Description

Technical Field

[0001] The invention relates to the technical field of throttle valves, and in particular to a novel intelligent throttle valve device. Background Art

[0002] The throttle valve is the core component of the throttle manifold used in the well control device of the oil and gas industry. Its main function is to maintain a certain casing pressure by opening and closing it when implementing the oil and gas well pressure control technology, and stabilize the bottom hole pressure change within a certain narrow range. The principle of the throttle valve is to use the size of the fluid through hole to achieve the purpose of throttling.

[0003] Valve travel linearity is critical to the stable operation of fluid control systems. Travel linearity means that there is a direct and proportional relationship between valve travel and the flow rate through the valve. This characteristic simplifies flow control logic, making it easier for operators or automatic control systems to predict and regulate fluid flow.

[0004] Existing throttle valves usually use a threaded valve stem to control the size of the opening. The main advantage of this design is that it provides extremely high precision and adjustment capability. By accurately controlling the rotation of the valve stem, the valve opening can be fine-tuned, thereby accurately controlling the flow rate of the fluid. However, in order to improve the linear accuracy of the valve opening, that is, to ensure that each tiny displacement of the valve stem can accurately reflect the change in flow, the valve stem needs to move more finely and slowly during the adjustment process, which will cause the valve to be fully opened or fully closed. The speed is reduced, and in the pipeline system, when an emergency such as a blockage or leakage occurs, the valve needs to be quickly fully opened or fully closed to cut off the fluid flow or restore the flow. However, since the throttle valve sacrifices the speed of full opening and full closing when pursuing high-precision linear control, this will prolong the time required to deal with the emergency, and measures cannot be taken in time, resulting in the expansion of the accident or damage to the equipment. Based on this, the present invention purposely provides a new intelligent throttle valve device that improves the linearity of the valve opening while ensuring the full opening and closing rate of the valve. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a new intelligent throttle valve device that improves the linearity of the valve opening while ensuring the full opening and closing rate of the valve, so as to solve the technical problem that the throttle valve cannot be quickly fully opened or closed in emergency situations such as blockage or leakage in the pipeline.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A novel intelligent throttle valve device, comprising:

[0008] A valve body, in which a valve seat is fixedly installed, and a valve cover is fixedly installed on the top, a valve stem is slidably installed in the valve cover, and a bracket is fixedly installed on the top, a clamping block is fixedly installed on the valve stem, and a valve core is fixedly installed on the bottom end, and the vertical position of the valve core relative to the valve seat is the opening, a fixed cylinder is fixedly installed on the top of the bracket, a driving assembly and a transmission assembly are arranged in the fixed cylinder, and the transmission assembly drives the valve stem to reciprocate, a support plate is fixedly installed in the fixed cylinder, and a first gear ring is rotatably installed at the bottom of the support plate, and the first gear ring is driven to reciprocate by the driving assembly;

[0009] A control component, which is arranged on the valve body and connected to the drive component and the transmission component, is used to determine whether the valve body opening size is appropriate and whether the opening size needs to be urgently adjusted and make corresponding adjustments, and the control component is connected to the intelligent electric actuator; and

[0010] The sleeve is slidably mounted on the support plate, and a threaded groove is provided on its surface. The threaded groove is threadedly connected to the inner ring of the first gear ring. A telescopic part is fixedly mounted on the sleeve. The telescopic part is used to drive the valve stem to rise and fall, and is connected to the intelligent electric actuator. A card slot and a slide groove are provided in the sleeve. When the transmission assembly drives the valve stem to reciprocate, when the card block is rotated into the card slot, the valve stem is engaged with the sleeve, and the valve stem and the sleeve are lifted and lowered synchronously to adjust the opening size normally; when the card block is rotated into the slide groove, the valve stem and the sleeve are slidably connected. At this time, the valve stem is lifted and lowered alone to adjust the opening size urgently.

[0011] As a further solution of the present invention: the distance between the clamping groove and the top plate of the sleeve is consistent with the distance between the clamping groove and the bottom plate of the sleeve, and both are not less than the maximum distance between the valve core and the valve seat.

[0012] As a further solution of the present invention: a plurality of steel balls are rotatably installed in the sleeve, the plurality of steel balls have different heights and are arranged circumferentially, and the valve stem and the steel balls are rollingly matched.

[0013] As a further solution of the present invention: the driving assembly includes a first gear, a servo motor, a U-shaped block and a limit block. The first gear is rotatably installed at the bottom of the support plate, meshing with the first gear ring, and is driven to reciprocate by a servo motor installed on the top of the support plate. The servo motor is connected to the intelligent electric actuator. The two U-shaped blocks are respectively arranged on both sides of the sleeve, and both of them are fixedly connected to the bottom plate of the fixed cylinder. The two limit blocks are respectively fixedly installed at the bottom end of the sleeve, and both are slidingly connected to the two U-shaped block grooves.

[0014] As a further solution of the present invention: the transmission assembly includes a round rod, a U-shaped frame, a second gear ring and a second gear, the round rod is fixedly mounted on the top of the valve stem, the second gear ring and the second gear are both rotatably mounted on the top of the support plate, and the second gear ring is meshed with the second gear, an output source for driving the second gear to reciprocate is installed in the fixed cylinder, the output source is connected to the intelligent electric actuator, the U-shaped frame is fixedly mounted on the second gear ring, and one end of the round rod is located in the U-shaped frame.

[0015] As a further solution of the present invention: when the clamping block is located in the clamping groove, the distance between the round rod and the top of the sleeve is consistent with the distance between the round rod and the top plate of the fixed cylinder, and both are not less than the maximum distance between the valve core and the valve seat.

[0016] As a further solution of the present invention: an arc-shaped groove is provided on the top of the valve stem, an I-shaped block is fixedly mounted on the movable end of the telescopic member, and the I-shaped block is slidably matched with the arc-shaped groove.

[0017] As a further solution of the present invention: an annular O-ring and a gasket are fixedly mounted on the valve seat, and the O-ring is located above the gasket, and both are in contact with the inner wall of the valve body.

[0018] Beneficial effects of the present invention:

[0019] 1. In the present invention, when the block on the valve stem is inserted into the slot on the inner wall of the sleeve, the sleeve can be lifted and lowered slightly each time through the precise cooperation between the thread groove and the first gear ring, so that the opening size of the valve body can be finely adjusted. In combination with the data obtained by the control component, the valve body can be at an appropriate opening size, and the accuracy of the adjustment is improved. The block on the control valve stem is moved out of the slot on the inner wall of the sleeve. At this time, the block slides in the slide groove, and the valve stem and the valve core can be driven to rise or fall quickly through the telescopic member, so that the valve body can be fully opened or fully closed in a short time, and the emergency situation of the valve body can be responded to in time, so as to avoid the situation where the time for handling risks is increased due to the failure to fully open or close quickly, resulting in additional risks.

[0020] 2. In the present invention, by adding a steel ball to the inner wall of the sleeve, the rolling friction between the steel ball and the valve stem on the contact surface is much smaller than the sliding friction between the valve stem and the sleeve on the contact surface. Therefore, the valve stem can be raised and lowered in the sleeve faster by the rolling of the steel ball, further improving the response speed.

[0021] 3. In the present invention, by limiting the position of the slot in the sleeve and the position of the round rod when the block is engaged in the slot, no matter where the valve core is located or what the opening of the valve body is, when it is necessary to control the valve stem to rise and fall independently, there is space for the valve stem to move, and the problem of the valve body opening not being able to be quickly adjusted will not occur.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 9 As shown, the present invention is a novel intelligent throttle valve device, comprising:

[0035] A valve body 1, in which a valve seat 3 is fixedly installed, and a valve cover 2 is fixedly installed on the top, a valve stem 8 is slidably installed in the valve cover 2, and a bracket 5 is fixedly installed on the top, a clamping block 801 is fixedly installed on the valve stem 8, and a valve core 9 is fixedly installed on the bottom end, and the vertical position of the valve core 9 relative to the valve seat 3 is the opening, a fixed cylinder 6 is fixedly installed on the top of the bracket 5, a driving component 11 and a transmission component 16 are arranged in the fixed cylinder 6, and the transmission component 16 drives the valve stem 8 to reciprocate, a support plate 7 is fixedly installed in the fixed cylinder 6, and a first gear ring 19 is rotatably installed at the bottom of the support plate 7, and the first gear ring 19 is driven to reciprocate by the driving component 11;

[0036] A control component 4, which is disposed on the valve body 1 and is connected to the drive component 11 and the transmission component 16, and is used to determine whether the opening size of the valve body 1 is appropriate and whether the opening size needs to be urgently adjusted and make corresponding adjustments. The control component 4 is connected to the intelligent electric actuator; and

[0037] The sleeve 10 is slidably mounted on the support plate 7, and a thread groove 20 is provided on its surface. The thread groove 20 is threadedly connected to the inner ring of the first gear ring 19. A telescopic member 15 is fixedly mounted on the sleeve 10. The telescopic member 15 is used to drive the valve stem 8 to rise and fall, and is connected to the intelligent electric actuator. A card slot 12 and a slide groove 13 are provided in the sleeve 10. When the transmission assembly 16 drives the valve stem 8 to reciprocate, when the card block 801 is rotated into the card slot 12, the valve stem 8 is engaged with the sleeve 10, and the valve stem 8 and the sleeve 10 are lifted and lowered synchronously to adjust the opening size normally; when the card block 801 is rotated into the slide groove 13, the valve stem 8 is slidably connected to the sleeve 10. At this time, the valve stem 8 is lifted and lowered alone to adjust the opening size urgently.

[0038] Among them, the inlet end of the valve body 1 is connected to the gas wellhead device, the outlet end of the valve body 1 is connected to the manifold outlet, the control component 4 includes a first pressure sensor 401, a temperature sensor 402, a flow meter 403, a second pressure sensor 404 and a pressure relief screw assembly 405, and each component in the control component 4 is connected to the intelligent electric actuator through an explosion-proof cable; the telescopic member 15 can be selected from electric telescopic rods, electric cylinders and other components, and other mechanisms that can achieve lifting and lowering movements can also be selected, and this embodiment is not specifically limited here; it should be noted that the above-mentioned components are all prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0039] In actual application of this embodiment, the casing pressure, oil pressure, pipe pressure, temperature, flow rate and other data of the valve body 1 can be obtained through the first pressure sensor 401, the temperature sensor 402, the flow meter 403, the second pressure sensor 404 and the pressure relief screw assembly 405, and the intelligent electric actuator will judge whether the opening size of the valve body 1 is appropriate and whether the opening size needs to be adjusted urgently based on these data; when the data fluctuates within the threshold range, the opening size of the valve body 1 needs to be adjusted normally. At this time, the intelligent electric actuator drives the valve stem 8 to rotate through the transmission assembly 16, so that the block 801 on the valve stem 8 is inserted into the groove 12 on the inner wall of the sleeve 10, so as to Figure 3 Taking the direction shown as an example, the control drive component 11 drives the first gear ring 19 to rotate clockwise. Since the first gear ring 19 is threadedly connected to the thread groove 20, the sleeve 10 will rise under the action of the first gear ring 19. At this time, the sleeve 10 will drive the valve stem 8 to rise synchronously, and the valve core 9 rises, and the opening of the valve body 1 increases; conversely, the first gear ring 19 rotates counterclockwise, the sleeve 10 and the valve stem 8 fall synchronously, the valve core 9 falls, and the opening of the valve body 1 decreases. This method enables the sleeve 10 to achieve a small rise and fall each time through the precise cooperation between the thread groove 20 and the first gear ring 19, so that the opening size of the valve body 1 can be finely adjusted. In combination with the data obtained by the control component 4, the valve body 1 can be at a suitable opening size, thereby improving the accuracy of the adjustment;

[0040] When the data exceeds the threshold range, it is necessary to urgently adjust the opening of the valve body 1. At this time, the intelligent electric actuator drives the valve stem 8 to rotate through the transmission component 16, so that the block 801 on the valve stem 8 moves out of the card slot 12 on the inner wall of the sleeve 10. At this time, the block 801 slides in the slide slot 13 to Figure 2 Taking the direction shown as an example, when the intelligent electric actuator controls the telescopic part 15 to extend, the telescopic part 15 will drive the valve stem 8 to rise. At this time, the valve stem 8 is slidingly connected to the sleeve 10, and the valve core 9 rises synchronously, and the opening of the valve body 1 increases rapidly; on the contrary, when the telescopic part 15 contracts, the valve stem 8 and the valve core 9 descend synchronously, and the opening of the valve body 1 decreases rapidly. This is different from driving the valve stem 8 and the valve core 9 to rise and fall by the sleeve 10. The opening size of the valve body 1 can be precisely adjusted. In this way, the valve stem 8 and the valve core 9 can be driven to rise or fall rapidly, and the valve body 1 can be fully opened or fully closed in a short time. The emergency situation of the valve body 1 can be responded to in time, avoiding the situation where the time of handling risks is increased due to the inability to fully open or close quickly, resulting in additional risks.

[0041] like Figure 8 As shown, as a preferred embodiment of the present invention, the distance between the slot 12 and the top plate of the sleeve 10 is consistent with the distance between the slot 12 and the bottom plate of the sleeve 10, and both are not less than the maximum distance between the valve core 9 and the valve seat 3.

[0042] In actual application of this embodiment, when the valve stem 8 is engaged with the sleeve 10, that is, the block 801 is located in the slot 12, if the valve core 9 and the valve seat 3 are fully closed, the valve body 1 needs to be fully opened at this time, then the distance between the slot 12 and the top plate of the sleeve 10 is sufficient to allow the valve stem 8 to fully move upwards, thereby achieving a rapid full opening effect; conversely, if the distance between the valve core 9 and the valve seat 3 is at a maximum, the distance between the slot 12 and the bottom plate of the sleeve 10 is sufficient to allow the valve stem 8 to fully move downwards, thereby achieving a rapid full closing effect. This design can avoid the problem that the sleeve 10 is located at different heights, resulting in the valve stem 8 being unable to be fully raised or lowered.

[0043] like Figure 8 As shown, as a preferred embodiment of the present invention, a plurality of steel balls 14 are rotatably installed in the sleeve 10 , the plurality of steel balls 14 have different heights and are arranged circumferentially, and the valve stem 8 and the steel balls 14 are in rolling cooperation.

[0044] In actual application of this embodiment, by adding a steel ball 14 to the inner wall of the sleeve 10, the rolling friction between the steel ball 14 and the valve stem 8 on the contact surface is much smaller than the sliding friction between the valve stem 8 and the sleeve 10 on the contact surface. Therefore, the rolling of the steel ball 14 can make the valve stem 8 rise and fall in the sleeve 10 faster, further improving the response speed.

[0045] like Figure 2-Figure 3 As shown, as a preferred embodiment of the present invention, the driving assembly 11 includes a first gear 1101, a servo motor 1102, a U-shaped block 1103 and a limit block 1104. The first gear 1101 is rotatably installed at the bottom of the support plate 7, meshing with the first gear ring 19, and is driven to reciprocate by the servo motor 1102 installed on the top of the support plate 7. The servo motor 1102 is connected to the intelligent electric actuator. The two U-shaped blocks 1103 are respectively arranged on both sides of the sleeve 10, and both of them are fixedly connected to the bottom plate of the fixed cylinder 6. The two limit blocks 1104 are respectively fixedly installed at the bottom end of the sleeve 10, and both are slidably connected to the grooves of the two U-shaped blocks 1103.

[0046] In one case of this embodiment, it should be noted that the servo motor 1102 described in the present invention is a prior art, and the present invention does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0047] In actual application of this embodiment, when the servo motor 1102 drives the first gear 1101 to rotate, due to the meshing relationship between the first gear 1101 and the first gear ring 19, the first gear ring 19 will rotate synchronously with the first gear 1101, and the limit block 1104 at the bottom of the sleeve 10 is limited to slide in the groove of the U-shaped block 1103. Therefore, under the action of the first gear ring 19 and the threaded groove 20, the sleeve 10 can be lifted and lowered, thereby realizing the basic function of adjusting the opening size of the valve body 1.

[0048] like Figure 2-Figure 3 As shown, as a preferred embodiment of the present invention, the transmission assembly 16 includes a round rod 1601, a U-shaped frame 1602, a second gear ring 1603 and a second gear 1604, the round rod 1601 is fixedly mounted on the top of the valve stem 8, the second gear ring 1603 and the second gear 1604 are both rotatably mounted on the top of the support plate 7, and the second gear ring 1603 is meshed with the second gear 1604, an output source for driving the second gear 1604 to reciprocate is installed in the fixed cylinder 6, the output source is connected to the intelligent electric actuator, the U-shaped frame 1602 is fixedly mounted on the second gear ring 1603, and one end of the round rod 1601 is located in the U-shaped frame 1602.

[0049] In one case of this embodiment, the output source may be a servo motor, a motor component, or other mechanisms capable of achieving reciprocating rotational motion, which is not specifically limited in this embodiment.

[0050] In practical application, this embodiment is based on Figure 2 Taking the direction shown as an example, when the data obtained by the control component 4 exceeds the threshold range, the intelligent electric actuator immediately controls the output source to drive the second gear 1604 to rotate clockwise, thereby driving the second gear ring 1603 to rotate. The second gear ring 1603 is preset to rotate 30 degrees. At this time, the U-shaped frame 1602 on the second gear ring 1603 will drive the round rod 1601 to change its position. At this time, the U-shaped frame 1602 and the round rod 1601 slide relative to each other, and the valve stem 8 will rotate 30 degrees clockwise synchronously driven by the change in the position of the round rod 1601. At this time, the block 801 will turn away from the slot 12 and enter the slide slot 13; then the intelligent electric actuator controls the telescopic part 15 to extend and retract, thereby driving the valve stem 8 to rise and fall separately, thereby realizing rapid adjustment of the opening size of the valve body 1.

[0051] like Figure 2 As shown, as a preferred embodiment of the present invention, when the block 801 is located in the slot 12, the distance between the round rod 1601 and the top of the sleeve 10 is consistent with the distance between the round rod 1601 and the top plate of the fixed cylinder 6, and both are not less than the maximum distance between the valve core 9 and the valve seat 3.

[0052] In actual application of this embodiment, when the valve stem 8 is engaged with the sleeve 10, that is, the block 801 is located in the slot 12, if the valve core 9 and the valve seat 3 are fully closed, the valve body 1 needs to be fully opened at this time, then the distance between the round rod 1601 and the top plate of the fixed cylinder 6 is sufficient to allow the valve stem 8 to fully move upwards, thereby achieving a rapid full opening effect; conversely, if the distance between the valve core 9 and the valve seat 3 is at a maximum, the distance between the round rod 1601 and the top of the sleeve 10 is sufficient to allow the valve stem 8 to fully move downwards, thereby achieving a rapid full closing effect. This design can avoid the problem that the round rod 1601 blocks the valve stem 8 from fully rising and falling.

[0053] like Fig. 9 As shown, as a preferred embodiment of the present invention, an arc groove 21 is formed on the top of the valve stem 8 , and an I-shaped block 22 is fixedly mounted on the movable end of the telescopic member 15 , and the I-shaped block 22 is slidably matched with the arc groove 21 .

[0054] In actual application of this embodiment, due to the characteristics of the I-shaped block 22, the width of its upper and lower ends is greater than the width of the arc groove 21. Therefore, when the telescopic member 15 is extended and retracted, the I-shaped block 22 will drive the valve stem 8 to rise and fall synchronously, and when the valve stem 8 rotates under the action of the transmission assembly 16, the middle section of the I-shaped block 22 will slide in the arc groove 21 to avoid motion interference.

[0055] like Figure 6 As shown, as a preferred embodiment of the present invention, an annular O-ring 17 and a gasket 18 are fixedly installed on the valve seat 3, and the O-ring 17 is located above the gasket 18, and both are in contact with the inner wall of the valve body 1. The O-ring 17 and the gasket 18 can improve the sealing performance between the valve seat 3 and the valve body 1.

[0056] Working principle of the present invention: A new type of intelligent throttle valve device is provided in the above-mentioned embodiment of the present invention. The sleeve pressure, oil pressure, pipe pressure, temperature, flow rate and other data of the valve body 1 are obtained through the control component 4, and the intelligent electric actuator will judge whether the opening size of the valve body 1 is appropriate and whether the opening size needs to be urgently adjusted based on these data. When the data fluctuates within the threshold range, the opening size of the valve body 1 needs to be adjusted normally. At this time, the intelligent electric actuator drives the valve stem 8 to rotate through the transmission component 16, so that the block 801 on the valve stem 8 is inserted into the groove 12 on the inner wall of the sleeve 10. Through the precise cooperation between the thread groove 20 and the first gear ring 19, the sleeve 10 can achieve a small lift each time, so that the opening size of the valve body 1 can be adjusted. By making slight adjustments, and cooperating with the data obtained by the control component 4, the valve body 1 can be at an appropriate opening size, thereby improving the accuracy of the adjustment; when the data exceeds the threshold range, it is necessary to urgently adjust the opening size of the valve body 1. At this time, the intelligent electric actuator drives the valve stem 8 to rotate through the transmission component 16, so that the block 801 on the valve stem 8 moves out of the groove 12 on the inner wall of the sleeve 10. At this time, the block 801 slides in the slide groove 13, and the valve stem 8 and the valve core 9 can be driven to rise or fall rapidly through the telescopic member 15, so that the valve body 1 can be fully opened or fully closed in a short time, and the emergency situation of the valve body 1 can be responded to in time, avoiding the situation where the failure to quickly fully open or fully close causes an increase in the time of handling risks, resulting in additional risks.

[0057] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
