Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline valve technology, specifically a safety chemical pipeline valve. Background Technology
[0002] Chemical pipeline valves are devices installed in chemical pipeline systems to control the flow of fluids, including functions such as shut-off, flow regulation, flow direction change, backflow prevention, pressure stabilization, and pressure relief. They come in many types, and can be categorized by application as gate valves, globe valves, ball valves, butterfly valves, check valves, etc. Different types of valves have different structures and working principles. For example, ball valves open and close by rotating a ball, while butterfly valves control flow by rotating a butterfly plate. Chemical pipeline valves must possess characteristics such as corrosion resistance, high temperature resistance, and good sealing performance to adapt to the complex media and operating conditions in chemical production, ensuring the safe, stable, and efficient operation of the pipeline system. They are indispensable key components in chemical production processes.
[0003] While valves in current chemical pipeline systems can reliably achieve both sealing and opening functions, the traditional manual operation mode presents significant safety hazards. When sudden situations such as overpressure, leakage, or abnormal temperature occur in the pipeline, operators must rush to the site to manually turn the valves to switch states. This process is often delayed due to factors such as distance, road conditions, or hazardous environments. For example, in an emergency scenario where the pressure in a chemical reactor suddenly increases, the medium may have already breached the pipeline's sealing layer within the short time it takes for a person to reach the valve, causing leakage or even a deflagration accident. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes a safe chemical pipeline valve that allows for remote control of the valve, enabling rapid opening and closing and reducing adverse consequences from accidents.
[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a safety chemical pipeline valve, comprising:
[0006] The valve body has a ball valve inside, and a rotating wheel is connected to the upper end of the ball valve via a connecting shaft. The rotating wheel is located above the valve body.
[0007] The drive mechanism includes a motor and a crank. A fixed frame is connected to the valve body. The motor is fixedly mounted on the fixed frame. One end of the crank is fixedly mounted to the output end of the motor, and the other end is rotatably connected to the edge of the wheel.
[0008] The auxiliary components include a high-definition industrial camera and a leak gas detector, both of which are fixedly mounted on a bracket and oriented toward the valve body.
[0009] Furthermore, flanges are provided at both ends of the valve body.
[0010] Furthermore, the connection between the connecting shaft and the valve body is made through a sealed bearing.
[0011] Furthermore, the motor is located directly above the center of the rotor.
[0012] Furthermore, light panels are symmetrically arranged on both sides of the fixing frame, and lighting lamps are provided below the light panels.
[0013] Furthermore, the extended end of the lamp panel is inclined downwards, and the lighting lamp is fixedly mounted on the lower wall of the lamp panel at the end away from the fixing frame.
[0014] Compared with existing technologies, the advantages of this invention are as follows: The combination of a motor and crank in the drive mechanism allows for remote command transmission via an electronic control system. The motor outputs driving force, which is vertically transmitted to the impeller via the crank. This rigid transmission structure enables instantaneous opening and closing of the ball valve, significantly reducing the switching time compared to traditional manual operation. In emergency situations such as abnormal pressure or media leakage in chemical pipelines, it can quickly cut off or connect the pipeline, preventing the spread of danger. The high-definition industrial camera and leak gas detector in the auxiliary components can collect valve operating status and environmental data in real time. This data is fed back to the control terminal through a remote monitoring system. Operators can judge whether the valve is in position and whether there is a potential leak based on the images and data, thereby accurately controlling the valve action. This forms a closed-loop remote management mode of "monitoring-control-feedback," which avoids the safety risks of manual on-site operation and can respond quickly in emergencies, effectively reducing the adverse consequences of accidents.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] Combined with appendix Figure 1 Appendix Figure 2A safety chemical pipeline valve includes: a valve body 1, wherein flanges 10 are provided at both ends of the valve body 1, which facilitates quick connection and fixation with chemical pipelines, improves installation efficiency and provides reliable sealing performance, and can effectively prevent leakage at pipeline connections.
[0022] Combined with appendix Figure 1 Appendix Figure 3 The valve body 1 is equipped with a ball valve 2. The upper end of the ball valve 2 is connected to a rotating wheel 4 via a connecting shaft 3. The rotating wheel 4 is located above the valve body 1. The connecting shaft 3 and the valve body 1 are connected by a sealed bearing, which can reduce the frictional resistance when the connecting shaft 3 rotates. At the same time, the sealing characteristics of the sealed bearing are used to prevent the medium inside the valve body 1 from leaking from the connection, thus ensuring the normal operation of the valve.
[0023] Combined with appendix Figure 1 Appendix Figure 3 The drive mechanism includes a motor 5 and a crank 6. A fixed frame 7 is connected to the valve body 1. The motor 5 is fixedly mounted on the fixed frame 7. One end of the crank 6 is fixedly mounted on the output end of the motor 5, and the other end is rotatably connected to the edge of the rotating wheel 4. The motor 5 is located directly above the center of the rotating wheel 4, so that the driving force output by the motor 5 can be transmitted vertically to the rotating wheel 4, resulting in more uniform force distribution, which can improve the transmission efficiency of the drive mechanism and ensure smooth opening and closing of the ball valve 2.
[0024] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The auxiliary components include a high-definition industrial camera 8 and a gas leak detector 9, both of which are fixedly mounted on a mounting frame 7 and facing the valve body 1. The mounting frame 7 has symmetrically arranged light panels 11 on both sides, with lighting lamps 12 positioned below each light panel 11. The symmetrically arranged lighting lamps 12 provide uniform illumination to the valve body 1 area, facilitating clear imaging of the valve status by the high-definition industrial camera 8. The protruding ends of the light panels 11 are inclined downwards, and the lighting lamps 12 are fixed to the lower wall of the end of the light panel 11 away from the mounting frame 7. This allows the light from the lighting lamps 12 to be more concentrated on the valve body 1, reducing light scattering, enhancing the illumination effect, and further improving the clarity of the image.
[0025] The specific implementation of this utility model is as follows: The pipeline valve is connected to an external power source, and the motor is connected to a remote electrical control system. The valve is fixedly connected to the chemical pipeline via flanges 10 at both ends of the valve body 1, ensuring reliable sealing performance. When the valve needs to be opened or closed, the electrical control system sends a command to the motor 5 of the drive mechanism. The motor 5 rotates, driving the crank 6. The other end of the crank 6 is connected to the edge of the wheel 4, thereby driving the wheel 4 to rotate. The wheel 4 drives the ball valve 2 to rotate inside the valve body 1 via the connecting shaft 3, realizing the opening or closing of the valve. During this process, the high-definition industrial camera 8 and the leak gas detector 9 of the auxiliary components work in real time. The high-definition industrial camera 8 captures the internal state of the valve body 1 and the ball valve 2, and the leak gas detector 9 detects whether there is a medium leak. The light panels 11 and the lighting lamps 12 on both sides of the mounting bracket 7 provide sufficient lighting for the shooting. The captured images and detected data are transmitted to the control terminal through the remote monitoring system. The operator can view the valve operation in real time and adjust the control commands as needed to ensure the valve works normally. The entire process realizes remote control, which is efficient and safe.
