Description

Technical Field

[0001] This utility model relates to the field of chemical energy, and in particular to a gas phase ethane conveying device. Background Technology

[0002] A gaseous ethane conveying device is an optimized piece of equipment for cryogenic ethane systems. By adding a crossover line between the compressor outlet and the external pipeline, a portion of the pressurized and cooled gaseous ethane is directly conveyed downstream, while the remainder is processed and returned to the tank. This reduces the need for high-power unit operation, recovers methane, mitigates the risks associated with cryogenic pipelines, and improves both economic efficiency and safety.

[0003] A typical gaseous ethane conveying device includes a conveying pipeline for transporting gaseous ethane; a compressor to pressurize and increase the conveying power; a flow regulation structure for precise flow control; and temperature and pressure monitoring equipment to ensure safe and stable conveying. Some devices are equipped with special processing systems to address issues such as impurities and phase changes.

[0004] Currently, traditional equipment mostly relies on manual valves to regulate the flow rate of gaseous ethane. This results in low regulation accuracy and large flow fluctuations, making it difficult to adapt to high-precision process requirements. Furthermore, the lack of automatic solenoid valve drive and manual backup design in case of power failure makes flow control easily interrupted. Additionally, the absence of piston sealing structures allows gaseous ethane to easily leak from gaps, leading to material waste and safety risks. Most existing traditional equipment does not use buffer components, failing to absorb pressure fluctuations during gaseous ethane transport. High-pressure impacts act directly on pipes and joints, easily causing pipe vibration and component wear. Moreover, the lack of pressure gauges for real-time pressure monitoring makes it difficult to detect pressure anomalies in a timely manner, reducing transport stability and potentially causing equipment failure due to sudden pressure increases, affecting transport safety and continuity. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas phase ethane conveying device, which aims to improve the existing technology. Most traditional equipment lacks automatic drive with solenoid valves and manual backup design in case of power failure. After power failure, flow control is easily interrupted. At the same time, the lack of piston sealing structure makes gas phase ethane prone to leakage from gaps and high pressure impact directly on the pipeline and joints, which can easily lead to pipeline vibration and component wear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A gas phase ethane conveying device includes a pipeline, one end of which is fixedly connected to a flange, a flow regulating assembly is threadedly connected to one side of the flange, and a buffer assembly is provided at the other end of the pipeline. The flow regulating assembly includes a rotating rod, a regulating ball is fixedly connected to the bottom of the rotating rod, a switch valve is fixedly connected to the top outer wall of the rotating rod, and a solenoid valve is provided at the top of the switch valve.

[0007] As a further description of the above technical solution: The buffer assembly includes a buffer plate, a buffer spring is fixedly connected to the top of the buffer plate, a protective shell is provided on the outer wall of the buffer spring, and a fixing plate is fixedly connected to the top of the buffer spring.

[0008] As a further description of the above technical solution: The drive end of the solenoid valve is fixedly connected to the top of the rotating rod.

[0009] As a further description of the above technical solution: The outer wall of the regulating ball is rotatably connected to the inner wall of the pipe, and the regulating ball has a through hole.

[0010] As a further description of the above technical solution: A piston is provided on the top of the adjusting ball, and the piston is fixedly connected to the outer wall of the rotating rod.

[0011] As a further description of the above technical solution: A fixing plate is fixedly connected to the inner wall of the protective shell.

[0012] As a further description of the above technical solution: A pressure gauge is fixedly connected to the top of the fixed plate.

[0013] As a further description of the above technical solution: The buffer assembly is fixedly connected to flanges at both ends, and the pipe is threaded onto one side of the flange.

[0014] This utility model has the following beneficial effects: In this invention, the flow regulating component has the advantages of both automatic and manual control. When energized, the solenoid valve drives the rotating rod, which in turn drives the regulating ball and the through hole to change the flow area, thereby achieving precise control of the gas phase ethane flow. After power failure, the switch valve can be manually operated to avoid control interruption. The piston sealing gap prevents leakage, and the integrated switch valve component improves adaptability and delivery reliability.

[0015] 2. In this utility model, the buffer assembly uses a buffer plate to withstand the pressure impact of gaseous ethane, the buffer spring absorbs the fluctuation energy through elastic deformation, the protective shell constrains the spring deformation direction to prevent failure, the fixing plate integrates the internal structure to ensure stability, and the pressure gauge monitors the pressure in real time. This effectively smooths out pressure fluctuations during transport, avoids impact damage to the pipeline, improves the stability of gaseous ethane transport, and features a compact structure and convenient maintenance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a gaseous ethane conveying device, including a pipeline 1. One end of the pipeline 1 is fixedly connected to a flange 2, and a flow regulating component 3 is threadedly connected to one side of the flange 2. The flow regulating component 3 integrates a rotating rod 5, an regulating ball 6, and other structures. By rotating the regulating ball 6, the flow area is changed to regulate the flow rate of gaseous ethane. The other end of the pipeline 1 is provided with a buffer component 4. The flow regulating component 3 includes a rotating rod 5, the bottom of which is fixedly connected to the regulating ball 6, and the top outer wall of the rotating rod 5 is fixedly connected to a switch valve 7. The top of the switch valve 7 is provided with a solenoid valve 8, the drive end of which is fixedly connected to the top of the rotating rod 5. The outer wall of the regulating ball 6 is rotatably connected to the inner wall of the pipeline 1. The regulating ball 6 has a through hole 15, which is opened on the regulating ball 6. As the regulating ball 6 rotates, the flow overlap area with the pipeline 1 is changed, thereby precisely regulating the flow rate 15 of gaseous ethane. The top of the regulating ball 6 is provided with a piston 13, which is fixedly connected to the outer wall of the rotating rod 5.

[0020] Reference Figure 1 , Figure 4 and Figure 5The buffer assembly 4 includes a buffer plate 9, a buffer spring 10, etc., which absorb pressure fluctuations during the flow of gaseous ethane, mitigate impacts, and stabilize the delivery pressure. The buffer spring 10 is fixedly connected to the top of the buffer plate 9. A protective shell 11 is provided on the outer wall of the buffer spring 10. The buffer spring 10 absorbs pressure fluctuations transmitted by the buffer plate 9 through elastic deformation, buffering the pressure impact of gaseous ethane. A fixing plate 12 is fixedly connected to the top of the buffer spring 10. The protective shell 11 encloses the buffer spring 10, the fixing plate 12, etc., protecting the internal structure from damage and constraining the deformation direction 11 of the buffer spring 10. The fixing plate 12 is fixedly connected to the inner wall of the protective shell 11. The fixing plate 12 is fixed to the top of the buffer spring 10, providing installation support for the pressure gauge 14 and integrating the internal structure 12 of the buffer assembly 4. The pressure gauge 14 is fixedly connected to the top of the fixing plate 12. Flanges 2 are fixedly connected to both ends of the buffer assembly 4, and the pipe 1 is threadedly connected to one side of the flange 2.

[0021] Working Principle: First, when gaseous ethane is transported in pipeline 1, the flow regulating component 3 achieves precise control through a dual-mode system of automatic drive and manual backup. When energized, the solenoid valve 8 receives a control signal, and its drive end rotates the rotating rod 5, causing the regulating ball 6 to rotate synchronously around the inner wall of pipeline 1. The through-hole 15 on the surface of the regulating ball 6 changes its overlapping area with the flow cross-section of pipeline 1 as the rotation angle changes. The flow rate is maximized when the through-hole 15 is completely aligned with the flow channel of pipeline 1, and shuts off when it is completely misaligned. After power failure, the rotating rod 5 can be rotated directly by manually operating the switch valve 7, synchronously adjusting the position of the regulating ball 6 and the through-hole 15 to ensure uninterrupted flow control. During this process, the piston 13 tightly contacts the gap between the rotating rod 5 and pipeline 1, blocking the leakage path of gaseous ethane. The switch valve 7 also serves as an integrated carrier for both automatic and manual operation, providing installation support and an operating interface for various structures.

[0022] Pressure fluctuations during the flow of gaseous ethane are absorbed by the buffer assembly 4: when high-pressure gaseous ethane impacts the buffer plate 9, the buffer plate 9 transmits the pressure to the buffer spring 10. The spring dissipates the impact energy through elastic deformation, gradually releasing the pressure to stabilize the transport state within the pipeline 1. The protective shell 11 constrains the deformation direction of the buffer spring 10, preventing spring deflection and buffer failure. The fixing plate 12 fixes the top position of the buffer spring 10 to ensure stable spring force and provides an installation reference for the pressure gauge 14. The pressure gauge 14 monitors the pressure changes within the buffer assembly 4 in real time, providing feedback on the stability of the gaseous ethane transport. Furthermore, the flange 2 connects the pipeline 1, the flow regulating assembly 3, and the buffer assembly 4, and bolts ensure a sealed connection of each component, constructing a complete and reliable gaseous ethane transport path.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
