[0001] The utility model relates to the technical field of turbine flowmeters, in particular to a low-wear and corrosion-resistant turbine flowmeter. Background Art
[0002] The turbine flowmeter is a velocity flow meter with temperature and pressure compensation functions. It is a type of velocity flowmeter. Its working principle is: the power of the flowing fluid drives the turbine blades to rotate, and its rotation speed is approximately proportional to the volume flow rate. The fluid volume indication passing through the flowmeter is based on the number of revolutions of the turbine impeller. The turbine flowmeter is widely used in petroleum, chemical, electric power, gas pipeline networks, urban gas and other fields due to its high measurement accuracy, good repeatability and stability, wide measuring range, rapid response to flow changes, strong anti-interference ability, and easy signal transmission. It is also widely used in trade settlement and other fields. The turbine flowmeter has played a positive role in improving productivity in many contemporary fields.
[0003] Existing turbine flowmeters cannot effectively separate particulate impurities in fluid media. During long-term use, the internal structure of the turbine flowmeter is severely worn, which easily damages the corrosion-resistant layer on the surface of the internal structure of the flowmeter. The service life needs to be improved. Utility Model Content
[0004] The purpose of the utility model is to provide a low-wear and corrosion-resistant turbine flowmeter which can effectively separate particulate impurities in a fluid medium, effectively reduce the degree of wear of the internal structure of the flowmeter, and effectively increase the service life.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A low-wear, corrosion-resistant turbine flowmeter includes a detection seat, one end of which is integrally connected to a separation seat, a metal mesh is mounted on the inner side of the separation seat, and the metal mesh is in a circular ring shape. A plurality of guide plates are fixedly connected to the inner wall of the water inlet of the separation seat, and the guide plates are in a spiral shape.
[0007] By adopting the above technical solution, the particulate impurities in the fluid medium can be effectively separated, and the particulate impurities are prevented from entering the interior of the detection seat, thereby preventing the particulate impurities from causing wear to the internal structure of the detection seat.
[0008] Furthermore, a bracket is fixedly connected to the inner wall of the water inlet of the separation seat, and a permanent magnet steel is adsorbed on the side surface of the bracket.
[0009] By adopting the above technical solution, permanent magnetic steel can be used to absorb metal impurities in the fluid medium.
[0010] Furthermore, a discharge pipe is integrally connected to the bottom of the side surface of the separation seat, a valve is fixedly installed in the pipeline of the discharge pipe, and the inlet end of the discharge pipe is located on one side of the metal mesh.
[0011] By adopting the above technical solution, the discharge pipe can be controlled and operated by using the valve, and the collected particulate impurities can be discharged by using the discharge pipe.
[0012] Furthermore, two guide seats are snap-fitted onto the inner wall of the detection seat, and turbines are rotatably mounted on the two guide seats. A mounting hole is provided on the side surface of the detection seat, and a magnetic resistance induction structure is mounted on the internal thread of the mounting hole, and the magnetic resistance induction structure corresponds to the position of the turbine.
[0013] By adopting the above technical solution, it is ensured that the rotation of the turbine can effectively change the magnetic resistance and magnetic field of the magnetic resistance induction structure, thereby enabling the induction coil on the magnetic resistance induction structure to generate current, ensuring that the flow meter can effectively detect the flow data of the fluid medium.
[0014] Furthermore, a data processing unit is provided at one end of the magnetoresistive sensing structure, and the data processing unit is electrically connected to the magnetoresistive sensing structure.
[0015] By adopting the above technical solution, the current generated by the magnetoresistive induction structure can be effectively processed.
[0016] Furthermore, one end of the detection seat and the separation seat are both integrally connected with a flange.
[0017] By adopting the above technical solution, it is ensured that the flow meter can be effectively installed.
[0018] In summary, the beneficial technical effects of the present invention are:
[0019] When in use, the utility model can install the flow meter on the conveying pipeline so that the fluid medium enters the interior of the separation seat from one end of the separation seat. At this time, the permanent magnet steel adsorbed on the side surface of the bracket can effectively adsorb metal particles in the fluid medium, which can effectively prevent the metal particles from entering the interior of the detection seat and causing wear to the internal structure of the flow meter. After the fluid medium passes through the bracket, it begins to rotate under the guidance of the spiral guide plate and enters the interior of the separation seat. At this time, the particulate impurities in the fluid medium are transferred to the internal edge of the separation seat under the action of centrifugal force. Then, under the obstruction of the metal mesh, the particulate impurities can be effectively prevented from continuing to move with the fluid impurities, which can further prevent the internal structure of the detection seat from being worn. The overall loss level is low and the service life is effectively improved. After a period of use, the valve on the discharge pipe can be opened so that the particulate impurities collected on one side of the metal mesh can be effectively discharged. The utility model has strong practicality. Since the turbine flowmeter can separate the particulate matter in the fluid medium in advance, it can prevent the guide seat and the turbine surface from being scratched, and thus prevent the corrosion-resistant layer on the turbine surface from being damaged, and the overall corrosion resistance is effectively guaranteed.

[0023] The method of the utility model is further described in detail below with reference to the accompanying drawings.
[0024] Reference Figure 1 、 Figure 2, a low-wear, corrosion-resistant turbine flowmeter, comprising a detection seat 1, one end of the detection seat 1 is integrally connected to the separation seat 2, and a metal mesh 9 is snap-fitted on the inner side of the separation seat 2. The metal mesh 9 is annular, and a plurality of guide plates 8 are fixedly connected to the inner wall of the water inlet of the separation seat 2. The guide plates 8 are spiral-shaped, and a bracket 6 is fixedly connected to the inner wall of the water inlet of the separation seat 2. A permanent magnet steel 7 is adsorbed on the side surface of the bracket 6. The bottom of the side surface of the separation seat 2 is integrally connected to a discharge pipe 10, and a valve 5 is fixedly installed in the pipeline of the discharge pipe 10. The inlet end of the discharge pipe 10 is located on one side of the metal mesh 9. One end of the detection seat 1 and the separation seat 2 is integrally connected to a flange. When in use, the flowmeter can be installed on the conveying pipeline so that the fluid medium enters the interior of the separation seat 2 from one end of the separation seat 2. At this time, the permanent magnet steel 7 adsorbed on the side surface of the bracket 6 can effectively adsorb metal particles in the fluid medium, which can effectively prevent metal particles from entering. Entering the interior of the detection seat 1 causes wear on the internal structure of the flowmeter. After the fluid medium passes through the bracket 6, it begins to rotate under the guidance of the spiral guide plate 8 and enters the interior of the separation seat 2. At this time, the particulate impurities in the fluid medium are transferred to the internal edge of the separation seat 2 under the action of centrifugal force, and then under the obstruction of the metal mesh 9, the particulate impurities can be effectively prevented from continuing to move with the fluid impurities, and the internal structure of the detection seat 1 can be further prevented from being worn. The overall loss level is low, and the service life is effectively improved. After a period of use, the valve 5 on the discharge pipe 10 can be opened so that the particulate impurities collected on one side of the metal mesh 9 can be effectively discharged, which is highly practical. Since the turbine flowmeter can separate the particulate matter in the fluid medium in advance, it can avoid the surface of the guide seat 11 and the turbine 12 from being scratched, and thus avoid the corrosion-resistant layer on the surface of the turbine 12 from being damaged, and the overall corrosion resistance is effectively guaranteed.
[0025] Reference Figure 2 Two guide seats 11 are snap-fitted onto the inner wall of the detection seat 1, and a turbine 12 is rotatably mounted on the two guide seats 11. A mounting hole is provided on the side surface of the detection seat 1, and a magnetoresistive induction structure 3 is installed on the internal thread of the mounting hole. The magnetoresistive induction structure 3 corresponds to the position of the turbine 12. A data processing unit 4 is provided at one end of the magnetoresistive induction structure 3, and the data processing unit 4 is electrically connected to the magnetoresistive induction structure 3. After the particles in the fluid medium are separated, the fluid medium passes through the interior of the detection seat 1, and the flow of the fluid medium can effectively drive the turbine 12 to rotate. At this time, the turbine 12 can effectively cut the magnetic flux lines of the magnetoresistive induction structure 3, thereby causing the induction coil on the magnetoresistive induction structure 3 to generate current, and the current is transmitted to the interior of the data processing unit 4. After amplification and analysis by the circuit, the flow data can be effectively obtained.
[0026] Working principle: When in use, the flow meter is installed on the conveying pipeline so that the fluid medium enters the interior of the separation seat 2 from one end of the separation seat 2. At this time, the permanent magnet steel 7 adsorbed on the side surface of the bracket 6 can effectively adsorb the metal particles in the fluid medium, and can effectively prevent the metal particles from entering the interior of the detection seat 1 and causing wear on the internal structure of the flow meter. After the fluid medium passes through the bracket 6, it begins to rotate under the guidance of the spiral guide plate 8 and enters the interior of the separation seat 2. At this time, the particulate impurities in the fluid medium are transferred to the internal edge of the separation seat 2 under the action of centrifugal force, and then are blocked by the metal mesh 9, which can effectively prevent the particulate impurities from continuing to move with the fluid impurities, and can further prevent the internal structure of the detection seat 1 from being worn. The overall loss level is low, and the service life is effectively improved. After a period of use, the valve 5 on the discharge pipe 10 can be opened so that the particulate impurities collected on one side of the metal mesh 9 can be effectively discharged, which is highly practical. Since the turbine flowmeter can separate the particulate matter in the fluid medium in advance, it can avoid the surface of the guide seat 11 and the turbine 12 from being scratched, and thus avoid the corrosion-resistant layer on the surface of the turbine 12 from being damaged, and the overall corrosion resistance performance is effectively guaranteed. After the fluid medium passes through the separation seat 2, it enters the interior of the detection seat 1. The flow of the fluid medium can effectively drive the turbine 12 to rotate. At this time, the turbine 12 can effectively cut the magnetic flux lines of the magnetic resistance induction structure 3, thereby causing the induction coil on the magnetic resistance induction structure 3 to generate current, and the current is transmitted to the interior of the data processing unit 4. After amplification and analysis by the circuit, the flow data can be effectively obtained.
