Description

Technical Field

[0001] This invention belongs to the field of valves, specifically relating to a pipeline valve control mechanism adapted to digital twins in water treatment plants. Background Technology

[0002] In the operation and maintenance of pipeline networks in oil and gas gathering and transportation, chemical production, urban heating, water supply and other plants and stations, pipeline valves are the core components for controlling the transport of media, regulating pipeline pressure and ensuring the safe operation of the pipeline network.

[0003] As the construction of smart plants and stations progresses, digital twin technology is gradually being applied to the overall management and control of plant and station pipeline networks, requiring physical valves and digital twin models to be synchronized in real time, linked precisely, and remotely intelligently controlled.

[0004] However, most existing pipeline valve control mechanisms are independent electric or pneumatic actuators, which can only perform simple opening and closing and fixed opening degree adjustment actions on the valves. They lack a dedicated adapter interface with the plant digital twin system. The operating condition data such as the opening degree, medium pressure, and temperature of the pipeline valves cannot be synchronized to the twin model in real time, and there is a time delay deviation between the digital twin image and the physical entity.

[0005] This application proposes a pipeline valve control mechanism adapted to a digital twin for water treatment plants, which improves upon the aforementioned deficiencies. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pipeline valve control mechanism that is adapted to digital twins in water treatment plants and can solve the problems of delay and matching deviation of twin data in the prior art.

The inlet pipe and outlet pipe are connected to both ends of the valve body, respectively. The digital twin acquisition unit is installed on the valve body, and the intelligent control unit is installed on the top of the valve body. The digital twin acquisition unit and the intelligent control unit are electrically connected.

[0009] In one specific implementation scheme, the intelligent control unit includes a protective housing, a main control board, a signal conditioning circuit, a servo motor, a connecting plate, and a turntable. The bottom of the protective housing is mounted on the valve body, and the main control board, the signal conditioning circuit, and the servo motor are mounted on the top of the inner wall of the protective housing. The output end of the servo motor is connected to the connecting plate, and the bottom of the connecting plate is connected to the turntable.

[0011] In one specific implementation scheme, the digital twin acquisition unit includes a differential pressure sensor, a docking seat, a valve body temperature sensing group, and a valve body docking seat. Both ends of the differential pressure sensor are connected to docking seats. The two sets of docking seats are threadedly connected to the outer walls of the inlet and outlet pipes respectively by means of threaded locking and external sealing gaskets. The two sets of detection ends of the differential pressure sensor pass through the docking seats and extend into the interior of the inlet and outlet pipes. The valve body temperature sensing group is located directly above the differential pressure sensor. The valve body temperature sensing group consists of two symmetrical valve body docking seats.

[0012] In one specific implementation scheme, the two valve body mating seats are arc-shaped fitting seats, with the curvature completely fitting the curvature of the outer wall of the valve body, and a valve body temperature sensor is embedded in the inner wall and attached to the outer wall of the valve body by thermally conductive silicone.

[0015] In one specific implementation scheme, a flow intelligent control device is installed on the inner wall of the outlet pipe, and the flow intelligent control device is located at the connection port between the outlet pipe and the valve body.

[0016] In one specific implementation scheme, the intelligent flow control device includes a mounting frame, throttling vanes, a flow guide core, and a central shaft.

Several throttling vanes are arranged in a ring between the central shaft and the mounting frame. Several throttling vanes are rotatably engaged with the central shaft. A flow guide core is rotatably engaged at the center of the central shaft through a bearing.

[0017] In one specific implementation scheme, the outer wall of the mounting frame includes a micro motor, a gear, a semi-circular toothed block, a swing groove, a limiting post, a swing block, a rotating shaft, a connecting rod, and a collar. The micro motor is mounted on the inner wall of the mounting frame and is electrically connected to the intelligent control unit. The output end of the micro motor is connected to the gear. The top of the gear meshes with a semi-circular toothed block. A swing groove is formed on the body of the semi-circular toothed block. A limiting post is provided inside the swing groove. The limiting post is mounted on the mounting frame. A swing block is fixed to the top of the semi-circular toothed block. A rotating shaft is connected to one side of the swing block. A connecting rod is rotatably engaged on the top of the swing block. The other end of the connecting rod is connected to the collar.

[0018] In one specific implementation scheme, the limiting post can limit the left and right rotation of the swing groove.

[0019] In one specific implementation scheme, the swing block, rotating shaft and connecting rod are arranged in several arrays, and their positions correspond one-to-one with the positions of several sets of throttling blades. Several of the rotating shafts pass through the mounting frame and are connected to the throttling blades.

A scraper strip is provided between the universal groove and the sluice. The scraper strip and the universal groove are connected by a universal ball, and the other end of the scraper strip is built into the sluice.

[0022] In one specific implementation scheme, the micropores are distributed in a gradient pattern with denser pores upstream and sparser pores downstream to achieve step-by-step flow diversion and pressure relief.

[0025] In one specific implementation scheme, the guide core is equipped with a double helix, which rotates on the central shaft via bearings.

[0026] According to the technical solution proposed above, the pipeline valve control mechanism adapted to a digital twin in a water treatment plant has the following beneficial effects:

[0027] (1) The present invention sets up a digital twin acquisition unit on the valve body, and uses a differential pressure sensor and a valve body temperature sensor group to collect the medium pressure difference at both ends of the valve body and the working temperature of the valve body in real time. The signal conditioning circuit removes interference signals and completes the standardization of the signal. Then, the main control board generates a standard data frame adapted to the digital twin system and transmits it synchronously to the external digital twin system computer control module. This provides a complete data source for the mirror synchronization of the digital twin model, realizes the accurate matching between the valve working condition and the digital twin model, and solves the problems of twin data delay and matching deviation in the prior art.

[0028] (2) By controlling the adjustment of the valve stem and valve core on the valve body and the intelligent control unit, the present invention can intelligently control the lifting of the valve stem and valve core according to the data collected by the digital twin acquisition unit, thereby controlling the flow rate of the plant valve. The adjustment response is fast, no manual rotation of the turntable is required for adjustment, and the flow error is small.

[0029] (3) This invention adds a flow intelligent control device to the outlet pipe of the valve and uses an intelligent control unit to intelligently control the flip angle of several throttling blades, thereby precisely controlling the flow rate inside the valve pipe. In conjunction with the valve stem, it achieves the division of labor and cooperation between the large opening of the valve stem for coarse adjustment and the flow intelligent control device for fine adjustment, thus solving the problem of coarse valve flow regulation and large fluctuations.

[0030] (4) By adding a scraper strip to the throttling blade, the present invention can swing synchronously with the rotation of the throttling blade to clean and scrape the impurities on the edge of the throttling blade, ensuring that the sealing surfaces between two adjacent sets of throttling blades are free of foreign objects, and avoiding the situation where impurities adhere and cause leakage.

[0031] (5) The present invention has a number of micro-holes densely distributed on the flow-facing surface of the throttling blade. The micro-holes are distributed in a gradient manner with denser holes upstream and sparser holes downstream, so as to achieve step-by-step flow diversion and pressure relief. A small part of the high-pressure fluid in the medium inside the valve will flow into the micro-holes and be divided into micro-flow bundles. The micro-flow bundles dissipate energy and reduce noise in the cavity of the micro-holes and then slowly seep out, which can significantly reduce fluid turbulence noise and vibration.

Detailed Implementation

[0047] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0048] Example 1: Please refer to Figures 1-6 The specific embodiments of the present invention are as follows:

[0049] The pipeline valve control mechanism adapted to the digital twin in the water treatment plant includes a valve body 1, an inlet pipe 2, an outlet pipe 3, a digital twin acquisition unit 4, and an intelligent control unit 5. The two ends of the valve body 1 are respectively connected to the inlet pipe 2 and the outlet pipe 3, which can transmit the flow. The digital twin acquisition unit 4 is installed on the valve body 1, and the intelligent control unit 5 is installed on the top of the valve body 1. The digital twin acquisition unit 4 and the intelligent control unit 5 are electrically connected. The intelligent control unit 5 can control the operation of the digital twin acquisition unit 4 and transmit the acquired data.

[0050] Please see Figures 2-3 The intelligent control unit 5 includes a protective housing 51, a main control board 52, a signal conditioning circuit 53, a servo motor 54, a connecting plate 55, and a turntable 56. The bottom of the protective housing 51 is mounted on the valve body 1. The main control board 52, the signal conditioning circuit 53, and the servo motor 54 are mounted on the top of the inner wall of the protective housing 51. The output end of the servo motor 54 is connected to the connecting plate 55 and can drive the connecting plate 55 to rotate in both directions. The bottom of the connecting plate 55 is connected to the turntable 56.

[0051] Please see Figure 3 The valve body 1 is provided with a valve stem 11 and a valve core 12 inside. The top of the valve stem 11 is threaded to the turntable 56 through an external thread, and the bottom of the valve stem 11 is equipped with the valve core 12.

[0052] The servo motor 54 drives the connecting plate 55 to rotate. The rotation of the connecting plate 55 drives the bottom turntable 56 to rotate synchronously in both directions, thereby driving the valve stem 11 and the valve core 12 at the bottom of the valve stem 11, which are threadedly connected to the turntable 56, to move up and down, thus controlling the flow rate inside the valve.

[0053] Please see Figure 4The digital twin acquisition unit 4 includes a differential pressure sensor 41, a docking seat 42, a valve body temperature sensing group 43, and a valve body docking seat 44. Both ends of the differential pressure sensor 41 are connected to the docking seats 42. The two sets of docking seats 42 are threadedly connected to the outer walls of the inlet pipe 2 and the outlet pipe 3 respectively by means of threaded locking and external sealing gaskets. The two sets of detection ends of the differential pressure sensor 41 pass through the docking seats 42 and extend into the interior of the inlet pipe 2 and the outlet pipe 3, which can detect the pressure difference of the inlet and outlet media at both ends of the pipe. The valve body temperature sensing group 43 is located directly above the differential pressure sensor 41. The valve body temperature sensing group 43 is composed of two symmetrical valve body docking seats 44.

[0054] Please see Figures 4-5 The two valve body docking seats 44 are arc-shaped fitting seats, and the curvature is completely fitted with the curvature of the outer wall of the valve body 1. The inner wall is embedded with a valve body temperature sensor, which is attached to the outer wall of the valve body 1 by thermally conductive silicone, which can isolate the interference of external temperature and ensure the accuracy of temperature measurement.

[0055] Please see Figure 5 A magnetic block 441 is installed on the side wall of the valve body docking seat 44, and the magnetic poles of the magnetic blocks 441 on the side walls of the two sets of valve body docking seats 44 are opposite. By means of the attraction between opposite poles of the magnetic blocks 441, the two sets of valve body docking seats 44 can be attracted and installed on the outer wall of the valve body 1 to collect the working temperature of the valve body 1.

[0056] Please see Figures 4-6 The differential pressure sensor 41, valve body temperature sensing group 43, and servo motor 54 are all electrically connected to the signal conditioning circuit 53 via electrical signals. The signal conditioning circuit 53 is electrically connected to the main control board 52. Each acquisition component is equipped with a high-precision acquisition chip, which, together with the signal conditioning circuit 53, can perform noise filtering, signal amplification, and analog-to-digital conversion to ensure accurate and stable data acquisition.

[0057] The differential pressure sensor 41 and the valve body temperature sensing group 43 collect the medium pressure difference and valve body operating temperature at both ends of the valve body 1 in real time. First, the signal conditioning circuit 53 removes interference signals and completes the signal standardization processing. Then, the main control board 52 packages and generates standard data frames adapted to the digital twin system, which are synchronously transmitted to the external computer control module. This provides a complete data source for the mirror synchronization of the digital twin model, and realizes the precise coordination between the valve operating conditions and the digital twin model.

[0058] Example 2: Please refer to Figures 7-13 The specific embodiments of the present invention are as follows:

[0059] Please see Figure 7The inner wall of the outlet pipe 3 is equipped with a flow intelligent control device 6, which is located at the connection between the outlet pipe 3 and the valve body 1, and can accurately control the flow rate.

[0060] Please see Figures 8-10 The intelligent flow control device 6 includes a mounting frame 61, throttling vanes 62, a flow guide core 63, and a central shaft 64. The outer wall of the mounting frame 61 is connected to the inner wall of the outlet pipe 3. The central shaft 64 is located at the center of the mounting frame 61. Several throttling vanes 62 are arranged in a ring between the central shaft 64 and the mounting frame 61. The several throttling vanes 62 are rotatably engaged with the central shaft 64. The flow guide core 63 is rotatably engaged with the center of the central shaft 64 through a bearing.

[0061] Please see Figure 9 The outer wall of the mounting frame 61 includes a micro motor 21, a gear 22, a semi-circular toothed block 23, a swing groove 24, a limiting post 25, a swing block 26, a rotating shaft 27, a connecting rod 28, and a collar 29. The micro motor 21 is mounted on the inner wall of the mounting frame 61 and is electrically connected to the intelligent control unit 5. The output end of the micro motor 21 is connected to the gear 22 and can drive the gear 22 to rotate in both directions. The top of the gear 22 is meshed with the semi-circular toothed block 23. The body of the semi-circular toothed block 23 has a swing groove 24. The swing groove 24 has a limiting post 25 inside. The limiting post 25 is mounted on the mounting frame 61. The top of the semi-circular toothed block 23 is fixed with the swing block 26. One side of the swing block 26 is connected to the rotating shaft 27. The top of the swing block 26 is rotatably engaged with the connecting rod 28. The other end of the connecting rod 28 is connected to the collar 29.

[0062] Please see Figure 9 The limiting post 25 can limit the left and right rotation of the swing groove 24, and stop when the swing groove 24 slides to the edge and contacts the limiting post 25.

[0063] Please see Figure 9 The oscillating block 26, the rotating shaft 27 and the connecting rod 28 are arranged in several arrays, and their positions correspond one-to-one with the positions of several sets of throttling blades 62. Several rotating shafts 27 pass through the mounting frame 61 and are connected to the throttling blades 62. The throttling blades 62 can rotate synchronously with the rotation of the rotating shaft 27.

[0064] Please see Figure 9 Several connecting rods 28 are connected to collars 29, and the collars 29 connect the several connecting rods 28 to form a linked whole;

[0065] The micro motor 21 drives the gear 22 to rotate in both directions. Through the gear meshing between the gear 22 and the semi-circular tooth block 23, the semi-circular tooth block 23 and the swing block 26 connected to the semi-circular tooth block 23 can be driven to rotate synchronously on the limit post 25 in the left and right directions. It can also drive the rotating shaft 27 connected to the swing block 26 and the throttling vane 62 located on the rotating shaft 27 to rotate synchronously, thereby controlling the opening angle of the throttling vane 62 and enabling fine regulation of the flow rate.

[0066] Please see Figures 10-11 The throttling vane 62 includes micro-holes 621, a sliding groove 622, a universal groove 623, and a scraper strip 624. The flow-facing surface of the throttling vane 62 has several micro-holes 621. The flow-facing surface of the throttling vane 62 has a sliding groove 622 and a universal groove 623. A scraper strip 624 is provided between the universal groove 623 and the sliding groove 622. The scraper strip 624 and the universal groove 623 are connected by a universal ball, so that one end of the scraper strip 624 can rotate universally in the universal groove 623, and the other end of the scraper strip 624 is built into the sliding groove 622 and can only slide inside the sliding groove 622.

[0067] Please see Figure 11 The micro-holes 621 are distributed in a gradient manner with denser ones upstream and sparser ones downstream to achieve step-by-step flow diversion and pressure relief. When the medium inside the valve body 1 flows and impacts the throttling vane 62, most of the medium passes through the main flow through hole, while a small portion of high-pressure fluid rushes into the micro-holes 621 on the flow-facing surface, where it is divided into micro-flow bundles to achieve multi-stage buffer pressure relief. The micro-flow bundles dissipate energy and reduce noise in the cavity of the micro-holes 621 before slowly seeping out, which can significantly reduce fluid turbulence noise and vibration.

[0068] Please see Figures 11-12 The scraper 624 has a tapered cross section on the side near the edge of the throttling vane 62. When the scraper 624 rotates with the throttling vane 62, it swings inside the universal groove 623. The sliding groove 622 limits its movement, so that the scraper 624 can only swing within the sliding groove 622. This allows it to clean and scrape the impurities on the edge of the throttling vane 62, ensuring that the sealing surfaces between two adjacent sets of throttling vanes 62 are free of foreign objects and preventing impurities from adhering and causing leakage.

[0069] Please see Figure 12 The throttling blade 62 has a honeycomb layer 625 inside its body. The honeycomb layer 625 and the throttling blade 62 are an integrated structure, which can ensure the overall strength of the throttling blade 62, and can form a closed buffer pressure reduction cavity by means of the internal honeycomb structure.

[0070] Please see Figure 13The flow guide core 63 is equipped with a double helical blade 631, which rotates on the central shaft 64 through the bearing. When the fluid inside the pipe flows through the flow guide core 63, it will impact the double helical blade 631, thereby driving the flow guide core 63 to rotate on the bearing. The rotation will generate a vortex flow, which will directly carry away and discharge the sediment, entangled fibers and other impurities deposited in the center of the pipe, thus preventing impurities from accumulating on the flow intelligent control device 6.

[0071] Based on the above embodiments, the specific working principle is as follows:

[0072] When the intelligent control unit 5 in Embodiment 1 controls the valve stem 11 and valve core 12 to rise and fall, thereby adjusting the flow rate in the valve body 1, the intelligent control unit 5 continues to drive the micro motor 21 to drive the gear 22 to rotate in both directions. With the meshing of the gear 22 and the semi-circular tooth block 23, the semi-circular tooth block 23 and the swing block 26 connected to the semi-circular tooth block 23 can be driven to rotate synchronously in the left and right directions on the limit post 25, and the rotating shaft 27 and the throttling vane 62 on the rotating shaft 27 can be driven to rotate synchronously, thereby controlling the opening angle of the throttling vane 62 and finely regulating the flow rate.

[0073] When the fluid flows through the guide core 63, it impacts the twin helical blades 631, causing the guide core 63 to rotate on the bearing and generate a vortex flow. This vortex flow directly carries away and discharges the sediment, tangled fibers, and other impurities deposited in the center of the pipe, preventing impurities from accumulating on the intelligent flow control device 6.

The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
