Description

Technical Field

[0001] This invention relates to the field of throttle valve technology, specifically a fast-response electric throttle valve. Background Technology

[0002] In the process of oil and gas field development, the electric throttle valve is a key component of the wellhead and manifold. It is mainly used to transport the oil collected downhole through the electric throttle valve on the wellhead and to control the wellhead production through the electric throttle valve.

[0003] Currently available electric throttle valves offer several advantages over traditional manual throttle valves, including faster response and flow control. However, since electric throttle valves require electricity for control, a power outage means the electric components lose direct control, rendering the throttle valve unable to control flow. This can lead to safety hazards if flow becomes uncontrollable during oil and gas extraction, preventing timely valve reset and closure. Therefore, while electric throttle valves offer advantages, their reliance on electricity is a significant drawback. Although existing technologies incorporate both manual and electric control, manual control requires personnel to physically approach the valve, while electric control allows for remote operation. Consequently, by the time personnel reach the valve after a power outage, oil leaks or overflows may have already occurred, resulting in damage and safety issues. Therefore, a fast-response electric throttle valve is proposed to address these problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a fast-response electric throttle valve, which has the following beneficial effects:

[0018] 1. This fast-response electric throttle valve, through its magnetic induction component, utilizes gravity to control the sliding separation of the threaded sleeve during the power outage of the control motor, thereby releasing the thread lock of the valve stem. Subsequently, the oil and gas pressure in the well will push the valve seat to move automatically upward, pressing against the inlet position of the valve body, thus achieving automatic reset and closure. The entire system utilizes the principle of magnetism generated by electricity. Under energized conditions, magnetic attraction controls the upward movement of the sliding plate, thereby hindering and limiting the two half-sleeves, controlling them to re-lock with the valve stem. This achieves automatic closure and reset of the electric throttle valve after power failure, solving the problem of cumbersome active control of the throttle valve after power failure in existing technologies, and improving the safety and stability of the throttle valve in oil and gas extraction.

[0019] 2. This fast-response electric throttle valve, through its pressure over-limit action component, can reverse the sliding plate after the throttle valve exceeds its own pressure limit value, thereby also contacting the limit of the threaded sleeve, achieving double protection reset and closure. This avoids instability of the throttle valve during high-pressure operation, preventing pressure damage to internal components and indirectly improving the fast response of the electric throttle valve.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 A fast-response electric throttle valve includes a valve body 1; a cylinder 2; and a control mechanism 3 for controlling the flow rate of the valve body 1. The control mechanism 3 includes an electric control component, a magnetic sensing component, and a pressure over-limit action component. The electric control component is used to electrically control the flow rate of the valve body 1. The magnetic sensing component is used to control the electric control component to automatically reset and close the flow channel of the valve body 1 when the power is off. The pressure over-limit action component is used to synchronously control the valve body 1 to reset and close for protection when the flow pressure of the valve body 1 exceeds the pressure limit value. The cylinder 2 is mounted on the valve body 1 through a connector. An inlet pipe 4 is provided at the bottom of the valve body 1, and an outlet pipe 5 is provided on the side of the valve body 1.

[0032] In this embodiment, the electronic control component includes a control motor 301, which is mounted on the cylinder 2 via a connector. The output end of the control motor 301 is connected to a connecting shaft 302. A drive worm gear 303 is fixedly connected to the connecting shaft 302. A drive worm wheel 304 meshes with the surface of the drive worm gear 303. A valve stem 307 is disposed inside the drive worm wheel 304. A threaded sleeve 306 is threadedly connected to the surface of the valve stem 307 and is disposed inside the cylinder 2. A valve cover 308 is connected to the bottom of the valve stem 307. A valve seat 309 is connected to the bottom of the valve cover 308 via two connecting rods 310. The rotation of the control motor 301 drives the rotation of the drive worm gear 303, utilizing the meshing of the worm wheel and worm. The transmission will drive the rotation of the ferrule 305, which rotates with the valve stem 307 via a keyway. The rotation of the valve stem 307 will drive the transmission through the threaded connection between its surface and the threaded sleeve 306, thereby driving the valve stem 307 to move up and down. The up and down movement of the valve stem 307 will drive the bottom valve cover 308 to move up and down, which in turn will drive the valve seat 309 to move up and down via the connecting rod 310. The up and down movement of the valve seat 309 will control the size of the flow port of the valve body 1. When the valve seat 309 moves upward, it will be closer to the flow port of the valve body 1, so the gap will become smaller and the fluid inflow will decrease. When it moves downward, the gap will become larger, and vice versa. Therefore, controlling the up and down movement of the valve seat 309 will achieve the overall flow control effect of the throttle valve.

[0033] Furthermore, the valve body 1 has multiple through holes 312 inside, and the valve seat 309 has multiple through holes 311. The multiple through holes 312 and multiple through holes 311 are arranged in a circular array with the center of the valve seat 309 as the center point. The array angles of the multiple through holes 311 and multiple through holes 312 are staggered. A retaining sleeve 305 is fixedly connected to the drive worm gear 304. The retaining sleeve 305 is slidably connected to the valve stem 307 through a keyway. The multiple through holes 311 are provided to reduce the resistance generated by the valve seat 309 itself during the oil and gas flow process, so that the flow is smoother and there will be no blockage. Then the airflow will enter the internal cavity of the valve body 1 from the opening and the position of the through holes 312, and then flow out from the left side. The staggered angle is so that after the valve seat 309 moves up, its upper surface can abut and seal the through holes 312. After opening, another flow channel is created, reducing the resistance of the valve seat 309 itself in the middle of the oil passage.

[0034] Furthermore, the threaded sleeve 306 includes two half-sleeves 3061, and each half-sleeve 3061 has a triangular prism 3062 fixedly connected to its surface. The cylinder body 2 has an internal groove 3063, and the half-sleeves 3061 are slidably connected within the groove 3063. The triangular prism 3062 engages with the magnetic component. This structure of two half-sleeves 3061 enables threaded connection to the valve stem 307 and provides conditions for releasing the threaded connection constraint, facilitating subsequent automatic and rapid response and reset processes after power failure and pressure over-limit.

[0035] In addition, the magnetic sensing component includes a connector 315, which is fixed to the cylinder 2. A core rod 313 is connected inside the connector 315. An induction coil 314 is wound around the surface of the core rod 313. The two ends of the induction coil 314 are connected to the positive and negative electrodes of the control motor 301 by wires. A sliding plate 317 is provided below the core rod 313. The sliding plate 317 is slidably connected inside the cylinder 2. A clearance groove 318 is provided on the side of the sliding plate 317. When the induction coil 314 is energized, it generates a magnetic force on the core rod 313, which magnetically attracts the sliding plate 317 to move upward. In the power-off state, there will be no current in the control motor 301, so the induction coil 314 will not generate a magnetic force on the core rod 313. At this time, the sliding plate 317 will slide down under gravity, aligning the relief groove 318 with the triangular prism 3062. At this time, the two half-sets 3061 will separate because they are not subject to the abutment limit of the sliding plate 317. During the threaded connection process, when there is no external limit, the thread itself will have an outward tension, so the two half-sets 3061 will separate, creating a certain gap. Finally, the two half-sets 3061 will separate from the threaded connection of the valve stem 307. At this time, the valve stem 307 will be in a state of no vertical constraint, and the triangular prism 3062 on the two half-sets 3061 will slide laterally to the position of the relief groove 318. After the valve stem 307 is no longer restricted by the thread, the inlet pipe 4 at the bottom of the valve body 1 will be subjected to the upward output pressure of oil and gas, which will push the valve seat 309 upward, realizing the automatic closure of the reset pipeline.

[0036] In addition, two sliding plates 317 are provided, and the two sliding plates 317 are symmetrically distributed about the center line of the valve stem 307. A magnetic sheet 316 is fixedly connected to the bottom of the core rod 313, and the magnetic sheet 316 magnetically attracts the two sliding plates 317. Because two half-sets 3061 are provided, two sliding plates 317 must be provided. The longer magnetic sheet 316 will generate a magnetic attraction phenomenon on the two sliding plates 317 after being energized, so as to achieve synchronous attraction on both sides.

[0037] It is worth noting that the pressure over-limit action component includes a pressure rod 319, which is slidably connected inside the valve stem 307. A spindle 331 is connected to the top of the pressure rod 319. A pressure spring 320 is sleeved on the surface of the spindle 331. A rising plate 322 is connected to the spindle 331 via a pin 321. An abutment plate 323 is slidably connected to the surface of the valve stem 307. A sliding toothed plate 324 is fixedly connected to the abutment plate 323. A central gear 325 meshes on the sliding toothed plate 324. A side toothed plate 326 meshes on the surface of the central gear 325. The top of the side toothed plate 326 is connected to the bottom of the sliding plate 317. The central gear 325 is rotatably connected inside the cylinder 2. The overpressure protection component is designed to prevent excessive pressure during operation of the throttle valve, which could cause significant internal pressure loss and damage to internal components over time. Therefore, this component automatically shuts off the throttle valve when the pressure exceeds a certain threshold. When oil or gas enters the internal cavity of the valve body 1 (the transverse space of the outlet pipe 5), the pressure exerted on the pressure rod 319 causes it to rise. This rise compresses the pressure spring 320, and as the pressure rod 319 moves upward, it drives the spindle 331. As the spindle 331 moves upward, the upward movement of the mandrel 331 drives the rising plate 322 to move upward via the pin 321. When it moves upward and contacts the abutment plate 323, it indicates that the pressure value has basically reached the critical value. After exceeding a certain pressure, the abutment plate 323 will be lifted upward simultaneously, which in turn drives the sliding toothed plate 324 to move upward. The upward movement of the sliding toothed plate 324 will drive the rotation of the central gear 325. At this time, the side toothed plate 326 on the other side will slide downward in the opposite direction, which will drive the sliding plate 317 to move downward and squeeze downward. At this time, the two half-sets 3061 will still be released from the limit, thereby releasing the constraint on the up and down movement of the valve stem 307. The valve stem 307 is provided with a sliding groove 3063, and the pin 321 is slidably connected to the sliding groove 3063. The sliding groove 3063 provides the up and down sliding space for the pin 321, thereby controlling the up and down movement of the rising plate 322 according to the pressure change.

[0038] It is worth mentioning that a pressure display assembly is also included. The pressure display assembly includes a pressure dial 327, with a pointer 328 connected to the center of the pressure dial 327. The pointer 328 is connected to a pinion 329 via a shaft. A small gear plate 330 meshes with the surface of the pinion 329. The small gear plate 330 is snapped onto the rising plate 322 via a connector. The purpose of the snapping is to ensure that when the rising plate 322 rotates, the small gear plate 330 also rotates. Therefore, it is necessary to ensure that the angle of the small gear plate 330 does not change when the rising plate 322 rotates. Specifically, the snapping structure is such that the snapping plate in the upper and lower positions is snapped onto the position of the rising plate 322. The up and down movement of the rising plate 322 will only drive the up and down movement of the small gear plate 330, and will not cause any movement to the small gear plate 330 when rotating. The pressure display component can display the real-time pressure value inside the throttle valve. When the pressure rod 319 moves upward under oil and gas pressure, it will drive the riser 322 to move upward, which in turn drives the small gear plate 330 to move upward, which in turn drives the small gear 329 to rotate. The rotation of the small gear 329 will drive the pointer 328 to rotate on the pressure gauge 327. Finally, the rotation of the pointer 328 can be used to check the flow pressure value inside the throttle valve at this time, which can also facilitate the subsequent adjustment of the internal flow of the throttle valve. If the pressure is too high, the flow rate can be increased. The specific adjustment method is adjusted according to the situation on site.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0040] The working principle is as follows: Firstly, during oil and gas extraction, when the throttle valve needs to be electrically controlled, the rotation of the control motor 301 is remotely operated. The rotation of the control motor 301 then drives the rotation of the drive worm gear 303. Through the meshing transmission of the worm gear, the ferrule 305 rotates. The ferrule 305 rotates with the valve stem 307 via a keyway. The rotation of the valve stem 307 is transmitted through its threaded surface and threaded sleeve 306, thus driving the valve stem 307 to move up and down. This movement of the valve stem 307 drives the bottom valve cover 308 to move up and down, which in turn drives the valve seat 309 to move up and down via the connecting rod 310. The up and down movement of the valve seat 309 controls the size of the flow port of the valve body 1. When the valve seat 309 moves upward, it approaches the flow port of the valve body 1, thus reducing the gap and decreasing the fluid inflow. Conversely, when it moves downward, the gap increases, and vice versa. Therefore, controlling the up and down movement of the valve seat 309 achieves overall flow control of the throttle valve. The multiple perforations 311 are designed to reduce the resistance generated by the valve seat 309 during oil and gas flow, ensuring smoother flow and preventing blockages. The gas flow then enters the internal cavity of the valve body 1 through the inlet and through-hole 312, and exits from the left side. The entire throttle valve relies on the control motor 301 for flow control, allowing operators to remotely control the motor for rapid flow control and improved response speed. In the event of a power outage, to ensure the safety of the well and pipelines, the throttle valve needs to be reset for protection.The device incorporates a magnetic induction component, utilizing the principle of magnetization upon energization and demagnetization upon de-energization to control the movement of the sliding plate 317. Specifically, when energized—that is, when the motor 301 is kept energized—electricity is transmitted to the induction coil 314 via wires. The core rod 313 then generates magnetism, producing a magnetic force. This magnetic force is transmitted to the magnetic induction plate 316, which in turn attracts the sliding plate 317, thus controlling its upward movement. The upward movement of the sliding plate 317 controls the movement of the sliding plate. The vertical surface of the sliding plate 317 abuts against the triangular prism 3062, thereby causing the two half-pieces 3061 to merge and press together, abutting against the valve stem 307 to form a threaded connection. Therefore, the rotation of the valve stem 307 at this time will achieve the upward or downward movement through the threaded connection, realizing the flow control effect of the throttle valve. If the power is off, there will be no current in the control motor 301, so the induction coil 314 will not generate a magnetic force on the core rod 313. At this time, the sliding plate 317 will slide down under gravity, allowing the... When the slot 318 is aligned with the triangular prism 3062, the two half-sleeves 3061 are not restrained by the sliding plate 317, and will separate. This is because during the threaded connection process, when there is no external restraint, the thread itself will have an outward tension, causing the two half-sleeves 3061 to separate, creating a certain gap. Ultimately, the two half-sleeves 3061 will separate from the threaded connection of the valve stem 307, and the valve stem 307 will be in a state of no vertical constraint. Meanwhile, the triangular prism 3062 on the two half-sleeves 3061 will slide laterally. When the valve stem 307 moves to the position of the clearance groove 318, it is no longer restricted by the thread. The inlet pipe 4 at the bottom of the valve body 1 is subjected to the upward output pressure of oil and gas, which will push the valve seat 309 to move upward. Since the valve seat 309 is located at the center of gravity of the flow channel, it will generate a certain resistance to the flow channel. Therefore, the valve seat 309 will be automatically pressed against the internal flow port of the valve body 1, realizing the overall automatic reset and sealing effect. There is no need for the operator to manually control it, which improves the overall power failure response rate of the throttle valve and improves the safety of the oil pipe when the power is off.Furthermore, this technical solution also includes a pressure over-limit action component. Its main function is to prevent excessive pressure during throttle valve operation, which could cause significant internal pressure loss in the valve body 1 and, over prolonged operation, easily lead to lifespan damage to internal structural components. Therefore, a component is included to automatically close and protect the throttle valve when the pressure exceeds a certain threshold. Specifically, when oil or gas enters the internal cavity of the valve body 1, specifically the lateral connecting space of the outlet pipe 5, the oil or gas pressure acts on the pressure rod 319, causing it to rise. During this rise, the pressure spring 320 is compressed. As the pressure rod 319 moves upward, it drives the spindle 331 upward. The upward movement of the spindle 331, via the pin 321, drives the rising plate 322 upward. When it reaches contact with the abutment plate 323, the pressure value has essentially reached the critical value. Exceeding a certain pressure will then simultaneously lift the abutment plate 323. The upward movement of the sliding toothed plate 324 causes the sliding toothed plate 324 to move upward, which in turn causes the central gear 325 to rotate. At this time, the side toothed plate 326 on the other side will slide downward in the opposite direction, thereby causing the sliding plate 317 to move downward. Therefore, even when energized, the magnetic force is definitely less than the oil and gas pressure action value. So even under magnetic attraction, the sliding plate 317 will still be squeezed and slid down. At this time, the two half-sets 3061 will still release the limit, thereby releasing the constraint on the valve stem 307. Similarly, the oil and gas pressure of the bottom inlet pipe 4 will once again push up the valve seat 309 to achieve the self-sealing effect of the flow port. Therefore, the overall scheme achieves double-layer reset protection, thereby improving the overall operating stability of the throttle valve, the pressure over-limit, and the response rate under power failure. Finally, the protection protects the pipeline and avoids oil and gas leakage and overflow caused by the throttle valve not resetting and closing in time after power failure.
