Abstract
Description
Technical Field
[0001] This invention relates to the field of distribution skid technology, specifically to a distribution metering valve assembly skid device for carbon dioxide injection. Background Technology
[0002] In fields such as CO2 enhanced oil recovery in oil and gas fields, chemical reaction gas supply, and food preservation controlled atmosphere, the carbon dioxide injection distribution and metering valve assembly skid is a core piece of equipment. Its core function is to achieve multi-channel distribution, precise metering, and stable delivery of CO2.
[0003] Citing the Chinese patent with publication number "CN222714893U", the base plate has a lifting protection mechanism on its top, and a carbon dioxide pressure-driven injection mechanism on its top. When the lifting plate is detached from the lifting device, it overlaps with the mounting top plate frame, thus reducing the space occupied by the device. The resulting vibration force causes the rotating connecting plate to slide inside the sliding block, which is buffered by a spring and a buffer damping rod. Simultaneously, the rotating connecting plate and the rotating plate drive the connecting slider to slide inside the rectangular plate, which is restricted by the buffer spring.
[0004] The existing equipment generates vibrations during operation, and prolonged vibrations can damage the valve assembly, affecting the efficiency of gas injection. Summary of the Invention

The vortex buffer mechanism includes: A connecting rotating column block is rotatably connected to the bottom of a first fixed block, and a torsion buffer structure is fixedly connected inside the connecting rotating column block; A vortex blade rotor, which is fixedly connected to the bottom of a connecting shaft.
[0007] Preferably, the first fixing block is fixedly connected to the bottom of the support base plate, a first cylindrical spring is fixedly connected to the bottom of the first fixing block, a second fixing block is fixedly connected to the bottom of the first cylindrical spring, and the second fixing block is slidably connected to the buffer support block.
[0008] Preferably, the buffer support block has a first threaded groove inside, the vortex blade rotor is threadedly connected to the first threaded groove, and a first connecting pipe is fixedly connected inside the buffer support block, and a second connecting pipe is fixedly connected to the surface of the first connecting pipe.
[0009] Preferably, a first drive motor is fixedly connected inside the second connecting pipe, and a rotation limit block is fixedly connected inside the first drive motor via an output shaft. A third connecting pipe is fixedly connected to the surface of the second connecting pipe, and an elastic bladder is fixedly connected to the top of the third connecting pipe. A pressure sensor is fixedly connected to the surface of the elastic bladder.
[0010] Preferably, the second connecting pipe includes a front straight pipe section and a rear arc-shaped pipe section coaxially connected, and the entire interior of the second connecting pipe is provided with a second threaded groove, the inner diameter of which gradually decreases along the extension axis of the second connecting pipe from the front straight pipe section to the rear arc-shaped pipe section.
[0011] Preferably, the torsional buffer structure includes a triaxial accelerometer, which is fixedly connected inside the connecting rotating block. A sliding turntable is slidably connected inside the connecting rotating block. The connecting shaft is fixedly connected to the bottom of the sliding turntable.

[0013] Preferably, the emergency pressure relief mechanism includes a fourth connecting pipe, which is fixedly connected inside the buffer support block, and a valve body is fixedly connected to the surface of the fourth connecting pipe.
[0014] This invention provides a skid-mounted device for distributing and metering valves for carbon dioxide injection. It offers the following advantages: 1. This carbon dioxide injection distribution metering valve skid device, by setting up a vortex blade rotor, when a triaxial acceleration sensor detects vertical vibration in the device, the connecting rotating column moves inside the buffer support block. At this time, the vortex blade rotor slides along the first threaded groove, and the vortex blade rotor and silicone oil undergo viscous shearing, thereby reducing the impact of vibration on the device. Compared with the traditional rigid buffer relying solely on springs, this method effectively avoids local stress concentration in the buffer structure that could lead to device damage. Furthermore, with the setting of the second connecting pipe, the silicone oil is squeezed and flows along the second threaded groove towards the third connecting pipe. The resistance of the silicone oil further alleviates the damage of vibration to the device, ensuring the working efficiency of the device.
[0015] 2. This carbon dioxide injection distribution metering valve skid device, by setting up an elastic bladder, works in conjunction with the flow of silicone oil inside the second connecting pipe. The elastic bladder continuously provides the reverse thrust of the flowing silicone oil, improving the efficiency of instantaneous impact absorption, thereby further improving the shock absorption effect of the vortex buffer mechanism. It can also smoothly release the rebound force to ensure the vortex blade rotor returns to its original state. In conjunction with the first cylindrical spring, it further reduces the vertical vibration impact force of the device, thereby improving the working efficiency of the device.
[0016] 3. This carbon dioxide injection distribution metering valve skid device, by setting a sliding rod, when the triaxial acceleration sensor detects vibration in the horizontal torsional direction of the device, the sliding ball, under the action of the second cylindrical spring, quickly absorbs the instantaneous torque impact generated by the device. Combined with the vortex blade rotor buffer, it forms a double protection, effectively reducing the impact of vibration on the working efficiency of the device. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0021] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a skid device for a carbon dioxide dispensing and metering valve assembly, including a base 1, a buffer support block 4 fixedly connected to the top of the base 1, a vortex buffer mechanism 5 fixedly connected inside the buffer support block 4, a support base plate 2 fixedly connected to the top of the vortex buffer mechanism 5, a carbon dioxide dispensing and metering valve assembly 3 and a support frame 8 fixedly connected to the top of the support base plate 2, an emergency pressure relief mechanism 7 fixedly connected inside the buffer support block 4, and high viscosity silicone oil injected inside the buffer support block 4; The vortex buffer mechanism 5 includes: A rotating column block 54 is rotatably connected to the bottom of the first fixed block 51, and a torsion buffer structure 6 is fixedly connected inside the rotating column block 54. The vortex blade rotor 55 is fixedly connected to the bottom of the connecting shaft 68.
[0022] The first fixing block 51 is fixedly connected to the bottom of the support base plate 2. The bottom of the first fixing block 51 is fixedly connected to the first cylindrical spring 52. The bottom of the first cylindrical spring 52 is fixedly connected to the second fixing block 53. The second fixing block 53 is slidably connected to the buffer support block 4.
[0023] The buffer support block 4 has a first threaded groove 56 inside, and the vortex blade rotor 55 is threadedly connected to the first threaded groove 56. The buffer support block 4 also has a first connecting pipe 57 fixedly connected inside, and a second connecting pipe 510 fixedly connected to the surface of the first connecting pipe 57.
[0024] The second connecting pipe 510 is fixedly connected to the inside of a first drive motor 58. The first drive motor 58 is fixedly connected to a rotation limit block 59 through an output shaft. The surface of the second connecting pipe 510 is fixedly connected to a third connecting pipe 512. The top of the third connecting pipe 512 is fixedly connected to an elastic bladder 513. The surface of the elastic bladder 513 is fixedly connected to a pressure sensor 514. The elastic bladder 513 is filled with an appropriate amount of nitrogen.
[0025] The second connecting pipe 510 includes a front straight pipe section and a rear arc-shaped pipe section that are coaxially connected. The entire interior of the second connecting pipe 510 is provided with a second threaded groove 511. The inner diameter of the second threaded groove 511 gradually decreases along the extension axis of the second connecting pipe 510 from the front straight pipe section to the rear arc-shaped pipe section.
[0026] The torsion buffer structure 6 includes a triaxial acceleration sensor 61, which is fixedly connected inside the connecting rotating block 54. A sliding turntable 66 is slidably connected inside the connecting rotating block 54. A connecting shaft 68 is fixedly connected to the bottom of the sliding turntable 66. A slide rod 62 is slidably connected inside the connecting rotating block 54.
[0027] In use, firstly, a suitable amount of high-viscosity silicone oil is injected into the buffer support block 4 through the fourth connecting pipe 72. When the triaxial acceleration sensor 61 detects vertical vibration in the device, the support base plate 2 vibrates. The vibration of the support base plate 2 causes the first fixed block 51 at its bottom to vibrate as well. The vibration of the first fixed block 51 causes the connecting rotating column block 54 to move together. The movement of the connecting rotating column block 54, through the connection between the sliding turntable 66 and the connecting shaft 68, causes the vortex blade rotor 55 to move inside the buffer support block 4. At this time, the vortex blade rotor 55 rotates and moves inside the buffer support block 4 under the action of the first threaded groove 56. At the same time, the first drive motor 58 is started, driving the rotating limit block 59 through the output shaft. The rotation of the rotation limit block 59 ensures that the silicone oil can flow into the interior of the second threaded groove 511. Subsequently, under the action of the vortex blade rotor 55, the silicone oil flows into the interior of the second threaded groove 511 through the first connecting pipe 57. As the inner diameter of the second threaded groove 511 gradually decreases, the resistance gradually increases, effectively mitigating the impact of vibration on the device. The elastic bladder 513 continues to expand, and at this time, the elastic bladder 513 continuously generates a counter-force on the silicone oil, thereby further improving the efficiency of instantaneous impact absorption. With the detection of the pressure sensor 514, the elastic bladder 513 is prevented from breaking due to excessive pressure. When the device vibrates in the vertical direction, the first cylindrical spring 52 further plays a buffering role.
[0028] When the triaxial accelerometer 61 detects vertical vibration in the device by setting up a vortex blade rotor 55, the connecting rotating block 54 moves inside the buffer support block 4. At this time, the vortex blade rotor 55 slides along the first threaded groove 56, and the vortex blade rotor 55 undergoes viscous shearing with the silicone oil, thereby reducing the impact of vibration on the device. Compared with the traditional rigid buffering that relies solely on springs, this method effectively avoids damage to the device caused by local stress concentration in the buffer structure. Furthermore, with the setting of the second connecting pipe 510, the silicone oil is squeezed and flows along the second threaded groove 511 towards the third connecting pipe 512. The resistance of the silicone oil further alleviates the damage to the device caused by vibration and ensures the working efficiency of the device.
[0029] By setting up an elastic bladder 513, which works in conjunction with the flow of silicone oil inside the second connecting pipe 510, the elastic bladder 513 continuously provides the reverse thrust of the flowing silicone oil, thereby improving the efficiency of instantaneous impact absorption and further enhancing the shock absorption effect of the vortex buffer mechanism 5. It can also smoothly release the rebound force to ensure the recovery of the vortex blade rotor 55. In conjunction with the first cylindrical spring 52, it further reduces the vertical vibration impact force of the device, thereby improving the working efficiency of the device.
[0030] Example 2: Please refer to Figure 1-9 Based on Embodiment 1, the present invention provides a technical solution: One end of the slide rod 62 is fixedly connected to a third cylindrical spring 65, and the other end of the slide rod 62 is fixedly connected to a sliding ball 64. There are four slide rods 62, and the four slide rods 62 are arranged in a circular array along the central axis of the connecting rotating block 54. A second cylindrical spring 63 is fixedly connected to the surface of the sliding ball 64, and an elastic arc block 67 is fixedly connected to the inside of the connecting rotating block 54.
[0031] The emergency pressure relief mechanism 7 includes a fourth connecting pipe 72, which is fixedly connected inside the buffer support block 4, and a valve body 71 is fixedly connected to the surface of the fourth connecting pipe 72.
[0032] In use, when the triaxial accelerometer 61 detects horizontal vibration in the device, the sliding ball 64 slides inside the buffer support block 4 under the action of the second cylindrical spring 63, effectively relieving the annular torsional force generated by the device vibration. In conjunction with the extension and contraction of the third cylindrical spring 65, the annular torsional force generated by the device vibration is further relieved. At the same time, under the action of the elastic arc block 67, the impact force of the sliding turntable 66 is further relieved, avoiding structural damage. When the pressure sensor 514 detects that the internal pressure is too high, the valve body 71 can be activated to discharge some of the silicone oil.
[0033] By setting the slide bar 62, when the triaxial acceleration sensor 61 detects vibration in the horizontal torsional direction of the device, the sliding ball 64 quickly absorbs the instantaneous torque impact generated by the device under the action of the second cylindrical spring 63. Together with the vortex blade rotor 55 buffer, it forms a double protection, effectively reducing the impact of vibration on the working efficiency of the device.
[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
