Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flow velocity measurement, in particular to a balancing orifice plate with adjustable aperture. Background Art

[0002] For media such as gas and liquid, the flow rate and flow velocity are generally detected through pressure difference, which is then calculated with a flow meter.

[0003] However, each gas or liquid has a different pressure and carries different amounts of dirt. The current treatment method is generally to directly replace the balancing orifice plate to adapt to the flow of the medium in the pipeline. However, when replacing the orifice plate, if the pipeline is carrying some pollutant media, the transportation can only be stopped and then the orifice plate can be replaced. This method is indeed effective in preventing gas leakage, but it hinders corporate production. However, for some pipelines that cannot stop the medium transportation, if the orifice plate is replaced, it is very easy to cause medium leakage, causing damage to the environment and the workers' health.

[0004] Therefore, how to provide a balancing orifice plate with adjustable aperture to solve the inconvenience of replacing the existing orifice plate is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] To this end, the utility model provides a balancing orifice plate with adjustable aperture to solve the problem in the prior art that the replacement operation of the balancing orifice plate requires stopping the medium transportation, which causes the enterprise's production efficiency to decrease and affects the benefits.

[0017] A limiting member has one end mounted on the other end of the moving rod, and the other end of the limiting member passes through the side surface of the circular connecting member.

[0019] A rotating handle, with a rotating rod connected to the surface of one end;

[0020] A thread is provided on the side surface of the rotating rod;

[0021] One end of the insertion rod is installed on the other end surface of the rotating rod, and a rotating block is installed on the other end surface of the insertion rod. A part of the insertion rod and the rotating block are inserted in the moving rod.

[0022] In a possible implementation, a rotation groove and a slot are formed in one end of the moving rod, and one end of the limiting member is inserted into the rotation groove and the slot.

[0023] In a possible implementation, the flow direction regulating component includes:

[0026] In a possible implementation, the annular connector includes:

[0027] A circular ring plate, with a slide groove formed inside, the slide groove extending inwardly to the inner ring surface of the circular ring plate;

The sliding design of the flow direction regulating assembly in the mounting part is to solve the problems of different pressures and impurities carried by the medium during flow. When the medium contains more impurities, splicing the flow direction regulating assemblies together can effectively block the impurities and prevent the orifice plate from being blocked. For the flow of high-pressure media, the orifice plate needs to be erosion-resistant. At this time, the flow direction regulating assemblies are spliced ​​together to extend the flow path, and the pressure is distributed to the flow direction regulating assemblies to prevent the pressure from being applied to the reducer assembly to cause damage to it. This not only improves the application range of the balancing orifice plate, but also avoids the operation of replacing the orifice plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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.

[0044] Please refer to Figure 1-Figure 6 Now, a balanced orifice plate with adjustable aperture disclosed in the utility model is described. The utility model is composed of four parts, such as Figure 1 , including a flow direction regulating component 1, a mounting member 2, a circular ring connector 3 and a reducing component 4. The circular ring connector 3 is installed in the throttling device. The mounting members 2 are arranged in pairs and are installed at the front and rear ends of the circular ring connector 3. The other end of the mounting member 2 is connected to the throttling device tube body. One end of a plurality of reducing components 4 is transmission-connected to the circular ring connector 3, and the other end extends outward along the circular ring connector 3 and passes through the side surface of the circular ring connector 3. A plurality of flow direction regulating components 1 are transmission-connected to the mounting member 2. The outer ends of the flow direction regulating components 1 are connected together to form a ring, and the ring is clamped on the outer surface of the mounting member 2.

[0045] When the utility model is in use, the entire balancing orifice plate is installed in the throttling device through the outer sides of the two mounting parts 2. For high-pressure gas, because of its high pressure, the impact force on the annular connector 3 is strong. As shown in the figure, assuming that the medium flows from front to back, the four flow direction regulating components 1 in the mounting part 2 behind the annular connector 3 are moved to be spliced ​​together. The four reducing plates 12 are spliced ​​together to form a small annular ring, and the inner diameter of the annular connector 3 is smaller than the inner diameter of the annular connector 3. At this time, part of the impact force will be transferred to the small annular ring, which reduces the impact force on the annular connector 3 and prolongs the service life of the entire orifice plate. As for impurities in the fluid or gas medium, when the impurities pass through the orifice plate, When the impurities hit the annular connector 3, there will be some residue. If the medium flow rate is fast at this time, the impurities may be washed away. However, if the flow rate is too slow, more impurities will accumulate. The accumulated impurities will affect the pressure difference signal, and then affect the flow rate detection. For the presence of impurities in this medium flow, assuming that the medium flows from front to back, at this time, the four flow direction adjustment components 1 in the mounting part 2 in front of the annular connector 3 are moved to splice together. The four reducers 12 are spliced ​​together to form a small annular ring. The inner diameter of this annular ring is smaller than the inner diameter of the annular connector 3. At this time, the annular ring will intercept the impurities, so that the impurities flowing to the annular connector 3 are reduced to prevent the accumulation of impurities. For the different media generated, the pressure is different, so it is necessary to move the reducer 4 to change the medium flow area to make the pressure difference more obvious.

[0046] In a specific embodiment, Figure 2 The reducing assembly 4 includes a limit member 41, a moving rod 42, a telescopic kit 43 and a reducing arc 44. The reducing arc 44 is transmission-connected in the circular ring connector 3. The telescopic kits 43 are arranged in pairs and are transmission-connected at both ends of the reducing arc 44. A spring is arranged between the reducing arc 44 and the telescopic kit 43. The telescopic kit 43 is transmission-connected in the circular ring connector 3. One end of the moving rod 42 is installed on the outer arc surface of the reducing arc 44. One end of the limit member 41 is installed on the other end of the moving rod 42. The other end of the limit member 41 passes through the side surface of the circular ring connector 3. The movable rod 42 is pulled to move by rotating the limiter 41. When the movable rod 42 moves, the reducing arc 44 moves along the trapezoidal block 31, so that the medium flow area changes. When the reducing arc 44 moves inward, the two telescopic kits 43 will move along the reducing arc 44. At this time, the spring contracts, and its elastic effect enables the reducing assembly 4 to be better clamped between the two trapezoidal blocks 31.

[0047] Based on the previous embodiment, Figure 3The limiting member 41 includes a rotating handle 411, a rotating rod 412, a rotating block 413, a plug rod 414 and a thread 415. The rotating handle 411 is connected to the rotating rod 412 on one end surface, and the thread 415 is provided on the side surface of the rotating rod 412. One end of the plug rod 414 is mounted on the other end surface of the rotating rod 412, and the rotating block 413 is mounted on the other end surface of the plug rod 414. A part of the plug rod 414 and the rotating block 413 are inserted into the moving rod 42. The internal thread in the annular connector 3 cooperates with the thread 415, so that the entire limiting member 41 can move inside or outside the annular connector 3. When the rotating handle 411 is driven to rotate, the rotating rod 412 and the rotating block 413 will be driven to rotate. When the limiting member 41 rotates, it will move along the internal thread of the annular connector 3. At this time, the limiting member 41 will also pull the moving rod 42 to move.

[0048] On the basis of the previous embodiment, a rotation groove and a slot are formed in one end of the moving rod 42, and one end of the stopper 41 is inserted into the rotation groove and the slot. The rotation groove is provided to facilitate the rotation of the stopper 41.

[0049] In a specific embodiment, Figure 4 The flow direction regulating assembly 1 comprises a transmission rod 11, a reducing plate 12, a block 13, a connecting arc 14 and a slot 15. The transmission rod 11 is connected to the side wall of the mounting member 2. The reducing plate 12 is installed at one end of the transmission rod 11. The connecting arc 14 is installed at the other end of the transmission rod 11. The blocks 13 and the slots 15 are respectively arranged on the surfaces of both ends of the connecting arc 14. The transmission rod 11 is driven to move by pushing the connecting arc 14. The transmission rod 11 will push the reducing plate 12 to move. When four of the blocks 13 are inserted into the four slots 15, the four connecting arcs 14 will be connected into a ring. At the same time, the plug-in structure can make the four flow direction regulating assemblies 1 stably connected and easy to separate.

[0050] In a specific embodiment, Figure 5 The annular connector 3 includes a trapezoidal block 31, an annular plate 32, a slide groove 33 and a moving groove 34. The annular plate 32 has a slide groove 33 inside, which extends inward to the inner surface of the annular plate 32. One end surface of a plurality of trapezoidal blocks 31 is attached to the inner surface of the annular plate 32. One end of the trapezoidal block 31 is installed in the slide groove 33. The moving groove 34 is provided in the annular plate 32. One end of the moving groove 34 extends to the slide groove 33, and the other end of the moving groove 34 passes through the outer surface of the annular plate 32. An internal thread structure is provided at the moving groove 34 near the outer edge of the annular plate 31, and the moving rod 34 is used to move the stopper 41 and the moving rod 42.

[0051] In a specific embodiment, Figure 6The mounting member 2 includes a mounting shell 21 and a stopper 22. The mounting shell 21 is mounted on one end surface of the circular connecting member 3. The mounting shell 21 is provided with a plurality of circular holes. A plurality of stopper blocks 22 are mounted on the inner surface of the mounting shell 21. A stopper space is formed between the two stopper blocks 22 and the inner surface of the mounting shell 21. The stopper space is clamped with the reducing plate 12. When the reducing plate 12 is not required, the reducing plate 12 is arranged in the restricted space, which can effectively prevent the leakage of the medium. After the reducing plate 14 is attached to the outer surface of the mounting member 2 on one side, the leakage of the medium can also be effectively prevented.
