Description

Technical Field

[0001] This invention relates to the field of fluid metering devices and valves, specifically to a gas flow rate metering device and valve for a gas storage tank. Background Technology

[0002] A turbine flow meter, also known as a vortex flow meter, is a common device used to measure the flow rate of gases or liquids. The basic principle of a turbine flow meter is to install a rotating turbine in the fluid. When the fluid passes through, the turbine is impacted and rotates. By designing a transmission device, the rotation of the turbine drives a counting device to measure the fluid flow rate.

[0003] However, traditional turbine flow meters also have some problems in practical applications. One major problem is the frictional resistance of the turbine rotation, which comes from the frictional force of the turbine shaft rotation and is difficult to avoid even with high-lubrication bearings. In addition, prolonged friction can lead to changes in measurement accuracy and affect the service life of the turbine. Summary of the Invention

[0041] Improved measurement accuracy: This patented invention's gas flow rate metering device for gas storage tanks employs magnetic levitation technology to suspend the turbine assembly, eliminating the need for bearings and friction. Therefore, compared to traditional vortex flow meters, there is no longer frictional resistance from the turbine shaft rotation when fluid passes through the device, thus significantly reducing measurement errors and improving the accuracy of flow rate and velocity.

[0042] Extended device lifespan: Because the suspended turbine assembly uses magnetic levitation technology, it eliminates the need for bearings, thus avoiding the lifespan limitations caused by bearing wear in traditional turbine flow meters. This reduces device wear, extends the device's service life, and lowers maintenance costs.

[0043] Reduced energy loss: The magnetic levitation technology of the suspended turbine assembly eliminates the frictional resistance of the turbine shaft rotation, making the turbine rotate more smoothly. During the measurement process, the resistance experienced by the turbine shaft is almost zero, thereby reducing energy loss and improving the measurement accuracy of the device.

[0063] The present invention provides the following preferred embodiments:

[0064] Example 1

[0065] refer to Figure 1 , Figure 3 and Figure 7 As shown, a gas flow rate metering device for a gas storage tank includes:

[0066] Support pipe assembly 1 installed between gas pipelines;

[0067] The suspension turbine assembly 2 is installed within the support tube assembly 1; and

[0068] A speed detection device 3, one end of which extends into the support tube assembly 1, is used to detect the speed of the suspension turbine assembly 2.

[0069] This embodiment describes the function of each component and device, as well as the implementation method:

[0070] Support tube assembly 1: Installed between gas pipelines, support tube assembly 1 is used to support and position the vortex flow meter device. Considering the characteristics of different fluids, support tube assembly 1 is typically made of high-temperature and corrosion-resistant materials to ensure the structural stability of the device.

[0071] Suspended turbine assembly 2: Installed within the support tube assembly 1. This suspended turbine assembly 2 utilizes magnetic levitation technology, eliminating the need for traditional bearings. It is suspended within the support tube assembly 1 by a magnetic field, thus avoiding contact between the turbine shaft and bearings and eliminating frictional resistance. The structural design of the suspended turbine assembly 2 ensures that the gas flow rate metering device in the gas storage tank has good stability and a fast response speed, guaranteeing real-time sensing of flow rate changes during gas flow.

[0072] Rotational speed detection device 3: The main body of the rotational speed detection device 3 is located outside the support tube assembly 1, with the detection end extending into it, for non-contact detection of the rotational speed of the turbine 222 in the suspension turbine assembly 2. The rotational speed detection device 3 can employ a magnetic induction sensor, photoelectric sensor, or other non-contact sensor technology. When the turbine 222 of the suspension turbine assembly 2 rotates, the rotational speed detection device 3 senses and records the rotational speed data of the turbine 222, and converts the light and magnetic signals into observable electrical signals through a conversion device.

[0073] Gas in the gas storage tank drives turbine 222 to rotate. A conversion device converts optical and magnetic signals into observable electrical signals, counts the rotation of turbine 222, and generates a pulse sequence. This sequence is then processed by the conversion device to obtain the rotational speed. To determine the gas flow rate based on the rotational speed of turbine 222, the following steps are required:

[0074] First, measure the flow coefficient corresponding to turbine 222, denoted by K. The flow coefficient is related to factors such as the shape, number of blades and area of ​​turbine 222, so it needs to be measured.

[0075] According to the formula:

[0076]

[0077] Both Kv and Cv values ​​represent flow coefficients. The difference between Kv and Cv values ​​lies in the metric and imperial units, respectively. The conversion rate is: Cv = 1.167Kv. In Formula 1, Q represents flow rate in cubic meters per second (m³). 3 / h; r represents the fluid specific gravity, in g / cm³. 3 ΔP represents the pressure difference across the valve, in units of 100 kPa. It is understandable that, according to Formula 1, we can derive the flow coefficient of the gas velocity metering device in the gas storage tank.

[0078] Then, according to the formula:

[0079]

[0080] in,

[0081] L represents air volume, and the unit is m. 3 / s;

[0082] K is the flow coefficient;

[0083] D is the outer diameter of turbine 222, in meters (m).

[0084] μ is the circumferential speed of the outer diameter of turbine 222, that is, the rotational speed, and the unit is m / s.

[0085] The flow rate of the gas in the pipeline can be calculated using Formula 2, and the flow velocity can be calculated from the flow rate. These data can be converted into observable electrical signals by a conversion device and displayed on the electronic meter 32.

[0086] Example 2

[0087] refer to Figure 2 , Figure 3 As shown, the suspended turbine assembly 2 includes:

[0088] At least one radial suspension component 21 is disposed within the support tube assembly 1;

[0089] The turbine assembly 22 is suspended within the radial suspension assembly 21; and

[0090] Two end suspension components 23 are disposed within the support tube assembly 1 and located at both ends of the turbine assembly 22.

[0091] According to the gas flow rate metering device for the gas storage tank described in Example 1, the suspension turbine assembly 2 of the device includes the following components:

[0092] At least one radial suspension component 21: At least one radial suspension component 21 is disposed within the support tube assembly 1. The radial suspension component 21 employs magnetic levitation technology, using a magnetic field to levitate the turbine assembly 22 within the support tube assembly 1, specifically within the first bracket 211 inside the support tube assembly, ensuring stable levitation of the turbine assembly 22 in the radial direction. The number of these radial suspension components 21 can be adjusted as needed to balance the self-weight of the turbine assembly 22, resulting in smoother rotation and reducing circular runout during turbine assembly 22 rotation.

[0093] Suspended turbine assembly 22: Turbine assembly 222 is suspended within radial suspension assembly 21. Turbine assembly 22 is the core component, using the kinetic energy of gas flow to drive turbine rotation. Due to the use of magnetic levitation technology, there is no contact between turbine assembly 22 and radial suspension assembly 21, thereby eliminating frictional resistance in the radial direction.

[0094] Two end suspension components 23: These two end suspension components 23 are disposed within the support tube assembly 1 and located at both ends of the turbine assembly 22. The end suspension components 23 also employ magnetic suspension technology to ensure stable levitation of the turbine assembly 22 in the axial direction. There is no contact between these two end suspension components 23 and the turbine assembly 22, eliminating frictional resistance in the axial direction.

[0095] Further optimize the design of the levitation turbine component 2:

[0096] Adjust the number of radial suspension components 21: Adjust the number of radial suspension components 21 according to specific application requirements and flow meter design requirements. Increasing the number of radial suspension components 21 can improve the stability and accuracy of the device and reduce energy loss when the turbine 222 rotates.

[0097] Optimize the shape and material of the suspension turbine assembly 22: By optimizing the shape of the turbine assembly 22 and using appropriate materials, the strength and lightweight of the turbine assembly 22 are improved, the inertial load is reduced, and the frictional resistance is further reduced.

[0098] Through the above implementation methods, the suspended turbine assembly 2 in the gas flow rate metering device of the gas storage tank in this embodiment adopts magnetic suspension technology. By setting the radial suspension assembly 21 and the end suspension assembly 23, the turbine assembly 22 can be stably suspended in the radial and axial directions, eliminating the frictional resistance between it and the rotating shaft, and further improving the measurement accuracy, stability and response speed of the device. In addition, optimizing the shape and material of the turbine assembly 22 can also reduce energy loss and improve the energy utilization efficiency of the device.

[0099] Example 3

[0100] refer to Figure 4 As shown, the radial suspension assembly 21 includes:

[0101] A first bracket 211, which is disposed within the support tube assembly 1 and has a circular through hole in the middle, is provided; and

[0102] The first circular magnet 212 is installed inside the circular through hole. The first circular magnet 212 has an inner and outer ring north-south pole type.

[0103] According to the gas flow rate metering device for the gas storage tank described in Example 2, the suspension turbine assembly 2 of the device, particularly the radial suspension assembly 21, includes the following components:

[0104] First bracket 211: A first bracket 211 is disposed inside the support tube assembly 1 and has a circular through hole in the middle. The design of the first bracket 211 ensures that the suspension turbine assembly 2 is stably suspended in the radial direction, allowing the suspension turbine assembly 2 to rotate smoothly in the gas flow. The circular through hole allows for the installation of the first circular magnet 212.

[0105] First circular magnet 212: A first circular magnet 212 is installed inside a circular through hole. This first circular magnet 212 adopts an inner and outer ring north-south pole design, and achieves a radial levitation effect through appropriate magnetic field settings. With the inner and outer ring north-south pole configuration, the first circular magnet 212 can generate a stable magnetic levitation force with the first bracket 211 in the support tube assembly 1, so that the turbine assembly 22 is suspended in the radial direction, avoiding contact with the support tube assembly 1 and eliminating frictional resistance in the radial direction.

[0106] Based on this embodiment, the design of the radial suspension component 21 is further optimized:

[0107] Material and shape optimization of the first circular magnet 212: Appropriate materials and magnet shapes were selected and optimized according to specific application requirements to improve the stability and levitation effect of the suspension turbine assembly 2. The optimized magnet design ensures stable radial levitation under various operating conditions.

[0108] Structural optimization of support tube assembly 1: The materials and structure of support tube assembly 1 are optimized to increase its stiffness and stability. This further improves the levitation effect of suspension turbine assembly 2 in the radial direction and reduces vibration and energy loss of the device.

[0109] The method of replacing permanent magnets with electromagnetism: the first circular magnet 212 can be replaced with a coil winding, and the coil density at the bottom of the first circular magnet 212 is higher than the coil density at the top. The purpose of this setting is to counteract the weight of the turbine assembly 22.

[0110] The above-described implementation includes a first bracket 211 disposed within a central circular through-hole in the support tube assembly 1, and inner and outer ring north-south pole type first circular magnets 212 installed within this through-hole. This ensures stable levitation of the suspension turbine assembly 2 in the radial direction, eliminating radial frictional resistance. By optimizing the magnet material and shape, as well as the structure of the support tube assembly 1, the levitation effect and device stability are further improved, thereby effectively enhancing the accuracy and real-time performance of the gas flow rate metering device in the gas storage tank.

[0111] Example 4

[0112] refer to Figure 3 , Figure 4 As shown, the turbine assembly 22 includes:

[0113] Rotating rod 221;

[0114] The turbine 222 is fixed on the rotating rod 221;

[0115] At least one magnet mounting base 223 is fixed on the rotating rod 221, and the magnet mounting base 223 is located inside the first circular magnet 212.

[0116] A second circular magnet 224 is mounted on the magnet mounting base 223. The second circular magnet 224 has an inner and outer ring north-south pole configuration, and the outer ring magnetic pole of the second circular magnet 224 has the opposite polarity to the inner ring magnetic pole of the first circular magnet 212.

[0117] Two first end face magnets 225 are installed at both ends of the rotating rod 221. The first end face magnets 225 are of the north and south pole type.

[0118] According to the gas flow rate metering device for the gas storage tank described in Example 3, the suspension turbine assembly 2 of the device, especially the turbine assembly 22, includes the following components:

[0119] Rotating rod 221: This rotating rod 221 is the core component of the suspended turbine assembly 2, connecting and supporting the entire turbine assembly 22 structure. The design of the rotating rod 221 should consider the stability and load-bearing capacity of the device to ensure the stability of the suspended turbine assembly 2 when operating in the fluid.

[0120] Turbine 222: Fixed to the rotating rod 221, the turbine 222 is the main power component of the suspension turbine assembly 2. The turbine 222 utilizes the kinetic energy of the gas flow to drive its rotation. The rotating rod 221 securely fixes the turbine 222 to it using a suitable fixing method, ensuring the stability and accuracy of the turbine 222 during rotation.

[0121] Magnet mounting base 223: At least one magnet mounting base 223 is fixed to the rotating rod 221, and the magnet mounting base 223 is located inside the first circular magnet 212. The magnet mounting base 223 is used to mount the second circular magnet 224 to ensure that the second circular magnet 224 can generate a stable magnetic levitation force with the first circular magnet 212.

[0122] Second circular magnet 224: A second circular magnet 224 is mounted on the magnet mounting base 223. This second circular magnet 224 also adopts an inner and outer ring north-south pole design, with the polarity opposite to that of the inner ring magnetic pole of the first circular magnet 212. Through the inner and outer ring north-south pole configuration, the second circular magnet 224 and the first circular magnet 212 generate complementary magnetic fields, achieving stable levitation of the turbine assembly 22.

[0123] First end face magnet 225: Two first end face magnets 225 are installed at both ends of the rotating rod 221. The first end face magnets 225 are of the north and south pole type. The arrangement of the first end face magnets 225 enhances the stable suspension of the turbine assembly 22 in the axial direction, maintains a stable distance between the turbine 222 and the rotating rod 221, and reduces frictional resistance.

[0124] Based on this embodiment, the design of the turbine assembly 22 can be further optimized:

[0125] Optimize the shape and material of turbine 222: Select appropriate materials and optimize the shape of turbine 222 according to application requirements to improve the strength and lightness of turbine assembly 22, reduce inertial load, and further reduce frictional resistance.

[0126] Design the position and number of magnet mounts 223: Determine the position and number of magnet mounts 223 according to specific application requirements to ensure that the turbine assembly 22 is stably suspended in the radial direction, avoids contact with the support tube assembly 1, and eliminates frictional resistance in the radial direction.

[0127] The above-described embodiments, including a rotating rod 221, a turbine 222 fixed on the rotating rod 221, a magnet mounting base 223, a second circular magnet 224, and a first end face magnet 225, enable the turbine assembly 22 to be stably suspended in the radial and axial directions, avoiding contact with the support tube assembly 1 and eliminating frictional resistance in the radial and axial directions.

[0128] Example 5

[0129] refer to Figure 2 , Figure 3 and Figure 5 As shown, the end suspension component 23 includes:

[0130] A second bracket 231, which is disposed within the support tube assembly 1 and has a circular groove in its center, and

[0131] A second end face magnet 232 is installed in the circular groove, and the second end face magnet 232 has two north and south poles on both sides;

[0132] The second end face magnet 232 is close to the first end face magnet 225, and the polarities of the two opposite sides of the second end face magnet 232 and the first end face magnet 225 are opposite.

[0133] According to the gas flow rate metering device for the gas storage tank described in Example 4, the suspension turbine assembly 2 of the device, particularly the end suspension assembly 23, includes the following components:

[0134] Second bracket 231: A second bracket 231 with a circular groove in the middle is disposed inside the support tube assembly 1. The design of the second bracket 231 ensures that the suspension turbine assembly 2 is stably suspended in the axial direction and provides sufficient support force so that the suspension turbine assembly 2 can operate in a balanced manner in the gas flow. The opening of the circular groove allows for the installation of the second end face magnet 232.

[0135] Second end magnet 232: A second end magnet 232 is installed in a circular groove and has north and south poles on both sides. The second end magnet 232 is close to the first end magnet 225, and the polarities of the north and south poles on both sides are opposite. By configuring the relative polarities of the two end magnets, a stable levitation effect is achieved for the end suspension assembly 23.

[0136] Based on this embodiment, the design of the end suspension component 23 can be further optimized:

[0137] Design the depth and dimensions of the circular groove: Design the depth and dimensions of the circular groove according to specific application requirements to ensure that the second end face magnet 232 is fixed and stable in the suspension turbine assembly 2 and achieves a corresponding relative position with the first end face magnet 225.

[0138] Optimize the shape and material of the second end face magnet 232: Select appropriate materials and optimize the shape of the second end face magnet 232 according to application requirements to improve its stability and levitation effect, and ensure the high accuracy and performance of the device in gas flow.

[0139] The above-described embodiments, including a second bracket 231 disposed in a central circular groove within the support tube assembly 1 and two north-south pole type second end face magnets 232 installed within the circular groove, ensure stable levitation of the end suspension assembly 23 in the axial direction, maintaining a stable relative position with the first end face magnet 225, further eliminating contact with the support tube assembly 1, and reducing frictional resistance in the axial direction. By optimizing the design of the circular groove and the shape and material of the second end face magnets 232, the stability and levitation effect of the end suspension assembly 23 are further improved.

[0140] Example 6

[0141] refer to Figure 4 As shown, the first circular magnet 212 is rotatably installed in the circular through hole. The mass of the lower part of the first circular magnet 212 is greater than the mass of the upper part, and the magnetic induction intensity of the lower part of the first circular magnet 212 is greater than the magnetic induction intensity of the upper part.

[0142] According to the gas flow rate metering device for the gas storage tank described in Example 3, the suspension turbine assembly 2 of the device, especially the turbine assembly 22, includes the following components:

[0143] First circular magnet 212: The first circular magnet 212 is rotatably mounted inside a circular through hole. This first circular magnet 212 has a mass distribution that is larger at the bottom and smaller at the top. The lower mass is greater than the upper mass, and the lower magnetic induction intensity is also greater than the upper magnetic induction intensity. The purpose of this design is that, when the gas flow rate metering device in the gas storage tank is horizontally installed, regardless of how it rotates along the axis, the larger mass of the lower part of the first circular magnet 212 can rotate accordingly. Simultaneously, because the lower magnetic induction intensity is greater than the upper magnetic induction intensity, it can adaptively counteract the gravity of the turbine assembly 22.

[0144] In this embodiment, the asymmetric mass distribution and magnetic induction intensity distribution of the first circular magnet 212 can be achieved by adjusting the material density or magnetic distribution of the magnet. Since the magnetic induction intensity at the lower part is greater than that at the upper part, when the levitation turbine assembly 2 operates in the gas flow, the lower part has a larger magnetic induction intensity, generating a stronger magnetic levitation force, which counteracts the gravity of the turbine assembly 22, making the turbine assembly 22 stably levitate in the radial direction.

[0146] The turbine 222 is made of lightweight material.

[0147] According to the gas flow rate metering device for the gas storage tank described in Example 4, the turbine 222 part of the suspended turbine assembly 2 of the device is made of lightweight material.

[0148] In this embodiment, the turbine 222 can be manufactured using lightweight alloys, carbon fiber composites, or other high-strength lightweight materials. The purpose of using lightweight materials to manufacture the turbine 222 is to reduce the mass of the turbine 222, reduce the inertial load, and thus reduce the energy required for the turbine 222 to rotate.

[0149] By using lightweight materials to manufacture the turbine 222, its mass can be effectively reduced, lowering its inertial load and making it easier for the turbine 222 to achieve rapid response and stable suspension in gas flow. Furthermore, the lightweight materials possess excellent strength and stiffness, ensuring the stability and durability of the turbine 222 in the fluid.
