Technical Field

[0001] This utility model relates to the field of pipeline valve technology, specifically to an intelligent PLC flat gate valve. Background Technology

[0002] In the production processes of industries such as mining, metallurgy, power plants, coal, and chemicals, the storage and unloading of lumpy materials (such as ore and slag) is a crucial step. Traditional unloading valves often experience jamming during the opening and closing process due to factors such as the varying sizes and irregular shapes of the materials, as well as friction. This not only affects production efficiency but can also damage equipment and increase maintenance costs.

[0003] Traditional unloading valves mostly employ mechanical transmission or simple hydraulic control. These methods often lack intelligence and automation, making it difficult to meet the demands of modern industry for efficient and precise control. Especially in harsh working environments, such as those with high dust levels or high material hardness, the sealing performance, wear resistance, and operational stability of traditional valves face severe challenges.

[0004] Furthermore, with the continuous improvement of industrial automation, the requirements for intelligent control of key equipment such as valves are also increasing. Traditional valve control methods often rely on manual operation or simple electrical control, making it difficult to achieve functions such as remote monitoring, fault early warning, and automated adjustment. This greatly limits the flexibility and efficiency of the production process.

[0005] In response to the above problems, there is an urgent need in the market for a new type of flat gate valve that can overcome the defects of traditional valves and achieve intelligent and automated control. Utility Model Content

[0006] To address the aforementioned issues, this invention provides an intelligent PLC flat gate valve. This intelligent PLC flat gate valve controls the gate opening via a PLC program, preventing jamming during unloading and meeting the requirements of the unloading process. It plays a crucial role in the upper-level control of on-site material release and equipment maintenance.

[0026] The components represented by the various reference numerals in the diagram are:

[0027] This utility model comprises: 1. a frame, 2. a pulley block, 3. a valve plate, 4. a hydraulic cylinder, 5. a dust scraper, 6. a limit switch, and 7. a connecting rod. Detailed Implementation

[0028] like Figures 1 to 3 As shown, the new electro-hydraulic PLC flat gate valve includes a welded frame 1, a pulley block 2, a valve plate 3, a hydraulic device, a dust scraper 5, a limit switch 6, a PLC controller, and fasteners, among other components.

[0029] The welded frame 1, composed of channel steel, is used for connecting the overall base and other components. The welded assembly can then connect to other parts of the valve, such as the pulley block 2, valve plate 3, and hydraulic system.

[0030] The pulley block 2 has an internal rotating shaft connected to the welded frame 1. The pulley surfaces are mirror-finished to reduce overall friction. The function of the pulley block 2 is to support the valve plate 3 and reduce its frictional resistance during movement, making the overall valve opening and closing process smoother.

[0031] The valve plate 3 is located on the upper end of the pulley block 2 and is moved by a hydraulic device. The valve plate 3 is made of chrome-plated manganese steel, which has excellent wear resistance, erosion resistance and leakage prevention performance.

[0032] The hydraulic unit consists of two parts: a hydraulic cylinder 4 and a hydraulic power unit. The telescopic rod of the hydraulic cylinder 4 is welded to the valve plate 3 via a steel plate, enabling the hydraulic unit to move the valve plate 3. The hydraulic power unit provides hydraulic power to the hydraulic cylinder 4 and is remotely controlled and automated via a PLC controller.

[0033] The dust scraper 5 is built into the gap between the welded frame 1 and the valve plate 3 to prevent dust and debris generated during material unloading from entering the valve.

[0034] The welding frame 1 is equipped with two sets of limit switches 6, which are used to detect the opening and closing positions of the valve plate 3. The limit switches 6 are communicatively connected to the PLC controller. When the valve plate 3 reaches its designated position, the signal is transmitted to the electrical control box through the limit switches 6. The PLC controller then controls the valve accordingly based on the received signal.

[0035] The PLC controller is one of the core components of this invention, used to realize remote control and automated operation of the valve. The PLC controller can monitor the valve's operating status in real time (such as the position of valve plate 3, hydraulic device pressure, etc.) and precisely control the valve according to a preset program.

[0036] Working principle of this new electro-hydraulic PLC flat gate valve:

[0037] When the valve needs to be opened, the PLC controller receives the opening signal and controls the hydraulic station to start the hydraulic cylinder 4. The extension rod of the hydraulic cylinder 4 drives the valve plate 3 to move to the left along the pulley block 2 until the valve plate 3 is fully opened. During the opening process, the dust scraper 5 will effectively block dust and debris from entering the valve. At the same time, the limit switch 6 will monitor the position of the valve plate 3 in real time and feed the signal back to the PLC controller. When the valve plate 3 is in place, the PLC controller will control the hydraulic station to stop working and lock the position of the valve plate 3.

[0038] When the valve needs to be closed, the PLC controller receives the closing signal and controls the hydraulic station to start the hydraulic cylinder 4. The extension rod of the hydraulic cylinder 4 drives the valve plate 3 to move to the right along the pulley block 2 until the valve plate 3 is completely closed. During the closing process, if there is any obstruction (such as material blocking the channel), the pressure in the hydraulic device will increase and trigger the PLC controller. The PLC controller will automatically identify the obstruction through the program and control the hydraulic cylinder 4 to perform repeated opening and closing operations to remove the obstructing material. After the obstructing material is removed, the PLC controller will control the hydraulic cylinder 4 again to drive the valve plate 3 to continue to close until it is in place. During the closing process, the dust scraper 5 will also effectively prevent dust and debris from entering the valve. At the same time, the limit switch 6 will monitor the position of the valve plate 3 in real time and feed the signal back to the PLC controller.

[0039] The electro-hydraulic PLC flat gate valve of this embodiment supports remote control and automated operation. Users can send open or close signals to the PLC controller through the remote control system. The PLC controller will control the hydraulic station to start or stop working according to the received signal, thereby driving the valve plate 3 to open or close. At the same time, the PLC controller can also monitor the valve's operating status in real time (such as the position of the valve plate 3, the pressure of the hydraulic device, etc.) and feed back the relevant information to the remote control system for users to monitor and manage.

[0040] The valve plate 3 is made of chrome-plated manganese steel, which has excellent wear resistance, erosion resistance and leakage prevention performance, and can meet the unloading requirements of different materials. At the same time, in order to further improve the wear resistance and service life of the valve plate 3, the surface of the valve plate 3 can be specially treated (such as spraying wear-resistant coating, etc.). Steel plates are welded to the sides of the valve plate 3 and placed obliquely around the valve plate 3 for material unloading requirements.

[0041] The design of the pulley block 2 has a significant impact on the operating efficiency and stability of the valve. In this embodiment, the pulley block 2 is fixedly installed by connecting the built-in rotating shaft to the welded frame 1, and the friction is reduced by mirror treatment. In order to further improve the operating efficiency and stability of the pulley block 2, the structure of the pulley block 2 can also be optimized (such as increasing the number of pulleys, adjusting the pulley spacing, etc.).

[0042] The hydraulic device is one of the core components of this utility model, and it has an important influence on the driving force and stability of the valve. In this embodiment, the hydraulic device adopts a dual-cylinder synchronous control method to ensure the smooth operation of the valve plate 3 during the opening and closing process. In order to further improve the driving force and stability of the hydraulic device, the structure and parameters of the hydraulic cylinder 4 can also be optimized (such as increasing the diameter of the hydraulic cylinder 4, increasing the pressure of the hydraulic station, etc.).

[0043] The function of the dust scraper 5 is to prevent dust and debris from entering the valve to ensure the normal operation of the valve. In this embodiment, the dust scraper 5 is built into the gap between the welded frame 1 and the valve plate 3 and fits tightly with the valve plate 3. In order to further improve the blocking effect and service life of the dust scraper 5, the material and structure of the dust scraper 5 can be optimized (such as using wear-resistant materials, increasing the thickness of the dust scraper 5, etc.).

[0044] The function of the limit switch 6 is to detect the opening and closing position of the valve plate 3 and feed the signal back to the PLC controller so as to control the valve accordingly. The limit switch 6 of this utility model is made of a high-precision sensor that can accurately detect the position of the valve plate 3. In order to further improve the accuracy and reliability of the limit switch 6, the type and parameters of the sensor can be optimized (such as using a non-contact sensor, improving the sensor accuracy, etc.).

[0045] The PLC controller is one of the core control components of this invention, and it has a significant impact on the remote control and automated operation of valves. The PLC controller of this invention uses advanced programming languages ​​and algorithms for program design, which can achieve precise control and intelligent management of valves. In order to further improve the control effect and intelligence level of the PLC controller, the program can also be optimized (such as adding fault diagnosis functions, improving control accuracy, etc.).

[0046] This new type of electro-hydraulic PLC flat gate valve improves valve service life: the valve plate 3 is made of chrome-plated manganese steel, which has excellent wear resistance, erosion resistance and leakage prevention performance, effectively reducing the frictional resistance and wear of the valve plate 3 during movement, thereby extending the service life of the valve.

[0047] This new electro-hydraulic PLC flat gate valve improves production efficiency: The valve supports remote control and automated operation, enabling rapid response to production demands and increasing efficiency. Furthermore, innovative designs such as a dual-cylinder synchronously controlled hydraulic system and a dust scraper further enhance the valve's operational efficiency and stability.

[0048] This new type of electro-hydraulic PLC flat gate valve reduces maintenance costs: the valve has a simple overall structure, is easy to maintain, and the connections between the components are firm and reliable, reducing the possibility of failure and thus lowering maintenance costs.

[0049] This new electro-hydraulic PLC-controlled flat gate valve enhances its intelligence level: by combining a PLC controller with a hydraulic actuator, remote control and automated operation of the valve are achieved, thus improving its overall intelligence. Simultaneously, the PLC controller supports fault diagnosis and alarm functions, enabling timely detection and handling of potential problems to ensure the valve's normal operation.

[0050] This new type of electro-hydraulic PLC flat gate valve is highly adaptable: the valve is suitable for unloading block materials under different working conditions, and has wide applicability and promotion value.
