Description

Technical Field

[0001] The present invention relates to the field of fluid machinery, and in particular to an integrated orifice plate device. Background Art

[0002] The working principle of the sonic orifice plate is based on the Bernoulli equation and the principles of fluid dynamics. When the fluid flows through the orifice plate, there is a certain pressure difference before and after the orifice plate. For a certain aperture, the flow rate through the orifice plate increases with the increase of the pressure difference. However, when the pressure difference exceeds a certain value, the flow velocity of the fluid through the orifice plate contraction reaches the speed of sound. At this time, no matter how the pressure difference increases, as long as the pressure upstream of the orifice plate remains constant, the flow rate through the orifice plate will remain at a certain value and will no longer increase. The sonic orifice plate structure is widely used in chemical, petroleum, metallurgy and other fields. By utilizing the beam effect of the circular hole in the middle of the thin plate in the pipeline, the fluid flow control can be conveniently achieved by measuring the pressure difference before and after the orifice plate.

[0003] However, when the fluid contains powder or other solid impurities, the small-sized orifice plate is prone to clogging and must be restored to function by unclogging or replacing the orifice plate. In the existing technology, unclogging or replacing the orifice plate must be performed during shutdown, which affects production continuity on the one hand and the shutdown and restart cycle of the complex chemical system is long and the operation is complicated on the other hand. In addition, unclogging or replacing the orifice plate requires disassembling the system, which may pose a safety hazard if there are toxic or radioactive media in the system.

[0004] Therefore, an integrated orifice plate device is urgently needed to solve the technical problem of online unclogging of the orifice plate without stopping the system. Summary of the Invention

[0054] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0055] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides an integrated orifice plate device, comprising:

[0056] The housing 1 has a boss 11 formed on the side of the housing 1, and the boss 11 is plugged and connected to the inside of the input pipe 2;

[0057] A first chamber 12 and a second chamber 13 are provided along the axis of the housing 1. The first chamber 12 is connected to the output pipe 3. A third chamber 14 is formed inside the boss 11. A first side of the third chamber 14 is connected to the input pipe 2, and a second side of the third chamber 14 is connected to the sidewall of the second chamber 13.

[0058] A sonic orifice plate 16 formed inside the housing 1, the sonic orifice plate 16 being disposed between the first chamber 12 and the second chamber 13, and a first through-hole 161 formed on a surface of the sonic orifice plate 16, through which the first chamber 12 and the second chamber 13 are connected;

[0059] A mounting tube 17 formed on the side of the housing 1 , wherein a fourth chamber 15 is provided inside the mounting tube 17 , and the fourth chamber 15 is located on a side of the second chamber 13 away from the first chamber 12 ;

[0060] A slider 5 is slidably disposed in the fourth chamber 15 , and a dredging rod 51 is formed at the front end of a first side of the slider 5 ;

[0061] A first baffle 4 is fixedly mounted on a first side of the fourth chamber 15 , wherein a second through hole 41 is provided on the first baffle 4 , and the second chamber 13 and the fourth chamber 15 are connected via the second through hole 41 , and the axes of the dredging rod 51 , the first through hole 161 , and the second through hole 41 coincide with each other;

[0062] a driving device for controlling the sliding block 5 to slide in the fourth chamber 15;

[0063] When the driving device controls the slider 5 to approach the first baffle 4, the dredging rod 51 passes through the second through hole 41 and is inserted into the first through hole 161. When the driving device controls the slider 5 to move away from the first baffle 4, the dredging rod 51 disengages from the first through hole 161.

[0064] In this embodiment, the working principle of the sonic orifice plate 16 is based on the Bernoulli equation and the principle of fluid dynamics. When the fluid flows through the orifice plate, there is a certain pressure difference before and after the orifice plate. For a certain aperture, the flow rate through the orifice plate increases as the pressure difference increases. However, when the pressure difference exceeds a certain value, the flow rate of the fluid through the orifice plate shrinkage reaches the speed of sound. The present invention forms the sonic orifice plate 16 inside the shell 1. The shell 1 is used to protect the internal structure and provide installation space for other components. The boss 11 is formed on the side of the shell 1 for plug connection with the input pipe 2 and fixed by bolts, which improves the stability of the device. The sonic orifice plate 1 6 is arranged between the first chamber 12 and the second chamber 13, the first chamber 12 is connected to the low-pressure area through the output pipe 3, the second chamber 13 and the third chamber 14 are connected to the high-pressure area through the input pipe 2, the second chamber 13 and the third chamber 14 are connected to each other and are perpendicular to each other. In order to prevent the high-pressure water flow from directly rushing towards the slider 5 or the orifice plate, it plays a certain buffering role and improves the reliability of the operation of the device. The fourth chamber 15 arranged inside the mounting tube 17 is used to carry the slider 5. The internal clearance of the slider 5 and the fourth chamber 15 are matched, so that the slider 5 can The first baffle 4, which is freely movable in the horizontal direction and fixedly mounted on the first side of the fourth chamber 15, is used to horizontally limit the maximum distance that the slider 5 moves toward the first side of the fourth chamber 15, thereby preventing the dredging rod 51 from touching the inner wall of the shell 1 and damaging the structure, thereby increasing the safety of the equipment. Preferably, a washer is provided at the first end of the slider 5 to prevent the slider 5 from completely fitting with the first baffle 4, thereby achieving the effect of buffering the force. The dredging rod 51 is formed at the front end of the first side of the slider 5. When the driving device controls the slider 5 to approach the first baffle 4, the dredging rod 51 penetrates The second through hole 41 is inserted into the first through hole 161. When the driving device controls the slider 5 to move away from the first baffle 4, the dredging rod 51 is disengaged from the first through hole 161, and is used to enter and exit the first through hole 161 to achieve dredging of the sonic orifice 16. The second through hole 41 is provided on the first baffle 4, and the second chamber 13 and the fourth chamber 15 are connected through the second through hole 41. Since the axes of the dredging rod 51, the first through hole 161 and the second through hole 41 coincide, the second through hole 41 is used to provide a guide for the dredging rod 51, thereby reducing working errors.

[0065] Under one solution, the driving device controls the slider 5 to reciprocate once at a preset time interval to achieve the dredging work of the sonic orifice 16. This solution can effectively save working costs; under another solution, a flow sensor is set on the output pipe 3. Due to the characteristics of the sonic orifice 16, the flow flowing into the output pipe 3 through the sonic orifice 16 is a constant preset flow. The flow sensor is electrically connected to the controller, and the controller is electrically connected to the driving device. The flow sensor is used to monitor the flow size in the output pipe 3 in real time. When the actual flow is less than the preset flow, the controller controls the driving device to drive the slider 5 to reciprocate. When the actual flow is restored to the preset flow, the slider 5 is controlled to return to its original position and stop moving. This solution can accurately achieve the dredging work and ensure the effect of the dredging operation. In actual application, the corresponding control scheme is flexibly selected according to the on-site conditions, which improves the flexibility of equipment application. In summary, the present invention solves the technical problem of online dredging of orifice plate blockage without shutting down the system through the mutual cooperation of the one-piece formed orifice plate and the cavity.

[0066] like Figure 1 As shown, in an optional embodiment of the present invention, a sealing ring 411 is provided on the first side of the second through hole 41 , and the surface of the sealing ring 411 is formed with a through hole having the same diameter as the dredging rod 51 .

[0067] In this embodiment, since the second cavity and the third cavity are filled with pressurized liquid, and a clearance fit is adopted between the dredging rod 51 and the second through hole 41 to ensure the free sliding of the dredging rod 51 in the direction of movement, the sealing ring 411 is provided to block the connection between the second cavity and the fourth cavity, thereby preventing the pressurized liquid from entering the fourth cavity from the clearance between the dredging rod 51 and the second through hole 41, hindering the movement of the slider 5, and further improving the reliability of the equipment operation.

[0068] like Figure 1 、 Figure 2 As shown, in an optional embodiment of the present invention, the slider 5 is made of a magnetic conductive material, and the housing 1 is made of a non-magnetic conductive material;

[0069] The driving device comprises:

[0070] An annular magnetic steel 6 is sleeved on the middle part of the mounting tube 17;

[0071] A first coil 71, which is wound around the surface of the mounting tube 17 and is located on a first side of the annular magnetic steel 6;

[0072] A second coil 81, the second coil 81 is wound on the surface of the mounting tube 17, and the second coil 81 is located on the second side of the annular magnetic steel 6;

[0073] The winding directions of the first coil 71 and the second coil 81 are consistent.

[0074] In this embodiment, an electromagnetic drive slider 5 is used to perform reciprocating motion, that is, the relative motion of the magnetic field generates an electric current in the magnetic material, and the current causes the magnetic material to be acted upon by the Ampere force to cause the magnetic material to move. The slider 5 is made of magnetic material and is used to perform reciprocating motion under the action of the magnetic field. The shell 1 is made of non-magnetic material and will not generate electromagnetic drive, will not interfere with the movement path of the slider 5, and at the same time plays a bearing role.

[0075] The annular magnet 6 is a permanent magnet that continuously generates magnetic fields of equal strength and opposite directions on both sides. The first side of the annular magnet 6 generates a positive magnetic field, and the second side of the annular magnet 6 generates a negative magnetic field. Since the magnetic field strengths on both sides are the same, the slider 5 is kept stationary under the influence of the magnetic field when it is at both ends of the fourth chamber 15, thereby improving the stability of the device.

[0076] The first coil 71 is wound around the surface of the mounting tube 17, and the second coil 81 is wound around the surface of the mounting tube 17, forming two electromagnets that generate a magnetic field only when energized. The direction of the current in the electromagnet determines the direction of the generated magnetic field. The winding directions of the first coil 71 and the second coil 81 are consistent, ensuring that the first coil 71 and the second coil 81 generate magnetic fields in the same direction when energized. The direction of the current flowing into the first coil 71 and the second coil 81 is controlled by a control system. The control system provides two parallel power supplies with opposite positive and negative poles. The positive power supply is connected to a first switch to control the connection and disconnection of the positive circuit, and the negative power supply is connected to a second switch to control the connection and disconnection of the negative circuit. At least one of the first switch and the second switch is in the off state. Preferably, only one power supply is provided, and the change of the current direction is controlled by a preset program of the electronic circuit. The magnetic field strength generated by the first coil 71 or the second coil 81 is greater than the magnetic field strength generated by the annular magnet 6. The first coil 71 is located on the first side of the annular magnet 6, and the second coil 81 is located on the second side of the annular magnet 6, so as to improve the stability of the movement of the slider 5.

[0077] When a current in the first direction is applied, the first coil 71 generates a first positive coil magnetic field, and the second coil 81 generates a second positive coil magnetic field. The first side of the annular magnetic steel 6 is a superposition of the positive magnetic steel magnetic field and the first positive coil magnetic field, and the superimposed magnetic field is positive. The second side of the annular magnetic steel 6 is a mutual cancellation of the negative magnetic steel magnetic field and the second positive coil magnetic field, so that the overall magnetic field strength of the first side of the annular magnetic steel 6 is greater than the magnetic field strength of the second side of the annular magnetic steel 6. Therefore, when a current in the first direction is applied, the slider 5 moves toward the first side of the fourth chamber 15 under the action of the superimposed magnetic fields on both sides.

[0078] When a current in the second direction is applied, the first coil 71 generates a first negative coil magnetic field, and the second coil 81 generates a second negative coil magnetic field. The positive magnetic field on the first side of the annular magnetic steel 6 and the first negative coil magnetic field cancel each other out, while the negative magnetic field and the second negative coil magnetic field are superimposed on the second side of the annular magnetic steel 6. This makes the overall magnetic field strength on the second side of the annular magnetic steel 6 greater than the magnetic field strength on the first side of the annular magnetic steel 6. Therefore, when a current in the second direction is applied, the slider 5 moves toward the second side of the fourth chamber 15 under the action of the superimposed magnetic fields on both sides.

[0083] The clamp 93 is disposed in an annular groove outside the mounting tube 17 , and the clamp 93 abuts against the sealing cover 92 .

[0084] In this embodiment, the sleeve 9 is sleeved on the outside of the mounting tube 17, and the first coil 71, the annular magnetic steel 6 and the second coil 81 are located in the sleeve 9; the first side of the sleeve 9 abuts against the shell 1, and the second side of the sleeve 9 is detachably connected to the cover 92 to isolate the first coil 71, the annular magnetic steel 6 and the second coil 81 from the external environment. The second side of the sleeve 9 is detachably connected to the cover 92 for easy maintenance and replacement, which improves the flexibility of the device. The sleeve 9 is fixed by the clamp 93 to further ensure the sealing of the sleeve 9, and at the same time, disassembly and assembly are convenient and quick.

[0085] like Figure 3 As shown, in an optional embodiment of the present invention, a long groove 91 extending to the second side of the sleeve 9 is opened on the upper surface of the sleeve 9.

[0086] In this embodiment, the long slot 91 is used to lead out the power connection ends of the first coil 71 and the second coil 81 .

[0090] In this embodiment, the first mounting seat 7 and the second mounting seat 8 are respectively used to prevent the first coil 71 and the second coil 81 from sliding axially, thereby further improving the stability of the system.

[0092] The first protruding engaging portion 711 and the second protruding engaging portion 811 are engaged with the long groove 91 .

[0093] In this embodiment, the first protruding clamping portion 711 and the second protruding clamping portion 811 are engaged with the long groove 91 to prevent the first mounting seat 7 and the second mounting seat 8 from rotating around the axis, thereby further improving the stability of the system.

[0094] like Figure 1 、 Figure 2 As shown, in an optional embodiment of the present invention, the integrated orifice plate device further includes:

[0095] A second baffle 10 is slidably mounted on the second side of the fourth chamber 15 , and a third through hole 101 is defined on a surface of the second baffle 10 ;

[0096] A sealing seat 102 for fixing the second baffle 10, wherein a protruding shaft 1021 is formed on a first side of the sealing seat 102, and the protruding shaft 1021 is plugged into and fitted with the third through hole 101;

[0097] The first side of the second baffle 10 abuts against the groove in the mounting tube 17 , and the second side of the second baffle 10 abuts against the first side of the sealing seat 102 ;

[0098] a first gasket 103 , the first gasket 103 being located in the fourth chamber 15 and abutting against the second side of the sealing seat 102 ;

[0099] The fastening bolt 104 is threadedly intercepted in the mounting tube 17 , and the fastening bolt 104 abuts against the first washer 103 .

[0100] In this embodiment, the second baffle 10 is used to horizontally limit the maximum distance that the slider 5 can move toward the second side of the fourth chamber 15, ensuring that the dredging rod 51 has no possibility of escaping from the second through hole 41, further increasing the safety of the equipment, and the sealing seat 102 is used to fix the second baffle 10, and the first side of the sealing seat 102 is formed with a convex shaft 1021 that is plugged into the third through hole 101 to make the fixing effect more firm.
