Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, and particularly relates to a bridge orifice plate flow meter. Background Art

[0002] Flow meters are used to measure the flow rate of gases or liquids in pipelines and are widely used in fields such as petrochemical industry. There are many types of flow meters. For example, gear flow meters, electromagnetic flow meters, and orifice plate flow meters. An orifice plate flow meter is a high-range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (such as a differential pressure transmitter, a temperature transmitter, and a pressure transmitter), and can measure the flow rate of gases, steam, liquids, and natural gas.

[0003] For this disclosed technology, in the existing bridge orifice plate flow meter, the orifice plate flow meter is connected to the measurement pipeline to measure the flow rate of the passing substance. However, for the structure of the bridge orifice plate flow meter for measuring the flow rate of petroleum, the measurement pipeline and the flow pipeline are mostly connected through flange plates. Since there will be gaps on the connecting surface of the flange plates, even if a sealing rubber gasket is added, oil leakage may still occur. These leaked oils directly drip onto the ground, which will not only cause pollution to the ground but also result in waste of petroleum resources.

[0004] Therefore, a bridge orifice plate flow meter is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that for the structure of the bridge orifice plate flow meter for measuring the flow rate of petroleum, the measurement pipeline and the flow pipeline are mostly connected through flange plates. Since there will be gaps on the connecting surface of the flange plates, even if a sealing rubber gasket is added, oil leakage may still occur. These leaked oils directly drip onto the ground, which will not only cause pollution to the ground but also result in waste of petroleum resources. The utility model provides a bridge orifice plate flow meter.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A bridge orifice flowmeter, comprising an orifice flowmeter main body, wherein a flow component is arranged on the surface of the orifice flowmeter main body, a hoisting component for recovering leaked liquid is arranged on the surface of the flow component, a recovery box is fixedly connected to the surface of the hoisting component, a connection component for recovering leaked liquid is arranged on the inner wall of the recovery box, an installation component is arranged on the surface of the connection component, a filter screen is fixedly connected to the inner wall of the installation component, a moving component for preventing blockage of the surface of the filter screen is arranged on the surface and inner wall of the connection component, a cleaning brush part is arranged on the surface of the moving component, a scraper is fixedly connected to the surface of the cleaning brush part, an opening is formed through the left side of the recovery box, a discharge pipe is arranged on the surface of the recovery box, a hoop is arranged on the surface of the flow component, and a rubber pad is fixedly connected to the inner wall of the hoop.

[0008] Further, the flow component includes a measurement pipeline. The measurement pipeline is arranged on the bottom surface of the orifice flowmeter main body. A flow pipeline is attached to the side surface of the measurement pipeline. A flange connection part is fixedly sleeved on the surfaces of the measurement pipeline and the flow pipeline, and the measurement pipeline and the flow pipeline are connected through the flange connection part.

[0009] Further, the hoisting component includes a sleeve rod. The sleeve rod is attached to the surface of the flow pipeline. An installation angle code is fixedly connected to the bottom surface of the sleeve rod, and the connection component is connected to the installation angle code.

[0010] Further, the connection component includes a connection block. The connection block is fixedly connected to the inner wall of the recovery box. A lapping block is fixedly connected to the surface of the connection block. A magnetic attraction block is fixedly connected to the inner wall of the lapping block.

[0011] Further, the installation component includes a metal mesh frame. The metal mesh frame is adsorbed on the top surface of the magnetic attraction block, and the filter screen is connected to the metal mesh frame. A lifting groove is formed on the top surface of the metal mesh frame.

[0012] Further, the moving component includes a motor. The motor is fixedly connected to the surface of the recovery box.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In this utility model, the recovery box is connected below the flow component through a hoisting component. When oil leaks at the connection of the flange plate connector, the recovery box can receive the leaked oil. The metal mesh frame is adsorbed and connected to the magnetic attraction block, so that the metal mesh frame is connected between the two connection blocks. At the same time, the metal mesh frame is fixed by adsorption. When disassembling and assembling the metal mesh frame, through the taking of the lifting groove, the disassembly and assembly of the metal mesh frame are more convenient.

After the cleaning brush component moves, it can sweep away the fine impurities on the surface of the filter screen. The setting of the scraper, the cleaning brush component drives the scraper to move. There is a gap between the bottom surface of the scraper and the surface of the filter screen. Therefore, the scraper only scrapes the impurities such as leaves, and the impurities such as leaves can be removed from the opening. The setting of the discharge pipe enables the recovered oil to be removed, thus completing the recovery work of collecting oil; through the sealing of the hoop, the flange connection is further sealed, so that it is not easy to have the problem of oil leakage.

[0023] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, a bridge orifice plate flowmeter includes an orifice plate flowmeter main body 1. A flow component 2 is provided on the surface of the orifice plate flowmeter main body 1. A hoisting component 3 for recovering leaked liquid is provided on the surface of the flow component 2. A recovery box 4 is fixedly connected to the surface of the hoisting component 3. A connection component 5 for recovering leaked liquid is provided on the inner wall of the recovery box 4.

A hoop 13 is provided on the surface of the flow component 2, and a rubber pad is fixedly connected to the inner wall of the hoop 13. Specifically, for this bridge orifice plate flowmeter, the flow component 2 is connected to the orifice plate flowmeter main body 1, and then the flow rate of the substance passing through the flow component 2 is measured by the orifice plate flowmeter main body 1. At the flange connection, a hoop 13 is additionally provided outside, and a rubber pad is attached to the inside of the hoop 13, so as to further seal the joint to prevent the problem of oil leakage. At the same time, if there is still leakage, the recovery box 4 is connected to the surface of the flow component 2 through the hoisting component 3. The recovery box 4 is directly below the flow component 2. If there is a leakage at the joint of the flow component 2 parts, the recovery box 4 can receive the leaked oil. The recovery box 4 is connected to the installation component 6 through the connection component 5, so that the installation component 6 can be disassembled and assembled conveniently. The filter screen 7 is connected to the inner wall of the installation component 6. The filter screen 7 can prevent external impurities from entering the recovery box 4. With the setting of the moving component 8, the moving component 8 drives the cleaning brush part 9 to move. When the cleaning brush part 9 passes through the surface of the filter screen 7, it can clean the surface of the filter screen 7, so that when the oil passes through the filter screen 7, the downward leakage effect of the oil will not be affected. The cleaning brush part 9 is connected with a scraper 10. When there are leaf-like impurities floating on the filter screen 7, the scraper 10 can scrape the impurities out through the opening 11. With the setting of the discharge pipe 12, the oil recovered in the recovery box 4 can be transferred out, so as to recycle the leaked oil. Through the seal of the hoop, the flange connection is further sealed, so that the problem of oil leakage is not likely to occur. At the same time, if there is still a leakage problem, the leaked oil can also be recycled at this time. At the same time, when receiving the oil, external impurities can be prevented from falling into the recovered oil, and the surface of the filter screen 7 can also be cleaned, so that the effect of the oil passing through the filter screen 7 will not be affected.

[0024] As Figure 2As shown in the figure, the flow component 2 includes a measuring pipeline 201. The bottom surface of the orifice flowmeter body 1 is provided with the measuring pipeline 201. A flow pipeline 202 is attached to the side surface of the measuring pipeline 201. A flange connection member 203 is fixedly sleeved on the surface of the measuring pipeline 201 and the surface of the flow pipeline 202. And the measuring pipeline 201 and the flow pipeline 202 are connected through the flange connection member 203. Specifically, the flow component 2 connects to the orifice flowmeter body 1. The orifice flowmeter body 1 is connected to the measuring pipeline 201. The flange connection member 203 connects and fixes the flow pipeline 202 and the measuring pipeline 201. When the petroleum liquid to be measured passes through the measuring pipeline 201, the orifice flowmeter body 1 measures the passing petroleum flow rate.

[0025] As Figure 1 shown in the figure, the hoisting component 3 includes a sleeve rod 301. The sleeve rod 301 is attached to the surface of the flow pipeline 202. The bottom surface of the sleeve rod 301 is fixedly connected with a mounting angle bracket 302. And the connection component 5 is connected to the mounting angle bracket 302. Specifically, the recovery box 4 is connected below the flow component 2 through the hoisting component 3. The sleeve rod 301 is attached to the surface of the flow pipeline 202. The recovery box 4 is fixedly connected to the sleeve rod 301 through the mounting angle bracket 302, so that the recovery box 4 is hoisted below the flow component 2. When petroleum leaks at the connection of the flange connection member 203, the recovery box 4 can receive the leaked petroleum.

[0026] As Figure 3 shown in the figure, the connection component 5 includes a connection block 501. The connection block 501 is fixedly connected to the inner wall of the recovery box 4. A lapping block 502 is fixedly connected to the surface of the connection block 501. A magnetic attraction block 503 is fixedly connected to the inner wall of the lapping block 502. Specifically, the connection component 5 is externally provided. The installation component 6 is connected inside the recovery box 4 through the connection component 5. The magnetic attraction block 503 is connected in the lapping block 502, and the magnetic attraction block 503 can connect to the installation component 6.

[0027] As Figure 3 shown in the figure, the installation component 6 includes a metal mesh frame 601. The metal mesh frame 601 is adsorbed on the top surface of the magnetic attraction block 503. And the filter screen 7 is connected to the metal mesh frame 601. A lifting groove 602 is opened on the top surface of the metal mesh frame 601. Specifically, due to the setting of the installation component 6, the metal mesh frame 601 is adsorbed and connected to the magnetic attraction block 503, so that the metal mesh frame 601 is connected between the two connection blocks 501. At the same time, the metal mesh frame 601 is fixed by adsorption. When the metal mesh frame 601 is disassembled and assembled, by taking it through the lifting groove 602, the disassembly and assembly of the metal mesh frame 601 are more convenient.

[0028] As Figure 1 、 Figure 2As shown in the figure, the moving component 8 includes a motor 801, the surface of the recycling box 4 is fixedly connected with the motor 801, the output end of the motor 801 is fixedly connected with a threaded rod 802, and the threaded rod 802 is rotatably connected with the recycling box 4. Moreover, the cleaning brush member 9 is threadedly connected with the threaded rod 802, and an auxiliary rod 803 is fixedly connected to the inner wall of the recycling box 4, and the cleaning brush member 9 is slidably connected with the auxiliary rod 803. Specifically, the setting of the filter screen 7 can prevent external impurities from falling into the recycling box 4. The setting of the moving component 8 enables the moving component 8 to drive the cleaning brush member 9 to move. When the motor 801 operates, the output end of the motor 801 drives the threaded rod 802 to rotate. At this time, with the cooperation of the auxiliary rod 803, the cleaning brush member 9 moves. After the cleaning brush member 9 moves, it can sweep away the fine impurities on the surface of the filter screen 7. The setting of the scraper 10 is such that the cleaning brush member 9 drives the scraper 10 to move. There is a gap between the bottom surface of the scraper 10 and the surface of the filter screen 7. Thus, the scraper 10 only scrapes the leaf-like impurities, and the leaf-like impurities can be removed from the opening 11. The setting of the discharge pipe 12 allows the recycled oil to be removed, thereby completing the recycling work of collecting the oil.

[0029] In summary: For this bridge orifice flowmeter, through the addition of the hoop 13, the hoop 13 further seals the flange connection, and thus it is not easy to have the problem of oil leakage. At the same time, if there is still a leakage problem, the recycling box 4 is connected below the flow component 2 through the lifting component 3. The sleeve rod 301 fits on the surface of the flow pipe 202, and the recycling box 4 is fixedly connected to the sleeve rod 301 through the mounting angle 302. When oil leaks at the connection of the flange plate connector 203, the recycling box 4 can receive the leaked oil. The recycling box 4 is connected with the mounting component 6 through the connection component 5. A magnetic block 503 is connected in the overlapping block 502, and the metal mesh frame 601 is adsorbed and connected to the magnetic block 503, so that the metal mesh frame 601 is connected between the two connecting blocks 501. At the same time, the metal mesh frame 601 is fixed by adsorption. When disassembling and assembling the metal mesh frame 601, by taking it through the lifting groove 602, it is more convenient to disassemble and assemble the metal mesh frame 601. The setting of the filter screen 7 can prevent external impurities from falling into the recycling box 4. The setting of the moving component 8 enables the moving component 8 to drive the cleaning brush member 9 to move. When the motor 801 operates, the output end of the motor 801 drives the threaded rod 802 to rotate. At this time, with the cooperation of the auxiliary rod 803, the cleaning brush member 9 moves. After the cleaning brush member 9 moves, it can sweep away the fine impurities on the surface of the filter screen 7. The setting of the scraper 10 is such that the cleaning brush member 9 drives the scraper 10 to move. There is a gap between the bottom surface of the scraper 10 and the surface of the filter screen 7. Thus, the scraper 10 only scrapes the leaf-like impurities, and the leaf-like impurities can be removed from the opening 11. The setting of the discharge pipe 12 allows the recycled oil to be removed, thereby completing the recycling work of collecting the oil.
