Description

Technical Field

[0001] This invention relates to the field of industrial data acquisition and early warning, specifically to an industrial valve operation and maintenance data acquisition system and a monitoring and early warning system. Background Technology

[0002] Industrial valves are essential accessories for controlling the flow of media in industrial pipelines. They can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. A valve consists of three main parts: the valve body, the valve stem opening and closing mechanism, and the valve cover. Its functions include cutting off or opening the flow of fluid within a pipe, regulating the flow rate and velocity, creating a significant pressure drop after the fluid passes through the valve, and maintaining a certain pressure. Therefore, in industrial production, a large number of industrial valves are used in a system to support the operation of the entire system. For example, in the petrochemical industry, such as oil refineries and chemical plants, there are many harsh operating conditions and environments. The operating media include high temperature, high pressure, high solid content, multiphase media, as well as many hazardous gases, volatile gases, and flammable and explosive gases. These can not only cause valve failures, but once pipeline or valve leaks occur, especially leaks of hazardous gases, they may directly affect the life safety of workers and even cause other incalculable harm and consequences. Therefore, it is necessary to collect industrial valve operation and maintenance data for users to monitor. However, the current method of using personnel for inspection not only poses a threat to the life and health of the inspection personnel, but also has no early warning function. Therefore, it is very important to obtain an industrial valve operation and maintenance data acquisition system and monitoring and early warning system that overcomes the above defects. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, on the one hand, the present invention provides an industrial valve operation and maintenance data acquisition system, including at least one industrial valve body, and further including a first pressure detection element and a second pressure detection element configured on the front pipeline and the rear pipeline of the industrial valve, and a first temperature detection element and a second temperature detection element configured on the front pipeline and the rear pipeline of the industrial valve.

[0004] The industrial valve body includes a nameplate containing an RFID electronic tag. The electronic tag stores the valve body's serial number, location, model, and size information. It also includes a rewritable memory containing the valve's operating time data, maintenance data, and opening / closing status change data. The valve stem of the industrial valve body is equipped with a drive measuring device that measures the valve stem's rotation angle or axial movement distance.

[0005] It also includes a cloud database, and the data detected by the drive measuring device, the first pressure sensor, the second pressure sensor, the first temperature sensor, and the second temperature sensor, as well as the data in the rewritable memory, are transmitted to the cloud database.

[0006] As a preferred embodiment, the cloud database is equipped with a timing device and also includes a storage database. The timing device will periodically clear or transfer the data in the cloud database to the storage database.

[0007] With the above technical solution, users can choose to clear or retain historical data, and the time interval can be selected as needed.

[0008] There are two types of driving and measuring devices. When the valve stem is controlled by rotary transmission, such as a ball valve, the driving and measuring device includes an encoder. The output shaft of the encoder is fixedly connected to the valve stem, or a first gear is fixed to the outside of the valve stem, and a second gear is fixed on the output shaft of the encoder. The first gear and the second gear mesh.

[0009] Through the above technical solution, the valve stem rotates, which in turn drives the output shaft of the encoder to rotate, thereby determining the rotation angle of the valve stem. Based on the rotation angle of the valve stem, the opening size of the valve is determined, that is, by using the pressure difference between the first pressure detection element and the second pressure detection element.

[0010] When the valve stem of an industrial valve body rotates and then moves axially to control the valve's operation, such as a threaded gate valve, the driving measuring device includes a fixed bracket fixed to the inner wall of the industrial valve body. The fixed bracket has a first through hole through which the valve stem passes. The valve stem has evenly spaced arc-shaped tracks. The fixed bracket has a second through hole through which resistance strips pass. A movable component is fixed to the resistance strip, and the end of the movable component is within the arc-shaped track. A first wire is led out from one end of the resistance strip, and a second wire is led out from one of the legs of the fixed bracket.

[0011] As a preferred embodiment, a bearing is provided between the valve stem and the first through hole to reduce friction between them and facilitate valve stem operation.

[0012] As a preferred embodiment, one of the support legs has a channel at its top that communicates with the second through hole. A pin is fixed on the inner wall of the channel. The second wire is electrically connected to the pin. The second end of the pin is connected to a contact block via a spring. The contact block abuts against the surface of the resistor strip.

[0013] With the above technical solution, the contact block abuts against the surface of the resistor strip, which can achieve stable contact between the two. This ensures that when the valve stem rotates, it drives the moving part to move on the arc track, which in turn drives the resistor strip to move. The resistance value between the first wire and the second wire will change, so as to determine the size of the valve opening controlled by the valve stem. The judgment is then made by the pressure difference between the first pressure detection element and the second pressure detection element.

[0014] On the other hand, the present invention provides a monitoring and early warning system, including the aforementioned industrial valve operation and maintenance data acquisition system, and further including a data processing device. The data detected by the drive measuring device, the first pressure detection element, the second pressure detection element, the first temperature detection element, and the second temperature detection element are directly transmitted to the data processing device, or the data processing device retrieves the aforementioned data from a cloud database and / or a storage database. The system also includes a mobile terminal, which retrieves the data detected by the drive measuring device, the first pressure detection element, the second pressure detection element, the first temperature detection element, and the second temperature detection element, or the data from the cloud database and / or the storage database in real time. When the data detected by the drive measuring device, the first pressure detection element, the second pressure detection element, the first temperature detection element, and the second temperature detection element exceed a preset threshold in the data processing device, the data processing device sends an early warning message to the mobile terminal.

[0015] As a preferred embodiment, the data detected by the driving measuring device, the first pressure sensor, and the first temperature sensor are dynamically recorded in a cloud database. The dynamic adjustment data made by the second pressure sensor and the second temperature sensor after receiving the data transmitted by the first pressure sensor and the first temperature sensor are also recorded in the cloud database. The data processing device makes a prediction based on the dynamic data detected by the driving measuring device, the first pressure sensor, and the first temperature sensor and the data recorded in the cloud database, and sends the pre-tightening information to the terminal.

[0016] As a preferred embodiment, the warning information includes the number, location, model, and size information of the RFID electronic tag in the nameplate of the industrial valve body, as well as pressure and / or temperature information, so that managers or users can accurately locate the valve and prevent accidents from occurring.

[0017] The encoder's rotational angular velocity and the rate of change of resistance can also be transmitted to a cloud database and a data processing device. The data processing device determines whether to issue a warning signal by comparing it with a large amount of historical data.

[0018] Compared with the prior art, the advantages of the present invention are: the system structure of the present invention is simple, data acquisition is convenient, the driving measurement device selects encoder or resistance value measurement to collect the working data of valve stem in the valve according to the working principle of the valve stem of the industrial valve body, and the data processing device makes early warning judgments through a large amount of historical dynamic data.

[0032] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention.

[0033] Referring to the accompanying drawings, the present invention adopts the following technical solution: an industrial valve operation and maintenance data acquisition system, including at least one industrial valve body 1, and further including a first pressure detection element 201 and a second pressure detection element 202 configured on the front pipeline 101 and the rear pipeline 102 of the industrial valve, and a first temperature detection element 203 and a second temperature detection element 204 configured on the front pipeline 101 and the rear pipeline 102 of the industrial valve.

[0034] The industrial valve body 1 includes a nameplate 205, which contains an RFID electronic tag 2051. The electronic tag stores the number, location, model, and size information of the industrial valve body 1. It also includes a rewritable memory 206, which records the industrial valve's operating time data, maintenance data, and opening / closing status change data. The valve stem 8 of the industrial valve body 1 is equipped with a drive measuring device 200, which measures the rotation angle or axial movement distance of the valve stem 8.

[0035] It also includes a cloud database 207, through which data detected by the drive measuring device 200, the first pressure detection element 201, the second pressure detection element 202, the first temperature detection element 203, and the second temperature detection element 204, as well as data in the rewritable memory 206, are transmitted to the cloud database 207.

[0036] As a preferred embodiment, the cloud database 207 is equipped with a timing device 209 and also includes a storage database 208. The timing device 209 will periodically clear or transfer the data in the cloud database 207 to the storage database 208.

[0037] With the above technical solution, users can choose to clear or retain historical data, and the time interval can be selected as needed.

[0038] The driving measuring device 200 has two modes. When the valve stem 8 is controlled by rotary transmission, such as a ball valve, the driving measuring device 200 includes an encoder 301. The output shaft of the encoder 301 is fixedly connected to the valve stem 8, or a first gear 302 is fixed to the outside of the valve stem 8, and a second gear 303 is fixed on the output shaft of the encoder 301. The first gear 302 and the second gear 303 mesh.

[0039] Through the above technical solution, the valve stem 8 rotates, thereby driving the output shaft of the encoder 301 to rotate, and then determining the rotation angle of the valve stem 8. Based on the rotation angle of the valve stem 8, the opening size of the valve is determined, that is, by the pressure difference between the first pressure detection element 201 and the second pressure detection element 202.

[0040] When the valve stem 8 of the industrial valve body 1 rotates and moves axially to control the valve operation, such as a threaded gate valve, the driving measuring device 200 includes a fixed bracket 401 fixed to the inner wall of the industrial valve body 1. The fixed bracket 401 has a first through hole through which the valve stem 8 passes. The valve stem 8 has an evenly spaced arc-shaped track 402. The fixed bracket 401 has a second through hole through which a resistance strip 403 passes. A moving part 404 is fixed on the resistance strip 403. The end of the moving part 404 is inside the arc-shaped track 402. A first wire 405 is led out from one end of the resistance strip 403, and a second wire 406 is led out from one of the legs of the fixed bracket 401.

[0041] As a preferred embodiment, a bearing is provided between the valve stem 8 and the first through hole to reduce friction between them and facilitate the operation of the valve stem 8.

[0042] As a preferred embodiment, one of the support legs has a channel at the top that communicates with the second through hole. A pin 501 is fixed on the inner wall of the channel. The second wire 406 is electrically connected to the pin 501. The second end of the pin 501 is connected to a contact block 502 via a spring 503. The contact block 502 abuts against the surface of the resistor strip 403.

[0043] Through the above technical solution, the contact block 502 abuts against the surface of the resistor strip 403, which can achieve stable contact between the two. This ensures that when the valve stem 8 rotates, it drives the moving part 404 to move on the arc track 402, which in turn drives the resistor strip 403 to move. The resistance value between the first wire 405 and the second wire 406 will change, so as to determine the size of the valve opening controlled by the valve stem 8. The judgment is then made by the pressure difference between the first pressure detection element 201 and the second pressure detection element 202.

[0044] On the other hand, the present invention provides a monitoring and early warning system, including the above-mentioned industrial valve operation and maintenance data acquisition system, and further including a data processing device 6. The data detected by the drive measuring device 200, the first pressure detection element 201, the second pressure detection element 202, the first temperature detection element 203, and the second temperature detection element 204 are directly transmitted to the data processing device 6, or the data processing device 6 retrieves the above data from the cloud database 207 and / or the storage database 208. The system also includes a mobile terminal 7, which retrieves the data detected by the drive measuring device 200, the first pressure detection element 201, the second pressure detection element 202, the first temperature detection element 203, and the second temperature detection element 204, or the data in the cloud database 207 and / or the storage database 208 in real time. When the data detected by the drive measuring device 200, the first pressure detection element 201, the second pressure detection element 202, the first temperature detection element 203, and the second temperature detection element 204 exceeds a preset threshold in the data processing device 6, the data processing device 6 sends an early warning message to the mobile terminal 7.

[0045] As a preferred embodiment, the data detected by the drive measuring device 200, the first pressure detection element 201, and the first temperature detection element 203 are dynamically recorded in the cloud database 207. The dynamic adjustment data made by the second pressure detection element 202 and the second temperature detection element 204 after receiving the data transmitted by the first pressure detection element 201 and the first temperature detection element 203 are also recorded in the cloud database 207. The data processing device 6 makes a prediction based on the dynamic data detected by the drive measuring device 200, the first pressure detection element 201, and the first temperature detection element 203 and the data recorded in the cloud database 207, and sends the pre-tightening information to the terminal.

[0046] As a preferred embodiment, the warning information includes the number, location, model, and size information of the RFID electronic tag 2051 inside the nameplate 205 of the industrial valve body 1, as well as pressure and / or temperature information, so that managers or users can accurately locate the valve and prevent accidents from occurring.

[0047] The rotational angular velocity and resistance change rate data of encoder 301 can also be transmitted to cloud database 207 and data processing device 6. Data processing device 6 determines whether to issue a warning signal by comparing with a large amount of historical data.

[0048] Compared with the prior art, the advantages of the present invention are: the system structure of the present invention is simple, data acquisition is convenient, the driving measurement device 200 selects encoder 301 or resistance value measurement to collect the working data of valve stem 8 in the valve according to the working principle of valve stem 8 of industrial valve body 1, and the data processing device 6 makes early warning judgment through a large amount of historical dynamic data.

[0049] When this invention is put into use, one of its functions is as follows: the driving measuring device 200 transmits the motion data of the valve stem 8 to the cloud database 207 and / or the data processing device 6. The first pressure detection element 201 and the first temperature detection element 203 transmit the detection data to the cloud database 207 and / or the data processing device 6. At this time, the data detected by the second pressure detection element 202 and the second temperature detection element 204 will change due to the movement of the valve stem 8. This data is also transmitted to the cloud database 207 and / or the data processing device 6. The above dynamic data will be stored in the storage database 208 to form historical data. When the driving measuring device 200 transmits the motion data of the valve stem 8 again, the data processing device 6 will make a warning judgment based on the dynamic data difference and combined with the historical data, and transmit the information to the mobile terminal 7.

[0050] Its second function is: if the data detected by the first pressure detection element 201, the first temperature detection element 203, the second pressure detection element 202, and the second temperature detection element 204 exceed the threshold due to damage to the industrial valve body 1 or other factors, then the warning information will be directly transmitted to the mobile terminal 7.
