Description

Technical Field

[0001] This utility model relates to the field of oil and gas storage and transportation technology, and in particular to an oil and gas storage and transportation pressure relief valve that is easy to adjust the connection position. Background Technology

[0002] As a safety device in oil and gas storage and transportation equipment, the pressure relief valve works based on the principle of spring force and medium pressure balance. In crude oil extraction, gathering and transportation, long-distance pipelines, storage and refining, it automatically relieves pressure in the process of overpressure to ensure the safety of the equipment, protect the equipment and pipelines, and maintain stable operation. In oil and gas storage and transportation equipment, the pressure relief valve is easy to adjust the connection position. This is due to many considerations, such as convenient installation and maintenance (adapting to different equipment layouts, reducing installation difficulty and cost, and facilitating maintenance and repair), optimized equipment performance (optimized pressure control, reduced pressure loss), and adaptability to changes in operating conditions (coping with flow fluctuations and adapting to process adjustments).

[0003] Oil and gas storage and transportation pressure relief valves that are easy to adjust the connection position generally consist of a valve body, a pressure control part, and a connection part. Under normal pressure, the spring force presses the valve core onto the valve seat and the valve is closed. When the pressure exceeds the set value, the medium pressure overcomes the spring force and pushes the valve core to open and relieve pressure. After the pressure drops, the spring force closes the valve. Pressure relief valves with electronic components also achieve more precise pressure control and rapid response through pressure sensors and control devices.

[0004] Existing pressure relief valves for oil and gas storage and transportation, which are designed for easy adjustment of connection positions, cannot be quickly disassembled or installed. During regular maintenance, repairs, or component replacement, the time-consuming and labor-intensive disassembly and installation processes require more manpower, prolonging maintenance time and increasing downtime, thus affecting the normal production schedule of oil and gas storage and transportation and causing indirect economic losses. In emergency situations involving oil and gas storage and transportation units, such as pressure relief valve malfunctions preventing normal pressure relief or requiring emergency replacement of the valve to cope with special operating conditions, the inability to quickly disassemble and install will delay maintenance or replacement work, extending the time the unit faces risks such as overpressure and increasing the severity of accidents. Therefore, a pressure relief valve for oil and gas storage and transportation with an easily adjustable connection position is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an oil and gas storage and transportation pressure relief valve that is easy to adjust the connection position, aiming to improve the problem that the existing technology cannot achieve quick disassembly or installation of oil and gas storage and transportation pressure relief valves.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An oil and gas storage and transportation pressure relief valve with easy-to-adjust connection position includes a pressure relief valve, two outer shells are slidably connected to the outer side of the pressure relief valve, a limiting component for restricting parts is slidably connected inside the two outer shells, a fixing ring is fixedly connected to both sides of the pressure relief valve, a driving component for driving parts is fixedly connected to the outer side of the fixing ring, a rotating ring is rotatably connected inside the driving component, a plurality of driving blocks are rotatably connected inside the rotating ring, a limiting plate is slidably connected inside the driving block, and a clamping plate is fixedly connected to one end of the limiting plate; As a further description of the above technical solution: The limiting component includes a sliding shell, a sliding rod slidably connected inside the sliding shell, multiple rotating plates rotatably connected inside the sliding rod, and a spring fixedly connected inside the sliding rod. As a further description of the above technical solution: The driving component includes a cylinder, which is rotatably connected to the outside of the fixed ring. The driving end of the cylinder is rotatably connected to a linkage plate, and the inside of the rotating ring is fixedly connected to the outside of the linkage plate. As a further description of the above technical solution: The other end of the second spring is fixedly connected to the inside of the sliding shell, and a limiting ring is fixedly connected to the outside of the sliding shell; As a further description of the above technical solution: A spring is fixedly connected inside the rotating plate, and the other end of the spring is fixedly connected inside the sliding shell.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the cylinder drives the linkage plate, the linkage plate drives the rotating ring, the rotating ring drives the driving block, the driving block drives the cylinder, and the cylinder drives the clamping plate, thereby realizing the rapid installation or disassembly of the pressure relief valve. The cylinder drive can provide more precise power control. Compared with manual operation, the clamping plate can be moved to the predetermined position more accurately when installing the pressure relief valve, making the connection position between the pressure relief valve and the pipeline more precise. This ensures the installation accuracy requirements such as coaxiality between the pipeline and the pressure relief valve, and helps to reduce problems such as leakage caused by installation deviation.

In this utility model, the pressure relief valve is protected by a shell in conjunction with a sliding shell, a sliding shell in conjunction with a sliding rod, a sliding rod in conjunction with a spring, and a spring in conjunction with a rotating plate. This structural design allows the shell to be quickly fixed when installed on the pressure relief valve by simply passing the sliding shell through the shell and using the cooperation of the rotating plate and the spring, without the need for complicated tools and tedious operating steps, which greatly improves the installation efficiency.

[0011] 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.

[0012] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of an oil and gas storage and transportation pressure relief valve that is easy to adjust the connection position. The valve includes a pressure relief valve 1, which is the core component of the entire device. It can accurately sense pressure changes within the pipeline and promptly open to relieve pressure when the pressure exceeds a set value, ensuring the safe and stable operation of the oil and gas storage and transportation device. Two outer shells 2 are slidably connected to the outside of the pressure relief valve 1. These shells 2 are tightly fitted to the outside of the pressure relief valve 1, protecting it from damage such as impacts and corrosion from the external environment, ensuring that the pressure relief valve 1 is always in good working condition. The two outer shells 2 are internally slidably connected to limiting components. These limiting components effectively constrain the position and range of motion of relevant components, preventing device malfunctions due to loosening or displacement of components, and ensuring the reliability of the entire device.

[0013] Both sides of the pressure relief valve 1 are fixedly connected with fixing rings 9. The fixing rings 9 provide a stable support point for the subsequent installation of the drive component, so that the drive component can be firmly connected to the pressure relief valve 1, ensuring stable and reliable force transmission during operation. The outer side of the fixing rings 9 is fixedly connected with a drive component for driving the parts. Through ingenious mechanical structure design, the drive component can accurately transmit power to other parts, realizing precise control of the connection and position adjustment of the pressure relief valve 1 with the pipeline.

[0014] The drive component has a rotating ring 10 internally connected to it. The rotating ring 10 can rotate flexibly under the drive component. Through its own rotation, it drives the internally connected drive block 12, thereby realizing a series of mechanical actions. The rotating ring 10 has multiple drive blocks 12 internally connected to it. Driven by the rotating ring 10, the drive block 12 can convert the circular motion into linear motion, thereby pushing the limiting plate 13 to produce displacement and completing the drive of related components. The limiting plate 13 is slidably connected inside the drive block 12. The limiting plate 13 can slide smoothly within the drive block 12. Under the push of the drive block 12, the limiting plate 13 can rotate around one end within the fixed ring 9, thereby driving the clamping plate 14.

[0015] One end of the limiting plate 13 is rotatably connected to the inside of the fixed ring 9. This rotatable connection allows the limiting plate 13 to rotate around the fixed ring 9 as a fulcrum, providing a stable motion basis for the subsequent driving of the clamping plate 14. One end of the limiting plate 13 is fixedly connected to the clamping plate 14. Under the drive of the limiting plate 13, the clamping plate 14 can move towards the pipeline to achieve tight clamping of the pipeline, ensuring that the pressure relief valve 1 is firmly connected to the pipeline. The outer side of the clamping plate 14 is slidably connected to the inside of the rotating ring 10. With the assistance of the rotating ring 10, the movement of the clamping plate 14 is more stable, ensuring the stability and reliability of the pipeline clamping. The driving component includes a cylinder 11. As the power source of the driving component, the cylinder 11 can provide a strong and stable driving force. Through its own telescopic movement, it drives the linkage plate 15 to achieve the corresponding displacement.

[0016] Cylinder 11 is rotatably connected to the outside of fixed ring 9. This rotatable connection allows cylinder 11 to flexibly adjust its angle according to actual needs during operation, ensuring effective power transmission. A linkage plate 15 is rotatably connected to the drive end of cylinder 11. The linkage plate 15 effectively transmits the linear motion of cylinder 11 to rotating ring 10, causing rotating ring 10 to move and rotate. The inside of rotating ring 10 is fixedly connected to the outside of linkage plate 15, ensuring coordinated movement between the two. This precisely transmits the power of cylinder 11 to various related parts, enabling the installation and position adjustment of pressure relief valve 1. Reference Figures 1 to 3 The limiting component includes a sliding shell 3, which slides smoothly within the outer shell 2, enabling quick installation and disassembly. This facilitates maintenance and adjustment of the device by staff. One side of the sliding shell 3 is slidably connected to the outside of the outer shell 2. Its sliding connection design makes the installation and disassembly process simple and convenient, greatly improving work efficiency. The sliding shell 3 has a sliding groove 16 inside, which provides a precise movement track for the rotating plate 6 and the sliding rod 4, ensuring that the movement of the parts within the sliding shell 3 is stable and accurate.

[0017] The sliding shell 3 has a sliding rod 4 slidably connected inside. Under the constraint of the sliding groove 16, the sliding rod 4 can slide along a predetermined direction to effectively control the rotating plate 6. Multiple rotating plates 6 are rotatably connected inside the sliding rod 4. The rotating plates 6 can rotate flexibly under the drive of the sliding rod 4. When the sliding shell 3 passes through the outer shell 2, the rotating plates 6 can be squeezed back into the sliding shell 3, and can pop out again at a suitable position to effectively restrict the two outer shells 2. The outer side of the rotating plate 6 is slidably connected to the inside of the outer shell 2. During installation and disassembly, the sliding cooperation between the rotating plate 6 and the outer shell 2 can achieve tight locking and quick unlocking of the two outer shells 2, making the operation convenient and quick.

[0018] The outer side of the rotating plate 6 is slidably connected to the inside of the slide groove 16, ensuring that the rotating plate 6 remains stable during rotation and sliding without any deviation or jamming. A spring 5 is fixedly connected inside the rotating plate 6. The spring 5 stores elastic potential energy when the rotating plate 6 is compressed. When the external force disappears, it can quickly release the energy to push the rotating plate 6 out, thereby achieving the locking function of the two outer shells 2. The other end of the spring 5 is fixedly connected to the inside of the sliding shell 3 to ensure the stability of the fixed position of the spring 5, thereby ensuring that its force on the rotating plate 6 is accurate and effective.

[0019] A second spring 7 is fixedly connected inside the sliding rod 4. When the sliding rod 4 is pressed, the second spring 7 generates a reaction force, which provides power for the sliding rod 4 to reset, ensuring that the operation of the limiting component has good feel and reliability. The other end of the second spring 7 is fixedly connected inside the sliding shell 3 to ensure the stable installation of the second spring 7 and enable it to function normally. A limiting ring 8 is fixedly connected to the outside of the sliding shell 3. The limiting ring 8 can prevent the sliding shell 3 from sliding out of the outer shell 2, and plays a limiting role to ensure the normal operation of the entire limiting component.

[0020] 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.
