Description

Technical Field

[0001] This invention relates to the field of throttling manifold technology, specifically a throttling manifold with an adjustable throttling fixed nozzle. Background Technology

[0002] Choke manifolds are essential equipment for controlling well kicks and implementing oil and gas well pressure control technologies. With the blowout preventer (BOP) closed, the choke valve is used to control a certain casing pressure to maintain the bottom hole pressure slightly higher than the formation pressure, preventing further inflow of formation fluids into the well. Furthermore, during well shut-in, the choke manifold can be used to release pressure for a soft shut-in. The choke manifold is an accessory device to the hydraulic BOP and a key component in controlling well kicks and oil and gas well pressure. It performs well control operations through the choke valve's throttling action, replacing contaminated mud in the well, while simultaneously controlling the casing and riser pressures at the wellhead, restoring the mud column's pressure control at the bottom hole, and preventing overflow. The choke valve's pressure release reduces wellhead pressure, achieving a "soft shut-in," while the large-volume release from the blowout valve reduces wellhead casing pressure, protecting the BOP assembly.

[0003] When the throttling manifold is in use, the opening size of the fixed nozzle cannot be adjusted, which can cause excessive oil pressure in the oil field to spray out from the fixed nozzle, resulting in oil splashing and waste. At the same time, during the use of the throttling manifold, valves are usually used to throttle the oil discharge. When the valves are subjected to oil erosion for a long time, the valve seals will wear down and they will no longer be able to effectively throttle the oil discharge. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a throttling manifold with an adjustable throttling fixed nozzle. Oil can enter the interior of a hollow plate. A movable plate, influenced by oil pressure, can be pushed to move. During movement, the movable plate utilizes the elasticity of a spring to deform and pull the spring. This movement of the movable plate drives the connecting rod and top plate to move. When the top plate moves, it compresses the air bladder, causing the gas inside to concentrate at the top and expand. This expansion of the air bladder drives the measuring plate to move. Based on the movement of the measuring plate, the height of the measuring plate's movement can be measured by observing the scale plate. By adjusting the height of the scale plate's movement, the spacing of the adjusting plate can be adjusted by turning the threaded rod. This allows the adjusting plate to control the opening size of the fixed nozzle according to the oil discharge pressure, preventing... To prevent excessive pressure and splashing during oil discharge, some oil enters the oil box and then flows into the throttling box. The throttling box is connected by a rotating disc; the force and weight of the liquid entering the box cause it to rotate. Multiple throttling plates are fixedly connected inside the throttling box, and their varying heights due to their angled surfaces result in different amounts of oil entering the box. This storage of oil within the throttling box reduces the amount of oil discharged and restricts its flow. As the throttling box rotates, it also drives a brush to clean the oil adsorbed inside, preventing long-term oil buildup and blockage.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A throttling manifold with an adjustable throttling fixed nozzle includes a mounting plate, an oil box fixedly connected to the front surface of the mounting plate, an oil connecting pipe fixedly connected to the lower surface of the oil box and communicating with the interior of the oil box, and a fixed nozzle fixedly connected to the upper surface of the oil box and communicating with the interior of the oil box.

[0007] A hollow plate is attached to the top of the fixed nozzle. An adjusting plate is fixedly connected to the upper surface of the hollow plate. An air bladder is provided on the surface of the adjusting plate. A spring is fixedly connected to the inner wall of the hollow plate. A movable plate is fixedly connected to the end of the spring away from the hollow plate. A connecting rod is fixedly connected to the upper surface of the movable plate. A top plate is fixedly connected to the end of the connecting rod away from the movable plate, and the upper surface of the top plate is attached to the lower surface of the air bladder.

[0008] A measuring plate is provided on the upper surface of the airbag, and scale plates are slidably connected to both sides of the measuring plate.

[0009] A support plate is fixedly connected to the lower surface of the scale plate. The support plate is fixedly connected to the adjustment plate. A threaded rod is connected to the internal thread of the support plate, and the threaded rod is connected to the internal thread of the fixed oil nozzle.

[0010] Preferably, a rotating sleeve is fixedly connected inside the oil box, and a movable turntable is fitted on the outer surface of the rotating sleeve. A baffle is fixedly connected to the end of the rotating sleeve away from the oil box, and the baffle is in contact with the front surface of the movable turntable.

[0011] Preferably, a horizontal plate is fixedly connected to the outer surface of the movable turntable, and a throttling box is fixedly connected to both sides of the horizontal plate, with a throttling plate fixedly connected inside the throttling box.

[0012] Preferably, a fixing plate is fixedly connected to the upper surface of the throttling box, and a brush is provided on the upper surface of the fixing plate.

[0013] Preferably, the end of the oil connecting pipe away from the oil box is connected to a valve body, and an oil inlet pipe is fixedly connected to the side surface of the oil box.

[0014] Preferably, a threaded sleeve is fixedly connected to the front surface of the valve body's handle, and a fastening bolt is connected to the internal thread of the threaded sleeve, and the fastening bolt is connected to the internal thread of the valve body.

[0015] Preferably, the threaded sleeve has a sliding plate inside, and a metal plate is fixedly connected to the side surface of the sliding plate. A magnet is provided on the side surface of the metal plate, and the magnet attracts the side surface of the threaded sleeve.

[0016] Preferably, a pressing plate is fixedly connected to the side surface of the slide plate, and a rubber pad is provided on the side surface of the pressing plate, and the rubber pad is in contact with the outer surface of the fastening bolt.

[0017] Compared with the prior art, the present invention provides a throttling manifold with an adjustable throttling fixed nozzle, which has the following advantages:

[0018] 1. In this invention, oil can enter the interior of the hollow plate. The moving plate is pushed by the oil pressure. When the moving plate moves, it can use the elasticity of the spring to deform and pull the spring. The movement of the moving plate can drive the connecting rod and the top plate to move. When the top plate moves, it can squeeze the airbag, so that the gas in the airbag can concentrate at the top and expand. The expansion of the airbag can drive the measuring plate to move. According to the movement of the measuring plate, the movement height of the measuring plate can be measured by observing the scale plate. By turning the threaded rod according to the movement height of the scale plate, the spacing of the adjusting plate can be adjusted. The adjusting plate can adjust the opening size of the fixed oil nozzle according to the pressure when the oil is discharged, so as to prevent the oil from splashing due to excessive pressure when it is discharged.

[0019] 2. In this invention, when oil enters the oil box, some of the oil can enter the throttling box. Since the throttling box is connected by a movable turntable, when some oil enters the throttling box, the throttling box is rotated by the force and weight of the liquid entering. Since multiple throttling plates are fixedly connected inside the throttling box, the installation height of the multiple throttling plates is different due to the inclined surface of the throttling plate surface. Therefore, the amount of oil entering the throttling box is also different. By storing some oil in the throttling box, the amount of oil discharged can be reduced and the discharge of oil can be blocked to throttle the discharge of oil. When the throttling box rotates, the throttling box can drive the brush to rotate. The brush can clean the oil adsorbed inside the oil box and prevent the oil from accumulating in the oil box for a long time and causing blockage.

[0020] 3. Based on the rotation of the valve body handle, the present invention can turn the fastening bolt, allowing it to enter the valve body through a designated threaded hole to pre-fix the valve body handle. The sliding of the sliding plate and the threaded sleeve pushes the metal plate to one side, allowing the metal plate to push the sliding plate and the extrusion plate together. The movement of the extrusion plate allows the rubber pad to adhere to the surface of the fastening bolt. The movement of the metal plate causes the magnet to attract the threaded sleeve at the valve body handle, fixing the metal plate in place. Thus, when the valve body is opened or closed, the fastening bolt can fix the rotation of the valve body handle, preventing the valve body from slipping due to pressure. Attached Figure Description

When the oil field is being exploited, the oil in the oil field can enter the oil connecting pipe 2 and the oil box 3 and be discharged through the fixed oil nozzle 4. After entering the interior of the fixed nozzle 4, the oil can enter the interior of the hollow plate 19. The moving plate 20 can be pushed to move under the influence of the oil pressure. When the moving plate 20 moves, the elasticity of the spring 22 can be used to deform the spring 22 and pull it. The movement of the moving plate 20 can drive the connecting rod 23 and the top plate 24 to move. When the top plate 24 moves, it can squeeze the air bag 18, so that the gas in the air bag 18 can be concentrated at the top and expand. The expansion of the air bag 18 can drive the measuring plate 17 to move. According to the movement of the measuring plate 17, the scale plate 16 can be observed to measure the movement height of the measuring plate 17.

Since the throttling box 12 is connected by the rotating movable turntable 7, when some oil... When the liquid enters the throttling box 12, the throttling box 12 is rotated by the force and weight of the liquid entering, using the movable turntable 7. Since multiple throttling plates 9 are fixedly connected inside the throttling box 12, the installation height of the multiple throttling plates 9 is different due to the inclined surface of the throttling plate 9. Therefore, the amount of oil entering the throttling box 12 is also different.

When the throttling box 12 is rotating, the throttling box 12 can drive the brush 10 to rotate.

The oil is then discharged through the fixed nozzle 4. Some oil enters the throttling box 12. Due to the inclined surface of the throttling plates 9, the installation height of multiple throttling plates 9 varies, resulting in different amounts of oil entering the throttling box 12. By storing some oil in the throttling box 12, the amount of oil discharged is reduced, and the discharge is blocked, thus throttling the oil flow. When the throttling box 12 rotates, it drives the brush 10 to rotate, cleaning the oil adsorbed inside the oil box 3. After the oil enters the fixed nozzle 4, it enters the hollow plate 19.

The movement of moving plate 20 can drive connecting rod 23 and top plate 24 to move. When top plate 24 moves, it can squeeze airbag 18, so that the gas in airbag 18 can concentrate at the top and expand. The expansion of airbag 18 can drive measuring plate 17 to move. According to the movement of measuring plate 17, the movement height of measuring plate 17 can be measured by scale plate 16.
