] Please refer to Figures 1 - 4 , an embodiment provided by the present invention: An Internet of Things intelligent valve positioner, including a locator body 10 and an outer protective cover 16. The lower end surface of the outer protective cover 16 is fixedly provided with a bottom plate 11. An inner cavity 18 is formed between the bottom plate 11 and the outer protective cover 16. The locator body 10 is placed in the inner cavity 18 and fixedly installed on the bottom plate 11. A signal module 21 is fixedly installed at the upper left corner of the outer protective cover 16. A hard rubber block 24 is fixedly installed at the upper left corner position in the inner cavity 18. The upper left corner edge of the locator body 10 is embedded in the hard rubber block 24. The hard rubber block 24 closely adheres to the upper end surface and the left end surface edge of the locator body 10. A sensor 25 is provided on the upper end surface of the hard rubber block 24. The sensor 25 is embedded in the outer protective cover 16. An induction plate 27 is slidably arranged in the hard rubber block 24. The upper end surface of the induction plate 27 abuts against the sensor 25.

[0026] In addition, in one embodiment, the locator body 10 is composed of a front protective case 10a located at the front side and a rear protective case 10b located at the rear side. An arc-shaped groove 26 is provided at the joint line on the upper end face of the front protective case 10a and the rear protective case 10b. The lower end face of the induction plate 27 abuts against the joint line in the arc-shaped groove 26. The provided arc-shaped groove 26 facilitates people to exert force by pinching with their fingers when disassembling the locator body 10. At the same time, when the locator body 10 becomes loose, the rear protective case 10b and the front protective case 10a will separate, causing a gap at the joint line position, so that the induction plate 27 will be inserted into the gap, and the inductor 25 will be induced.

[0027] In addition, in one embodiment, the middle section of the induction plate 27 is elastically telescopic, and the lower end of the induction plate 27 is a triangular tip.

[0028] In addition, in one embodiment, a drying plate 19 is fixedly installed in the outer protective cover 16. Silica gel mesh bags 20 are fixedly arranged at equal intervals on the lower end face of the drying plate 19. The lower end face of each silica gel mesh bag 20 respectively penetrates and extends into the inner cavity 18, so that the water vapor generated above the locator body 10 can be absorbed through the silica gel mesh bags 20, thereby ensuring the dryness of the working environment of the locator body 10.

[0029] In addition, in one embodiment, a notch strip-shaped groove 22 with an opening forward is provided on the left side of the outer protective cover 16. A first connecting pipe head 23 is provided on the left end face of the locator body 10. The first connecting pipe head 23 is embedded in the notch strip-shaped groove 22 to form a positioning.

[0030] In addition, in one embodiment, a display screen 12 is provided on the front end face of the locator body 10. Four buttons 13 are provided at equal intervals below the display screen 12. Two second connecting pipe heads 15 are provided at the right end of the locator body 10. A dashboard 14 is provided in front of each second connecting pipe head 15.

[0031] In addition, in one embodiment, the signal module 21 is electrically connected to the inductor 25. A storage unit is provided in the signal module 21. The storage unit stores the time point when the induction plate 27 is inserted and the inductor 25 emits an induction signal when the front protective case 10a and the rear protective case 10b become loose. Thus, the time records in the signal module 21 can be retrieved every once in a while to compare and analyze the flow rate, pressure, etc. at the corresponding valve position, so as to analyze the specific reason for the loosening of the locator, and thus adjustments can be made to reduce the number of its loosening times.

[0032] In addition, in one embodiment, a warning light 17 is fixedly installed on the upper end surface of the outer protective cover 16. The warning light 17 is electrically connected to the signal module 21. Thus, during the use of the locator, once loosening occurs and a gap appears between the front protective case 10a and the rear protective case 10b, the induction signal emitted by the inductor 25 is transmitted to the signal module 21. The signal module 21 analyzes and processes the induction signal, thereby activating the warning light 17 to emit an alarm, enabling people to perform maintenance on it.

[0033] In addition, in one embodiment, a Bluetooth module is provided in the signal module 21, which can be connected to a mobile device for data retrieval, thereby facilitating workers to retrieve information for viewing during inspections or maintenance.

[0034] First, connect the first connecting pipe head 23 with the corresponding external connecting pipe, and at the same time connect the second connecting pipe head 15 with the corresponding external connecting pipe respectively. After the installation is completed, obtain the corresponding data through the display screen 12 and the two instrument panels 14. When the locator is working, water vapor is very likely to be generated around. At this time, the drying plate 19 and the silica gel mesh bag 20 arranged on the upper side absorb the generated water vapor, so as to ensure the dryness of the working environment of the locator body 10, thereby avoiding the erosion of the locator. The first connecting pipe head 23 is embedded in the notch strip-shaped groove 22, and the upper and lower ends of the notch on the right side of the outer protection cover 16 abut against the locator body 10 to form a certain positioning and fixing. The hard rubber block 24 in the upper left corner wraps the locator body 10, so that part of the vibration generated when the locator body 10 works is absorbed, protecting the locator to a certain extent. At the same time, when the locator body 10 of the locator becomes loose, the rear protection shell 10b and the front protection shell 10a will separate, causing a gap at the joint line position. As a result, the induction plate 27 will be inserted into the gap, causing the inductor 25 to be induced. Then, the signal module 21 receives the induction and records it. Thus, the time record in the signal module 21 can be retrieved every once in a while to be compared and analyzed with the flow rate, pressure, etc. at the corresponding valve position, so as to analyze the specific reason for the loosening of the locator, and then adjustments can be made to reduce the number of its loosening times. At the same time, the signal module 21 analyzes and processes the induction signal, causing the warning light 17 to be activated and an alarm to be issued, so that people can maintain it. This not only effectively ensures the working environment of the locator, avoids its being eroded by water vapor, but also effectively improves its service life. At the same time, during the use process, the joint of the locator body 10 can be continuously sensed. Once the locator body 10 becomes loose during the operation of the locator, the rear protection shell 10b and the front protection shell 10a will separate, causing a gap at the joint line position. At this time, the induction plate 27 will be inserted into the gap, causing the inductor 25 to be induced. This can not only remind people to maintain it, but also record the loosening time point. Thus, the time record in the signal module 21 can be retrieved every once in a while to be compared and analyzed with the flow rate, pressure, etc. at the corresponding valve position, so as to analyze the specific reason for the loosening of the locator, and then adjustments can be made to reduce the number of its loosening times.

[0035] As described above, it is only the specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any change or replacement that comes to mind without creative work should be covered within the protection scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
