Description

Technical Field

[0001] This utility model belongs to the field of drilling rig pipeline technology, and more specifically, it relates to an adjustable throttling manifold. Background Technology

[0002] During drilling, drilling mud is injected downhole from the wellhead. To control the mud flow and pressure, choke manifolds are typically used for regulation. By adjusting the opening and number of choke manifolds, precise control of mud flow and pressure can be achieved, ensuring the safety and stability of drilling operations. An existing adjustable choke manifold (publication number CN206429228U) uses an adjustable choke fixed nozzle to determine a specific choke orifice diameter, controlling two choke paths and one direct discharge path. This allows for precise control of tubing and casing pressure during the post-fracturing blowout and drainage process. However, because the adjustable choke fixed nozzle uses a threaded rod to control the choke orifice diameter, the markings are not obvious, making it difficult to quickly identify during routine inspections, thus reducing inspection efficiency. Furthermore, the adjustment speed is slow. Therefore, an adjustable choke manifold is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable throttling manifold. The scale on the indicator dial allows inspectors to more easily locate the throttling orifice diameter parameters. Furthermore, the throttling orifice diameter can be adjusted by rotating the movable rod, which is more convenient and faster than rotating a threaded rod. This solves the problems mentioned in the background art, where the adjustable throttling fixed nozzle uses a threaded rod to control the throttling orifice diameter, resulting in unclear markings and difficulty in quick identification during daily inspections, thus reducing inspection efficiency and causing slow adjustment speeds.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable throttling manifold, including a manifold body and an oil nozzle, the oil nozzle including an outer shell, an inlet and an outlet on the outer side of the outer shell, a variable diameter groove on the inner side of the outer shell, a variable diameter block on the inner side of the variable diameter groove, a connecting rod fixed on one side of the variable diameter block, and an adjustment component on one end of the oil nozzle;

[0005] The adjustment assembly includes an indicator dial fixed to one end of the outer casing. A gear is rotatably connected to the top surface of the indicator dial, and a rack is meshed with the outer side of the gear. One end of the rack is fixedly connected to one end of a connecting rod. A rotating rod is fixed to the upper end of the gear's shaft. A toothed groove is formed on the bottom surface of the indicator dial, and a movable groove and scale are formed on the top surface of the indicator dial. A movable block is slidably connected to the inner side of the movable groove. The movable block has an arc-shaped structure. An arc-shaped rack is fixed to the bottom surface of the movable block, and the top surface of the arc-shaped rack meshes with the inner side of the toothed groove. A sleeve is fixed to the top surface of the rotating rod, and a movable rod is slidably connected to the inner side of the sleeve. The lower end of the movable rod passes through the interior of the sleeve and the rotating rod and is fixedly connected to the top surface of the movable block. A spring is fixed between the movable rod and the sleeve.

[0006] As a preferred embodiment of this utility model, the inner side of the variable diameter groove is connected to the interior of the input port and the output port, respectively.

[0007] As a preferred embodiment of this utility model, one end of the connecting rod extends through the interior of the outer casing to the exterior.

[0008] As a preferred embodiment of this invention, the lower end of the gear shaft coincides with the center of the indicator disc.

[0009] As a preferred embodiment of this utility model, the movable groove has an arc-shaped structure, and the center of the movable groove coincides with the center of the indicator disc.

[0010] As a preferred embodiment of this utility model, the tooth grooves are arranged in an arc-shaped structure.

[0011] As a preferred embodiment of this invention, one end of the rotating rod corresponds to the scale.

[0012] This utility model provides an adjustable throttling manifold, which has the following beneficial effects:

[0023] Please see Figures 1 to 4This utility model provides a technical solution: an adjustable throttling manifold, including a manifold body 1 and an oil nozzle 2. The oil nozzle 2 includes a housing 26, with an inlet 21 and an outlet 22 on the outer side of the housing 26, a variable diameter groove 23 on the inner side of the housing 26, a variable diameter block 24 on the inner side of the variable diameter groove 23, and a connecting rod 25 fixed to one side of the variable diameter block 24. One end of the oil nozzle 2 is provided with an adjustment component 3, which includes an indicator disk 31 fixed to one end of the housing 26. A gear 32 is rotatably connected to the top surface of the indicator disk 31, and a rack 33 is meshed with the outer side of the gear 32. One end of the rack 33 is fixedly connected to one end of the connecting rod 25. A rotating rod 34 is fixed to the upper end of the shaft of the gear 32. A toothed groove 35 is provided on the bottom surface of the indicator disk 31, and a movable groove 36 and a scale 37 are provided on the top surface of the indicator disk 31. A movable block 38 is slidably connected to the inner side of the movable groove 36. The movable block 38 has an arc-shaped structure. An arc-shaped rack 39 is fixed on the bottom surface of the movable block 38. The top surface of the arc-shaped rack 39 meshes with the inner side of the tooth groove 35. A sleeve 310 is fixed on the top surface of the rotating rod 34. A movable rod 311 is slidably connected to the inner side of the sleeve 310. The lower end of the movable rod 311 passes through the interior of the sleeve 310 and the rotating rod 34 and is fixedly connected to the top surface of the movable block 38. A spring 312 is fixed between the movable rod 311 and the sleeve 310. The inner side of the variable diameter groove 23 is connected to the interior of the input port 21 and the output port 22 respectively. One end of the connecting rod 25 passes through the interior of the outer shell 26 and extends to the outside. The lower end of the shaft of the gear 32 coincides with the center of the indicator disk 31. The movable groove 36 has an arc-shaped structure. The center of the movable groove 36 coincides with the center of the indicator disk 31. The tooth groove 35 is arranged in an arc-shaped structure. One end of the rotating rod 34 corresponds to the scale 37.

[0024] When the oil nozzle 2 needs adjustment, the utility model involves holding the sleeve 310 and pressing the movable rod 311. The movable rod 311 pushes the movable block 38 downward along the movable groove 36. The movable block 38 drives the arc-shaped rack 39 away from the toothed groove 35 on the indicator plate 31, allowing the rotating rod 34 to rotate freely. During the rotation of the rotating rod 34, the rotating rod 34 drives the gear 32 to rotate. The gear 32 drives the connecting rod 25 to move through the rack 33. The connecting rod 25 drives the variable diameter block 24 to move along the inner side of the variable diameter groove 23, thereby changing the throttling orifice diameter. At the same time, the rotating rod... One end of 34 corresponds to scale 37, indicating the size of the throttling orifice. After adjustment, release the pressed movable rod 311. Under the action of spring 312, the movable rod 311 moves upward and drives the arc-shaped rack 39 to engage with the toothed groove 35 on the indicator plate 31 through the movable block 38, thereby limiting the position of the rotating rod 34. Through the above process, the scale 37 on the indicator plate 31 allows the inspector to find the throttling orifice parameter more conveniently. At the same time, the throttling orifice can be adjusted by rotating the movable rod 311, which is more convenient and faster than rotating the threaded rod.

[0025] The specific usage and function of this embodiment are as follows: When the oil nozzle 2 needs to be adjusted, the sleeve 310 is held and the movable rod 311 is pressed. The movable rod 311 pushes the movable block 38 to move downward along the movable groove 36. The movable block 38 drives the arc-shaped rack 39 away from the tooth groove 35 on the indicator plate 31, so that the rotating rod 34 can rotate freely. During the rotation of the rotating rod 34, the rotating rod 34 drives the gear 32 to rotate. The gear 32 drives the connecting rod 25 to move through the rack 33. The connecting rod 25 drives the variable diameter block 24 to move along the inner side of the variable diameter groove 23, thereby changing the throttling orifice diameter. At the same time, one end of the rotating rod 34 corresponds to the scale 37, indicating the size of the throttling orifice diameter. After the adjustment is completed, the pressed movable rod 311 is released. Under the action of the spring 312, the movable rod 311 moves upward and drives the arc-shaped rack 39 to engage with the tooth groove 35 on the indicator plate 31 through the movable block 38, thereby restricting the position of the rotating rod 34.
